title: Efficacy of sirolimus-eluting stents compared with paclitaxel-eluting stents in an unselected population with coronary artery disease: 24-month outcomes of patients in a prospective non-randomized registry in Southern Turkey.
abstract: BACKGROUND
  The efficacy of drug-eluting stents has been shown in randomized trials, but some controversy exists regarding which stent sirolimus-eluting or paclitaxel-eluting is more effective in unselected Turkish patients. Therefore, we investigated the clinical outcomes of patients who were treated with one type of these drug-eluting stents in the real world.
  
  
  METHODS
  We created a registry and prospectively analyzed data on a consecutive series of all patients who presented to our institution with symptomatic coronary artery disease between February 2005 and March 2007 and who were treated with the sirolimus- or the paclitaxel-eluting stent. The follow-up period after stent implantation was approximately 24 months. The primary end point was a major cardiac event, and the secondary end point was stent thrombosis. Informed consent was obtained from all subjects, and the study protocol was approved by the local ethical committee.
  
  
  RESULTS
  In total, 204 patients were treated with either the sirolimus-eluting stent (n = 103) or the paclitaxel-eluting stent (n = 101). The lesions in the 2 arms of the study were treated similarly by conventional technique. At 24-month follow-up, patients who received the paclitaxel-eluting stent showed significantly higher rates of non-Q-wave myocardial infarction (1.9% vs 5.9%; P: .002), target vessel revascularization (1.9% vs 4.9%; P: .002), coronary artery bypass graft surgery (1.9% vs 6.9%; P: .001), and late stent thrombosis (1.9% vs 3.9%, P: .002).
  
  
  CONCLUSIONS
  Patients who received the sirolimus-eluting stent showed better clinical outcomes compared with those who had the paclitaxel-eluting-stent.
