Mean arterial pressure.

<p>Blood pressure elevated significantly after aortic clamping and remained elevated throughout the ischemic period in the IR (ischemia-reperfusion) group (broken line). Levosimendan treatment withheld this elevation during ischemia (unbroken line). At the onset of reperfusion a significant drop occurred, but after that, mean arterial pressure increased and then remained elevated in both IR and Levosimendan groups without significant difference between the groups. Sham operated group is marked with a dotted line. Values are expressed as means ± SD, †: p<0.01 vs. Sham, ‡: p<0.001 vs. Sham, §: p<0.001 vs. IR.
