The purpose of this research study is to compare the effects (good and bad) of ultrafiltration treatment with standard intravenous (in your vein) diuretic therapy (furosemide, torsemide, bumetanide) on your heart function and blood flow.
Acute Decompensated Heart Failure
Drug: Loop diuretics (furosemide, torsemide, bumetanide)
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Diagnostic
||A Randomized Controlled Pilot Study for Assessment of Coronary Flow Reserve With Cardiac PET Imaging in Acute Decompensated Heart Failure Patients Treated With Diuretics Versus Ultrafiltration
Primary Outcome Measures:
- Myocardial Blood Flow [ Time Frame: 1 - 5 days ] [ Designated as safety issue: No ]
Evaluate the effects of ultrafiltration (UF) compared to intravenous diuretic therapy on myocardial blood flow (MBF) and coronary flow reserve (CFR), as assessed by positron emission tomography (PET), in patients with acutely decompensated heart failure (ADHF).

||May 2013 (Final data collection date for primary outcome measure)
Active Comparator: Ultrafiltration
Patients with acute decompensated heart failure will be randomized to either ultrafiltration or diuretics (loop diuretics: furosemide, bumetanide, and/or torsemide). Patients in this arm are randomized to ultrafiltration.
Subjects will be randomized with a computer generated random number function to either ultrafiltration or diuretic therapy within 24 hours of hospitalization or outpatient heart failure clinic for the management of fluid overload. If randomized to the ultrafiltration arm, on admission to the hospital patients will be initiated on ultrafiltration therapy for 2-5 days.
Patients randomized to UF will be treated using the Aquadex System 100 ultrafiltration device (CHF Solutions, Minneapolis, MN). The selection of ultrafiltration rate (fluid removal rate)will be determined by the treating physicians based upon clinical assessment of volume status and perceived safety.
Other Name: Aquadex System 100 ultrafiltration device
Active Comparator: Diuretic Therapy
Patients with acute decompensated heart failure will be randomized to either ultrafiltration or diuretic therapy ((loop diuretics: furosemide, bumetanide, and/or torsemide). The myocardial blood flow of patients treated with ultrafiltration will be actively compared to diuretic therapy with either furosemide, bumetanide, and/or torsemide.
Drug: Loop diuretics (furosemide, torsemide, bumetanide)
Patients with ADHF and hypervolemia will be enrolled in a prospective, randomized fashion.
Subjects will be randomized with a computer generated random number function to either ultrafiltration or diuretic therapy within 24 hours of hospitalization for the management of fluid overload.
Patients randomized to diuretic therapy will be treated with intravenous loop diuretics (e.g. furosemide, bumetanide, torsemide). The selection of diuretic, dose and frequency of diuretic administration will be determined by the treating physicians based upon clinical assessment of volume status, response to medication, and perceived safety.
- Lasix, furosemide
- Bumex, bumetanide
- Demadex, torsemide
The standard of care to treat congestive heart failure is with a class of medication called diuretics, which remove the extra fluid from the body through urination. Another way to remove extra fluid in patients with heart failure is called ultrafiltration. Ultrafiltration may result in more rapid removal of excess fluid and more rapid improvement in your symptoms compared to standard diuretic treatment. Currently, it is unknown what effects these therapies (diuretics or ultrafiltration) have on the small blood vessels in your heart. These small blood vessels are important to supply blood and oxygen to your failing heart. Thus, the purpose of this research study is to compare the effects (good and bad) of ultrafiltration treatment with standard intravenous (in your vein) diuretic therapy on your heart function and blood flow.
