[Heart Failure With Low and Preserved Left Ventricular Ejection Fraction - are These Two Different Independent Diseases or One Disease, but at Different Stages of its Progression? How Does This Affect the Choice of Therapy and Its Effectiveness?].

The article discusses the question of whether it is possible to conclude that any heart failure (HF), throughout the entire range of left ventricular ejection fractions (LVEF), is a single holistic disease, based on the "external" similarity of treatments for reduced (HFrEF) and preserved (HFpEF) LVEF, and that positioning HFpEF and HFrEF as separate independent diseases is not valid.
