Secondary imaging outcome measures:
Correlation among FFR value, plaque burden by IVUS, MLA by IVUS, and LCBI.
Correlation among plaque burden by IVUS, MLA by IVUS, and LCBI by NIRS-IVUS, plaque burden by CT, plaque type by CT, and diameter stenosis by CT.
Correlation among PPG (pullback pressure gradient), plaque burden by IVUS, MLA by IVUS, and LCBI.
Sub-group analysis:
MaxLCBI4mm 400
MaxLCBI4mm median value
Plaque burden >=70%
Minimal lumen area <=4.0 mm2
Hemodialysis
PCI indication (STEMI vs. NSTEMI vs. UAP)
Ischemic risk
Diabetes
Sub categories of FFR value (FFR0.81-0.85, 0.86-0.90, 0.91-1.00)
Diameter stenosis, CT value <30 HU, positive remodeling, spotty calcification, napkin ring sign as assessed by coronary CT
Observational
18 | years-old | <= |
Not applicable |
Male and Female
1. Patients >=18 years of age.
2. Patients with ACS undergoing PCI within 4 weeks before study enrollment.
3. Patients with deferred coronary lesions by FFR (i.e. FFR>0.80) with a moderate stenosis (visual estimation of diameter stenosis >=50%, <90% by coronary angiography) in non-culprit coronary artery.
1. Target vessels* previously treated by PCI.
2. Target vessels* with significant coronary calcification or tortuosity deemed to preclude NIRS-IVUS evaluation.
3. Target vessels* with reference lumen diameter <=2mm.
4. History of CABG.
5. Unstable clinical status (hemodynamic or electrical instability).
6. Patients unwilling or unable to provide informed consent.
7. Life expectancy is less than 1 year at study enrollment.
8. Patients considered unsuitable for the study at the discretion of the operator.
*Target vessel is defined as a non-culprit coronary artery with deferred coronary lesions by FFR (i.e. FFR>0.80) with a moderate stenosis (visual estimation of diameter stenosis >=50%, <90% by coronary angiography).
