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
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
According to the American Heart Association, cardiovascular disease or heart disease is one of the leading causes of death in America. Cardiovascular disease refers to a disease of the heart and/or blood vessels. It is also known as heart disease. The term cardiovascular disease covers many conditions and is extremely dangerous. Atherosclerosis is one of the major conditions that falls under the cardiovascular disease category. Atherosclerosis is a condition that develops when plaque, made from various substances that circulate in your blood, builds up on the walls of the arteries. The buildup narrows the arteries and makes it difficult for blood to flow through. The major risks of atherosclerosis are heart attack or stroke (American Heart Association, n.d.).
Cardiovascular disease has reportedly been the number one disease killer for men and women in the United States of America. Every one out of four deaths is caused by heart disease in the United States alone (Centers for Diseases Control and Prevention). Heart disease refers to the different types of conditions and symptoms that can affect the one’s heart and its functions to the body (Mayo Clinic). Cardiovascular/Heart disease has many causes and conditions, prevention methods and symptoms, and treatment options.
Coronary heart disease (CHD), also known as ischemic heart disease is the most prevalent form of cardiovascular disease in Australia. 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 (AIHWAustralian Institute of Health and Welfare, 2014; Craft, 2014, p. 596).
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)
One of the patient’s secondary diagnoses is atherosclerotic heart disease of native coronary artery without angina pectoris. He had a heart valve replacement in 2011. Atherosclerosis is a disease in which plaque made of fat, cholesterol, calcium, and other substances builds up inside the arteries. This is an issue because the plaque hardens over time and narrows the arteries, which then limits the flow of oxygenated blood to vital tissues. This condition can lead to heart attacks, strokes, and death. Coronary artery atherosclerosis is the single largest killer of both men and women in the United States (Boudi, 2016). The patient’s atherosclerosis is located in the coronary artery. This artery is one of two main blood vessels that branch off
Blockages cause arteries to narrow and weaken resulting in inadequate blood flow to bodily tissue, which can harm major organs that receive depleted oxygen and nutrient supplies. Plaque is surrounded by a fibrous capsule that may break with increased blood flow or narrowing arteries. Immune cells trying to repair the arterial wall may result in a blot clot that seals the area. Such repairs can cause major blockages in the coronary artery supplying the heart resulting in cardiac arrest. Blockages can occur in any region of the body including the major extremities, the heart and the brain. Restricted blood flow to the heart is known as coronary artery disease and affects the blood supply to the heart muscle, resulting in Cardiac Ischemia; characterized by decreased blood flow and oxygen to the heart muscle. These conditions similarly affect the brain in carotid artery disease and the limbs and lower body in peripheral artery disease. While cholesterol reduces the flexibility of the vessels high blood pressure can cause thinning of arterial walls due to friction and abrasions, creating weak areas. With aging it takes more effort for the circulatory system to transport blood causing arteries to become weak, encouraging plaque build up in combination with high fat
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).
Ischemic Heart Disease or Coronary Heart Disease is a condition in which there is an imbalance in the oxygen demand and supply to the myocardial. An underlining cause of this is atherosclerosis, a process in which there has been a gradual build -up of fatty metabolic waste deposits (plaque) on the inside walls of the coronary arteries the vessels that supply oxygenated blood to the heart muscle. The coronary arteries eventually become mostly or completely blocked causing angina and can ultimately lead to a myocardial infarction due to the heart muscle not receiving adequate blood supply to function properly.
Coronary artery disease (CAD), also known as heart disease, is defined as the “narrowing or blockage of the arteries and vessels that provide oxygen and nutrients to the heart” (Milto, Odle, p.1). The main cause of CAD is an accumulation of fatty materials on the lining of arteries. Once the fatty materials line the inner arteries, it restricts blood flow to the heart. When blood is can no longer long flow to the heart, it causes a heart attack. Coronary artery disease is the leading cause of death in both women and men in the United States. The American Heart Association states that since 1990 deaths caused by the coronary artery disease have decreased, however, “more than 40,000 people still died from this disease in 2000” and about 13
Around 7 million men and women are affected yearly by a disease known as Coronary artery disease (CAD). If one has a reduction of blood flow going to the myocardium, they may have angina pectoris. Some people may not experience any pain, while others will have heart attacks, due to developing atherosclerotic plaques.
Several factors contribute to heart disease, there is no doubt about that. However, there are too many factors that contribute to heart disease. In, other words, medicine has not pinpointed factors that are more likely to contribute to heart disease—we don’t even know exactly what causes heart disease. Even then, there are still several factors that are being overlooked, or aren’t deemed as important.
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
Coronary artery disease (CAD) is defined as any type of vascular disorder that either narrows or occludes the coronary arteries. Atherosclerosis is the most common cause of coronary obstruction. Coronary artery disease causes ischemia. Moreover, persistent ischemia results in acute coronary syndromes such an infarction. An infarction can result in a heart attack. The rate of incidence is the U.S. is that, CAD results in more that 500,000 myocardial infarctions per year and is the cause of one-third of all deaths. A risk factor for CAD is hyperlipidemia, which can develop due to a high dietary fat intake. Another risk factor is hypertension or elevated blood pressure. Cigarette smoking, diabetes mellitus, genetic predisposition, and obesity
Cardiovascular disease (CVD) is caused by disorders of the heart and blood vessels, and includes coronary heart disease (heart attacks), cerebro-vascular disease (stroke), raised blood pressure (hypertension), peripheral artery disease, rheumatic heart disease, congenital heart disease and heart failure. CVDs are the number one cause of death globally.
