Role of Early Pulmonary Hypertension as a Risk Factor for Late Pulmonary Hypertension in Extremely Preterm Infants

Abstract

Early PH is common among extremely preterm infants (20%). Five percent of infants had clinically detected late PH. Infants with early PH had echocardiograms performed earlier than infants without the evidence of early PH. Early PH was not associated with the development of clinically detected late PH.
