Angiotensin receptor-Reprilysin inhibition improves blood pressure and heart failure control in left ventricular assist device patients

Angiotensin receptor-neprilysin inhibitors (ARNIs) greatly benefit functional capacity and longevity in heart failure with reduced ejection fraction (HFrEF). Angiotensin receptor-neprilysin inhibitors remain underutilized and unstudied, however, in left ventricular assist device (LVAD) recipients, in spite of their underlying HFrEF. In this case series, we studied the feasibility and short-term efficacy of ARNI utilization in 21 LVAD patients. Angiotensin receptor- neprilysin inhibitor initiation was successful in most, resulting in significant consolidation of blood pressure (BP) medical management and marked improvements in both functional capacity and diuretic requirements. Angiotensin receptor-neprilysin inhibitors are safe, feasible, and within a short timeframe benefit BP and heart failure control in LVAD recipients.
