Acute myocardial infarction (AMI) is the leading cause of mortality in the world. Early invasive strategy with percutaneous coronary intervention (PCI) has been demonstrated to be the most effective strategy to treat AMI. Although drug-eluting stent (DES) has not shown benefits to reduce mortality rate among AMI patients compared with bare-metal stent (BMS), the use of DES in real-world is increasing because of reduced restenosis rates. AMI patients are at higher risk to develop atrial fibrillation (AF) than general population. However, whether early PCI with DES implantation is related to a reduced risk of AF still remains unclear. The purpose of this study is to investigate the association of DES implantation and the risk of AF among patients with AMI treated by early PCI.
The benefit of a drug-eluting stent (DES) in patients with acute myocardial infarction (AMI) is controversial. This study will aim to observe the effect of a DES on the risk of new-onset AF in patients with AMI.
