The platelets in cyanotic congenital heart disease

The mean platelet count in 102 children with congenital cyanotic heart disease was found to be 235,000/mm3 ± 1 S.D. of 85,000/mm3 as compared to 260,000 ± 70,000 in an age-matched group of normal children. In the cyanotic children, whose mean oxygen saturation was >80%, the mean platelet level was 315,000/mm3 as compared to 185,000/mm3 in the 80% oxygen saturation group was 13.2 gm/100 ml as compared to 17.2 in the
