Renal haemodynamics in hypertensive patients and its change with treatment with hexamethon and reserpine

Studies of renal hemodynamics show that the effective renal blood flow is impaired sometimes in the earliest phases of the disease (Ratner, 1953; Kireev, 1954; Chizhikov, 1955; Ratner, 1959; Leontieva, 1962, etc.). Some authors believe that the blood flow is disturbed due to BP increase (N.A. Ratner), others do not find such a connection (M.Y. Ratner, H.S. Leontieva). We monitored effective renal blood flow and total renal resistance in 65 hypertensive patients before treatment, and in 56 patients these data were compared with the results obtained after treatment with hexamethon in combination with reserpine.
