Changes in the blood coagulation system in patients with chronic heart failure

The article provides a review of scientifi c publications dedicated to the study of the hemostatic system in patients with chronic heart failure (CHF). Russian and foreign authors evaluated the risks of bleeding and thrombosis in patients with CHF, as well as changes in the content of individual markers and factors of the coagulation system. The review suggests that the results obtained are quite contradictory. On the one hand, data is presented on an increased risk of thrombosis, changes in the content of some endothelial markers that promote endothelial thrombogenicity, an increase in the content of platelet aggregation markers, and elevated levels of fi brinogen and thrombin. On the other hand, there is data on an increased risk of bleeding in patients with CHF, an increase in some endothelial markers that enhance the anticoagulant properties of the endothelium. From the analysis conducted, it can be concluded that this topic is not suffi  ciently studied, and it is diffi  cult to judge the hemostatic potential in patients with CHF at present. The use of integrated methods such as thromboelastography (TEG) and low-frequency piezothromboelastography (LF-PTEG) are a promising direction for studying this problem. The results obtained using these methods will likely allow for a more precise understanding of the features of the coagulation system functioning in patients with CHF.
