AJC:心肺耐力为CABG后死亡独立标志物

2013-07-19 高晓方 译 AJC

美国一项研究表明,术前心肺耐力为冠脉旁路移植(CABG)后死亡率的附加性独立标志物。论文7月15日在线发表于《美国心脏病学杂志》(Am J Cardiol)。 此项研究从胸外科医师学会数据库中纳入596例接受CABG的患者。对CBAG前90天内的电子病历加以评估。通过实现踏车速度、分级和持续时间计算峰值MET。将患者分别为有氧代谢能力降低组(<5 MET;78

美国一项研究表明,术前心肺耐力为冠脉旁路移植(CABG)后死亡率的附加性独立标志物。论文7月15日在线发表于《美国心脏病学杂志》(Am J Cardiol)。

此项研究从胸外科医师学会数据库中纳入596例接受CABG的患者。对CBAG前90天内的电子病历加以评估。通过实现踏车速度、分级和持续时间计算峰值MET。将患者分别为有氧代谢能力降低组(<5 MET;78例)和实现≥5 MET组(518例)。利用Fisher精确检验对比两组患者的术前有氧代谢能力以及术后短期发病率和死亡率。

结果显示,对潜在混淆因素进行校正之后,心肺耐力和CABG后并发症呈负相关性。具体而言,术前心肺耐力较低(<5 MET)与手术死亡率和CABG后30天死亡率较高相关(P<0.05)。
