[Prognostic significance of the results of a physical loading test in myocardial infarct patients].
The predictive value of clinical, hemodynamic and electrocardiographic changes in response to an exercise test was assessed with respect to the probability of fatal outcome within 2 years after myocardial infarction (MI). A total of 421 male MI patients were studied; their age averaged 49 +/- 7.7 years. Exercise tests (bicycle ergometry) were carried out 6 to 12 weeks after MI in 364 (86.4%) patients; they were contraindicated to 57 (13.6%) patients. Within 2 postinfarction years, 19 (5.0%) patients died of coronary heart disease in the tested group, and 5 (8.7%) died in the group where the tests were contraindicated. Poor prognosis was associated with low exercise threshold (450 kgm/min for 2 min or less) and horizontal or slanting ST depression. The presence of medical contraindications to exercise tests is as significant with respect to mortality as the low exercise threshold (450 kgm/min for not more than 2 min).
