Overview
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.
Detailed Description
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.

Arms & Interventions
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
Intervention: Isolated veno-venous ultrafiltration (AQ)
IV Loop Diuretics (LD)
Excess fluid from the patient is removed by IV (Intravenous) loop diuretic treatment
Intervention: IV Loop Diuretics (LD)
Outcomes
Primary Outcomes

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
