Aim . To compare the novel arterial stiffness index START and cardio-ankle vascular (CAVI) in hypertensive (HTN) patients. Material methods. A total of 709 people with HTN aged 24 to 64 years were examined by volume sphygmography using VaSera VS-1000 (Fukuda Denshi, Japan). CAVI values obtained retrospectively from pulse wave velocity blood pressure studied an online calculator. Results The median score was within normal range (<9,0): 7,5 (6,6; 8,4) on right 7,4 (6,5; left. 6,25 (5,0;...
Aim . To compare the cardio-ankle vascular index (CAVI) and novel START stiffness assess their values correlations with clinical parameters. Material methods This multicenter study included 928 (403 men 525 women) randomly selected patients, aged 18 to 89 years (mean age, 41±15,8 years). Inclusion criteria were age over years. There following exclusion criteria: mental disorder, severe somatic diseases cancer, contraindications for volume sphygmography using Fukuda Denshi VS-1500 VaSera...
A numerical investigation of the evolution localized disturbances in form solitary waves is performed for full system equations describing planar a cold collisionless quasineutral plasma. It shown that, wide range angles inclination magnetic field vector to direction wave propagation, such kind initial disturbance never results propagating steadily, but leads decay due radiation periodic waves. These confirm recent theoretical conclusion Il'ichev [ J. Plasma Phys. 55 , 181–194 (1996)] about...
Objective. To study the possibility of using new arterial stiffness index START in healthy individuals different ages. Design and methods. The included data from without any medical history (n = 190), 121 men 69 women aged 25–64 years. Arterial was assessed for all subjects on VaSera VS-1000 device (Fukuda Denshi, Japan). As an additional parameter, domestic analyzed retrospectively. Results. average age participants 37,0 ± 8,1 years, 63,7 % men. median CAVI 6,6 right, 6,7 left. 5,02 5,3 A...
The solitonic, periodic and quasiperiodic solutions that obey the full system of transport equations describing one-dimensional motion a isotropic collisionless quasineutral plasma in magnetic field are treated. domains physical parameters such determined for fast slow magnetoacoustic branches, where solitary waves generalized exist. In parameter domain replaced by non-local waves, localized disturbances subject to decay, which has qualitatively different mechanisms waves. specific feature...
