Abstract:
Objective To explore the association of serum bilirubin level at the time of admission with the compos?ite outcome（disability or death）in discharged patients with acute ischemic stroke. Methods In a retrospective cohortstudy from June 1st 2009 to May 31st 2012, we continuously included 3151 patients with acute ischemic stroke and col?lected demography,lifestyle,clinical manifestations and laboratory test data. Functional outcome was measured with themodified Rankin scale (mRS) when subjects were discharged. Disability was defined as mRS≥3 and composite outcomewas defined as mRS≥3 or death. Serum bilirubin was divided into four groups according to the quartile. Multiple Coxregression analysis was used to assess the independent relation between serum bilirubin and disability death and the com?posite outcome. Results There were 407 disabled patients，the disability rate was 12.9%；and 104 patients were dead，the fatality rate was 3.3%.After adjusting for multiple factors, we found the risks of composite outcome with total bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.335(1.047～1.702) respectively；The risks of composite outcome with indirect bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.355(1.062～1.728) respectively; The risks of composite outcome with bilirubin direct in the third and the forth quartile were higher than that in the first quartile, aHR and 95% CI were11.403(1.089～1.807)and 1.431 (1.118～1.833) respectively.With the increase of total bilirubin，indirect bilirubin and direct bilirubin level，the compos?ite outcome of discharged patient was on the increase. Conclusions The study indicated that higher serum bilirubincould increase the risk of composite outcome in ischemic stroke patients, there was dose-response relationship ,and bili?rubin was a independent risk factor.
