Relevance. Arterial hypertension is one of the most common cardiovascular diseases in the adult population, but much has already been achieved in its treatment. The advantages of combination therapy, according to the clinical recommendations "Arterial Hypertension in Adults" in 2020, are as follows: an increase in the degree of blood pressure reduction is much stronger than an increase in the dose of a single drug; the possibility of physiological and pharmacological synergy between drugs of different classes, which may underlie a more pronounced reduction in blood pressure and better tolerability of treatment; suppression of the opposite mechanisms of increasing blood pressure. Aim. Aim of the study was to study the effect of the antihypertensive drug - Konsilar-D24 on the clinical picture, HRV data, and hemodynamic parameters in patients with stage II hypertension of the 2nd degree. Materials and methods. 40 patients with stage II AH and grade 2 AH were examined. During the outpatient examination, all patients were evaluated for HRV, SCAD, SMAD, ECHO-KG, ECG, GFR, laboratory and biochemical examination (UAC, OAM, blood bch-creatinine, urea, glucose, ASAT, ALAT), and the SF-36 quality of life questionnaire. Results. An increase in SVVR, a decrease in blood pressure, and an increase in the quality of life of the patient. Discussion: Konsilar-D24 is an effective antihypertensive agent for grade 2 hypertension in the complex treatment of stage II hypertension. Against the background of therapy, there is a persistent achievement of target figures, an increase in vagal tone. There is a metabolic neutrality of the drug, as well as nephro and cardioprotective effects.
