Age Features of Structural and Hemodynamic Parameters of Great Vessels of the Neck in Non-Alcoholic Fatty Liver Disease and Overweight

Abstract

The investigations involved 290 patients (85 males and 205 females). The data of patients with non-alcoholic fatty liver disease (NAFLD) (steatosis), combined with overweight, and the data of control group patients with normal body weight without liver disease have been compared. Examined patients were divided into four age groups (according to World Health Organization criterion): 1st age group — from 25 to 34 years, 2nd — from 35 to 44 years, 3rd — from 45 to 59 years, 4th — from 60 to 75 years. Structural and hemodynamic parameters of great vessels of the neck, obtained in duplex investigation (ultrasound sonography in B-regime, color flow mapping and Doppler investigation), were analyzed. The changes of structural and hemodynamic parameters of great vessels of the neck (intima-media complex thickening, reduction in the linear velocity of blood flow) were determined. NAFLD (steatosis), associated with increased body weight, has a direct impact on the structural and hemodynamic state of great vessels of the neck. A correlation between NAFLD (steatosis), combined with increased body weight, and indicator of blood velocity — peak systolic flow velocity (p < 0.05) has been revealed. Violation of the structure and hemodynamics of the main vessels of the neck, detected during the complex duplex examination, is the result of direct impact of NAFLD (steatosis) and increased body weight and leads to the development of cardiovascular risk, mainly in groups of middle-aged and elderly patients.
