Long-term treatment of VPA restored cardiac function and scar size at 28 day after MI in rats. (a) and (b), Echocardiographic measurements of EF and FS of Sham, MI and MI + VPA rats at 28 days after MI. **, P < .01 vs Sham group; ##, P < .01 vs MI group; n = 9. (c) Representative images of heart sections by Masson's Trichrome staining. Scale bar: 2.5 mm (d) Quantitative analysis of infarct size expressed as percentage of left ventricle. **, P < .01, n = 6. All samples were analyzed by one way ANOVA followed by post-hoc Turkey HSD analysis. Data were expressed as mean ± SEM.
