The aim: To improve the effectiveness of treatment of patients with hypertension using metabolic therapy based on the evaluation of endothelial dysfunction indicators, markers of inflammation, and blood lipid spectrum.

Materials and methods: A clinical study was performed with 72 patients (34 male and 38 female) with stage 2 arterial hypertension of 2-3 degrees, admitted to the cardiology department of the municipal non-profit enterprise “Lviv Emergency Clinical Hospital”. The mean age of patients was 44.8±8.5 years. Patients were divided into 2 groups: Group I was taking quercetin in addition to basic therapy (Ramipril/Amlodipine in individually adjusted dose); Group II – had basic therapy following the clinical protocol. The level of nitric oxide, IL-1, IL-6, TNF-a, CRP, seromucoid, blood lipid spectrum was determined.

Results: There is a significant decrease in the NO and CRP levels. There is a decrease in the TNF-a level by 31.27±2.13 (p<0.01) after the treatment of patients with hypertension. The TNF-a level decreased by 22.2±1.13 (p<0.01) with the use of basic therapy. IL-1 decreased significantly in the two groups, but it was more pronounced in group I, by 40.68±1.67 (p<0.01) and 21.4±2.1 in group II (p<0.05). There is a positive change in the blood lipid spectrum, but the changes were more pronounced in the group of patients receiving metabolic therapy.

Conclusions: The use of quercetin (Corvitin, Quertin) in combination therapy with the combined antihypertensive drug containing ramipril/amlodipine (Egis-Hungary) significantly reduces the levels of nitric oxide, CRP, IL-1, and blood lipid spectrum, which reduces the incidence of complications and progression of hypertension.
