Results
For all patients,
significant or even maximum degree of hypertrophic changes have been found at the anterior- and posterior-septal segments of the basal myocardium.
At the same time,
myocardium hypertrophy was minimal at the apical segments.
The native T1 value was around 1300±44ms (p<0.01),
that is significantly higher than the control group (1093±23,7ms).
Mean post- contrast myocardium T1 were (497±62ms p>0,05).
Mean of ECV was 28±4,5%,
which was higher then the group (25,8±1,9%).
We obtained individually association of every value (EDWT,
native T1,
LGE) with the strain values.
The EDWT and native T1 had statistically significant association with circumferential (Ecc-FT) and radial (Err-FT) strain values (r=0,5,
p<0,0001).Weak correlation of ECC-FT,
Err-FT and ECV (r=0,2,
p>0,05).
The LGE didn’t have any statistically significant association with the strain values.
The midwall fractional shortening had weaker correlation with native T1 values (r=0,5 p>0,05). The circumferential (Ecc-FT) and radial (Err-FT) strain values were significantly higher than control group (r=0,58,
p> 0,05).
