Of these, 202 were treated with SES and the others with EES. The data were collected by a questionnaire through which the annual incidence of coronary stent complications including the occurrence of stent thrombosis (confirmed by re-angiography), the occurrence of acute coronary syndrome leading to hospitalization, the occurrence of vascular myocardial infarction related to the stenting vessel, the need for re-angiography and angioplasty and finally the incidence of cardiac mortality were evaluated.<span style="font-size:10.0pt"></span></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results:</span></i></b> This study showed that the odds ratio of EES thrombosis to SES stent in the unadjusted model is 1.01 (0.06-16.34) and in the adjusted model for confounding variables was equal to 0.80 (0.04-13.35) which in both models, these values were not statistically significant.<span style="font-size:10.0pt"></span></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> The findings of the present study indicate that there is no statistically significant difference between the outcomes in the two groups treated with SES and EES release stents.<span style="font-size:10.0pt"></span></span></span></span> everolimus-eluting stents, sirolimus-eluting stents, percutaneous coronary intervention 507 512 http://caspjim.com/browse.php?a_code=A-10-316-2&slc_lang=en&sid=1 Iraj Jafaripour iraj595@yahoo.com 100319475328460043039 100319475328460043039 No Department of Cardiology, Babol University of Medical Sciences, Babol, Iran Mir Saeid Ramezani mirsaeid2001@yahoo.com 100319475328460043040 100319475328460043040 No Department of Emergency Medicine, Facu Babol University of Medical sciences, Babol, Iran Kamyar Amin Kamyaramin@gmail.com 100319475328460043041 100319475328460043041 Yes Department of Cardiology, Babol University of Medical Sciences, Babol, Iran Naghmeh Ziaie Amiri ziaiexn@yahoo.com 100319475328460043042 100319475328460043042 No Department of Cardiology, Babol University of Medical Sciences, Babol, Iran Mohammad Taaghi Hedayati Godarzi dr.mt.hedayati@gmail.com 100319475328460043043 100319475328460043043 No Department of Cardiology, Babol University of Medical Sciences, Babol, Iran Fahimeh Elhaminejad mirsaeid2001@yahoo.com 100319475328460043044 100319475328460043044 No Babol University of Medical Sciences, Babol, Iran Hemmat Gholinia Ahangar 100319475328460043045 100319475328460043045 No Health Research Institute, Babol University of Medical Sciences, Babol, Iran
