Exercise-Based Cardiac Rehabilitation for Coronary Heart Disease
This study confirms that exercise-based cardiac reabilitation reduces cardiovascular mortality and provides data showing reductions in hospital admissions and improvements in quality of life.

Although recommended in guidelines for the management of coronary heart disease (CHD), concerns have been raised about the applicability of evidence from existing meta-analyses of exercise-based cardiac rehabilitation (CR). The goal of this study is to update the Cochrane systematic review and meta-analysis of exercise-based CR for CHD.
A total of 63 studies with 14,486 participants with median follow-up of 12 months were included. Overall, CR led to a reduction in cardiovascular mortality (relative risk: 0.74; 95% confidence interval: 0.64 to 0.86) and the risk of hospital admissions (relative risk: 0.82; 95% confidence interval: 0.70 to 0.96). There was no significant effect on total mortality, myocardial infarction, or revascularization. The majority of studies (14 of 20) showed higher levels of health-related quality of life in 1 or more domains following exercise-based CR compared with control subjects.
