R-values and P-values are shown. Abbreviations: LVEF, left ventricular ejection fraction; LVEDVI, left ventricular end-diastolic volume index; LVESVI, left ventricular end-systolic volume index; LVMI, left ventricular mass index; GLS, global longitudinal strain; ECV, extracellular volume fraction. Bolded values indicate P < 0.05.
