PG - 639-647 LID - 10.36660/abc.20200250 [doi] AB - BACKGROUND: Ejection fraction (EF) has been used in phenotype analyses and to make treatment decisions regarding heart failure (HF). Thus, EF has become a fundamental part of daily clinical practice. OBJECTIVE: This study aims to investigate the characteristics, predictors, and outcomes associated with EF changes in patients with different types of severe HF. METHODS: A total of 626 severe HF patients with New York Heart Association (NYHA) class III-IV were enrolled in this study. The patients were classified into three groups according to EF changes, namely, increased EF (EF-I), defined as an EF increase >/=10%, decreased EF (EF-D), defined as an EF decrease >/=10%, and stable EF (EF-S), defined as an EF change <10%. A p-value lower than 0.05 was considered significant. RESULTS: Out of 377 severe HF patients, 23.3% presented EF-I, 59.5% presented EF-S, and 17.2% presented EF-D. The results further showed 68.2% of heart failure with reduced ejection fraction (HFrEF) in the EF-I group and 64.6% of heart failure with preserved ejection fraction (HFpEF) in the EF-D group. The predictors of EF-I included younger age, absence of diabetes, and lower left ventricular ejection fraction (LVEF). The predictors of EF-D were absence of atrial fibrillation, lower uric acid level, and higher LVEF. Within a median follow-up of 40 months, 44.8% of patients suffered from all-cause death. CONCLUSION: In severe HF, HFrEF presented the highest percentage in the EF-I group, and HFpEF was most common in the EF-D group.
