The Relationships Between BNP and Neurocardiac Injury Severity Noninvasive Cardiac Output and Outcomes After Aneurysmal Subarachnoid Hemorrhage

摘要

Introduction:Neurocardiac injury, a type of myocardial dysfunction associated with neurological insult to the brain, occurs in 31–48% of aneurysmal subarachnoid hemorrhage (aSAH) patients. Cardiac troponin I (cTnI) is commonly used to diagnose neurocardiac injury. Brain natriuretic peptide (BNP), another cardiac marker, is more often used to evaluate degree of heart failure. The purpose of this study was to examine the relationships between BNP and (a) neurocardiac injury severity according to cTnI, (b) noninvasive continuous cardiac output (NCCO), and (c) outcomes in aSAH patients.
