Abstract Background Unhealthy behaviors of coronary heart disease (CHD) patients are closely related to the occurrence of major heart events, which increases the readmission rate and brings a heavy economic burden to families and society. Therefore, it is necessary for health care workers to take active preventive and therapeutic measures to keep or establish healthy behaviors of patients. Positive psychological intervention has been proved to be effective, but it has not been reported in the field of CHD in China. The purpose of this study is to explore the effects of positive event recording based on positive psychology on the healthy behaviors, readmission rate, and anxiety of patients with CHD, in order to provide new ideas for the development of secondary prevention strategies for CHD. Methods This is a prospective, single-center, randomized controlled trial (RCT). The subjects will be enrolled from the Department of Cardiology, the First Affiliated Hospital of Soochow University. There are 80 cases in total; according to the random number table, the subjects are randomly divided into the intervention group (n = 40) and the control group (n = 40). The patients in the intervention group will receive the intervention of recording positive events once a week for 3 months, while the patients in the control group receive conventional nursing. The primary outcomes will include healthy behaviors, readmission rate, and anxiety, and the secondary outcomes will include psychological capital, subjective well-being, and corresponding clinical laboratory indicators. The protocol was approved by the Medical Ethics Committee of Soochow University (approval no. SUDA20200604H01) and is performed in strict accordance with the Declaration of Helsinki formulated by the World Medical Association. All participants provide written informed consent. Discussion This study will verify whether positive event recording based on positive psychology can make patients maintain healthy behaviors, reduce readmission rate, and improve anxiety after PCI. Then, this study will provide new ideas and references for the development of secondary prevention strategies for patients with CHD. Trial registration Chinese Clinical Trials Registry 2000034538.

BackgroundPatients with coronary heart disease (CHD) often experience anxiety, but the current studies on anxiety mostly focused on a certain point in time. Therefore, this study aimed to investigate the dynamic changes of peri-procedure anxiety, status of post-procedure quality of life, and cardiovascular readmission rates in patients with CHD who undergoing elective percutaneous coronary intervention (PCI), and to analyze the influence of peri-procedure anxiety on quality of life and readmission rate after PCI.MethodsThis prospective study was conducted at Changshu NO.1 People's Hospital. A total of 220 patients with CHD undergoing elective PCI were selected as study subjects. The general information, clinical data, anxiety, quality of life and readmission of patients were collected. Multivariate linear regression was used to examine the effect of peri-procedure anxiety on quality of life, and multivariate logistic regression was used to analyze the influence of peri-procedure anxiety on readmission rate.ResultsThis study showed the anxiety scores at hospitalization appointment(T1), 3 days before procedure(T2), 1 day before procedure(T3), 1 day after procedure(T4) were 57(55,61),64(61,68),54(51.58), and 54(50,60), respectively. And, at 3 months and 6 months after PCI, the scores of Seattle Angina Questionnaire (SAQ) were 346.61(319.06,366.52) and 353.34(334.18,372.84) respectively. During 6 months follow-up, 54 cases were readmitted, with a readmission rate of 25.5%. Statistical analysis showed that T1 with anxiety (P = 0.002) and T2 with anxiety (P = 0.024) were independent risk factors for treatment satisfaction at 3 months after PCI. Anxiety in T4 (P = 0.005) was an independent risk factor on the angina frequency at 6 months after PCI. T2 with anxiety (B = 1.445, P = 0.010, 95%CI:1.409-12.773) and T4 without anxiety (B = -1.587, P = 0.042, 95%CI:-0.044-0.941) were risk factors affecting readmission for cardiovascular reasons within 6 months.ConclusionPatient anxiety at T1 and T2 affects the treatment satisfaction dimension of the SAQ at 3 months after PCI, and anxiety at T4 affects the angina frequency dimension of the SAQ at 6 months after PCI. Anxiety at T2 and no anxiety at T4 increase short-term readmission rates. In the future, interventions should be strengthened at various time points in the peri-procedure period to improve post-procedure rehabilitation effect.

Objective: To examine the present state of fatigue in young and middle-aged patients with coronary heart disease (CHD) and to identify the elements that may be affecting it. Methods: From December 2020 to June 2021, 240 young and middle-aged patients with CHD who were being treated in the cardiology department of a tertiary care hospital in Suzhou were chosen using a convenience sampling method in order to gather data on the patients' sociodemographic status, fatigue, social support, and stress. Results: Of the 240 disseminated questionnaires, 220 valid responses were returned, resulting in an effective recovery rate of 91.67%. The frequency of exhaustion was 51.8%, and the fatigue score was (5.27 ± 2.77). The stress score was (11.15 ± 3.36), while the overall social support score was (39.13 ± 4.72). Binary logistic regression analysis indicated that age, exercise, staying up late, stress, social support, high-sensitivity troponin T, high-density lipoprotein, and ejection fraction were independent risk factors for fatigue in young and middle-aged patients with CHD (P < 0.05). Conclusions: Fatigue is more prevalent in young and middle-aged patients with CHD. Clinical nurses can create a unique management plan for patients based on their lifestyle and behavioral patterns, stress levels, social support, and clinical signs to reduce fatigue.
