Role of NT-proBNP in the prediction of moderate to severe Bronchopulmonary Dysplasia in preterm infants.

Objective: The objective of the study was to determine the clinical utility of brain natriuretic peptide (NT-proBNP) for prediction of moderate to severe bronchopulmonary dysplasia (BPD). We hypothesized that elevated NT-proBNP levels at 4 weeks of postnatal age may predict the severity of BPD in preterm infants.

Study Design: The study design was a prospective observational study.
