  • Secondary analysis of the PARADIGM-HF and PARAGON-HF randomised trials
  • run-in phases

Authors' conclusion

Moderate eGFR decline when transitioning from RASi to sacubitril/valsartan is not consistently associated with adverse outcomes, and its long-term benefits are retained in heart failure across a broad range of eGFR declines.

Study context

Population
Patients with HF in PARADIGM-HF and PARAGON-HF
Comparison
Sacubitril/valsartan vs renin-angiotensin system inhibitor (RASi), by run-in estimated glomerular filtration rate (eGFR) decline
Primary endpoint
Primary outcomes of each trial, by occurrence of eGFR decline (>15%) during sacubitril/valsartan run-in

Primary result

eGFR recovery · nadir to postrandomization week 16

eGFR partially recovered regardless of sacubitril/valsartan continuation or switch to RASi

Clinical outcomes by initial eGFR decline

Initial eGFR decline not consistently associated with clinical outcomes in either trial
Treatment effect of sacubitril/valsartan consistent across a range of eGFR declines
