Summary

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.

Detailed description

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.

Conditions

• Acute Decompensated Heart Failure

Interventions

Type	Name	Description
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.
OTHER	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.
