Background: Psychosocial stress is recognized as a risk factor for coronary heart disease (CHD). High rates of CHD in African-Americans may be related to psychosocial stress. However, standard cardiac rehabilitation (CR) usually does not include a systematic stress-reduction technique. Previous studies suggest that the Transcendental Meditation (TM) technique may reduce CHD risk factors and clinical events. This pilot study explored the effects of standard CR with and without TM on a measure of CHD in African-American patients., Methods: Fifty-six CHD patients were assigned to CR, CR + TM, TM alone, or usual care. Testing was done at baseline and after 12 weeks. The primary outcome was myocardial flow reserve (MFR) assessed by 13 N-ammonia positron emission tomography (PET). Secondary outcomes were CHD risk factors. Based on guidelines for analysis of small pilot studies, data were analyzed for effect size (ES)., Results: For 37 patients who completed posttesting, there were MFR improvements in the CR + TM group (+20.7%; ES = 0.64) and the TM group alone (+12.8%; ES = 0.36). By comparison, the CR-alone and usual care groups showed modest changes (+ 5.8%; ES = 0.17 and - 10.3%; ES = - 0.31), respectively. For the combined TM group, MFR increased (+ 14%, ES = 0.56) compared to the combined non-TM group (- 2.0%, ES = - 0.08)., Conclusions: These pilot data suggest that adding the TM technique to standard cardiac rehabilitation or using TM alone may improve the myocardial flow reserve in African-American CHD patients. These results may be applied to the design of controlled clinical trials to definitively test these effects., Trial Registration: ClinicalTrials.gov registration # NCT01810029., (© 2019.

Background: Diabetes mellitus (DM) and depression are bidirectionally interrelated. We recently identified long-term trajectories of depression symptom severity in individuals with coronary heart disease (CHD), which were associated with the risk for subsequent cardiovascular events (CVE). We now investigated the prognostic value of these trajectories of symptoms of depression with the risk of incident DM in patients with stable coronary heart disease., Methods: The KAROLA cohort included CHD patients participating in an in-patient rehabilitation program (years 1999/2000) and followed for up to 15 years. We included 1048 patients (mean age 59.4 years, 15% female) with information on prevalent DM at baseline and follow-up data. Cox proportional hazards models were used to model the risk for incident DM during follow-up by depression trajectory class adjusted for age, sex, education, smoking status, body mass index, and physical activity. In addition, we modeled the excess risk for subsequent CVE due to incident DM during follow-up for each of the depression trajectories., Results: DM was prevalent in 20.7% of patients at baseline. Over follow-up, 296 (28.2%) of patients had a subsequent CVE. During follow-up, 157 (15.0%) patients developed incident DM before experiencing a subsequent CVE. Patients following a high-stable depression symptom trajectory were at substantially higher risk of developing incident DM than patients following a low-stable depression symptom trajectory (hazard ratio (HR) = 2.50; 95% confidence interval (CI) (1.35, 4.65)). A moderate-stable and an increasing depression trajectory were associated with HRs of 1.48 (95%-CI (1.10, 1.98)) and 1.77 (95%-CI (1.00, 3.15)) for incident DM. In addition, patients in the high-stable depression trajectory class who developed incident DM during follow-up were at 6.5-fold risk (HR = 6.51; 95%-CI (2.77, 15.3)) of experiencing a subsequent cardiovascular event., Conclusions: In patients with CHD, following a trajectory of high stable symptoms of depression was associated with an increased risk of incident DM. Furthermore, incident DM in these patients was associated with a substantially increased risk of subsequent CVE. Identifying depressive symptoms and pertinent treatment offers might be an important and promising approach to enhance outcomes in patients with CHD, which should be followed up in further research and practice.

Background: Percutaneous coronary intervention (PCI) is an effective revascularization strategy in patients with coronary heart disease (CHD). However, recent studies had indicated that postPCI patients usually suffer from a low-quality life. Cardiac rehabilitation (CR) has been recommended by numerous guidelines in the clinic for these patients. And Baduanjin exercise can significantly benefit patients with CHD. Regrettably, the effect of Baduanjin exercise on postPCI patients is still not clear. Therefore, this systematic review and meta-analysis protocol is planned to explore the effect of Baduanjin exercise in patients with CHD who have undergone PCI., Methods: PubMed, Excerpta Medica Database, Cochrane Library, Web of Science, Wanfang Database, SINOMED, China Science and Technology Journal Database, and China National Knowledge Infrastructure will be searched for appropriate articles from respective inceptions until December 1th, 2020. Two reviewers will independently conduct article selection, data collection, and risk of bias evaluation. Disagreements will be resolved first by discussion and then by consulting a third author for arbitration. The primary outcome will include left ventricular ejection fraction. And the change in the scores on the Seattle Angina Questionnaire, SF-36 health survey scale, Zung Self-rating Anxiety scale and self-rating depression scale will be used as the secondary outcomes. RevMan 5.3 will be used for meta-analysis., Results: This systematic review and meta-analysis will explore whether Baduanjin exercise is an effective intervention in postPCI patients., Conclusion: This systematic review and meta-analysis will provide convincing evidence of Baduanjin exercise that specifically focuses on CR of Baduanjin exercise on CHD after PCI., Registration Number: INPLASY202130065., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2021 the Author(s).

This study investigated an alternative home-based cardiac telerehabilitation model in consideration of the recommendations for the COVID-19 quarantine of people diagnosed with coronary heart disease (CHD). We hypothesized that using a 200 m fast walking test (200 mFWT) and telerehabilitation would create an effective alternative cardiac rehabilitation (CR) intervention that could improve cardiorespiratory fitness. Participants ( n = 19, mean age 60.4 ± 9.6) of the 8-week intervention performed regular physical exercise at the target heart rate zone determined by calculations based on the 200 mFWT results. In our study, the participants were supervised using telerehabilitation. A total of 84% of participants completed the 8-week intervention. No adverse events were reported during telerehabilitation. The study participants noted a significant improvement ( p < 0.001) in cardiorespiratory fitness expressed by an 8% reduction in the walking test time (Δ 8.8 ± 5.9 s). Home-based telerehabilitation based on 200 mFWT effectively increased the cardiorespiratory fitness in people with CHD with a low to moderate cardiovascular risk. This was a novel approach in CR during the COVID-19 pandemic. As research in this area is justified, this paper may serve as an alternative method of providing healthcare during the COVID-19 pandemic and as a basis for further upcoming randomized controlled trials.

Purpose: Depression and anxiety have been extensively associated with adverse outcomes in coronary heart disease patients. However, psychological and physiological processes underlying the persistence of these troubles in coronary heart disease patients attending cardiac rehabilitation are poorly investigated. Trait emotional competencies and heart rate variability could be some of these processes. Thus, the aim of this study was to assess the predictive value of trait emotional competencies and heart rate variability on depression and anxiety symptoms persistence in coronary heart disease patients., Methods: Eighty-four patients who recently presented a myocardial infarction were evaluated at the beginning of cardiac rehabilitation. Forty-two patients continued their rehabilitation program and were then assessed three months later. They completed the Profile of Emotional Competence as well as the Hospital Anxiety and Depression Scale and underwent a 5-minute resting heart rate variability measure., Results: Low trait emotional competencies score predicted depression symptoms persistence, but unexpectedly, high trait emotional competencies score was also associated with withdrawal from cardiac rehabilitation. Contrary to our expectations, heart rate variability did not predict depression or anxiety symptoms persistence and was not associated with trait emotional competencies., Conclusions: This study is the first to report an association between trait emotional competencies and depression symptoms persistence in coronary heart disease patients. However, heart rate variability was not associated with either depression or anxiety supporting the idea of mixed literature and highlighting the need of future research.

Cardiac rehabilitation is a package of lifestyle secondary prevention strategies designed for patients with coronary heart disease and chronic heart failure. A community-based cardiac rehabilitation programme provides patients with a structured exercise training intervention alongside educational support and psychological counselling. This review provides an update regarding the clinical benefits of community-based cardiac rehabilitation from a psycho-physiological perspective, and also focuses on the latest epidemiological evidence regarding potential survival benefits. Behaviour change is key to long-term adoption of a healthy and active lifestyle following a cardiac event. In order for lifestyle interventions such as structured exercise interventions to be adopted by patients, practitioners need to ensure that behaviour change programmes are mapped against patient's priorities and values, and adapted to their level of readiness and intention to engage with the target behaviour. We review the evidence regarding behaviour change strategies for cardiac patients and provide practitioners with the latest guidance. The 'dose' of exercise training delivered to patients attending exercise-based cardiac rehabilitation is an important consideration because an improvement in peak oxygen uptake requires an adequate physiological stimulus to invoke positive physiological adaptation. We conclude by critically reviewing the latest evidence regarding exercise dose for cardiac patients including the role of traditional and more contemporary training interventions including high intensity interval training., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Introduction: Cardiovascular diseases are the world's most common causes of morbidity and mortality in the population, including Central Europe. Cardiac rehabilitation (CR) is an effective preventive approach that includes several core components. Physical training is identified as an integral and essential part of CR. Training can positively influence several cardiovascular risk factors in people diagnosed with coronary heart disease and prevent them from clinical events. Our study aims to research the method of high-intensity interval training (HIIT) in a home environment using telerehabilitation. We assume that the HIIT form of telerehabilitation, using a heart rate monitor as a tool for backing up training data, can improve cardiorespiratory fitness and lead to higher peak oxygen uptake than the traditional moderate-intensity continuous training (MICT)., Methods: This study is designed as a monocentral randomized controlled trial at University Hospital Brno in the Czech Republic. After the coronary heart event, the suitable patients will be randomized (1:1 ratio) and separated into 2 groups: the experimental HIIT group and the control MICT group. Both groups undergo a 12-week telerehabilitation with a 1-year follow-up period. Study participants will be telemonitored during physical training in their home environment via a heart rate monitor and a web platform. Once a week, the patients will give their feedback and motivation by a telephone call.The primary outcome observed will be the effect of intervention expressed by changes in cardiorespiratory fitness. Secondary outcomes will be the health-related quality of life, anxiety, training adherence, body composition, safety, and satisfaction., Discussion: The HIIT is widely researched predominantly in a center-based supervised form. Our study differs from others by the use of telemedicine and smart technologies in home-based settings. Previous home-based cardiac telerehabilitation studies have focused primarily on MICT, which has demonstrated feasibility, and results have shown similar improvements as center-based CR. There is a presumption that HIIT may be superior to MICT. However, it can be complicated to self-dose the method in the home environment. Investigators expect that HIIT research will provide insight into the possibilities of telemedicine feasibility, effect, and limitations of coronary heart disease patients' use at low to moderate cardiovascular risk.

