− | Thrombin levels are increased. Thrombin converts plasminogen into the active form, plasmin and initiates the fibrinolytic cascade. Fibrinolysis produces high levels of FDPs (fibrin degradation products) which are themselves anticoagulants, further fuelling the coagulation cascade. | + | Thrombin levels are increased.
