Transmural extent of LGE was evaluated on a 16-segment model, and transmurality was graded on a 5-point scale: grades\u20140, absence; 1, 1 to 25%; 2, 26 to 50%; 3, 51 to 75%; 4, 76 to 100%. Median follow-up duration was 65.5 months (interquartile range\u2009=\u200927.5\u201395.3 months).

During the follow-up, all-cause mortality and readmission for congestive heart failure occurred in 29 and 8 patients, respectively. The cumulative incidence of the primary endpoint was 31.3 and 46.8% at 5 and 10 years, respectively. Multivariable analysis demonstrated that the number of segments with LGE grade 4 was a significant risk factor (hazard ratio 1.42, 95% confidence interval 1.10\u20131.83, p\u2009=\u20090.007) for the primary endpoint among the variables assessed by CMR.
