Randomized Evaluation of D-dimer Guiding dUration of Oral antiCoagulation thErapy

Summary

Guidelines recommended that patients with bioprosthetic heart valves (BHV) only need 6 months oral anticoagulation therapy after operation. However, a small part of patients still suffered thrombotic events after withdrawal of warfarin, which means these patients may need extend anticoagulation therapy. D-dimer, a sensitive marker of thrombosis or prethromboembolism state. Previous studies have demostrated that patients with elevated D-dimer levels have significant more clinical outcomes than those with nagative D-dimer levels. The aim of this study was to evaluate whether D-dimer could guide the duration of oral anticoagulation therapy in patients with BHV.
