Abstract. It could be conjectured that the hemorheological disorders are involved in development of the ischemic heart disease. But this fact was so far insufficiently cleared up. The present studies were carried out in patients with various forms of chronic ischemic heart disease. We investigated the most significant factor of rheological disorders in the microcirculation, the erythrocyte aggregability, which a technique that provided us with the direct and quantitative data. Simultaneously we investigated in the some patients the tone of the resistance arteries of the hand with an original non-invasive technique. We found that the erythrocyte aggregability increased almost twice in the blood of investigated patients as compared to the healthy control group. The aggregability was positively correlated with severity of the disease.

The most pronounced hemorheological disorders were found in the patients with the heart failure. As to the arteriolar resistance index, it was increased only in 45 per cent of all the investigated patients and no significant difference between the patients with the heart failure and without it was found available. We concludes that the blood rheological disorders represent themselves a factor that plays a significant role in pathogenesis of development of the heart disease.[/su_animate]

Significance of the hemorheological disorders in development of acute vascular syndromes is presenltky well known, but their role in pathogenesis of chronic ischemic heart disease is not yet sufficiently analyzed. Aim of the present study was investigation of the relationship between the hemorheological, vascular and hemodynamic factors during the ischemic heart disease.

ABSTRACT The aim of the present study is comparison of changes of principal hemorheological factors responsible for blood flow disorders in the microcirculation in patients with ischemic brain infarcts. It was found that in venous blood samples the erythrocyte aggregability (examined with a direct, highly sensitive, quantitative technique) was considerably more increased (by mean of 120%) than the blood plasma fibrinogen contents, blood plasma viscosity, and hematocrit which increased only by 23.7%, 7.4% and 3.6%, respectively, as compared to the same hemorheological factors in the healthy controls.

Abstract
[su_animate type=”tada”]
The aim of the present study was the comparative analysis of the role of specific hemorheological derangements in the pathogenesis of ischemic brain infarcts with and without diabetes mellitus. Blood plasma viscosity, as well as red blood cells (RBC) aggregability were quantitatively investigated in all patients during the study. Both of the above mentioned indices of hemorheological disorders were significantly higher in the patients with brain infarcts and diabetes mellitus as compared to the control and the group of ischemic brain infarcts without diabetes.[/su_animate]
