Prognostic value of exercise testing: a 6-year follow-up in post-myocardial infarction patients.

The predictive value of a symptom-limited exercise test was studied over a 6-year period in 112 men, who had survived a myocardial infarct. The test was performed within 3 months after the infarct. Among clinical variables, only a history of a previous myocardial infarct seems to bear some prognostic importance. Among the exercise parameters, the development of a ST-segment depression of greater than or equal to 2.0 mm at low effort and the maximal exercise parameters were indicative of future mortality and non-fatal recurrent infarction.