Background: Cardiac rehabilitation is effective after coronary heart disease (CHD). However, risk factors remain, and patients report fear for recurrence during recovery. Problem-based learning is a pedagogical method, where patients work self-directed in small groups with problem solving of real-life situations to manage CHD risk factors and self-care. We aimed to demonstrate the better effectiveness of problem-based learning over home-sent patient information for evaluating long-term effects of patient empowerment and self-care in patients with CHD. Hypothesis tested: One year of problem-based learning improves patients' empowerment- and self-efficacy, to change self-care compared to 1 year of standardised home-sent patient information after CHD., Methods: Patients (N = 157) from rural and urban areas in Sweden between 2011 and 2015 (78% male; age. 68 ± 8.5 years) with CHD verified by percutaneous coronary intervention (PCI) (70.1%) or coronary artery by-pass surgery (CABG) and CABG+PCI or myocardial infarction (29.9%) were randomly assigned to problem-based learning (experimental group; n = 79) or home-sent patient information (controls; n = 78). The problem-based learning intervention consisted of patient education in primary care by nurses tutoring groups of 6-9 patients on 13 occasions over 1 year. Controls received home-sent patient information on 11 occasions during the study year., Results: At one-year follow-up, the primary outcome, patient empowerment, did not significantly differ between the experimental group and controls. We found no significant differences between the groups regarding the secondary outcomes e.g. self-efficacy, although we found significant differences for body mass index (BMI) [- 0.17 (SD 1.5) vs. 0.50 (SD 1.6), P = 0.033], body weight [- 0.83 (SD) 4.45 vs. 1.14 kg (SD 4.85), P = 0.026] and HDL cholesterol [0.1 (SD 0.7) vs. 0.0 mmol/L (SD 0.3), P = 0.038] favouring the experimental group compared to controls., Conclusions: The problem-based learning- and the home-sent patient information interventions had similar results regarding patient empowerment, self-efficacy, and well-being. However, problem-based learning exhibited significant effects on weight loss, BMI, and HDL cholesterol levels, indicating that this intervention positively affected risk factors compared to the home-sent patient information., Trial Registration: NCT01462799 (February 2020).

The aim of this study was to investigate the effects of telemonitored exercise rehabilitation on patients with coronary heart disease (CHD) in China. Ninety-six patients with stable CHD were included and analyzed (48 in telemonitored group and 48 in control group). All patients received routine follow-up, and patients in telemonitored group participated in smartphone-based telemonitored cardiac rehabilitation. Patients' demographic information, medical history, diagnosis and treatment of CHD, and laboratory results were collected. The difference of cardiopulmonary exercise testing (CPET), blood test, and echocardiographic parameters; exercise habits; control rate of blood lipid and blood glucose; and incidence of adverse events between the two groups during 6 months of follow-up was analyzed. After intervention, the subjects in the telemonitored group performed significantly better in VO 2peak , exercise compliance, and some other parameters than those in the control group. Telemonitored exercise rehabilitation is an effective rehabilitation mode for CHD patients in China.

Introduction: Preliminary evidence from clinical observations suggests that Tai Chi exercise may offer potential benefits for patients with chronic coronary syndrom (CCS). However, the advantages for CCS patients to practice Tai Chi exercise as rehabilitation have not been rigorously tested and there is a lack of consensus on its benefits. This study aims to develop an innovative Tai Chi Cardiac Rehabilitation Program (TCCRP) for CCS patients and to assess the efficacy, safety and acceptability of the programme., Methods and Analysis: We propose to conduct a multicentre randomised controlled clinical trial comprising of 150 participants with CCS. The patients will be randomly assigned in a 1:1 ratio into two groups. The intervention group will participate in a supervised TCCRP held three times a week for 3 months. The control group will receive supervised conventional exercise rehabilitation held three times a week for 3 months. The primary and secondary outcomes will be assessed at baseline, 1 month, 3 months after intervention and after an additional 3-month follow-up period. Primary outcome measures will include a score of 36-Item Short Form Survey and Chinese Perceived Stress Scale. The secondary outcome measures will include body composition, cardiopulmonary exercise test, respiratory muscle function, locomotor skills, echocardiogram, New York Heart Association classification, heart rate recovery time and laboratory examination. Other measures also include Seattle Angina Scale, Pittsburgh Sleep Quality Index, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 and Berg Balance Scale. All adverse events will be recorded and analysed., Ethics and Dissemination: This study conforms to the principles of the Declaration of Helsinki and relevant ethical guidelines. Ethical approval has been obtained from the Ethics Committee of Chinese People's Libration Army General Hospital (approval number: S2019-060-02). Findings from this study will be published and presented at conferences for widespread dissemination of the results., Trial Registration Number: NCT03936504., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Aims: Prescribed exercise is effective in adults with coronary heart disease (CHD), chronic heart failure (CHF), intermittent claudication, body mass index (BMI) ≥25 kg/m 2 , hypertension or type 2 diabetes mellitus (T2DM), but the evidence for its cost-effectiveness is limited, shows large variations and is partly contradictory. Using World Health Organization and American Heart Association/American College of Cardiology value for money thresholds, we report the cost-effectiveness of exercise therapy, exercise training and exercise-based cardiac rehabilitation., Methods: Electronic databases were searched for incremental cost-effectiveness and incremental cost-utility ratios and/or the probability of cost-effectiveness of exercise prescribed as therapy in economic evaluations conducted alongside randomized controlled trials (RCTs) published between 1 July 2008 and 28 October 2018., Results: Of 19 incremental cost-utility ratios reported in 15 RCTs in patients with CHD, CHF, intermittent claudication or BMI ≥25 kg/m 2 , 63% met both value for money thresholds as 'highly cost-effective' or 'high value', with 26% 'not cost-effective' or of 'low value'. The probability of intervention cost-effectiveness ranged from 23 to 100%, probably due to the different populations, interventions and comparators reported in the individual RCTs. Confirmation with the Consolidated Health Economic Evaluation Reporting checklist varied widely across the included studies., Conclusions: The findings of this review support the cost-effectiveness of exercise therapy in patients with CHD, CHF, BMI ≥25 kg/m 2 or intermittent claudication, but, with concerns about reporting standards, need further confirmation. No eligible economic evaluation based on RCTs was identified in patients with hypertension or T2DM.

Introduction: The benefits of cardiac rehabilitation (CR) on the reduction of cardiac and all-cause mortality are well documented. However, adherence remains suboptimal in China. It is clear that traditional CR does not meet the needs of many eligible patients and innovation is required to improve its application. Home-based CR (HBCR) is a cost-effective method that may be a valuable alternative for many individuals in China. In HBCR, it is often difficult to maintain an exercise intensity that is both effective and within safe limits, factors that are essential for patient safety. Mobile health interventions have the potential to overcome these obstacles and may be efficacious in improving adherence. The purpose of this study is to evaluate whether an Intelligent Exercise Rehabilitation Management System (IERMS)-based HBCR could improve adherence to CR and to assess the effects on exercise capacity, mental health, self-efficacy, quality of life and lifestyle-related risk factors., Methods and Analysis: We propose a single-blinded, two-arm, randomised controlled crossover study of 70 patients with coronary heart disease (CHD). Participants will be randomly assigned in a 1:1 ratio to one of the two groups. Patients in group 1 will receive the IERMS intervention together with usual care for the first 6 weeks and usual care for the last 6 weeks, while patients assigned to group 2 will receive usual care for the first 6 weeks and will use IERMS in the last 6 weeks. The primary outcome is adherence to the programme and secondary outcomes include exercise capacity, psychological well-being, quality of life, self-efficacy and lifestyle-related risk factors. All secondary outcomes will be measured at baseline, 6 weeks and 12 weeks., Ethics and Dissemination: This study has been approved by the Human Research Ethics Committee of the School of Nursing, Jilin University (HREC 2019120901). The results will be published in peer-reviewed journals and at conferences., Trial Registration Number: ChiCTR1900028182; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Vocational support is recommended for patients in cardiac rehabilitation (CR), as returning to work is important in patients social readjusting after an acute coronary event. Information is lacking on whether CR leads to higher long-term employment after percutaneous coronary intervention (PCI)., Aims: The aims of this study were to determine employment status three years after PCI, to compare employment status between CR participants and CR non-participants and to assess predictors for employment., Methods: We included first-time PCI patients from the NorStent trial, who were of working age (<63 years; n = 2488) at a three-year follow-up. Employment status and CR participation were assessed using a self-report questionnaire. Propensity score method was used in comparing employment status of CR participants and CR non-participants., Results: Seventy per cent of participants who were <60 years of age at the index event were employed at follow-up and CR participation had no effect on employment status. Being male, living with a partner and attaining higher levels of education were associated with a higher chance of being employed, while being older, prior cardiovascular morbidity and smoking status were associated with lower chance of being employed at follow-up., Conclusion: Because a significant number of working-age coronary heart disease patients are unemployed three years after coronary revascularization, updated incentives should be implemented to promote vocational support. Such programmes should focus on females, patients lacking higher education and patients who are living alone, as they are more likely to remain unemployed.

