Lipoprotein (a) concentrations as risk indicators for atherosclerosis

Area of Science:

• Pediatrics
• Cardiovascular Science
• Biochemistry

Background:

• Cardiovascular diseases (CVD) and coronary heart disease (CHD) have significant genetic components.
• Early identification of risk factors in children with familial predisposition is crucial for preventative strategies.

Purpose of the Study:

• To investigate plasma lipoprotein concentrations in children with a parental history of CHD or cerebrovascular disease (CVD).
• To identify potential early biomarkers for cardiovascular risk in pediatric populations.

Main Methods:

• Plasma concentrations of apolipoproteins (A I, A II, B), lipoproteins (HDL-cholesterol, lipoprotein (a)), total cholesterol, and glycosaminoglycans were measured.
• A cohort of 102 control children was compared with 42 children of parents with CHD and 50 children of parents with CVD.

Main Results:

• Children with parental CHD or CVD showed significant differences in apolipoprotein A I, apolipoprotein B, and HDL-cholesterol compared to controls.
• Children of parents with CHD exhibited higher total cholesterol and apolipoprotein A II levels.
• Lipoprotein (a) concentrations were significantly higher in children of parents with CHD, particularly those over 10 years old, with a more pronounced age-related increase.
• Plasma glycosaminoglycan levels were elevated in children of parents with CHD and CVD and showed age-dependent variations.

Conclusions:

• Children with a parental history of cardiovascular disease exhibit distinct plasma lipoprotein profiles.
• Elevated lipoprotein (a) in older children with a parental history of CHD may serve as an early indicator of cardiovascular risk.
• Plasma glycosaminoglycans may also reflect increased cardiovascular risk in this pediatric cohort.
