“…Investigations suggest that hospital length of stay (LOS) may be a valuable predictor of outcomes for patients hospitalized for ADHF, including rates of early readmission and mortality. On the other hand, other factors, including peripheral edema, chest pain, elevated jugular venous pressure, increased weight during hospitalization, anemia, renal insufciency, and diuretic dose at admission, as well as some laboratory parameters such as serum albumin, sodium, creatinine, and cardiac troponin level are reported to be associated with longer LOS in patients with ADHF [7][8][9][10]. Accordingly, the infammatory status and severity of congestion at admission have been reported to be key factors in predicting the LOS in ADHF [11].…”
