It has been discovered that IL-6 isrelated to the pathophysiology of ischemic cardiovascular events, such as unstable angina and ACS [11].Angiotensin II-mediated vasoconstriction, oxygen radical release, and endothelial dysfunction can be caused by IL-6-induced up-regulationof angiotensin II type 1 receptor gene expression. Here, IL6 is linked to endothelial dysfunction.
