以前研究发现某些冠心病患者血清胆红索浓度低。作者以877例无症状的美国空军飞行员(均为男性)为对象。根据冠脉造影所见,最大狭窄<10％为无冠心病,最大狭窄10～49％为轻度冠心病,最大狭窄≥50％为重度冠心病。总胆红素采用重氮苯磺酸试剂(空白对照)进行测定,逐日变异系数为5.6％(*1.03mm01/L)。A组619例冠心病易患 Previous studies found that some patients with coronary heart disease serum bilirubin concentration is low. The authors target 877 asymptomatic USAF pilots (all men). According to coronary angiography seen, the largest stenosis <10% for non-coronary heart disease, the largest narrow 10 to 49% of mild coronary heart disease, the largest stenosis ≥ 50% for severe coronary heart disease. Total bilirubin was measured with diazobenzene sulfonic acid reagent (blank control) with a daily variation coefficient of 5.6% (* 1.03 mm01 / L). A group of 619 cases of coronary heart disease susceptible
