Effectiveness of a fixed combination of empagliflozin with metformin in reduction of cardiovascular risk in patients with uncontrolled arterial hypertension and decompensated type 2 diabetes mellitus

Objective is to study the effectiveness of a fixed combination of empagliflozin and metformin in reducing cardiovascular risk in patients with uncontrolled arterial hypertension (AH) and decompensated type 2 diabetes mellitus (DM). Materials and methods. 36 patients with uncontrolled AH and decompensated type 2 diabetes mellitus aged 45 to 60 were examined. Before inclusion in the study, all patients received standard antihypertensive (angiotensin‑converting enzyme (ACE) inhibitor or angiotensin‑II receptor blocker (ARB) in combination with a calcium channel blocker and a thiazide‑like diuretic), glucose‑lowering (metformin) and hypolipidemic (atorvastatin) therapy. However, target levels of blood pressure (BP), glycated haemoglobin (HbA1c) and lipids were not achieved. After the initial examination, all patients were prescribed a fixed combination of empagliflozin and metformin at a dose of 12.5 mg/1000 mg 1—2 times a day, and antihypertensive and hypolipidemic therapy was continued. Re‑examination was carried out after 20 weeks. In the work, a statistical analysis of the obtained data was carried out using standard methods using Microsoft Excel 7.0 and SPSS 19.0 application packages. Results. The transfer of the examined patients from previous ineffective hypoglycemic therapy to a fixed combination of empagliflozin with metformin against the background of standard antihypertensive and hypolipidemic therapy made it possible to achieve the target levels of HbA1c in 69% of patients and target BP levels in 64%. The frequency of reaching target BP levels in the subgroup of patients who received ARB was significantly higher than in the subgroup of patients who received ACE inhibitors. The specified therapy contributed to a significant reduction in body weight, reaching the target levels of low‑density lipoprotein cholesterol (LDL‑C) and non‑high‑density lipoprotein cholesterol (Non‑HDL‑C) in more than a third of patients, and reducing the severity of albuminuria in some patients. The tested therapy, in general, led to reduction in cardiovascular risk and did not cause side effects that could lead to discontinuation of treatment. Conclusions. The fixed combination of empagliflozin with metformin against the background of standard antihypertensive and hypolipidemic therapy in patients with uncontrolled hypertension and decompensated type 2 diabetes mellitus contributed to the achievement in the vast majority of patients of the target levels of HbA1c in the blood and BP levels, reduced body weight, positive changes in lipid metabolism and kidney function, and demonstrated the possibility of a significant reduction in cardiovascular risk. A more pronounced decrease in BP was detected in the case of a fixed combination of empagliflozin and metformin with ARB compared to ACE inhibitors in this category of patients.
