Short and Long Term Prognosis of Patients Admitted to the ED With Acute Heart Failure

This study is following patients who are admitted to the emergency department with a sudden worsening of heart failure — a condition where the heart cannot pump enough blood to meet the body's needs — to better understand what happens to them in the short term and over the following months. By tracking these patients, researchers hope to identify factors that predict who recovers well and who is at higher risk of complications or readmission. **You may be eligible if...** - You were admitted to the Monastir emergency department with a primary diagnosis of acute heart failure (sudden, severe worsening of heart failure symptoms) - You are willing and able to attend follow-up appointments after your emergency visit **You may NOT be eligible if...** - You are pregnant or breastfeeding - You are not fully conscious or alert (lower level of consciousness on the GCS scale) - You are critically ill and require immediate mechanical support for your heart or breathing - You are unable to understand or follow the study instructions or attend follow-up visits Talk to your doctor to see if this trial is right for you.
