T3 improved cardiac function after I/R injury. A, Left ventricular mode echocardiograms in short axis at 7th day after operation. B, Left ventricular ejection fraction (%LVEF). C, Fractional shortening (%FS). D, Left ventricular end‐systolic diameter (LVESd). E, Left ventricular end‐diastolic diameter (LVEDd). The values were expressed as the mean ± SD in the experiment. n = 6. ·P < .05 vs Sham, ··P < .01 vs Sham, ····P < .0001 vs Sham; ^* P < .05 vs I/R, ^** P < .01 vs I/R, ^**** P < .0001 vs I/R; ^## P < .01 vs I/R + T3, ^### P < .001 vs I/R + T3
