Органопротективный эффект фиксированной комбинированной антигипертензивной терапии эпросартаном и гидрохлоротиазидом при субклиническом и клиническом поражении органов-мишеней у пациентов с гипертонической болезнью
Цель исследования – оценка влияния фиксированной комбинированной антигипертензивной терапии эпросартаном и гидрохлоротиазидом со старта на клинические и субклинические показатели поражения органов-мишеней у пациентов с гипертонической болезнью (ГБ) независимо от исходного уровня артериального давления (АД) и сердечно-сосудистого риска. Материалы и методы. Исследование представляет два параллельных субисследования. В первом субисследовании при скрининге 3536 рабочих промышленного предприятия выявлены 13,0% (395 человек) больных ГБ. Среди них зарегистрированы 12,7% (50 человек) нелеченых больных ГБ, имеющих трехкомпонентное поражение органов-мишеней: гипертрофию левого желудочка, гипертоническую нефропатию, поражение периферических артерий. Во втором субисследовании среди той же когорты были зарегистрированы 15,2% (60 человек) нелеченых больных ГБ I стадии без клинических признаков органных изменений. 1-я группа в обоих субисследованиях получала фиксированную комбинацию эпросартана мезилат в дозе 600 мг и гидрохлоротиазида в дозе 12,5 мг 1 раз в сутки независимо от исходного уровня АД в дебюте исследования. 2-й группе назначалась монотерапия эналаприлом и/или в комбинации с гидрохлоротиазидом в зависимости от степени повышения АД и группы сердечно-сосудистого риска. Результаты. Комбинированная фиксированная антигипертензивная терапия (эпросартан + гидрохлоротиазид) со старта независимо от исходного уровня АД и сердечно-сосудистого риска в сравнении с монотерапией эналаприлом и/или его свободной комбинацией с гидрохлоротиазидом, назначаемой с учетом уровня АД и сердечно-сосудистого риска, обеспечила более выраженный регресс как клинического, так и субклинического поражения органов-мишеней на фоне 6-месячной терапии по данным динамики массы миокарда левого желудочка (ММЛЖ), индекса ММЛЖ и тканевого ингибитора матриксных металлопротеиназ 1-го типа, микроальбуминурии и скорости клубочковой фильтрации, толщины комплекса интима–медиа при выполнении допплерографического ультразвукового исследования сонных артерий и показателей скорости пульсовой волны в разных сегментах по результатам объемной сфигмоплетизмографии. Выводы. Назначение фиксированной комбинации эпросартана и гидрохлоротиазида нелеченым больным ГБ трудоспособного возраста со старта независимо от исходного уровня АД и сердечно-сосудистого риска обеспечивает регресс поражения органов-мишеней и профилактику их развития при отсутствии органных изменений.
Ключевые слова: гипертоническая болезнь, поражение органов-мишеней, фиксированная комбинация эпросартана мезилата и гидрохлоротиазида.

Aim: to evaluate the efficiency of starting fixed-dose combination therapy with eprosartan and hydrochlorothiazide on the clinical and subclinical parameters of target organ damage in patients with hypertensive disease (HD) irrespective of baseline blood pressure (BP) and cardiovascular risk. Subjects and methods. The study consisted of two parallel substudies. Substudy 1 that screened 3536 workers from industrial enterprises identified 395 (13%) hypertensive patients. Among them, there were 50 (12,7%) untreated patients with HD who had three-component target organ damages: left ventricular hypertrophy, hypertensive nephropathy, peripheral artery lesion. Sixty (15,2%) untreated patients with Stage 1 HD without clinical signs of organ changes were recorded among the same cohort in Substudy 2. In both substudies, Group 1 received a fixed-dose combination of eprosartan mesylate 600 mg once daily and hydrochlorothiazide 12,5 once daily regardless of baseline BP at the onset of the study. Group 2 had monotherapy with enalapril and/or its combination with hydrochlorothiazide depending on the degree of BP elevation and the group of a cardiovascular risk. Results. Starting fixed-dose combination antihypertensive therapy (eprosartan + hydrochlorothiazide) irrespective of baseline BP and cardiovascular risk versus monotherapy with enalapril and/or its free combination with hydrochlorothiazide, which was used in terms of BP level and cardiovascular risk ensured a more significant regression of both clinical and subclinical target organ damages during 6-month therapy according to the changes in left ventricular mass (LVM), LVM index, and tissue inhibitor of type 1 matrix metalloproteinases, microalbuminuria and glomerular filtration rate, intima-media complex thickness during carotid Doppler ultrasound study, and pulse wave velocity in different segments, as evidenced by volumetric sphygmoplethysmography. Conclusions. The use of a fixed-dose combination of eprosartan and hydrochlorothiazide in untreated patients of able-bodied age regardless of baseline BP and cardiovascular risk ensures the regression of target organ damages and the prevention of their development in the absence of organ changes.
Key words: hypertensive disease, target organ damage, fixed-dose combination of eprosartan mesylate and hydrochlorothiazide.
