Eligibility Criteria
Inclusion
- Patients hospitalized due to decompensated heart failure who require IV inotropic and/or vasodilator and diuretic therapy
- Patients receiving appropriate medical therapy for heart failure, defined as ACE inhibitors and beta blockers (all unless not tolerated or contraindicated) and diuretics, for 1 month prior to study entry
- For at least 24 hours prior to inclusion into the study, the patient should be treated with a minimum dose of the following: dobutamine 2.5μg/kg/min or milrinone 0.3μg/kg/min or dopamine 5μg/kg/min. or nesiritide 0.01μg/kg/min or nitroglycerin 0.3 µg/kg/min or nitroprusside 0.3 µg/kg/min or a combination of any of these agents, with diuretic therapy. Doses of the above stated medications should be stable for 6 hours prior to inclusion into study. An increase in this dosage within the first 8 hours after enrollment is determined by the attending physician to be unlikely and the following definition of "not responding adequately to IV inotropic and/or vasodilator and diuretic therapy" is exhibited:
- PCWP is ≥ 20 mmHg at time of randomization and PCWP was ≥ 18 mmHg continuously for 24 hours or PCWP ≥ 20 mmHg continuously for 12 hours prior to randomization.
- Cardiac Index \< 2.4 L/min/m2
- There is evidence for abnormal renal function and/or diuretic resistance defined as: Serum creatinine \> 1.2 mg/dL or Diuretic dosage of intravenous Furosemide ≥ 120 mg daily, or equivalent
- LVEF \< 35%
- Male or female 18-90 years of age
- If female, no child-bearing potential or negative pregnancy test
- Written informed consent
- Willingness to participate in required follow-up exams
Exclusion
- Acute Q-wave myocardial infarction within past 7 days
- Post cardiotomy shock within past 30 days
- Cardiac surgery within past 14 days
- Bridge to transplant
- History of severe COPD as defined as FEV1 \< 1.0 liter
- History of malignant arrhythmias defined as either:
- sustained ventricular tachycardia \> 15 beats or more in length, not associated with a correctable cause, within the preceding 3 months, unless the patient presently has an implantable cardiac defibrillator.
- history of ventricular fibrillation or sudden death, unless the patient presently has an implantable cardiac defibrillator
- Patients implanted with a resynchronization device within the previous 14 days or if there is a possibility of implant within 60 days following randomization
- Systolic pressure \<80 mmHg
- Requiring cardiopulmonary support type devices
- Platelets \< 50,000/mm3 or other evidence of coagulopathy, INR greater than 1.5 in the absence of anticoagulation therapy.
- Infection (WBC ≥ 12.5 x 103/ml, and or temperature ≥ 100.5°F/38°C)
- History of cerebral vascular accident (CVA) or transient ischemic attacks (TIA) within the last 3 months
- Unwilling or unable to receive blood transfusion
- Inability to undergo treatment with heparin
- Patients on dialysis or serum creatinine \> 4.0 mg/dl
- Primary liver disease with bilirubin, SGOT, or SGPT \> 4X upper limit of normal
- Life expectancy from other disease \< 12 months
- Patients who are active on the cardiac transplantation waiting list, unless there is a documented reason (large body habitus, highly sensitized, O blood group) to anticipate that transplant is unlikely within the subsequent 65 days.
- Symptomatic patent foramen ovale or intracardiac shunt
- Patients diagnosed with clinically significant peripheral vascular disease, defined as absent pedal pulse or signs or symptoms of limb ischemia, including a history of intermittent claudication
- Patients with amyloidosis, thyroid induced heart failure, high output failure secondary to an arterio-venous fistula, and significant uncorrected primary valvular disease (with the exception of mitral regurgitation believed secondary to LV dilatation)
