    The study analyzed the relationship between AI-derived CCTA features and coronary flow reserve (CFR) and fractional flow reserve (FFR-CT) in CAD patients.

  • 2

    CFR and FFR-CT showed poor agreement for ischemia detection, indicating distinct pathophysiological dimensions in assessing myocardial ischemia.

  • 3

    CFR reduction was linked to perivascular fat attenuation index and calcified plaque burden, while FFR-CT was associated with low attenuation and lipid plaques.

  • 4

    CCTA alone is insufficient for predicting abnormal CFR, highlighting the need for invasive assessments to confirm findings.

  • 5

    The study's findings are hypothesis-generating and call for future research incorporating invasive physiological assessments.
