Coronary Illness In Australia Essay

Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis. Atherosclerosis is the narrowing and thickening of arteries and develops for years without causing symptoms. It can happen in any part of the body. Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease. The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack. (World Heart Federation).

Coronary artery disease (CAD) develops when plaque builds up in the narrow arteries of the heart. The arteries that are affected supply blood to your heart, oxygen, and numerous amounts of nutrients to the heart. The plaque that builds in the arteries is from the amount of cholesterol that is accumulated in the arteries. The plaque that builds within the arteries of the heart decrease the blood flow to the heart often resulting in chest pain (angina), shortness of breath, or other symptoms. This disease is often not diagnosed until the patient has a heart attack. The reason that coronary artery disease goes unnoticed is because this disease develops over decades. “Heart disease is the leading cause of

Atherosclerosis is the process in which substances known as plaques, which are made up of cholesterol and platelets, adhere to tears in the walls of arteries. Over time these plaques build up to the point where they occlude blood flow in the arteries. When this happens in the coronary arteries, either directly, as the result of buildup in the arteries themselves, indirectly in the form a clot from another part of the body breaking loose and becoming lodged in the coronary arteries, the usual result is a heart attack.3

In blocked or obstructed arteries, blocked coronary artery blood flow may be resulted by the deposition of cholesterol, calcium and some fatty substances referred to as plaque. The deposition process begins at early ages and when growing at a different rate in every individual regarding the presence of the risk factors. These deposits accumulate gradually eventually reducing the diameter of the coronary artery to the extent that blood vessels can no longer pass blood to the need of muscles of the heart. Apart from the clogging plaque, there exist other mechanisms that may also contribute to the reduction of blood flow to the heart. These include spasm of the coronary artery and also

Nevertheless, there is an understandable and noticeable link between circulatory related diseases and lifestyle diseases, such as Coronary Heart Disease. Coronary heart disease can occur when fatty acids, such as cholesterol in an inadequate diet, build up in the walls of the coronary artery. These fatty deposits collect minerals and harden to become a plaque. Eventually, this plaque grows and can swells up, forming an aneurism. In some cases, this aneurism may burst leading to instant death. As it continues to grow and swell up, it finally blocks the artery completely and forms blood clots. This is known as coronary thrombosis. A myocardial infarction, or in other words as heart attack, occurs when no oxygen is able to reach the coronary artery and thus it is unable to fulfil its role in providing the heart muscle with a sufficient supply of blood. Heart attacks are very common in the society nowadays, especially occurring in smokers or obesity related diseases (Millar, June 2014)

Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)

Atherosclerosis is a disease affecting the innermost layer of large and medium sized such as aorta and coronary arteries. It is a slow developing disease, it is complex and often starts in childhood and progresses with increasing age (Miksch, Hunter, & Papailiou, 2005). It appears as focal thickenings called fibrofatty plaques in an artery wall, these plaques are

Artery coronariasLa artery disease coronary (EAC) affects more than 15 million Americans, being both the most common type of cardiovascular disease. The EAC and its complications, such as arrhythmia, angina pectoris and heart attack, are the main causes of death in the United States. The most frequent cause of EAC is a disease known as 'atherosclerosis' that occurs when forms a waxy substance within the arteries that irrigate the heart. This substance, called «plate», is composed of cholesterol, fatty, calcium and a coagulant substance called «fibrin». Identified two types of plate: plate hard and soft plate.

After time of accumulation and build up the plaque it becomes hardened plaque, and the hardened plaque makes the coronary arteries narrower, which lead to reduce the blood flow to the heart muscles.

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.

Atherosclerosis, the underlying cause of coronary heart disease which can affect any artery in the body, is essentially the narrowing of arteries due to excessive build up of cholesterol-rich lipids known as plaque (Insull 2009). Once the arteries become narrow, the flow of blood will be constricted, and the amount of blood, nutrients and oxygen that are able to reach the heart are reduced. As a consequence, the heart becomes increasingly hypoxic resulting in ineffective contraction. The aftermath of narrow arteries often poses serious consequences as it has a high probability of causing heart attack, angina, or even stroke (Marieb & Hoehn 2010; Insull 2009). Despite the fact that arteries will harden naturally as people age, the rate of plaque development is determined by the number of risk factors (Insull 2009). This essay will discuss and review the procedure in which the risk factors: hypertension, abnormal level of blood lipids, and smoking took to assist in the development of atherosclerosis.

With the increased consumption of fast-food and poor lifestyle choices, we have become an increasingly obese nation. For this reason, diseases such as cardiovascular disease have been on the rise. Cardiovascular disease is the combined term for a number of diseases concerning the heart and the blood vessels. Many of these life threatening diseases are related to a condition called atherosclerosis. The condition creates plaque build-up on the walls of the blood vessels. The plaque effects the flow of blood making it harder and can lead to blood clots which stops the flow of blood altogether. The two main effects to this are heart attacks and strokes however, other types of cardiovascular disease includes complete heart failure, arrhythmia

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

Arteries carry blood from the heart to the rest of the body. A thin layer of cells allows blood to flow easily and it’s called the endothelium. Atherosclerosis begins when the endothelium becomes damaged allowing bad cholesterol to build up in the artery wall. The body sends white blood cells to clean up the bad cholesterol but sometimes the cells get stuck at the affected site. Over time plaque can accumulate, made up of cholesterol, macrophages, calcium, and other substances from the blood. Can be fatal if not treated.

Today, cardiovascular disease and hypertension are two of the leading non-communicable in society. Heart disease occurs due to an overgrowth of plaque in the arterial walls circulating
