    Abstract:

    Coronary artery bypass grafting-related bleeding and associated transfusion is a concern with dual antiplatelet therapy in patients with acute coronary syndromes. The objective of the present study was to characterize a potential risk-adjusted difference in transfusion requirements between prasugrel and clopidogrel cohorts.The data from 422 patients undergoing isolated coronary artery bypass grafting from the TRial to assess Improvement in Therapeutic Outcomes by optimizing platelet InhibitioN with prasugrel Thrombolysis In Myocardial Infarction 38 were analyzed retrospectively.We found no difference in baseline transfusion risk scores between cohorts. As predicted, the number of units of red blood cells transfused perioperatively correlated with the transfusion risk score (P < .0001). Overall, the 12-hour chest tube drainage volumes and platelet transfusion rates in the prasugrel cohort were significantly greater. However, no statistically significant differences were found in the number of red blood cell transfusions, total hemostatic components transfused, or total blood donor exposure. A significantly greater number of platelet units were transfused postoperatively in the prasugrel patients who underwent surgery within 5 days or less after withdrawal of drug. In an analysis adjusted for the predicted risk of mortality, total donor exposure was not associated with increased mortality.The use of prasugrel compared with clopidogrel was associated with greater 12-hour chest tube drainage volumes and platelet transfusion rates but without any significant differences in red blood cell transfusions, total hemostatic components transfused, or total blood donor exposure.
