General characteristics of sham and post-MI rats. (a) Echocardiographic EF and FS measurements and plasma BNP levels of sham and post-MI rats at 4 weeks, 8 weeks, and 12 weeks post-MI (A). LVIDd, LVIDs, and cardiomyocyte size values of sham and post-MI rats at 4 weeks, 8 weeks, and 12 weeks post-MI (B). (b) Haematoxylin/eosin staining (upper) and Masson's trichrome staining (lower) of the left ventricle of sham and post-MI rats at 4 weeks, 8 weeks, and 12 weeks post-MI. ∗P < 0.05 versus the corresponding sham group. EF: ejection fraction; FS: fractional shortening; BNP: brain natriuretic peptide; MI: myocardial infarction; LVIDd: left ventricular internal end diastolic dimension; LVIDs: left ventricular internal end systolic dimension.
