Association of Initial Potassium Levels with the Type of Stroke in the Emergency Department
Early differentiation of hemorrhagic stroke from ischemic stroke in patients with suspected stroke is essential for subsequent management of the patient. While serum potassium level has been suggested as a marker of acute hemorrhagic conditions,1, 2 little is known about whether the initial serum potassium levels differ based on the type of stroke. If serum potassium levels can help differentiate hemorrhagic stroke from ischemic stroke, this information can be applied in deciding subsequent treatment procedures (e.g., catheter intervention, tissue plasminogen activator administration, and antihypertensive therapy) in setti...

Serum Glucose and Potassium Ratio as Risk Factors for Cerebral Vasospasm after Aneurysmal Subarachnoid Hemorrhage
Objective: Cerebral vasospasm is associated with poor prognosis in patients with aneurysmal subarachnoid hemorrhage (SAH), and biomarkers for predicting poor prognosis have not yet been established. We attempted to clarify the relationship between serum glucose/potassium ratio and cerebral vasospasm in patients with aneurysmal SAH. Methods: We studied 333 of 535 aneurysmal SAH patients treated between 2006 and 2016 (123 males, 210 females; mean age 59.7 years; range 24-93). We retrospectively analyzed the relationship between cerebral vasospasm grade and clinical risk factors, including serum glucose/potassium ratio.
