Admission HbA1C in Aneurysmal Subarachnoid Hemorrhage

In patients suffering from aneurysmal subarachnoid hemorrhage (aSAH), hyperglycemia is considered an adverse prognostic factor. Glycated hemoglobin (or HbA1c) can be measured to estimate the average plasma glucose concentration over prolonged periods of time, thus determination of glycated hemoglobin at admission after aSAH serves as an approximation of blood glucose levels in the weeks preceding aneurysm rupture. In this patient registry admission HbA1c, clinical course and neurological outcome after 6 month are recorded, to determine whether elevated blood glucose levels prior to aneurysm rupture influence the clinical course and patient outcome after aSAH.
