Insular Cortical Ischemia Is Independently Associated With Acute Stress Hyperglycemia

Abstract

Despite the small sample size, insular cortical ischemia appeared to be associated with the production of poststroke hyperglycemia. This relationship is independent of pre-existing glycemic status and infarct volume. Neuroendocrine dysregulation after insular ischemia may be 1 aspect of a more generalized acute stress response. Future studies of poststroke hyperglycemia should account for the effect of insular cortical ischemia.
