Abstract
BACKGROUND: An association between serum uric acid and outcomes of ischemic stroke has been reported, but the results are controversial. The aim of this study is to clarify how uric acid may affect activities of daily living after acute ischemic stroke. METHODS: Consecutive Japanese patients with acute ischemic stroke were analyzed. Serum uric acid quartiles and activities of daily living at hospitalization and discharge in men and women were examined. Activities of daily living were evaluated using the modified Rankin scale score, and a score of 3 or higher was defined as poor activities of daily living. P values less than .05 were considered significant. RESULTS: A total of 987 patients with acute ischemic stroke (591 men; mean age, 72.3 years) were analyzed in this study. We observed a U-shaped relationship between serum uric acid and poor activities of daily living in both men and women at hospitalization and discharge. Multivariate analysis demonstrated that the first quartile group of serum uric acid was significantly associated with poor activities of daily living in both men and women, using the third quartile group as the reference. CONCLUSIONS: Lower serum uric acid can be a marker for predicting poor activities of daily living in patients with acute ischemic stroke, irrespective of sex.
