Exercise-based cardiac rehabilitation reduces myocardial infarction and hospitalisation in coronary heart disease.

Systematic review of 107 randomised trials (26,886 adults with coronary heart disease) comparing exercise-based cardiac rehabilitation versus no exercise control. At short-term follow-up (6-12 months), exercise reduced myocardial infarction (RR 0.72), all-cause hospitalisation (RR 0.65), and likely reduced all-cause mortality (RR 0.86). Health-related quality of life improved across multiple domains, and eight economic studies confirmed cost-effectiveness.

Design
Meta analysis
Sample size
26,886
Duration
6 months
Population
Adults with coronary heart disease (CHD), mostly post-MI or post-revascularisation; mean age 47–81 years. 78% of trials included women, who represented 17% of total participants overall.
Primary outcome
Mortality (all-cause and cardiovascular), fatal and non-fatal myocardial infarction (MI), revascularisation (CABG and PCI), and hospitalisation (all-cause and cardiovascular).
Effect size
Short-term follow-up (6–12 months): All-cause mortality RR 0.86 (95% CI 0.74–1.00, moderate-certainty); cardiovascular mortality RR 0.87 (95% CI 0.68–1.11, moderate-certainty); MI RR 0.72 (95% CI 0.54–0.95, high-certainty); CABG RR 1.00 (95% CI 0.78–1.28, high-certainty); PCI RR 0.86 (95% CI 0.65–1.13, moderate-certainty); all-cause hospitalisation RR 0.65 (95% CI 0.51–0.82, moderate-certainty); cardiovascular hospitalisation RR 0.80 (95% CI 0.35–1.82, low-certainty). Long-term follow-up (>12 months): exercise-based CR associated with reduced cardiovascular mortality and MI. HRQoL showed clinically meaningful increases across SF-36 subscales and EQ-5D scores up to 12 months. Eight economic evaluation studies showed exercise-based CR cost-effective.
