CI, confidence interval; CMR, cardiac magnetic resonance; FT, feature tracking; GCS, global circumferential strain; GLS, global longitudinal strain; GRS, global radial strain; HR, hazard ratio; LGE, late gadolinium enhancement; LV, left ventricle; LVEDV, left ventricle end diastolic volume indexed; LVEF, left ventricle ejection fraction; RV, right ventricle; RVEF, right ventricle ejection fraction.

Only significant variables were reported in univariable analysis.

MACEs were considered as the study primary outcome measure and were defined as a composite of: (a) cardiovascular death, (b) cardiac transplant or destination therapy ventricular assist device for end-stage heart failure (HF), (c) hospitalization for life-threatening ventricular arrhythmias or implanted cardioverter defibrillator appropriate intervention on sustained ventricular tachycardia >185 beats per minute or ventricular fibrillation.
