AB Objective A systematic review was undertaken to assess the effects of exercise-based cardiac rehabilitation (CR) for patients with stable angina.Methods Databases (Cochrane Central Register of Controlled Trials, MEDLINE, Embase and CINAHL) were searched up to October 2017, without language restriction. Randomised trials comparing CR programmes with no exercise control in adults with stable angina were included. Where possible, study outcomes were pooled using meta-analysis. Grading of Recommendations Assessment, Development and Evaluation was used to assess the quality of evidence. The protocol was published on the Cochrane Database of Systematic Reviews.Results Seven studies (581 patients), with a median of 12-month follow-up, were included. The effect of exercise-based CR on all-cause mortality (risk ratio (RR) 1.01, 95 % CI: 0.18 to 5.67), acute myocardial infarction (RR 0.33, 95% CI: 0.07 to 1.63) and cardiovascular-related hospital admissions (RR 0.14, 95% CI: 0.02 to 1.1) relative to control were uncertain. We found low-quality evidence that exercise-based CR results in a moderate improvement in exercise capacity (standard mean difference 0.45, 95% CI: 0.20 to 0.70). There was limited and very low-quality evidence for the effect of exercise-based CR on health-related quality of life (HRQoL), adverse events and costs. No data were identified on cost-effectiveness or return to work.Conclusions Exercise-based CR may improve the short-term exercise capacity of patients with stable angina pectoris. Well-designed randomised controlled trials are needed to definitely determine the impact of CR on outcomes including mortality, morbidity, HRQoL, and costs in the population of patients with stable angina receiving contemporary medical therapy.
