[Short-term and long-term mortality comparison between myocardial infarction with and without ST segment elevation undergoing myocardial revascularization by percutaneous coronary angioplasty].

Objectives: To compare the early and late mortality of patients that have suffered an ST segment elevation myocardial infarction (STEMI) and a non-ST segment elevated myocardialinfarction (NSTEMI).

Methods: Retrospective study of patients treated at the Regional Clinical Hospital of Concepción from January the 1rst 2013 to December 31 rst 2015, with diagnostic of STEMI and NSTEMI that required coronary angioplasty during their hospitalization. Descriptive and multivariate analysis was performed to compare mortality rates between both populations before 30 days and in follow-up at 4 years.
