Complete Revascularization Versus Treatment of the Culprit Artery Only in ST Elevation Myocardial Infarction: A Multicenter Registry

Abstract Background Data on the management and prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease are limited in Brazil, showing that the available revascularization strategies should be investigated Objective To assess the outcomes of complete revascularization versus treatment of the culprit artery only in patients with STEMI and multivessel disease. Methods A prospective cohort study was conducted at two medical centers in southern Brazil with a 1-year follow-up after the index procedure. The primary outcome was a composite of cardiac death, reinfarction, or recurrent angina, while the secondary outcome was stroke, nonfatal cardiac arrest, major bleeding, or need for reintervention. The probability of outcomes occurring was compared between the groups using binary logistic regression. A p-value
