[The cardiovascular system in patients with chronic renal failure (echocardiographic data)].

Based on the study of the echocardiography data in 44 patients with chronic renal failure it has been shown that the incidence and the degree of left ventricle hypertrophy is related to the duration of arterial hypertension, increased cardiac output, and metabolic abnormalities. Echocardiographic studies made over time revealed a progressive deterioration of myocardial contractility. Pericarditis that ensues promotes the deterioration of left ventricle contractility and aggravates heart insufficiency. The diastolic murmur of aortal regurgitation should be differentiated as pertaining to infectious endocarditis or to relative insufficiency of the aortal valve. Two-dimensional echocardiography favours differentiation of left ventricle myocardial hypertrophy, makes it possible to locate the fluid in the pericardium more accurately, and to evaluate the treatment efficacy for pericarditis.
