Abstract:

Objective To explore the application value of serum cystatin C (CysC) and cluster of differentiation 147 (CD147) in predicting restenosis after intracranial artery stenosis stenting (ICASS) in patients with acute ischemic stroke (AIS). Methods A total of 151 AIS patients who received ICASS were selected as the study group, and 112 healthy individuals who underwent physical examinations during the same period were chosen as the control group. The study group was further divided into the restenosis group (30 cases) and the non-stenosis group (121 cases) based on the restenosis status within 6 months after ICASS. The serum CysC levels of the subjects were detected by immunoturbidimetry, and the serum CD147 levels were measured by enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was conducted to identify factors influencing restenosis after ICASS in AIS patients. The receiver operating characteristic (ROC) curve was used to evaluate the application efficacy of serum CysC and CD147 levels in predicting restenosis after ICASS in AIS patients. Results Serum levels of CysC and CD147 were higher in the study group than those in the control group (P<0.01). The proportion of patients with stenosis degree > 75% and serum levels of CysC and CD147 were higher in the restenosis group than those in the non-stenosis group (P<0.01). The degree of stenosis > 75% and the increased serum levels of CysC and CD147 were risk factors for restenosis after ICASS in AIS patients (P<0.01). ROC curve analysis showed that serum CysC and CD147 levels independently predicted the AUC of AIS patients with restenosis after ICASS were 0.845 and 0.850, respectively, and the combined predicted AUC was 0.942. The combined prediction efficiency was significantly better than that of single indicator prediction (P<0.05). Conclusion The increased levels of serum CysC and CD147 in AIS patients are risk factors for restenosis after ICASS, and the combination of the two is more effective in predicting intracranial artery restenosis after ICASS in AIS patients.
