[Blood viscosity in patients with ischemic heart disease].

AIM

To elucidate relation of blood viscosity to development of a hypoxic state of microcirculation in patients with ischemic heart disease (IHD).

MATERIAL AND METHODS

We examined 42 patients with postmyocardial infarction cardiosclerosis and 30 healthy persons (control group). Measurements were made by rotatory viscometer at shear rates 1 - 10 s(-1).

RESULTS

In patients with IHD we found increased blood viscosity and lowering of blood fluidity limit. Pathogenesis of increased blood viscosity in patients with IHD involves elevated blood fibrinogen, enhanced aggregation ability of erythrocytes, and accelerated formation of fine and large erythrocyte aggregates.
