Figure 1. Tanshinone IIA improved cardiac functions against MI/RI. (a) Representative echocardiograms for each group. (b) Quantification of AV Peak Vel, EF% and FS% (n ≥ 3 per group). (c) Levels of CK, CK-MB and LDH in rat serum (n ≥ 3 per group). (d) Representative TTC-stained heart images and quantification of infarct sizes. Percentage infarct size =(Infarct size / viable size) × 100% (n ≥ 3 per group). (e) Representative HE staining of heart transverse sections (scale bar = 50 μm).

MI/RI: myocardial ischemia-reperfusion injury; *p < 0.05 compared with the sham group; #p < 0.05 compared with the MI/RI group; TCC: 2,3,5-Triphenyltetrazolium chloride; HE: hematoxylin and eosin.
