Gold Standard:FFR is the "gold standard" for functional index interpretation (when the measured FFR value is =0.75 and =0.85, the preset limit for pressure shift is 0.02. When the measured FFR value i

Inclusion criteria
Inclusion criteria: 1. The degree of stenosis of the target vessel lumen is visually assessed to be >=50% and =2 mm; 3. Two coronary angiographic images with projection angles differing by more than 25° are available to meet the requirements for 3D uFFR analysis.
Exclusion criteria
Exclusion criteria: 1. Lesions at the mouth of the vessel; 2. History of coronary artery bypass graft surgery; 3. Lumen narrowing caused by a myocardial bridge; 4. Poor quality of angiographic images, making vessel boundaries unclear or insufficient contrast agent filling.
