treatment resulted in a mean improvement of 8.05% in (LVEF) in heart failure patients with end-stage kidney disease undergoing dialysis.
Improvement in LVEF was more significant in patients with heart failure with reduced ejection fraction.
Patients receiving ARNI had a 36% lower risk of all-cause mortality compared to conventional treatment.
There was no significant increase in the risk of severe hyperkalaemia or symptomatic hypotension with ARNI treatment.
ARNI treatment also positively affected left ventricular end-systolic diameter, left ventricular mass index, left atrial diameter, and E/e' ratio.

AIMS: (ARNI) has played an increasingly important role in the management of heart failure (HF). However, the evidence on the benefits of ARNI in HF patients with end-stage kidney disease (ESKD) undergoing dialysis is limited. This study aimed to investigate the efficacy and safety of ARNI in patients with concomitant HF and ESKD on maintenance dialysis.
METHODS AND RESULTS: We systematically searched the MEDLINE, Embase, Web of Science, Cochrane, and ClinicalTrials.gov databases for studies reporting outcomes after ARNI treatment in HF patients with ESKD on dialysis. All meta-analyses were performed using the random effects model. Twenty-six studies comprising 2494 patients with concomitant HF and ESKD undergoing dialysis were included. Our synthesis showed a significant improvement in (LVEF) between before and after ARNI treatment (mean change: 8.05%; 95% confidence interval [CI] 5.57-10.54). Compared to the conventional group, the ARNI group showed a greater improvement in LVEF (mean difference: 4.03%; 95% CI 2.90-5.16). This effect was more pronounced in patients with HF with reduced ejection fraction (p < 0.0001). Patients treated with ARNI had a lower risk of all-cause mortality (risk ratio [RR] 0.64; 95% CI 0.45-0.92; p = 0.01) but had a similar rate of HF hospitalization (RR 0.71; 95% CI 0.43-1.18; p = 0.19). ARNI treatment showed benefits in the improvement of left ventricular end-systolic diameter, left ventricular mass index, left atrial diameter, and E/e' ratio (p < 0.05), while it did not significantly increase the risk of severe hyperkalaemia (p = 0.33) or symptomatic hypotension (p = 0.53). interaction
CONCLUSION: This meta-analysis provided insights into the benefits of ARNI in HF patients with ESKD undergoing dialysis by improving left ventricular function, reversing left ventricular remodelling, and reducing the risk of all-cause mortality, without increasing the risk of HF hospitalizations, severe hyperkalaemia, and symptomatic hypotension.
