In a real-world population of Korean patients with heart failure with reduced ejection fraction (HFrEF) and end-stage renal disease (ESRD) on haemodialysis, sacubitril/valsartan has demonstrated significant benefits vs renin-angiotensin system (RAS) blockade in reducing all-cause mortality and any hospitalization.
Using 2017–2021 data from the Korean National Health Insurance Service database, researchers identified 2,248 eligible patients who received sacubitril/valsartan and 2,528 eligible patients who received RAS blockade for comparison of a composite primary outcome of all-cause mortality or any hospitalization by inverse probability treatment weights.

Results showed a significantly lower risk of all-cause mortality or any hospitalization at 2 years with sacubitril/valsartan vs RAS blockade (hazard ratio [HR], 0.74; 95 percent confidence interval [CI], 0.75–0.96; p=0.009).
Significant risk reductions were also observed with sacubitril/valsartan in all-cause mortality (HR, 0.74; 95 percent CI, 0.59–0.93; p=0.008) and any hospitalization (HR, 0.85; 95 percent CI, 0.75–0.95; p=0.007).
“The benefits of sacubitril/valsartan vs RAS blockade were more definite in the subpopulation of patients with a proportion of days covered ≥80 percent,” the researchers pointed out. In these patients, HRs for all-cause mortality, cardiovascular (CV) mortality, and any hospitalization were 0.61 (95 percent CI, 0.46– 0.80; p<0.001), 0.59 (95 percent CI, 0.43–0.82; p=0.001), and 0.80 (95 percent CI, 0.80–0.94; p=0.007), respectively.
“The results suggest the importance of medication adherence in improving CV outcomes,” the researchers commented.
