5 Fig 4 Endothelial cells produce and secrete several factors under normal circumstances to maintain the vessel integrity. During ischemia or injury, there is a decrease in the production of nitric oxide and prostacyclin but an increase in the production of endothelin. There is also an activation of leukocytes and an increase in the presence of endothelial adhesion molecules. In reperfusion injury, there is leukocyte adherence, movement through vascular intima, capillary leakage, and production of cytokines, prostanoids, and superoxides that cause further cellular damage, edema, and fluid sequestration.

6 Fig 5 Schematic representation of important inflammatory mediators with cardiotoxic potential released from activated neutrophils. O2− = superoxide anion; HOCl = hypochlorous acid; H2O2= hydrogen peroxide; MPO =myeloperoxidase; E = elastase; C = collagenase; LTB4 = leukotriene B4; PAF = platelet-activating factor.
