  Purpose
The purpose of this study is to assess the ability of Ultrafiltration to influence the rate of hemodynamic improvement, as measured by the decline in the pulmonary artery occlusion pressure, in patients with NYHA class III/IV Heart Failure.

Condition Intervention Phase
Heart Failure CHF Drug: IV loop diuretic Device: NxStage System One Phase 4

Study Type: Interventional

Primary Outcome Measures:
  • Time Required for the Pulmonary Artery Occlusion Pressure (PAOP) to be Maintained at a Value of Less Than or Equal to 18 mmHg for at Least Four Consecutive Hours (+/- 30 Minutes) During the Intervention Period. [ Time Frame: 4 consecutive hours (+/- 30 minutes) ]

Secondary Outcome Measures:
  • Time to Discharge From the Heart Failure (HF) Unit, and Time to Discharge From the Hospital. [ Time Frame: Time from admission to endpoint achievement ]
  • Total Volume Removal During the Intervention Period [ Time Frame: Intervention start to end. ]
  • Volume Removal Rate. [ Time Frame: Intervention start to end. ]
    Hours of therapy required to remove 1 liter of fluid normalized to body weight.

  • Composite Endpoint of Hospital Readmissions, Emergency Department Visits, and Deaths [ Time Frame: Hospital discharge to 90 days after discharge ]
    Number of patients experiencing at least one of the composite endpoint measures within 90 days of hospital discharge.


Enrollment: 36
Study Start Date: October 2003
Study Completion Date: January 2009
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Ultrafiltration
Patients treated with Extracorporeal Ultrafiltration upon hospital admission for treatment of decompensated heart failure.
Device: NxStage System One
Patients treated with Extracorporeal Ultrafiltration upon hospital admission for treatment of decompensated heart failure.
Active Comparator: Usual & Customary
Patients treated with conventional diuretic therapy upon hospital admission for treatment of decompensated heart failure.
Drug: IV loop diuretic
Use of conventional diuretic therapy upon hospital admission for treatment of decompensated heart failure.

Detailed Description:
This study will be preformed in a specialized heart failure unit at the Cleveland Clinic Foundation (CCF) and will include both the UF-treated group and a control group receiving usual and customary care. Patients will be stratified according to renal function at the time of admission. Therapies will be guided by specific hemodynamic criteria routinely used at the study institution.
