[Cardiohemodynamic indices during the physical loading of patients with stenocardia of varying duration].

A total of 232 CHD patients and 93 healthy persons were examined to reveal a possible role of the vasospastic and cardiohemodynamic factor in the pathogenesis of angina pectoris of various duration. Cardiohemodynamics, ECG, PCG and tetrapolar chest rheography were studied during a bicycle ergometry test. Two types of cardiohemodynamic reactions in anginal pain were defined: adequate--with low indices characterizing demand of the myocardium for oxygen and sufficient diastole (demand--supply) and inadequate--with an unusually high (1.
