Hypertension (HT) occupies today a leading
position on the incidence and prevalence of all
cardiovascular disease (CVD). It is one of the main
risk factors determining the prognosis of morbidity
and mortality rate of the population of Ukraine due
to CVD. The incidence of HT in the world has the
character of a pandemic.
The purpose of the study. Was to determine
the indicators relationships of the blood vessels
viscoelasticity of the shoulder, and systemic
hemodynamics in patients with essential
hypertension.
Materials and methods. The purpose of the
study was carried out a comprehensive survey
of 224 HT patients, including 126 ones with
stage II hypertension of 1–3 degree arterial
hypertension and 98 people with 1–3 stage HT
of I degree of hypertension. Practically healthy
individuals were examined on an outpatient
basis. The study of viscoelasticity of arterial
vessels was conducted using the rheographic
complex «REOKOM» (HAI-Media, Kharkiv)
according to the standard Protocol. They
recorded rheogram of a shoulder and examined
the following indicators: quick time (tQKH) and
slow the blood flow (tSKH), the amplitude of
the systolic wave (ASV), the ratio of peripheral
resistance (RPR), the tone of large arteries
(TLA), the tone of the medium and small arteries
(TMSA), inter-amplitude indicator of diastolic
waves (MIDW).
Results. There were evaluated viscoelasticity
of shoulder vessels in patients with hypertension of the stage II and determined the relationship
with the indicators of systemic hemodynamics.
It was found that the increase in blood pressure
affects the increase in the parameters of systemic
hemodynamics and arterial stiffness.
Conclusions. 1. In patients with stage II HT, there
is a violation of the viscoelasticity of the muscular
type of arterial vessels with manifestations of their
walls remodeling, with an increase in time, both
fast and slow their blood filling.
2. There may be no significant differences
in systemic hemodynamic parameters between
subgroups of patients with stage II and stage I
HT, which indicates compensatory changes in the
cardiovascular system.
3. A strong direct relationship between average
dynamic pressure and the time of rapid blood filling,
as well as average dynamic pressure and the tonus
of large arteries were determined.
