Do b-type natriuretic peptide levels normalise in preterm infants without a patent ductus arteriosus by the fifth postnatal day?
BNP levels were significantly elevated on postnatal day one in preterm infants without a PDA, but then decreased by day five and continued to stay low after that. Gestational age did not have an effect on BNP levels.
The findings of the present randomized trial did not support a beneficial effect of statin therapy (20 mg/day) against AS progression in Iranian patients with mild to moderate disease.
