BackgroundDabigatran reduces ischemic stroke in comparison with warfarin; however, given the lack of antidote, there is concern that it might increase bleeding when surgery or invasive procedures are required.Methods and ResultsThe current analysis was undertaken to compare the periprocedural bleeding risk of patients in the Randomized Evaluation of Long-Term Anticoagulation Therapy (RE-LY) trial treated with dabigatran and warfarin. Bleeding rates were evaluated from 7 days before until 30 days after invasive procedures, considering only the first procedure for each patient. A total of 4591 patients underwent at least 1 invasive procedure 24.7% of patients received dabigatran 110 mg, 25.4% received dabigatran 150 mg, and 25.9% received warfarin, P 0.34. Procedures included pacemaker/defibrillator insertion (10.3%), dental procedures (10.0%), diagnostic procedures (10.0%), cataract removal (9.3%), colonoscopy (8.6%), and joint replacement (6.2%). Among patients assigned to either dabigatran dose, the last dose of study drug was given 49 (35 85) hours before the procedure on comparison with 114 (87144) hours in patients receiving warfarin, P 0.001. There was no significant difference in the rates of periprocedural major bleeding between patients receiving dabigatran 110 mg (3.8%) or dabigatran 150 mg (5.1%) or warfarin (4.6%); dabigatran 110 mg versus warfarin relative risk, 0.83; 95% CI, 0.59 to 1.17; P 0.28; dabigatran 150 mg versus warfarin relative risk, 1.09; 95% CI, 0.80 to 1.49; P 0.58. Among patients having urgent surgery, major bleeding occurred in 17.8% with dabigatran 110 mg, 17.7% with dabigatran 150 mg, and 21.6% with warfarin dabigatran 110 mg; relative risk, 0.82; 95% CI, 0.48 to1.41; P 0.47; dabigatran 150 mg relative risk, 0.82; 95% CI, 0.50 to 1.35; P 0.44.Conclusions ...
