Test Performance of Exercise CMR. a Change in global χ² value of the multiparametric “4-in-1” approach consisting of inducible regional wall motion abnormalities (RWMA), perfusion defects, late gadolinium enhancement (LGE) and peak exercise cardiac index (Peak_CI). The clinical model consisted of age, sex and coronary risk factors (diabetes, hypertension, dyslipidaemia and smoking history). b Receiver operating characteristic curves to compare the discriminative abilities of the different models. A multiparametric model consisting of inducible RWMA, perfusion defects, LGE and Peak_CI offered the highest discrimination between those with and without significant coronary artery disease confirmed on fractional flow reserve
