本文对51例老年心肌梗塞患者与268例健康对照人群间的HLA—A、B位点的抗原频率进行了比较研究。结果显示:心肌梗塞患者的HLA—B_(W67)抗原频率显著高于对照组(Pc=0.0014),RR=63.52。这说明HLA—B_(W67)与老年心肌梗塞有关联,免疫遗传因素对心肌梗塞发生起一定作用。
In this paper, 51 cases of elderly patients with myocardial infarction and 268 healthy controls HLA-A, B site antigen frequencies were compared. The results showed that the frequency of HLA-B (W67) antigen in patients with myocardial infarction was significantly higher than that in the control group (Pc = 0.0014), RR = 63.52. This shows that HLA-B_ (W67) associated with senile myocardial infarction, immune genetic factors play a role in myocardial infarction.
