Acute Heart Failure - COngestion Discharge Evaluation

This study is evaluating a new method to help doctors decide when heart failure patients are ready to be safely discharged from the hospital. Using lung ultrasound to measure fluid buildup, researchers want to see if this approach better predicts who is at risk of readmission soon after going home. **You may be eligible if...** - You are 18 years or older - You have been admitted to hospital for acute (sudden-onset) heart failure - You are currently considered clinically ready for discharge - You are covered by a social security scheme (French study requirement) **You may NOT be eligible if...** - You have a serious co-existing illness with a life expectancy of 3 months or less - You are on dialysis or have severely reduced kidney function - You have had lung surgery (lobectomy or pneumonectomy) - You have severe lung disease (emphysema, pulmonary fibrosis, etc.) that would interfere with ultrasound imaging - You are pregnant or breastfeeding - You are unable to give consent Talk to your doctor to see if this trial is right for you.
