Biochemical Screening for Pulmonary Hypertension in Preterm Infants with Bronchopulmonary Dysplasia

Abstract

NT-proBNP and the NO precursor citrulline may be cost-effective biochemical markers for screening for the presence of PH in preterm infants who have BPD. If validated in a larger study, such biochemical markers may, in part, replace PH screening echocardiograms in these patients.
