Evaluation of the Effects of Schisandra chinensis on the Myocardium of Rats with Hyperthyroid Heart Disease by Using Velocity Vector Imaging Combined with the Estimation of p53 Expression and Calmodulin Activity

Table 1

Velocity vector imaging parameters of the groups of rats (n = 10).

Parameters	CON	HHD	SC
Vs (cm/s)	0.270 ± 0.132	0.102 ± 0.050^b	0.292 ± 0.145^d
Vd (cm/s)	0.248 ± 0.108	0.119 ± 0.064^a	0.288 ± 0.129^d
S (%)	8.851 ± 6.887	1.604 ± 1.178^b	6.492 ± 3.674^c
sSR (1/s)	1.222 ± 0.864	0.512 ± 0.290^a	1.287 ± 0.781^c
dSR (1/s)	1.270 ± 1.033	0.516 ± 0.328^a	1.266 ± 0.684^c

The results are represented as the mean ± standard deviation (SD). ^a vs. CON group, ^b vs. CON group, ^c vs. HHD group, ^d vs. HHD group (CON, control group; HHD, hyperthyroidism heart disease model group; SC, Schisandra chinensis group; Vs, systolic velocity; Vd, diastolic velocity; S, strain; sSR, systolic strain rate; dSR, diastolic strain rate).
