INTRODUCTION: Heart failure (HF) is characterized by neuroendocrine activation. The cardiac natriuretic hormones, including atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), together with their related pro-peptides (proANP and proBNP) represent a group of peptide hormones produced by the heart. A normal NT-proBNP level has a high negative predictive value for heart failure. The use of NT-proBNP testing is helpful in diagnosing acute HF in the emergency care setting, allowing an early and optimal treatment. The purpose of this study is to assess the prognostic value of NT-proBNP in heart failure in children younger than 3 years old and to establish whether it correlates with the NYHA/Ross functional class and left ventricle systolic function.
METHODS: We enrolled 24 consecutive children with HF due to congenital heart diseases and dilated cardiomyopathy. The serum levels of NT-proBNP were measured, all patients underwent echocardiography and left ventricle ejection fraction was calculated.
RESULTS: The highest median value of NT-proBNP was recorded in patients with cyanotic heart diseases (248.0 fmol/mL), p = 0.610. NT-proBNP had a negative correlation with the ejection fraction of the left ventricle: Spearman's rank correlation coefficient was -0.165.
CONCLUSIONS: NT-proBNP levels correlate with the severity of HF in infants and small children younger than 3 years old with heart failure due to congenital heart diseases and dilated cardiomyopathy.
