From: Equivocal tests after contrast stress-echocardiography compared with invasive coronary angiography or with CT angiography: CT calcium score in mildly positive tests may spare unnecessary coronary angiograms

Fig. 2

Pre-specified criteria suggested in our lab to define equivocal contrast stress-echocardiograms (who are indicated CTA) based on wall motion and the other available variables. Additionally to the standalone wall motion score index delta criterion, patients with 2 minor criteria were also defined equivocal tests and indicated CTA, while more than 2 minor or two major were also defined positive tests and indicated iCA. Yellow colour represents minor criteria, orange means major criteria, but unrelated to wall motion assessment. CTA = CT angiography, iCA = invasive coronary angiography, CFR-LAD = coronary flow reserve of the left anterior descending coronary artery. Yellow boxes identify minor criteria, Orange are major non-WM criteria, while light red and dark red indicate WM mild and more-than-mild ischemia
