Impact of Stenosis and Plaque Features in Coronary CT Angiography, Physiologic Assessment and Pharmacotherapy on the Clinical Outcomes After Invasive Coronary Angiography
The investigators aim to investigate the prognostic implication of stenosis and plaque features on coronary CT angiography (CCTA), physiologic assessment, and pharmacotherapy after invasive coronary angiography.
• Age ≥ 20 years
• Patients who undergo CCTA within 90 days before FFR measurement by clinical needs
• Patients with a vessel determined to defer revascularization after FFR measurement.
• Age ≥ 20 years
• Patients who undergo CCTA within 90 days before FFR measurement by clinical needs
• Patients with a vessel that undergo stent implantation and FFR measurement both before and after revascularization (pre-PCI FFR and post-PCI FFR).
⁃ Patients with multiple vessels that meet inclusion criteria of the deferral of PCI group and PCI group will be assigned to the PCI group.
