Multicenter prospective investigation on efficacy and safety of carperitide as a first-line drug for acute heart failure syndrome with preserved blood pressure: COMPASS: Carperitide Effects Observed Through Monitoring Dyspnea in Acute Decompensated Heart Failure Study.

Background: Recently, vasodilators have been increasingly being recognized as useful for the treatment of acute heart failure syndromes (AHFS). Although carperitide (alpha-human atrial natriuretic peptide) has vasodilatory, diuretic and organ-protective effects, its efficacy and safety for the first-line drug treatment of AHFS have not been reported.

Methods And Results: A prospective observational study was performed in AHFS patients with preserved systolic blood pressure (SBP >or=120 mmHg), pulmonary congestion and dyspnea who were receiving carperitide monotherapy.