Background: In the United Kingdom (UK), exercise intensity is prescribed from a fixed percentage range (% heart rate reserve (%HRR)) in cardiac rehabilitation programmes. We aimed to determine the accuracy of this approach by comparing it with an objective, threshold-based approach incorporating the accurate determination of ventilatory anaerobic threshold (VAT). We also aimed to investigate the role of baseline cardiorespiratory fitness status and exercise testing mode dependency (cycle vs . treadmill ergometer) on these relationships., Design and Methods: A maximal cardiopulmonary exercise test was conducted on a cycle ergometer or a treadmill before and following usual-care circuit training from two separate cardiac rehabilitation programmes from a single region in the UK. The heart rate corresponding to VAT was compared with current heart rate-based exercise prescription guidelines., Results: We included 112 referred patients (61 years (59-63); body mass index 29 kg·m -2 (29-30); 88% male). There was a significant but relatively weak correlation ( r  = 0.32; p  = 0.001) between measured and predicted %HRR, and values were significantly different from each other ( p  = 0.005). Within this cohort, we found that 55% of patients had their VAT identified outside of the 40-70% predicted HRR exercise training zone. In the majority of participants (45%), the VAT occurred at an exercise intensity <40% HRR. Moreover, 57% of patients with low levels of cardiorespiratory fitness achieved VAT at <40% HRR, whereas 30% of patients with higher fitness achieved their VAT at >70% HRR. VAT was significantly higher on the treadmill than the cycle ergometer ( p <  0.001)., Conclusion: In the UK, current guidelines for prescribing exercise intensity are based on a fixed percentage range. Our findings indicate that this approach may be inaccurate in a large proportion of patients undertaking cardiac rehabilitation.

Background: Tobacco smoking is one of the most important risk factors of coronary heart disease (CHD). Hence, smoking cessation is considered pivotal in the prevention of CHD. The current study aimed to evaluate smoking cessation patterns and determine factors associated with smoking cessation in patients with established CHD., Methods: The fourth European Survey of Cardiovascular Disease Prevention and Diabetes investigated quality of CHD care in 24 countries across Europe in 2012/13. In the German subset, smoking cessation patterns and clinical characteristics were repetitively assessed a) during index event due to CHD by medical record abstraction, b) as part of a face-to-face interview 6 to 36 months after the index event (i.e. baseline visit), and c) by telephone-based follow-up interview two years after the baseline visit. Logistic regression analysis was performed to search for factors determining smoking status at the time of the telephone interview., Results: Out of 469 participants available for follow-up, 104 (22.2%) had been classified as current smokers at the index event. Of those, 65 patients (62.5%) had quit smoking at the time of the telephone interview, i.e., after a median observation period of 3.5 years (quartiles 3.0, 4.1). Depressed mood at baseline visit and higher education level were less prevalent amongst quitters vs non-quitters (17.2% vs 35.9%, p = 0.03 and 15.4% vs 33.3%, p = 0.03), cardiac rehabilitation programs were more frequently attended by quitters (83.1% vs 48.7%, p < 0.001), and there was a trend for a higher prevalence of diabetes at baseline visit in quitters (37.5% vs 20.5%, p = 0.07). In the final multivariable model, cardiac rehabilitation was associated with smoking cessation (OR 5.19; 95%CI 1.87 to 14.46; p = 0.002)., Discussion: Attending a cardiac rehabilitation program after a cardiovascular event was associated with smoking cessation supporting its use as a platform for smoking cessation counseling and relapse prevention.

Aims: To evaluate the effects of eHealth cardiac rehabilitation (CR) on health outcomes of coronary heart disease patients and to identify programme design, which may lead to more effective health benefits., Design: A systematic review and meta-analysis following Cochrane Handbook for Systematic Reviews of Interventions., Data Sources: Medline, EMBASE, CLNAHL, Web of Science, Scopus, PsycINFO, Cochrane Central Register of Controlled Trails, PubMed and CNKI were searched over the period from 1806 to April 2019., Review Methods: A systematic review and meta-analysis of randomized controlled trials to examine the effect of eHealth CR on health outcomes of coronary heart disease patients. We used RevMan 5.3 for risk of bias assessment and meta-analysis and GRADE software for generating findings., Results: In all, 14 trials with 1,783 participants were included. eHealth CR has significantly promoted duration of physical activity, daily steps, quality of life (QoL) and re-hospitalization. Using comparative analysis of programme design elements, including mode of delivery, intervention content, motivational strategies and social support, between the effective and ineffective eHealth CR, it was found that comprehensive empowerment strategies and follow-up care by tele-monitoring may be the crucial characteristics leading to more favourable treatment effect., Conclusion: eHealth CR is effective in engaging patients in active lifestyle, improving QoL and reducing re-hospitalization. Future research needs to test the effects of comprehensive CR programmes by incorporating empowerment strategies and tele-monitoring as active components., Impact: eHealth has been increasingly applied to increase accessibility and uptake of CR. Integrative evidence to indicate its effects on health outcomes is lacking. This review identified its positive effects on some behavioural, psychosocial and health service use outcomes. Together with insights about which programme design elements may positively shape the outcomes, this review informs the role and practice of cardiovascular nurses in promoting evidence-based eHealth CR., (© 2019 John Wiley & Sons Ltd.)

Purpose: A recent study has shown that quadriceps strength can be used to predict the level of exercise capacity in patients with coronary heart disease. We investigated whether the relationship between muscular strength and exercise capacity is also observed with handgrip strength (HGS)., Methods: We studied 443 participants (61.8 ± 11.2 yr; 78% male) who underwent coronary intervention and participated in cardiac rehabilitation between 2015 and 2018. Logistic regression was used to assess the relationship between various clinical measures (HGS, age, sex, etc) with the distance walked on a 6-minute walk test (6MWT) and maximal oxygen uptake ((Equation is included in full-text article.)O2max)., Results: Handgrip strength was related to distance walked on the 6MWT (r = 0.435, P < .001). It was the only predictor of all exercise capacity categories, and one of the strongest predictors of each exercise capacity category. An HGS of 26% of body weight predicted an achievement of a 200-m walk on the 6MWT (positive predictive value = 0.95). However, HGS <36% of body weight predicted that 500 m could not be done in 6 min (negative predictive value = 0.97). This trend was also observed in the subgroups in which (Equation is included in full-text article.)O2max was measured., Conclusion: This study demonstrates that HGS is associated with exercise capacity in coronary heart disease and can be used to predict the level of exercise capacity. These findings may contribute to setting the recommended level of daily activity as well as the level of cardiac rehabilitation in coronary heart disease.

Background: Type 2 diabetes and cardiometabolic comorbidities manifesting as the metabolic syndrome (MetS) are highly prevalent in coronary heart disease (CHD) patients attending cardiac rehabilitation (CR). The study aimed to determine the prevalence of cardiometabolic derangements and MetS, and compare post-CR clinical responses in a large cohort of CHD patients with and without diabetes., Methods: Analyses were conducted on 3953 CHD patients [age: 61.1 ± 10.5 years; 741 (18.7%) with diabetes] that completed a representative 12-week CR program. A propensity model was used to match patients with diabetes (n = 731) to those without diabetes (n = 731) on baseline and clinical characteristics., Results: Diabetic patients experienced smaller improvements in metabolic parameters after completing CR, including abdominal obesity, and lipid profiles (all P ≤ .002), compared to non-diabetic patients. For both groups, there were similar improvement rates in peak metabolic equivalents ([METs]; P < .001); however, peak METs remained lower at 12-weeks in patients with diabetes than without diabetes. At baseline, the combined prevalence of insulin resistance (IR) and diabetes was 57.3%, whereas IR was present in 48.2% of non-diabetic patients, of which rates were reduced to 48.2% and 32.8% after CR, respectively. Accordingly, MetS prevalence decreased from 25.5% to 22.3% in diabetic versus 20.0% to 13.4% in non-diabetic patients (all P ≤ .004)., Conclusions: Completing CR appears to provide comprehensive risk reduction in cardio-metabolic parameters associated with diabetes and MetS; however, CHD patients with diabetes may require additional and more aggressive attention towards all MetS criteria over the course of CR in order to prevent future cardiovascular events., (Copyright © 2019 The Authors.

