  1. Left ventricular mass index was graduated based on MRI measurements.
  2. A = late mitral inflow velocity; AVA = aortic valve area; AVR = aortic valve replacement; BSA = body surface area; CO = cardiac output, E = early mitral inflow velocity; E' = early tissue Doppler velocity at the septal mitral annuls, EF = ejection fraction; ELI = energy loss index; GLS = global longitudinal strain; LVM = left ventricular mass index; MRI = magnetic resonance imaging, P = pressure; S = systolic tissue Doppler velocity at the septal mitral annulus); SV = stroke volume; V = velocity
