Myocardial infarct size expressed as a percentage of the left ventricular area at risk in protocol 2. CON = control; HG = hyperglycemia; ATR = atractyloside; MIL30 = 30 μg/kg milrinone, LEV100 = 100 μg/kg levosimendan. Data are mean ± SD. *Significantly (P < 0.05) different from CON. §Significantly (P < 0.05) different from HG-CON. †Significantly (P < 0.05) different from the group without ATR.
