    Background: Primary angioplasty is considered the best repefusion therapy in The treatment of ST-segment elevation))myocardial infarction (STEMI). However, thrombolysis the reperfusion, method most commonly used, due to its wide availability reduced costs and case of administration. Aim To compare in-hospital mortality, in STEMI patients according to repefusion therapy. Material and Methods. 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 analized in each group, using a logistic regression method, to assess risk factors associated with mortality. Results: We included 3,255 patients. Global mortality was 9.9% (75% in men and 16.7% in women, p < 0.001). Mortality in patients treated with thrombolytics, was 10.2% (76% in men and 18.7% in women, p < 0.01). The figure for patients treated with primary angioplasty, was 4.7% (2.5% in men and 13% in women, p < 0.01), and in patients without reperfusion, was 11.6% (9.8% in men and in 15.4% women, p < 0.01). In each group women were older, had a higher prevalence of hypertension and a higher percentage of Killip 3-4 infarctions. Logistic regression showed that angioplasty) compared with no repefusion, was associated with a reduced mortality only in men. The use of thrombolytics in women was associated with a higher mortality. Conclusions: Primary angioplasty was the reperfusion therapy associated to the lower mortality in STEMI. Use of thrombolytics in women was associated with a higher mortality rate than in non reperfused women
