Antithrombotic Therapy Recommendations

1. Warfarin should not be routinely prescribed after CABG for graft patency unless patients have other indications for long-term antithrombotic therapy (such as AF, venous thromboembolism, or a mechanical prosthetic valve) (Class III; Level of Evidence A).
2. Antithrombotic alternatives to warfarin (dabigatran, apixaban, rivaroxaban) should not be routinely administered early after CABG until additional safety data have accrued (Class III; Level of Evidence C).
