ABSTRACT

The aim of this study was to evaluate the orthostatic changes in different vascular beds BP indicators and PWV in 40healthy young volunteers in passive tilting 60º. In horizontal position, at rest, the foot artery BP is significantly higher thanbrachial one. Tilt up at 60º does not cause significant changes in the brachial BP, while in the distal artery there is a significantincreasing in SBP and DBP and a decreasing in PBP with a simultaneous increasing in PWV. The influence of the gender factoron orthostatic changes in blood pressure and PWV was revealed.The height has a significant effect on the increasing in blood pressure in distal parts of the vasculature during tilt up, butpractically does not influence on the PWV in the horizontal and tilt up positions of the subjects.


KEYWORDS: systolic blood pressure, diastolic arterial pressure, pulse blood pressure, pulse wave velocity, passive orthostatic test, healthy volunteers, risk factors for cardiovascular diseases
