Fig. 2. Cardiac function. A, Left ventricular development pressure (LVDP). B, Heart rate (HR). C, Rate pressure product (RPP). LVDP is the difference between left ventricular systolic pressure and left ventricular diastolic pressure, and it is presented as a percentage of pre-ischemic values. RPP was calculated as the product of LVDP and HR (RPP=LVDP*HR), and it is presented as mmHg*bpm/1000. Groups: Con, control (black circle); IR, ischemia-reperfusion (red square); IRX, IR+XJB (orange triangle); IRS, IR+SfA (blue diamond); IRXS, IR+XJB+SfA (green hexagon). *P<0.05, **P<0.01 vs. Con; ^&P<0.05 vs. IRX; ⁺P<0.05, ⁺⁺P<0.01 vs. IRS; ^#P<0.05, ^##P<0.01 vs. IRXS. n= 6-7 per each group.
