Abstract

A hypotensive effect of corinfar and its effect on the indices of the central and peripheral hemodynamics were studied in 50 patients with stage II hypertension. In 3 weeks BP was lowered at the expense of a considerable decrease in the total peripheral vascular resistance (TPVR) (by 29.6%) and regional vascular resistance (by 48%). It was accompanied by an increase in the peripheral blood flow (by 61%), a reflex activation of the sympathetic-adrenal system with an increase in heart rate and cardiac output (by 22%, p less than 0.001). An index of vein distensibility remained unchanged. The addition of propranolol removed signs of the sympathetic stimulation of the cardiac activity, improved vasodilatator tolerance, enhanced a hypotensive effect of corinfar causing a transient increase in TPVR and tension of the resistive vessels only. By the end of the 4th month of therapy these indices significantly decreased. A prolonged combined therapy with corinfar and propranolol resulted in a significant decrease in the resistance of resistive vessels in maximum vasodilatation characterizing the regression of arteriole structural changes. Besides there was a decrease in the wall thickness (p less than 0.01) and left ventricular myocardia...Continue Reading
