The predictive value of a predischarge symptom-limited stress test was studied in 405 consecutive survivors of @entity583 ( @entity583 ). Three hundred @entity1 performed bicycle ergometry; 105 could not perform it. Among these latter 105 @entity1 , the stress test was contraindicated in 43 because of angina or @entity712 and in 62 because of noncardiac limitations. One-year survival was 44% in the "cardiac-limited" group (19 of 43) and 92% in the "non-cardiac-limited" group (57 of 62). One-year survival among the @entity1 who performed an exercise test at discharge was 93% (280 out of 300). The best stress test predictor of mortality by univariate analysis was the extent of blood pressure (BP) increase: 42 +/- 24 mm Hg in 280 survivors vs 21 +/- 14 mm Hg in 20 nonsurvivors (p less than 0.001). Among the 212 @entity1 in whom BP increased 30 mm Hg or more, mortality was 3% (n = 6), while it was 16% (n = 14) among the 88 @entity1 in whom BP increased less than 30 mm Hg. @entity951 , ST changes and @entity943 were not as predictive. Stepwise discriminant function analysis showed inadequate BP increase to be an independent predictor of mortality. A high-risk group can be identified at discharge on clinical grounds in @entity1 unable to perform a stress test, whereas intermediate- and low-risk groups can be identified by the extent of BP increase during exercise.
