DESIGN:
A prospective, multicenter, observational cohort study including 580 patients admitted for acute decompensated heart failure (ADHF).
Ultrasound assessment of congestion (VExUS and LUS) will be performed serially during admission: within 48 hours of admission, at the time diuretic therapy is switched from intravenous to oral, and on the day of discharge. The discharge assessment will serve as the primary predictor.
Treating physicians will be blinded to all ultrasound findings. Patients will be followed for 90 days by telephone follow-up and chart review for the primary endpoint, with extended chart review at one year for selected secondary endpoints.
AIMS:
To determine whether combined ultrasound assessment of venous (VExUS) and pulmonary congestion (LUS) at discharge predicts heart failure readmission and all-cause mortality in patients hospitalized with ADHF.
HYPOTHESIS:
Abnormal VExUS and/or LUS findings at discharge are associated with a higher risk of heart failure readmission and all-cause mortality after 90 days.

| Composite of heart failure readmission and all-cause mortality | Time-to-event analysis. Endpoints appointed by a blinded adjudication committee. Abnormal VExUS will be defined according to criteria from our ongoing validation study. Abnormal LUS is defined as ≥3 B-lines in ≥2 scanning zones per hemithorax (8-zone method) or ≥15 total B-lines overall. | 90 days |
| Measure | Description | Time Frame |
|---|---|---|
| Days alive and out of hospital | Days alive and out of any hospital within 90 days and 1 year, indexed to discharge; death counts as 0 days. Computed over the complete fixed window using chart-based ascertainment of vital status and admissions. Patients censored early for reasons other than death (e.g. withdrawal) are handled by censoring or exclusion (not scored 0, since 0 denotes death). Analyzed with rank-based methods given the zero-spike and skew. |

| Within 90 days and one year after discharge |
| Individual components of the primary endpoint | 90 days and one year after discharge |
| Association between discharge VExUS and markers of congestion | Markers of congestion: Objective markers (jugular venous pressure, peripheral edema, pulmonary rales, and weight change), NT-proBNP, renal function, and echocardiographic measures of cardiac function. | At discharge |
| Incremental prognostic value of discharge VExUS and LUS beyond standard clinical assessment of congestion for predicting 90-day and one-year heart-failure readmission and all-cause mortality | 90 days and 1 year |
| Post-discharge diuretic use | Defined as the change in loop diuretic dose (furosemide-equivalent) from discharge to 30- and 90-day follow-up, and occurrence of diuretic intensification (dose increase or addition of thiazide-type diuretic) within 90 day | 90 days |
