title: [Comparison between bare metal stents and drug eluting stents for the treatment of chronic total occlusion].
abstract: Patients with chronic total occlusions (CTO) are under high risk of restenosis, repeat recanalization procedures and mortality after stent. In our study we evaluated the clinical and angiographic efficacy of bare metal stents (BMS) and drug eluting stents (DES) implantation for chronic total occlusion.107 patients were divided into two groups: who were successfully treated with BMS (n=60) 56,1% and those who had CTO lesions with Cypher implantation(n=47) 43,9%. Six-month angiographic restenosis rates and major adverse cardiac events (MACE) were compared between the groups. At 6-month angiographic follow up, the restenosis rate was significantly higher in the BMS group (21,8% vs. 4,7%; p<0,001), but there was no significant statistic difference in the rate of MACE (11,6% vs.13,3%; p>0,05). Therefore, the implantation of DES in the treatment of CTO lesions showed more favourable results regarding restenosis compared with BMS implantation, but there was not a trend towards lower MACE rates.
