Atherosclerosis Research Paper

Atherosclerosis (ath"er-o-skleh-RO'sis) comes from the Greek words athero (meaning gruel or paste) and sclerosis (hardness). It's the name of the process in which deposits of fatty substances, cholesterol, cellular waste products, calcium and other substances build up in the inner lining of an artery. This buildup is called plaque. It usually affects large and medium-sized arteries. Some

While most people have heard of strokes, many don't know the importance of your carotid artery in causing a stroke. It's important for everyone to understand the signs of carotid artery disease and how to reduce the risk of it leading to a stroke.

This slow process of disease may begin in childhood. In some people, the disease can cause symptoms between 30 and 40 years of age, while others have no symptoms until after 50 or 60 years. But it increases the degree of obstruction, the reduced flow of blood to the heart can begin to cause what is known as angina pectoris.

Atherosclerosis can be a serious condition; it is when the arteries become clogged by fatty substances such as plaques or atheroma. This causes arteries to become narrow and harden which can restrict blood flow preventing organs from functioning properly (Williams 2000).

Coronary artery disease Coronary arteries are blood vessels that carry blood to the heart muscle. The coronary artery disease (also called CAD, for its acronym in English) or coronary heart disease is caused by a thickening of the inner walls of the coronary arteries. This thickening is called atherosclerosis. A fatty substance called plaque builds up inside the thickened walls of the arteries and obstructs or delays the flow of blood. If the heart muscle does not receive enough blood to function properly, you may have angina or a heart attack.

Heart disease causes almost thirty percent of elderly death each year and caused twenty-five percent of all deaths in 2008 (cardiosmart), yet despite its high death rates, we often are not taught the preventative measures before it is too late. While some risk factors of cardiovascular disease are uncontrollable (such as genetics, race, and age) many can be reduced through lifestyle changes. It is important to understand the risk factors, prevention methods, and types of cardiovascular disease.

Atherosclerosis is the hardening and narrowing of arteries, which quietly and gradually blocks arteries, putting blood flow at risk, according to WebMD. Plaque gathers up in the arteries and is composed of fatty substances, calcium, fibrin, cholesterol, and waste products from cells. It can completely or partly cut off the blood in the artery. One of two things can happen in the area where the plaque is building up in the artery: a piece of the plaque may break off or a blood clot may form on the plaque's surface, according to the American Heart Association. Atherosclerosis is a kind of arteriosclerosis, which is simply the thickening and hardening of arteries. It is typically the agent of strokes, peripheral vascular disease, and heart attacks,

Every day there are news stories that pop up about new deadly diseases that ravish the world. But who knew that one of the deadliest diseases is also one of the most common. This disease is called Coronary Artery Disease (CAD), which is a form of heart disease. Affecting more than 15 million Americans, this is also the leading cause of death in the United States (Texas Heart Institute). Several things can attribute to this. Some of the main factors are pre-existing illness, lifestyle choices, and hereditary factors.

Atherosclerosis is a reduction of the arteries triggered by a buildup of plaque. It is also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that transport oxygen and nutrients from the heart to the rest of the body. As the body gets older, fat and cholesterol can collect in the arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through the arteries. This buildup may transpire in any artery in the body and can result in a shortage of blood and oxygen in various tissues of the body. Pieces of plaque can also break off, causing a blood clot. If left untreated, atherosclerosis can lead to heart attack, stroke, and heart failure. Atherosclerosis is a fairly common problem associated with aging. According to the University of Maryland

Atherosclerosis is a disease in which fatty materials and plaque buildup on the inner lining of arteries. Arteries are blood vessels which carry rich blood to the heart and throughout the body. They’re lined by the endothelium, a thin layer of cells. The endothelium keeps blood flowing by keeping the inside of arteries smooth. However, when Atherosclerosis starts due to high blood pressure, smoking, or high cholesterol, it damages the endothelium. Atherosclerosis tends to happen throughout the body and arises when people grow older. This disease is mainly due to the deposition of fatty materials i.e., cholesterol, calcium and other substances found in the blood. The buildup of fat then hardens causing narrowing of the arteries. This

The current epidemic of coronary heart diseases continues to increase as “cardiovascular disease (CVD) is the leading cause of death globally resulting in about 30% of deaths annually” (Jaleta, Gudina, & Getinet, 2014) and with Atherosclerosis being one of the top diseases among African Americans and obese children. Atherosclerosis is described as the disease of clogged arteries from buildup of plaque, causing arteries to become narrow, thick, and stiff which makes blood flow very difficult to pass. As many factors do contribute to the growth of this disease, this literature review will discuss the factors of the African American race as well as children being affected by Atherosclerosis. The substances of the plaque is usually composed of cholesterol, fat, and calcium which sticks together to harden over time in the walls of the arteries. As a result of such action, narrowed arteries can cause blood clots which can overtime lead to a heart attack. Although it is a treatable condition, lots of preventable methods are required to see improvements such as nutrition and exercise.

One source of great mortality and morbidity in Europe and North America is the cardiovascular disease, Atherosclerosis. It is recognized as a chronic inflammatory disease of the intermediate and large arteries characterized by the thickening of the arterial wall and is the primary cause of coronary and cerebrovascular heart disease (Wilson, 2005). It accounts for 4.35 million deaths in Europe and 35% death in the UK each year. Mortality rate are generally higher in men than pre-menopausal woman. Past the menopause, a woman’s risk is similar to a man’s (George and Johnston, 2010). Clinical trials have confirmed that lipid accumulation, endothelial dysfunction, cell proliferation, inflammation matrix alteration and foam cell formation are

Lesions on the arterial wall can cause them to become weak and get into the high risk area of dilatation and rupture. Atherosclerotic aneurysm is a disease of elderly persons, rare before age 50. Its frequency peak is around age of 70 years. It can be seen in different shapes, fusiform, saccular and cylindrical. The cause is usually atheroma expansion in the

An inherited killer, Cardiovascular diseases are quite devastating. From medical bills to lost sleep cardiovascular disease can destroy many families. In today's world, there is a rise in the US population adopting unhealthy lifestyles that lead to cardiovascular disease. Cardiovascular diseases are also known as heart diseases. This is a class of diseases that affect the heart and the blood vessels. The blood vessels are the arteries, capillaries, and the veins. The various diseases that fall under the term cardiovascular disease include coronary artery disease, heart attack, heart failure, high blood pressure and stroke. The more common form of cardiovascular disease is Coronary Heart Disease or Coronary Artery Disease. The Coronary Artery

Atherosclerosis begins with damage to the inner wall of an artery. Substances in the body such as cholesterol, fats and cellular waste products accumulate inside the damaged area. Chemical reactions occurring within the build-up of these waste products cause cholesterol molecules to oxidize. This initiates an inflammatory response within the body in which the endothelial cells release chemicals. These chemicals are toxic to the body, signaling a call for help. In response to this chemical reaction, monoxides from the bloodstream travel to the affected site. Stimulation from the oxidized cholesterol turns the monoxides into macrophages. As a result, the macrophages change into foam cells, which accumulate over time to form plaque. As the plaque
