Peranan N Terminal-proBrain Natriuretic Peptide dalam diagnosis duktus arteriosus persisten hemodinamik signifikan pada bayi prematur.

Background: Persistent ductus arteriosus is one of the most frequently congenital heart disease found in infant mainly in preterm infant. Echocardiography is the gold standard for the diagnosis of hemodinamically significant patent ductus arteriosus (hs-PDA) in preterm neonates. There are few studies demonstrate that the examination of simple blood assay such as N Terminal-proBrain Natriuretic Peptide (NT- proBNP) may be useful in determining the diagnosis and management of hs-PDA. However in Indonesia there are no studies have been done before even though the level of NT-proBNP accuracy in determining hs-PDA is influenced by the assay kit, and the characteristic of the patient (gestational age and chronological age) Objective: To determine the association between NT-proBNP level and the prevalence of hs-PDA. Methods: Across sectional study was conducted at Dr. Cipto Mangunkusumo Hospital from Desember 2015 to February 2016. Forty-nine preterm neonates with gestational age less than 37 weeks and birthweight of less than 2000 gram were performed echocardiography to determine PDA, subsequently these patients were divided into three groups: non PDA, non hs-PDA, and hs-PDA. Further, in the non hs-PDA and hs-PDA groups, blood NT pro-BNP was examined. We then compared the level of NT pro-BNP between these groups. Results: Among 49 neonates, there were 33 patients with PDA, of those 16 patients were hs-PDA. There was an association between the level of NT pro-BNP and hs-PDA (p
