  1. EDVi End-diastolic volume indexed to body surface area, EF Ejection fraction, ESVi End-systolic volume indexed to body surface area, LGE Percentage of scar represented as late gadolinium enhancement over the myocardial mass, Mi Myocardial mass index, SV Stroke volume. Kruskal-Wallis test was used
