Stent Thrombosis Patients with Hyporesponsiveness to Clopidogrel, Prasugrel, and Ticagrelor: A Case Series Using Short Thromboelastography

Figure 2

Short thromboelastography traces showing adequate response to aspirin 75 mg daily and hyporesponse to P₂Y₁₂ inhibitors in second patient. (a) Patient 2 clotting response to AA when on 75 mg daily aspirin, producing a %CI(AA) of 61, an adequate response to aspirin. (b) Patient 2 clotting response to ADP when on 75 mg clopidogrel daily, producing a %CI(ADP) of 21 (nonresponse to clopidogrel). (c) Patient 2 clotting response to ADP when on 10 mg prasugrel daily, producing a %CI(ADP) of 17 (nonresponse to prasugrel). (d) Patient 2 clotting response to ADP when on 90 mg ticagrelor twice daily, producing a %CI(ADP) of −21 (nonresponse to ticagrelor).
