Disrupted congestion in acute heart failure: can ultrasound at discharge predict readmission and death

Official title: Assessment of Residual Congestion in Acute Decompensated Heart Failure

Run by University of Aarhus · NCT07682298 · Data updated 2026-11-12

This study tests whether ultrasound checks of congestion at discharge can predict which patients with acute heart failure are more likely to be readmitted or die within 90 days.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older hospitalized for acute decompensated heart failure with clinical congestion and requiring IV loop diuretics.

Probably not a fit

Patients without discharge ultrasound abnormalities or those not at risk for readmission may derive little predictive benefit from the test results.

What this trial studies

This is a prospective, multicenter, observational cohort enrolling up to 580 adults with acute decompensated heart failure. Serial ultrasound assessments of congestion using VExUS and lung ultrasound (LUS) are performed within 48 hours of admission, at the switch from IV to oral diuretics, and on discharge, with discharge findings serving as the primary predictor. Treating clinicians are blinded to ultrasound results, and patients are followed by phone and chart review for 90 days, with extended follow-up at one year for selected outcomes. The goal is to determine if abnormal discharge ultrasound findings correlate with higher risks of heart failure readmission or all-cause mortality. No interventional treatment is tested in this observational design.

Why it matters

Potential benefit: If successful, discharge ultrasound could help identify patients at higher risk for adverse outcomes so clinicians can tailor post-discharge care.

How similar studies have gone: Previous studies using ultrasound-based congestion assessment have shown promise for risk stratification in heart failure, supporting further validation in this design.
