Cholesterol among children of men with myocardial infarction
Insights
Children of men with early heart attacks have higher cholesterol levels. This finding suggests elevated childhood cholesterol may predict future coronary heart disease risk in families.
Area of Science:
- Cardiovascular Science
- Pediatric Health
- Genetics and Family History
Background:
- Premature myocardial infarction (heart attack) in fathers is a known risk factor for coronary heart disease.
- Family history is a significant, yet not fully understood, predictor of cardiovascular disease.
- Childhood lipid profiles may offer insights into long-term cardiovascular risk.
Purpose of the Study:
- To investigate the association between paternal history of premature myocardial infarction and plasma cholesterol levels in their children.
- To determine if elevated childhood cholesterol is present across various age groups in offspring of affected fathers.
- To explore the potential of childhood cholesterol as a predictive marker for familial coronary heart disease risk.
Main Methods:
- Cross-sectional study comparing plasma cholesterol levels.
- Inclusion of children from fathers with premature myocardial infarction and control fathers without premature heart disease.
- Analysis of cholesterol levels across nine age groups (1-21 years) and categorization of levels above 230 mg/100 ml.
Main Results:
- Children of men with premature myocardial infarction exhibited significantly higher mean cholesterol levels (195.1 mg/100 ml) compared to children of healthy men (176.6 mg/100 ml).
- Elevated mean cholesterol levels were observed in all nine age strata (1-21 years) among children of affected fathers.
- A 3.6-fold higher prevalence of cholesterol levels exceeding 230 mg/100 ml was noted in children of fathers with premature heart attacks.
Conclusions:
- Elevated plasma cholesterol levels in childhood are associated with paternal history of premature myocardial infarction.
- These findings support the hypothesis that high childhood cholesterol is a potential mechanism linking family history to coronary disease prediction.
- Childhood cholesterol screening may aid in identifying individuals at higher familial risk for cardiovascular disease.
Abstract:
Plasma cholesterol levels were obtained on 90 children of 39 men with premature myocardial infarction and 86 children of 39 healthy men. The mean cholesterol among children of affected men (195.1 mg/100 ml) was higher than among children of healthy men (176.6 mg/100 ml) (P equal to .009). Higher mean levels were demonstrable at each of nine age groups from 1 to 21 years(P equal to .004). Levels greater than 230 mg/100 ml were found in 16.7% of children of affected fathers and 4.7% of children of healthy fathers, a ratio of 3.6 to 1 (P equal to .01). These findings are compatible with the hypothesis that elevated childhood cholesterol level offers a mechanism whereby family history predicts coronary disease. A dip in cholesterol during adolescence, a finding that varies with population studied, was demonstratable among children of both affected healthy men.
