Coronary Artery Disease

Brief summary

To place two different everolimus-eluting stents (EES), a bioabsorbable polymer EES (Synergy®) and a permanent-type polymer EES (Xience®), randomly to the ST-elevation acute myocardial infarction (AMI) and to observe and compare the early and chronic vascular responses using the frequency domain optical coherence tomography (FD-OCT). The primary endpoint is the 2-week strut coverage rate by FD-OCT.
