Biochemical Screening for Pulmonary Hypertension in Preterm Infants with Bronchopulmonary Dysplasia
BACKGROUND: Pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD) is associated with increased morbidity and mortality. Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and decreased levels of amino acid precursors of nitric oxide (NO) have been associated with PH, but have not been studied in infants with PH secondary to BPD.OBJECTIVE: The aim of thi
