Congenital heart disease (CHD) is linked to both clotting and bleeding risks, with past studies showing mixed results on platelet activity in affected infants, prompting this investigation.
The study enrolled 19 infants with CHD and 21 controls, using advanced mass spectrometry to analyze platelet surface markers and cytokine levels in the blood.
Results indicated significant differences in platelet activation in CHD infants, revealing unique subpopulations of platelets, increased hypogranular platelets, and elevated plasma cytokines, suggesting complex platelet behavior in this condition.
