Key result
Higher coronary perivascular fat attenuation index (FAI) was associated with lower minimal lumen area and higher incidence of myocardial ischemia, providing incremental predictive value.

May refine ischemia prediction beyond stenosis; leaves open prospective validation before clinical use.
Is coronary perivascular fat attenuation index (FAI) associated with plaque parameters and myocardial ischemia?
Coronary perivascular fat attenuation index (FAI) may provide incremental predictive value for determining myocardial ischemia.
Li et al. (2021) studied this question. Higher coronary perivascular fat attenuation index (FAI) was associated with lower minimal lumen area and higher incidence of myocardial ischemia, providing incremental predictive value.
