Hemodynamics at different time-points in each group. (A) LVSP and (B) LVEDP were obtained via catheter method at five different time-points: i) Before AMI; ii) 2 h after occlusion; iii) 1 h; iv) 2 h; and v) 3 h after reperfusion. *P<0.05 vs. the control group, ^ΔP<0.05 vs. before AMI in the same group, ^#P<0.05 vs. 2 h after AMI in the same group. LVSP, left ventricular systolic pressure; LVEDP, left ventricular end-diastolic pressure; PGE₂, prostaglandin E₂.
