I018 Short and long lasting action of shear stress changes on diameter of conduit arteries in patients with arterial hypertension

Objectives Aim of the study was to investigate short and long lasting actions of shear stress changes on vascular diameter of brachial artery in patients with arterial hypertension. Methods 57 patients with arterial hypertension (mean age±SD, 51.26±1.94; 30 men and 27 women) and 17 healthy controls...

Description
Summary:Objectives Aim of the study was to investigate short and long lasting actions of shear stress changes on vascular diameter of brachial artery in patients with arterial hypertension. Methods 57 patients with arterial hypertension (mean age±SD, 51.26±1.94; 30 men and 27 women) and 17 healthy controls (mean age±SD, 51±5.41 ; 9 men and 8 women) were included in the study. All the subjects underwent to the investigation of vascular characteristics via high resolution vascular dopplerechography and clinical blood pressure investigations. Patients with cardiovascular, peripheral and cerebrovascular diseases, diabetes mellitus, smokers, pregnant, obese as well as those with secondary forms of hypertension, ischemic heart disease and heart failure were excluded from the study. Results Compared with normotensive control subjects, initial vascular diameter (D0), was higher in hypertensive subjects (3.76±0.28 vs. 4.32±0.14, P
