Aims The clinical outcome of heart failure (HF) is complicated by the presence of multiple comorbidities including malnutrition and cachexia, and prediction of the outcome is still difficult in each patient. Metabolomics including amino acid profiling enables detection of alterations in whole body metabolism. The aim of this study was to determine whether plasma amino acid profiling improves prediction of clinical outcomes in patients with HF. Methods and results We retrospectively examined 301 HF patients (70 ± 15 years old; 59% male). Blood samples for measurements of amino acid concentrations were collected in a fasting state after stabilization of HF. Plasma amino acid concentrations were measured using ultraperformance liquid chromatography. Clinical endpoint of this study was adverse event defined as all‐cause death and unscheduled readmission due to worsening HF or lethal arrhythmia. During a mean follow‐up period of 380 ± 214 days, 40 patients (13%) had adverse events. Results of analyses of variable importance in projection score, a measure of a variable's importance in partial least squares–discriminant analysis (PLS‐DA) showed that the top five amino acids being associated with adverse events were 3‐methylhistidine (3‐Me‐His), β‐alanine, valine, hydroxyproline, and tryptophan. Multivariate Cox‐proportional hazard analyses indicated that a high 3‐Me‐His concentration and low β‐alanine and valine concentrations were independently associated with adverse events. When HF patients were divided according to the cut‐off values of amino acids calculated from receiver operating characteristic curves, Kaplan–Meier survival curves showed that event‐free survival rates were lower in HF patients with high 3‐Me‐His than in HF patients with low 3‐Me‐His (68% vs. 91%, P

©The European Society of Cardiology 2020. Article reuse guidelines : sagepub.com/journals-permissions, Secondary prevention through comprehensive cardiac rehabilitation has been recognized as the most cost-effective intervention to ensure favourable outcomes across a wide spectrum of cardiovascular disease, reducing cardiovascular mortality, morbidity and disability, and to increase quality of life. The delivery of a comprehensive and ‘modern’ cardiac rehabilitation programme is mandatory both in the residential and the out-patient setting to ensure expected outcomes. The present position paper aims to update the practical recommendations on the core components and goals of cardiac rehabilitation intervention in different cardiovascular conditions, in order to assist the whole cardiac rehabilitation staff in the design and development of the programmes, and to support healthcare providers, insurers, policy makers and patients in the recognition of the positive nature of cardiac rehabilitation. Starting from the previous position paper published in 2010, this updated document maintains a disease-oriented approach, presenting both well-established and more controversial aspects. Particularly for implementation of the exercise programme, advances in different training modalities were added and new challenging populations were considered. A general table applicable to all cardiovascular conditions and specific tables for each clinical condition have been created for routine practice.

Aim Clinical evidence on cardiovascular health metrics of couples, as defined by the American Heart Association (AHA), remains to be scarce. This study aims to explore the correlation of the AHA-defined cardiovascular health metrics within couples using a nationwide epidemiological database. Methods We examined the modified cardiovascular health metrics among 87,160 heterosexual couples using the health claims database from the Japan Medical Data Center. The ideal cardiovascular health metrics is comprised of (1) nonsmoking, (2) body mass index ＜25 kg/m2, (3) physical activity at goal, (4) untreated blood pressure ＜120/80 mm Hg, (5) untreated fasting glucose ＜100 mg/dL, and (6) untreated total cholesterol ＜200 mg/dL. Results A correlation was noted on the ideal modified cardiovascular health metrics between couples. The prevalence of meeting ≥ 5 ideal components in the female partners increased from 32 % in the male partners meeting 0-1 ideal component to 56 % in those meeting 6 ideal components. The same trend has been observed in all generations (20-39 years, 40-49 years, 50-59 years, ≥ 60 years). The association between couples is found to be better in terms of smoking status, blood pressure, and fasting glucose level. Conclusion There was an intracouple correlation of the ideal modified cardiovascular health metrics, suggesting the importance of couple-based intervention to improve cardiovascular health status.

Background and aims Heart rate variability (HRV) is a main determinant of autonomic function and related to the development of hypertension and cardiovascular (CV) disease. Hypertension develops in black populations at an earlier age, which could be due to differences in the autonomic nervous system activity and sodium/potassium handling in black and white populations. We investigated whether HRV is associated with 24 h urinary sodium and potassium excretion and blood pressure (BP) in a young bi-ethnic cohort. Methods and results We examined 423 black and 483 white healthy adults (aged 24.5 ± 3.1 years) for 24 h HRV, including standard deviation of normal RR intervals (SDNN) reflecting autonomic variations over time, and root mean square of successive differences (RMSSD) reflecting parasympathetic activity. We measured 24 h urinary sodium and potassium concentration and BP. The black group had lower SDNN and potassium excretion as well as higher RMSSD, sodium and Na/k ratio compared to the white group (all p Conclusion Lower potassium excretion and higher Na/K ratio related independently to higher HRV in young and healthy black adults. A better ethnic-specific understanding of sodium and potassium handling is required as part of preventive cardiology, especially in black individuals.

Introduction . Tobacco smoking is one of the main and independent risk factors for cardiovascular disease developing. Despite the fact that the main effects of tobacco use on human health are well known, the annual number of smokers on the planet is still growing. The aim of the study was to study the twenty-year dynamics of the prevalence of tobacco smoking among women aged 25–64 in the open population of a moderately urbanized city of Western Siberia. Material and methods . Within the regional program for monitoring the epidemiological situation in relation to the risk of developing CVD in 1996 and 2016. Two simultaneous epidemiological studies were carried out among persons from the Central Administrative District of Tyumen – a sample of 1000 women aged 25–64 years. The yield was 81.3 % ( n = 813) in 1996, and 70.3 % ( n = 703) in 2010. The prevalence of tobacco smoking was determined using a questionnaire developed in the former USSR by the Institute of Preventive Cardiology of the Academy of Medical Sciences (now FSBI «NIMTs TPM» of the Ministry of Health of Russia) as part of the implementation of the Cooperative Study on Multifactorial Prevention of cardiac ischemia. Results and its discussion . According to the results of 20-year monitoring among women aged 25–64 years of the open population of a medium-urbanized city of Western Siberia, an increase in the prevalence of tobacco smoking was established (23.1 % – 31.2 %, p = 0.0036). The highest prevalence of tobacco smoking was found in women in the third decade of life, a significant increase in the indicator during the 20-year monitoring of the open population - in the fourth to sixth decades of life. The established patterns in the dynamics of the increase in the prevalence of tobacco smoking among women aged 25–64 years in the open population of a mediumurbanized city of Western Siberia were determined by an increase in the proportion of women who smoke irregularly (11.4 % – 20.1 %, p = 0.0000) and who started smoking (27.7 % – 37.6 %, p = 0,0000). 20-year monitoring of the open population of a medium-urbanized city of Western Siberia showed some positive trends in the decrease in regular tobacco smoking among women in the third decade of life (25.1 % – 13.5 %, p = 0.0187). Conclusion . Thus, in the open population of a moderately urbanized city of Western Siberia over the period of 20-year monitoring among women aged 25–64 years, a negative epidemiological situation was established in terms of the dynamics of the prevalence of tobacco smoking due to the growth of irregular tobacco smoking and those who started smoking. Positive trends in the Tyumen population are determined by a decrease in the prevalence of regular tobacco smoking in one age group of 25–34 years.

