Novel Anticoagulants and Dual Antiplatelet Therapy Conclusions-1 1. In RE-LY triple therapy (OAC, ASA and clopidogrel) increases major bleeding by 60% irrespective the anticoagulant used 2. The ischemic AND bleeding benefit of dabigatran over warfarin is maintained with antiplatelet therapy 3. The lowest rate of ICH in this study is seen with low dose dabigatran, which is even lower than with warfarin without antiplatelets
Novel Anticoagulants and Dual Antiplatelet Therapy Conclusions-2 Low dose dabigatran seems a good candidate for patients with AF in the need of antiplatelet therapy (e.g, stenting and/or ACS), but this has to be confirmed in a new randomized trial against warfarin. However, it is unlikely, that such a trial will be done 4.
