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.
给出了37例患有劳力性心绞痛的缺血性心脏病患者的体育训练结果，其中31例曾发生过心肌梗死。在自行车测力计上的训练持续2.5至10个月。运动后，75%的患者表现出阈值能力增强，“双乘积”（心率×收缩压）下降，这是由于脉搏减速以及在50瓦标准运动时收缩压降低所致。运动时以及出现心绞痛时“双乘积”的最大数值保持不变。运动后心脏容积未改变。血流动力学变化取决于心肌的初始功能状态，这是通过在50瓦运动时肺动脉舒张压（DPPA）的升高程度以及根据通过比较DPPA和每分容量描绘的左心室功能曲线来评估的。在心肌功能“良好”（DPPA不低于30毫米汞柱）的患者中，运动后每搏量和每分容量随着阈值运动而增加，50瓦运动时DPPA降低，左心室功能曲线接近健康个体的功能曲线。功能“不良”（DPPA超过30毫米汞柱及更高）的患者未表现出血流动力学和左心室功能曲线的变化。
