Exercise-based cardiac rehabilitation significantly reduces the risk of fatal and/or non-fatal myocardial infarction in patients with coronary heart disease.
If you have coronary heart disease, engaging in supervised exercise-based cardiac rehabilitation is a highly effective way to lower your risk of having another heart attack. It is safe and recommended by major health organizations.
StrongSupportsHIGH confidence
Exercise-based CR results in a large reduction in fatal and/or non-fatal MI up to 12 months' follow-up (RR 0.72, 95% CI 0.55 to 0.93; 22 trials; high certainty evidence).
Why this rating
The review is a Cochrane systematic analysis of 85 RCTs with 23,430 participants, assigning 'High' certainty to MI outcomes using GRADE.
