Seasonality of thrombogenic disorders in coronary atherosclerosis recrudescence

Abstract

Seasonality of thrombogenic disorders in coronary atherosclerosis recrudescence has been studied using a comparison of blood clotting peculiarities in patients with stable (n=167) and unstable angina (n=210) in different season periods. It was established that there is no common mechanism for decompensation of hemostasis system in progressive angina. The structure of thrombogenic disorders is nonhomogeneous. In winter the most important thing is an activating of prothrombinase producing, and in spring -reducing of heparin content and fibrinolysis activity inhibition. In summer thrombogenic changes are characterized by activating of intrinsic prothrombinase producing mechanism, antithrombin-III decreased activity and heparin content, fibrinolysis activity inhibition. In autumn an advanced euglobulin fibrinolysis block is enough to break the adaptation of hemostasis system.
