  1. EDM = enddiastolic mass; EDV = enddiastolic volume; EF = ejection fraction; ESV = endsystolic volume; LGE = Late gadolinium enhancement; LV = left ventricular; Presence of LGE = Number of patients in whom LGE was detectable; LVEDD = left ventricular enddiastolic diameter; PWT = posterior-wall-thickness; RVEDD/RVESD = right ventricular enddiastolic/enddiastolic diameter; SV = stroke volume; SWT = Septal-wall-thickness; (Mean value ± standard deviation).
