Coronary Artery Disease ( Cad )

Coronary artery disease (CAD) develops when plaque builds up in the narrow arteries of the heart. The arteries that are affected supply blood to your heart, oxygen, and numerous amounts of nutrients to the heart. The plaque that builds in the arteries is from the amount of cholesterol that is accumulated in the arteries. The plaque that builds within the arteries of the heart decrease the blood flow to the heart often resulting in chest pain (angina), shortness of breath, or other symptoms. This disease is often not diagnosed until the patient has a heart attack. The reason that coronary artery disease goes unnoticed is because this disease develops over decades. “Heart disease is the leading cause of

Coronary artery disease remains number one killer of the western civilization despite 40 years of aggressive drug and surgical interventions (Esselstyn). Usually, pharmaceutical drugs, such as statin, are given to try to slow the progression, but may provide uncomfortable side effects. In fact, the majority of patients discontinue statins within 1 year of treatment initiation (Maningat). Furthermore, surgery is performed to circumvent clogged arteries and literally bypass the symptoms. In the last year, 500,000 coronary bypass procedures were performed (Swaminathan et al). However, these surgeries can have significant risks, including the potential to cause further heart damage, stroke, and brain dysfunction. Thus, it is evident that these way of treatments may not be enough on its own, and that getting to the

A sufficient coronary artery blood flow is essential to supply oxygen for normal cardiac activities (Craft, 2014, p. 599). Atherosclerosis is a common form of CHD. It is an inflammation disease when plasma cholesterol is high. Risk factors such as hypertension, high cholesterol, smoking and diabetes increase the risk of endothelium injuries, contributing to the increase in oxidated lipid-lipoprotein (LDL). Foam cell is produced by the increase in the number of macrophages signalled by oxidated LDL. Next, the accumulation of foam cells will cause the formation of fatty streak lesions on arteries walls. Over time, fatty streak lesions migrate to the site and form fibrous plaque due to the increase in smooth muscles and collagen. The thickening and hardening initiated by an accumulation in calcified fibrous plaque caused the blood vessels to narrow. As a result, a decrease in tissue perfusion contributing to the development of myocardial ischemia (Craft, 2014, p. 599; McCance & Huether, 2014, pp. 1145-1147).

Coronary heart disease (CHD), also known as ischemic heart disease is the most prevalent form of cardiovascular disease in Australia (Australian Institute of Health and Welfare, 2014). While over 20,000 of deaths in 2011 were attributed to CHD. There were estimated 590,000 Australians 18 years old and above diagnosed with CHD in 2011-2012 (AIHW, 2014; Craft, 2014, pg. 596). Myocardial ischaemia is a common form of CHD. A sufficient coronary artery blood flow is essential to supply oxygen for normal cardiac activities. Myocardial ischaemia develops when there is an insufficient supply of blood and oxygen to support the function of myocardial cells (Craft, 2014, pg. 599). A decrease in blood supply can led to the formation of atherosclerotic plaques by narrowing or occluding the arteries. Other conditions such as hypotension, coronary spasm, dysthymias, hypoxemia and anaemia can also decrease the blood and oxygen supply to the myocardial cells (McCance & Huether, 2014, pg. 1153)

Artery coronariasLa artery disease coronary (EAC) affects more than 15 million Americans, being both the most common type of cardiovascular disease. The EAC and its complications, such as arrhythmia, angina pectoris and heart attack, are the main causes of death in the United States. The most frequent cause of EAC is a disease known as 'atherosclerosis' that occurs when forms a waxy substance within the arteries that irrigate the heart. This substance, called «plate», is composed of cholesterol, fatty, calcium and a coagulant substance called «fibrin». Identified two types of plate: plate hard and soft plate.

Coronary artery disease (CAD), also known as coronary heart disease, is the leading cause of mortality in both men and women in the United States today. It has been reported by the Centers for Disease Control and Prevention that CAD accounted for nearly 616,000 deaths in 2011 and was responsible for 1 in 4 deaths in the U.S. in the same year. 1 Coronary artery disease is a progressive disease where the major arterial vessels supplying the heart become occluded and sclerotic due to the buildup of plaque in the inner walls of the artery through a process called atherosclerosis. 2 CAD eventually leads to heart failure and a myocardial infarction (MI).

Coronary artery disease Coronary arteries are blood vessels that carry blood to the heart muscle. The coronary artery disease (also called CAD, for its acronym in English) or coronary heart disease is caused by a thickening of the inner walls of the coronary arteries. This thickening is called atherosclerosis. A fatty substance called plaque builds up inside the thickened walls of the arteries and obstructs or delays the flow of blood. If the heart muscle does not receive enough blood to function properly, you may have angina or a heart attack.

