Hyponatremia is predictable in patients with aneurysmal subarachnoid hemorrhage—clinical significance of serum atrial natriuretic peptide

摘要

Purpose Serum atrial natriuretic peptide (ANP) that is elevated after aneurysmal subarachnoid hemorrhage (SAH) causes diuresis and natriuresis (cerebral salt wasting) and might exacerbate delayed ischemic neurological deficit (DIND). We investigated relationships among hyponatremia, serum ANP elevation, and the onset of DIND after SAH.
