  1. All data are expressed as the mean ± SD, and all strains are expressed in percentages; GRS, global radial strain; GCS, global circumferential strain; GLS, global Longitudinal strain; *compared with control group, P < 0.05; a: compared with group I, P < 0.05; b: compared with group II, P < 0.05; c: compared with group III, P < 0.05.
  2. Bolded: statistically significant P-values.
