Abstract CONTEXT: Decompensated congestive heart failure (CHF) is the leading hospital discharge diagnosis in patients older than 65 years. OBJECTIVE: To compare the efficacy and safety of intravenous nesiritide, intravenous nitroglycerin, and placebo. DESIGN, SETTING, AND PATIENTS: Randomized, double-blind trial of 489 inpatients with dyspnea at rest from decompensated CHF, including 246 who received pulmonary artery catheterization, that was conducted at 55 community and academic hospitals between October 1999 and July 2000. INTERVENTIONS: Intravenous nesiritide (n = 204), intravenous nitroglycerin (n = 143), or placebo (n = 142) added to standard medications for 3 hours, followed by nesiritide (n = 278) or nitroglycerin (n = 216) added to standard medication for 24 hours. MAIN OUTCOME MEASURES: Change in pulmonary capillary wedge pressure (PCWP) among catheterized patients and patient self-evaluation of dyspnea at 3 hours after initiation of study drug among all patients. Secondary outcomes included comparisons of hemodynamic and clinical effects between nesiritide and nitroglycerin at 24 hours. RESULTS: At 3 hours, the mean (SD) decrease in PCWP from baseline was -5.8 (6.5) mm Hg for nesiritide (vs placebo, P<.001; vs nitroglycerin, P =.03), -3.8 (5.3) mm Hg for nitroglycerin (vs placebo, P =.09), and -2 (4.2) mm Hg for placebo. At 3 hours, nesiritide resulted in improvement in dyspnea compared with placebo (P =.03), but there was no significant difference in dyspnea or global clinical status with nesiritide compared with nitroglycerin. At 24 hours, the reduction in PCWP was greater in the nesiritide group (-8.2 mm Hg) than the nitroglycerin group (-6.3 mm Hg), but patients reported no significant differences in dyspnea and only modest improvement in global clinical status. CONCLUSION: When added to standard care in patients hospitalized with acutely decompensated CHF, nesiritide improves hemodynamic function and some self-reported symptoms more effectively than intravenous nitroglycerin or placebo.
