Values in parentheses are percentages for categorical and SDs or IQR for continuous variables.
BSA, body surface area; LGE, late gadolinium enhancement; LVEDVI, left ventricular end-diastolic volume index; LVEF, left ventricular ejection fraction; LVESVI, left ventricular end-systolic volume index; LVMI, left ventricular mass index; MRF, mitral regurgitation fraction.
P-value <0.05 are shown in bold.
