Figure 3: Cardiac function evaluation by MRI.

(a) Representative MRI image. In the MSCs group, LVEF was significantly increased at the 4^th week compared with the 1^st week, and ESV was significantly decreased. However, there were no significant differences in the control group. (b) Histogram shows cardiac function changes between the 1^st and 4^th week in the two groups. LVEF improved significantly in the MSCs treated group. ^#P < 0.01.
