1) This study compared long-term outcomes of 626 STEMI patients treated with primary PCI who were randomized to drug-eluting stents (DES, n=313) or bare-metal stents (BMS, n=313). 2) At 3 years, the rate of major adverse cardiac events (MACE), including death, MI, and target lesion revascularization (TLR), was significantly lower in the DES group compared to the BMS group (10.5% vs 16.3%, p=0.024). 3) Rates of cardiac death (4.2% vs 6.1%), MI (6.1% vs 8.9%), and TLR (3

Background
Implantation of drug eluting stents (DES) has proven to
be both safe and efficient in most patients with coronary
artery disease. However, long-term data are scarce with
regard to their use in STEMI patients treated with PCI

Conclusions
In the DEDICATION trial implantation of DES
(compared with BMS) in STEMI patients
• reduced the rate of MACE and the need for repeat
revascularization
• was not associated with an increased rate of myocardial
infarction or stent thrombosis
• was associated with an increased risk of cardiac death
