Abstract: 【Abstract】 Objective To investigate the safety of Yinyi micropole drug coated stent after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction．Methods From Oct.2008 to Jan．2010,consecutive patients with AMI underwent PCI were divided into Yinyi micropole drug coated stents group(Group A n=100)and PARTNER stents group(Group B n=90)according to the type of the stents．The incidence of major adverse cardiovascular event(MACE) and stent thrombosis were evaluated during in-hospital 、30days and 6 months follow up after PCI．Results One hundred and ninety patients were successfully treated by PCI .NO in-stent thrombosis was diagnosed in the group A ,while one case stent thrombosis in group B（0 versus 1.1%, P>0.05）.The rates of MACE did not differ significantly between the groups with Yinyi micropole drug coated stents and those PARTNER stents during in-hospital 、30days and 6 months follow up after PCI. Conclusion Implantation of Yinyi micropole drug coated stent after PCI is as safe as PARTNER stents in patients with AMI.
