Key result
Mild hypothermic ischemia-reperfusion significantly increased the tissue content of Arresten and Endorepellin compared to baseline, whereas deep hypothermia was not associated with significant release.
Why the study?
Does deep vs mild hypothermia during ischemia-reperfusion affect extracellular matrix processing and basement membrane structure in a porcine model?
Does deep vs mild hypothermia during ischemia-reperfusion affect extracellular matrix processing and basement membrane structure in a porcine model?
Absolute Event Rate: 0.56% vs 0.17%
p-value: p=0.001
Deep hypothermia during ischemia-reperfusion prevents the early temperature-dependent processing of collagen IV and Hspg2, suggesting a protective effect on the myocardial basement membrane compared to mild hypothermia.

Deep hypothermia may preserve myocardial basement membrane in porcine ischemia-reperfusion; hypothesis-generating for temperature-specific cardioprotection in humans.
Lauten et al. (2014) studied Myocardial ischemia-reperfusion injury (n=30). Mild hypothermic (32°C) vs Deep hypothermic (4°C) ischemia-reperfusion vs. Control (60 min of cardiopulmonary bypass without myocardial ischemia) was evaluated on Tissue content of Arresten (ARR) within 150 min of reperfusion (p=0.001). Mild hypothermic ischemia-reperfusion significantly increased the tissue content of Arresten and Endorepellin compared to baseline, whereas deep hypothermia was not associated with significant release.
