HFmrEF – Heart failure with mid-range ejection fraction
Magyar Honvédség Egészségügyi Központ, Kardiológiai Osztály, Budapest
In 2016, the European Society of Cardiology introduced the category of heart failure with mid-range ejection fraction (HFmrEF) besides heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). The primary aim of the introduction of the new category was to inspire research into studying this group of patients. In recent years, the number of studies assessed HFmrEF was multiplied. This review summarizes what is known about epidemiology, clinical characteristics, morbidity and mortality, therapeutic options, the importance of etiological diagnosis and long-term follow up of HFmrEF patients.
