目的分析经皮冠状动脉介入术(PCI)药物洗脱支架治疗冠状动脉无保护左主干狭窄的疗效。方法无保护左冠状动脉主干病例45例,26例行药物支架治疗(PCI组),19例行冠状动脉搭桥治疗(CABG)组,比较两组住院期间、术后6个月及12个月心血管事件发生情况。结果 PCI组平均住院(7.1±2.3)d,短于CABG组的(13.1±4.2)d(P<0.01)。住院期间PCI组心血管事件7例,CABG组4例;术后6个月PCI组心血管事件12例,CABG组8例;术后12个月PCI组心血管事件17例,CABG组11例。三个时间段两组差异均无统计学意义(P>0.05)。结论与CABG比较,PCI治疗冠状动脉无保护左主干狭窄具有手术创伤小、术后恢复快和不增加术后心血管事件等优点。
Objective To analyze the effect of percutaneous coronary intervention (PCI) eluting stent in the treatment of unprotected left main coronary artery stenosis. Methods 45 patients with unprotected left main coronary artery disease, 26 patients underwent PCI (PCI group) and 19 patients underwent coronary artery bypass graft (CABG). The duration of hospitalization, 6 months and 12 months after operation Vascular events occur. Results The average length of hospital stay in PCI group was (7.1 ± 2.3) days, shorter than that in CABG group (13.1 ± 4.2 days) (P <0.01). Cardiovascular events in the PCI group were 7 cases and CABG group 4 cases during the hospitalization; cardiovascular events in PCI group 12 cases and CABG group 8 cases 6 months after operation; cardiovascular events in PCI group 17 cases and CABG group 11 cases . There was no significant difference between the two groups in three time periods (P> 0.05). Conclusion Compared with CABG, PCI treatment of unprotected left main coronary artery stenosis has the advantages of small trauma, rapid postoperative recovery and no increase of postoperative cardiovascular events.
