Atheroma Essays

Coronary artery disease is usually caused by atherosclerosis. Cholesterol and other fatty substances accumulate on the inner wall of the arteries. This attracts fibrous tissue, blood components, and calcium, which harden into flow-obstructing plaques. If a blood clot suddenly forms on one of these plaques it can convert a partial obstruction to a total occlusion. When the blockage is temporary or partial, angina (chest pain or pressure) may occur. When the blockage completely and suddenly cuts off

Introduction An atherectomy is a surgical procedure to remove a buildup of fat, cholesterol, and other substances (plaque) from the inside of an artery. Arteries are the blood vessels that carry blood from the heart to the rest of the body. A buildup of plaque in the arteries can block blood flow. In this procedure, plaque is removed from an artery using a device at the end of a thin, flexible tube (catheter). A narrow tube of wire mesh (stent) may be placed in the artery to keep it from getting

1. Give three different examples of the function of blood. -Blood supplies the body with the nutrients that are essential for the body; such as the following: oxygen, glucose, and insulin. - Blood removes the waste products of metabolism, in terms of creatinine, carbon dioxide and urea. -Blood provides a defense mechanism for the white blood cell count and the antibodies. 2. Briefly, describe basic blood composition and what each component consists of. There are three formed elements of blood composition

“Oh la la la …..bebe on board??? …. Dance your way thro’ pregnancy”. Dancing & Pregnancy. “Dance ,when you’re are broken open. Dance ,if you’ve torn the bandage off. Dance in the middle of fighting. Dance in your blood, Dance when you’re perfectly free” This was said by Maulana Jalal al – Din Rumi (Rumi), a 13th century Persian poet, Islamic Jurist and theologian. When I read this quote, I was reminded of an advertisement that I came across stating “Belly dancing classes” for Pregnant women and

There are many diseases or problems that you get when you get older. Problems like chest pains and heart attacks. Diseases like coronary heart dieses, which is cause by a buildup of plague in your arteries. Now plague is a waxy substance that narrows your arteries that reduce your flow of oxygen-rich blood to reach your heart, and can cause blood clots in your arteries too. Luckily there are small expandable tubes that can treat narrowed or weakened arteries in your body called stents Now stents

foam cells, other inflammatory cells, and the natural cells of arteries accumulate. Macrophage are responsible for the plaque development. Fibrous tissue is added over the lipid­rich necrotic cores developing into the dominant lesions ­Advancing atheroma: Thin­cap fibratheroma and its rupture: this stage occur greater than 55 years of age. This fibrous cap are considered “vulnerable plaque” due to its risk to rupture causing a life threatening thrombosis. ­Complex Lesion development: many of the

CHAPTER ONE 1. Introduction 1.1 Atherosclerosis Atherosclerosis is deposition of plaques containing cholesterol and lipids on the inner most layer of the walls of large and medium –sized arteries. (Herbert, 2014) Atherosclerosis is the buildup of a waxy plaque on the inside of artery, the arteries are blood vessels that carry blood from the heart through the body, and they are lined by a thin layer of cells called the endothelium. The endothelium works to keep the inside of arteries

blood and oxygen to this part of the heart which can cause the heart muscle to die off from lack of oxygen and nutrients, if the muscle has died it will be replaced with scar tissue. Atherosclerosis is where arteries become clogged with plaques or atheroma which are cholesterol and excess fatty substances, these cause the arteries to harden and do not let the proper blood supply flow which can stop organs functioning properly. These plaques can rupture which causes a blood clot, the blood clot then

INTRODUCATION THROMOS DEFINATION Thrombosis is the making of a blood clot inside a blood vessel, stop the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets and fibrin to form a blood clot to prevent blood loss from the body. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus[1] THROMBOS COMPOSITION

Periodontal diseases:- Periodontitis is a chronic multifactorial inflammatory disorder induced by microorganisms and defined by progressive damage of the tooth supporting tissues leading to tooth loss. This is to be recognized from gingivitis which is a reversible inflammatory reaction. Periodontitis is a main public health dilemma because it is common, it decrease quality of life, it decrease chewing purpose and hurt aesthetics, and finally results in tooth loss and disability. Periodontitis starts

A Cerebrovascular accident, a brain attack, or more commonly known as a Stroke, is the most common disabling neurological disorder (Aminoff, Greenberg and Simon, 2015), which affects 1.8% of the Australian population, this is an estimated 264,900 people(Abs.gov.au, 2015) . The World Health Organisation (World Health Organisation, 2015) states that a stroke is an “interruption of the blood supply to the brain, usually because a blood vessel bursts or is blocked by a clot. This cuts off the supply
