The head-to-head comparison of the changes of all 16-segmental thicknesses of the left ventricle (LV) in patients who did not meet HCM criteria (wall thickness ≥ 15 mm without family history or ≥ 13 with a family history of HCM) at baseline or at follow-up between group 1 (a) and group 2 (b). at follow-up, the thickness of all LV segments significantly increased. The thickness of apical portion (segment 13–16) increased the most. Seg segment
