Study Design • Inclusion criteria: STEMI all comers: shock, elderly included • Exclusion criteria: Contraindications to GP IIb/IIIa Tirofiban SHDB Cypher STEMI UFH - ASA Clopidogrel BMS Abciximab standard regimen CCU Cath-Lab ASA = acetylsalicylic acid, BMS = bare metal stent, GP = glycoprotein, STEMI = ST-segment elevation myocardial infarction, UFH = unfractioned heparin. Valgimigli M et al. Cardiovasc Drugs Ther 04; 18: 225-30.

All Cause Mortality at 3 Years 16% 15% BMS = bare metal stent, SES = sirolimus-eluting stent.
Death/MI at 3 Years 23% 20% P=0.57 at log rank test BMS = bare metal stent, SES = sirolimus-eluting stent.
TVR at 3 Years 25% 10% BMS = bare metal stent, SES = sirolimus-eluting stent, TVR = target vessel revascularization
MACE Rate at 3 Years 41% 29% BMS = bare metal stent, CI = confidence interval, SES = sirolimus-eluting stent, TVR = target vessel revascularization.
Stent Thrombosis at 3 Years 6.8% 5.7% BMS = bare metal stent, SES = sirolimus-eluting stent.
Conclusions • At 3 year Follow-up the composite of death MI CVA and BR was lower in tirofiban+SES arm • This difference was driven by an improvement in angiographic outcome leading to lower TVR • There was no difference in terms of death, MI or cumulative probability of stent thrombosis according to ARC classification
