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

Figure 1

Short thromboelastography traces showing adequate response to aspirin 150 mg daily and hyporesponse to P₂Y₁₂ inhibitors in first patient. (a) Patient 1 clotting response to AA when on 150 mg daily aspirin, producing a %CI(AA) of 71, an adequate response to aspirin. (b) Patient 1 clotting response to ADP when on 75 mg clopidogrel daily, producing a %CI(ADP) of 17 (nonresponse to clopidogrel). (c) Patient 1 clotting response to ADP when on 10 mg prasugrel daily, producing a %CI(ADP) of 9 (nonresponse to prasugrel). (d) Patient 1 clotting response to ADP when on 90 mg ticagrelor twice daily, producing a %CI(ADP) of 1 (nonresponse to ticagrelor).
