摘要

Objective The aim of this study was to evaluate SYNTAX score,role in guiding the choice of optimal revascularization strategies in patients with complex coronary artery disease.Methods 361 consecutive patients with de novo left main or three-vessel coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI) with drug-eluting stent (n =191) or coronary artery bypass grafting (CABG) (n =170) between Jan.2008 and Dec.2008 were prospectively studied.Their angiograms were scored according to the SYNTAX score.The patients were divided into three groups according to the SYNTAX score;the lowest SYNTAX score (SYNTAX score ≤ 22),intermediate SYNTAX score (SYNTAX score of 23 to 32),and the highest SYNTAX score (SYNTAX score ≥ 33).The primary end point of this study were defined as the rate of major adverse cardiac and cerebrovascular events (MACCE) at 2 years.The MACCE-free survival curves were estimated by the Kaplan-Meier method.Propensity score analysis was performed using a stratified Cox regression with treatment strategy (PCI vs CABG) as a fixed dummy covariate.Results The overall SYNTAX score ranged from 5 to 65 with mean ± standard deviation of 29.8 ± 11.7.The rate of MACCE at 2 years in the PCI group was significantly higher than that in CABG group (15.7% vs 10.0%,P =0.038).Patients with the lowest or intermediate scores in two groups had similar rate of 2-year MACCE,whereas among patients with the highest scores,the event rate was significantly increased in the PCI group (28.1% vs 11.1%,P =0.011).Conclusion The overall rate of 2-year MACCE in the PCI group was significantly higher compared with CABG.The rate of 2-year MACCE was similar between the two treatment groups for patients with the lowest or intermediate SYNTAX scores.Among patients with highest SYNTAX scores,those in the PCI group had a significantly higher 2-year MACCE rate than those in the CABG group.%目的 评价SYNTAX积分在指导复杂冠心病患者血运重建治疗策略选择的价值.方法 前瞻性、注册研究2008年1-12月北京安贞医院行经皮冠状动脉介入治疗(PCI)或冠状动脉旁路移植术(CABG)治疗的左主干和(或)三支病变冠心病患者361例,其中PCI患者191例,CABG患者170例.术前根据冠脉造影结果按SYNTAX积分系统进行评分,并依据SYNTAX积分将患者分为3组:低分组(0 ~22)、中分组(23 ~32)和高分组(≥33).主要终点是术后2年主要不良心脑血管事件(MACCE)发生率.用倾向得分法调整组间基线特征的不均衡性;用Kaplan-Meier法进行生存分析,比较PCI和CABG预后.结果 入选患者的SYNTAX积分为5~ 65,平均29.8±11.7.CABG组患者SYNTAX积分高于PCI组(33.2±10.9对26.8±11.5,P<0.001),表明CABG组患者冠脉病变特征较PCI组更复杂.CABG组患者2年MACCE发生率低于PCI组,差异有统计学意义(10.0%对15.7%,P=0.038),主要原因在于CABG组再次血运重建率低于PCI组(4.7%对10.5%,P=0.042).在SYNTAX低分组和中分组患者,PCI与CABG术后的2年MACCE发生率相似,分别为6.2%对9.7%(P=0.57)和11.3%对10.5%(P=0.89);而在高分组,PCI组2年MACCE高于CABG组,差异有统计学意义(28.1%对11.1%,P=0.011).结论 左主干和(或)三支病变患者CABG较PCI术后2年MACCE发生率低,但在SYNTAX低分组和中分组患者,PCI与CABG术后的2年MACCE发生率相似,仅在高分组(≥33)PCI组2年MACCE高于CABG组.
