[Indices of intracardiac hemodynamics and of myocardial contractile function in relationship to the total coronary artery lesion in stenocardia].

Study of the intracardiac hemodynamics, the work of the ventricles, and the findings of a phase analysis of the ventricular systole in various groups of patients with angina pectoris showed that the advancement of the atherosclerotic process in the coronary arteries is attended with disorders of contractile properties and with changes in the electromechanical activity of the cardiac muscle. Appraisal of the hemodynamic disorders according to the extent of involvement of the coronary arteries showed that maximum affection of the vessels is attended with marked abnormalities of hemodynamics. A similar regularity was found in analysis of the indices characterizing the contractile function of the myocardium.
