Blood viscosity red cell flexibility hematocrit and plasma fibrinogen in patients with angina/



Blood viscosity red cell flexibility hematocrit and plasma fibrinogen in patients with angina/



Lancet 2(8045): 943-945



Whole-blood viscosity, hematocrit (packed-cell volume), red-cell flexibility and plasma-fibrinogen concentration were measured in 22 patients with angina and 22 controls. All 4 variables were significantly higher in patients with angina. When the viscosity was corrected to a standard hematocrit (45%), there was no significant difference in the mean viscosity of the 2 groups, indicating that the higher viscosity in patients with angina is the result of the higher hematocrit. Increased red-cell flexibility tends to counteract the effect of increased plasma-fibrinogen concentration, which tends to increase blood-viscosity.
