Structural-functional peculiarities of peripheral hemodynamics in young women with idiopathic arterial hypotension

Introduction and purpose of the work. Peripheral blood circulation in arterial hypotension is poorly understood. The results of the available data are contradictory. The aim of the study was to evaluate the structural and functional parameters of peripheral arteries and veins in idiopathic arterial hypotension in young women. Materials and methods. 72 women with idiopathic arterial hypotension and SBP level of less than 98 mm Hg at the age of 18-22 years were examined. Results were compared with the blood flow parameters of 37 women of similar age with normal arterial pressure (SBP 120-129 mm Hg). During angioscanning, the diameter and velocity indices of the blood flow of the vertebral, brachial, radial, posterior tibial arteries and the respective veins were studied. Results. A decrease in blood flow rate in the brachial and posterior tibial arteries, as well as in the brachial and posterior tibial veins was revealed. Differences in diameters of arteries and veins between women of the two groups were not revealed. Conclusions. Idiopathic arterial hypotension (SBP < 98 mm Hg) in young women is characterized by a lower blood flow rate in the peripheral arteries and veins than in women with normal arterial pressure.
