Abstract

Aim: to study an association between metabolic syndrome and endothelial dysfunction as a regulator of hemorrheological and hemostatic processes in patients with chronic forms of cerebral circulatory insufficiency.
Subjects and methods. Forty-six patients with chronic cerebrovascular diseases (CCVD) were examined; of them 23 patients were diagnosed as having metabolic syndrome (MS). Clinical manifestations and major hemorrheological and hemostatic parameters, such as platelet and erythrocyte aggregation, fibrinogen, hematocrit, von Willebrand factor, antithrombin III, intercellular adhesion molecules (IAM), etc., were estimated. Endothelial dysfunction was studied from the data of cuff test (CT).
Results. MS promotes a higher degree of clinical symptomatology in patients with CCVD and more significant impairments in the hemorrheological and hemostatic systems. CT has shown that all the patients have an inadequate endothelial reaction - the antiaggregatory, fibrinolytic, and anticoagulant activities of the endothelium are lowered. There was endothelium-dependent hyperproduction of IAM.
Conclusion. The found changes suggest that MS has a considerable impact on the formation of a significant procoagulant state of the hemorrheological and hemostatic systems in patients with CCVD.
