Serotonin concentration in offspring of parents suffering from premature coronary arterial disease
Insights
Children with parents who experienced early heart attacks show higher plasma free serotonin levels. This suggests potential vascular endothelial dysfunction in offspring at risk for premature coronary artery disease.
Area of Science:
- Cardiovascular Science
- Pediatric Cardiology
- Biochemistry
Background:
- Premature coronary artery disease (CAD) in parents poses a significant risk for offspring.
- Early detection of cardiovascular risk factors in children is crucial for preventive strategies.
Purpose of the Study:
- To investigate potential early markers of cardiovascular risk in children with a parental history of premature myocardial infarction.
- To assess plasma free serotonin concentrations as an indicator of endothelial function in this at-risk pediatric population.
Main Methods:
- A case-control study comparing 31 children (ages 3-14) of parents with premature myocardial infarction (MI) against 42 healthy children with no family history of cardiovascular disease.
- Measurement of plasma free serotonin concentrations in all participating children.
Main Results:
- Children with a parental history of premature MI exhibited significantly elevated plasma free serotonin levels compared to the control group.
- This finding suggests a potential link between elevated serotonin and underlying vascular changes in at-risk youth.
Conclusions:
- Elevated plasma free serotonin may serve as a potential biomarker for early vascular endothelial dysfunction in children predisposed to premature coronary artery disease.
- Further research is warranted to elucidate the role of serotonin in pediatric cardiovascular risk assessment and prevention.
Abstract:
Thirty-one 3 to 14 years old offspring of parents who had an acute myocardial infarction before age of 45 and 42 healthy children without any family history of cardiovascular disease were investigated. A significant increase in plasma free serotonin concentration was seen in endangered children. From these results it may be supposed that vascular endothelium is dysfunctional in offspring of parents suffering from premature coronary arterial disease.
