low FFR group (<0.8)
the patient with FFR values less than 0.8
high FFR group (>0.8)
the patient with FFR values greater than 0.8
- Differences VH-IVUS plaque composition between different FFR groups [ Time Frame: baseline ]VH-IVUS tissue composition (necrotic core, dense calicium, fibrotic, fibrofatty %) and atheroma type will be compared according to different FFR groups at the time of measurement procedure.
- Serial physiologic and plaque composition changes of deferred lesions at 1 year FFR and VH-IVUS follow-up. [ Time Frame: one year ]Approximately 60-70 of 100 enrolled patients would be deferred according to FFR values. Patient who provide consent for clinical and angiographic follow-up at one year would be assessed by physiologic FFR and VH-IVUS derived plaque composition. Relationship of serial physiologic and plaque composition changes will be evaluated. Anatomic and physiologic parameters associated with plaque progression and/or regression will be determined.
- Serial physiologic and plaque composition changes of stented lesions at 1 year FFR and VH-IVUS follow-up. [ Time Frame: one year ]Approximately 30-40 of 100 enrolled patients would be stented according to FFR values. Patient who provide consent for clinical and angiographic follow-up at one year would be assessed by physiologic FFR and VH-IVUS derived plaque composition including stented segment. Relationship of serial physiologic and plaque composition changes will be evaluated. Anatomic and physiologic parameters associated with stent failure will be determined.
