Figure 2

(A) Typical echocardiographic images of the hearts of rats from the Sham, Sham-RES, AMI, and AMI-RES groups. (B) Heart rate (HR). (C) Left ventricular end-systolic diameter (LVESD). (D) Left ventricular end-diastolic diameter (LVEDD). (E) Fractional shortening (FS). (F) Ejection fraction (EF). The data are expressed as the means ± SDs. ∗, P < 0.05 and ∗∗, P < 0.01 compared with the Sham group. #, P < 0.05 and ##, P < 0.01 compared with the AMI group.
