Abstract:

Objective

To explore the correlation between serum expression levels of CircRNA_0003694 and post-stroke cognitive impairment (PSCI) in elderly patients with acute ischemic stroke (AIS).

Methods

The patients with AIS admitted to the Sanya Central Hospitaly Hainan Third People's Hospital January 2021 to December 2022 were prospectively included. The Montreal cognitive assessment (MoCA) was utilized to evaluate the occurrence of PSCI in patients with AIS at three months after onset. Based on the MoCA results, patients were categorized into PSCI and non-PSCI groups. Univariate analysis was conducted on both the PSCI and non-PSCI groups using t test, Mann Whitney U test, and χ2 test. Multivariate logistic regression was used to analyze the independent risk factors of PSCI in AIS patients.

Results

A total of 116 patients with AIS were included, with an average age of 67.25 years (±9.13 years), of which 75 were males (64.7%). There were 68 cases in the PSCI group (58.6%) and 48 cases in the non PSCI group (41.4%). The PSCI group had significantly higher age (70.36±9.18 vs 65.20±8.70, t=4.520, P=0.013), modified Rankin scale (mRS) score (27.9% vs 10.4%, χ2=5.586, P=0.018), baseline National Institutes of Health stroke scale (NIHSS) score [median (interquartile range): 10 (6, 14) vs 6 (4, 10), Z= 6.370, P<0.001], depression scale score (14.85±4.16 vs 5.90±1.05, t=14.290, P<0.001), and serum CircRNA_0003694 level (2.42±0.96 vs 1.34±0.38, t=16.384, P<0.001) compared to the non-PSCI group. Conversely, the PSCI group had significantly fewer years of education (6.25±0.91 vs 9.60±1.14, t=4.837, P=0.005) and lower Montreal Cognitive Assessment (MoCA) scores (19.20±2.65 vs 27.30±1.80, t = 13.758, P<0.001) than the non-PSCI group. Multivariate logistic regression analysis showed that older age [odds ratio (OR)=1.647, 95% confidence interval (CI) 1.125-2.694; P=0.028], fwer years of education (OR=1.598, 95%CI: 1.086-2.217; P=0.010), higher mRS Score (OR=1.708, 95%CI: 1.266-3.105; P=0.035), higher baseline NIHSS score (OR=1.925, 95%CI: 1.507-5.204; P=0.016), higher depression scale score (OR=2.308, 95%CI: 1.719-5.926; P<0.001), higher MoCA score (OR=3.107, 95%CI: 2.284-9.280; P<0.001) and increased CircRNA_0003694 levels (OR=2.615, 95%CI: 1.974-7.822; P<0.001) were independent risk factor for PSCI.

Conclusion

The increase of serum CircRNA_0003694 expression level is associated with the occurrence of PSCI in elderly AIS, and is an independent risk factor for PSCI.
