Initiation of sacubitril/valsartan shortly after hospitalisation for acutely decompensated heart failure in patients with newly diagnosed (de novo) heart failure: a subgroup analysis of the TRANSITION study

Eur J Heart Fail. 2020 Feb;22(2):303-312. doi: 10.1002/ejhf.1670. Epub 2019 Dec 9.


Aims: Sacubitril/valsartan has shown efficacy and tolerability in patients with heart failure (HF) and reduced ejection fraction (HFrEF) in the ambulatory setting (PARADIGM-HF), and following stabilisation of acutely decompensated HF (ADHF) (PIONEER-HF and TRANSITION). However, data are lacking for the initiation of sacubitril/valsartan in newly diagnosed (de novo) HFrEF. Here, we assess the tolerability of initiating sacubitril/valsartan following ADHF in TRANSITION subgroups of patients with a de novo vs. prior diagnosis of HFrEF.

Methods and results: TRANSITION randomised 1002 patients to pre- and post-discharge initiation of sacubitril/valsartan (analysis set n = 991, following exclusions for mis-randomisation). In this post-hoc analysis, tolerability to sacubitril/valsartan [proportion of patients achieving target dose (97/103 mg b.i.d.) at 10 weeks post-randomisation], adverse events (AEs) and serious AEs (SAEs) were compared in de novo (n = 286) and prior HFrEF (n = 705) subgroups. More de novo than prior HFrEF patients achieved target dose at Week 10 (56% vs. 45%; relative risk ratio 1.30, 95% confidence interval 1.12-1.52, P < 0.001), and fewer had SAEs and permanent treatment discontinuations. Initiation of sacubitril/valsartan did not prevent the concomitant initiation and up-titration of guideline-directed HF therapies. De novo patients showed faster and greater decreases in N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin-T, and lower rates of HF and all-cause rehospitalisation vs. prior HFrEF.

Conclusions: After ADHF, first-line initiation of sacubitril/valsartan in de novo HFrEF, alongside the initiation of other guideline-directed therapies, is feasible and is associated with a better risk-benefit profile than in patients with prior HFrEF. Early intervention with sacubitril/valsartan may be considered to delay disease progression in patients with de novo HFrEF.
