[The evolution of hospital mortality due to acute myocardial infarct in the first 2 GISSI studies. Participants in the GISSI 1 and GISSI 2 studies. Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto Miocardico].
During the short while of 5 years, between 1984 and 1985, two large clinical trials have been performed in Italy concerning fibrinolytic therapy in Acute Myocardial Infarction: GISSI 1 and GISSI 2. They made possible to evaluate the evolution of demographic and clinical features, the in-hospital mortality rate, and the causes of death of a huge number of patients admitted to CCU throughout the whole country. Out of 31,826 patients with acute myocardial infarction admitted to 176 CCU participating to the GISSI 1 16.9% were 75 years old and 24.7% were females; 21.8% and 26.4% were the percentages in the 38,086 patients admitted to the 223 CCU participating in the GISSI 2. ⋯ As a matter of fact 468 patients died of the 4,696 (10.0%) treated with SK in the GISSI 1 against 1,092 patients of 12,381 (8.8%) enrolled in the GISSI 2 and treated with SK or rtPA (RR 0.87; L. C. 0.78-0.98). The reduction of in-hospital mortality may be explained by some differences in the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)
