Insights
Lipoprotein(a) [Lp(a)] levels are linked to ischemic heart disease and cardiovascular risk factors in a Brazilian population. This study confirms Lp(a) as a significant factor in heart disease occurrence.
Area of Science:
- Cardiology
- Biochemistry
- Epidemiology
Background:
- Lipoprotein(a) [Lp(a)] is implicated as a cardiovascular disease risk factor.
- Its independent role in cardiovascular disease remains debated in scientific literature.
Purpose of the Study:
- To assess the association between serum Lp(a) levels and ischemic heart disease.
- To investigate the relationship between Lp(a) and other cardiovascular risk factors in a Brazilian cohort.
Main Methods:
- Serum Lp(a) levels were measured in 400 individuals from Ouro Preto, Brazil.
- Analysis included lipid profile, blood glucose, anthropometric, and clinical parameters.
- Multivariate analysis examined interactions between Lp(a), risk factors, and ischemic heart disease.
Main Results:
- Serum Lp(a) levels showed a significant association with ischemic heart disease.
- Lp(a) levels correlated with age, total cholesterol, LDL-cholesterol, and body fat percentage.
- A strong association was observed between Lp(a) and the Framingham risk score (p=0.003).
- Multivariate analysis identified significant interactions involving ischemic heart disease, sex, age, and total cholesterol.
Conclusions:
- Serum Lp(a) levels are correlated with the occurrence of ischemic heart disease.
- Lp(a) is associated with key cardiovascular risk factors, reinforcing its clinical significance.
Abstract:
Evidences suggest that lipoprotein(a) [Lp(a)] is an important risk factor for cardiovascular disease. However, literature has been controversial in confirming its role as an independent risk factor for cardiovascular disease. The objective of the present study is to evaluate the association between serum levels of Lp(a) and ischemic heart disease as well as other cardiovascular risk factors in a population-based study conducted on a local cohort of the Brazilian population. Lp(a) serum levels were measured in 400 individuals selected from a larger sample of a populational survey carried out in Ouro Preto, a city in the southeast of Brazil. Lipid profile, fasting blood glucose, anthropometric and clinical parameters were analyzed. Lp(a) levels were significantly associated with the presence of ischemic heart disease. In relation to other cardiovascular risk factors, it was verified that Lp(a) levels were statistically associated with age, total cholesterol, LDL-cholesterol and percentage of body fat determined by bioelectric impedance. Lp(a) was also highly associated with the Framingham risk score (p=0.003). In a multivariate analysis two significant interactions were revealed; one involving ischemic heart disease, sex and age and other associating ischemic heart disease, age and total cholesterol. In summary, in the present analysis Lp(a) serum levels were correlated with the occurrence of ischemic heart disease and other cardiovascular risk factors.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
