Abstract

It is unclear whether 25-hydroxyvitamin D [25(OH)D] has a protective effect on long-term prognosis of ischemic stroke and whether it is affected by blood glucose levels. We aim to examine the effect of serum vitamin D especially its deficiency on 1-year poor outcome of ischemic stroke patients in total patients and by blood glucose subgroups. A total of 3041 ischemic patients from China Antihypertensive Trial in Acute Ischemic Stroke were included. The serum concentrations of 25(OH)D were measured at baseline. All subjects were followed up for death and vascular events at 1year after acute ischemic stroke. Among total ischemic stroke patients and those with hyperglycemia, 25(OH)D deficiency was not associated with the risk of vascular events and death. In the normoglycemic subgroup, 25(OH)D deficiency subjects had a significantly higher risk of poor prognosis compared with those with 25(OH)D≥20ng/ml. The hazard ratio (95% confidence interval) was 1.58(1.04-2.41) in the multivariable adjusted model (P for linear trend=0.02). Serum 25(OH)D deficiency may be merely an independent risk factor of 1-year poor prognosis in ischemic stroke patients without hyperglycemia. Future studies about improving long-term prognosis of ischemic st...Continue Reading
