[Central hemodynamics during long-term physical training of patients after myocardial infarction]
Abstract:
Left-ventricular function under the effect of regular exercise was examined in post-infarction patients. Ultrasonic B-scanning technique was used to investigate 49 patients doing regular exercise and 34 control patients. The duration of an exercise course was 9-9.5 months. It was demonstrated that long-term physical training resulted in favourable changes in terms of left-ventricular propulsive capacity, whereas control patients showed deterioration of their pumping and contractile functions. The results are vet another evidence that the effect of exercise is necessarily mediated by the heart as the central link of circulation.
