ESTIMATION OF SERUM N-TERMINAL BRAIN NATRIURETIC PEPTIDE LEVELS IN PRETERM NEWBORNS WITH PATENT DUCTUS ARTERIOSUS(PDA) – A ONE YEAR HOSPITAL-BASED PROSPECTIVE OBSERVATIONAL STUDY

Abstract

Background: Patent ductus arteriosus (PDA) is a common cardiovascular condition in preterm neonates, often diagnosed using clinical and echocardiographic markers. N-terminal pro-brain natriuretic peptide (NT-proBNP) has been proposed as a potential biomarker for PDA screening and severity assessment.
