Optical Coherence Tomography
To evaluate the incidence of late incomplete stent apposition (ISA) and un-coverage by optical coherence tomography (OCT) following everolimus-eluting stent (EES) with bioabsorbable polymerversus zotarolimus-eluting stent (ZES) with permanent polymer implantation in patients with AMI at 12 months.

Tidsramme |
|---|---|---|
|
Percent neointima cross-sectional area
Tidsramme: 12month
|
By OCT, percentage neointima cross sectional area can be obtained by dividing the neointimal area by the stent area.(neointima
cross-sectional area in mm²(Quadratmillimeter)/sec)

|
Mean neointima thickness
Tidsramme: 12month
|
By OCT, neointima thickness can be measured as distance from the endoluminal surface of the neointima to the stent strut.(mean
neointima thickness in millimeter)
