[On the connection between left ventricular hypertrophy and diastolic dysfunction in arterial hypertension].

Aim: To evaluate relationships between arterial pressure (AP), myocardial mass of the left ventricle (LVMM) and left ventricular diastolic function (LVDF) in patients with hypertension stage I and II.

Material And Methods: 89 hypertensive patients and 30 healthy subjects (control group).

Results: Initial defects in LVDF in the absence of its hypertrophy were detected already in hypertension stage I.

[Prognostic significance of ECG changes in acute pneumonia].

A total of 293 patients with acute pneumonia were examined for the relationship between ECG changes and the gravity and immediate outcomes of disease. The pneumonia gravity was determined by the mathematic method based on the computation of the prognostic index of pneumonia (Z. K.

[Effect of isoptin on the central and peripheral hemodynamics in hypokinesia in healthy persons].

Central and peripheral hemodynamics was studied by the radioisotope method employing 131I-labelled albumin, the blood flow in the muscles was investigated (using 133Xe) and the longitudinal rheovasogram of the leg and forearm recorded in 10 healthy male volunteers before, during, and after 45-day antiorthostatic hypokinesia. Five of the examines received isoptin, while the remaining 5 formed the control group. Due to the effect of hypokinesia a tendency towards a a decrease in the circulation volume, a reduced stroke index, an increase in the central venous pressure and peripheral resistance, and a decrease in the muscular blood flow were observed.
