Abstract:
Objective:To investigate the relationship between serum uric acid (SUA) and 3-month outcomes in patients with acute ischemic stroke undergoing intravenous thrombolysis.Methods:A total of 386 patients with acute ischemic stroke received intravenous thrombolysis therapy from 1 January 2017 to 31 December 2019 in the Affiliated Hospital of Lianyungang, Xuzhou Medical University were enrolled prospectively. The National Institute of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The functional outcome was evaluated by the modified Rankin Scale at discharge or 3 months after onset. Pearson′s correlation was used to assess the relationship between SUA and NIHSS scores at baseline and discharge. Propensity score matching was used to balance confounding factors. Multivariate logistic regression model was used to identify the correlation between SUA and prognostic outcome after thrombolysis.Results:A total of 386 eligible patients were included. Two hundred and thirty patients (59.6%) had good outcomes in the follow-up after 3 months. The levels of SUA are negatively associated with the NIHSS score at discharge ( r=-0.171, P=0.003). A positive correlation was observed between the levels of SUA and the difference of NIHSS at baseline and discharge ( r=0.118, P=0.032). Patients were divided into three groups according to the quartile of SUA. Multivariate logistic regression analysis showed that high SUA levels were independently associated with good outcome three months after stroke ( OR=0.421, 95% CI 0.327-0.541, P<0.001). Conclusion:In patients with acute ischemic stroke, elevated SUA levels can predict better recovery and short-term outcomes in patients undergoing intravenous thrombolysis.
