The study aimed to evaluate how delaying the opening of the infarct-related artery (IRA) impacts late left ventricular remodeling following an acute anterior myocardial infarction (AAMI).
Sixty-four patients were divided into two groups: one receiving successful percutaneous coronary intervention (PCI) and the other not receiving PCI, with their heart function monitored at multiple intervals post-AAMI.
Results indicated that while early metrics like left ventricular function were similar across both groups, those in the successful PCI group experienced significantly less increase in heart chamber sizes and a lower incidence of congestive heart failure events over six months.
