Brief Summary:
The purpose of the research is to determine if patients have fewer Heart Failure (HF) events after receiving Aquapheresis (AQ) therapy compared to intravenous (IV) diuretics up to 90 days of discharge from the hospital. Heart Failure events are defined as returning to the hospital, clinic or emergency department (ED) for treatment of HF symptoms.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Heart Failure Cardiac Failure Acute Decompensated Heart Failure (ADHF) | Device: Isolated veno-venous ultrafiltration (AQ) Drug: IV Loop Diuretics (LD) | Not Applicable |
The aim of the proposed AVOID-HF study is to confirm and expand the findings that fluid removal by AQ reduces HF rehospitalizations at 90 days as well as the length of these HF rehospitalizations. In the "Ultrafiltration Versus Intravenous Diuretics for Patients Hospitalized for Acute Decompensated Heart Failure" (UNLOAD) study, the 90 day HF re-hospitalizations were pre-specified secondary end-points. AVOID-HF is designed with a primary end-point to determine if AQ reduces the number of HF events (Rehospitalization or unscheduled outpatient or emergency room treatment for HF) after discharge from index hospitalization compared to IV loop diuretics. AVOID will also explore days alive and out of the hospital as a secondary end-point, which was not done in UNLOAD. In other words, the AVOID-HF study is going beyond studying only the amount of fluid removal and will explore whether the modality of fluid removal influences HF outcomes.

Experimental: Aquapheresis (AQ) - isolated veno-venous ultrafiltration
Excess fluid from the patient is removed by isolated veno-venous ultrafiltration treatment using the Aquadex Flex Flow System
|
Device: Isolated veno-venous ultrafiltration (AQ)
Aquapheresis treatment (isolated veno-venous ultrafiltration) using the Aquadex FlexFlow System during index hospitalization until the patient's signs and symptoms of fluid overload have improved to the satisfaction of the treating physician. Ultrafiltration rates, duration and frequency of treatment are dependent on the amount of patient fluid excess and on the rate of fluid movement from the interstitial spaces into the vascular compartment during Aquapheresis (Plasma Refill Rate, or PRR)

Active Comparator: IV Loop Diuretics (LD)
Excess fluid from the patient is removed by IV (Intravenous) loop diuretic treatment
|
Drug: IV Loop Diuretics (LD)
IV Loop Diuretics treatment using only FDA approved IV loop diuretics indicated for the treatment of patients with fluid overload. This includes furosemide or other IV loop diuretics administered at equivalent doses to furosemide. Patients will receive either a twice daily IV bolus or continuous IV LD infusions according to the high dose protocol of the"Diuretic strategies in patients wth acute decompensated heart failure" (DOSE) trial.
Other Name: furosemide |
Primary Outcome Measures :
- Time to First Heart Failure (HF) Event [ Time Frame: 90 days after discharge from index HF hospitalization. ]
Time to first HF event within 90 days after discharge from index HF hospitalization. HF events are defined as
- HF rehospitalization or
- unscheduled outpatient or emergency room treatment with IV loop diuretics or
- unscheduled outpatient Aquapheresis treatment
Secondary Outcome Measures :
- EFFICACY: Total Fluid Removed During the Index Hospitalization [ Time Frame: Index Hospitalization, an average of 8 days ]AQ-Fluid removed by AQ plus urine voided versus urine voided when treated with IV diuretics
- EFFICACY: Net Fluid Removed During the Index Hospitalization [ Time Frame: Index Hospitalization, an average of 8 days ]AQ-Fluid removed by AQ plus urine voided minus fluid intake versus urine voided minus fluid intake with the IV diuretics.
- EFFICACY: Weight Loss at 72 Hours After Initiation of Treatment [ Time Frame: 72 hours after treatment initiation ]Weight at 72 hours after treatment initiation minus weight at treatment initiation. Negative mean values indicate weight loss.
- EFFICACY: Total Weight Loss During the Index Hospitalization [ Time Frame: Index Hospitalization, an average of 8 days ]Weight at hospital discharge minus weight at hospital admission. Negative mean values indicate weight loss.
- EFFICACY: Time to Freedom From Congestion [ Time Frame: Index Hospitalization, an average of 8 days ]Time from hospital admission to time patient is free of congestion in the hospital. Freedom from congestion is defined as jugular venous distention of < or equal to 8 cm, with no orthopnea and with trace peripheral edema or no edema. Measurement taken every 24 hours after treatment initiation.
- EFFICACY: Freedom From Congestion [ Time Frame: Index Hospitalization, an average of 8 days ]Defined as jugular venous distention of < or equal to 8 cm, with no orthopnea, and with trace peripheral edema or no edema at hospital discharge

Scores were transformed to a range of 0-100, in which higher scores reflect better health status.
- CLINICAL: Global Clinical Score at 30 and 90 Days After Discharge [ Time Frame: Within 90 days after hospital discharge ]KCCQ Questionnaire analysis based on patient's self-assessment of how they feel at various intervals compared to how they felt prior to index treatment.
