Summary

This study aims to evaluate the clinical significance of clopidogrel resistance-associated biomarkers (TMAO, C1q, and C4BPα) in patients receiving cerebral artery stents, and to develop an integrated predictive model incorporating these novel biomarkers along with CYP2C19 genotyping data for accurate clopidogrel resistance prediction in Chinese populations. By establishing this multidimensional assessment system, we intend to provide reliable risk stratification for post-stenting ischemic events and in-stent restenosis, ultimately facilitating personalized antiplatelet therapy decisions in cerebrovascular interventions. The proposed model may serve as a valuable clinical tool to optimize treatment strategies and improve outcomes for stented patients at risk of clopidogrel resistance.
