Application of D-Dimer in oral anticoagulant therapy:

1.D-Dimer decides on the course of oral anticoagulation therapy

The optimal time limit for anticoagulation therapy for VTE patients or other thrombotic patients is still uncertain. Whether it is NOAC or VKA, international guidelines suggest that at the third month of anticoagulation treatment, the decision to extend anticoagulation should be based on the risk of bleeding, and D-Dimer can provide personalized information for this.

2.D-Dimer guides the adjustment of oral anticoagulant intensity

Warfarin and new oral anticoagulants are currently the most commonly used oral anticoagulants in clinical practice, both of which can reduce D The level of Dimer refers to the fact that the anticoagulant effect of a drug reduces the activation of the coagulation and fibrinolysis systems, indirectly leading to a decrease in D-Dimer levels. Experimental results have shown that D-Dimer guided anticoagulation effectively reduces the incidence of adverse events in patients.
