Abstrakt:	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. Results: 1838 patients were included with an average follow-up of 82 months. The population with STEMI was 921 and was younger, with a higher prevalence of arterial hypertension and smoking. The population with NSTEMI had a higher prevalence of diabetes mellitus, a lower glomerular filtration rate, and a higher incidence of left main coronary artery disease and chronic occlusions. At the end of follow-up, the overall survival rate was 76%, with no significant difference between the two groups. Patients with STEMI had twice the risk of dying in the first 30 days (Long Rank: 0.012). After 30 days, mortality was higher in the NSTEMI group (80.8% vs 75.6%). Conclusions: This study did not show significant differences in overall mortality during prolonged follow-up of patients with STEMI and NSTEMI. The STEMI group had a higher risk of early death, while the NSTEMI group had higher long-term mortality.
