INTRODUCTION: Exercise -based cardiac rehabilitation (CR) plays a critical role in coronary heart disease (CHD) management. There is heritage in the effect of exercise -based CR with different exercise programs or intervention settings. This study developed an evidence matrix that systematically assesses, organizes, and presents the available evidence regarding exercise -based CR in CHD management. EVIDENCE ACQUISITION: A comprehensive literature search was conducted across six databases. Two reviewers screened the identified literature, extracted relevant data, and assessed the quality of the studies. An evidence -mapping framework was established to present the findings in a structured manner. Bubble charts were used to represent the included systematic reviews (SRs). The charts incorporated information, exercise prescriptions, outcome indicators, associated P -values, research quality, and the number of original studies. A descriptive analysis summarized the types of CR, intervention settings, influential factors, and adverse events. EVIDENCE SYNTHESIS: Sixty-two SRs were included in this analysis, focusing on six exercise types in addition to assessing major adverse cardiovascular events (MACE), cost and rehabilitation outcomes. The most commonly studied exercise types were unspecified (28 studies, 45.2%) and aerobic (11 studies, 17.7%) exercises. All -cause mortality was the most frequently reported MACE outcome (22 studies). Rehabilitation outcomes primarily centered around changes in cardiac function (135 outcomes from 39 SRs). Only 8 (12.9%) studies were rated as "high quality." No significant adverse events were observed in the intervention group. Despite some variations among the included studies, most SRs demonstrated the benefits of exercise in improving one or more MACE or rehabilitation outcomes among CHD patients. CONCLUSIONS: The proportion of high -quality evidence remains relatively low. Limited evidence is available regarding the effectiveness of specific exercise types and specific populations, necessitating further evaluation.

BACKGROUND: Coronary artery disease is one of the most important health problems among heart diseases in the world, with high morbidity and mortality. Lifestyle changes in particular are recommended in the latest guidelines for implementing secondary prevention. AIM: The aim of this study was to evaluate the effectiveness of telehealth interventions as a part of secondary prevention compared to routine care in those with coronary artery disease. METHOD: The systematic review with meta-analysis was performed in accordance with Cochrane methods. Science Direct, Springer Link, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, ProQuest and Network Digital Library databases were searched between 2000 and 2018 up to February 2018. The studies chosen conformed to PICOS inclusion and exclusion criteria. The risk of bias was assessed using the Cochrane risk of bias tool. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was used in reporting the study. RESULTS: Twenty-four studies with a total of 6773 study participants met the inclusion criteria. It was found that telephone call interventions were the most commonly used, text message interventions came second with seven studies, telephone calls in combination with messages were used in four studies and telemonitoring was used in two studies. Compared to routine care, telehealth interventions had moderate significant effects in reducing waist circumference, total cholesterol and triglyceride, improving medication adherence and physical activity, and had small significant effects in reducing blood pressure and smoking cessation. No significant publication bias was found in the main outcomes. CONCLUSION: Results showed that the telehealth interventions yielded positive outcomes in lifestyle changes for coronary artery disease. Therefore, telehealth interventions can be used for effective secondary prevention by health professionals who care for individuals with coronary artery disease. Additionally, this study will provide guidance for studies on the development of telehealth intervention.

Background The burden of coronary heart disease (CHD) worldwide is one of great concern to patients and healthcare agencies alike. Exercise-based cardiac rehabilitation aims to restore patients with heart disease to health. Objectives To determine the effectiveness of exercise-based cardiac rehabilitation (exercise training alone or in combination with psychosocial or educational interventions) on mortality, morbidity and health-related quality of life of patients with CHD. Search strategy RCTs have been identified by searching CENTRAL, HTA, and DARE (using The Cochrane Library Issue 4, 2009), as well as MEDLINE (1950 to December 2009), EMBASE (1980 to December 2009), CINAHL (1982 to December 2009), and Science Citation Index Expanded (1900 to December 2009). Selection criteria Men and women of all ages who have hadmyocardial infarction (MI), coronary artery bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA), or who have angina pectoris or coronary artery disease defined by angiography. Data collection and analysis Studies were selected and data extracted independently by two reviewers. Authors were contacted where possible to obtain missing information. Main results This systematic review has allowed analysis of 47 studies randomising 10,794 patients to exercise-based cardiac rehabilitation or usual care. In medium to longer term (i.e. 12 or more months follow-up) exercise-based cardiac rehabilitation reduced overall and cardiovascular mortality [RR 0.87 (95% CI 0.75, 0.99) and 0.74 (95% CI 0.63, 0.87), respectively], and hospital admissions [RR 0.69 (95% CI 0.51, 0.93)] in the shorter term (< 12 months follow-up) with no evidence of heterogeneity of effect across trials. Cardiac rehabilitation did not reduce the risk of total MI, CABG or PTCA. Given both the heterogeneity in outcome measures and methods of reporting findings, a meta-analysis was not undertaken for health-related quality of life. In seven out of 10 trials reporting health-related quality of life using validated measures was there evidence of a significantly higher level of quality of life with exercise-based cardiac rehabilitation than usual care. Authors' conclusions Exercise-based cardiac rehabilitation is effective in reducing total and cardiovascular mortality (in medium to longer term studies) and hospital admissions (in shorter term studies) but not total MI or revascularisation (CABG or PTCA). Despite inclusion of more recent trials, the population studied in this review is still predominantly male, middle aged and low risk. Therefore, well-designed, and adequately reported RCTs in groups of CHD patients more representative of usual clinical practice are still needed. These trials should include validated health-related quality of life outcome measures, need to explicitly report clinical events including hospital admission, and assess costs and cost-effectiveness.
