Atherosclerosis is a chronic disease in which the walls of the arteries thicken and descend, the lumen narrows, and blood circulation becomes difficult. It is characterized by the appearance of atherosclerotic plaques in the vascular walls. Their formation is the result of fat accumulation and the proliferation of connective tissue. Plaques are mainly formed in large blood vessels, causing narrowing and deformation of the blood vessel, which is the result of reduced blood supply to the organs and, as a result, their ischemia.
