AMVLi indicates indexed anterior mitral valve leaflet (length); BSA, body surface area; ECV, extracellular volume; G+LVH‐, genotype‐positive; left ventricular hypertrophy‐negative; LA, left atrium; LGE, late gadolinium enhancement; LV, left ventricle/ventricular; LVEDVi, indexed left ventricular end‐diastolic volume; LVESVi, indexed left ventricular end‐systolic volume; Massi, indexed mass; MBF, myocardial blood flow; MPR, myocardial perfusion reserve; MWT, maximum wall thickness; and SV, stroke volume.

^*indicates significant P value <0.05.
