Abstract:Objective To collect clinical data of lacunar infarction patients, and to study the risk factors for vascular cognitive impairment (VCI) after lacunar infarct. Methods Collected clinical and laboratory data of 156 lacunar infarction patients, apply National Institute of Health stroke scale (NIHSS) and the Montreal cognitive assessment scale (MoCA) to evaluate neurological function and cognitive impairment. Multivariate Logistic regression analysis was used to screen the risk factors for VCI after lacunar infarction among the clinical data and blood plasma homocysteine concentration. Results 62.18% of patients occurred VCI. Multivariate Logistic regression analysis showed that infarct in critica (Ol ^ R=5.937, 95% CI=1.086, 32.458), white matter hyperintensity (WMH) (Ol ^ R=5.948, 95% CI=1.234, 28.672) and blood plasma homocysteine concentration (Ol ^ R=4.389, 95% CI=1.039, 18.535) were independent risk factors for VCI in patients with lacunar infarct (P < 0.05). In addition, MoCA score and blood plasma Hcy concentration was negative correlated negatively (r = -0.694, P < 0.05). Conclusions Infarct in critica, white matter hyperintensity (WMH) and blood plasma homocysteine concentration were independent risk factors for VCI in patients with lacunar infarct.
