Prognostic significance of exercise testing three weeks after myocardial infarction.

Treadmill exercise test was performed in 50 patients aged 35-60 years, 3 weeks after myocardial infarction. Thirty-two had anterior and 18 had inferior wall transmural myocardial infarction. Cardiac events like angina, reinfarction and sudden death were more common in patients with positive stress test. Thus treadmill testing in the early postinfarction period is of great prognostic value.
