Hyperglycemia and cerebral ischemia

Hyperglycemia is associated with increased complication rate after cardiac surgery and tight glycemic control is established in the postoperative stage. Furthermore, hyperglycemia is particularly harmful to the brain in case of focal ischemia-reperfusion, but to what extent hyperglycemia aggravates the brain damage after cardiac arrest is not clear.

This team investigates the impact of hyperglycemia on ischemic brain injury in terms of focal as well as global insults [1-3]. In 2015, Maria Molnar defended her doctoral thesis, and the current focus is the gene expression profile after hyperglycemic cardiac arrest.
