Atheroma

thickening in the arterial wall called an Atheroma (or "fibro-fatty plaque"). Atheroma narrows the lumen of arteries and weakens the vessel wall. Atherosclerosis begins in childhood and slowly progresses throughout life. Typically, it produces symptomatic clinical disease during the fifth and sixth decades of life. The atheromatous plaque is a raised lesion within the intima of arteries composed of a core of cholesterol, necrotic cellular debris and inflammatory cells. This is covered by a "cap" of smooth muscle cells and collagen fibers.(Back et al, 2003) • Endothelial Injury: Chronic endothelial injury is the initial step in the development of atherosclerosis. Hemodynamic stresses such as turbulence at points of narrowing and branching…

QUESTIONS 1. Discuss the pathophysiology of coronary artery atherosclerosis. Include discussion of risk factors associated with the development of this disease. (10 points) Coronary artery atherosclerosis is most commonly comprised of atherosclerotic fibrous fatty obstructions of the large epicardial vessels, which provide for blood flow and transport nutrients, oxygen, and elimination of metabolic waste products such as CO2, lactic acid, and hydrogen ions. Coronary artery atherosclerosis…

Introduction: What is Coronary Heart Disease? With cardiovascular diseases being the number one cause of deaths around the world, understanding the diseases, their risks and possible preventative actions can help an individual protect himself from the diseases. The research presented in this paper will focus on providing knowledge about coronary heart disease. Coronary heart disease, the most common of cardiovascular diseases, takes place when the coronary arteries become clogged with fatty…

While we see a person suffering from heart attack on screens, there is still a big difference when we see it happening on an actual event. Though many people know what heart attack is, there are only few who deeply know and understand what it is all about. As a matter of fact, heart attack is not only heart attack. There are different types of heart attacks that can happen to anyone, including you. These types of heart attacks are best determined by diagnostic tools which your doctor will need…

Mechanism Atherogenesis is the developmental process of athermanous plaques. It is characterized by a remodeling of arteries leading to sub endothelial accumulation of fatty substances called plaques. The buildup of an athermanous plaque is a slow process, developed over a period of several years through a complex series of cellular events occurring within the arterial wall and in response to a variety of local vascular circulating factors. One recent hypothesis , leukocyte, such as momocyte or…

Coronary Artery Bypass Coronary Artery Bypass is a type of procedure that improves the blood flow to the heart. Surgeons will perform Coronary Artery Bypass of patients who have been diagnosed with coronary heart disease. The disease know as coronary heart disease is known as when a waxy substance known as plaque buildup inside the coronary arteries this occurs in the arterys which supply your heart with oxeye not rich blood in time the blood can become thickend and harden which can very easily…

The towering causes and effects of heart disease surround us in our everyday lives. Everybody, at some point, is being exposed to a risk factor or something that further longs the chances of getting heart disease. What is heart disease? "Look into proposes that coronary illness (CHD) starts with harm to the covering and inward layers of the coronary (heart) supply routes." A few components add to this harm. The risk factors that cause heart disease are mostly composed of everyday problems that…

Myocardial Infarction (MI) commonly known as heart attack occur when blood supply is interrupted, causing damage or death of the heart cells. What causes the heart muscle to lose its blood supply? Usually, the loss of the heart's blood supply is caused by the total blockage of a coronary artery by a blood clot on a cholesterol plaque in the artery. Cholesterol is a fatty chemical which is a part of the outer lining of cells in the body. Cholesterol plaque is the formation of a hard substance…

What is Cardiac Catheterization? It is a procedure to examine how well your heart is working. A cardiologist places a thin, hollow tube (sheath) into an artery that leads to the patient’s heart. This will allow guide wires and catheters to be used. A contrast dye is injected through the catheter that can be seen on x-rays. This shows how the blood is flowing to the heart and any blockages or deformities. During the catheterization, the physician can attempt stent or balloon any narrowings that…

Introduction ‘I will have the steak, and a side of mac & cheese.’ While the aforementioned foods seem delicious, are they good for us? What are such delicious foods doing to the inside of ones body, and most importantly, what are such foods doing to one 's cholesterol? In moderation a person can eat delicious and tasty foods; but, when the consumption of food (high in cholesterol) becomes excessive and more than the body can handle a problem begins: high cholesterol. Pathology So what is…
