[Predicting the efficacy of rehabilitation in patients with prior myocardial infarction]

The results of a 2-year follow-up of 400 patients with prior myocardial infarction (MI) and bicycle ergometric findings of intracardiac hemodynamic parameters and oxygen supply during exercise tests, and the criteria for tetrachoric index significance within the confidence intervals were used to reveal the factors predicting the efficacy of rehabilitative treatment. To predict decreased working capacity in the long-term period is determined by the extent of lesion after myocardial reinfarction, while angina pectoris and arterial hypertension are of significance in patients without reinfarction. A role of dynamic indices was defined in predicting decreased working capacity. Further lowered working capacity may be judged from the changes occurring in threshold exercise capacity and left ventricular end-diastolic volume in the first 6 months of postinfarction.
