Phase: Phase 4

In a previous randomized comparison oral sirolimus plus bare metal stent compared to bare metal stent implantation alone demonstrated at one year of follow up a significant reduction of angiographic and clinical parameters of restenosis (ANMAT resolution number 3366 from June 2004 and Rodriguez A et al JACC,2006,47,1522-1529). In addition previous reported registries from our group with Drug Eluting Stents showed similar amount of reduction in clinical parameters (not angiographic)of restenosis (ERACI III, Rodriguez A et al EuroIntervention 2006,2: 53-60). Taking in account that 8. 3% of patients treated with oral rapamycin plus Bare Metal Stents(ORAR II Trial JACC 2006)and 8. 8% of patients treated with DES developed clinical restenosis (ERACI III Registry, EuroIntervention 2006) the investigators sought to compare differences in overall cost with both revascularization strategies at 1, 2, 3 and 5 years of follow up assuming that safety and efficacy clinical end points would be similar.
