- Treated with investigational drug or device within last 30 days
- documented fever (>101 degrees F) within 72 hours of surgery
- WBC > 15,000/mm3 within 72 hours of surgery
- Documented bacterial/fungal/viral infection requiring administration of IV antibiotics within 7 days before surgery
- Pulmonary disease (COPD, asthma or other condition) that required inpatient medical or surgical treatment within 60 days before surgery. Treatment exclusion criteria (obtained after anesthesia induction and before chest incision prior to the start of study drug) include: mean pulmonary artery pressure consistently < or equal to 15mmHg
- central venous pressure consistently < 6 mmHg
- and systolic blood pressure consistently < 90 mmHg. Use of open-label nesiritide within 48 hours of study drug administration.

5. Study Description
Brief Summary
The purpose of this study is to assess the effects of nesiritide compared to placebo when given with standard of care therapies, on kidney function, heart function and the need of other treatments in heart failure patients undergoing heart bypass graft surgery that requires the use of a cardiopulmonary bypass machine (CPB pump or heart-lung machine).
Detailed Description
In coronary heart disease (CHD), the coronary arteries become clogged with calcium and fatty deposits. The deposits, called plaques, narrow the arteries that carry blood to the heart muscle and could cause ischemic heart disease (too little blood and oxygen reaching the heart muscle). Coronary Artery Bypass Graft (CABG) surgery is a treatment option for ischemic heart disease. CABG surgery is surgery to create new routes for blood to flow around narrowed and blocked arteries so that the heart muscle will receive needed oxygen and nutrients. Acute kidney injury is a serious risk of CABG surgery while on CPB pump (heart-lung machine), which could result from ischemia during and following surgery. This study is a double-blind (neither the patient nor the doctor knows whether the patient is assigned to receive study drug or placebo), randomized (assigned to treatment by chance), placebo-controlled (study drug results compared to placebo results) study to determine the effectiveness of nesiritide compared to placebo when given to HF patients undergoing CABG surgery requiring the use of a CPB pump . Patients will be enrolled into the study until 250 patients have received study drug or placebo. Patients will be randomized to one of two treatment groups in a 1:1 ratio (nesiritide plus standard care: placebo plus standard care) within each site. Study medication administration will be initiated after measurement of qualifying baseline hemodynamics and prior to chest incision. Nesiritide or placebo will be administered as a continuous IV infusion at a rate of 0.01 mcg/kg/min for a minimum of 24 hours and a maximum of 96 hours. Patients will be followed through 30 days from start of study drug. All patients may receive additional standard care medications including inotropes, pressors, vasopressin, antiarrhythmics, diuretics, nitrates, and nitric oxide as needed. Patient safety will be monitored throughout the study through physical exams, vital signs (heart rate, blood pressure, respiratory rate, and temperature), blood tests, and side effects. A follow-up communication 180 days after the start of study drug was implemented to collect mortality data. The patients assigned to the nesiritide group will receive a continuous I.V. infusion at 0.010 mcg/kg/min of nesiritide for at least 24 hours and could be extended to up to 96 hours. The patients assigned to the placebo group will receive matching placebo.
