Identification of high-risk subgroups of @entity1 after @entity583 ( @entity583 ) is essential for evaluation of targeted preventive strategies. A case-control study was performed in 250 post- @entity583 @entity1 to examine whether an episode of @entity2224 ( @entity2224 ) during the in-hospital period modifies the long-term prognosis for @entity1 with either an anterior or an @entity4156 . After identification of 70 @entity1 with an anterior @entity583 and 55 @entity1 with an @entity4156 , all complicated by @entity2224 and discharged alive, we selected 125 additional @entity1 who had an @entity583 not complicated by @entity2224 (control subjects). To minimize the potential sources of differences in outcome, cases and controls were matched for the following variables: sex (all @entity1 ), age (same +/- 2 years), coronary care unit (same), epoch of @entity583 (same +/- 3 months), and site of @entity583 (same). @entity1002 and prior @entity583 were present in only a few @entity1 . @entity1 receiving either acute or long-term treatment with beta-adrenergic blocking agents were not included. The average follow up was 59 months (range 12 to 120). The cumulative mortality during the first 5 years for the @entity1 with @entity4156 without @entity2224 (6%, 11%, 13%, 13% and 13%) was modest and not significantly different from that of @entity4156 complicated by @entity2224 (6%, 11%, 20%, 20%, and 26%). In contrast, a striking difference appeared when the cumulative mortality of @entity1 with anterior @entity583 without @entity2224 (9%, 13%, 17%, 27%, and 29%) was compared with that of @entity1 with anterior @entity583 complicated by @entity2224 (32%, 40%, 46%, 49% and 54%) (p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)
