Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The patients with intermediate lesions after CT angiography and invasive coronary angiography will be screened, and optical coherence tomography, FFR and selective CT angiography will be performed. The coronary images and FFR values will be registered, and the patients will be followed-up up to 2 years to investigate the adverse clinical events.
