Heart failure after myocardial infarction significantly increases mortality risk regardless of ejection fraction, though overall post-MI mortality has declined over time due to improved heart failure survival.
Supports closer post-MI heart failure monitoring irrespective of LVEF; leaves open timing-specific intervention trials.
HF markedly increases the risk of death after MI. This excess risk is similar regardless of ejection fraction but greater for delayed- versus early-onset HF. Mortality after MI declined over time, primarily as a result of improved HF survival.
