The influence of being overweight or @entity28 on hospital and late (1 year) mortality and reinfarction was studied in 1760 @entity1 with @entity583 . Body mass index (BMI) was used to categorize @entity1 as normal weight (BMI less than 25), overweight (BMI 25 to 30), and @entity28 (BMI greater than 30). Clinical features and prognosis were compared in 658 normal weight @entity1 , 884 overweight @entity1 , and 218 @entity28 @entity1 . Complications during hospitalization and 1-year reinfarction rates following discharge were similar among the weight subsets. Hospital mortality was 13% in @entity28 @entity1 , similar to the 14% hospital mortality in normal weight @entity1 , but significantly more than that in overweight @entity1 (9%, p less than 0.05). When stratified according to age, 30% of @entity28 @entity1 greater than or equal to 65 years died in the hospital, compared to 13% of overweight @entity1 (p less than 0.001), and 17% of normal weight @entity1 (p less than 0.01). In @entity1 less than 65 years, the @entity28 group had a 6% mortality compared to a hospital mortality of 5% in overweight and 8% in normal weight groups (NS). In a multivariate analysis, @entity28 was an independent predictor of @entity204 in the older, but not in the younger @entity1 subset. One-year mortality for @entity1 discharged from the hospital was significantly less in @entity28 than in normal weight @entity1 (7% vs 13%, p less than 0.05), but not different from the 11% mortality rate in overweight @entity1 . Differences in mortality disappeared when @entity1 were age stratified.(ABSTRACT TRUNCATED AT 250 WORDS)
