Influence of dapagliflozin on cardiovascular remodeling in hypertensive patients with accompanying type 2 diabetes
Abstract
Aim. To compare the results of 12-week treatment of patients with stage II hypertension (HTN) with accompanying diabetes mellitus (DM) type 2 between the combination of metformin + dapagliflozin and metformin monotherapy by studying changes in the elastic properties of the common carotid arteries (CCA), echocardiographic indicators, 24-hour ambulatory blood pressure monitoring (ABPM) and laboratory parameters of lipid and carbohydrate metabolism. Materials and methods. 24 patients with stage II HTN with type 2 DM were involved in the study, the average age was 60.4 years, 50 % – men. Patients in the first group were randomized to receive metformin, and the second group – to receive a combination of metformin and dapagliflozin. At inclusion and after 3 months of treatment, basic anthropometric data, laboratory indicators of lipid and carbohydrate metabolism, ABPM, echocardiography, and indicators of CCA local stiffness were studied. Statistical analysis was performed, the probability of differences is at the level of p < 0.05. Results. In both observation groups, there was a comparable decrease in SCORE 2-Diabetes range, glucose and glycated hemoglobin, total cholesterol, LDL cholesterol, average daily systolic blood pressure (SBP), daily SBP load, day and night pulse BP, as well as an increase in speed systolic movement of the lateral fibrous ring of the mitral valve (S lat). Only in the metformin + dapagliflozin group a decrease in the adipose tissue level, the average daily diastolic blood pressure (DBP), the burden of DBP, the size of the left atrium and right ventricle, an increase in the movement speeds of the medial (e’med), lateral (e’lat) ring of the mitral and of the tricuspid (e’tk) valve in the period of early diastolic filling of the ventricles, velocities of systolic movement of the medial fibrous ring of the mitral (S med) and tricuspid (S tk) valves, a decrease in the ratio E/e’, and an improvement in the elastic properties of general carotid arteries were observed. Conclusions. In persons with HTN stage II with DM type 2 the addition of dapagliflozin to the treatment regimen was associated with better control of blood pressure, improvement of diastolic function and longitudinal contractility of the left ventricle, elastic properties of CCA.
