The appilication of diver CE thrombus aspiration catheter in patients during the recovery of acute ;myocardial infarction with percutaneous coronary intervention / 中国介入心脏病学杂志

ABSTRACT

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<0.05). The LVEF after 6 and 12 months were higher in the aspiration group (both P<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.
