Introduction Considering that the acute myocardial infarction (AMI) is the most frequent cause of death in our country, this multicentric registry intends to establish a vision of the epidemiological reality (limited to the participating sites) aimed at obtaining information in regards to the clinical management and in-hospital morbi-mortality. Objective To analyze the epidemiological, clinical, therapeutic uses and mortality in AMI in sites affiliated to the Argentine society of Cardiology. Material and Methods Five hundred and fifteen patients from 74 intensive care units throughout the country, registered during 2 consecutive months, within the period April-December 2005. Results The median age was 62 years; 24% were women. Six percent did no show any risk factor whereas 38% had at least three factors. 27.9% of the patients had a history of some type of coronary disease. 65.4% were admitted within the first 6 hours; in 42.2% AMI location was anteiror, with Killip and Kimball A in 77.6% of the patients. Upon admission, 74.8% showed supra imbalance of the ST segment and 4.9% LBBB. 53% underwent reperfusion therapy (42.3% thrombolytic therapy and 57.7% primary angioplasty), 80.3% if we include patients eligible for reperfusion therapy (n=320). The most frequent complication was cardiac failure that reached 20.2% whereas 11.3% showed post infarct angina and 4.3% reinfarction. In-Hospital mortality was 12.6%. At discharge, 95.1% were administered aspirin, 78.8% beta blockers, 72.8% statins, and 55.9% clopidogrel. Conclusions Still, an important range of patients eligible for reperfusion does not receive it. Primary angioplasty was the reperfusion strategy mostly administered; probably related to the characteristics of the participating sites. We considered that the efforts should be focused on the strategies that most likely will translate in increased benefits.
