Abstract:
Aspirin resistance defined by light transmittance aggregometry (LTA) or urinary 11-dehydro-thromboxane B2 has been associated with an increased risk of adverse clinical events. However, aspirin resistance based on the point-of-care VerifyNow-Aspirin assay (aspirin reaction unit > or = 550) shows poor sensitivity compared with LTA. In aspirin-treated patients, activation by cyclooxygenase- independent pathways may be associated with residual platelet reactivity, which may cause adverse clinical outcomes in some portion. A large-scale, prospective study using several platelet function assays should be performed to establish the long-term clinical significance of antiplatelet resistance in Korean patients treated with coronary stenting. Accordingly, we can apply tailored antiplatelet therapy in resistant patients.
