ln-hospital mortality after ST-segment elevation myocardial infarction according to reperfusion therapy

Primary angioplasty is considered the best reperfusion therapy in the treatment of ST-segment elevation myocardial infarction (STEMI). However, thrombolysis is the reperfusion method most commonly used, due to its wide availability, reduced costs and ease of administration. To compare in-hospital mortality in STEMI patients according to reperfusion therapy. Patients admitted to Chilean hospitals participating in the GEMI network, from 2001 to 2005, with STEMI were included. They were divided in three groups: a) treated with thrombolytics, b) treated with primary angioplasty, c) without reperfusion procedure. In-hospital mortality according to gender, was analyzed in each group, using a logistic regression method, to assess risk factors associated with mortality. We included 3,255 patients. Global mortality was 9.9% (7.5% in men and 16.7% in women, p
