  • Values are mean (SD).

  • CVR, coronary vasodilator reserve in the biopsied region (corrected for rate–pressure product); FDG, [18F]-fluorodeoxyglucose uptake in the biopsied region; LVEF, global left ventricular ejection fraction; MBF, myocardial blood flow in the biopsied region (corrected for rate–pressure product); RPP, rate–pressure product (basal and peak dobutamine); WMSI, wall motion score index in the biopsied region.
