Comparison of global left ventricle MBF and CFR between the volunteers and patients. Rest MBF showed no significant difference between the volunteers and patients (a). However, the stress MBF (b 2.04 ± 0.62 vs 3.56 ± 0.91 ml/min/g, p = 0.0002) and whole CFR (c 2.75 ± 0.81 vs 4.54 ± 0.66, p = 0.0002) of the volunteers were significantly higher than those of the patients
