  1. Numbers are presented as percentages (with 95% confidence intervals)
  2. Obstructive CAD = coronary artery disease (defined as ≥ 70% stenosis in any epicardial coronary artery); LGE = late gadolinium enhancement. Step 1 abnormal: (1) regional wall-motion abnormalities, and/or subendocardial/transmural hyperintensity on T2-weighted and/or LGE in ≥ 2 segments or (2) at least 2 of 3 sequences abnormal in a single segment. Step 2 abnormal (only performed when step 1 was normal or equivocal): persistent subendocardial/transmural perfusion defect in ≥ 2 adjacent segments. Step 3 abnormal: abnormal results step 1 or 2
