CMR-FT technique was used to measure apical, middle and basal strain of left ventricle. Results showed ICC value was higher than 0.9 in all strain parameters, and meanwhile all strain parameters in AL-CA group and ATTR-CA group were lower than those in control group except for apical RS. However, there was no statistical difference between the AL-CA group's and ATTR-CA group. Strain evaluation could evaluate patients of CA, which may provide evidence for the treatment and diagnosis of CA.
