Objective: To investigate the relationship between serum neurofilament protein heavy chain (NF-H) expression and cognitive function in patients with asymptomatic carotid artery stenosis before and after carotid artery stenting(CAS). Methods: From May 2018 to August 2019, 40 patients with asymptomatic carotid stenosis and mild cognitive impairment were admitted to the Department of Neurology of Sichuan Provincial People's Hospital as experimental group, and the control group was 40 health people. Blood samples in the operated patients were collected at three different points: 24 hours prior to CAS, 3 months after CAS in experimental group. Blood samples in control group were also collected. The serum concentrations of the NF-H were measured by ELISA. The cognitive function of the patients was evaluated by the mini-mental state examination(MMSE) and Montreal Cognitive Assessment(MoCA) before and 3 months after CAS.Compare the difference of serum NF-H expression level and the changes of cognitive function before and 3 months after operation. Results: Serum NF-H level of the patients in the experimental group was higher than that in the control group, with statistical difference (P< 0.01). The preoperative MMSE score in the experimental group was (26.08±1.59), which was lower than that in the control group (27.93±2.95), and the difference was statistically significant (P< 0.05). The preoperative MoCA score of the experimental group was significantly lower than that of the control group (24.48±1.89) vs (27.97±1.21), and the difference was statistically significant, (P< 0.01). Serum NF-H level decreased significantly (P< 0.01) in 3 months after operation compared with that before operation, and this is consistent with the improvement of cognitive function after 3 months--preoperative and postoperative comparison: MMSE(26.08±1.59) vs (27.48±1.95)(P< 0.05); MoCA(24.48±1.89) vs (26.83±.49)(P< 0.05). Pearson correlation analysis showed that the serum NF-H level was negatively correlated with MMSE score and MoCA score (P< 0.05). Conclusion: The patient with asymptomatic carotid artery stenosis have different degrees of brain injury and cognitive dysfunction. CAS can effectively improve the cognitive impairment associated with carotid stenosis, and the brain injury marker NF-H may be a biomarker for early recognition of cognitive impairment and may be used to monitor the cognitive function changes in patients after CAS.
