Severe inflammatory reactions (complement activation and IL-1, IL-6, IL-8, and IL-10 elevation), blood coagulation, platelet activation with formation of thromboxane A2, alteration of soluble E-selectin (sE-selectin) and P-selectin (sP-selectin), and whole-body ischemia/reperfusion injury, which occur in sepsis, also occur in post-cardiac arrest injuries [6, 9, 34, 35]. This evidence concerns the gene IL6 and cardiac arrest.
