Key result
Cardiac rehabilitation after acute myocardial infarction was associated with a 59% reduction in 5-year mortality compared to non-participation (HR 0.41; 95% CI 0.27-0.63).
Why the study?
Cardiac rehabilitation participation remains low in parts of Europe and Asia including Korea, prompting investigation of its effects on AMI prognosis.
Does cardiac rehabilitation reduce 5-year mortality and MACE in patients with acute myocardial infarction?
Population
6743 AMI patients across 11 tertiary hospitals in Korea
Comparison
Outpatient cardiac rehabilitation vs no cardiac rehabilitation
Design

Participation in cardiac rehabilitation after acute myocardial infarction is associated with a 59% reduction in 5-year mortality.
Kim et al. (2020) conducted a cohort in Acute myocardial infarction (AMI) (n=6,743). Cardiac rehabilitation vs. No cardiac rehabilitation was evaluated on Total 5-year mortality (reported as 5-year survival rate) (HR 0.41, 95% CI 0.27-0.63). Cardiac rehabilitation after acute myocardial infarction was associated with a 59% reduction in 5-year mortality compared to non-participation (HR 0.41; 95% CI 0.27-0.63).
