摘要

摘要: 目的:回顾性分析无保护左主干病变患者使用雷帕霉素洗脱支架(DES)的经皮冠状动脉介入治疗(PCI)与冠状动脉旁路移植手术(CABG)治疗的中、远期疗效,并探讨应用SYNTAX SCORE来评估病变风险与临床事件的相关性。方法:本研究回顾性收集了176例无保护左主干病变患者,其中CABG组80例,PCI-DES组96例。收集患者的基本情况、左主干病变特点及SYNTAX评分、CABG和PCI手术情况,随访患者术后3年的主要不良心脑血管事件(MACCE)的发生率。结果:术后3年随访,PCI-DES组与CABG组的MACCE发生率及无MACCE生存率比较差异无统计学意义,但PCI组靶血管再次血运重建率(TVR)明显高于CABG组(P<0.05)。用SYNTAX SCORE把PCI-DES和CABG两组患者分为高积分组(≥ 30.0)和低积分组(<30.0):高积分组,术后3年PCI-DES亚组MACCE事件发生率高于CABG亚组(23.53%:18.05%,P<0.05),无MACCE事件生存率低于CABG亚组(51.47%:70.83%,P<0.05)。低积分组,术后3年MACCE事件发生率CABG亚组高于PCI-DES亚组(12.50%:7.14%,P>0.05),而无MACCE事件生存率低于PCI-DES亚组(75.00%:82.14%,P<0.05)。结论:PCI-DES与CABG治疗无保护左主干病变患者总体疗效相似。用SYNTAX SCORE指导无保护左主干病变血管重建方式的选择有重要价值,但在不同的患者人群中,仍应结合临床特征和冠状动脉病变特点选择恰当的血运重建术。

Abstract: Objective:To evaluate the effect of coronary artery bypass grafting(CABG) and percutaneous coronary intervention(PCI) with drug-eluting stents(DES) for unprotected left main coronary artery disease and investigate the relevance between the risk of lesion and major adverse cardiac and cerebrovascular event(MACCE) by syntax score system. Method:We reviewed outcomes among 176 consecutive patients with unprotected left main coronary artery disease who underwent PCI or CAGB.Eighty patients underwent CABG(CABG group) and ninty-six patients received drug-eluting stents(PCI group).Base features,angiographic characteristics,operation data,SYNTAX SCORE and MACCE rates followed up 3 years after operation were recorded. Result:There were more target vessel revascularization events in the PCI group than in the CABG group,although MACCE and MACCE-free rates were similar at 3 years follow-up.Patients were divided into high-score group(≥30.0) and low-score group(<30.0) by using SYNTAX SCORE system.SYNTAX SCORE>30.0 is the independent risk factor of the outcomes of PCI.In the high-score group,MACCE was higher and MACCE-free rate was lower at 3 years in patients underwent PCI than CABG(23.53% vs 18.05%,P<0.05;51.47% vs 70.83%,P<0.05,respectively).In the low-score group,MACCE was higher in patients underwent CABG than PCI at 3 years(12.50% vs 7.14%,P>0.05),but MACCE-free rate was lower in patients underwent CABG than PCI at 3 years follow-up(75.00% vs 82.14%,P<0.05). Conclusion:PCI with DES is feasible and effective for patients with unprotected left main coronary artery disease.
