Atherosclerosis is the underlying cause of most acute coronary syndromes (ACS) such as myocardial infarction and unstable angina, which are major causes of mortality in the Western world. Although the role of necrosis in atherosclerosis remains ill-defined, a growing body of evidence suggests that necrotic death stimulates atherogenesis through induction of inflammation and enlargement of the necrotic core.

You may be referred to a doctor that specializes in heart diseases (cardiologist). Atherosclerosis is a specific type of arteriosclerosis. As the underlying cause of heart attack, stroke, and peripheral vascular disease, atherosclerosis is the major cause of death and morbidity in the United States and the industrial world ().The discovery by Virchow more than 100 years ago that atheroma contained a yellow … Terms in this set (34) Pathophysiology: What is Atherosclerosis?

Atherosclerosis is common. Atherosclerosis -- or hardening of the arteries -- is the leading cause of heart attacks, strokes, and peripheral vascular disease. Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. This streak is made up of smooth muscle cells, cholesterol, and macrophages (a type of white blood cell). The fatty streak phase alone does not cause any noticeable symptoms but can progress into a more dangerous phase of atherosclerosis called a fibrous plaque. Fibrous plaque: A fibrous plaque develops within the inner layer of the vessel. In this condition, the innermost layer of the blood vessels (endothelium) is constricted by the deposition of fat, calcium and cellular debris. After all, you can't see any buildup of waxy plaque that may exist in your arteries, and the disease doesn't make itself known until it's advanced. Atherosclerosis in Cardiovascular Disease.
