对51例冠心病患者测定β_2—微球蛋白(β_2—MG),并与34例健康者对照。结果显示:冠心病组血β_2—MG明显高于对照组,其中心肌梗塞组血β_2—MG明显高于心绞痛组,提示测定血β_2—MG有助于判断冠心病的严重程度。
51 patients with coronary heart disease were measured β_2-microglobulin (β_2-MG), and 34 healthy controls. The results showed that β_2-MG in coronary heart disease group was significantly higher than that in control group. The β_2-MG level in myocardial infarction group was significantly higher than that in angina pectoris group, suggesting that the determination of serum β_2-MG may help to determine the severity of coronary heart disease.
