The data are presented as mean (SD). The difference of each parameters between the three groups was calculated using analysis of variance (ANOVA) and between the two groups with Student’s t-test and the results presented as p-value. LV, left ventricle; LGE, late gadolinium enhancement.*p < 0.01 versus group 1, **p < 0.05 versus group 1,‡p < 0.05 versus group 2.
