Objective: Admission measures of stroke severity are often used to assess 30-90 day outcomes. Since some patients have a poor outcome by discharge, we sought to identify a biomarker that distinguishes severities as well as acute outcomes. Disruptions in the equilibrium of the redox system were used as an indicator of stroke severity and acute outcome.
Methods: Oxidation reduction potential (ORP), a measure of the redox system, was assessed in plasma at admission and 24 h later in patients admitted with stroke symptoms (n=76). Overall differences in ORP between stroke patients and healthy controls were determined. Within stroke patients, changes in ORP as a function of hospital discharge status, modified Rankin scale and NIHSS were assessed using ANOVA and the ability to predict acute outcome in ischemic stroke patients based on ORP was compared..
