Atherosclerosis

Disease of the arteries called atherosclerosis is medical condition characterized with accumulation of fatty material on the internal walls of the blood vessels that has impact on the blood flow. Medical experts warn that this medical condition is quite severe as it may lead to cardiac arrest, brain hemorrhages or even death. Doctors explain that the bad habits significantly worsen this issue, and some of the most common mistakes are: eating a lot of fat, smoking, lack of physical activity, overweight

Atherosclerosis is a chronic disease that can beginning in childhood or adolescence. Atherosclerosis is defined as a buildup of fatty material, such as cholesterol, in the walls of blood vessels. There are three progressive states of excess fatty material in the blood vessel walls: fatty streak, intermediate lesion, and a fibrous lesion. A fatty streak is a line of yellow fatty material in the blood vessel wall, and as the streak becomes larger it is then called an intermediate lesion then a fibrous

Chapter 1 Introduction History and background Atherosclerosis: Atherosclerosis is a type of arteriosclerosis. Arteriosclerosis is a general term for the thickening and hardening of arteries. Atherosclerosis, or hardening of the arteries, is a pathological situation in which plaque builds up inside the arteries. Plaque is usually made of cholesterol, fatty substances, cellular products, calcium and fibrin (a clotting material in the blood). Atherosclerosis is the leading cause of mortality and morbidity

Atherosclerosis is a chronic disease of the arterial wall that is characterized by the thickening of the arterial inner lining. These thickenings are often called atherosclerotic lesions or atheromas. Caused by the accumulation of cholesterol-rich lipids, lipid oxidation and inflammatory response, these atherosclerotic lesions are said to originate from fatty streaks in childhood. These fatty streaks result from an excess of lipid concentrations in the intima. Immune processes are involved in the

Introduction According to Heart foundation (2015) , coronary heart disease is a major cause of death in Australia, which kills about one Australian every 12 minutes. It is known that the development of atherosclerosis is the vital cause of coronary heart disease. It induces the accumulation of connective tissue rudiments, lipids, cells and other elements in the coronary artery wall (Hansson, 2005). This results in the asymmetric thickenings of the innermost layer, intima, which prevents adequate

Introduction Atherosclerosis is an inflammatory disease that causes formation of plaques under the intimal layer of the blood vessel wall. As the plaque grows and calcifies, it narrows the blood vessel lumen and decreases blood flow to the downstream tissue. Also, risk of plaque rupture increases. Plaque rupture leads to platelet adhesion that results in a thrombus, which occludes the artery. Occlusion of the coronary arteries results in myocardial infarction. Pathologies affecting small and medium

Atherosclerosis is the main cause of the death from heart disease. Heart is a big muscle which needs lot of oxygen. But because of a blood clot that blocks a big coronary vessel, blood cannot flow, a heart has not enough oxygen and develop necrosis. Many people continue to think of heart disease as a man’s disease. However: • Heart disease is the #1 killer of American women, but many women do not realize they are at risk • Heart diseases kill more women than breast cancer While 1 in 31 American

Atherosclerosis can be associate with atheromata’formation, which are raised, fibroadipose plaques that develop within the intimal layer of the artery or within the innermost layers of the tunica media. Some atheromata undergo calcification or ulceration, and mural thrombi can form over complicated and uncomplicated atheromata. As a result, can block or diminished the blood flow in the artery, turning tissue and organs oxygen deprived. Lesions on the arterial wall can cause them to become weak and

What are some types of heart and blood vessel diseases? HARDENING OF THE ARTERIES, or atherosclerosis, is when the inner walls of arteries become narrower due to a buildup of plaque (usually caused by a diet high in fat, cigarette smoking, diabetes or hypertension). This limits the flow of blood to the heart and brain. Sometimes, this plaque can break open. When this happens, a blood clot forms and blocks the artery. This can cause heart attacks and strokes. HIGH BLOOD PRESSURE, also called hypertension

Oxidative Stress and inflammation in Atherosclerosis: A Brief Review Abstract: Atherosclerosis is a disease in which plaque builds up inside the arteries. Arteries are blood vessels that carry oxygen-rich blood to the heart and other parts of the body. Reactive oxygen species are common by-products of many oxidative biochemical and physiological processes. They can be released by NAD(P)H oxidase, nitric oxide synthase and xanthine oxidase and activates various signaling pathways that underlie vascular
