Abstract
Clopidogrel resistance is associated with stent thrombosis. Prasugrel achieves greater platelet inhibition with less variability among patients than does clopidogrel. Thus, a patient who had stent thrombosis due to clopidogrel resistance may receive prasugrel to prevent repeated episodes of stent thrombosis. This case report describes a case of repetitive stent thrombosis in which resistance not only to clopidogrel, but also to prasugrel, was observed. <Learning objective: In the face of clopidogrel resistance, prescribing prasugrel may be an acceptable treatment option. However, cross-unresponsiveness may be observed between clopidogrel and prasugrel. Thus, platelet function assay should be performed in patients with stent thrombosis, even when clopidogrel is replaced with prasugrel.>.
