OBJECTIVES: To evaluate the influence of volume overload of the left (LV) and right ventricle (RV) and pressure overload of LV and restrictive physiology on levels of N-terminal proatriopeptide (ANPN) and N-terminal pro-brain natriuretic peptide (NT-proBNP).
DESIGN: We studied 41 children with atrial septal defect (ASD), 35 with patent ductus arteriosus (PDA), 27 with coarctation of the aorta (CoA), 25 with restrictive physiology caused by Mulibrey nanism, and 64 control children. We measured serum concentrations of natriuretic peptides and evaluated ventricular size and function with echocardiography.
RESULTS: In patients with ASD, PDA, and Mulibrey nanism, levels of both ANPN and NT-proBNP were higher than in controls but in children with CoA, only ANPN levels were higher. ANPN levels correlated with RV size in ASD and NT-proBNP levels with LV size in PDA. In patients with restriction, NT-proBNP levels correlated negatively with LV size.
CONCLUSIONS: Correlation between echo measurements and levels of natriuretic peptides varied according to loading condition. Measurement of natriuretic peptide levels provides a supplemental method for non-invasive haemodynamic evaluation of children's heart disease.
