title: [Efficacy and safety of implantation of multiple drug-eluting stents].
abstract: OBJECTIVE
  To assess the efficacy and safety of implantation of multiple drug-eluting stents.
  
  
  METHODS
  A retrospective study of 151 cases was conducted, including 34 with implantation of at least 3 drug-eluting stents in the coronary artery (MS group), 53 with implantation of two stents (TS group), and 64 with a single stent (OS group). The incidence of major adverse cardiovascular event (MACE) and restenosis was evaluated.
  
  
  RESULTS
  No significant difference was found between the 3 groups in the incidence of MACE or in the stent thrombosis rate 30 days after the implantation. Follow-up of the patients for 6 months still showed comparable restenosis rate and MACE incidence between the 3 groups.
  
  
  CONCLUSIONS
  Implantation of multiple drug-eluting stents does not increase the risk of restenosis or MACE, and has comparable safety and efficacy with implantation of single and two stents.
