The Influence of Beetroot Powder at a Dose of 20 g on Blood Pressure, Microcirculation, and Biochemical Markers in Men With Arterial Hypertension.SVEKLA2025.

Brief summary (registry, in English)

Objective: to evaluate the effectiveness of using a food product, dry finely dispersed beetroot powder in a dose of 20 g, containing 800 mg of nitrate (NO3-), in relation to the regulation of blood pressure in men with hypertension who reached the target blood pressure level while taking optimal antihypertensive therapy. Characteristics of the study: randomized, open, and cross-sectional. Relevance of the study Currently, it is recognized that vasodilatory endothelial dysfunction due to impaired synthesis and bioavailability of endogenous nitric oxide (NO) is a characteristic change in patients with arterial hypertension (AH) and plays one of the key roles in the development and progression of this pathology. Nitrate (NO3-), contained in food products, the highest content of which is found in beetroot, is converted into NO in the body after consumption, which can have a positive effect on the state of the cardiovascular system and lead to a decrease in blood pressure. Indeed, this assumption has been confirmed in various clinical studies. The results of the conducted studies demonstrate the positive effect of beetroot juice enriched with NO3- on the functional parameters of the cardiovascular system, in particular, the level of SAD and DBP, vasodilator function, endothelium and arterial stiffness, both in patients with hypertension and conditionally healthy people. However, most of the studies conducted in this field either include a relatively small number of subjects with hypertension, or do not have a cross-sectional design, which is a limitation in formulating unambiguous conclusions about the positive effect of taking beetroot enriched with NO3- on lowering blood pressure in this category of patients. Moreover, the effect of beetroot juice on the functional state of the peripheral arterial bed (terminal muscular arteries, distributive and precapillary arterioles) remains unexplored, which, due to the increased bioavailability of NO by the vascular wall, may be expressed in a decrease in arterial stiffness, a decrease in smooth muscle cell tone (MMC) and a decrease in total peripheral vascular resistance, which will have a positive effect on tissue homeostasis. It is relevant to study the effect of course intake of beetroot enriched with NO3- on the functional state of all arterial links and regulation of blood pressure in patients with hypertension. Research materials and methods The study will be performed on the basis of the Laboratory of Microcirculation and Regional Blood Circulation of the Department of Fundamental and Applied Aspects of Obesity and the Center for Coordination of Fundamental Scientific Activities of the Federal State Budgetary Institution "NMIC TPM" of the Ministry of Health of the Russian Federation. The study is planned to include 60 men aged 18-60 years with hypertension who reached the target blood pressure level according to office measurement and daily blood pressure monitoring (SMAD) on the background of regular intake of AGT. Research design The study will consist of two screening stages and one main stage (Figure 1). Patients will be divided into 2 equal groups of 30 men using simple randomization using the closed envelope method. The first group will be assigned a one-week course of daily intake of dry fine beetroot powder in a dose of 20 g containing 800 mg of NO3- (food product), the second group will continue regular intake of AGT. After 7 days, the crossing will be performed: patients of the first group will continue to receive regular AGT, and patients of the second group will receive a food product. At each stage, all participants undergo blood pressure and heart rate (HR) measurements, anthropometry, basic research methods\* and SMAD. The total duration of the study will be 14-16 days.
