Abstract:
Objective:To investigate the correlation between white matter hypertensities (WMHs) and the overall burden of cerebral small vessel disease (CSVD) and clinical outcome of patients with acute ischemic stroke.Methods:From November 2018 to June 2019, patients with acute ischemic stroke hospitalized in the Department of Neurology, the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled prospectively. Their demographic and clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the baseline severity of stroke. The total burden of CSVD was evaluated according to the head MRI findings. The severity of WMHs was assessed based on Fazekas scale. The modified Rankin Scale (mRS) was used to evaluate the outcomes at 90 d after onset. The mRS score 0-1 was defined as good outcome, and ≥2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine independent risk factors for poor outcomes. Results:A total of 153 consecutive patients with acute ischemic stroke were enrolled, of which 126 (82.35%) had a good outcome and 27 (17.65%) had a poor outcome. There were significant differences in age, baseline NIHSS score, lipoprotein-associated phospholipase A 2, total Fazekas score, periventricular WMHs score, and deep WMHs score between the two groups, while there was no significant difference in the total burden of CSVD. Multivariate logistic regression analysis revealed that the baseline NIHSS score (odds ratio 1.245, 95% confidence interval 1.023-1.515; P=0.028) and the total Fazekas score (odds ratio 1.635, 95% confidence interval 1.049-2.549; P=0.030) were the independent risk factors for poor outcomes at 90 d after the onset in patients acute ischemic stroke. Conclusions:The overall burden of CSVD is not associated with the short-term outcomes in patients with acute ischemic stroke. WMHs and baseline NIHSS score are the independent risk factors for poor short-term outcomes in patients with acute ischemic stroke.
