Abstract:
Objective:To investigate the association of serum uric acid (SUA) with the outcome in patients with acute ischemic stroke (AIS) at one year after onset.Methods:Patients with AIS admitted to the Department of Neurology, Dagang Hospital, Tianjin Binhai New Area were included retrospectively. According to the modified Rankin Scale (mRS) score at 1 year after onset, patients were divided into a good outcome group (0-2) and a poor outcome group (>2). They were also divided into a survival group and a death group based on their survival status at 1 year after onset. The clinical baseline data and laboratory tests were compared. Multivariate logistic regression analysis was used to determine the associations of SUA with poor outcome and death in patients with AIS. Results:A total of 651 patients were enrolled, including 430 males (66.1%) aged 67.5±11.7 years. Four hundred and fourteen patients (63.6%) were in the good outcome group, and 237 (36.4%) were in the poor outcome group. There were 568 patients (87.3%) in the survival group and 43 (16.7%) in the death group. Univariate analysis showed that there were differences in age, atrial fibrillation, history of stroke or transient ischemic attack, baseline National Institutes of Health Stroke Scale (NIHSS) score, and pre-admission mRS score between the poor outcome group and the good outcome group. The homocysteine, SUA, white blood cell count, and creatinine in the poor outcome group were higher than those in the good outcome group, while the red blood cell count and hemoglobin were lower than those in the good outcome group (all P<0.05). There were differences in age, history of ischemic heart disease, atrial fibrillation, history of stroke or transient ischemic attack, baseline NIHSS score, pre-admission mRS score, and stroke etiology classification between the survival group and the death group. Hemoglobin and triglycerides in the survival group were higher than those in the death group, while the white blood cell count and creatinine were lower than those in the death group (all P<0.05). Multivariate logistic regression analysis showed that SUA was an independent risk factor for poor outcome in patients with AIS (odds ratio 1.004, 95% confidence interval 1.001-1.006; P<0.01), but there was no independent correlation with death. Conclusion:Higher SUA is an independent risk factor for poor outcome at one year after onset in patients with AIS.