Background: Adherence to medication regimens is essential for preventing and reducing adverse outcomes among patients with coronary artery disease (CAD). Greater understanding of the relation between negative illness perceptions, beliefs about cardiac rehabilitation (CR) and medication adherence may help inform future approaches to improving medication adherence and quality of life (QoL) outcomes. The aims of the study are: 1) to compare changes in illness perceptions, beliefs about CR, medication adherence and QoL on entry to a CR programme and 6 months later; 2) to examine associations between patients' illness perceptions and beliefs about CR at baseline and medication adherence and QoL at 6 months., Methods: A longitudinal study of 40 patients with CAD recruited from one CR service in Scotland. Patients completed the Medication Adherence Report Scale, Brief Illness Perception Questionnaire, Beliefs about CR questionnaire and the Short-Form 12 Health Survey. Data were analysed using the Wilcoxon Signed Ranks test, Pearson Product Moment correlation and Bayesian multiple logistic regression., Results: Most patients were men (70%), aged 62.3 mean (SD 7.84) years. Small improvements in 'perceived suitability' of CR at baseline increased the odds of being fully adherent to medication by approximately 60% at 6 months. Being fully adherent at baseline increased the odds of staying so at 6 months by 13.5 times. 'Perceived necessity, concerns for exercise and practical barriers' were negatively associated with reductions in the probability of full medication adherence of 50, 10, and 50%. Small increases in concerns about exercise decreased the odds of better physical health at 6 months by about 50%; and increases in practical barriers decreased the odds of better physical health by about 60%. Patients perceived fewer consequences of their cardiac disease at 6 months., Conclusions: Patients' beliefs on entry to a CR programme are especially important to medication adherence at 6 months. Negative beliefs about CR should be identified early in CR to counteract any negative effects on QoL. Interventions to improve medication adherence and QoL outcomes should focus on improving patients' negative beliefs about CR and increasing understanding of the role of medication adherence in preventing a future cardiac event.

Background: International cardiac rehabilitation guidelines recommend that participants meet public health physical activity guidelines. Few studies have objectively measured how much time cardiac rehabilitation participants spend in physical activity and sedentary behaviour, particularly over the long term., Objective: The aim of this study was to objectively assess physical activity and sedentary behaviour of cardiac rehabilitation participants over 12 months and determine whether they met the public health physical activity and sedentary behaviour guidelines., Methods: Cardiac rehabilitation participants with coronary heart disease were recruited in a prospective cohort study (n=72). Participants wore an ActiGraph ActiSleep accelerometer for 7 consecutive days at baseline, 6 weeks, and 6 and 12 months to assess daily minutes of moderate-to-vigorous physical activity and sedentary behaviour (<100 counts/min). Other outcomes collected were self-reported physical activity and sedentary behaviour, body mass index, waist-to-hip ratio, lipid profile, blood glucose level, quality of life, exercise capacity, anxiety and depression., Results: By intent-to-treat analysis, during the 6-week cardiac rehabilitation program, participants increased their light physical activity (P<0.01), which was maintained up to 12 months. Moderate-to-vigorous physical activity and sedentary behaviour did not change during the 6-week cardiac rehabilitation program but did improve over 6 months (sedentary behaviour decreased [P<0.001], moderate-to-vigorous physical activity increased [P<0.05]), which was maintained up to 1 year. Completion of moderate-to-vigorous physical activity in 10-min bouts did not change over 12 months, nor did the proportion of participants meeting physical activity guidelines (15-21%). Sedentary behaviour remained high throughout (11 hr/day)., Conclusion: Most cardiac rehabilitation participants did not meet the physical activity guidelines during and after a 6-week program up to 12 months. Reducing sedentary behaviour may be a more achievable first-line strategy for cardiac patients, moving participants along the energy expenditure continuum, aiming to increase their physical activity levels over the medium to long term., Trial Registration: Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12615000995572, http://www.ANZCTR.org.au/ACTRN12615000995572.aspx., (Copyright © 2019 Elsevier Masson SAS.

We examined the long-term effectiveness of a group-based psychological intervention ("MoVo-LISA") to promote physical activity in patients with coronary heart disease. In this randomized controlled trial, N = 202 inactive patients with coronary heart disease were assigned to the control group (n = 102; treatment as usual) or the intervention group (n = 100; treatment as usual plus MoVo-LISA). Physical activity was assessed at baseline, 6 weeks (post-treatment), 6 months, and 12 months after discharge. ANCOVA for repeated measures revealed a significant interaction effect [p < .001; η p 2 = .214] indicating a large effect [d = 1.03] of the intervention on behavior change post-treatment. At 12-month follow-up, the level of physical activity in the intervention group was still 94 min per week higher than in the control group (p < .001; d = 0.57). Results of this RCT indicate that the MoVo-LISA intervention substantially improves the level of physical activity among initially inactive patients with coronary heart disease up to 1 year after the intervention.

Objective: This study was done to investigate the effect of preoperative peer education on patients' adherence to medication and lifestyle changes after Coronary Artery Bypass Graft (CABG)., Methods: In this randomized clinical trial, the peers of CABG patients conducted preoperative educational sessions at the ward in groups of 4-5 (n = 36) while the control group (n = 34) received routine education by a nurse. Adherence of both groups to medication and recommendations for lifestyle modification including physical activity, smoking, and diet was measured one and two months after discharge., Results: A multivariate analysis of co-variance showed the significant effect of peer education on adherence (F = 32.586, p < 0.001; η 2  = 0.671). Univariate ANCOVA revealed a significant difference in adherence to diet between the two groups (F = 62.316, p = 0 0.0001; η 2  = 0.482). Based on the repeated measures ANOVA, peer education significantly improved the CABG patients' adherence to diet (F = 55.373, p = 0.0001) and their total adherence (F = 9.911, p = 0.002) compared to the control group., Conclusion: Preoperative peer education had a significant effect on improving CABG patients' adherence to lifestyle changes after hospital discharge., Practice Implication: Peer education can be used as an effective method to improve the CABG patients ' adherence to lifestyle changes., (Copyright © 2019 Elsevier B.V.

Background: Cardiac rehabilitation (CR) uptake and adherence remain sub-optimal despite the apparent health benefits of modifying healthy behavior and slowing disease progression. eHealth is the use of information and communication technology (ICT) for health. eHealth lifestyle interventions and disease management have emerged as modalities to enhance CR accessibility, enable an individualized progress page, and enrich real-time contact, video-based information, and technology monitored functionality. This study aims to develop a nurse-led eHealth cardiac rehabilitation (NeCR) intervention and investigate its effectiveness on coronary heart disease (CHD) patients' health outcomes., Methods: This single-blinded two-arm parallel randomized controlled trial will randomize 146 patients from the inpatient cardiovascular units of a hospital in Wuhan, China to receive either the NeCR or the usual care. The NeCR intervention uses a hybrid approach consisting of a brief face-to-face preparatory phase and an empowerment phase delivered by health technology. The preparatory phase aims at identifying self-care needs, developing a goal-oriented patient centered action plan, incorporating a peer support network and orientation to the use of the e-platform. The empowerment phase includes use of the multi-media interactive NeCR for promoting symptom management, monitoring lifestyle changes and offering psychological support. A tele-care platform is also integrated to enhance health care dialogue with health professionals and peer groups. The control group will receive the usual care. An evaluation of lifestyle behavioral changes, self-efficacy, health-related quality of life, anxiety and depression, cardiovascular risk parameters, and unplanned health services use will be conducted at baseline, 6 weeks and 12 weeks post-intervention., Discussion: This protocol proposes an individualized, comprehensive, and interactive NeCR delivered using a hybrid approach and guided by an empowerment model to optimize health outcomes of CHD patients. The intervention content and web-design is based on international health guidelines to improve credibility, comprehensibility and implementation. This study also proposes a new method of peer support in which the researcher shares participants' progress toward goal attainment with the peer group. Results of this research have the potential to increase accessibility and availability of CR, improve cardiac rehabilitation service development in China, and inform eHealth lifestyle interventions., Trial Registration: Chinese Clinical Trial Registry: ChiCTR1800020411; Date of registration: December 28, 2018.

Background: Coronary heart disease is rapidly increasing in developing countries, but access to cardiac rehabilitation and secondary prevention remains low. In this study, we aimed to assess the effectiveness of a smartphone-based cardiac rehabilitation and secondary prevention programme delivered via the social media platform WeChat (SMART-CR/SP)., Methods: In this parallel-group, single-blind, randomised controlled trial, we recruited patients aged 18 years or older with coronary heart disease who had received percutaneous coronary interventions from a large tertiary hospital in Shanghai, China. Participants were randomly assigned (1:1) by block randomisation to either a 2-month intensive programme followed by a 4-month step-down phase of SMART-CR/SP or to usual care. In the SMART-CR/SP group, participants received comprehensive cardiac rehabilitation and secondary prevention via WeChat. The usual care group received standard outpatient cardiology follow-up but without formal cardiac rehabilitation and secondary prevention. Assessments were done at baseline, 2 months, 6 months, and 12 months. The primary outcome was change in functional capacity from baseline, measured by 6-min walk distance, at 2 months and 6 months. Analysis was by intention to treat. Research personnel involved in assessments were blinded to group allocation. Adverse-event analysis was based on percentage of patients who discontinued the study owing to adverse events. SMART-CR/SP programme-related safety issues were also recorded. This study was registered with the Chinese Clinical Trial Registry, number ChiCTR-INR-16009598., Findings: Between Nov 17, 2016, and March 18, 2017, 312 patients (mean age 60·5 years [SD 9·2]), of whom 58 (19%) were female and 254 (81%) were male, were recruited and subsequently randomly assigned to SMART-CR/SP (n=156) or usual care (n=156). The improvement in 6-min walk distance at 2 months was significantly greater in the SMART-CR/SP group (from 489·2 m [99·4] at baseline to 539·1 m [68·0]) than in the control group (from 485·0 m [93·5] at baseline to 517·8 m [74.6]), with an adjusted mean difference of 20·64 m (95% CI 7·50-33·77; p=0·034). This improvement was maintained at 6 months (mean 6-min walk distance 543·4 m [67·5] in the SMART-CR/SP group vs 523·5 m [60·2] in the control group), with a mean between-group difference of 22·29 m (8·19-36·38; p=0·027). No adverse events or SMART-CR/SP programme-related safety issues were reported by participants during the study., Interpretation: SMART-CR/SP was found to be a cardiac rehabilitation and secondary prevention service model with high efficacy and accessibility and to be easy to use. These results justify the implementation of similar models of care on a broader scale., Funding: Curtin University., (Copyright © 2019 The Author(s). Published by Elsevier Ltd.

