Characteristics and outcomes of patients hospitalized for heart failure in the United States: rationale, design, and preliminary observations from the first 100,000 cases in the Acute Decompensated Heart Failure National Registry (ADHERE).

Background: The ADHERE is designed to study characteristics, management, and outcomes in a broad sample of patients hospitalized with acute decompensated heart failure. Heart failure is a leading cause of hospitalization for adults older than 65 years in the United States. Most available data on these patients are limited by patient selection criteria and study design of clinical trials and single-center studies.

Safety and feasibility of using serial infusions of nesiritide for heart failure in an outpatient setting (from the FUSION I trial).

The Follow-Up Serial Infusions of Nesiritide pilot study was designed to assess the safety and tolerability of outpatient serial infusions of nesiritide in 210 patients with decompensated heart failure who were randomly assigned to usual care only or usual care plus weekly infusions of nesiritide at dosages of 0.005 or 0.01 microg/kg/min for 12 weeks.

Subcutaneous administration of the cardiac hormone BNP in symptomatic human heart failure.

Background: Brain natriuretic peptide (BNP) is a cardiac hormone with vasodilating, natriuretic, renin-angiotensin-aldosterone-inhibiting and lusitropic properties. We have demonstrated that acute subcutaneous (SQ) administration of BNP in experimental congestive heart failure results in elevation of plasma BNP and its second messenger 3',5'-cyclic guanosine monophosphate (cGMP) with natriuresis and reduction in cardiac filling pressures. Furthermore, chronic subcutaneous BNP in experimental congestive heart failure also resulted in increases in cardiac output and decreases in pulmonary capillary wedge pressure and systemic vascular resistance.

Effect of nesiritide (B-type natriuretic peptide) and dobutamine on ventricular arrhythmias in the treatment of patients with acutely decompensated congestive heart failure: the PRECEDENT study.

Background: Dobutamine is commonly used as a means of treating decompensated congestive heart failure (CHF). Although typically effective at improving short-term hemodynamics and symptomatology, the frequent occurrence of arrhythmias and tachycardia is undesirable. In this randomized, multicenter trial, we compared the safety and clinical effectiveness of the cardiac hormone nesiritide (human B-type natriuretic peptide) with dobutamine in hospitalized patients with decompensated CHF.

Effect of nesiritide versus dobutamine on short-term outcomes in the treatment of patients with acutely decompensated heart failure.

Objectives: This study was designed to determine whether nesiritide, administered for acute decompensated congestive heart failure (CHF), affects healthcare costs by hospital length of stay (LOS), readmissions and short-term mortality, compared to dobutamine.

Background: Dobutamine is a commonly used inotropic treatment for CHF. Although dobutamine may have favorable hemodynamic and symptomatic effects, its use may be associated with side effects such as tachycardia, cardiac arrhythmias and myocardial ischemia.
