The aim of the study was to study a vascular reaction to a test with reactive hyperemia in young women with idiopathic arterial hypotension. 72 women with hypotension (SBP 98 mmHg or less) and 37 women with SBP 120-129 mmHg were examined. A comparative analysis of the response of systemic and peripheral hemodynamics to a test with reactive hyperemia by Celermajer D. In hypotension, occlusion was characterized by an increase in SBP, a change in the diameter and velocity of peripheral arterial and venous blood flow. Thus, the pathological reaction of systemic and peripheral hemodynamics in reactive hyperemia in women with hypotension is a sign of remodeling of the cardiovascular system.

Aim. To study the response of peripheral vessels hemodynamics to apnea in young women with idiopathic arterial hypotension. Materials and methods. Comparative analysis of the results of ultrasonic scanning of peripheral arteries and veins using apnea test between 19 women with idiopathic arterial hypotension - SAP 98 (92-98) mm Hg and 11 women with normal arterial pressure - SAP 124 (121-126) mm Hg was carried out. Women’s age in both groups was 18-25 years. Arterial pressure and peripheral oxygen saturation were measured. Angioscanning in lying position and at rest as well as angioscanning prior to and 20 seconds after breath-holding was fulfilled. Diameter and blood velocity were estimated in the brachial, radial and posterior tibial arteries and veins. Results. Apnea in young hypotensive women was found to induce increase in the diameter of a larger number of arteries than in the control group and fall in arterial blood velocity with the absence of venous blood velocity dynamics. Conclusions. The abovementioned changes in the peripheral blood flow among women with hypotension are to be considered as manifestation of deadaptation, expressed by extreme endothelium-dependent dilatation of resistive vessels and inhibition of vasotonic response, probably, associated with excessive nitric oxide endothelial production.
