ABSTRACT
Whole blood viscosity contributes to the total peripheral resistance and has been suggested to be a risk factor for cardiovascular disease. Whole blood viscosity was measured using a direct technique in 105 healthy blood donors and in addition to establishing our reference values, the relationship to blood pressure and other cardiovascular risk factors was assessed. Whole blood viscosity correlated with systolic blood pressure (r = 0.29, p = 0.003), cholesterol (r = 0.21, p = 0.034), cholesterol/HDL cholesterol ratio (r = 0.33, p = 0.01), triglycerides (r = 0.37, p < 0.0005), body mass index (r = 0.29, p = 0.003) and waist-hip ratio (r = 0.30, p = 0.002). Subjects with systolic blood pressure > 130 mmHg (n = 16) had higher whole blood viscosity (p = 0.017) than those with lower blood pressure. Whole blood viscosity was significantly lower in women (n = 52) than in men at all shear rates (0.045 > p > 0.001). These results suggest that even in a population of healthy normotensive blood donors of a wide age range and either gender, there are positive correlations between directly assessed whole blood viscosity and a number of the components of the metabolic cardiovascular syndrome including systolic blood pressure, weight and blood lipids.