Background: Coronary heart disease (CHD) can lead to loss of workability and early retirement. We aimed to investigate return to work (RTW) and its relationship towards psychosocial well-being and health-related quality of life (HRQoL)., Design: Secondary analyses were applied to cross-sectional data from the EUROASPIRE IV survey (European Action on Secondary and Primary prevention through Intervention to Reduce Events)., Methods: Participants were examined and interviewed at 6-36 months following the recruiting event. Psychosocial well-being and HRQoL were evaluated by completing the 'Hospital Anxiety and Depression Scale' and 'HeartQoL' questionnaire. Using generalised mixed models, we calculated the odds ratios for RTW. Depression, anxiety and adjusted means of HeartQoL were estimated accounting for RTW., Results: Out of 3291 employed patients, the majority (76.0%) returned to work, of which 85.6% were men, but there was a general underrepresentation of women. Young ( p  < 0.001), high-educated ( p  < 0.001) patients without prior cardiovascular events ( p  < 0.05) were better off regarding RTW. No significant associations with CHD risk factors and cardiac rehabilitation were established. Those that rejoined the workforce were less susceptible to psychosocial distress (anxiety/depression, p  < 0.001) and experienced a better quality of life ( p  < 0.001)., Conclusion: These findings provide evidence that non-modifiable factors (sociodemographic factors, cardiovascular history), more than classical risk factors, are associated with RTW, and that patients who resume work display better psychosocial well-being and HRQoL. Our results illustrate a need for tailored cardiac rehabilitation with a focus on work-related aspects, mental health and HRQoL indicators to reach sustainable RTW, especially in vulnerable groups like less educated and elderly patients.

Introduction : The aim of this review is to introduce the audience to exercise training (ET) as a therapeutic tool in coronary heart disease (CHD) and to discuss the role of and advances in cardiac rehabilitation (CR) as a means of effectively delivering ET. Areas covered : The physiological mechanisms behind ET effects on the cardiovascular (CV) system as well as the implementation of ET in CR and the effects of CR on CV morbidity, risk factor modification, and mortality will be reviewed. Additionally, the clinical and financial impact of CR in today's healthcare systems will be discussed. Expert opinion : It is well-established that CR continues to be under-utilized despite significant benefits to patients and healthcare systems alike. Innovation in the structure of CR (such as the implementation of high-intensity protocols) and in accessibility (home and tele-health CR programs) is already helping improve efficacy and increase utilization of CR. However, the efficacy of home/remote delivery protocols is not well established and they comprise a minority of available CR services. More data and efforts are needed to improve such protocols and maximize the reach of remote delivery systems in order to effectively deliver CR services to more eligible individuals at lower costs.

Background: The aim of this study was to investigate the efficacy and safety of different exercise regimens in the rehabilitation of patients with stable coronary heart disease., Patients and Methods: This study was a randomized controlled trial to screen 141 patients with stable coronary heart disease who were admitted to the General Administration of Sport of China Sports Medical Science Institute from January 2018 to September 2018. They were randomly divided into the aerobic and resistance training (ART) group for 12 weeks (36 cases), the traditional Chinese medicine training (TCMT) group 12 weeks (37 cases), and the control (CON) group (39 cases). We analyzed the baseline parameters of all participants and the 12-week exercise plate test parameters and related physical and body parameters., Result: After 12 weeks of intervention, volume of oxygen (VO2), VO2/kg, metabolic equivalents, VO2/heart rate, stroke volume, and peaked grip strength and flexibility parameters of the ART group and the TCMT group were significantly higher than those of the control group (P<0.05). Resting heart rate of the TCMT group was significantly lower than the CON group, but there was no significant difference between the ART and CON groups (P>0.05). Ventilation/VO2 of the TCMT group was significantly higher than that of the CON group. BMI of the ART group was significantly lower than that of the TCMT group and the CON group, and body fat mass of the TCMT group was significantly smaller than that of the ART group, but there was no difference between the TCMT group and the CON group for BMI and body fat mass., Conclusion: Both ART and TCMT can improve the cardiopulmonary aerobic exercise capacity and physical fitness of patients with stable coronary heart disease. Although the degree of improvement is different, they all have certain effects on the rehabilitation of patients with stable coronary heart disease and the application is safe.

This study aimed to evaluate whether near-infrared spectroscopy (NIRS)-derived reperfusion slope would detect the effects of a 12-week rehabilitation program on lower limb microvascular responsiveness in patients with coronary heart disease (CHD). Ten CHD patients (7 males and 3 females; 57.3 ± 7.6 years) underwent 12 weeks of drug treatment and high-intensity interval training (HIIT), 2 times per week (40 min/session). Microvascular responsiveness was assessed by using NIRS assessment of muscle oxygen saturation (StO 2 ) combined with a vascular occlusion test (VOT) (NIRS-VOT). NIRS-VOT measures were taken at pre- and postintervention, and microvascular responsiveness was evaluated by examining the slope 2 of re-oxygenation rate (slope 2 StO 2 ) and the area under the curve (StO 2 AUC ) of StO 2 signal following cuff release subsequent to a 5-min occlusion period. The slope 2 StO 2 was significantly steeper after 12 weeks of training (4.8 ± 1.6% sec -1 ) compared to the pretraining (3.1 ± 1.6% sec -1 ) (P < 0.05). The area under the curve for the change in the % StO 2 signal during re-oxygenation increased significantly from 3494 ± 2372%∙sec at pretraining to 9006 ± 4311%∙sec at post-training (P < 0.05). NIRS-VOT technique detected the improvements of 12 weeks of rehabilitation program in the lower limb microvascular responsiveness of CHD patients., (© 2019 The Authors.

Aim: The aim of the project was to conduct a systematic review of meta-analyses of supervised, home-based or telemedicine-based exercise cardiac rehabilitation (CR) published between July 2011 and April 2018. Materials & methods: Evidence on mortality, hospitalization, peak VO 2 , exercise capacity, muscle strength and health-related quality of life in patients with coronary heart disease or heart failure referred to CR was obtained by searching six electronic databases. Results: Of the 127 point estimates identified in the 30 CR meta-analyses identified (mortality, n = 12; hospitalization, n = 11; VO 2 , n = 40; exercise capacity, n = 20; strength, n = 18; health-related quality of life, n = 26), 60% were statistically significant and 35% clinically important. Conclusion: The statistical data are sufficiently robust to promote strategies to improve referral to and participation in CR although evidence for clinical importance needs to be further investigated.

Background and objectives: A body of evidence confirms the benefits of cardiac rehabilitation (CR) in coronary heart disease (CHD) patients, but it remains unclear whether it enhances the antioxidant potential. The aim of the study was to assess the influence of an eight-week aerobic cycloergometer-based CR program on serum total antioxidant capacity (TAC) and other CHD risk factors. Materials and Methods: The study involved 36 men with CHD (55.2 ± 9.0 years). TAC was assessed with two methods: ferric reducing ability of serum (TAC-FRAS) and 2.2-diphenyl-1-picryl-hydrazyl (TAC-DPPH). Aerobic capacity was evaluated during a submaximal exercise test. TAC and other anthropometric, biochemical and physical activity/fitness measures were performed twice: before the beginning and after termination of CR. Results: Aerobic capacity was higher (7.0 ± 2.6 vs. 8.0 ± 2.5 MET-metabolic equivalents; p < 0.01), but values of resting diastolic blood pressure were lower (81.9 ± 7.6 vs. 77.4 ± 8.9 mmHg; p < 0.01) after termination of CR. Other classic cardiometabolic, anthropometric, and biochemical measures did not change with CR. No difference in TAC-FRAS was found after CR, whereas TAC-DPPH was significantly lower (16.4 ± 4.0 vs. 13.2 ± 3.7% reduction; p < 0.01). Conclusions: Antioxidant potential measured as TAC-DPPH, but not as TAC-FRAS, decreased with the CR program. The recognized health benefits of CR are not related to augmented serum antioxidant status.

Background: Coronary heart disease (CHD) is a major cause of death worldwide. Cardiac rehabilitation, an evidence-based CHD secondary prevention programme, remains underutilized. Telehealth may offer an innovative solution to overcome barriers to cardiac rehabilitation attendance. We aimed to determine whether contemporary telehealth interventions can provide effective secondary prevention as an alternative or adjunct care compared with cardiac rehabilitation and/or usual care for patients with CHD., Methods: Relevant randomized controlled trials evaluating telehealth interventions in CHD patients with at least three months' follow-up compared with cardiac rehabilitation and/or usual care were identified by searching electronic databases. We checked reference lists, relevant conference lists, grey literature and keyword searching of the Internet. Main outcomes included all-cause mortality, rehospitalization/cardiac events and modifiable risk factors. (PROSPERO registration number 77507.)., Results: In total, 32 papers reporting 30 unique trials were identified. Telehealth was not significant associated with a lower all-cause mortality than cardiac rehabilitation and/or usual care (risk ratio (RR)=0.60, 95% confidence interval (CI)=0.86 to 1.24, p=0.42). Telehealth was significantly associated with lower rehospitalization or cardiac events (RR=0.56, 95% CI=0.39 to 0.81, p<0.0001) compared with non-intervention groups. There was a significantly lower weighted mean difference (WMD) at medium to long-term follow-up than comparison groups for total cholesterol (WMD= -0.26 mmol/l, 95% CI= -0.4 to -0.11, p <0.001), low-density lipoprotein (WMD= -0.28, 95% CI = -0.50 to -0.05, p=0.02) and smoking status (RR=0.77, 95% CI =0.59 to 0.99, p=0.04]., Conclusions: Telehealth interventions with a range of delivery modes could be offered to patients who cannot attend cardiac rehabilitation, or as an adjunct to cardiac rehabilitation for effective secondary prevention.