In Uzbekistan, despite the undoubted achievements in the field of preventive cardiology, there is a need and demand in the elderly and senile population to optimize the known methods of drug primary and secondary prevention, taking into account the epidemiological characteristics of regional risk factors for myocardial infarction.A high percentage of the prevalence of the main risk factors and their with AMI is a favorable prerequisite for the implementation of treatment and prophylactic programs in the elderly and senile population.

Aspirin’s antithrombotic effects have a long-established place in the prevention of cardiovascular disease (CVD), and its traditional use as a core therapy for secondary prevention of CVD is well recognized. However, with the advent of newer antiplatelet agents and an increasing understanding of aspirin’s bleeding risks, its role across the full spectrum of modern CVD prevention has become less certain. As a consequence, recent trials have begun investigating aspirin-free strategies in secondary prevention. For example, a contemporary metanalysis of trials that assessed P2Y12 inhibitor monotherapy versus prolonged (≥ 12 months) dual antiplatelet therapy (which includes aspirin) after percutaneous coronary intervention reported a lower risk of major bleeding and no increase in stent thrombosis, all-cause mortality, myocardial infarction (MI), or stroke in the P2Y12 monotherapy group. In contrast to secondary prevention, aspirin’s role in primary prevention has always been more controversial. While historical trials reported a reduction in MI and stroke, more contemporary trials have suggested diminishing benefit for aspirin in this setting, with no reduction in hard outcomes, and some primary prevention trials have even indicated a potential for harm. In this review, we discuss how changing population demographics, enhanced control of lipids and blood pressure, changes in the definition of outcomes like MI, evolution of aspirin formulations, and updated clinical practice guidelines have all impacted the use of aspirin for primary and secondary CVD prevention.

Hospital administrations and providers are more than ever in need for new technologies and innovative methods with clinical benefit at lower costs. Surgeons and clinicians depend on conventional risk stratification scores developed to allow physicians to establish the risk of perioperative mortality. However, the current practiced models of preventive cardiology largely depend on patient motivation and awareness to be able to apply such risk scores appropriately. It was not until the appearance of miniaturized pocket-sized, user-friendly digital technologies that the awareness started to grow, highlighting the importance of role of technology and artificial intelligence in modern-day medicine.

The article focuses on scientific disagreement about the use of statin-related drugs in the prevention of cardiovascular events. The study forms part of an exploration of the broader principle of research polarization, foremost in medicine. The hypothesis is that statin-positive and statin-critical researchers publish in different committed central journals, and that they are financially supported by different dedicated corporate sources. Methodologically we use Web of Science (WoS) analytic tools to perform publication analysis of a time series covering 1998–2018 in three seven-year windows. For each window data is captured based on sets of known statin-positive and statin-critical articles and researchers, and their primary and secondary co-authors. Standard deviation is used as a focused normalization and visual instrument together with Spearman’s correlation coefficient in order to compare frequency distributions of statin-positive and critical journal and sponsor articles. Z-test p-values are used to assess the probability of error concerning the distributions. Findings at general topical level showed that a few journals consistently and significantly occupied top positions, 2 of which, American Journal of Cardiology and Circulation, published articles from both positions. Besides, Journal of the American College of Cardiology served as a major publisher of statin-positive research from 2005, as did European Heart Journal from 2012, replacing American Journal of Cardiology at the top. From 2012 Atherosclerosis and European Journal of Preventive Cardiology served as top-publishers of statin-critical articles. Two central US funding agencies, US Department of Health Human Services and National Institutes of Health (NIH), operated at general topical level across the time series, but the agencies played only a minor role in the divergent research positions. From 2005 statin-positive as well as statin-critical research was mainly sponsored by multinational pharmaceutical companies, predominantly Merck, AstraZeneca and Pfizer. In conclusion, the initial hypothesis about dedicated journals and sponsors was entirely substantiated at the general topical level and at the journal level of research disagreement, but not at sponsor level. Distinct dedicated journals were extracted separately from the 2 divergent statin positions. Since the WoS coverage of sponsor data 1998–2004 was sporadic sponsor data are analyzed from 2005. Only from 2012 the WoS sponsor coverage of the topic is consistently at 60%.

Electronic cigarettes and health with special focus on cardiovascular effects: position paper of the European Association of Preventive Cardiology (EAPC). European Journal of Preventive Cardiology (EJPC). 2020:2047487320941993, is available online at: https://doi.org/10.1177/2047487320941993. Background - Tobacco use is the single largest preventable risk factor for premature death of non-communicable diseases and the second leading cause of cardiovascular disease. In response to the harmful effects of tobacco smoking, the use of electronic cigarettes (e-cigarettes) has emerged and gained significant popularity over the past 15 years. E-cigarettes are promoted as safe alternatives for traditional tobacco smoking and are often suggested as a way to reduce or quit smoking. However, evidence suggests they are not harmless. Discussion - The rapid evolution of the e-cigarette market has outpaced the legislator’s regulatory capacity, leading to mixed regulations. The increasing use of e-cigarettes in adolescents and young individuals is of concern. While the long-term direct cardiovascular effects of e-cigarettes remain largely unknown, the existing evidence suggests that the e-cigarette should not be regarded as a cardiovascular safe product. The contribution of e-cigarette use to reducing conventional cigarette use and smoking cessation is complex, and the impact of e-cigarette use on long-term cessation lacks sufficient evidence. Conclusion - This position paper describes the evidence regarding the prevalence of e-cigarette smoking, uptake of e-cigarettes in the young, related legislations, cardiovascular effects of e-cigarettes and the impact of e-cigarettes on smoking cessation. Knowledge gaps in the field are also highlighted. The recommendations from the population science and public health section of the European Association of Preventive Cardiology are presented.

