The echocardiogram results showed a significant improvement in cardiac function in rats after icariin treatment. A M-mode echocardiography was used to capture representative images of SD rats before and after myocardial infarction (MI) in the icariin treatment group, MI group, sham group, and control group. B The left ventricular ejection fraction (EF), left ventricular fractional shortening (FS), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD) were subjected to comparative analysis among different MI groups receiving various dosages of icariin at 0, 15, 30, 60, and 90 days after MI. *P < 0.05, **P < 0.01
