- •
The average distal curvature (
) of 48 LAD arteries is quantified from CCTA images.- •
Low values of
in the LAD are strongly correlated with the presence of stenosis.- •
Classification of arterial health status using Kd is faceable.
- •
Using a cut-off value of
= 0.0537 mm−1 yields accuracy and AUC of 75%.- •
The
could be an indication of a geometric risk factor for CAD.
