Increased Cardiovascular Disease Mortality Associated With Excessive Exercise in Heart Attack Survivors
This prospective cohort study evaluated 2,377 myocardial infarction (MI) survivors over a mean follow-up of 10.4 years to examine the relationship between exercise volume and cardiovascular mortality. Findings revealed that moderate physical activity (up to 7.2 MET-hours/day) significantly reduced cardiovascular disease (CVD) mortality, with optimal benefits at 5.4–7.2 MET-h/day. However,
