*Averaged segmental stress:rest maximal normalized upslopes.
^†Number of myocardial segments with reversible ischemia by qualitative analysis.
^‡Summed segmental transmural stress:rest score (1 = normal, 2 = subendocardial defect, 3 = transmural defect).
^§Summed segmental hypoenhancement stress:rest score (1 = normal, 2 = grey defect, 3 = black defect).