Background Cardiovascular disease (CVD) is the primary cause of death in the developed‐countries and mostly in the poorer areas of the country, and in lower income‐groups. Hypothesis Birthweight predicts adult development of angina, coronary heart disease, stroke, and combination of all CVD. Methods The AusDiab is a cross‐sectional study of Australians aged 25 years or over. Data on age, sex, previous‐CVD, smoking‐status, alcohol‐intake, time‐spent on watching television and physical‐activity, total house‐income, dwelling‐type and education‐level were collected by interviewer‐ administered‐questionnaires. Results Four thousand five hundred and two had birthweights (mean (SD) of 3.4(0.7) kg). Females in the lowest birthweight‐quintile were at least 1.23, 1.48, 1.65, and 1.23 times more likely to have angina, CAD, stroke, and CVS compared to the referent group ≥3.72 kg with P = .123, .09, .099, and 0.176, respectively. Similarly, males in the lowest‐birthweight‐quintile were 1.23, 1.30, 1.39, and 1.26 times more likely to have angina, CAD, stroke, and CVS compared to the referent‐group ≥4.05 kg with P = .231, .087, .102, and .123, respectively. Females with low birth weight (LBW) were at least 1.39, 1.40, 2.30, and 1.47 times more likely to have angina, CAD, stroke and CVS compared to those ≥2.5 kg with P = .06, .19, .03, and .13, respectively. Similarly, males with LBW were 1.76, 1.48, 3.34, and 1.70 times more likely to have angina, CAD, stroke, and CVS compared to those ≥2.5 kg with P = .14, .13, .03, and .08, respectively. Conclusion there was a negative relationship between birth weight and angina, CAD, stroke, and the overall CVS. It would be prudent, to adopt policies of intensified whole of life surveillance of lower‐birthweight people, anticipating this risk.

Aggressive risk factor modification, including smoking cessation, blood pressure management, and more intensive efforts to control hyperlipidemia, as well as stress management training, are associated with improved cardiovascular outcomes and impressive mortality reductions. This commentary addresses these topics, with specific reference to lifestyle modification and complementary cardioprotective medications.

The health benefit of fish oil, i.e. omega-3 fatty acids (ω-3 FA) has a long history of debate. While there are a number of medications to reduce serum triglyceride levels, none have shown unanimous cardiovascular (CV) benefits. The most recent Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) assessing the CV outcome of one highly purified prescription ω-3 FA has certainly rejuvenated the debate. While this trial has been regarded as one of the most important landmark trials in preventive cardiology, the tolerability issue in a very high dose (4 g/day, as administered in the trial) is still a matter of concern. This article summarizes the current status and future perspective of icosapent ethyl in clinical practice in light of REDUCE-IT.

Aims To develop a set of quality indicators (QIs) for the evaluation of the care and outcomes for atherosclerotic cardiovascular disease (ASCVD) prevention. Methods and results The Quality Indicator Committee of the European Society of Cardiology (ESC) formed the Working Group for Cardiovascular Disease Prevention Quality Indicators in collaboration with Task Force members of the 2021 ESC Guidelines on Cardiovascular Disease Prevention in Clinical Practice and the European Association of Preventive Cardiology (EAPC). We followed the ESC methodology for QI development, which involved (i) the identification of the key domains of care for ASCVD prevention by constructing a conceptual framework of care, (ii) the development of candidate QIs by conducting a systematic review of the literature, (iii) the selection of the final set of QIs using a modified Delphi method, and (iv) the evaluation of the feasibility of the developed QIs. In total, 17 main and 14 secondary QIs were selected across six domains of care for ASCVD prevention: (i) structural framework, (ii) risk assessment, (iii) care for people at risk for ASCVD, (iv) care for patients with established ASCVD, (v) patient education and experience, and (vi) outcomes. Conclusion We present the 2021 ESC QIs for Cardiovascular Disease Prevention, which have been co-constructed with EAPC using the ESC methodology for QI development. These indicators are supported by evidence from the literature, underpinned by expert consensus and aligned with the 2021 ESC Guidelines on Cardiovascular Disease Prevention in Clinical Practice to offer a mechanism for the evaluation of ASCVD prevention care and outcomes.

Background Cardiomyopathy is a common cause of atrial fibrillation (AF) and may also present as a complication of AF. However, there is a scarcity of evidence of clinical outcomes for people with cardiomyopathy and concomittant AF. The aim of the present study was therefore to characterize the prevalence of AF in major subtypes of cardiomyopathy and investigate the impact on important clinical outcomes. Methods and Results A retrospective cohort study was conducted using electronic medical records from a global federated health research network, with data primarily from the United States. The TriNetX network was searched on January 17, 2021, including records from 2002 to 2020, which included at least 1 year of follow‐up data. Patients were included based on a diagnosis of hypertrophic, dilated, or restrictive cardiomyopathy and concomitant AF. Patients with cardiomyopathy and AF were propensity‐score matched for age, sex, race, and comorbidities with patients who had a cardiomyopathy only. The outcomes were 1‐year mortality, hospitalization, incident heart failure, and incident stroke. Of 634 885 patients with cardiomyopathy, there were 14 675 (2.3%) patients with hypertrophic, 90 117 (7.0%) with restrictive, and 37 685 (5.9%) with dilated cardiomyopathy with concomitant AF. AF was associated with significantly higher odds of all‐cause mortality (odds ratio [95% CI]) for patients with hypertrophic (1.26 [1.13–1.40]) and dilated (1.36 [1.27–1.46]), but not restrictive (0.98 [0.94–1.02]), cardiomyopathy. Odds of hospitalization, incident heart failure, and incident stroke were significantly higher in all cardiomyopathy subtypes with concomitant AF. Among patients with AF, catheter ablation was associated with significantly lower odds of all‐cause mortality at 12 months across all cardiomyopathy subtypes. Conclusions Findings of the present study suggest AF may be highly prevalent in patients with cardiomyopathy and associated with worsened prognosis. Subsequent research is needed to determine the usefulness of screening and multisdisciplinary treatment of AF in this population.

