Differences in the effects of various classes of antihypertensive drugs in combination therapy on indicators of arterial hemodynamics, vascular wall stiffness and structural-functional state of heart in patients with arterial hypertension of 1 — 2 degrees

The aim —  to compare the effect of 6‑month treatment of patients with arterial hypertension (AH) of 1 — 2 degrees with angiotensin converting enzyme (ACE) or angiotensin II receptor blockers (ARB) in combination with a thiazide diuretic (indapamide) and dihydropyridine calcium channel blockers (CCB) in combination with a diuretic on indicators of brachial and central arterial pressure (AP), elastic properties of the arteries and the structural and functional state of the heart, depending on age. Materials and methods. The study included 320 patients (156 men and 164 women) aged from 35 to 80 years (mean age 62.8 ± 0.61 years) with uncomplicated AH of stage I — II, degree 1 — 2 (62.0 % and 38, 1 %, correspondingly). Depending on age, the patients were divided into two groups:   0.05). In both subgroups of patients aged   0.05). In the group treated with Arifam , the baseline HR values correlated with AP (r = –0.357, p   0.05). In patients aged ≥ 65 years, the antihypertensive effect of therapy with the combination of ACE inhibitor/ARB and indapamide was not accompanied by changes in MMI LV and indicators of LV systolic and diastolic function (all p > 0.05). In the group treated with Arifam there was a decrease in end‑diastolic and end‑systolic volumes (by 9.7 % (p   0.05). Conclusions. In spite of the same positive effect of 6‑month therapy with combinations of ACE inhibitors/ARB with indapamide and BPC with indapamide on brachial and central AP in older patients with hypertension of 1 — 2 degrees, the fixed combination of BPC amlodipine with indapamide ( Arifam ) had an advantage over the combination based on an ACE inhibitor (ARB) regarding the reduction of brachial, central, mean brachial and mean central AP, augmentation, pulse wave velocity, MMI of LV, left atrium volume index, E/e’ of LV, which was associated with an increase in heart rate (an average of 4.6 per 1 min).
