Atherosclerosis: The causes‚ consequences‚ and remedy. 03/18/2013 Biol 2401-C04 Md Ismail Hossain Indroduction Atherosclerosis: After cancer‚ heart disease is the second cause of death in the world. One of the prominent causes of heart disease is atherosclerosis. In general‚ atherosclerosis means the narrowing of blood vessel which ultimately hinders the blood flow through the vessel. Various substances accumulate on the inner wall of blood vessel and with time the blood vessel start to lose

Background Atherosclerotic plaques that result in acute coronary syndromes often occur at sites with coronary artery stenosis. The risk factors for developing these plaques and events at this point poorly understood. Methods In a prospective study‚ 697 patients with acute coronary syndromes underwent three-vessel coronary angiography and gray-scale and radiofrequency intravascular ultrasonographic imaging after percutaneous coronary intervention. Subsequent major adverse cardiovascular

1. Atherosclerosis is a disease of large and medium-sized muscular arteries Characteristics: endothelial dysfunction vascular inflammation buildup of lipids‚ cholesterol‚ calcium and cellular debris within the intima of the blood vessel wall. The build up results in atheroma (plaque formation). It is a fatty deposit in the intima of an artery‚ resulting from atherosclerosis. Atheroma/Plaque is made up of: fatty substances Cholesterol Waste products from cells Calcium

Pathophysiology of Coronary Artery Disease Atherosclerosis is a type of arteriosclerosis caused by a build-up of plaque in the inner lining of an artery. (Arteriosclerosis is a general term for thickening or hardening of the arteries.) (Porth 2005) Plaque is made up of deposits of fatty substances‚ cholesterol‚ cellular waste products‚ calcium‚ and fibrin‚ and can develop in medium or large arteries. The artery wall becomes thickened and looses its elasticity. (Fraser 2000) The wall of an artery

The Disease Process of Atherosclerosis & its Complication; Myocardial infarction Loretta Zambito McMaster University HTH SCI 2C06 Dr. Ruth Hannon March 11‚ 2013 Atherosclerosis is the primary topic for this research paper. It is a disease process that can lead to many complications‚ one of which is called myocardial infarction; otherwise known as a heart attack. Atherosclerosis‚ or the hardening of the arteries‚ is defined as a disease characterized by abnormal thickening of the

Atherosclerosis Michael Oliveira BS-104-A&P II-MW1 12/01/2012 According to the National Heart Lung and Blood Institute‚ Atherosclerosis is a disease in which plaque builds up mainly inside the medium to large elastic and muscular arteries that carry oxygenated blood to the heart and other areas of the body. Over time‚ plaque‚ made up of fat‚ cholesterol‚ calcium‚ and other substances‚ hardens and narrows the arteries limiting the flow of oxygen to organs and other parts of the body. This

The risk factors related with atherosclerosis can be classified as modifiable and non-modifiable. It is essential to recognize the difference between the two since treatment can be used to hinder the modifiable variables. Non-modifiable risk factors include: age‚ gender‚ race or ethnicity‚ and family history. The physiologic changes related with age add to the advancement of atherosclerosis and CVD in adults. As an individual ages‚ the veins and arteries become less flexible and the walls of the

Atherosclerosis: Vascular Disease Development and Progression Atherosclerosis is a chronic inflammatory disease occurring in the arterial wall over many decades and is characterized by lesion formation and luminal narrowing of the arteries. Atherosclerosis is the most common disease of modern times. In symptomatical situations‚ arteriosclerosis can be obvious like coronary heart disease‚ myocardial infarction‚ peripheral arterial occlusion disease. The disease caused by narrowing of the artery and

certain types of cancer‚ and sedentary lifestyle. Once the intimal layer of coronary artery is damaged‚ fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of these plaques breaks or ruptures‚ platelets will clump at the site to try to repair the artery. This clump can block the artery‚ leading to a heart attack. Recent research has

INTRODUCTION Cardiovascular disease‚ currently the leading cause of death and illness in the United States‚ Europe and most developed countries‚ is fast growing to become the preeminent health problem worldwide (Murray & Lopez‚ 1997). Atherosclerosis is a progressive disease of the large and intermediate-sized arteries characterized by accumulation of lipids and fibrous elements which cause development of fatty lesions called atheromatous plaques on the inside surfaces of the arterial walls;
