Kaplan-Meier survival curves for native T1, ECV and LGE. (a) Patients categorized by median native T1 (1456 ms) did not differ significantly in survival probability (74.1% vs. 65.7% at the 8th month, Tarone-Ware P = 0.069). (b) Patients with ECV < 44.0% and ECV ≥ 44.0% differed significantly in survival probability (94.9% vs. 54.6% at the 8th month, log rank P = 0.001). (c) Patients with no/patchy LGE and global LGE differed significantly in survival probability (90.7% vs. 56.2% at the 8th month, log rank P = 0.001). LGE = late gadolinium enhancement, ECV = extracellular volume
