[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.

[Cardiohemodynamic variants in the development of coronary insufficiency in patients with exercise-induced angina pectoris].

Oxygen requirement and supply (RS) of the myocardium were studied in 232 patients with coronary heart disease during an angina pectoris (AP) attack provoked by bicycle ergometry. It was discovered that an attack of stable AP occurs approximately at the same level of the RS tension in all the functional classes of AP. This level correlates with the RS tension in normal subjects exposed to submaximal exercise.
