  1. Values are mean ± SD. Measurements are an average of the first and second study.
  2. *Averaged segmental stress:rest maximal normalized upslopes.
  3. Number of myocardial segments with reversible ischemia by qualitative analysis.
  4. Summed segmental transmural stress:rest score (1 = normal, 2 = subendocardial defect, 3 = transmural defect).
  5. §Summed segmental hypoenhancement stress:rest score (1 = normal, 2 = grey defect, 3 = black defect).
  6. ||Summed segmental infarct score divided by number of segments analyzed (1 = normal, 2 = subendocardial infarct, 3 = transmural infarct).
  7. #p < 0.020 for control vs. case.
