No Benefit From Platelet Transfusion for Gastrointestinal Bleeding in Patients Taking Antiplatelet Agents.

Background & Aims: Antiplatelet agents decrease cardiovascular events but increase gastrointestinal bleeding (GIB). Guidelines propose platelet transfusion for patients who take antiplatelet agents and have serious GIB. We investigated whether such patients are at decreased risk for rebleeding or increased risk for cardiovascular events after platelet transfusion.
