Ann Thorac Surg:冠状动脉旁路移植手术优于植入药物洗脱支架:男女有别?

2015-08-30 MedSci MedSci原创

一些随机对照试验以及观察性研究已经对比冠状动脉旁路移植手术(CABG)与植入药物洗脱支架(DES)两种治疗方式患者的预后的差异,但是这些研究没有系统的调查不同性别患者预后的相对差异。我们想对比不同性别患者CABG手术和经皮冠脉植入DES两种方式的3年预后(例如死亡率,死亡率/心肌梗死/卒中,以及血管再通)的差异。招募4532女性患者(2266对CABG和DES治疗方式的患者)和11768名男性患者

一些随机对照试验以及观察性研究已经对比冠状动脉旁路移植手术(CABG)与植入药物洗脱支架(DES)两种治疗方式患者的预后的差异,但是这些研究没有系统的调查不同性别患者预后的相对差异。我们想对比不同性别患者CABG手术和经皮冠脉植入DES两种方式的3年预后(例如死亡率,死亡率/心肌梗死/卒中,以及血管再通)的差异。

招募4532女性患者(2266对CABG和DES治疗方式的患者)和11768名男性患者(5884对),根据患者多种危险因素分别配对,并且对比3年预后。

结果:植入DES男性患者和女性患者的死亡率(校正HR分别为1.28,1.22;95%CI, 分别为1.06-1.54,1.06-1.41)都显著升高,心肌梗死/死亡率/卒中发生率升高(校正HR分别为1.40,1.36; 95% CI分别为 1.19-1.64, 1.20-1.54)。在一些预选的患者亚组中发现冠脉搭桥手术的优势。这两种治疗方法,男性患者比女性患者的不利预后低。例如:男性患者CABG和DES两种干预方式的死亡率分别为 8.0% 和9.1%,女性患者的死亡率分别为11.8%和13.7%。

男性患者和女性患者,CABG手术明显优于植入DES。这种优势也存在于有高危或无高危因素的患者。
