Inhibition of the ouabain-sensitive Na-K-ATPase by digoxin significantly decreases erythrocyte deformability (5). Since first a decrease in this transport system has been discussed as a pathogenetic factor in the development of essential hypertension and second an increase in blood viscosity, due...

Haemoconcentration, Shear-Stress Increase and Carotid Artery Diameter Regulation After Furosemide Administration in Older Hypertensives.
The aim of the present study was to determine whether changes of carotid wall shear stress induced by changes in blood viscosity after diureticadministration cause carotid arterial dilatation in elderly hypertensives, as reported in the cat. Arterial wall shear rate (ultrasound technique,...

Blood Viscosity: Effects of Mental Stress and Relations to Autonomic Nervous System Function and Insulin Sensitivity.
We studied effects of mental stress on whole-blood viscosity (WBV) and blood pressure (BP), and relations between WBV and autonomic nervoussystem activity and insulin sensitivity. We measured WBV (rotational rheometer), plasma noradrenaline (NA), finger BP, heart rate variability (HRV) and...
Effects of Perindopril and Carvedilol on Endothelium-Dependent Vascular Functions in Patients With Diabetes and Hypertension.
OBJECTIVE: To compare the effects of the ACE inhibitor perindopril and the beta-blocker carvedilol on blood pressure and endothelial functions inNIDDM patients with hypertension. RESEARCH DESIGN AND METHODS: We conducted a double-blind randomized trial in 26 patients with NIDDM and mild...
Hemorheological Changes and Characteristic Parameters Derived From Whole Blood Viscometry in Chronic Heroin Addicts.
A group of 15 chronic opioid addicts (DA) with mean age 26.5+/-7.3 years was studied by means of a rotational Contraves Low Shear 30 viscometer and the results have been compared with a control group of 19 healthy subjects. It was found that the mean whole blood viscosity values of the...
