Abstract
BACKGROUND: The role of serum uric acid (SUA) in affecting outcomes after endovascular treatment (EVT) in patients with ischemic stroke remains unclear. This study investigated the association of SUA with outcomes of patients with acute large vessel occlusion (LVO) who had received EVT. METHODS: Patients with acute LVO stroke who underwent EVT within 24 hours were enrolled from a prospective, nationwide registry study. Baseline characteristics and SUA level within 24 hours of EVT were collected. The primary outcome was an excellent 90-day functional outcome [modified Rankin Scale (mRS) score 0-1]. Secondary outcomes included a favorable 90-day outcome (mRS score 0-2), symptomatic intracranial hemorrhage (sICH), and 90-day mortality. The SUA level was analyzed in quartiles and as a continuous variable. We investigated the independent association of SUA with the primary outcome using multivariable logistic regression. RESULTS: Among 780 patients (mean age 64 years; 66.28% males), 230 (29.49%) had an excellent 90-day outcome. A higher SUA level was significantly associated with an excellent outcome in univariate logistic regression (P=0.045) and after adjusting for confounders in multivariate analysis [adjusted odds ratio (aOR), 0.998; 95% confidence interval (CI), 0.996-1.000; P=0.018]. Multivariate logistic regression analysis showed patients with SUA level in the fourth quartile had an excellent 90-day outcome (aOR, 0.367; 95% CI, 0.154-0.876; P=0.024). There was no significant association for SUA level with favorable 90-day outcome, sICH, or 90-day mortality (P>0.05). CONCLUSIONS: Among patients with acute LVO type of stroke who received EVT, baseline high SUA level may predict a better 90-day functional outcome.
