Thrombin activates various components of coagulation pathway, such as platelets, factors V, VIII and IX, protein C and thrombin-activa table fibrinolysis inhibitor to amplify the coagulation cascade. Most importantly, thrombin converts fibrinogen to fibrin, ultimately forming

Coagulation factors can be proteolytic enzymes (zymogens) or non-enzymatic. called the waterfall or cascade model of coagulation and led to the term “the coagulation cascade”. Heparin cofactor II: This is a specific thrombin antag

Common. Pathway. The Coagulation Cascade.

Anticoagulation with heparin for CPB depends on AT to inhibit clotting as heparin, alone, has no effect on coagulation. Heparin catalyzes AT inhibition of thrombin over 1000-fold by binding to a lysine residue on AT and altering its conformation.

Newer classes, known as Low Molecular Weight Heparin (LMWH), are derived by purification of the smaller molecules within UFH. vitamin K antagonists (VKA) and unfractionated heparin (UFH) relate mainly to the varying responsiveness of test reagent to single and/or multiple factor deficiencies and inhibitors. There is considerable variability in the PT thromboplastin reagent to the coagulation defect caused by VKA. Therefore, to allow PT results from different Use with caution with medication that affects the coagulation cascade due to additive effects that increase the risk of bleeding. When a patient is receiving IV heparin therapy to treat a blood clot, it may be overlapped with oral warfarin to establish anticoagulation therapy after discharge.

Binds irreversibly/inhibits prothrombotic actions of factor Xa and thrombin; The anticoagulant effects of heparin rely on its interaction with antithrombin. Heparin depends on antithrombin as a cofactor 7 coagulation cascade occurred due to introduction of a cell based model which emphasizes the importance of tissue factor as the initiator of the coagulation cascade and the pivotal role of platelets for intact haemostasis.
