Heart Failure with Mildly Reduced Ejection Fraction: Therapeutical Considerations and Reasons for This Renaming
Eduardo Thadeu de Oliveira Correia

Introduction
Heart failure (HF) has been classically divided into HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). However, to better classify HF patients with a left ventricular ejection fraction (LVEF) between 41 and 49%, previous guidelines have introduced the term HF with mid-range ejection fraction. Nonetheless, shortly after its formal introduction, HF with mid-range ejection fraction is now called HF with mildly reduced ejection fraction (HFmrEF). In this letter, we explore the reasons behind this renaming and why this change is more important than it may seem.
