Diver CE血栓抽吸导管在急性心肌梗死恢复期患者介入术中的应用

The appilication of diver CE thrombus aspiration catheter in patients during the recovery of acute myocardial infarction with percutaneous coronary intervention

目的评价Diver CE血栓抽吸导管在急性心肌梗死(AMI)恢复期介入过程中的效果。方法选择2010年1月至2011年12月间AMI恢复期血栓负荷较重患者共50例,随机分为两组,应用Diver CE血栓抽吸导管的血栓抽吸组和不应用Diver CE血栓抽吸导管的常规经皮冠状动脉介入治疗(PCI)组。比较两组患者基础资料、PCI相关情况及临床预后等。结果两组患者基础临床资料差异无统计学意义(P>0.05);术后血栓抽吸组血栓积分(TS)、心肌呈色分级(MBG)3级获得率、无复流及慢血流发生率低于常规对照组(P<0.05);血栓抽吸组术后6个月、12个月左心室射血分数(LVEF)均高于常规对照组(P<0.05);住院期间和术后随访期间主要不良心血管事件(MACE)发生率两组比较差异无统计学意义。结论在对血栓负荷较重的AMI恢复期患者行PCI的过程中,应用Diver CE血栓抽吸导管是安全、有效的一种方法。

Objective To evaluate the effect of Diver CE aspiration thrombus catheter used in patients during the recovery of acute myocardial infarction （AMI） with percutaneous coronary intervention （PCI）. Methods A total of 50 AMI patients were enrolled from January 2010 to December 2011. Twenty-ifve patients received PCI and used the Diver CE aspiration thrombus catheter （aspiration group）;and the other 25 patients received routine PCI （routine PCI group）. The basic characteristics, PCI characteristics, myocardial perfusion indexes and clinical data were compared and analyzed. Results There was no statistically difference between two groups in basic characteristics. Compared with the routine PCI group, higher rate of myocardial blush grade 3 but lower thrombus scores were found in the aspiration group. The incidence of no-lfow or slow-lfow were also lower in aspiration group （all P＆lt;0.05）. The LVEF after 6 and 12 months were higher in the aspiration group （both P＆lt;0.05）, no difference in MACE between the two groups. Conclusions Using the Diver CE thrombus aspiration in PCI is a simple and safe by method for treatment of acute myocardial infarction with high thrombosis burden. It can improve reperfusion decrease the rates of no-relfow on slow-relfow and can improve the long-term left ventricular function.
