ЭНДОТЕЛИЙ – ОРГАН-МИШЕНЬ ТЕРАПЕВТИЧЕСКОГО ВОЗДЕЙСТВИЯ У ЖЕНЩИН С АРТЕРИАЛЬНОЙ ГИПЕРТОНИЕЙ НА ФОНЕ ЭСТРОГЕНОВОГО ДЕФИЦИТА

Purpose. To study the endothelial function in the onset of arterial hypertension (AH) in perimenopausal women and to evaluate the possibility of the influence of antihypertensive therapy on endothelial dysfunction. Materials and methods. The study included 81 patients with essential hypertension (EH) I–II stage of 1–2 degrees and 23 healthy perimenopausal women. The level of estradiol and follicle stimulating hormone (FSH) were analyzed. Endothelial function was assessed by endothelium-dependent (EDVD), endothelium-independent (ENVD) vasodilation of the brachial artery and laboratory markers. Results. Regardless of the AH stage and degree 50 % of patients had endothelial dysfunction by EDVD / ENVD and vasoconstriction endothelial markers (endothelin-1 (ET-1), asymmetric dimethylarginine (ADMA)) were increased. 12 weeks of treatment showed a statically significant reduction (p<0,05) in the concentration of ET-1 and ADMA, and increasing NO production (p<0,05) in all patients with hypertension. Conclusion. Perimenopausal women with EH regardless of the stage and degree blood pressure had a violation of EDVD/ ENVD and a change of endothelial markers. Monotherapy blockers of the renin-angiotensin-aldosterone system (RAAS) showed blood pressure normalisation and endothelial function improvement in most women with AH stage I-II and 1 degree, with 2 degree required a combination therapy with the addition of bisoprolol and low doses of hydrochlorothiazide to RAAS.
