Inflammation is now considered a key component of atherosclerosis, from fatty streak formation to plaque rupture, subsequent thrombosis, and progressive mechanical and dynamic obstruction. Rupture of the arterial plaque's fibrous cap exposes tissue factors present in the necrotic core, triggering inflammatory signaling, cell adhesion, and the coagulation cascade that eventually ...
