  1. TGLS transmural gradient of longitudinal strain; HCM hypertrophic cardiomyopathy. ap < 0.001, compared with patients with HCM with normal segments. bp < 0.001, compared with healthy controls. cp < 0.01, compared with healthy controls; no significant difference was observed between the other two pairs.
