Evaluation of Fibroscan® Performance in Diagnosing Acute Heart Failure in Patients Presenting to the Emergency Department

Обзор

Acute heart failure (AHF) is a major cause of acute dyspnea in emergency departments (EDs), driven primarily by venous congestion, which can lead to hepatic congestion and risk of subsequent liver dysfunction. Current diagnostic tools include clinical evaluation, biomarkers, and imaging (Chest X-Ray or echography), are often limited by delayed results, variability, and suboptimal accuracy in emergency settings. Fibroscan®, a non-invasive device originally designed to assess liver stiffness in chronic liver conditions, has shown potential in detecting liver congestion linked to heart failure. Studies have highlighted significant correlations between liver stiffness measurements (LSM) and markers of venous congestion, such as central venous pressure and adverse outcomes in heart failure patients. Preliminary findings suggest that LSM could provide rapid, bedside insights into systemic congestion, offering a promising avenue for improving diagnostic workflows in acute care. While prior research has mainly focused on chronic heart failure or small study populations, further investigation is needed to explore the utility of Fibroscan® in acute presentations of AHF within EDs. This could help address the limitations of existing diagnostic approaches and enhance patient management in time-sensitive environments.

  The patient will then receive standard medical care, including blood tests and imaging as needed. Once inclusion is confirmed, the patient will undergo a liver stiffness measurement with the Fibroscan® device(Class IIa medical device, CE marked for off-label us) , and the results, including a computed score, will be documented on a separate sheet. The measurement will be performed during the emergency department stay without delaying the initiation of any necessary treatment. The remainder of th

Вторичные конечные точки (1)

• Association between the Liver Stiffness Measurement (LSM) and the score of congestion according to a validated clinical congestion score that ranges from 0 to 9. [Срок оценки: 28 days after inclusion]
