Ischemia-reperfusion injury activates early extracellular matrix processing and expression of endostatin in the heart with differential effects of temperature.

abstract：:Both the severity and duration of postischemic myocardial dysfunction ("stunned" myocardium) are unpredictable and may vary considerably between subjects that underwent apparently similar ischemic insults. To explain this heterogeneous response of the heart to ischemia and reperfusion, we investigated the determinants...
