Atrial natriuretic peptide and nitric oxide in children with pulmonary hypertension after surgical repair of congenital heart disease.
ANP causes pulmonary vasodilation in some children with pulmonary hypertension secondary to congenital heart disease. In a small group of patients, ANP lowered mean pulmonary artery pressure and pulmonary vascular resistance index > 20% without changing systemic vascular resistance index. Inhaled NO is an effective pulmonary vasodilator and is a more selective pulmonary vasodilator than ANP. The utility of ANP may be limited by its nonselective effects as more selective vasodilator agents are available.
