    The plasma concentration of different lipoproteins were measured in 102 control children, in 42 children with a parent suffering from coronary heart disease (CHD), and in 50 children with a parent with cerebrovascular disease (CVD). Significant differences between controls and children in the other two groups were found for apolipoprotein A I, apolipoprotein B, and high density lipoprotein-cholesterol. Children of parents with CHD differed from controls in total cholesterol and apolipoprotein A II concentrations. A highly significant difference furthermore was found in lipoprotein (a) concentrations from children of parents with CHD in comparison with controls, but not between children of parents with CVD and controls. The difference in lipoprotein (a) concentrations (children of parents with CHD compared with controls) were only noticed in children above the age of 10 years. This could be explained by the observed rise of lipoprotein (a) between age 2 and 13 years, which was much more pronounced in the group with parents who had CHD. Plasma glycosaminoglycan concentrations were also measured in the three groups. They were significantly higher in children of parents with CHD and CVD compared with controls; they also varied with age.
