prognostic value of delta LUS score of patients hospitalized for acute heart failure within 30 days of discharge.

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

Inclusion Criteria:

• Patients aged over 18 years,
• Patients hospitalized in the emergency department for dyspnea having as etiology an acute heart failure and in whom will be performed two pulmonary ultrasound examinations (at entry and exit).

Exclusion Criteria:

• Age less than 18 years
• Dyspnea of non-cardiac etiology (cause: pulmonary, traumatic, toxic...)
• Altered state of consciousness (Glasgow score<14)
• Hemodynamic instability: presence of peripheral signs of shock, use of vasoactive drugs
• Mechanical ventilation from the outset
• Cardiorespiratory arrest
• Inability to give consent to the study
• Missing one of two ultrasound examinations
• Unable to make telephone contact after one month.

This is a prospective observational study that will be conducted in the emergency department of CHU Fattouma Bourguiba Monastir over a period from March 2023 to December 2023.

Will be included in this study patients aged over 18 years, hospitalized in the emergency department for dyspnea having as etiology an acute heart failure and in whom will be performed two pulmonary ultrasound examinations (at entry and exit). These patients will be contacted after one month of their discharge from the hospital
