Antiplatelet therapy for patients with diabetes mellitus and acute coronary syndrome.

Abstract

In diabetes mellitus, platelet hyperreactivity is common and may contribute to the high incidence of cardiovascular disease; dual antiplatelet therapy reduces the risk of recurrence. Prasugrel or ticagrelor provides a greater, more consistent antiplatelet effect than clopidogrel. Prasugrel provides greater clinical benefit than clopidogrel in patients with diabetes (hazard ratio [HR], 0.70; P<0.001) versus those without diabetes (HR, 0.86; P=0.02), due to greater reductions in cardiovascular events and no increased major bleeding. Similar clinical benefits are seen with ticagrelor versus clopidogrel in patients with and without diabetes. Evidence suggests that prasugrel/aspirin may provide particular advantages for patients with diabetes mellitus.
