The aim of our study is to evaluate the contribution of the variation of the LUS score performed at the time of admission (LUS1) and at discharge (LUS2) in predicting the clinical course of patients admitted for acute cardiac decompensation 30 days after discharge.~Delta LUS score=((LUS2-LUS1) *100)/LUS1
prognostic value of delta LUS score of patients hospitalized for acute heart failure within 30 days of discharge.
