Data are presented as means ± SD (95% CI) or median (interquartile range) as appropriate. *p<0.05 for comparison between stenosed and remote segments; †p<0.05 for comparison between remote to ischemia and normal segments; ‡p<0.05 for comparison between stenosed and normal segments. BOLD, blood oxygen level-dependent; MBF, myocardial blood flow; SI, signal intensity.
