Background and purpose: As uncertainty persists over the prognostic significance of low estimated glomerular filtration rate (eGFR) in acute stroke, the effects of low eGFR on death/disability amongst participants with acute stroke in China were determined. Methods: Nanjing First Hospital stroke registry was a prospective cohort study of stroke patients. Patients with acute stroke (brain infarction, intracerebral hemorrhage or subarachnoid hemorrhage) within 7 days of onset were recruited consecutively from 2004 to 2008. Baseline eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equation. Outcomes were death/disability, defined by scores 3-6 on the modified Rankin Scale at 90 days. Results: A total of 1909 participants were included in the present analyses. Of them, 112 (5.9%) had baseline moderate to severe decrease in eGFR (G3b-4) and increasing risk of higher National Institutes of Health Stroke Scale (NIHSS) scores. Low eGFR was associated with increasing risk of death/disability at 90 days [G3b-4, odds ratio 2.58 (95% confidence interval 1.71-3.91); G3a, 1.86 (1.35-2.56); G2, 1.21 (0.96-1.52); P trend <0.001). However, the association was not statistically significant after adjustment for demographic and clinical factors including NIHSS scores. Conclusions: There were no appreciable effects of low eGFR on death/disability at 90 days independent of other prognostic factors in Chinese patients with acute stroke.