Background Trimethylamine‐ N ‐oxide (TMAO) is a small molecule derived from the metabolism of dietary nutrients by gut microbes and contributes to cardiovascular disease. Plasma TMAO increases following consumption of red meat. This metabolic change is thought to be partly because of the expansion of gut microbes able to use nutrients abundant in red meat. Methods and Results We used data from a randomized crossover study to estimate the degree to which TMAO can be estimated from fecal microbial composition. Healthy participants received a series of 3 diets that differed in protein source (red meat, white meat, and non‐meat), and fecal, plasma, and urine samples were collected following 4 weeks of exposure to each diet. TMAO was quantitated in plasma and urine, while shotgun metagenomic sequencing was performed on fecal DNA. While the cai gene cluster was weakly correlated with plasma TMAO (rho=0.17, P =0.0007), elastic net models of TMAO were not improved by abundances of bacterial genes known to contribute to TMAO synthesis. A global analysis of all taxonomic groups, genes, and gene families found no meaningful predictors of TMAO. We postulated that abundances of known genes related to TMAO production do not predict bacterial metabolism, and we measured choline‐ and carnitine‐trimethylamine lyase activity during fecal culture. Trimethylamine lyase genes were only weakly correlated with the activity of the enzymes they encode. Conclusions Fecal microbiome composition does not predict systemic TMAO because, in this case, gene copy number does not predict bacterial metabolic activity.

Background Coronary artery calcium (CAC) is well‐validated for cardiovascular disease risk stratification in middle to older–aged adults; however, the 2019 American College of Cardiology/American Heart Association guidelines state that more data are needed regarding the performance of CAC in low‐risk younger adults. Methods and Results We measured CAC in 13 397 patients aged 30 to 49 years without known cardiovascular disease or malignancy between 1997 and 2009. Outcomes of myocardial infarction (MI), stroke, major adverse cardiovascular events (MACE; MI, stroke, or cardiovascular death), and all‐cause mortality were assessed using Cox proportional hazard models, controlling for baseline risk factors (including atrial fibrillation for stroke and MACE) and the competing risk of death or noncardiac death as appropriate. The cohort (74% men, mean age 44 years, and 76% with ≤1 cardiovascular disease risk factor) had a 20.6% prevalence of any CAC. CAC was independently predicted by age, male sex, White race, and cardiovascular disease risk factors. Over a mean of 11 years of follow‐up, the relative adjusted subhazard ratio of CAC >0 was 2.9 for MI and 1.6 for MACE. CAC >100 was associated with significantly increased hazards of MI (adjusted subhazard ratio, 5.2), MACE (adjusted subhazard ratio, 3.1), stroke (adjusted subhazard ratio, 1.7), and all‐cause mortality (hazard ratio, 2.1). CAC significantly improved the prognostic accuracy of risk factors for MACE, MI, and all‐cause mortality by the likelihood ratio test ( P Conclusions CAC was prevalent in a large sample of low‐risk young adults. Those with any CAC had significantly higher long‐term hazards of MACE and MI, while severe CAC increased hazards for all outcomes including death. CAC may have utility for clinical decision‐making among select young adults.

Background There is wide variability in cardiac rehabilitation (CR) dose (ie, number of sessions) delivered, and no evidence‐based recommendations regarding what dose to prescribe. We aimed to test what CR dose impacts major adverse cardiovascular events (MACEs). Methods and Results This is an historical cohort study of all patients who had coronary artery disease and who initiated supervised CR between 2002 and 2012 from a single major CR center. CR dose was defined as number of visits including exercise and patient education. Follow‐up was performed using record linkage from the Rochester Epidemiology Project. MACEs included acute myocardial infarction, unstable angina, ventricular arrhythmias, stroke, revascularization, or all‐cause mortality. Dose was analyzed in several ways, including tertiles, categories, and as a continuous variable. Cox models were adjusted for factors associated with dose and MACE. The cohort consisted of 2345 patients, who attended a mean of 12.5±11.1 of 36 prescribed sessions. After a mean follow‐up of 6 years, 695 (29.65%) patients had a MACE, including 231 who died. CR dose was inversely associated with MACE (hazard ratio, 0.66 [95% CI]; 0.55–0.91) in those completing ≥20 sessions, when compared with those not exposed to formal exercise sessions (≤1 session; log‐rank P =0.007). We did not find evidence of nonlinearity ( P ≥0.050), suggesting no minimal threshold nor ceiling. Each additional session was associated with a lower rate of MACE (fully adjusted hazard ratio, 0.98 [95% CI, 0.97–0.99]). Greater session frequency was also associated with lower MACE risk (fully adjusted hazard ratio, 0.74 [95% CI, 0.58–0.94]). Conclusions CR reduces MACEs, but the benefit appears to be linear, with greater risk reduction with higher doses, and no upper threshold.

Background Atrial fibrillation (AF) screening is endorsed by certain guidelines for individuals aged ≥65 years. Yet many AF screening strategies exist, including the use of wrist‐worn wearable devices, and their comparative effectiveness is not well‐understood. Methods and Results We developed a decision‐analytic model simulating 50 million individuals with an age, sex, and comorbidity profile matching the United States population aged ≥65 years (ie, with a guideline‐based AF screening indication). We modeled no screening, in addition to 45 distinct AF screening strategies (comprising different modalities and screening intervals), each initiated at a clinical encounter. The primary effectiveness measure was quality‐adjusted life‐years, with incident stroke and major bleeding as secondary measures. We defined continuous or nearly continuous modalities as those capable of monitoring beyond a single time‐point (eg, patch monitor), and discrete modalities as those capable of only instantaneous AF detection (eg, 12‐lead ECG). In total, 10 AF screening strategies were effective compared with no screening (300–1500 quality‐adjusted life‐years gained/100 000 individuals screened). Nine (90%) effective strategies involved use of a continuous or nearly continuous modality such as patch monitor or wrist‐worn wearable device, whereas 1 (10%) relied on discrete modalities alone. Effective strategies reduced stroke incidence (number needed to screen to prevent a stroke: 3087–4445) but increased major bleeding (number needed to screen to cause a major bleed: 1815–4049) and intracranial hemorrhage (number needed to screen to cause intracranial hemorrhage: 7693–16 950). The test specificity was a highly influential model parameter on screening effectiveness. Conclusions When modeled from a clinician‐directed perspective, the comparative effectiveness of population‐based AF screening varies substantially upon the specific strategy used. Future screening interventions and guidelines should consider the relative effectiveness of specific AF screening strategies.

