Physical performance and outcomes after myocardial infarction in older patients undergoing multidomain cardiac rehabilitation

In older myocardial infarction patients, baseline physical performance is a strong and independent predictor of adverse cardiovascular outcomes without modifying the benefit of multidomain cardiac rehabilitation. Gait speed represents a simple and pragmatic marker of risk, and functional improvement over time is associated with better prognosis.

Interaction between baseline SPPB and treatment assignment
- No interaction; consistent benefit of intervention across levels of physical performance
SPPB improvement ≥1 point during follow-up
- Associated with lower risk of adverse outcomes
