　　目的：研究无保护左主干冠状动脉(ULMCA)病变高龄(≥75岁)患者行经皮冠状动脉介入治疗(PCI)的临床疗效。方法：对我院行PCI的ULMCA病变的高龄患者共85例,与同期行PCI的非高龄(<75岁)ULMCA病变患者进行比较其主要不良心脏事件(MACE)的差异。结果：平均随访(16±5)月,两组临床基线资料上,高龄组与非高龄组比较,高血压、陈旧心肌梗死、陈旧脑梗死、慢性肾衰竭比例更高(P均<0.05),左室射血分数更低(P<0.05),EuroSCORE积分和SYNTAX积分更高(P<0.05),但糖尿病比例更低(P<0.05),所有患者均成功完成PCI,高龄组单支架术应用更多(P<0.05),随访研究结果示,高龄组的MACE事件有升高趋势,但差异未达到统计学意义(P>0.05)。结论：ULMCA病变的高龄患者行PCI的短、中期临床疗效差异无统计学意义,结果可以接受。

Objective:To evaluate clinical efficacy of percutaneous coronary intervention(PCI) for high elderly unprotected left main coronary artery lesion (ULMCA) Patients.Methods:85 successive ULMCA lesion elderly(≥75years) patients received PCI,main adverse cardiac events (MACE),are compared with ULMCA lesion patients lower 75 years old who also received PCI at the same period.Results:Compared with none elderly group,elderly group had higher ratio of hypertension,old myocardial infarction,old cerebral infarction,chronic renal failure(P<0.05),lower left ventricular ejection fraction(P<0.05),and higher scores of SYNTAX and EuroSCORE(P<0.05),but lower diabetes mellitus ratio(P<0.05).All patients received a successful PCI,but elderly group has a higher ratio of single stent strategy(P<0.05),and higher MACE ratio but not reaching statistical significance(P>0.05).Conclusion:Compared with none elder ULMCA lesion patients received PCI,high elderly ULMCA lesion patients received PCI has similar desirable results.
