The distribution of whole blood viscosity, its determinants and relationship with arterial blood pressure in the community: cross-sectional analysis …

2015

Background: Blood viscosity has a role in modulating cardiovascular homeostasis; changes in this parameter have been associated with cardiovascular mortality and morbidity. However, it remains unclear whether these changes are (1) involved in the pathophysiology of disease, (2) an epiphenomenon, or (3) the expression of counterregulatory mechanisms. We report data on the normal values of blood viscosity and its association with cardiovascular risk factors, prevalent cardiovascular disease, and blood pressure in a large population-based cohort study. Methods and results: Viscosity was calculated using validated formulae and its associations were explored in 15,010 participants (mean 55.0, mi…
