Key words: Reperfusion, acute myocardial infarction, opportunity. ABSTRACT In the Acute ST-Elevation Myocardial Infarction (STEMI) the reperfusion therapy (RT) diminishes the morbidity and mortality. Nevertheless, a proportion of the patients with this diagnosis does not receive the benefit of this treatment. Objective: To know the number of patients with STEMI who underwent RT and the opportunity whereupon this treatment was applied. Material y methods: The data base of the patients who entered the Unit of Cardiovascular Intensive Care of our hospital from January 2005 to June 2006 with the STEMI diagnosis were reviewed. The type of treatment and opportunity of the same were evaluated. Results: A total of 144 patients, between 28 and 94 years (61.1 ± 11.5 years) were enrolled. 72.2% (104) were men. 59.7% (86) underwent fibrinolysis therapy, 5.5% (8) underwent percutaneous coronary intervention (PCI) and 34.7% (50) did not receive reperfusion therapy. 32.5% (28) underwent fibrinolysis after 6 hours. In 84.8% (73) of the cases use rTPA and 15.2% (13) streptokinase. Conclusions: 34.7% of the patients with STEMI did not receive reperfusion therapy. Of the patients who underwent fibrinolysis, few were in the recommended time. It is necessary to implement strategies that allow to increase the proportion of patients with STEMI that receive the benefit of the reperfusion therapy as well as to improve the time in which it is applied.
