The incidence and the prognostic value of exertional hypotension was studied in 488 consecutive patients admitted to the Montescano Rehabilitation Center after acute myocardial infarction. During a symptom-limited bicycle ergometric test performed 28 to 60 days after acute myocardial infarction 33 patients (6.8%) showed exertional hypotension. These patients were grouped according to effort S-T segment modifications: Group A (n = 13) with S-T segment depression in ECG-leads without Q waves; Group B (n = 11) with S-T segment elevation in leads where Q waves were present; Group C (n = 9) with no exercise S-T changes. Group B patients had a larger infarct size by ECG criteria and a lower maximal work capacity at the functional stress test. The follow-up of the patients after discharge was 28.3 +/- 13.2 months. During rehabilitation and follow-up, 2 patients of Group B died and 5 suffered an acute pulmonary oedema; 3 patients of Group A and 1 of Group B had angina at rest. Group C patients had no complications. Thus, exertional hypotension and S-T elevation appear to be predictive of future cardiac event.
