Atherosclerosis
|
|
Atherosclerosis Also known as arteriosclerosis, atherosclerosis results from the accumulation of cholesterol-laden plaque in artery walls. Plaque accumulation causes a narrowing and a loss of elasticity of the arteries, sometimes referred to as hardening of the arteries.
RELATED TERMS--------------------------------------
Arteriosclerosis
Commonly called "hardening of the arteries;" a variety of conditions caused by fatty or calcium deposits in the artery walls causing them to thicken.
Atherosclerosis
Also known as arteriosclerosis, atherosclerosis results from the accumulation of cholesterol-laden plaque in artery walls. Plaque accumulation causes a narrowing and a loss of elasticity of the arteries, sometimes referred to as hardening of the arteries.
Plaque
Soft sticky substance that accumulates on teeth; composed of bacteria and food debris due to inadequate dental hygiene.
Artery
A blood vessel that carries blood from the heart to the body.
Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.
SIMILAR TERMS--------------------------------------
Athelia
Absence of the nipple. Athelia is a rare condition but it is common in certain conditions. Athelia tends to occurs on one side (unilaterally) in children with the Poland sequence and on both sides (bilaterally) in certain types of ectodermal dysplasia.
Athens Regional Medical Center
Athens Regional Medical Center is a hospital in Athens, Tennessee (USA).
Atherectomy
A non-surgical procedure that involves removing plaque from the walls of arteries with a rotating blade.
Atherectomy (Directional Coronary Atherectomy or DCA)
The DCA catheter has a hollow cylinder on the tip with an open window on one side and a balloon on the other. When the catheter is inserted into the narrowed artery, the balloon is inflated, pushing the window against the fatty matter clogging the vessel. A blade (cutter) within the cylinder rotates and shaves off any fat, which protruded into the window. The shavings are caught in a chamber within the catheter and removed. This process is repeated as needed to allow better blood flow.
Atherogenesis
The process of forming atheromas, plaques in the inner lining (the intima) of arteries.
Atheroma
A fatty deposit in the intima (inner lining) of an artery, resulting from atherosclerosis. Also called an atherosclerotic plaque, arterial plaque or, simply, a plaque.
Atheroma:
Large build-up of fat, cholesterol and other substances on the walls of an artery, causing narrowing. Also called plaque.
Atherosclerotic
Pertaining to atherosclerosis, the process of progressive thickening and hardening of the walls of arteries from fat deposits on their inner lining.
Atherosclerotic aneurysm
The most common type of aneurysm, affecting the abdominal portion of the aorta and other large arteries, particularly with age.
Athetosis
Slow, involuntary movements of the hands and feet.
PREVIOUS AND NEXT TERMS--------------------------------------
Anal cancer
Colorectal cancer includes cancerous growths in the colon, rectum and appendix.It is the third most common form of cancer and the second leading cause of death among cancers in the Western world. Many colorectal cancers are thought to arise from polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time. Diagnosis is by colonoscopy. Therapy is usually through surgery, with many cases also requiring chemotherapy.
Angina
A recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood. It is a common symptom of coronary heart disease, which occurs when vessels that carry blood to the heart become narrowed and blocked due to atherosclerosis. Angina feels like a pressing or squeezing pain, usually in the chest under the breast bone, but sometimes in the shoulders, arms, neck, jaws, or back. Angina is usually is brought on by exertion, and relieved within a few minutes by resting or by taking prescribed angina medicine. Commonly called chest pain, heart pain or angina pectoris.
Astrocytoma
A nervous system tumor that grows from astrocytes (astrocytomas are a type of glial cell, glial cells are the supporting cells of the nervous system). They can occur in children and young adults and sometimes in older people. Astrocytomas can sometimes become large before causing symptoms. A diagnosis is made either after surgical resection or with a guided (stereotactic) biopsy. Treatment can consist of surgical excision, radiation therapy or chemotherapy. Some patients with minimal symptoms may be observed with serial imaging studies.
Abscesses
A collection of pus collected in a cavity formed by the tissue on the basis of an infectious process (usually caused by bacteria or parasites) or other foreign materials (bullet wounds etc). It is a defensive reaction of the tissue to prevent the spread of infectious materials to the other parts of the body.
Arthritis
Inflammation of a joint, usually accompanied by pain, swelling, and stiffness, and resulting from infection, trauma, degenerative changes, metabolic disturbances, or other causes. Arthritis occurs in various forms, such as the arthritis associated with infections, osteoarthritis, or rheumatoid arthritis. Many forms of vasculitis can also be associated with arthritis.
Atherosclerosis
Allergy
A major defense mounted by the body's immune system against normally harmless substances, or allergens, such as chemicals in pollen, food, bee stings, animal dander, or dust. An allergic reaction is the body's strong reaction to these substances in a person who is sensitive to them. Reactions range from mild to severe, and may include sneezing, a rash, or difficulty breathing (which can be fatal).
Amputation
Amputation is the removal of a body extremity by trauma or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene.
Ataxia
Ataxia is unsteady and clumsy motion of the limbs or trunk due to a failure of the fine coordination of muscle movements. The cerebellum is the center of the fine coordination of muscle movements, while the information emerging from it is carried to the muscles by the spinal cord and peripheral nerves, respectively. Therefore a disorder in either the spinal cord or in the peripheral nerves can cause ataxia.
ADHD
Attention-deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed and controversial mental disorders among children, and is increasingly recognized as afflicting adults as well. Its symptoms include inattention, hyperactivity, and impulsivity.
Autism
A neurological developmental disability that results in limited cognitive abilities: the autistic individual is limited in ability to learn inductively from surrounding events. Social interactions and many kinds of conceptual learning can be strongly limited. At the same time, the autistic individual may be outstandingly good at some kinds of mental manipulations, such as, for example, arithmetical calculations.
