Fig. 8From: 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 angiogramsIncremental usefulness based on model chi square of adding imaging data over baseline demographics and clinical variables to predict CAD > 50%. CAD = coronary artery disease. CFR-LAD = coronary flow reserve of the left anterior descending coronary arteryBack to article page
