- Original description
In this prospective cohort study, 250 patients with suspected or known CAD and at least one intermediate coronary lesion (50-70% stenosis) who had a NiFFR value greater than 0.80 underwent coronary computed tomography angiography (CCTA) with NiFFR assessment. Patients were followed for one year to monitor for MACERead full original descriptionShow less
Evaluation of the Ability of CTFFR to Determine Non-significant Lesions of Coronary Disease Based on MACE in One-year Follow-up of Patients (Seeing Beyond the Stenosis: CTFFR and MACE in a One-Year Follow-Up)
In this prospective cohort study, 250 patients with suspected or known CAD and at least one intermediate coronary lesion (50-70% stenosis) who had a NiFFR value greater than 0.80 underwent coronary computed tomography angiography (CCTA) with NiFFR assessment. Patients were followed for one year to monitor for MACE
Inclusion: Patients were enrolled if they had at least one intermediate coronary lesion (classified as 50-70% diameter stenosis on visual judgment) on CCTA and then underwent FFR testing.
Exclusion: Patients having past coronary artery bypass graft surgery (CABG); previous PCI in the target vascular; contrast allergy; significant renal impairment define with eGFR < 30 mL/min/1.73 m²; poor image quality that prevented appropriate CCTA or CT-FFR analysis.
