The study of vascular wall stiffness in patients with arterial hypertension depending on some factors of risk and associated clinical conditions

Abstract

Aim. To study the effect of gender, age, duration of disease and different forms of ischemic heart disease on the stiffness of the vascular wall in patients with arterial hypertension by determining the propagation velocity of the pulse wave. Materials and methods. In order to study the propagation velocity of the pulse wave it was examined 369 patients with the method of volumetric sphygmography. In all patients was diagnosed arterial hypertension I-III stage, 1-3 degree, besides 47 patients were diagnosed with stable angina I-III functional class, 50 patients had a history of prior myocardial infarction. The investigation was held with the help of hardware complex "Poli-Spektr" made by Neirosoft firm (city Ivanovo) by the classical method of determining the propagation velocity of the pulse wave using synchronous registration sphygmograms of the carotid, radial and femoral arteries. Results. Patients with arterial hypertension had statistically higher velocity of pulse wave propagation for elastic-type vessels in comparison with healthy volunteers (9.48±0.18 и 7.28±0.64 cm/sec; р