Background Sleep variability and social jetlag are associated with adverse cardiometabolic outcomes via circadian disruption. Variable eating patterns also lead to circadian disruption, but associations with cardiometabolic health are unknown. Methods and Results Women (n=115, mean age: 33±12 years) completed a 1‐week food record using the Automated Self‐Administered 24‐Hour Dietary Assessment Tool at baseline and 1 year. Timing of first and last eating occasions, nightly fasting duration, and %kcal consumed after 5 pm (%kcal 5 pm ) and 8 pm (%kcal 8 pm ) were estimated. Day‐to‐day eating variability was assessed from the SD of these variables. Eating jetlag was defined as weekday‐weekend differences in these metrics. Multivariable‐adjusted linear models examined cross‐sectional and longitudinal associations of day‐to‐day variability and eating jetlag metrics with cardiometabolic risk. Greater jetlag in eating start time, nightly fasting duration, and %kcal 8 pm related to higher body mass index and waist circumference at baseline ( P pm SD predicted increased body mass index (β, 0.52; 95% CI, 0.23–0.81) and waist circumference (β, 1.73; 95% CI, 0.58–2.87); greater %kcal 8 pm weekday‐weekend differences predicted higher body mass index (β, 0.25; 95% CI, 0.07–0.43). Every 30‐minute increase in nightly fasting duration SD predicted increased diastolic blood pressure (β, 0.95; 95% CI, 0.40–1.50); an equivalent increase in nightly fasting duration weekday‐weekend differences predicted higher systolic blood pressure (β, 0.58; 95% CI, 0.11–1.05) and diastolic blood pressure (β, 0.45; 95% CI, 0.10–0.80). Per 10% increase in %kcal 5 pm SD, there were 2.98 mm Hg (95% CI, 0.04–5.92) and 2.37mm Hg (95% CI, 0.19–4.55) increases in systolic blood pressure and diastolic blood pressure; greater %kcal 5 pm weekday‐weekend differences predicted increased systolic blood pressure (β, 1.83; 95% CI, 0.30–3.36). For hemoglobin A1c, every 30‐minute increase in eating start and end time SD and 10% increase in %kcal 5 pm SD predicted 0.09% (95% CI, 0.03–0.15), 0.06% (95% CI, 0.001–0.12), and 0.23% (95% CI, 0.07–0.39) increases, respectively. Conclusions Variable eating patterns predicted increased blood pressure and adiposity and worse glycemic control. Findings warrant confirmation in population‐based cohorts and intervention studies.

Background Although severe hypercholesterolemia confers a 5‐fold increased long‐term risk for coronary artery disease, treatment guidelines may not be fully implemented, leading to underdiagnosis and suboptimal treatment. To further understand the clinical features and gaps in treatment approaches, we analyzed electronic medical record data from a midwestern US multidisciplinary healthcare system, between 2009 and 2020. Methods and Results We retrospectively assessed the prevalence, clinical presentation, and treatment characteristics of individuals currently treated with statin therapy having a low‐density lipoprotein cholesterol (LDL‐C) value that is either (1) an actual maximum electronic medical record–documented LDL‐C ≥190 mg/dL (group 1, n=7542) or (2) an estimated pretreatment LDL‐C ≥190 mg/dL (group 2, n=7710). Comorbidities and prescribed lipid‐lowering therapies were assessed. Statistical analyses identified differences among individuals within and between groups. Of records analyzed (n=266 282), 7% met the definition for primary severe hypercholesterolemia. Group 1 had more comorbidities than group 2. More individuals in both groups were treated by primary care providers (49.8%–53.0%, 32.6%–36.4%) than by specialty providers (4.1%–5.5%, 2.1%–3.3%). High‐intensity lipid‐lowering therapy was prescribed less frequently for group 2 than for group 1, but moderate‐intensity statins were prescribed more frequently for group 2 (65%) than for group 1 (52%). Conclusions Two percent of patients in our study population being treated with low‐ or moderate‐intensity statins have an estimated LDL‐C ≥190 mg/dL (indicating severe hypercholesterolemia), but receive less aggressive treatment than patients with a maximum measured LDL‐C ≥190 mg/dL.

Background Preeclampsia increases women's risks for maternal morbidity and future cardiovascular disease. The aim of this study was to identify opportunities for prevention by examining the association between cardiometabolic risk factors and preeclampsia across 2 pregnancies among women in a high‐risk US birth cohort. Methods and Results Our sample included 618 women in the Boston Birth Cohort with index and subsequent pregnancy data collected using standard protocols. We conducted log‐binomial univariate regression models to examine the association between preeclampsia in the subsequent pregnancy (defined as incident or recurrent preeclampsia) and cardiometabolic risk factors (ie, obesity, hypertension, diabetes mellitus, preterm birth, low birth weight, and gestational diabetes mellitus) diagnosed before and during the index pregnancy, and between index and subsequent pregnancies. At the subsequent pregnancy, 7% (36/540) had incident preeclampsia and 42% (33/78) had recurrent preeclampsia. Compared with women without obesity, women with obesity had greater risk of incident preeclampsia (unadjusted risk ratio [RR], 2.2 [95% CI, 1.1–4.5]) and recurrent preeclampsia (unadjusted RR, 3.1 [95% CI, 1.5–6.7]). Preindex pregnancy chronic hypertension and diabetes mellitus were associated with incident, but not recurrent, preeclampsia (hypertension unadjusted RR, 7.9 [95% CI, 4.1–15.3]; diabetes mellitus unadjusted RR, 5.2 [95% CI, 2.5–11.1]. Women with new interpregnancy hypertension versus those without had a higher risk of incident and recurrent preeclampsia (incident preeclampsia unadjusted RR, 6.1 [95% CI, 2.9–13]); recurrent preeclampsia unadjusted RR, 2.4 [95% CI, 1.5–3.9]). Conclusions In this diverse sample of high‐risk US women, we identified modifiable and treatable risk factors, including obesity and hypertension for the prevention of preeclampsia.

