Summary

Conflicting results of an association between the human platelet antigen 1b (HPA-1b or PlA2) allele and the risk of myocardial infarction and coronary artery disease have been reported. To assess the reason for this discrepancy, we determined the HPA-1 genotype in 298 men who had undergone coronary angiography, including 124 individuals with myocardial infarction, 83 individuals with coronary artery disease but no history of myocardial infarction, and 91 control patients. Among patients with acute or recent onset myocardial infarction (<1 year), the prevalence of HPA-1b was higher than among patients with coronary artery disease but without myocardial infarction (33 percent vs. 14 percent, p = 0.016). In patients under 60 years of age this difference was even more pronounced (45 percent vs. 15 percent, p = 0.003). Unlike conventional risk factors HPA-1b does not represent a risk factor for coronary artery disease itself but appears to be associated with increased platelet thrombogenicity.
