[Hemodynamics in patients with circulatory insufficiency depending on the activity of the rheumatic process]

In 384 rheumatic patients, including 344 with mitral defect of the heart central hemodynamics, phasic structure of the left ventricle systole and renal hemodynamics were studied. With the help of the sought out algorythm and the computer technique qualitative information on the activity of the rheumatic process, expressed in terms of plausability proportions for each patient, was obtained. This was followed by a search for a correlation between the values of these proportions and the parameters of the cardiac function. An inverse correlation was found only relative to the stroke index and the ejection rate and merely in patients with mitral defect and circulatory insufficiency of the IIB-III stage. No essential difference was found between the values characterizing the hemodynamics, the duration of the left ventricle systole phases recorded in the groups of patients with active and inactive rheumatism, but at equal stages of ciruclatory insufficiency.
