[Physical exercise in patients with angina pectoris of effort].
Results of physical training in 37 patients with the ischaemic heart disease with angina of effort are given, 31 one them had had myocardial infarction. Training on bicycle ergometer lasted 2 1/2 to 10 months. After exercise 75% of patients showed enhanced threshold capability, the "double product" (the heart rate x systolic AP) decreased at the expense of the pulse deceleration and decrease of the systolic AP with the standard exercise of 50 W. The maximum size of the "double product" under exercise and also with the appearance of angina remained unchanged. The heart volume after exercises did not change. Changes in haemodynamics depended on the initial functional state of the myocardium, which was evaluated by the degree of rise of the diastolic pressure in the pulmonary artery (DPPA) with 50 W exercise and according to the functional curves of the left ventricle traced by comparing DPPA and the minute volume. In patients with "good" myocardial function (DPPA not lower than 30 mm Hg) after exercises the stroke and minute volumes increased with the threshold exercise, DPPA decreased with 50 W, functional curve of the left ventricle approached the functional curve of healthy individuals. Patients with "bad" function (DPPA over 30 mm Hg and higher did not show) changes in haemodynamics and in the functional curve of the left ventricle.
