Registry of "early latecomer" patients with acute ST-segment elevation myocardial infarction at the Instituto Nacional Cardiovascular INCOR - Peru.

Objective: To assess the features of asymptomatic patients with acute ST segment elevation myocardial infarction who presents to the emergency with more than 12h of evolution, and if there is a benefit of an invasive versus medical therapy.

Methods: Retrospective, cohort study from January 2012 to December 2014, we compare the outcomes at 6 and 12 months of follow up of the invasive group versus the conservative group.

Results: There were no differences in outcomes at 12 months between an invasive versus a conventional strategy; but, looking at the reperfusion state, we found more risk of death and heart failure at 12 months in the no-reperfused group versus the reperfused group (40% versus 0%, OR: 2, CI: 1.
