[In-hospital complications of acute myocardial infarction. Incidence and timing of their occurrence].

Although ST-segment elevation myocardial infarction (STEMI) mortality decreased with the progress of reperfusion, the incidence of hospital complications has not changed. We aimed to describe the incidence of STEMI complications in the coronary unit, the timing of their occurrence and to identify their predisposing and protective factors. This is a prospective analysis of all consecutive patients with STEMI admitted to a coronary care unit of a third level reference hospital from September 2017 to March 2020.
