Plasma visfatin concentration has been enhanced in ischemic stroke. The aim of the current investigation was to test whether determination of visfatin in plasma is associated with 6-month clinical outcomes including mortality and unfavorable outcome (modified Rankin Scale score>2) in the patients with ischemic stroke. Between July 2009 and January 2012, plasma visfatin concentrations of 186 patients and 100 healthy individuals were quantified by enzyme-linked immunosorbent assay. Plasma visfatin concentrations were higher in patients than in healthy individuals (108.5±41.1 ng/mL vs. 13.8±3.9 ng/mL, P<0.001). A logistic regression analysis selected plasma visfatin concentration as an independent predictor for 6-month clinical outcomes (both P<0.01). Using receiver operating characteristic curve analysis, plasma visfatin concentration was found to predict 6-month clinical outcomes with the high predictive performance. The predictive value of visfatin was in the range of National Institutes of Health Stroke Scale score (both P>0.05). Combined use of visfatin and National Institutes of Health Stroke Scale score did not improve the predictive significance (both P>0.05). Thus, visfatin may help in the prediction of long-term clinical outcomes in patients with ischemic stroke.
