[Lipoprotein(a) and other lipid parameters in cord blood: a study of 528 cases]
1Hospital General Yagüe, Burgos, Espagne.
Insights
Lipoprotein (a) levels in newborn cord blood may indicate future cardiovascular disease risk. Higher levels in infants with a family history of heart disease suggest lipoprotein (a) is a significant risk factor.
Area of Science:
- Biochemistry
- Pediatrics
- Cardiovascular Medicine
Context:
- Cord blood lipid profiles offer early insights into neonatal health.
- Understanding neonatal lipid parameters is crucial for predicting long-term health outcomes.
- This study examines key lipid and apolipoprotein concentrations in a specific neonatal cohort.
Purpose:
- To analyze concentrations of cholesterol, triglycerides, HDL cholesterol, apolipoproteins A-I and B, and lipoprotein (a) in cord blood.
- To compare these neonatal lipid values with existing population data.
- To investigate the association between familial history of cardiovascular heart disease and neonatal lipoprotein (a) levels.
Summary:
- Cholesterol and triglyceride levels in the studied cord blood were slightly lower than in other populations.
- Lipoprotein (a) concentrations showed a distribution skewed towards lower values, consistent with Caucasian populations.
- Infants with a positive family history of cardiovascular heart disease exhibited higher mean lipoprotein (a) levels and a greater prevalence of elevated values (>5 mg/dl).
Impact:
- The findings highlight lipoprotein (a) as a potential early indicator and significant risk factor for cardiovascular heart disease.
- This research underscores the importance of neonatal screening for lipid profiles, particularly lipoprotein (a).
- Results contribute to understanding the genetic and familial influences on cardiovascular risk from birth.
Abstract:
We have studied the concentrations of cholesterol, triglycerides, high-density lipoprotein cholesterol, apolipoproteins A-I and B, and lipoprotein (a) in cord blood, from children born in our hospital for a five-month period. Cholesterol and triglycerides values were slightly lower than values obtained in cord blood within other populations. The distribution of lipoprotein (a) concentrations was markedly skewed towards low values (mean = 1.74 mg/dl, median = 1 mg/dl), similar to that of other young or adult Caucasian populations. Children with a positive familial history of cardiovascular heart disease had a higher mean lipoprotein level (a), and a higher prevalence of lipoprotein values exceeding 5 mg/dl, than children with a negative familial history. These results suggest that lipoprotein (a) is an important risk factor for cardiovascular heart disease.
