OBJECTIVE The relationship between serum uric acid (SUA) and the risk of ischemic stroke (IS) has been fully elucidated in previous studies. Therefore, we further investigated the relationship between SUA levels and the risk of IS. PATIENTS AND METHODS 2195 patients at the Beijing Hospital, between February 2012 and May 2018, were enrolled in our hospital-based cross-sectional study. The patients were divided into an IS group and a (non-IS) control group, based on their medical records. SUA level was measured using the enzymatic uricase method. Univariate and multivariable logistic regression models were used for the analysis. RESULTS A total of 300 patients with IS [176 men; age (mean ± SD): 71.38 ± 10.66 years] and 1895 control patients [1060 men; age (mean ± SD): 66.12 ± 12.04 years] were enrolled in this study. IS patients had higher concentrations of SUA, compared with control group patients [6.11 ± 1.92 vs. 5.77 ± 1.62 (mg/dL)]; P = 0.004). We observed a J-shaped association between SUA levels and the risk of IS. Both the univariate and multivariate logistic regression analyses found a significantly elevated risk of IS in the bottom and upper SUA levels both in quartiles and deciles, compared with the intermediate SUA levels. CONCLUSION These results indicate a J-shaped, independent association between SUA levels and the risk of IS in high-risk individuals.
