Establishment of a rat AMI model. Electrocardiogram of rats (a). A normal wave can be seen in the sham group. Arrow indicates the pathologic Q wave in an LAD ligated rat. The representative echocardiography (b). A sham rat shows a normal cardiograph. Contraction of the left ventricle anterior walls in the LAD ligated animal was weaker than in sham control animal. TTC staining of a myocardial section (c). The black arrow indicates the infarction area which occupied 19% in whole left ventricles.
