Anticoagulation is the process of reducing the endogenous pathway and endogenous coagulation pathway by applying anticoagulant drugs to reduce the process of fibrin thrombosis. Antiplatelet is the process of reducing platelet thrombosis by taking anti-platelet drugs that reduce the adhesion and aggregation function of platelets. In clinical practice, commonly used anticoagulant drugs are warfarin and heparin, which reduce the possibility of fibrinogen thrombosis through different anticoagulation pathways. Warfarin, for example, is often used in the anticoagulation treatment after heart valve surgery, while heparin is often used in the treatment of lower extremity venous thrombosis. Anti-platelet drugs commonly include aspirin, Bolivar, etc. These drugs achieve the function of preventing platelet aggregation through different links, thus preventing the formation of platelet thrombosis. In clinical practice, they are used for the prevention of coronary heart disease and cerebral thrombosis.
