Brief Summary
|
This is a prospective, single center,
single-arm, investigator-initiated study to evaluate neointimal coverage and
vessel wall response after implantation of Supralimus
Grace sirolimus-eluting stent in ST-elevation Myocardial Infarction patients by optical coherence tomography (OCT) analysis. All patients will be
evaluated by OCT analysis at 3 months after the index
procedure.
OCT is a new light-based intracoronary imaging modality with unprecedented spatial resolution. Currently, its axial resolution is only 15 μm, that is, 10 times higher than that of more classical techniques such as intravascular ultrasound (IVUS) based on ultrasounds (150 μm). OCT therefore provides extremely high-quality images of the coronary wall, especially of the structures closest to the vessel lumen. OCT is emerging as a new gold standard for endovascular imaging of stents, atherosclerosis progression, vulnerable plaque, and neointimal proliferation. |
