Furthermore, platelet activation has been well identified in carotid stenosis by numerous studies and plays an important role in the recurrence of stroke.32, 33, 37 In addition, recent studies highlighted the potential role of the neutrophil‐platelet complex in thrombogenicity in symptomatic carotid artery stenosis.32, 33 In this study, the neutrophil‐platelet complex was examined by detecting the CD41 + /CD66b cells in samples from each group. The gene discussed is CEACAM8; the disease is Stroke.
