Abstract
There is a delicate balance between thrombosis and hemostasis – primary hemostasis (platelet plug), secondary hemostasis (fibrin clot), and fibrinolysis. On the coagulation side, a balance between procoagulants and anticoagulants and pro-fibrinolytics and anti-fibrinolytics is crucial to maintain physiological hemostasis. Similarly, on the platelet side, a balance between endogenous platelet activators and inhibitors is also critical in the maintenance of hemostasis. When using either antiplatelet or anticoagulants to prevent or treat either arterial or venous thrombosis, a risk of bleeding exists due to the shift in the balance between thrombosis and hemostasis.
