About
To treat patients with acute myocardial infarction, primary percutaneous coronary intervention (PCI) will be performed with the use of an everolimus-eluting cobalt- chromium stent (everolimus-eluting stent: EES, Xience Prime, Xpedition), which is the current standard drug-eluting stent (DES). Vascular responses at the site of stent placement will be evaluated by optical coherence tomography (OCT) at 2 weeks or 3 months and at 12 months after stent placement, along with observation of changes over time in the target vessel. The relationships between OCT findings and the time course of platelet aggregation and between OCT findings and the occurrence of major cardio- cerebrovascular events will also be elucidated.

Inclusion criteria
Development of pathological Q waves in the ECG. Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality.
Identification of an intracoronary thrombus by angiography or autopsy Of the AMI patients who met the above definition, the criterial for inclusion is limited to STEMI patients. STEMI is defined as new ST elevation at the J point in at least 2 contiguous leads of equal or greater than2 mm (0.2 mV) in men equal or greater than1.5 mm (0.15 mV) in women in leads V2-V3 and/or of equal or greater than 1 mm (0.1 mV) in other contiguous chest leads or the limb leads
