Percutaneous intervention for the treatment of multivessel coronary artery disease continues to displace coronary artery bypass graft surgery. But controlled trials of percutaneous intervention versus coronary bypass, in meta-analysis, have shown a significant survival advantage for coronary bypass. Studies of bare metal stents have not presented any data to prompt reversal of this conclusion for all but the small portion of patients most suited for stenting. Drug-eluting stents have no survival advantage compared with bare metal stents. Data from real-world registries have shown that the current therapy of multivessel disease patients has resulted in a relative excess mortality of as much as 46% in patients with initial stenting compared with patients with initial coronary bypass. Ethical considerations demand that patients with multivessel disease be informed of the documented mortality benefit of coronary bypass graft surgery.
经皮介入治疗多支冠状动脉疾病的应用持续增加,逐渐取代了冠状动脉旁路移植术。但在荟萃分析中,经皮介入与冠状动脉旁路移植的对照试验显示,冠状动脉旁路移植术具有显著的生存优势。除了一小部分最适合支架置入的患者外,裸金属支架的研究并未提供任何数据来促使这一结论被推翻。与裸金属支架相比,药物洗脱支架没有生存优势。来自真实世界登记处的数据表明,与初始接受冠状动脉旁路移植术的患者相比,目前对多支血管疾病患者的治疗导致初始接受支架置入的患者相对死亡率高出多达46%。出于伦理考虑,需要告知多支血管疾病患者冠状动脉旁路移植术已被证明的死亡率益处。
