IntroductionAcute myocardial infarction (AMI) is a major cause of morbidity and mortality in ourcountry. It is very important to have data on the reality of this entity in Argentina asa starting point for the development of prevention policies and treatment improvement.ObjectiveThe aim of the study was to describe demographic variables, situations associated tostress, established treatments, implementation times, in-hospital complications andmedication at discharge of patients with AMI admitted to centers associated to theArgentine Council of Residents in Cardiology (CONAREC).MethodsBetween December 2009 and July 2010, 1182 consecutive patients admitted to 45centers across the country with a diagnosis of AMI with or without ST segment elevationwere included in the study.ResultsMean age was 64 ± 12 years; 705 patients presented ST-segment elevation myocardialinfarction (STEMI) and 477 non- ST-segment elevation myocardial infarction(NSTEMI). In the STEMI group, reperfusion rate was 92% of eligible patients, withprimary angioplasty in 80% of cases. In this group, prehospital time delay was 165minutes and door-to-balloon time was 80 minutes. In the NSTEMI group, coronaryangiography was performed in 75% of patients and 46% underwent angioplasty. Themain complication was the development of heart failure (22% in the STEMI groupand 11% in the NSTEMI group), followed by bleeding and arrhythmias. Mortalitywas 8.8% in the STEMI group and 5.1% in the NSTEMI group.ConclusionsPatients with AMI admitted to centers with medical residency present a high rateof reperfusion and treatment at hospital discharge, in agreement with internationalrecommendations. Aspects to be improved are the high prevalence of risk factors andprolonged prehospital time delays, situations which have not changed in the last 15years.
