Vascular aging phenotypes based on VaSerа-screening results in young people with hypertension: Place of connective tissue dysplasia

Abstract

Objective. To assess the occurrence of various vascular aging phenotypes among young people, depending on the level of blood pressure (BP) and in relation to risk factors (RF) and the presence of connective tissue dysplasia (CTD).Design and methods. In total, 250 young people (88 boys and 162 girls) aged from 18 to 25 years old were examined at the University Health Center. All the subjects were divided into tercile groups based on cardio-ankle vascular index (CAVI), determined by the VaSera-1500 (Fucuda Denshia, Japan). According to the latest expert recommendations the third tercile group corresponds to early vascular aging or EVA syndrome. The first tercile group corresponds to favorable vascular aging. We have analyzed the representation of various vascular phenotypes in individuals with elevated and normal BP, as well as the main RF and external signs of CTD in each of CAVI-tercile group. Data processing was performed using the software package “Statistica 10.0” (StatSoft Inc., USA).Results. Among young people with office hypertension and high normal BP, the EVA phenotype and phenotypes of normal and favorable vascular aging are equally distributed. In persons with office normal and elevated BP, vascular stiffness correlates with weight, body mass index and waist circumference (with the increase in arterial rigidity these indicators decrease). CTD is registered among subjects with severe vascular remodeling both in boys and girls.Conclusions. Our data indicate the feasibility of angiology screening for identification of vascular aging phenotypes as a part of preventive measures among young people, regardless of the level of initial office BP. This strategy strategy will contribute to a more differentiated identification of risk groups and more individualized preventive interventions based on vascular aging phenotypes.
