Abstract: Residual congestion (RC) at discharge predicts adverse outcomes in heart failure with reduced ejection fraction (HFrEF). Its impact on the implementation of guideline-directed medical therapies (GDMT) remains unclear. N-terminal pro-B-type natriuretic peptide (NT-proBNP) trajectory during hospitalisation reflects RC and may be associated with GDMT implementation. The aim was to assess whether discharge NT-proBNP and a fall in NT-proBNP < 30% during hospitalisation (ΔNT-proBNP < 30%) predict GDMT underuse in acute HFrEF. In this prospective observational study, NT-proBNP was measured at hospital admission and 48–72 h before discharge. Provision of individual GDMT drug classes was assessed and GDMT underuse was defined as prescription of <3 key GDMT drug classes at discharge. 391 HFrEF patients (mean age, 69.9 ± 13.1years, 67.3% male) were included. ΔNT-proBNP < 30% was identified in 108 (27.6%). Higher discharge NT-proBNP was independently associated with lower likelihood of prescribing ACE-inhibitors, sacubitril/valsartan, eplerenone/spironolactone, or empagliflozin/dapagliflozin. ΔNT-proBNP < 30% was associated with 17% higher odds of GDMT underuse (95% confidence interval, 1.10–1.31, p < 0.001), regardless of clinical characteristics or in-hospital management. Patients with ΔNT-proBNP < 30% were discharged on lower doses of titratable GDMT medications. In-hospital NT-proBNP burden and trajectory, as markers of RC, are associated with GDMT underutilisation at discharge in acute HFrEF. Addressing RC may impact treatment quality in acute HFrEF.
