Abstract

Background: Congenital heart disease (CHD) is a leading cause of morbidity and mortality in children, often accompanied by hematological and biochemical abnormalities. While previous studies have explored these alterations, inconsistencies remain regarding their prevalence and clinical significance across CHD subtypes.
Objectives: To assess the prevalence and clinical significance of hematological and biochemical abnormalities across CHD subtypes
Patients and methods: This case-control study compared 60 CHD patients (15 each with VSD, ASD, TOF, and PDA) with 40 healthy controls. Venous blood samples were analyzed for complete blood count, liver/kidney function, and coagulation profiles. 
Results: CHD patients exhibited significantly lower hemoglobin level with median of (10.45vs. 11 g/dL, p=0.011) and higher ALT levels   with median of (33 vs. 25 IU/L, p<0.001) than controls. Subgroup analysis revealed elevated  median of WBCs in PDA (13.5×10³/mm³ compared to the median of other groups being (10.6×10³/mm³  for VSD,11×10³/mm³  for ASD,10 ×10³/mm³ for TOF and 11×10³/mm³  for control, p<0.001) and increased AST for TOF patients (42 u/l, compared to median of other groups being 32 u/l for PDA,34 u/l for VSD,29 u/l for ASD and 38 u/l for control,  p=0.008). INR variations were most pronounced in TOF with median of 1.1 and 1 for each PDA, VSD and ASD and 1.04 for control p=0.007).
Conclusion: CHD patients demonstrate distinct hematological and biochemical derangements, with subtype-specific patterns suggesting varied pathophysiological mechanisms. These findings underscore the need for tailored monitoring and early intervention to mitigate complications.
