There is a tendency to equate left main (LM) and left main equivalent (LME) coronary artery disease in terms of the surgical risk and benefit. Eighty-seven patients with LM disease were compared to 78 patients with LME disease as to operative mortality rate and long-term benefits. One hundred percent follow-up was obtained. Although the two groups were similar preoperatively with regard to age, sex, and ventricular function, the operative results in the two groups differed. There was a significantly higher operative mortality rate in the LM group of patients (12.6% versus 2.5%). However, the incidence of graft patency and relief of symptoms was lower in the LME group of patients. The late mortality rate was 4% in both groups. LME disease appears to represent a subgroup of patients with three-vessel disease and cannot be equated with LM disease.
在手术风险和获益方面，人们倾向于将左主干（LM）和左主干等同病变（LME）的冠状动脉疾病视为等同。将87例左主干病变患者与78例左主干等同病变患者在手术死亡率和长期获益方面进行了比较。获得了100%的随访结果。尽管两组患者术前在年龄、性别和心室功能方面相似，但两组的手术结果有所不同。左主干病变组患者的手术死亡率显著更高（12.6%对2.5%）。然而，左主干等同病变组患者的移植血管通畅率和症状缓解率较低。两组的晚期死亡率均为4%。左主干等同病变似乎代表了三支血管病变患者的一个亚组，不能与左主干病变等同。
