Neurogenic pulmonary edema (NPE) is a clinical syndrome characterized by the acute onset of pulmonary edema after a significant central nervous system (CNS) insult. NPE occurs as a result of release of catecholamines into the blood immediately after aneurysm rupture. The aim of this study is to investigate the connection between the value of cardiac biomarkers on admission and incidence of NPE in patients with aneurysmal subarachnoid hemorrhage (SAH).
