Abstract
BackgroundAlthough elevated body mass index (BMI) is a risk factor for cardiac disease, patients with elevated BMI have better survival in the context of severe illness, a phenomenon termed the "obesity paradox."HypothesisHigher BMI is associated with lower mortality in sudden cardiac arrest (SCA) survivors.MethodsData were collected on 1433 post-SCA patients, discharged alive from the hospitals of the University of Pittsburgh Medical Center between 2002 and 2012. Of those, 1298 patients with documented BMI during the index hospitalization and follow-up data constituted the study cohort.ResultsIn the overall cohort, 30 patients were underweight (BMI