BackgroundCardiovascular disease is an important cause of mortality among survivors of breast cancer (BC). We developed a prediction model for major adverse cardiovascular events after BC therapy, which is based on conventional and BC treatment‐related cardiovascular risk factors.Methods and ResultsThe cohort of the study consisted of 1256 Asian female patients with BC from 4 medical centers in Korea and was randomized in a 1:1 ratio into the derivation and validation cohorts. The outcome measures comprised cardiovascular mortality, myocardial infarction, congestive heart failure, and transient ischemic attack/stroke. To correct overfitting, a penalized Cox proportional hazards regression was performed with a cross‐validation approach. Number of cardiovascular diseases (myocardial infarction, peripheral artery disease, heart failure, and transient ischemic attack/stroke), number of baseline cardiovascular risk factors (hypertension, age ≥60, body mass index ≥30 kg/m2, estimated glomerular filtration rate 2, dyslipidemia, and diabetes mellitus), radiation to the left breast, and anthracycline dose per 100 mg/m2were included in the risk prediction model. The time‐dependent C‐indices at 3 and 7 years after BC diagnosis were 0.876 and 0.842, respectively, in the validation cohort.ConclusionsA prediction score model, including BC treatment‐related risk factors and conventional risk factors, was developed and validated to predict major adverse cardiovascular events in patients with BC. The CHEMO‐RADIAT (congestive heart failure, hypertension, elderly, myocardial infarction/peripheral artery occlusive disease, obesity, renal failure, abnormal lipid profile, diabetes mellitus, irradiation of the left breast, anthracycline dose, and transient ischemic attack/stroke) score may provide overall cardiovascular risk stratification in survivors of BC and can assist physicians in multidisciplinary decision‐making regarding the BC treatment.

Background Regular exercise training represents an important modifier of arterial stiffness (AS). Therefore, sex‐specific relations between domains of physical activity (PA; commuting, domestic, and leisure‐time PA, including active sport and occupational PA) with AS were investigated. Methods and Results Stiffness index by digital photoplethysmography was investigated in 12 650 subjects from the GHS (Gutenberg Health Study). Self‐reported PA was evaluated by the “Short Questionnaire to Assess Health‐Enhancing Physical Activity” and reported as activity score peer week, being a combined measure of duration, frequency, and intensity of PA. Multivariable linear regression analysis demonstrated strong beneficial effects of repetitive activities, such as active commuting or leisure‐time PA–related walking on AS in men, but not in women. Lower AS associated with endurance training was also found among men and premenopausal women. In contrast, intense occupational PA was related to stiffer vessels in men ( P P =0.0021) in a fully adjusted model. Combination of both, performing endurance training and having stiffness index values below median, resulted in the best survival. In contrast, subjects with elevated stiffness index at baseline without any endurance activities demonstrated the worst survival. Conclusions In this population representative sample, a differential impact of domains of self‐reported PA on AS was demonstrated. Our data strengthen the importance of regular endurance PA to induce a reduction of AS, which, in turn, may improve cardiovascular prognosis. We also report deleterious effects of intense occupational PA on stiffness index, a finding that needs further confirmation by larger prospective trials.

Background Despite its established effectiveness, adherence to cardiac rehabilitation remains suboptimal. The purpose of our study is to examine whether mobile technology improves adherence to cardiac rehabilitation and other outcomes. Methods and Results We identified all enrollees of the cardiac rehabilitation program at Boston Medical Center from 2016 to 2019 (n=830). Some enrollees used a mobile technology application that provided a customized list of educational content in a progressive manner, used the patient’s smartphone accelerometer to provide daily step counts, and served as a 2‐way messaging system between the patient and program staff. Adherence to cardiac rehabilitation was defined as the number of attended sessions and completion of the program. Enrollees had a mean age of 59 years; 32% were women, and 42% were Black. Using 3:1 propensity matching for age, sex, race/ethnicity, education, smoking status, transportation time, diagnosis, and baseline depression survey score, we evaluated change in exercise capacity, weight, functional capacity, and nutrition scores. Those in the mobile technology group (n=114) attended a higher number of prescribed sessions (mean 28 versus 22; relative risk, 1.17; 95% CI, 1.04–1.32; P =0.009), were 1.8 times more likely to complete the cardiac rehabilitation program ( P =0.01), and had a slightly greater weight loss (pounds) following rehabilitation (−1.71; 95% CI, −0.30 to −3.11; P =0.02) as compared with those in the standard group (n=213); other outcomes were similar between the groups. Conclusions In a propensity‐matched, racially diverse population, we found that adjunctive use of mobile technology is significantly associated with improved adherence to cardiac rehabilitation and number of attended sessions.

Aim . To determine the levels of psychosocial factors (PSF) of the cardiovascular risk (CVR) in young men and women in gender dimension (on the model of Tyumen). Material and methods . An epidemiological cross-sectional study was conducted on a representative sample of the Tyumen population among men (n=1000, response 85,0%) and women (n=1000, response 70,3%) of 25-64 years old; 25,0% in each life decade. Data were obtained from young people aged 25-34 and 35-44 years old compared with a standardized age value (25-64 years). The PSF examination was carried out according to the algorithms of the WHO MONICA-Psychosocial Program. Results . Among young open urban population, the prevalence of moderate levels of depression and life exhaustion, a high level of hostility, moderate level of personal anxiety in men and a high level of personal anxiety in women was observed. In men of 25-34 years, compared with the general population values, the highest prevalence of the personal anxiety moderate level and hostility high level was revealed. There were high personal anxiety, depression and hostility levels among young women. In the gender dimension, young women were characterized by a significantly higher prevalence of high levels of CVR PSF: personal anxiety, depression, hostility, life exhaustion, moderate levels of life exhaustion, men —moderate levels of personal anxiety and hostility. Conclusion . The data obtained should be useful for formation of preventive cardiology programs on the basis of PSF assessing, starting from a young age.

