P4171Population characteristics, interventions and outcomes in hospitalized orthotopic heart transplant patients with sudden cardiac arrest: a nationwide United States analysis from 2007 to 2015

Abstract Background Sudden cardiac arrest (SCA) is a leading cause of death in the United States (US), claiming up to 450,000 lives annually and accounting for ∼25% of deaths following orthotopic heart transplantation (OHT), Purpose We sought to characterize OHT patients suffering SCA and their subsequent management, in comparison to the general, native heart (NH) population, using a large national inpatient database.
