Background: The purpose of the present study was to compare the 5-year clinical outcomes after implantation of drug-eluting stent (DES) and bare-metal stent (BMS) in Japanese patients with acute myocardial infarction (AMI). Methods and Results: This study was a subgroup analysis of the Nagoya Acute Myocardial Infarction Study (NAMIS). It included 658 AMI patients, of which 280 were treated with a DES and 378 with a BMS. The major adverse cardiac event (MACE)-free rates during the 5-year follow-up period were similar between the 2 groups (95.7% vs. 96.8%, P=0.482). A significant difference was seen, however, in the target lesion revascularization (TLR) rates (7.9% vs. 17.7%, P<0.0001). Interestingly, there was no significant difference between the 2 groups from year 1 to 5 with regard to late TLR (2.5% vs. 2.1%, P=0.906), despite the markedly lower incidence of TLR within the first year in the DES group compared with the BMS group (5.4% vs. 15.6%, P<0.0001). Conclusions: In this long-term follow-up analysis of DES compared to BMS in Japanese patients with AMI, there was no significant difference in the incidence of MACE. Although a lower rate of TLR was observed in DES group within the first year, the superiority of DES in relation to the incidence of TLR disappeared after the first year following primary percutaneous coronary intervention.
