Insights
This study investigated coronary artery disease risk factors in patients and their families. Findings confirm the significant role of genetic predisposition and specific biomarkers like HDL-cholesterol in disease development.
Area of Science:
- Cardiology
- Genetics
- Biochemistry
Background:
- Identifying coronary artery disease (CAD) risk factors is crucial for prevention.
- Individual predisposition is a significant, yet often complex, risk factor for CAD.
- Familial aggregation of CAD suggests a genetic component influencing disease development.
Purpose of the Study:
- To investigate the familiarity of coronary artery disease.
- To analyze the distribution of lipids, lipoproteins, and fibrinogen in relation to CAD.
- To compare these parameters in subjects with and without a family history of CAD.
Main Methods:
- Study included 130 patients with myocardial infarction (Group A), 38 family members (Group B), and 147 controls.
- Analysis focused on lipid profiles, lipoprotein levels (including HDL-cholesterol and apolipoproteins), and fibrinogen.
- Comparative analysis was performed between patient/family groups and control subjects.
Main Results:
- Familiar forms of CAD exhibited similar lipemic and coagulative profiles to occasional forms.
- Groups A and B showed significant variations in HDL-cholesterol, apolipoprotein A1, Apo A1/B ratio, and fibrinogen compared to controls.
- These variations highlight specific biomarkers associated with familial CAD.
Conclusions:
- The study confirms the significant role of specific biomarkers and their genetic distribution in coronary artery disease.
- Familial aggregation of CAD is strongly supported by the observed variations in key biochemical parameters.
- Understanding genetic predisposition is vital for effective CAD prevention strategies.
Abstract:
The identification of risk factors is very important for primary and secondary prevention of coronary artery disease. Among the different risk factors, the individual predisposition plays an important role. We have studied 130 patients with old myocardial infarction (Group A), 38 subjects belonging to the same family (Group B) and 147 control subjects in order to investigate: familiarity of coronary artery disease; distribution of lipids, lipoproteins and fibrinogen; distribution of these parameters in subjects with and without familiarity for coronary artery disease. Familiar forms showed similar lipemic and coagulative profiles as occasional forms. However, groups A and B showed significant variations in HDL-cholesterol, apolipoprotein A1, Apo A1/B ratio and in fibrinogen when compared with control subjects. These results confirm the important role of these factors and their genetical distribution. The importance of familiar distribution is also evident.
