The optimal length of stay (LOS) in patients hospitalized for acute heart failure (AHF) remains uncertain [1]. Classically, more extended stays have been associated with a higher risk of in-hospital complications, worse prognosis, and, therefore, higher hospitalization expenditures [2,3]. Thus, healthcare providers' initiatives have traditionally focused on decreasing LOS [4]. Nevertheless, a too short LOS has also been associated with an increased risk of early readmission [5,6]. Therefore, there is a need for searching clinical indicators to determine an optimal LOS for HF decompensation [7,8].
