Answer

Human B-type natriuretic peptide (BNP) (nesiritide [Natrecor]) is a new class of drug in the treatment of heart failure. It is produced through recombinant DNA technology and has the same amino acid sequence as naturally occurring human BNP.

Natriuretic peptides have demonstrated effectiveness in correcting hemodynamic derangements in patients with acutely decompensated heart failure via their vasodilatory and diuretic effects. Data suggest that combined blockade of angiotensin-converting enzyme (ACE) and neutral endopeptidase also has hemodynamic and clinical benefits.

In the Vasodilation in the Management of Acute Congestive Heart Failure (VMAC) trial (nesiritide vs nitroglycerin vs placebo plus standard care), human BNP improved hemodynamics and symptomatology more effectively and with fewer adverse effects than intravenous nitroglycerin during 24 hours in patients with acute decompensated chronic heart failure (CHF). [115] In the Prospective Randomized Evaluation of Cardiac Ectopy with Dobutamine or Natrecor Therapy (PRECEDENT) trial, nesiritide was not associated with the increased heart rate or ventricular ectopy that occurred with dobutamine therapy. [116]

In the ASCEND-HF trial (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure Trial), in which nesiritide was compared with placebo in the treatment of acute heart failure, there was no difference in the rate of rehospitalization for heart failure or all-cause death within 30 days. [117]  Although there was no association with worsened renal function, defined as a more than 25% decrease in estimated glomerular filtration rate, increased rates of hypotension were noted. Given these findings, the investigators could not recommend nesiritide for routine use in the broad population of patients with acute heart failure. [117]
