Clinical model 1 (regional CFRCT-MP <2.0 + epicardial fat volume). Clinical model 2 (regional CFRCT-MP <2.0 + epicardial fat volume + FFNC volume). Clinical model 3 (regional CFRCT-MP <2.0 + epicardial fat volume + FFNC volume + regional hyperemic MBF). CMD, coronary microvascular dysfunction; IDI, integrated discrimination improvement; NRI, net reclassification index; CFR, coronary flow reserve; CT-MP, computed tomography myocardial perfusion; FFNC, fibrofatty and necrotic core component; MBF, myocardial blood flow.
