Fig. 9

Diagnostic flow-chart suggesting a rational and evidence-based use of CT, CTA and invasive coronary angiography after stress-echocardiography. The width of the arrows graphically represents the percentage or number of patients who follow one or the other way in the flow-chart, depending on tests results. CAD = coronary artery disease. CT = computed tomography. CTA = computed tomography angiography, WMSI = wall motion score index