Although significant progress has been made to reduce the global burden of cardiovascular disease, efforts have focused primarily on treatment of manifest disease rather than on prevention of events. An enormous opportunity exists to transition focus from intervention to providing equal attention to prevention of cardiovascular disease. The nascent specialty of "preventive cardiology" is emerging from the background of long-established services such as lipid, diabetes, hypertension, and general cardiology clinics. It is incumbent on the cardiology community to invest in cardiovascular prevention because past gains are threatened with the rising tide of obesity and diabetes. Now is the time to establish a dedicated preventive cardiology subspecialty to train the clinicians of the future. This American College of Cardiology Council Perspective aims to define the need for preventive cardiology as a unique subspecialty, broaches controversies, provides a structure for future training and education, and identifies possible paths forward to professional certification.

Background Aspirin (ASA) is the most used medication on the globe. ASA is a primary pillar of the secondary prevention of cardiovascular atherothromboembolic events. However, a fraction of the population does not respond to ASA as expected in a unique phenomenon called ASA resistance. Multiple mechanisms were described and studied in the literature to explain this phenomenon. Area of uncertainty ASA resistance is an interesting phenomenon that is worth studying and reviewing. Mechanisms behind this resistance are various and although the rarity of some, it is crucial for the modern health provider to be aware of such phenomenon and its possible explanations to provide more efficient preventive cardiology practice. Our study aimed to review and conclude the evidence behind ASA resistance and its implication on the cardiovascular health. Data sources We searched databases like PubMed, EMBASE, Ovid by midline, and Google Scholar for published articles and abstracts. Results Our systemic search revealed more than 100 articles in relation to ASA resistance. We selected 40 articles, which were relevant for this review. Various mechanisms were described in the literature, with few of them very well documented and understood. Main mechanisms include medication nonadherence, interaction with proton pump inhibitors, esterase-mediated ASA inactivation, post-coronary artery bypass grafting (CABG) MRP-4-mediated ASA consumption, cyclooxygenase-1 (COX-1) polymorphisms, high platelet turnover-associated regeneration of platelet COX-1, and the documented platelet ability of de novo COX-1 synthesis in response to thrombin and fibrinogen. Conclusion Multiple mechanisms of ASA resistance were described in the literature. Awareness of such interaction is important for medical practitioners. Bottom line, further studies and reviews are needed to further study this phenomenon and its implication on the cardiovascular health and hence reaching a valid evidence-based conclusion that might change the practice and improve the patient preventive health care.

Publisher's version (útgefin grein), Background: Cardiac rehabilitation (CR) is a clinically-effective but complex model of care. The purpose of this study was to characterize the nature of CR programs around the world, in relation to guideline recommendations, and compare this by World Health Organization (WHO) region. Methods: In this cross-sectional study, a piloted survey was administered online to CR programs globally. Cardiac associations and local champions facilitated program identification. Quality (benchmark of ≥ 75% of programs in a given country meeting each of 20 indicators) was ranked. Results were compared by WHO region using generalized linear mixed models. Findings: 111/203 (54.7%) countries in the world offer CR; data were collected in 93 (83.8%; N = 1082 surveys, 32.1% program response rate). The most commonly-accepted indications were: myocardial infarction (n = 832, 97.4%), percutaneous coronary intervention (n = 820, 96.1%; 0.10), and coronary artery bypass surgery (n = 817, 95.8%). Most programs were led by physicians (n = 680; 69.1%). The most common CR providers (mean = 5.9 ± 2.8/program) were: nurses (n = 816, 88.1%; low in Africa, p < 0.001), dietitians (n = 739, 80.2%), and physiotherapists (n = 733, 79.3%). The most commonly-offered core components (mean = 8.7 ± 1.9 program) were: initial assessment (n = 939, 98.8%; most commonly for hypertension, tobacco, and physical inactivity), risk factor management (n = 928, 98.2%), patient education (n = 895, 96.9%), and exercise (n = 898, 94.3%; lower in Western Pacific, p < 0.01). All regions met ≥ 16/20 quality indicators, but quality was < 75% for tobacco cessation and return-to-work counseling (lower in Americas, p = < 0.05). Interpretation: This first-ever survey of CR around the globe suggests CR quality is high. However, there is significant regional variation, which could impact patient outcomes., This project was supported by a research grant from York University 's Faculty of Health. The funder had no role in study design, data collection, data analysis, interpretation or writing of the report.

Background This study aimed at investigating the CV health and CV disease knowledge in terms of LS7 score among 3 age groups in Hong Kong. Methods A cross-sectional multicenter observational study was conducted to observe the CV health and disease risk knowledge in Hong Kong. Elderly subjects were recruited from 15 elderly centers, whereas young adults and the middle-aged were recruited from 6 on-campus health check sessions. Subjects’ demographics, lifestyle behavior and risk knowledge were obtained through questionnaire while their body mass index, random capillary blood glucose, blood cholesterol and blood pressure were measured. LS7 score and risk knowledge score was calculated. Results The LS7 of younger adult, middle-aged and elderly were 10.6 ± 1.3, 9.3 ± 1.9 and 9.7 ± 1.7 respectively. Only 0.6% participants have attained ideal CV health and 35.9% have 5 to 7 ideal CV health metrics. Elderly performed worst in risk knowledge with a score of 8.1 ± 3.3 while young adult and middle-aged were similar (9.6 ± 1.8 and 9.7 ± 1.5). 71% of the participants correctly identified ≥9 components. Logistic regression revealed that subjects aged ≤65 years (OR 2.341, 95% CI 1.779 to 3.080) and with tertiary education (OR 2.031, 95% CI 1.527 to 2.701) were more likely to obtain optimum LS7. No association was found between having optimum LS7 and full knowledge. Conclusion Only few adults in this study population had ideal CV health as defined by AHA. Knowledge has no association but young age and tertiary education has positive association with CV health.

