Outcomes of hospitalizations for heart failure with reduced ejection fraction complicated by cardiac arrest, stratified by pre-existing implantable cardioverter-defibrillator status
Background: Hospitalizations for heart failure with reduced ejection fraction complicated by cardiac arrest represent a high-risk population, and the role of a pre-existing implantable cardioverter-defibrillator in these patients remains unclear. Methods: We conducted a retrospective observational study using the Nati...
