ALB and hydrops fetalis: Several studies explored the prognostic values of various score systems in patients with acute HF: sequential organ function assessment score (SOFA) and ACUTE HF scores combined clinical, biomedical, and echocardiographic indexes to predict short- or long-term outcomes (22, 23); Norton score system, a tool to assess frailty had been studied in risk stratification (24); and albumin-bilirubin (ALBI) score reflecting liver function was also been discovered to associate with 1-year mortality (25).
