Background: Interest in hormonal response after pediatric cardiac surgery is growing, but many aspects remain unclear. The aim of this study was to test age-related variations and prognostic values of thyroid hormones, and brain natriuretic peptide (BNP) levels before and after surgery. Methods and Results: A total of 162 children undergoing cardiac surgery were divided into 3 age groups (group 1, n=57 neonates; group 2, n=58 infants; group 3,...
