Endothelial layer of normal coronary arteries will be damaged by
the presence of risk factors, among others: hemodynamic factors such as
hypertension, vasoconstrictor agents, mediators (cytokines) from the blood
cells, cigarette smoke, atherogenic diet, increased blood sugar levels and
oxidation of LDL-C.
This damage causes the endothelial cells produce a cell adhesion
molecule such as silicon (interleukin -1, (IL -1)); tumor necrosis factor alpha
(TNF-alpha)), chemokines (monocyte chemoattractant factor 1, (MCP-1; IL-8 ),
and growth factor (bFGF). Cells Inflammation as Monocytes and T-lymphocyte
entry into the endothelial surface of the endothelium and migration into the
sub-endothelial. Monocytes then differentiate into macrophages and take LDL and
then the macrophages become foam cells .
Oxidized LDL causes endothelial cell death and result in
inflammatory responses. In addition, there was the response of angiotensin II,
which cause vasodilation and trigger protombik effects involving platelets and
coagulation factors.
As a result of endothelial damage occurred and formed a protective
response fibrofatty and fibrous lesions, plaques atherosklerosik triggered by
inflammation. Plaques that occur can be unstable (vulnerable) and ruptures that
could lead to acute coronary syndrome.
