ABSTRACT

The relationship was studied between the ankle-arm index (K/R) and whole blood and plasma viscosity in patients suffering from diabetes mellitus type II with ischemia of lower extremities. The measurements were carried out in 96 patients (80 males and 16 females), of whom 72 were in stage II of Fontaine progression. Immediately after determination of the K/R index blood was taken from vena mediana cubiti adding Na2EDTA for rheological test. Whole blood viscosity was measured with a Low-Shear 100 Contraves viscometer immediately after sampling, and plasma viscosity was measured with a capillary viscometer of Ubbvelohd within 2 hours after sampling. By the method of regression analysis and linear correlation it was found that increased whole blood and plasma viscosity significantly correlated with reduced K/R value in the patients. The obtained results are analysed in biophysical and clinical aspects.
