Brain Type Natriuretic Peptide
BRAIN TYPE NATRIURETIC PEPTIDE, also called B-type natriuretic peptide (BNP), has emerged as a valuable diagnostic and prognostic marker in the assessment of heart failure in adults.1–7 Serum BNP levels have also been shown to differentiate pulmonary from cardiac causes of dyspnea and to be useful as a screening tool for ventricular hypertrophy, ventricular diastolic dysfunction, transplant rejection, and risk for sudden death in adult patients with congestive heart failure (CHF).3,7,8 In pediatric patients, BNP levels have been found to increase with a hemodynamically significant ventricular septal defect and to correlate with the volume of the shunt and the left ventricular end diastolic volume.7 Recently, BNP levels have been investigated for use in determining the hemodynamic significance of a patent ductus arteriosus (PDA) in preterm neonates.3,7,9–11 They have also been studied for use in the diagnosis and management of persistent pulmonary hypertension in term and near-term infants.6 This article reviews BNP terminology, structure, physiology, measurement, and potential utility in the NICU.
