Hyperlipemia among 1407 Danish children whose fathers have died from ischemic heart disease before age 45

Area of Science:

• Cardiology
• Pediatrics
• Genetics

Background:

• Ischemic heart disease (IHD) poses a significant public health challenge.
• A family history of premature IHD is a strong risk factor for cardiovascular disease in offspring.
• Understanding lipid profiles in children with paternal IHD history is vital for early risk assessment.

Purpose of the Study:

• To investigate the prevalence of dyslipidemia in children with fathers who died from premature ischemic heart disease.
• To determine the incidence of familial hypercholesterolemia (FH) in this at-risk pediatric population.
• To establish recommendations for lipid screening in children with a paternal history of early-onset IHD.

Main Methods:

• A cohort of 1407 children with paternal IHD before age 45 was studied.
• Serum lipid levels (cholesterol, triglycerides) were measured at three separate visits.
• Prevalence of hyperlipemia and familial hypercholesterolemia was compared to reference populations.

Main Results:

• At the first visit, 15% of children had hypercholesterolemia and 8% had hypertriglyceridemia.
• These figures decreased to 3% and 1.4% by subsequent visits, but remained approximately 10 times higher than in a reference population.
• Familial hypercholesterolemia (FH) was identified in 1.8% of the children, a 10-15 times higher prevalence than in the general population.

Conclusions:

• Children with a paternal history of premature ischemic heart disease exhibit a significantly elevated risk of hyperlipemia.
• Routine serum lipid measurement is recommended for children from families with a history of early-onset coronary heart disease.
• Early detection and potential treatment of persistent hyperlipemia in these children are warranted to mitigate future cardiovascular risk.
