Effects of sacubitril-valsartan in the treatment of chronic heart failure patients with end-stage renal disease undergoing dialysis

BackgroundThe data on the effects of the angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril-valsartan (LCZ696) in chronic heart failure (CHF) patients with end-stage renal disease (ESRD) requiring dialysis are lacking. This study assessed the efficacy and safety of LCZ696 in CHF patients with ESRD on dialysis. HypothesisLCZ696 treatment can reduce rehospitalization rate for HF, delay the occurrence of rehospitalization for HF, and prolong the survival time. MethodsWe retrospectively analyzed the clinical data of CHF patients with ESRD on dialysis who were admitted to the Second Hospital of Tianjin Medical University from August 2019 to October 2021. ResultsSixty-five patients had primary outcome during the follow-up. The incidence of rehospitalization for HF in the control group was significantly higher than that in the LCZ696 group (73.47% vs. 43.28%, p = .001). There was no significant difference in mortality between the two groups (8.96% vs. 10.20%, p = 1.000). Our study included a time-to-event analysis through 1 year for the primary outcome-Kaplan-Meier curve showed that the LCZ696 group had significantly longer free-event survival time than the control group over 1-year follow-up (median survival time 139.0 days vs. 116.0 days, p = .037). ConclusionsOur study found that LCZ696 treatment was associated with a reduction in HF rehospitalization without significant effects on serum creatinine and serum potassium levels. LCZ696 is effective and safe in CHF patients with ESRD on dialysis.
