摘　　要：目的探讨药物洗脱支架（DES）治疗前降支开口病变的近、远期临床疗效，并与早期应用切割球囊预扩张后（CBA）置入金属裸支架（BMS）的近、远期临床疗效进行比较。方法自2003年11月至2005年5月采用DES对51例连续前降支开口病变的患者进行介入治疗，选自2000年5月至2003年11月应用CBA＋BMS治疗前降支开口病变的连续50例患者作为对照组，要求所有患者在介入治疗后6—8个月进行冠状动脉造影复查，DES组与CBA＋BMS组患者分别完成了2年和4年的临床随访。结果在DES组中1例于住院期间发生急性心肌梗死，住院期间主要不良心脏事件（MACE）发生率为1．96％（1／51），29例完成了6—8个月的冠状动脉造影复查，再狭窄发生率为10．3％（3／29）。在2年临床随访中1例死亡，靶病变重建4例，MACE发生率为9．8％（5／51）。在CBA＋BMS组中住院期间无心脏事件，28例完成了6—8个月的冠状动脉造影复查，再狭窄发生率为17．9％（5／28）。2年临床随访中1例死亡，行靶病变重建5例，MACE发生率为12％（6／50）。结论在2年的临床随访中，支架内再狭窄、MACE发生率两组比较差异均无统计学意义，研究结果提示无论是采用DES还是CBA＋BMS治疗前降支开口病变均有良好的近、远期疗效。Objective To compare the short and long-term clinical and angiographic outcomes of drug-eluting stents （DES） versus cutting balloon angioplasty followed by bare metal stents （ CBA ＋ BMS） for the treatment of ostial lesions of the left anterior desending coronary artery （LAD）. Methods A total of 51 consecutive patients with LAD ostial lesions were treated by DES and all patients had completed 2-year clinical follow-up, 50 consecutive patients with LAD ostial lesions treated by CBA ＋ BMS and followed up for 2 years prior to the DES era （ May 2000 to November 2003 ） served as control group. Results In DES group, one patient experienced acute myocardial infarction （AMI） during hospitalization, the in-hospital major adverse cardiac event （MACE） was 1.96% （ 1/51 ）, angiography follow-up data at 6-8 months were available in 29 patients and the in-DES restenosis was 10. 3% （3/29）, at 2-year clinical follow-up, 1 patient died, 4 patients received target lesion revascularization. Total MACE rate was 9.8% （5/51）. In CBA ＋ BMS group, there was no in-hospital death and AMI. Angiographic follow-up at 6-8 months was completed in 28 cases and in-stent restenosis rate was 17.9% （5/28）. During 2-year follow-up, there was no death and AMI and 6 patients underwent target lesion revascularization. MACE rate was 12% （6/50） in this group. Conclusion This study showed that both clinical and angiographic outcomes were comparable between DES and CBA ＋ BMS treated patients with LAD ostial lesions during the 2-year follow up period.
