摘要(Abstract)：

目的探讨经桡动脉应用单根MAC指引导管行急诊冠状动脉造影和介入治疗(PCI)的可行性和安全性。方法前瞻性单中心、随机对照研究,自2011年8月至12月,75例发病12h内的急性ST段抬高心肌梗死(STEMI)、拟行经桡动脉急诊PCI治疗的患者根据随机序号将患者按1:1比例随机分为MAC组和对照组:MAC组(37例)为直接应用MAC指引导管行冠状动脉造影和介入治疗,对照组(38例)为应用造影导管完成冠状动脉造影后再选择指引导管行介入治疗。比较两组患者血管穿刺成功率、导管室准备时间、鞘管置入时间、操作成功率、造影剂用量、操作时间、透视时间和导管室门-球囊(cathlab door to balloon,C2B)时间、穿刺部位并发症以及30天的主要心脏不良事件(死亡、非致死性心肌梗死和靶病变血运重建)发生率。结果 75例患者,其中男性57例,女性18例,年龄(61.5±12.2)岁。两组穿刺置管成功率均为100%,对照组1例患者因右桡尺动脉环而改股动脉路径完成手术。MAC组和对照组相比,两组患者的穿刺置管时间、PCI操作成功率和造影剂用量无明显差异[(1.73±1.08)min比(1.65±0.84)min,t=-0.398,P>0.05;89.2%比89.2%,χ2=0.140,P>0.05;(127±74)ml比(136±33)ml,t=1.159,P>0.05]。操作时间、C2B时间和透视时间MAC组均明显低于对照组[(27.27±6.97)min比(36.33±13.71)min,t=3.582,P<0.001;(15.11±4.77)min比(18.31±3.84)min,t=3.180,P=0.002;(7.61±3.04)min比(11.17±5.99)min,t=3.227,P=0.001]。穿刺部位并发症:局部血肿每组各2例。30天的主要心脏不良事件发生率两组相似(2.7%比2.7%)。结论经桡动脉应用单根MAC指引导管行急诊冠状动脉造影和PCI是安全和可行的,能明显减少操作时间、透视时间和C2B时间。
