We examined whether or not subsets of @entity1 with complex @entity943 after @entity583 are at high risk with respect to 1 year mortality after hospital discharge. Based on previous studies showing increased risk for those with non-Q wave @entity1188 , we hypothesized that complex @entity1540 ( @entity1540 ) in this group might be associated with a poorer prognosis than complex @entity1540 in @entity1 with Q wave @entity1188 . Seven hundred seventy-seven @entity1 entering our study with acute @entity1188 were followed prospectively for 1 year after undergoing a predischarge 24 hr ambulatory electrocardiographic examination. @entity1 were classified by electrocardiographic criteria into the following groups: Non-Q wave (n = 191), Q wave anterior (n = 261), and Q wave inferior @entity1188 (n = 325). The following @entity943 were classified as complex: multiform @entity1540 , couplets, and @entity1165 . Sixty-two percent of @entity1 with non-Q wave @entity1188 who did not survive 1 year had complex @entity1540 , compared with 32% of survivors (p less than .01). No differences were seen in the Q wave subgroup. The survival for @entity1 with Q wave and non-Q wave @entity1188 without complex @entity1540 were nearly identical at 1 year (93% and 90%), whereas in @entity1 with complex @entity1540 survival for those with Q wave and non-Q wave @entity1188 was 92% and 76%, respectively (p less than .001). Of those with non-Q wave @entity1188 , only 4% of nonsurvivors were free of any @entity1540 , as compared with 28% of nonsurvivors in the Q wave group (p less than .02).(ABSTRACT TRUNCATED AT 250 WORDS)
