  1. Values expressed as n (%) or mean ± SD or median (interquartile range). The p values reflect the comparison between 2 groups (controls vs. All HCM). The p’ values reflect the comparison between 3 subgroups (controls vs. LGE (−) vs. LGE ( +)) or 2 subgroups (LGE (−) vs. LGE ( +)), respectively. LGE, late gadolinium enhancement; LVOTG, peak left ventricular outflow tract gradient; NYHA, New York heart association; ACE, angiotensin-converting enzyme; ARB, angiotensin-receptor blocker; Nt-proBNP, N-terminal pro b-type natriuretic peptide; hs-cTnI, high-sensitivity cardiac troponin I. * < 0.05 vs. controls. # < 0.05 vs. LGE (−).
