From: Mild hypothermia reduces cardiac post-ischemic reactive hyperemia
Coronary reactive hyperemia. The figure illustrates coronary blood flow expressed as average peak velocity (APV), in cm/s, in the LAD at baseline samples (A), at samples during the LAD occlusion (ischemia) (B), and at 10 sec intervals during the time of the reperfusion period (C), i.e., the phase of post-ischemic reactive hyperemia. The hypothermic group (n = 8) had a significant 43% lower peak flow than the normothermic group (n = 8) during the period of reactive hyperemia. There was no observed difference in coronary flow between the groups during baseline or after 7 minutes from reperfusion.