Background: Rehabilitation measures are crucial for maintaining clinical benefits of coronary artery bypass grafting (CABG) surgery. We evaluated the clinical efficacy of a medical centre- and home-based cardiac rehabilitation (CR) for patients after CABG in an out-patient setting., Methods: The study included 36 male patients 3-8 weeks after CABG that were randomly assigned to either study or control group. Patients from the study group performed a 60 min excercise in controlled setting 3 times a week for 4 months followed by home-based excercise later on, while patients from the control group only received a recommendation to perform the excercise at home in an uncontrolled setting. Total duration of the follow-up was 12 months., Results: Physical endurance in the study group increased by 32.6% (p <0.05) in comparison to baseline after 4 months, and was maintained at this level after 12 months, while in the control group, an improvement of 9.8% (p <0.05) was observed after 12 months. Moreover, patients from the study group demonstrated a stable level of such risk factors as blood total and low-density lipoprotein cholesterol, while in the control group, these parameters increased by 10.2% (p <0.05) and 15.6% (p <0.05) respectively by the end of follow-up. Controlled medical centre-based exercise resulted in improvement of patients' quality of life and reduction of cardiovascular complications (11.1% against 39.2% in the control group)., Conclusion: The integral (medical centre and home-based) stage III CR program after CABG helped reducing cardiovascular risk factors, and improved clinical parameters and functional capacity of patients., (Copyright © 2019 IMSS.

Coronary heart disease is a serious threat to human health. In China, medical care for the population has been focused on therapy with little follow-up of treated patients. The efficacy of therapy; however, is highly dependent on post-therapy recovery. Cardiac rehabilitation can significantly enhance patient physical strength and help delay and prevent the development of coronary atherosclerosis. Although the clinical significance of cardiac rehabilitation has been established, the compliance of patients is generally low. In efforts to improve patient compliance, domestic and foreign researchers have extensively studied and applied treatment models of cardiac rehabilitation according to the specific conditions and cultural background of each country. This study aimed to review the treatment models of cardiac rehabilitation in patients with coronary heart disease and related factors affecting patient compliance to provide a better perspective of how patients with coronary heart disease can benefit from cardiac rehabilitation., Competing Interests: The authors declare no competing interest., (© 2019 Tian et al.

Objective: Despite the growing epidemic of cardiovascular diseases in middle-income countries, there is insufficient evidence about cardiac rehabilitation (CR) in these countries. Thus, the effects of comprehensive CR on functional capacity and risk factors were investigated in Brazil, to test the hypothesis that it results in better outcomes than exercise-only or no CR., Methods: Single-blinded, randomised controlled trial with three parallel arms: comprehensive CR (exercise+education) versus exercise-only CR versus wait-list control. Eligible coronary patients were randomised in blocks of four with 1:1:1 concealed allocation. Participants randomised to exercise-only CR received 36 exercise classes; comprehensive CR group also received 24 educational sessions. The primary outcome was incremental shuttle walk test (ISWT) distance; secondary outcomes were cardiovascular risk factors. All outcomes were assessed at baseline and 6 months later. Analysis of covariance was performed on the basis of intention-to-treat (ITT) and per-protocol., Results: 115 (88.5%) patients were randomised; 93 (80.9%) were retained. There were improvements in ISWT distance from pretest to post-test with comprehensive (from 358.4±132.6 to 464.8±121.6 m; mean change=106.4; p<0.001) and exercise-only (from 391.5±118.8 to 488.1±106.3 m; mean change=96.5, p<0.001) CR, with significantly greater functional capacity with comprehensive CR versus control (ITT: mean difference=75.6±30.7 m, 95% CI 1.4 to 150.2). There were also reductions in systolic blood pressure with comprehensive CR (ITT: reduction of 6.2±17.8 mm Hg, p=0.04). There were no significant differences for other outcomes., Conclusion: Results showed clinically significant improvements in functional capacity and blood pressure with CR, and significantly greater functional capacity with comprehensive CR compared with usual care., Trial Registration Number: NCT02575976; Results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Introduction: Coronary heart disease (CHD) is the most common cause of death worldwide. Percutaneous coronary intervention (PCI) has been shown to reduce mortality in patients with CHD. However, there are still recurrences of cardiovascular events after PCI. Cardiac rehabilitation (CR) in patients with established CHD is associated with reductions in cardiovascular mortality and hospital admissions, as well as improved quality of life. More and more clinical trials suggest that traditional Chinese exercise (TCE) plays a positive role in patients post-PCI. The primary purposes of the current study are to conduct a network meta-analysis of randomised trials to determine the effects of TCE in patients after PCI, and to separately compare the effects of tai chi, baduanjin and yijinjing on CR after PCI., Methods and Analysis: Studies will be retrieved from the following databases: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Data, Chinese BioMedical Database and Chinese Science and Technology Periodicals Database, from inception to December 2018. We will include randomised controlled trials that are related to the effects of TCE therapies in patients after PCI. The primary outcomes will be all-cause mortality, revascularisations, health-related quality of life and hospitalisations. Two reviewers will independently select eligible articles. For each included article, two reviewers will independently extract the data and assess the risk of bias by using the Cochrane risk of bias tool. Bayesian network meta-analyses will be conducted to pool all treatment effects. The ranking probabilities for the optimal intervention of various treatments (tai chi, baduanjin or yijinjing) will be estimated by the mean ranks and surface under the cumulative ranking curve. The Grading of Recommendations Assessment, Development and Evaluation System will be used to assess the quality of evidence., Ethics and Dissemination: The results will be disseminated through peer-reviewed publications. They will provide consolidated evidence to inform clinicians on the potential functions of TCE in CR, and to provide reliable evidence for the application of TCE., Trial Registration Number: CRD42018088415., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: International clinical practice guidelines routinely recommend that cardiac patients participate in rehabilitation programmes for comprehensive secondary prevention. However, data show that only a small proportion of these patients utilise rehabilitation., Objectives: First, to assess interventions provided to increase patient enrolment in, adherence to, and completion of cardiac rehabilitation. Second, to assess intervention costs and associated harms, as well as interventions intended to promote equitable CR utilisation in vulnerable patient subpopulations., Search Methods: Review authors performed a search on 10 July 2018, to identify studies published since publication of the previous systematic review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL); the National Health Service (NHS) Centre for Reviews and Dissemination (CRD) databases (Health Technology Assessment (HTA) and Database of Abstracts of Reviews of Effects (DARE)), in the Cochrane Library (Wiley); MEDLINE (Ovid); Embase (Elsevier); the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCOhost); and Conference Proceedings Citation Index - Science (CPCI-S) on Web of Science (Clarivate Analytics). We checked the reference lists of relevant systematic reviews for additional studies and also searched two clinical trial registers. We applied no language restrictions., Selection Criteria: We included randomised controlled trials (RCTs) in adults with myocardial infarction, with angina, undergoing coronary artery bypass graft surgery or percutaneous coronary intervention, or with heart failure who were eligible for cardiac rehabilitation. Interventions had to aim to increase utilisation of comprehensive phase II cardiac rehabilitation. We included only studies that measured one or more of our primary outcomes. Secondary outcomes were harms and costs, and we focused on equity., Data Collection and Analysis: Two review authors independently screened the titles and abstracts of all identified references for eligibility, and we obtained full papers of potentially relevant trials. Two review authors independently considered these trials for inclusion, assessed included studies for risk of bias, and extracted trial data independently. We resolved disagreements through consultation with a third review author. We performed random-effects meta-regression for each outcome and explored prespecified study characteristics., Main Results: Overall, we included 26 studies with 5299 participants (29 comparisons). Participants were primarily male (64.2%). Ten (38.5%) studies included patients with heart failure. We assessed most studies as having low or unclear risk of bias. Sixteen studies (3164 participants) reported interventions to improve enrolment in cardiac rehabilitation, 11 studies (2319 participants) reported interventions to improve adherence to cardiac rehabilitation, and seven studies (1567 participants) reported interventions to increase programme completion. Researchers tested a variety of interventions to increase utilisation of cardiac rehabilitation. In many studies, this consisted of contacts made by a healthcare provider during or shortly after an acute care hospitalisation.Low-quality evidence shows an effect of interventions on increasing programme enrolment (19 comparisons; risk ratio (RR) 1.27, 95% confidence interval (CI) 1.13 to 1.42). Meta-regression revealed that the intervention deliverer (nurse or allied healthcare provider; P = 0.02) and the delivery format (face-to-face; P = 0.01) were influential in increasing enrolment. Low-quality evidence shows interventions to increase adherence were effective (nine comparisons; standardised mean difference (SMD) 0.38, 95% CI 0.20 to 0.55), particularly when they were delivered remotely, such as in home-based programs (SMD 0.56, 95% CI 0.37 to 0.76). Moderate-quality evidence shows interventions to increase programme completion were also effective (eight comparisons; RR 1.13, 95% CI 1.02 to 1.25), but those applied in multi-centre studies were less effective than those given in single-centre studies, leading to questions regarding generalisability. A moderate level of statistical heterogeneity across intervention studies reflects heterogeneity in intervention approaches. There was no evidence of small-study bias for enrolment (insufficient studies to test for this in the other outcomes).With regard to secondary outcomes, no studies reported on harms associated with the interventions. Only two studies reported costs. In terms of equity, trialists tested interventions designed to improve utilisation among women and older patients. Evidence is insufficient for quantitative assessment of whether women-tailored programmes were associated with increased utilisation, and studies that assess motivating women are needed. For older participants, again while quantitative assessment could not be undertaken, peer navigation may improve enrolment., Authors' Conclusions: Interventions may increase cardiac rehabilitation enrolment, adherence and completion; however the quality of evidence was low to moderate due to heterogeneity of the interventions used, among other factors. Effects on enrolment were larger in studies targeting healthcare providers, training nurses, or allied healthcare providers to intervene face-to-face; effects on adherence were larger in studies that tested remote interventions. More research is needed, particularly to discover the best ways to increase programme completion.

