Abstract: Objective To evaluate the application of ZEEK thrombus aspiration catheter in treatment of acute myocardial infarction (AMI) in elderly patients. Methods The 52 patients with ST-elevation myocardial infarction(STEMI)were treated with percutaneous coronary intervention (PCI) plus thrombus aspiration by using ZEEK thrombus aspiration catheter (ZEEK group), and 42 STEMI patients were treated only with PCI (control group). The regression rate of ST segment, left ventricular ejection fraction (LVEF), incidence of no-reflow and mortality were followed up after PCI during hospitalization. Results No-reflow occurred in 5 (11.9%) patients and 1 (1.9 %) patient in the control group and ZEEK group, respectively. And 2 deaths were encountered only in the control group. The differences between the two groups were statistically significant (P＜0.05).Conclusions AMI treatments with PCI and application of ZEEK aspiration thrombus catheter are safe and effective. The two methods could lower thrombosis burden, may improve distal myocardium perfusion and cardiac function after the procedure.