Until 1990, lipid clinics in the United States existed only in academic medical centers, generally in close relationship with laboratory-based research programs. The advent of statin therapy, the success of major clinical trials to prevent or stabilize atherosclerotic cardiovascular disease, and organizational efforts highlighted by regional Lipid Disorders Training Centers and the newly formed National Lipid Association boosted the formation of lipid clinics and preventive cardiology clinics in private and academic settings. This roundtable discussion with 4 experts examines multiple aspects of lipid clinic operations: obtaining referrals, adapting to either the academic or community setting, organizing a team of providers, incorporating diet and lifestyle counseling as well as medication, establishing the pharmacist role, and gaining financial stability. Some issues are as yet unsettled, including the subspecialty home of lipidology, if any, and the diagnostic and management boundaries of practical lipid clinics. Achieving official recognition as a subspecialty has taken some steps forward but remains a challenge. Opportunities for advocacy need to be seized.

The current epidemiological situation in Poland is characterized by prevalence of cardiovascular diseases (CVD) as the main cause of mortality. In the paper the current state of knowledge on the importance of glycemic index (GI) and glycemic load (GL) in CVD prevention is presented, taking into consideration the latest recommendations on CVD prevention. In a nutrition strategy based on consumption of low GI/GL foods, the target of the intervention is the profile of dietary carbohydrates which is treated as a modulator of glycemic response. In the light of the current state of research, there is no reason to treat GI/GL values as markers of pro-health qualities of the dietary plan recommended in CVD prevention to individuals with normal glucose homeostasis. However, the preventive potential of diets characterized by low GI/GL deserves a more extensive application in patients with glucose homeostasis disturbances, including those with prediabetes and insulin resistance syndrome. Taking into account the relations between abnormal carbohydrate metabolism and a risk of developing diabetes, followed by CVD, the benefits of low-glycemic diets in individuals with impaired glucose homeostasis can indirectly result in lowering the risk of CVD. It is reasonable to conduct further clinical studies on the relevance of low GI/GL diets in preventive cardiology.

Aims The primary aim of the programme was a minimum of a 5% weight reduction of the initial weight, while the secondary outcomes were a reduction in participants’ body mass index (BMI), waist circumference (WC), blood pressure (BP), AUDIT-C score and an increase in the Mediterranean diet (MD) score and an improvement in physical activity levels. Methods This 'before and after' study was a 10-week weight management (WM) programme and it was developed and delivered in community pharmacies in Patras chosen for convenience, thus consisting the first service of its type in Greece. The sample size was calculated (n = 96) based on the mean BMI for a Greek male and female individual, and the standard deviation (SD) of weight at baseline of 14 kg. Results Nearly every participant enrolled in the 20 participating pharmacies, 97.4% (n = 114/117), achieved the programme’s aim, losing at least 5% of their initial weight. The mean percentage of total weight loss of the 117 participants at the 10th week was 8.97% (SD 2.65), and the t-test showed statistically significant results (P-value P-value = 0.004) and female (P-value P-value Conclusion This study provides the first evidence that Greek pharmacists have the potential to play an important role within primary healthcare and that after training they are able to provide public health services for both the public’s benefit and their clinical role enhancement.

Background Although tobacco product use and transitions have been characterized in the general population, few studies have focused on individuals with established cardiovascular disease (CVD) in a population‐based sample. Methods and Results We examined tobacco use prevalence and longitudinal patterns of tobacco product transitions in adults (≥18 years) of the nationally representative PATH (Population Assessment of Tobacco and Health) study, from 2013 to 2014 (Wave 1) through 2016 to 2018 (Wave 4). Prevalent CVD was classified through self‐report of having had a heart attack, heart failure, stroke, or other heart condition. Factors associated with tobacco product use and transitions were investigated using survey logistic regression. We examined 2615 participants with self‐reported CVD at Wave 1. Overall, 28.9% reported current tobacco use, equating to ≈6.2 million adults in the United States with prevalent CVD and current tobacco use. Among adults with CVD who are current tobacco users, the most commonly used product was cigarettes (82.8%), followed by any type of cigar (23.7%), and e‐cigarette use (23.3%). E‐cigarette use without concurrent cigarette use among participants with prevalent CVD was uncommon (1.1%). Factors associated with tobacco use were younger age, male sex, had lower education level, and lack of knowledge about the association between smoking and CVD. Men with prevalent CVD were less likely to use e‐cigarettes compared with women (odds ratio [OR], 0.7; 95% CI, 0.5–0.9). Among cigarette users with CVD, transition rates between Waves 1 and 4 demonstrated Conclusions Despite known harmful cardiovascular effects, over one fourth of adults with prevalent CVD use tobacco products and few quit smoking over the 4 waves of the PATH data set.

Background There is limited evidence of long‐term impact of exercise‐based cardiac rehabilitation (CR) on clinical end points for patients with atrial fibrillation (AF). We therefore compared 18‐month all‐cause mortality, hospitalization, stroke, and heart failure in patients with AF and an electronic medical record of exercise‐based CR to matched controls. Methods and Results This retrospective cohort study included patient data obtained on February 3, 2021 from a global federated health research network. Patients with AF undergoing exercise‐based CR were propensity‐score matched to patients with AF without exercise‐based CR by age, sex, race, comorbidities, cardiovascular procedures, and cardiovascular medication. We ascertained 18‐month incidence of all‐cause mortality, hospitalization, stroke, and heart failure. Of 1 366 422 patients with AF, 11 947 patients had an electronic medical record of exercise‐based CR within 6‐months of incident AF who were propensity‐score matched with 11 947 patients with AF without CR. Exercise‐based CR was associated with 68% lower odds of all‐cause mortality (odds ratio, 0.32; 95% CI, 0.29–0.35), 44% lower odds of rehospitalization (0.56; 95% CI, 0.53–0.59), and 16% lower odds of incident stroke (0.84; 95% CI, 0.72–0.99) compared with propensity‐score matched controls. No significant associations were shown for incident heart failure (0.93; 95% CI, 0.84–1.04). The beneficial association of exercise‐based CR on all‐cause mortality was independent of sex, older age, comorbidities, and AF subtype. Conclusions Exercise‐based CR among patients with incident AF was associated with lower odds of all‐cause mortality, rehospitalization, and incident stroke at 18‐month follow‐up, supporting the provision of exercise‐based CR for patients with AF.
