ASSESSMENT OF THE RELATIONSHIP OF VISCERAL AND PARIETAL FAT IN THE BODY COMPOSITION AND DISORDERS OF NECK ARTERIAL VESSELS

Abstract

Currently, obesity is considered as a risk factor for many comorbid conditions. Computed tomography (CT) is considered the «gold standard» for analyzing the composition of the human body, in particular adipose tissue, but this method carries radiation exposure. The most accessible alternative non-invasive method is bioimbisometry (BIM), but the accuracy of its indicators in clinical practice today is questioned. Target. To carry out a comparative analysis of the indicators of visceral and parietal fat obtained by methods of non-invasive and minimally invasive diagnostics to identify the most informative, safe, cost-effective screening markers. Materials and methods. After basic anthropometric studies and angiography (AH) of the arteries of the head and neck in patients with clinical manifestations of vascular disorders of varying severity, an analysis of the body composition (BSC) of those examined using the Tanita analyzer scales was carried out. Results. It was found that the body mass index (BMI) changed depending on the absence or presence of arterial stenosis on CT data. According to CT, depending on the degree of progression of stenosis by plaques, a positive correlation was found between the growth of epicardial adipose tissue (EFT) and perivascular adipose tissue (PAT); between BMI, obtained by anthropometry and RVT, obtained by CT; between the percentage of visceral fat obtained by the BIM method and EFT obtained by the CT method. The study obtained a negative correlation between the degree of hydration of the body and EFT. The BMI obtained by the anthropometry method and the BIM method when compared by the Mann-Whitney test did not differ statistically significantly, which indicates the possibility of express BMI assessment by the BIM method, taking into account the measurement error. Conclusions. The volume of EFT and RVT, measured on CT, can act as an independent marker in assessing the severity of atherosclerotic lesions. In the course of the study, it was proved that the CST indices obtained by the BIM method did not contradict the CT data, and increased depending on the progression of arterial stenosis.
