… Atherosclerosis. From wordnet.princeton.edu. Meaning of atherosclerosis. Atherosclerosis is a disease that affects the blood vessels called arteries, which carry blood to the organs of the body. Normal arteries allow blood to flow freely. However, these arteries can become hardened and narrowed by deposits called plaques. Plaque is made up of tiny particles of fat, cholesterol, waste material from cellular functions, fibrin and calcium. Atherosclerosis, also known as “hardening of the arteries,” occurs when cholesterol and other lipids begin to accumulate on the inner walls of damaged blood vessels. Atherosclerosis (sometimes called “hardening” or “clogging” of the arteries) is the buildup of cholesterol, fatty cells and inflammatory deposits (called plaque) on the inner walls of the arteries that restrict blood flow to the heart. Atherogenesis is driven by an interplay of inflammation and injury to vessel wall cells.

Atherosclerosis is a type of arteriosclerosis, which is further classified into three different types: 1) atherosclerosis (the build-up of fatty deposits in the inner lining of the arteries); 2) arteriolosclerosis (the thickening of the arterial walls); and 3) Mönckeberg’s arteriosclerosis (which is the calcification of the arterial walls due to loss of elastic fibers and muscles in the body). Also found in: Dictionary, Thesaurus, Encyclopedia. Atherosclerosis is the build up of a waxy plaque on the inside of blood vessels. In Greek, athere means gruel, and skleros means hard. Atherosclerosis is often called arteriosclerosis. Arteriosclerosis (from the Greek arteria, meaning artery) is a general term for hardening of the arteries. Arteriosclerosisoccurs when the blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff — sometimes restricting blood flow to your organs and tissues. The term atherosclerosis is derived from the Greek "athero," meaning gruel, or wax, corresponding to the necrotic core area at the base of the atherosclerotic plaque, and "sclerosis" for hardening, or induration, referring to the fibrous cap of the plaque's luminal edge. Atherosclerosis leads to the narrowing of the artery, which in turn reduces the flow of blood passing through it. Atherosclerosis is a complex process by which arteries become progressively narrowed, impairing the supply of oxygen and nutrients to tissues. Arteriosclerosis and atherosclerosis are sometimes used to mean the same thing, but there's a difference between the two terms. 1. You may be referred to a doctor that specializes in heart diseases (cardiologist). What does "sclerosis" mean? Atherosclerosis (also known as hardening of the arteries or stiffening of the arteries or arteriosclerosis) is a disease in which plaque builds up inside your arteries. atherosclerosis. Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death. These plaques are formed by deposits of cholesterol and other lipids, calcium, and large inflammatory cells called macrophages. The anatomy of a normal artery is shown in Fig. Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. Risk factors may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and eating saturated fats. a narrowing of the arteries that can significantly reduce the blood supply to vital organs such as the heart, brain and intestines. Find out what causes it, what symptoms to look for, treatment options, prevention tips, and more. Impaired blood flow can result in ischemia and cause symptoms such as angina or intermittent claudication. The early lesions of atherosclerosis consist of subendothelial accumulations of cholesterol-engorged macrophages, called ‘foam cells’. What does atherosclerosis mean?

Atherosclerosis, the most common form of arteriosclerosis, is a complex process that begins with the appearance of cholesterol-laden macrophages (foam cells) in the intima of an artery. atherosclerosis ( n.) a stage of arteriosclerosis involving fatty deposits (atheromas) inside the arterial walls, thus narrowing the arteries; Synonyms: coronary artery disease. Atherosclerosis is a disease process which is triggered by sometimes subtle physical or chemical insults to the endothelial cell layer of arteries. Atherosclerosis is a condition that narrows and hardens blood vessels. 1. In this condition, the innermost layer of the blood vessels (endothelium) is constricted by the deposition of fat, calcium and cellular debris. And Over time, plaque hardens and narrows your arteries. What is atherosclerosis? Atherosclerosis is a chronic, progressive disease in which plaques build up in the walls of arteries.
