Coronary artery disease
Conditions
Interventions
Gold Standard:Fractional flow reserve (FFR) in ICA is the gold standard for determining whether there is functional ischemia in the coronary arteries.
Gold standard in this study:Fractional flow reser
Index test:Coronary computed tomography angiography derived fractional flow reserve(CT-FFR)
Virtual coronary stenting
CT-FFR value after virtual stent implantation
