The aim – to determine prognostic factors of improving left ventricular diastolic function (LV DF) in resistant hypertension (RH) patients (pts) treated with multicomponent antihypertensive therapy during three years.Materials and methods. 102 patients with true RH were included. Patients received triple fixed combination (blocker of the renin-angiotensin-aldosterone system / calcium antagonist / diuretic), to which has been added a fourth drug (spironolactone, eplerenone, moxonidine, torasemide or nebivolol). The state of LV DF was studied at the beginning and at the end of the study. Office and 24-h ambulatory blood pressure (BP) measurements, echocardiography, clinical characteristics, neurohumoral and proinflammatory status were assessed.Results and discussion. Impairment LV DF was detected in 75.5 % of pts. The first degree of LV diastolic dysfunction (DD) was observed in 63.7 %. The patients were divided into 2 groups: the first group included persons without initial impairment of LV DF (n=25), the second – pts with LV DD (n=77). Patients with LV DD were older, had a longer duration of hypertension, higher body mass index, 24-h urinary albumin excretion, office BP and 24-h ambulatory BP, more often (in 2 times) disorders of circadian BP rhythm and concomitant diabetes mellitus (DM). Left ventricular DD in 100 % of cases was associated with severe LV hypertrophy (LVH), increased plasma concentration of inflammatory proteins (CRP, fibrinogen), cytokines (IL-6, TNF-α), increased activity of leukocyte elastase, macrophage matrix metalloproteinase-12. The concentration in the blood of aldosterone, active renin, 24-h urinary excretion of metanephrines did not differ between the groups.Conclusions. Improvement and stabilization of LV DF occurred in parallel with regression of LVH (normalization of LVMI in 35.1 % of pts and significant decrease of LVMI in 64.9 %) against the background of decrease of BP and in the proportion of pts with disturbed circadian BP rhythm. The independent factors of the E/E’ ratio were the initial plasma concentrations of aldosterone (β=0.556; р=0.0001), glucose (β=0.366; р=0.0001), active renin (β=–0.223; р=0.004), 24-h urinary albumin excretion (β=0.188; р=0.016), age (β=0,192; р=0,023). The odds of an improvement in LV DF increased by 3.7 times, if the patient with RH had no DM, LVH regression occurred.
