Figure 3. Comparison of HW/BW ratio and myocardial infarct size among five groups. aP < 0.05 compared with sham-operated group; bP < 0.05 compared with control I/R group; cP < 0.05 compared with 2.5 mg/kg As-IV group; dP < 0.05 compared with 5 mg/kg As-IV group. As-IV, astragaloside IV; I/R, ischemia-reperfusion; HW, heart weight; BW, body weight.
