Biomarkers of Pediatric Heart Failure

Overview

Heart failure (HF) is a clinical syndrome where the heart is unable to pump the blood required to meet the metabolic demands of the body. Heart failure in children can result from a variety of structural or functional cardiac disorders with subsequent failure of the ventricles to fill with or eject blood

Cardiac biomarkers are useful as diagnostic and prognostic tools, especially in patients with atypical signs and symptoms. High rate of complication in HF led to the search for suitable cardiac biomarker that diagnose heart failure as early as possible, predict outcome, reflect response to treatment and help in staging of heart failure and determine risk (6) . In pediatrics, biomarkers of heart failure are particularly important for the early identification and risk stratification of patients with systemic diseases and associated risk for early development of heart failure. Good biomarkers have the following characteristics: high sensitivity and specificity, the possibility of simultaneous processing of many samples, short analysis time, low cost, and good clinical applications, thus predicting the risk of heart failure and the associated prognosis as well as the adequacy of monitoring \[7\]. . Neutrophil gelatinase-associated lipocalin (NGAL) is a 25 kDa protein covalently bound to matrix metalloproteinase-9 which was first isolated from neutrophils. It belongs to the lipocalin family, NGAL has been found to be elevated in both plasma and urine in patients with HF.(8) NGAL also acts as a growth and differentiation factor in the renal epithelium \[9\].
