Table 1 Baseline characteristics of the patients and cardiac magnetic resonance (CMR) functional results. Patients are classified according to the results of perfusion (PERF) and late gadolinium enhancement (LGE) visual assessment as four groups: PERF + LGE+ (perfusion abnormality positive, LGE positive), PERF + LGE- (perfusion abnormality positive, LGE negative), PERF-LGE+ (perfusion abnormality negative, LGE positive) and PERF-LGE- (perfusion abnormality negative, LGE negative)
