Регресс субклинического поражения органов-мишеней у больных гипертонической болезнью на фоне различных подходов к назначению комбинированной антигипертензивной терапии
Цель: оценить динамику показателей, характеризующих субклиническое поражение органов-мишеней, на фоне различных подходов к назначению комбинированной антигипертензивной терапии (АГТ) блокаторами ренин-ангиотензин-альдостероновой системы у больных гипертонической болезнью (ГБ). Материалы и методы: обследованы 60 больных ГБ, имеющих субклиническое поражение сердца, по данным состояния коллагенового матрикса миокарда левого желудочка (TIMP-1, CTP-1) без гипертрофии левого желудочка, артерий по показателям объемной сфигмоплетизмографии, почек по уровню микроальбуминурии (МАУ) и скорости клубочковой фильтрации (СКФ) по формуле MDRD. Больные были разделены на 2 равные группы в зависимости от выбора АГТ. Пациенты 1-й группы получали фиксированную комбинацию эпросартана мезилата и гидрохлоротиазида независимо от уровня артериального давления (АД) и сердечно-сосудистого риска (ССР). Во 2-й группе АГТ назначали в зависимости от уровня АД и ССР: монотерапия эналаприлом и нефиксированная комбинация его с гидрохлоротиазидом. Длительность терапии составила 6 мес. Результаты: достоверных различий между группами в достижении целевого уровня АД не выявлено. Регресс субклинического поражения органов-мишеней в 1-й группе больных был более выражен, чем во 2-й группе: по динамике показателей TIMP-1 (p=0,011), скорости пульсовой волны в каротидно-феморальном сегменте (p=0,021), в плече-лодыжечном сегменте (p=0,042), в аорте (p=0,036) независимо от уровня АД (индекс CAVI1, p=0,005), МАУ (p<0,001) и СКФ (p<0,001). Заключение: регресс субклинического поражения органов-мишеней у больных ГБ зависит не столько от достижения целевого уровня АД, сколько от выбора стратегии АГТ в дебюте лечения.
Aim: to evaluate the time course of changes in the parameters characterizing subclinical target organ damage during different approaches to combination antihypertensive therapy (CAHT) with renin-angiotensin-aldosterone system blockers in hypertensive patients. Subjects and methods. Examinations were made in 60 hypertensive patients with subclinical damage to the heart according to the data on left ventricular collagen matrix (TIMP-1, CTP-1) without left ventricular hypertrophy, arteries from volume sphygmoplethysmographic findings, kidneys from urinary microalbumin (UMA) levels and glomerular filtration rate (GFR), by employing the Modification Diet in Renal Disease formula. The patients were divided into two matched groups according to the choice of antihypertensive therapy (AHT). Group 1 patients received a fixed-dose combination of eprosartan mesylate and hydrochlorothiazide regardless of blood pressure (BP) levels and a cardiovascular risk (CVR). In Group 2, AHT was used depending on the level of BP and CVR: monotherapy with enalapril and its non-fixed dose combination with hydrochlorothiazide. The duration of the therapy was 6 months. Results. No significant differences were found between the groups in attaining BP goals. In Group 1, regression of subclinical target organ damage was more pronounced than that Group 2 in terms of TIMP-1 levels (p=0,011), pulse wave velocity in the carotid-femoral (p=0,021) and brachiomalleolar (p=0,042) segments, and aorta (p=0,036) irrespective of BP (CAVI1, p=0,005) and UMA levels (p<0,001), and GFR (p<0,001). Conclusion. Regression of subclinical target organ damage in hypertensive patients depends on the choice of a strategy of AHT at the time of its start rather than on the attainment of BP goals.
Key words: regression of subclinical target organ damage, hypertensive disease, combination antihypertensive therapy.
