Эндотелий - орган-мишень терапевтического воздействия у женщин с артериальной гипертонией на фоне эстрогенового дефицита

Abstract

Цель исследования. Изучить функциональное состояние эндотелия у женщин с дебютом артериальной гипертонии (АГ) в перименопаузальном периоде и оценить возможность влияния на эндотелиальную дисфункцию современной антигипертензивной терапии. Материалы и методы. В исследование включены 81 пациентка с гипертонической болезнью (ГБ) I-II стадии 1-2 степени и 23 практически здоровых женщины в перименопаузе. Исследовали уровень эстрадиола и фолликулостимулирующего гормона (ФСГ). Функцию эндотелия оценивали по эндотелий-зависимой (ЭЗВД), эндотелий-независимой (ЭНВД) вазодилатации плечевой артерии и лабораторным маркерам. Результаты. Независимо от стадии ГБ и степени АГ у 50% пациенток была выявлена дисфункция эндотелия по ЭЗВД/ЭНВД а также отмечено повышение эндотелиальных маркеров вазоконстрикции эндотелина-1 (ЭТ-1), асимметричного диметиларгинина (АДМА). Через 12 недель лечения отмечено достоверное снижение концентрации ЭТ-1 и АДМА и повышение продукции NO у всех пациенток с АГ. Заключение. У женщин в физиологической перименопаузе независимо от стадии ГБ и степени повышения АД отмечалось нарушение ЭЗВД и ЭНВД, а также изменение эндотелиальных маркеров. У пациенток с ГБ I-II стадии, 1 степени для нормализации АД и улучшения функционального состояния эндотелия в большинстве случаев была достаточна монотерапия блокаторами ренин-ангиотензин-альдостероновой системы (РААС), при 2 степени требовалась комбинированная терапия РААС с добавлением бисопролола в сочетании с низкими дозами гидрохлортиазида.

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.