With the increased consumption of fast-food and poor lifestyle choices, we have become an increasingly obese nation. For this reason, diseases such as cardiovascular disease have been on the rise. Cardiovascular disease is the combined term for a number of diseases concerning the heart and the blood vessels. Many of these life threatening diseases are related to a condition called atherosclerosis. The condition creates plaque build-up on the walls of the blood vessels. The plaque effects the flow of blood making it harder and can lead to blood clots which stops the flow of blood altogether. The two main effects to this are heart attacks and strokes however, other types of cardiovascular disease includes complete heart failure, arrhythmia

Some risks for CAD could be smoking, HTN, obesity, bad cholesterol, diabetes, and genetics. There are so many risk factors for CAD, but most of them can be lowered by changing one’s lifestyle. Usually, up till the age of 70, males may have a higher chance for CAD.

Atherosclerosis is almost worldwide. Although it is hard to estimate how common atherosclerosis is, almost all adults have various parts of the illness. Cardiovascular disease is the single most common cause of illness and death in the developed country accounting for one in three of all deaths! Heart attacks due to coronary artery disease and strokes due to carotid artery disease are responsible for more deaths than all other causes combined. According to statics more than 80,000 people with cardiovascular disease died in 2005, making it the No.1 killer in America. Not only that, but each year in England and Wales, an estimated 124,000 deaths are caused by CVD, where about 39,000 of them occur in people under the age of 75. Due to the continuing obesity prevalent, it is predicted that atherosclerosis will continue to be a major health problem in this country.

First, Coronary Artery Disease is a serious heart condition that impairs blood flow to the heart muscle. A nurse should have knowledge of the disease process, signs and symptoms, diagnostic tests, and treatments available. The coronary arteries supply blood, oxygen, and nutrients to the heart. The main coronary arteries are the left and the right arteries. The left coronary artery. The disease is typically caused by plaque accumulation in the coronary arteries. Atherosclerosis is the formation of plaque affecting layers of the large and midsize arteries. Plaque contains cholesterol, triglycerides, phospholipids, and collagen. When plaque accumulates in the arteries it decreases the size of the inside of the arteries. Plaque may surround the

Coronary heart disease (CHD) is a common cardiovascular disease that occurs when the coronary arteries supplying blood to the heart muscles are narrowed or blocked by fatty materials build-up over time. There are 2 forms of coronary heart disease, angina and myocardial infarction. CHD results in 70,000 deaths each year, making it the single biggest cause of death in the UK. More than 2.3 million people are currently living with CHD (British Heart Foundation, 2014). CHD has always been wrongly perceived as a man’s disease due to the fact that men more than women have a higher rate of obesity, smoking, alcohol consumption and other cardiovascular diseases that put them under the risk of developing CHD (Barrett-Connor, 1997). However, social determinants, such as socioeconomic position, employment status and family demand can have significant impact on women’s health profile despite the fact that they seem to be protected from CHD biologically by oestrogen (EDMUNDS, 2000). Sir Donald Acheson mentioned in his Independent Inquiry into Inequality in Health Report that “Health inequalities are the outcome of causal chains which run back into and from the basic structure of society”(Acheson, 1998). Employment and family structure being the most basic, however essential components of the human society can affect women’s physical health and shape their psychological characteristics to a great extent. This essay aims to compare the differences of employment and family structure of

Obstruction is the action of obstructing or the state of being obstructed. An obstruction disease is a disease that impedes or prevents passage or progress of blood through the veins or arteries inthe body. Coronary artery disease, also known as atherosclerotic heart disease, is damage or disease to heart's major blood vessels, the arteries. Coronary artery disease is usually caused by a buildup of plaque. This buildup of plaque causes the arteries to become narrow and harder, which limits blood flow to the heart. People that get coronary artery disease can be asymptomatic and not experience any symptoms. But people may experience chest pain, indigestion or nausea, light headness, or sweating, fast heart rate or shortness of breath. CAD has

Heart disease, also known as the “silent killer”, is one of the most common causes of death worldwide, though many people live with this disease for many years without knowing it. Types of heart diseases include coronary artery disease, cardiomyopath, valvular heart disease, pericardial disease, and congenital heart disease. The most common type of heart disease is coronary artery disease.

CAD may further lead to other forms of heart diseases like heart attack, heart failure, and arrhythmia. Depending on the severity of the disease, people suffering from CAD may benefit from Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Grafting (CABG). PCI, commonly known as angioplasty is a minimally invasive procedure used to open blocked blood vessels; while
