[Dynamics of electrocardiographic, cardiohemodynamic and biochemical indices as affected by intensive bicycle ergometer training in stenocardia patients].
Intensive training in patients with IHD suffering from attacks of angina pectoris helps to enhance tolerance to exercise and to increase the volume of the work performed. In response to the threshold exercise the degree of pathological displacement of ST segments on ECG diminishes and in 34% of patients with the initial signs of coronary insufficiency the ECG parameters return to normal. The cardiohaemodynamic picture points to the economical activity of the cardiovascular system in performing "preischaemic" exercise and to the improvement of the reaction both at the expense of exercises. This supervenes both at the expense of the improved contractile function of the myocardium in the presence of activation of aerobic glycolysis and also through decreased peripheral vascular resistance. The training gives best effect with its timely use in subjects with the initial manifestations of coronary insufficiency.
