[Evaluation of the phase-volume parameters of the left heart ventricle in patients with hypertension and nephrogenic arterial hypertension].

Echocardiographic examination of the phase structure of the cardiac cycle was studied in 41 patients with hypertensive disease (stage II) and 37 patients with the hypertensive variant of chronic glomerulonephritis. The authors revealed a certain characterization of blood filling of the left cardiac ventricle at different phases of diastole in these patients. Thus, in patients with hypertensive disease diastolic relaxation of the left ventricle is compensated by an increase of the volume of blood filling during the phase of slow filling and systole phase of the left atrium while in patients with chronic glomerulonephritis compensation occurs mainly due to increased contribution of the blood filling at the systole phase of the left atrium.
