Global CAAS ≤9.22% | 79/92 (86%) | 126/179 (70%) | 79/132 (60%) | 126/139 (91%) |
DTS ≤−1.12 | 66/92 (72%) | 133/179 (74%) | 66/112 (59%) | 133/159 (84%) |
Global CAAS ≤9.22% or DTS ≤−1.12 | 84/92 (91%) | 91/179 (51%) | 84/172 (49%) | 91/99 (92%) |
Global CAAS ≤9.22% and DTS ≤−1.12 | 61/92 (66%) | 168/179 (94%) | 61/72 (85%) | 168/199 (84%) |
CAAS indicates circumferential ascending aortic strain; CAD, coronary artery disease; DTS, Duck Treadmill Score; NPV indicates negative predictive value; PPV, positive predictive value.
