[Admission XXXX and mortality of ST segment elevation @entity583 ].

@entity1 @entity6 @entity1602 @entity1188 @entity583 @entity4854
BACKGROUND: @entity4854 at admission has been associated to an adverse prognosis in @entity1 with @entity583 ( @entity583 ). However, its impact over the results of reperfusion therapies in @entity1 with STEMI is still a matter of controversy. AIM: to determine the impact of admission @entity4854 on hospital and long term mortality, according to the method of reper-fusion utilized in @entity1 with STEMI. MATERIAL AND METHODS: prospective registry of 1,634 consecutive @entity1 aged 60    12 years (77% male), from 3 participating hospitals in the Chilean Registry of @entity583 (GEMI). We evaluated demographic, clinical and laboratory variables, reperfusion method used, hospital and long term mortality. The impact of @entity4854 on hospital and long term mortality was evaluated by a logistic regression analysis and Cox risk, respectively, adjusted by Thrombolysis in @entity583 (TIMI) risk score. RESULTS: twenty four percent of @entity1 were @entity6 and in 45%, the @entity1188 was located on the anterior wall. The mean TIMI risk score was 3.2    2.4. @entity4854 at entry was associated to a greater hospital and long term mortality, independently of the reperfusion strategy utilized. Primary angioplasty was associated to a greater benefit, compared to thrombolysis among @entity1602 @entity1 with an odds ratio: 2.9, 95% confi dence intervals: 1.0-8.0 and a hazard ratio of 2.9, 95% confi dence intervals: 1.44-5.88, independently of a previous history of @entity6 and TIMI risk score. CONCLUSIONS: in @entity1 with STEMI, admission @entity4854 is associated with a worse prognosis which was significantly improved with primary angioplasty compared to thrombolysis, independently of the admission TIMI risk score.
