Data are presented as median [IQR]. versus wt. LVmass: left ventricular mass; CO: cardiac output; SV: stroke volume; FS: fractional shortening; EF: ejection fraction; E/A: E/A ratio; gLS/gLSR: global longitudinal strain/strain rate; gRS/gRSR: global radial strain/strain rate; gCS/gCSR: global circumferential strain/strain rate.
