[The characteristics of disorders of intracardiac hemodynamics and hemorheology in pulmonary heart failure].
Overall ninety patients with chronic obstructive bronchitis presenting with signs of varying degree cardiopulmonary insufficiency (CPI) were evaluated by radionuclide ventriculography with technetium pertechnetate as well as by rotational viscosimetry of blood. The degree of hemorheological derangements tended to get higher with CPI severity (light, moderately severe, severe) being accompanied by progressing impairement of systolic and diastolic functions of both ventricles of the heart. Mechanisms of compensation of endocardiac hemodynamics were realized as a result of increase in end-diastolic and end-systolic volumes of both ventricles together with changes in amplitude and time characteristics of processes of ventricular ejection and filling. Forecast of the probable course of the condition may rely upon the functional state of right as well as left ventricle of the heart.
