Clinical characteristics and outcomes of neurogenic stress cadiomyopathy in aneurysmal subarachnoid hemorrhage

Abstract: Background: Aneurysmal subarachnoid hemorrhage (aSAH) is an often devastating form of stroke. Aside from the initial hemorrhage, cardiac complications can occur resulting in neurogenic stress cardiomyopathy (NCM), leading to impaired cardiac function. We investigated whether aSAH patients with NCM had poorer long term functional outcomes than patients without NCM. Mortality, vasospasm, and delayed ischemic complications were also evaluated.Methods: A retrospective study of all patients admitted for aneurysmal subarachnoid hemorrhage (aSAH) from January 2006 to June 2011 (n=299) was conducted. Those patients who underwent an echocardiogram were identified (n=120) and were assigned to the NCM (n=49) category based on echocardiographic findings defined by a depressed ejection fraction (EF%) along with a regional wall motion abnormality (RWMA) in a non-vascular pattern. Primary outcome measures included in-hospital mortality and functional outcomes as measured by the Modified Barthel Index (mBI) at 3 months and one year. Secondary analysis determined if there was an association between NCM, cerebral vasospasm and delayed cerebral ischemia.Results: 16% of aSAH patients developed NCM. Mortality was higher (p
