[Radiocardiographic evaluation of the hemodynamics in combined acquired heart defects].
One hundred and twenty eight subjects were examined, 77 of them with acquired combined valvular defects, with an average age of 42,2 as well as 51 healthy subjects. Depending on the degree of cardiac insufficiency, the patients were grouped into three stages, I, II A and II B. The hemodynamics was studied by quantitative radiocardiography. Indices, characterizing the heart pump function, the intracardial transit time, pulmonary circulation, etc. were followed up. The data obtained from the follow up of more than 20 parameters reveal that insignificant hemodynamic disorders develop during the initial stage of compensation and subcompensation of the cardiovascular system. In case of cardiac insufficiency, stages II A and II B the values of cardiac output was markedly and progressively decreased, the intracardial transit times were prolonged, the values of pulmonary circulation and those of the peripheral hemodynamics were considerably increased.
