The Relationship Between Ionized Calcium Levels and Prognosis in Patients with Spontaneous Subarachnoid Hemorrhage

The serum calcium plays a role as a cofactor in critical steps such as cardiac contractility, vascular tone, and the coagulation cascade. This study aimed to determine if the level of ionized calcium can predict outcomes in patients with spontaneous subarachnoid hemorrhage (SAH) in the emergency department.