Background: Mechanical efficiency (ME) refers to the ability of an individual to transfer energy consumed by external work. A decreased ME, could represent an increased energy cost during exercise and may, therefore, be limited in terms of physical activity. This study aimed to compare the influence of two different exercise protocols: moderate continuous training (MCT) versus high intensity interval training (HIIT), as part of a cardiac rehabilitation program on ME values among coronary patients., Methods: One hundred and ten coronary patients were assigned to either HIIT or MCT groups for 8 weeks. Incremental exercise tests in a cycle ergometer were performed to obtain VO2peak. Net energy expenditure (EE) and ME were obtained at intensities corresponding to the first (VT1) and second (VT2) ventilatory thresholds, and at VO2peak., Results: Both exercise programs significantly increase VO2peak with a higher increase in the HIIT group (2.96 ± 2.33 mL/kg/min vs. 3.88 ± 2.40 mL/kg/min, for patients of the MCT and HIIT groups, respectively, p < 0.001). The ME at VO2peak and VT2 only significantly increased in the HIIT group. At VT1, ME significantly increased in both groups, with a greater increase in the HIIT group (2.20 ± ± 6.25% vs. 5.52 ± 5.53%, for patients of the MCT and HIIT groups, respectively, p < 0.001)., Conclusions: The application of HIIT to patients with chronic ischemic heart disease of low risk re- sulted in a greater improvement in VO2peak and in ME at VT1, than when MCT was applied. Moreover, only the application of HIIT brought about a significant increase in ME at VT2 and at VO2peak.

Objective: Compare the effects and costs of remotely monitored exercise-based cardiac telerehabilitation (REMOTE-CR) with centre-based programmes (CBexCR) in adults with coronary heart disease (CHD)., Methods: Participants were randomised to receive 12 weeks of telerehabilitation or centre-based rehabilitation. REMOTE-CR provided individualised exercise prescription, real-time exercise monitoring/coaching and theory-based behavioural strategies via a bespoke telerehabilitation platform; CBexCR provided individualised exercise prescription and coaching via established rehabilitation clinics. Outcomes assessed at baseline, 12 and/or 24 weeks included maximal oxygen uptake (V̇O 2 max, primary) modifiable cardiovascular risk factors, exercise adherence, motivation, health-related quality of life and programme delivery, hospital service utilisation and medication costs. The primary hypothesis was a non-inferior between-group difference in V̇O 2 max at 12 weeks (inferiority margin=-1.25 mL/kg/min); inferiority margins were not set for secondary outcomes., Results: 162 participants (mean 61±12.7 years, 86% men) were randomised. V̇O 2 max was comparable in both groups at 12 weeks and REMOTE-CR was non-inferior to CBexCR (REMOTE-CR-CBexCR adjusted mean difference (AMD)=0.51 (95% CI -0.97 to 1.98) mL/kg/min, p=0.48). REMOTE-CR participants were less sedentary at 24 weeks (AMD=-61.5 (95% CI -117.8 to -5.3) min/day, p=0.03), while CBexCR participants had smaller waist (AMD=1.71 (95% CI 0.09 to 3.34) cm, p=0.04) and hip circumferences (AMD=1.16 (95% CI 0.06 to 2.27) cm, p=0.04) at 12 weeks. No other between-group differences were detected. Per capita programme delivery (NZD1130/GBP573 vs NZD3466/GBP1758) and medication costs (NZD331/GBP168 vs NZD605/GBP307, p=0.02) were lower for REMOTE-CR. Hospital service utilisation costs were not statistically significantly different (NZD3459/GBP1754 vs NZD5464/GBP2771, p=0.20)., Conclusion: REMOTE-CR is an effective, cost-efficient alternative delivery model that could-as a complement to existing services-improve overall utilisation rates by increasing reach and satisfying unique participant preferences., Competing Interests: Competing interests: RM was supported by the New Zealand Health Research Council (Sir Charles Hercus health research fellowship).

Background: Aerobic exercise, which has been shown to have beneficial effects on plasma lipids, has been recommended as an effective measure to improve the prognosis of individuals with coronary heart disease (CHD). Apolipoprotein C3 (apoC3) is associated with hypertriglyceridemia and is therefore closely related to CHD., Hypothesis: We measured apoC3 concentration change in patients with CHD before and after long-term aerobic exercise., Methods: Thirty-eight patients with coronary heart disease were randomly assigned to a non-exercise group (19 patients) or exercise group (19 patients). Both groups received essential drugs for CHD. The non-exercise group was kept sedentary while the exercise group performed moderate-intensive aerobic exercise for 8 weeks. Lipid levels and apoC3 levels were measured on the first day and 8 weeks later., Results: Exercise for 8 weeks led to a significant decrease in concentration of triglyceride and apoC3 compared with the baseline. Triglyceride concentration changes were positively associated with apoC3 level changes., Conclusions: Aerobic exercise can improve the lipid profile. It is effective in decreasing triglycerides by targeting apoC3 levels in patients with coronary heart disease., (© 2018 Wiley Periodicals, Inc.)

Traditional, facility-based cardiac rehabilitation (CR) is vastly underutilized in the United States. The Veterans Health Administration (VA) has developed new home-based cardiac rehabilitation (HBCR) programs to address this issue. However, the characteristics of patients who choose HBCR are unknown. We sought to determine predictors of participation and completion of HBCR at the San Francisco VA (SFVA). We evaluated patients hospitalized for ischemic heart disease between 2013 and 2016 at SFVA. Logistic regression models were used to identify predictors of participation and completion of HBCR. In 724 patients with ischemic heart disease who were eligible for CR between 2013 and 2016, 314 (43%) enrolled in HBCR. Older age was associated with lower odds of participation in HBCR (odds ratio [OR] 0.84; p <0.01). Additionally, patients with coronary artery bypass grafting (CABG) were twice as likely as those with percutaneous coronary intervention to participate in HBCR (OR 2.03; 95% confidence interval 1.40, 2.97). In HBCR participants, 48% (150/314) completed ≥9 sessions. Patients with CABG were twice as likely as those with percutaneous coronary intervention to complete the HBCR program (OR 2.02; 95% confidence interval 1.18, 3.44). There were no differences in participation or completion rates by gender, race, ethnicity, or rurality. Our study showed that the SFVAMC HCBR program achieved a 43% participation rate, well above the VA average of 13%. There were no disparities by gender, race, or rurality in terms of participation and adherence. CABG as the indication for CR was the most significant predictor of participation and completion of HBCR., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Although evidence exists for the efficacy of cardiac rehabilitation programmes to reduce morbidity and mortality among patients with cardiovascular disease, cardiac rehabilitation programmes are underused. We aimed systematically to review the evidence from prospective cohort studies on factors associated with non-participation in and/or dropping out from cardiac rehabilitation programmes., Methods: MedLine, Embase, Scopus, Open Grey and Cochrane Database were searched for relevant publications from inception to February 2018. Search terms included (a) coronary heart disease and other cardiac conditions; (b) cardiac rehabilitation and secondary prevention; and (c) non-participation in and/or dropout. Databases were searched following the PRISMA statement. Study selection, data extraction and the assessment of study quality were performed in duplicate., Results: We selected 43 studies with a total of 63,425 patients from 10 different countries that met the inclusion criteria. Factors associated with non-participation in and dropout from cardiac rehabilitation were grouped into six broad categories: intrapersonal factors, clinical factors, interpersonal factors, logistical factors, cardiac rehabilitation programme factors and health system factors. We found that clinical factors, logistical factors and health system factors were the main factors assessed for non-participation in cardiac rehabilitation. We also found differences between the factors associated with non-participation and dropout., Conclusions: Several factors were determinant for non-participation in and dropout from cardiac rehabilitation. These findings could be useful to clinicians and policymakers for developing interventions aimed at improving participation and completion of cardiac rehabilitation, such as E-health or home-based delivery programmes.

