Aim. Evaluation of the safety, clinical and hemodynamic effects of empagliflozin in patients with acute decompensated heart failure (ADHF) from the first day of hospitalization in the absence of signs of hemodynamic instability.Material and methods. A prospective, comparative, randomized study included 46 patients admitted to the hospital in connection with ADHF in the absence of signs of hemodynamic instability. Inclusion in the study and randomization to receive empagliflozin was carried out in the first 24 hours from the moment of admission to the hospital. The main group (n=23) from the first day of hospitalization and the entire subsequent follow-up period took empagliflozin at a daily dose of 10 and 25 mg (for patients with type 2 diabetes mellitus) in addition to basic therapy, the control group (n=23) received standard therapy without gliflozines. The observation period was 3 months and included 3 control points: 1st day of hospitalization, 7th-12th day, 3rd month of observation. Clinical, anamnestic and instrumental data were evaluated at all control points.Results. In the hospital period, by the 7th-12th day, only in the main group there was an improvement in all clinical indicators (p<0.01), an increase in the rate of diuresis (p><0.01), a decrease in the daily dose of the parenteral diuretic furosemide from 54 mg to 26 mg (p><0.01). A decrease in systolic blood pressure (SBP) occurred in both groups (p><0.01), but it was more pronounced in the comparison group [from 141 (110; 160) to 110 (90; 120) mm Hg) compared to the main group [from 140 (120; 160) to 120 (110; 130) mm Hg]. According to echocardiography data in the main group, there was a decrease in the indexed volume of the right atrium, the end-systolic volume of the left ventricle (LV ESV) and systolic pressure in the pulmonary artery, an increase in the LV ejection fraction (LV EF) (p><0.05). In the comparison group, only an increase in LV ESV was noted (p=0.04). The index of the indexed volume of the left atrium did not show significant dynamics in the main group (p=0.79), but showed a significant decrease>˂0.01), a decrease in the daily dose of the parenteral diuretic furosemide from 54 mg to 26 mg (p<0.01). A decrease in systolic blood pressure (SBP) occurred in both groups (p>˂0.01), but it was more pronounced in the comparison group [from 141 (110; 160) to 110 (90; 120) mm Hg) compared to the main group [from 140 (120; 160) to 120 (110; 130) mm Hg]. According to echocardiography data in the main group, there was a decrease in the indexed volume of the right atrium, the end-systolic volume of the left ventricle (LV ESV) and systolic pressure in the pulmonary artery, an increase in the LV ejection fraction (LV EF) (p˂0.05). In the comparison group, only an increase in LV ESV was noted (p=0.04). The index of the indexed volume of the left atrium did not show significant dynamics in the main group (p=0.79), but showed a significant decrease in the 2nd and 3rd control points compared to the control group (p=0.01 and p=0.02). Complications, against the background of taking empagliflozin, were not noted: there were no episodes of hypotension (SBP˂90 mm Hg), hypoglycemia, acute kidney injury.Conclusion. The results obtained indicate the safety of empagliflozin in patients with ADHF, regardless of the status of carbohydrate metabolism and LV EF, as well as taking into account the clinical (more intense positive dynamics of clinical symptoms of ADHF) and hemodynamic (smooth decrease in SBP, increased diuretic effect) effects of empagliflozin, this drug should be considered as an effective and safe supplement to the main therapy from the first day of hospitalization in patients with stable hemodynamic parameters.
