Values are given as frequency n (percentage%), mean (SD = standard deviation); or median (IQR = interquartile range). LV, left ventricle; EF, ejection fraction; EDV, end-diastolic volume; SV, stroke volume; LGE, late gadolinium enhancement; ECV, extracellular volume. The statistically significant p ≤ 0.05 is represented by bold values.
