Originally publishedhttps://doi.org/10.1161/CIRCULATIONAHA.122.063642Circulation. 2023;0AbstractBACKGROUND:Recent guidelines proposed a classification for heart failure (HF) on the basis of left ventricular ejection fraction (LVEF), although it remains unclear whether the divisions chosen were biologically rational.
