Introduction Acute myocardial infarction (AMI) is a major cause of morbidity and mortality in our country. It is very important to have data on the reality of this entity in Argentina as a starting point for the development of prevention policies and treatment improvement. Objective The aim of the study was to describe demographic variables, situations associated to stress, established treatments, implementation times, in-hospital complications and medication at discharge of patients with AMI admitted to centers associated to the Argentine Council of Residents in Cardiology (CONAREC). Methods Between December 2009 and July 2010, 1182 consecutive patients admitted to 45 centers across the country with a diagnosis of AMI with or without ST segment elevation were included in the study. Results Mean age was 64 ± 12 years; 705 patients presented AMI with ST segment elevation (STEMI) and 477 without ST segment elevation (NSTEMI). In the STEMI group, the reperfusion rate was 92% of eligible patients, with primary angioplasty in 80% of cases. In this group, prehospital time delay was 165 minutes and door-to-balloon time was 80 minutes. In the NSTEMI group), coronary angiography was performed in 75% of patients and 46% underwent angioplasty. The main complication was the development of heart failure (22% in the STEMI group and 11% in the NSTEMI group, followed by bleeding and arrhythmias. Mortality was 8.8% in the STEMI group and 5.1% in the NSTEMI group. Conclusions Patients with AMI admitted to centers with medical residency present with a high rate of reperfusion and treatment at hospital discharge, in agreement with international recommendations. We have found aspects to be improved such as the high prevalence of risk factors and prolonged prehospital time delays, situations which have not changed in the last 15 years.
