Background: Limited data are available concerning the safety, optimal administration and benefits of contemporary heart failure therapy in patients after left ventricular assist device (LVAD) implantation.
Methods: Between 2015 and 2019, 257 patients underwent LVAD implantation and were included in this observational study. Oral heart failure therapy was initiated and uptitrated during the further course. After propensity matching and excluding patients with immediate postoperative treatment in an affiliated center with different medical standards, hospitalization rates and mortality within 12 months after LVAD implantation were compared between 83 patients who received medical therapy including an angiotensin receptor neprilysin inhibitor (ARNI) and 83 patients who did not receive an ARNI.
Results: The overall use of heart-failure medications after 12 months was high: prescriptions: beta-blockers, 85%; angiotensin inhibiting drugs, 90% (angiotensin-converting-enzyme inhibitors 30%, angiotensin receptor blockers 23%, ARNI 37%); mineralocorticoid receptor antagonists, 80%. No serious drug-related adverse events occurred. The conditional 1-year survival in the group with ARNIs was 97% (95% CI: 94%-100%) compared to 88% in the group without an ARNI (95% CI: 80%-96%); P = 0.06.
Conclusions: Contemporary heart failure therapy is safe in patients with LVADs. No increase in serious adverse events was seen in patients receiving ARNIs. No significant difference in the conditional 1-year survival was seen between the ARNI group and the nonARNI group.
