Brief Summary:

The purpose of this trial is to study the use of nesiritide in thoracic aneurysm repair to prevent acute renal failure.

The study hypothesis: Nesiritide, given prophylactically prior to surgery may prevent acute renal failure requiring dialysis and/or decrease mortality.

Condition or disease Intervention/treatment Phase
Cardiovascular Disease Acute Renal Failure Death Drug: Nesiritide Phase 3

Detailed Description:

Acute renal failure is a major and serious complication of more than 200,000 cardiovascular surgeries performed on adult Americans annually ( The incidence of acute renal failure (ARF) after cardiac surgery (depending on criteria used to define ARF) is 1-5%, in the absence of preexisting renal dysfunction. The subset of patients with thoracic aortic aneurysm surgery have a higher risk for the development of postoperative ARF (25-40% - ARF defined as doubling of serum creatinine; 13% - ARF defined as requirement for dialysis). This risk is further increased by various peri-operative factors, especially cardiopulmonary bypass time.

The overall postoperative mortality rate for cardiovascular surgery is 2.2%, but is much higher for thoracic aortic aneurysm surgery (8-10% for elective repair, 25-50% for ruptured thoracic aorta aneurysm repair). The major risk factor for thoracic aortic aneurysm surgery related mortality is post-operative ARF requiring dialysis. When thoracic aortic aneurysm surgery is complicated by acute renal failure, the mortality rate worsens to 50%. Thus, identifying ways to prevent acute renal failure may have a major impact on the outcome of cardiovascular surgery. A retrospective study of the use of nesiritide in cardiovascular surgery patients by our group has demonstrated a tendency towards a decreased incidence of renal failure and mortality, when the medication is used prophylactically.
