The aim of the study was to identify the optimal time window for performing effective percutaneous coronary reperfusion in patients with non-ST-segment elevation acute myocardial infarction (NSTEMI) who are part of the low ischemic risk group. 252 patients with NSTEMI and low ischemic risk who underwent coronary angioplasty up to 30 days after the onset of the infarction were evaluated the second day post-procedurally and at a distance of 6 months. The general group was randomized depending on the echocardiographic evolution. 131 patients with unfavorable evolution and 121 with more complete restoration of left ventricular contractile function. The time windows from the onset of myocardial infarction symptoms in which percutaneous myocardial reperfusion was applied were studied. Following the study, the time interval of 73 hours -14 days proved to be optimal in which a more favorable clinical and echocardiographic evolution is ensured.
