[The Fuenlabrada study: a familial aggregation of ischemic cardiopathy and cardiovascular risk factors]
Insights
Paternal history of early coronary heart disease (CHD) significantly increases CHD risk in offspring. This familial aggregation is linked to inherited coronary risk factors (CRF), though not all cases are explained.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Public Health
Context:
- Familial aggregation of coronary heart disease (CHD) and coronary risk factors (CRF) is a significant concern in cardiovascular health.
- Understanding the genetic and environmental influences on CHD is crucial for effective prevention strategies.
Purpose:
- To evaluate the familial aggregation of coronary heart disease (CHD) and coronary risk factors (CRF) in adult relatives of children.
- To compare CHD and CRF prevalence between children with and without a parental history of early CHD.
Summary:
- The study analyzed 2,153 children without parental CHD history (Group I) and 266 children from families with parental early CHD (Group II).
- Familial CHD aggregation was 9.7 times more frequent in paternal families of Group II compared to Group I.
- Fathers in Group II exhibited higher rates of hyperlipidemia, hypertension, smoking, diabetes, and obesity. Children in Group II had elevated LDL and decreased HDL cholesterol levels.
- While CRF prevalence was higher in Group II children, 33% showed no detectable CRF.
Impact:
- Identifies a strong paternal link in familial CHD aggregation, suggesting a significant genetic component.
- Highlights the role of known coronary risk factors in explaining familial CHD, but also indicates other contributing factors may exist.
- Informs targeted screening and early intervention strategies for families with a history of premature coronary heart disease.
Unlabelled:
Familial aggregation of coronary heart disease (CHD) and coronary risk factors (CRF) were evaluated by clinical history in adult relatives of children surveyed for CRF. Population was divided into two groups: Group I included 2,153 children without parental history of CHD. Group II included 266 children of 112 families with parental history of early CHD (before 56 years). In 105 cases the patients were the fathers and in 7 cases the mothers. All the patients were admitted to a coronary care unit. Familial aggregation of CHD was 9.7 times more frequent in paternal families of group II (p less than or equal to 0.0001) than in group I; there was no differences in maternal families. Higher prevalence of hyperlipidaemia, blood pressure hypertension, smoking habits, diabetes and obesity in fathers of group II was observed. Children in group II showed increased levels of C-LDL and decreased levels of C-HDL compared with those of group I. The prevalence of CRF was also significantly higher in children of group II, although in the 33% of the children of group II no CRF was detected.
Conclusion:
a substantial proportion, but not all cases, of familial aggregation of CHD could be explained by known CRF.
