[Cerebral circulatory characteristics in arterial hypertension].
A study was made of the peculiarities of the cerebral circulation with regard to the central hemodynamics in 326 men and 410 women aged 20 to 54 with normal and raised arterial pressure (AP) by the methods of bipolar rheoencephalography and tetrapolar chest rheography. In the groups with raised AP men (women) demonstrated a decrease in the blood pulse inflow in the cerebral arteries up to 57% (36%), in the stroke volume cerebral fraction up to 69% (53%), an increase in the vascular tone up to 137% (161%), an increase in the total blood-filling up to 157% (176%), inhibition of the rate of the maximum blood-filling up to 54% (37%) as compared to that in normal. With the transition of an AP borderline level to arterial hypertension the frequency and intensity of rheoencephalographic pathology was on an increase.
