From: Layer‐specific strain echocardiography may reflect regional myocardial impairment in patients with hypertrophic cardiomyopathy

  1. TGLS transmural gradient of longitudinal strain; HCM hypertrophic cardiomyopathy. The chi-square test was performed for 2-group comparisons among the 3 groups. The p values obtained in all the tests were < 0.001. A p value of < 0.017 was assumed to be significant.
