In a previous randomized comparison oral colchicine plus bare metal stent (BMS) compared to BMS plus placebo in a diabetic High risk for re-stenosis population, OC demonstrate a significant reduction of angiographic and intravascular ultrasound parameters of in-stent restenosis (ISR) after BMS implantation at one year of follow up (Journal of the American College of Cardiology,2013,61,1678-1685), with a clinical indication of target lesion revascularization in 3.6%. 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 trial, one year TVR in 8.8% with 1st DES design, Rodriguez A et al EuroIntervention 2006,2:53-60 and 4.0% with 2nd generation DES design ERACI IV Cardiac and cardiovascular interventions Journal, 2014 ). Taking in account those numbers 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. Cost included in hospital, procedural and resources fees, follow up cost including re-hospitalization driving by target vessel revascularization (TVR) and both spontaneous and TVR myocardial infarction (MI) and medication cost for each revascularization strategies Safety end point will be incidence of major adverse cardiac events (MACE) defined as the composite of death from any cause, MI (peri-procedural and spontaneous at follow up) and ischemic driving TVR.
The study will be considered complete after all subjects have completed the 12-month Primary safety and efficacy endpoint was incidence of target vessel failure (TVF) plus one year overall cost with both strategies.. Additional end points are clinical endpoints measured in-hospital at at follow up period. cardiac death, cardiac death plus MI. spontaneous MI beyond 30 day to 5 years, and stent thrombosis rate (ST) (definite or probable by Academic Research Consortium definitions).
A sub-study of changes in biological markers of inflammation in patients with acute coronary syndrome (ACS) including MI will be analyzed in both groups. For this reason, a measurement of interleukin 6, metalloproteases, adiponectin and Protein C reactive (PCR) will be performed at the time of enrolment and 4 days and a month after inclusion.

|---|---|
| Experimental: Oral Colchicine +BMS implantation This group will receive after BMS and Colchicine, at the time of PCI, 0,5 mg twice a day during the first three months after stent implantation | Drug: Oral Colchicine +BMS implantation At the moment of BMS implantation intervention will mean that this group will receive colchicine as described. |
| No Intervention: Second generation Drug eluting stent (DES) This group will receive DES at the moment of randomization and will be treated as standard of care.
All second generation DES should be approved by ANMAT for clinical use. |
