Conventional echocardiographic parameters
No difference was showed in IVSTd and PWTd among three groups (both P<0.05). In group C, E/ mean e’, LVDs and LVDd were increased (all P<0.05), while E/A, LVEF, Sept e’ and Lat e’ were decreased (all P<0.05) compared to groups A and B. In group B, we found that E/mean e’ was increased, while Sept e’ and Lat e’ were decreased compared with group A (all P<0.05). There were no obvious difference in terms of LVDs, LVDd, E/A and LVEF between groups A and B (all P>0.05).(Shown in Table 2)
3D and 3D-STEparameters
Compared with groups B and A, LVEDV and LVESV were obviously increased (all P<0.05), whereas LVEF was obviously declined in group C (P<0.05). The parameters of LVEDV, LVESV and LVEF were no obvious differences in groups A and B (all P>0.05).The patients in group C had higher LAVImax compared to groups A and B, and LAVImax level for group B was higher than for group A. GLS, GRS, GCS, GAS in group C were obviously lower (all P<0.05) than those in groups A and B. GLS, GCS and GAS in group B were lower than those in group A (all P<0.05) and GRS was also reduced, but there was no difference (P>0.05). (Shown in Table 3 and Figure 1)
