Portable Device use for Arterial Stiffness Determination as a Control Method at the Recovery Stage of Rehabilitation

Aim: To create a device for PWPV evaluation which would be cheap and could be easily used not only at the inpatient but also at the restorative outpatient and health-resort stages of rehabilitation. Materials and Methods: The clinical examination included 90 people who were randomized into the group of observation (n=75) with patients of AH various degrees. 15 practically healthy persons were involved into the control group. PWPV was measured using a specially designed device according to the generally accepted carotid-femoral technique. Results: Our results showed that the PWPV of healthy persons measured using original device failed to differ statistically from the literature reference values and indicated the correspondence of the measurements we obtained with the data received using traditional apparatus. Out data of original PWPV measurement obtained from examined and treated patients do not differ from the results obtained in wide range of patients aged from 40 to 70 years with the 1st -2nd stages of AH. Conclusions: We described an efficacy of PWPV determination using an original device. The use of the proposed device does not contradict with the generally accepted method of vascular stiffness measuring and studying. The results obtained on it are comparable with the data of the most used stationary device SphygmoCor for these purposes. The prospects of the device using are without the limitations in patients with vascular diseases at the stage of rehabilitation.
