Atherosclerosis

In atherosclerosis, fatty deposits called plaque, build up on the inner wall of the coronary arteries. These fatty deposits usually develop over many years. Plaque is composed of porridge like accumulation of cholesterol and their compounds within a fibrous coat. After it builds up, the injury to the arteries signal the immune system to release white blood cells to the site. This initiates a process called the inflammatory response. Macrophages literally "eat" the oxidized cholesterol…

Heart disease is a broad term used to describe any cardiovascular disease or condition that affects the cardiovascular system. According to the Centers for Disease Control and Prevention (CDC), 47% of all Americans have at least one of the risk factors for heart disease and many don 't know it. Understanding heart disease is crucial to its prevention, however, so it 's important for you to know the causes and symptoms of heart disease. You should strive to prevent heart disease if you can and…

are caused by human nature or probability. One of the many diseases that affect people is heart disease. Heart disease can strike anyone at anytime. The history of heart disease dates back to the Egyptian mummies. Pharaoh Merenptah died from atherosclerosis, which is a type of heart disease. Some early discoveries were made by Leonardo da Vinci and William Harvey dating back to the late 1500’s and the middle 1600’s. Heart disease is the number one killer of men and women in the United States…

non-invasive way to detect coronary ischemia, and for physicians to make a quick and accurate diagnosis. (Premier Heart, 2014) Electron Beam Tomography, however, may be used to produce a better image of the heart and correlate the severity of atherosclerosis in asymptomatic patients creating a calcium volume score. (The Mount Sinai Hospital, 2014) Complications that can result from CAD can cause heart failure, ventricular arrhythmia, which may lead to ventricular fibrillation, heart attack, and…

arteries leading to our brain. If the arteries to our brain are only partially blocked, you can experience a transient ischemic attack- kind of like mini stroke. Its a brief, temporary disruption of blood to your brain caused by a blood clot or atherosclerosis. A stroke is a longer disruption of blood flow to our brain. Oxygen and nutrient are stooped from entering our brain, causing brain cells to die. Excess sodium leads to high blood pressure, which can cause a stroke by weakening the blood…

ILLINOIS EASTERN COMMUNITY COLLEGES, DISTRICT #529 OLNEY CENTRAL COLLEGE ASSOCIATE DEGREE NURSING PROGRAM FCC-LTC-OCC-WCC NURSING 1201 TEXTBOOK DATA CEREBRAL INFARCTION Definition: Cerebral infarction is commonly known as ischemic stroke. Ischemic stroke occurs when blood supply to the brain is blocked. Permanent damage to brain tissue occurs at the site due to cell death at the affected area. Certain parts of the brain control different body functions, so when damage occurs this alters how…

Coronary Heart Disease Coronary heart disease (CHD) is the most common type of heart diseases. According to the CDC, coronary heart disease kills more than 370,000 people every year.1 Coronary heart disease results from the damage of the coronary arteries, which supply the heart with nutrients and oxygen. Coronary heart disease causes plaque formation in the coronary arteries narrowing the arteries and decreasing blood flow to the heart. Eventually, heart attack results from the complete…

cholesterol and coronary heart disease is when too much blood cholesterol build up in the artery wall causing narrowing of the artery causing too much blood cholesterol to build up in the artery wall causing narrowing of the artery also known as Atherosclerosis. Narrowing of the artery and too much cholesterol in the body is normally the cause of stroke, heart attack, and peripheral vascular disease and may cause even death. Risk factors for some individuals are smokers, diabetes, hypertension,…

Hypertension and Leptin The cumulative effect of Leptin administered for short term on blood pressure in the conditions of a healthy subject are negligible. The sympathetic activity of the nervous system is activated by Leptin in lean animals (Peckett, Wright, & Riddell, 2011). However, a balance is created by the vasorelaxation that is NO-dependent and natriuresis in the event which the blood pressure is kept constant. However, prolonged hyperleptinaemia leads to an increase in the blood…
