Increased blood viscosity implies clustering of multiple metabolic abnormalities in essential hypertension

n skeletal muscle, increased blood viscosity can reduce nutritional blood supply and thereby influencing insulin
sensitivity, uric acid production and oxygen utility. Although blood viscosity elevates in hypertension, the
associations of blood viscosity with limbs circulation and metabolism reminded to be elucidated in hypertension. In
116 untreated essential hypertensives without apparent cardiovascular damages, blood viscosity, forearm vascular
resistanceandbiochemicalindicesweremeasuredbyfalling-ballmicroviscometer,venous-occlusionplethysmography
and laboratory tests, respectively. The relationships between blood viscosity and the other measured parameters were
evaluated. Forearm vascular resistance correlated positively with blood viscosity (r=0.240). Concomitantly with the
increase in blood viscosity, both plasma insulin and HOMA ratio elevated without changes in blood glucose (r=0.238,
0.205). Additionally, serum uric acid, plasma lactate and C-reactive protein also elevated together with the increase
in blood viscosity (r=0.404, 0.286, 0.199). In essential hypertensives, increase blood viscosity was associated with the
worsening of insulin sensitivity, uric metabolism, aerobic metabolism and inflammation as well as the reduction in
limbs blood flow. The increased blood viscosity could imply the clustering of multiple metabolic abnormalities in
essential hypertension.
