[Repeated veloergometric tests in the hospitalization period of myocardial infarction].

Bicycle ergometry and echocardiography were conducted in 54 patients with primary uncomplicated large-focal myocardial infarction (MI), while their central hemodynamic parameters were examined radiocardiographically on days 10, 20 and 30 of the disease. About 70% of patients were doing exercise until they were fatigued or showed a submaximum pulse rate, whereas 20% developed angina pectoris. In the course of recovery, threshold capacity increased in most of the patients and as the cumulative group result (with a 16% increment from day 10 to day 20).

[Physical training 2 months after myocardial infarct].

Two months after myocardial infarction, 30 patients were subjected to a 10-week physical training course. Following the training, their threshold capacity grew by 46%. The effect of training (increased threshold capacity, reduced double product at submaximum effort) persisted for 1 year after myocardial infarction.
