(a) Final model of Cox multivariate analysis for all-cause mortality

	Hazard Ratio	95% CI	P value
ACS in the follow-up	6.7	2.9−15.8	<0.001
LVEF on echocardiography (≤30%)	4.2	2.0−9.0	<0.001
QTc interval (≥460 msec)	2.8	1.5−5.4	0.002
LV mass (≥220 g)	2.9	1.3−6.6	0.009
TotalLGE burden (≥ 40% LV mass)	3.4	1.3−8.8	0.012
Heart rate (>75 bpm)	2.0	1.0−3.8	0.041

(b) Final model of Cox multivariate analysis for MACE

	Hazard Ratio	95% CI	P value
Total LGE burden (>40% LV mass)	3.3	1.7−6.3	<0.001
CMR myocardial stress induced perfusion abnormality	2.1	1.4−3.2	<0.001
LM or 3−vessel CAD	1.9	1.4−2.8	<0.001
LVEF on echocardiography (≤30%)	2.5	1.4−4.4	0.002
Smoking	1.5	1.0−2.2	0.038

ACS = acute coronary syndrome; LV = left ventricle; LVEF = left ventricle ejection fraction; QTc = corrected QT interval; LGE = late gadolinium enhancement; CMR = cardiovascular magnetic resonance; MACE = major adverse cardiac events; LM = left main coronary artery; CAD = coronary artery disease.
