Histocompatibility antigens and myocardial infarction.

HLA typing was carried out in 50 Edinburgh men aged 45 years or under who had experienced a myocardial infarction and in 96 healthy 40-year-old men radomly selected from the same community. No significant differences in antigen frequencies were found, and our results therefore fail to support the hypothesis suggesting an association between HLA-B8 and haplotype A1-B8 with ischemic heart disease.
