Summary
The optimal intensity of oral anticoagulation in China patients undergoing mechanical valve replacements is still controversial due to the different risk profiles of thrombophilia and bleeding in Chinese patients. Elevated D-dimer could reflect a pro-thrombogenic or prothrombotic state, and thus might be used to decide the intensity of oral anticoagulation.
This study was to evaluate whether elevated D-dimer levels could help to determine the intensity of oral anticoagulation in patients with mechanical heart valve prostheses.
