Abstract only Introduction: Recent studies showed that patients with chronic heart failure with recovered ejection fraction (HFrecEF) have better clinical outcomes than those with preserved ejection fraction (HFpEF). However, there is lack of data about HF prognosis according to EF change in acute heart failure (AHF). Therefore, the aim of this study was to investigate the prognosis of HFrecEF compared to HFpEF in patients with AHF. Methods: A total of 5,625 cohort patients with AHF enrolled in Korean AHF registry (KorAHF). Of them, 2,632 patients underwent follow-up echocardiography with measurement of EF. They were divided into three groups according to EF change: HF with reduced EF (HFrEF) (n=1,522, 68.6±14.5 years, 818 males), HFpEF (n=281, 72.6±13.5 years, 115 males), and HFrecEF (n=829, 67.6±14.2 years, 341 males). HFrEF was defined as AHF patients with EF =50%, and HFrecEF as EF>=50% with previous EF
