Natural history of antiplatelet nonresponders undergoing carotid artery stenting.
Routine antiplatelet responsiveness testing for patients undergoing carotid artery stenting procedures is not performed at most endovascular centers and remains a topic of controversy within the neurointerventional community. The objective of this study was to determine if nonresponsiveness to acetylsalicylic acid or clopidogrel was associated with the development of symptomatic thromboembolic events in patients undergoing carotid stenting procedures. ⋯ This study demonstrated that patients who were identified as clopidogrel nonresponders, using whole blood impedance aggregometry, were at an increased risk of developing thromboembolic events. Larger studies are needed to assess the utility of routine platelet function testing prior to carotid artery stenting procedures.
