Lipid profile of children with a family history of coronary heart disease or hyperlipidemia: 9-year experience of an outpatient clinic for the prevention of cardiovascular diseases.
The authors evaluated the lipid profile of children with a positive family history of coronary heart disease (CHD), cerebrovascular disease (CVD), or hyperlipidemia and compared them with controls in order to identify risk indicators for atherosclerosis. A group of 315 children (group A) aged more than 2 years old with a positive family history were evaluated for serum concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), apolipoprotein B100 (ApoB100), apolipoprotein A1 (Apo A1), and lipoprotein (a) (Lp[a]). These values were compared with the levels of a control group of 214 children of comparable age (group B). The median age of children in groups A and B was 10.6 (range 2.3-16) and 9.8 (range 3-13.7) years of age, respectively. Among these children, 196 (52%), 47 (12.5%), and 72 (19.1%) had a positive family history of CHD (group A1), cerebrovascular disease (CVD) (group A2), and hypercholesterolemia (group A3), respectively. We identified 8 children with genetically determined dyslipidemia: 2 children with homozygous and 6 with heterozygous familial hypercholesterolemia. Children in group A3 had significantly higher concentrations of TC, TG, LDL-C, and ApoB100 and lower concentrations of Apo A1 compared with controls, while no significant differences were found in concentrations of lipid variables among children of group A1, A2, and A3. Significant differences were also noted in the concentrations of TC, LDL-C, and Lp(a) between children of group A1 and controls. Screening the progeny of young patients with CHD or familial hypercholesterolemia can identify children at excessive risk for future vascular disease.
