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

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.
