ObjectiveTo study whether antenatal or neonatal glucocorticoid therapy to reduce the incidence and severity of chronic lung disease in preterm infants is associated with long-term adverse cardiac effects and hypertension.DesignRetrospective matched-cohort study.SettingOutpatient clinic of a tertiary care hospital.ParticipantsOne hundred ninety-three children aged 7 to 10 years who had been born prematurely between December 2, 1993, and September 15, 1997. Main Exposure Neonatal treatment with dexamethasone disodium phosphate(n = 48) or the clinically equally effective glucocorticoid hydrocortisone (n = 51), or only antenatal treatment with betamethasone disodium phosphate and betamethasone acetate (n = 51). These 3 groups were compared with a reference group of prematurely born children who had not been exposed to perinatal glucocorticoid therapy (n = 43).Main Outcome MeasuresGeneral hemodynamic data (heart rate and blood pressure), cardiovascular function as assessed at echocardiography, intima-media thickness of the carotid arteries, and cardiac biochemical features as early markers of expansion and volume overload of the cardiac left ventricle (B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide).ResultsNo significant group differences were found for heart rate, blood pressure, biochemical features, intima-media thickness, or systolic or diastolic left ventricular function.ConclusionsAlthough no differences were found in blood pressure and cardiovascular function at school age in children antenatally or neonatally treated with glucocorticoids, further cardiovascular follow-up may be advisable because cardiovascular dysfunction may become apparent only later in life.
