Due to substantial differences in septal wall thickness (A), subsection analysis was performed in patients with mild to moderate LV hypertrophy (IVS 11–15 mm, as shown by the red bars in A-B). LV ejection fraction was similar between the four subgroups (C), whereas only patients with cardiac amyloidosis exhibited a higher LV mass index and T1 values compared to all other groups (D and F). MCF was lower in patients with cardiac amyloidosis compared with athletes and HHD but like HCM (E). Atypical LGE differentiated between amyloidosis and all other hypertrophy forms, between athletes and HHD or HCM, but not between athletes and HHD (G). %normal myocardium differentiated between all hypertrophy forms, except between HCM and amyloidosis (H)
