Improving the Management of Patients with Heart Failure with Reduced Ejection Fraction in Clinical Practice: The Case for Angiotensin Receptor-Neprilysin Inhibitor.

The high risk of adverse outcomes in patients with heart failure with reduced ejection fraction (HFrEF) demands urgent efforts in the initiation of guideline-directed medical therapy to reduce morbidity and mortality. Angiotensin receptor-neprilysin inhibitor showed substantial benefits in reducing the risks of heart failure hospitalisation and cardiovascular mortality in HFrEF patients. Therefore, the European Society of Cardiology 2021 guidelines recommend angiotensin receptor-neprilysin inhibitor as a first-line therapy for HFrEF patients. The guidelines emphasise the importance of the early use and rapid titration of the 'four pillars' in HFrEF: angiotensin receptor-neprilysin inhibitor, β-blockers, sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists. However, real-world application of the guidelines remains suboptimal, limiting patient outcomes. This statement paper investigates the barriers to the use of the 'four pillars', and aims to give guidance to improve their implementation in different HFrEF patient types.
