Heart failure (HF) is a major cause of morbidity and mortality, with nearly half of all HF‐related deaths resulting from sudden cardiac death (SCD), most often from an arrhythmic event. The pathophysiologic changes that occur in response to the hemodynamic stress of HF may lead to increased arrhythmogenesis. Theoretically, medications that block these arrhythmogenic substrates would decrease the risk of SCD. The combined angiotensin receptor and neprilysin inhibitor (ARNi; tradename Entresto) is the newest commercially available medication for the treatment of heart failure.
