Comparison of LV wall thickness for all 16 segments in patients who had apical wall thickness < 15 mm without a family history or < 13 with a family history of HCM) at baseline (a) and at follow-up (b) for both groups. There were no significant differences both in basal (seg 1–6) and middle (seg 7–12) at either baseline and follow-up. However, there were significant differences in apical segments (seg 13–16) both at baseline and follow-up. FH family history, Seg segment
