Clinical and prognostic incremental value of FFRCT in screening of patients with obstructive coronary artery disease.

Background: Coronary computed tomography angiography (CCTA) -derived fractional flow reserve (FFR) is recommended to evaluate the functional consequences of obstructive coronary artery disease (OCAD). Real-world incremental impacts of FFR use still remains under debate.

Methods: 1601 patients with suspected OCAD on CCTA (>50 ​% stenosis), including 808 (50.