Background: Exercise-based cardiac rehabilitation (CR) has been recognized as an essential component of the treatment for coronary heart disease (CHD). Determining the efficacy of modern alternative treatment methods is the key to developing exercise-based CR programs., Methods: Studies published through June 6, 2016, were identified using MEDLINE, EMBASE, and the Cochrane Library. English-language articles regarding the efficacy of different modes of CR in patients with CHD were included in this analysis. Two investigators independently reviewed abstracts and full-text articles and extracted data from the studies. According to the categories described by prior Cochrane reviews, exercise-based CR was classified into center-based CR, home-based CR, tele-based CR, and combined CR for this analysis. Outcomes included all-cause mortality, cardiovascular death, recurrent fatal and/or nonfatal myocardial infarction, recurrent cardiac artery bypass grafting, recurrent percutaneous coronary intervention (PCI), and hospital readmissions., Results: Sixty randomized clinical trials (n = 19,411) were included in the analysis. Network meta-analysis (NMA) demonstrated that only center-based CR significantly reduced all-cause mortality (center-based: RR = 0.76 [95% CI 0.64-0.90], p = 0.002) compared to usual care. Other modes of CR were not significantly different from usual care with regard to their ability to reduce mortality. Treatment ranking indicated that combined CR exhibited the highest probability (86.9%) of being the most effective mode, but this finding was not statistically significant due to the small sample size (combined: RR = 0.50 [95% CI 0.20-1.27], p = 0.146)., Conclusions: Current evidence suggests that center-based CR is acceptable for patients with CHD. As home- and tele-based CR can save time, money, effort, and resources and may be preferred by patients, their efficacy should be investigated further in subsequent studies.

Background: Web-based and theory-based interventions for multiple health behaviors appears to be a promising approach with respect to the adoption and maintenance of a healthy lifestyle in cardiac patients who have been discharged from the hospital. Until now, no randomized controlled trials have tested this assumption among Chinese rehabilitation patients with coronary heart disease using a Web-based intervention., Objective: The study aim was to evaluate the effect of an 8-week Web-based intervention in terms of physical activity (PA), fruit and vegetable consumption (FVC), lifestyle changes, social-cognitive outcomes, and health outcomes compared with a waiting control group in Chinese cardiac patients. The intervention content was theory-based on the health action process approach. Self-reported data were evaluated, including PA, FVC, healthy lifestyle (the synthesis of PA and FVC), internal resources (combination of intention, self-efficacy, and planning), and an external resource (social support) of PA and FVC behaviors, as well as perceived health outcomes (body mass index, quality of life, and depression)., Methods: In a randomized controlled trial, 136 outpatients with coronary heart disease from the cardiac rehabilitation center of a hospital in China were recruited. After randomization and exclusion of unsuitable participants, 114 patients were assigned to 1 of the 2 groups: (1) the intervention group: first 4 weeks on PA and subsequent 4 weeks on FVC and (2) the waiting control group. A total of 2 Web-based assessments were conducted, including 1 at the beginning of the intervention (T1, N=114), and 1 at the end of the 8-week intervention (T2, N=83). The enrollment and follow-up took place from December 2015 to May 2016., Results: The Web-based intervention outperformed the control condition for PA, FVC, internal resources of PA and FVC, and an external resource of FVC, with an eta-squared effect size ranging from 0.06 to 0.43. Furthermore, the intervention effect was seen in the improvement of quality of life (F 1,79 =16.36, P<.001, η 2 =.17). When predicting a healthy lifestyle at follow-up, baseline lifestyle (odds ratio, OR 145.60, 95% CI 11.24-1886; P<.001) and the intervention (OR 21.32, 95% CI 2.40-189.20; P=.006) were found to be significant predictors. Internal resources for FVC mediated the effect of the intervention on the adoption of a healthy lifestyle (R 2 adj =.29; P=.001), indicating that if the intervention increased the internal resource of behavior, the adoption of a healthy lifestyle was more likely., Conclusions: Patients' psychological resources such as motivation, self-efficacy, planning, and social support as well as lifestyle can be improved by a Web-based intervention that focuses on both PA and FVC. Such an intervention enriches extended rehabilitation approaches for cardiac patients to be active and remain healthy in daily life after hospital discharge., Trial Registration: ClinicalTrials.gov NCT01909349; https://clinicaltrials.gov/ct2/show/NCT01909349 (Archived by WebCite at http://www.webcitation.org/6pHV1A0G1)., (©Yan Ping Duan, Wei Liang, Lan Guo, Julian Wienert, Gang Yan Si, Sonia Lippke.

Objective: Evaluate user experiences of an exercise-based cardiac telerehabilitation intervention (REMOTE-CR) that provided near universal access to real-time remote coaching and behavioral support from exercise specialists., Design: Secondary analysis (12-week follow-up) of a parallel group, single blind, randomized controlled noninferiority trial (ACTRN12614000843651)., Setting: Community-based cardiac rehabilitation., Participants: Adults (N=162) with coronary heart disease who were eligible for outpatient cardiac rehabilitation. Eighty-two of 162 trial participants were randomized to receive REMOTE-CR; 67 completed usability and acceptability assessment at 12-week follow-up., Intervention: REMOTE-CR comprised 12 weeks of individualized exercise prescription, real-time physiological monitoring, coaching, and behavioral support, delivered via a bespoke telerehabilitation platform., Outcomes: Ease of use, satisfaction with the technology platform and intervention content, and demand for real-world implementation as an alternative to traditional center-based programs were assessed at 12-week follow-up., Results: Components of usability and acceptability were positively evaluated by most participants (44-66 of 67, 66%-99%). Fifty-eight of 67 (87%) would choose REMOTE-CR if it was available as a usual care service, primarily because it provides convenient and flexible access to real-time individualized support from exercise specialists. Technology challenges were rare and had little effect on user experiences or demand for REMOTE-CR., Conclusions: REMOTE-CR can extend the reach and impact of existing cardiac rehabilitation services by overcoming traditional participation barriers while preserving expert oversight. Adoption of emerging technologies should be accelerated to support dynamic, engaging, individualized intervention delivery models, but optimizing overall cardiac rehabilitation participation rates will require multiple delivery models that are tailored to satisfy diverse participant preferences., (Copyright © 2018 American Congress of Rehabilitation Medicine.

Cardiac rehabilitation (CR) is recommended for patients with coronary heart disease, however, participation among veterans remains poor. Smartphones may facilitate data transfer and communication between patients and providers, among other benefits. We evaluated the feasibility of a smartphone-enabled CR program in a population of veterans. Qualifying veterans were prospectively enrolled in a single-arm, nonrandomized feasibility study of a smartphone-enabled, home-based CR program, featuring an app with daily reminders to exercise, log vitals, and review educational materials. A coach remotely monitored patients through an online dashboard and scheduled telephone visits. Clinical end points were assessed as an exploratory aim. After 21 veterans provided informed consent, 18 were enrolled and successfully completed at least 30days of the program; 13 completed the entire 12-week intervention. Mean (standard deviation) age was 62 (7) years and 96% were male. Program completers logged a mean (standard deviation) of 3.5 (1.4) exercise sessions and 150 (86) exercise minutes per week. The majority (84%) of program completers reported being satisfied overall with the program. Mean functional capacity improved by 1.0 metabolic equivalents (5.3 to 6.3, 95% confidence interval 0.3 to 1.7; p = 0.008) and mean systolic blood pressure at rest improved by 9.6mm Hg (mean difference 9.6, 95% confidence interval -19.0 to -0.7; p = 0.049) among completers. Smartphone-enabled, home-based CR is feasible in veterans with heart disease and is associated with moderate to high levels of engagement and patient satisfaction., (Copyright © 2018.

Purpose of Review: To review recent literature on associations between habitual physical activity and mortality in general populations and patients with stable coronary heart disease., Recent Findings: There are substantial decreases in cardiovascular and all-cause mortality between people who take little or no exercise and those who take regular light or moderate physical activity. The benefits associated with increasing high-intensity exercise are smaller, and an increase in mortality risk is possible. Meta-analyses of trials of exercise-based cardiac rehabilitation suggest a small mortality benefit from supervised exercise training, but because of a high risk of bias, the impact on cardiovascular mortality and hospitalizations is uncertain., Summary: Modest habitual physical activity is likely to lower mortality in most patients with stable coronary heart disease.

Aim: To examine the effect of a self-help psychoeducation program for people with coronary heart disease in Singapore., Background: Cardiac rehabilitation has shown benefits for mitigating many cardiac risk factors and can lead to improvement in health-related quality of life and psychological well-being in people with heart disease. However, traditional hospital-based cardiac rehabilitation faces substantial challenges. A self-management cardiac rehabilitation program offers an avenue to increase uptake and empowers patients to manage their condition at home., Design: A two-arm, randomized controlled trial., Methods: A total of 129 patients with coronary heart disease were recruited from an outpatient clinic in a public hospital in Singapore from April 2015-January 2016. They were randomly assigned to the intervention group or the control group. Participants in the intervention group received the 4-week home-based self-help psychoeducation program. Outcomes were measured at baseline and at 4 weeks and 16 weeks from the baseline., Results: There were no significant differences in health-related quality of life, psychological status (i.e., perceived stress level, anxiety, and depression levels), or cardiac physiological risk parameters between the intervention and the control groups immediately after the program or at different time points. There was also no significant difference in unplanned health service use at the 16 week posttest point between the two groups., Conclusions: This study did not find any significant effect of our program on outpatients with coronary heart disease. Nonetheless, findings on participant characteristics may offer healthcare professionals valuable insights to help facilitate future development of an effective cardiac rehabilitation program catered to outpatients with coronary heart disease., Trial Registration: The study has been registered with ISRCTN registry. The trial registration number is ISRCTN15839687., (© 2018 John Wiley & Sons Ltd.)
