Popis: | AIMS We sought to compare the diagnostic accuracy of basal stenosis resistance index (BSR), instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) for stenosis-specific myocardial ischaemia identified by means of a combined reference standard of myocardial perfusion scintigraphy and the hyperaemic stenosis resistance index. METHODS AND RESULTS BSR and FFR were determined for 299 coronary stenoses, iFR was determined for 85 coronary stenoses (iFR cohort). The discriminative value for stenosis-specific myocardial ischaemia was compared by means of the area under the receiver operating characteristic (ROC) curves (AUC). Classification agreement with the reference standard was determined according to ROC curve-derived ischaemic cut-off values, as well as according to clinical cut-off values, equivalent to the 0.80 FFR cut-off. Across all stenoses, the discriminative value of BSR and FFR was equivalent (AUC: 0.90 and 0.91, respectively, p=0.46). In the iFR cohort, the discriminative value was equivalent for BSR, iFR, and FFR (AUC: 0.88, 0.84, and 0.88, respectively; p≥0.20 for all). At both ischaemic as well as clinical cut-off values, classification agreement with the reference standard was equivalent for BSR and FFR across all stenoses, as well as for BSR, iFR, and FFR in the iFR cohort. CONCLUSIONS BSR, iFR, and FFR have equivalent diagnostic accuracy for the detection of ischaemia-generating coronary stenoses. |
