Key result
Long-term ANP infusion significantly improved hemodynamics in severe acute heart failure, decreasing mean pulmonary capillary wedge pressure from 23 to 13 mm Hg at 48 hours.

Does long-term atrial natriuretic peptide (ANP) infusion improve hemodynamic parameters and diuresis in patients with severe acute heart failure resistant to various therapies?
Long-term ANP infusion significantly improves hemodynamics and diuresis without tolerance in patients with severe, therapy-resistant acute heart failure.
Kitashiro et al. (1999) conducted an RCT in severe acute heart failure (n=36). Atrial natriuretic peptide (ANP) infusion vs. Normal saline was evaluated on Hemodynamic parameters at 48 hours. Long-term ANP infusion significantly improved hemodynamics in severe acute heart failure, decreasing mean pulmonary capillary wedge pressure from 23 to 13 mm Hg at 48 hours.
