[Distribution of HLA antigens in ischemic heart disease patients with stenocardia]
Insights
Certain human leukocyte antigen (HLA) types are more common in men with coronary heart disease (CHD). These findings suggest a potential genetic link to CHD development and severity.
Area of Science:
- Immunogenetics
- Cardiovascular Medicine
- Human Genetics
Background:
- Coronary heart disease (CHD) is a leading cause of mortality worldwide.
- The role of genetic factors, particularly human leukocyte antigen (HLA) system, in CHD susceptibility is under investigation.
Purpose of the Study:
- To investigate the association between specific HLA antigens and the prevalence of coronary heart disease (CHD) and angina pectoris in a male population.
- To explore correlations between HLA antigen carriage and clinical characteristics of CHD.
Main Methods:
- HLA typing (A, B, and C loci) was performed on 162 male patients with CHD and angina pectoris.
- Comparison of HLA antigen frequencies with control population samples.
Main Results:
- Significantly increased incidence of HLA antigens B13, B15, B17, B22, and Cw3 was observed in coronary patients compared to controls.
- Variations in histocompatibility antigen carriage correlated with disease duration, hyperlipoproteinemic type, serum apoprotein levels, CHD severity, and the number of affected coronary arteries.
Conclusions:
- Specific HLA antigens (B13, B15, B17, B22, Cw3) are associated with an increased risk of coronary heart disease in males.
- HLA antigen profiles may be linked to disease progression and clinical manifestations in CHD patients.
Abstract:
HLA antigens were typed by A, B, and C loci in 162 male residents of Moscow with coronary heart disease (CHD) and angina pectoris, aged 27 to 69 years. Coronary patients showed significantly increased incidence of HLA antigens B13, B15, B17, B22 and Cw3, as compared to control population samples. The rates of some histocompatibility antigens carriage were different in different patients, showing a dependence on the duration of disease, the hyperlipoproteinemic type, serum apoprotein level and some clinical characteristics (the severity of CHD, the number of affected coronary arteries).
