Coronary Artery Disease is the most common type of heart disease and is the leading cause of death in the United States in both men and women. It is caused by a buildup of cholesterol and other materials on the inner walls of arteries. The buildup is called atherosclerosis. As the buildup grows the heart gets less and less blood supply thereby depleting it of oxygen. This eventually leads to chest pain (angina) or a heart attack which is usually caused by a clot that suddenly breaks off the hearts blood supply which causes permanent heart damage. Over time, if this condition continues it can eventually lead to heart failure and arrhythmias. An arrhythmia is a change in the heart’s normal beating process (MedlinePlus 2015). Coronary Artery disease is caused by damage or injury to the inner layer of a coronary artery and can be caused by a number of factors. Some of them are; smoking, high blood pressure, high cholesterol, diabetes or insulin resistance, and/or a sedentary lifestyle. After the wall of an artery is damaged it makes it much easier for fatty deposits (plaque) such as cholesterol and other fatty waste products to build up on the linings of artery walls. This process is known as atherosclerosis. If this plaque breaks or ruptures platelets will clump at the site to try and repair the artery, but this can also block the arteries which can lead to a heart attack. The main factors that place a person at risk for this disease are age, as getting older is
The first step in understanding the risk factors for women is understanding the disease itself. Coronary artery disease and coronary heart disease are terms usually used interchangeably. In actuality, coronary artery disease causes coronary heart disease (CHD). Heart attacks are then the result of CHD. Coronary arteries originate in the aorta and function to supply oxygenated blood to the muscular tissue of the heart. Plaque can build up and block these arteries over several years, reducing the flow of oxygenated blood to the heart. Eventually, the plaque can harden or even rupture, which increases the risk of a blood clot formation because platelets are attracted to the site. If a blood clot forms, the coronary arteries can become completely blocked. Heart attacks
Coronary artery disease affects the circulatory system. Chemically, this disease develops when blood vessels that are necessary for living become badly damaged. Cholesterol plaques become inflamed in the arteries. The most common signs and symptoms are chest pains which tighten the chest as if someone were standing on it. Shortening of breath also affects those with this disease because the heart is unable to supply enough blood. A major sign of this disease is having a heart attack. This indicates an artery that is completely blocked. This disease is caused by damaging the coronary arteries by smoking, diabetes, high blood pressure or high cholesterol. To diagnose this disease, medical physicians will perform physical exams and examine blood
Nevertheless, there is an understandable and noticeable link between circulatory related diseases and lifestyle diseases, such as Coronary Heart Disease. Coronary heart disease can occur when fatty acids, such as cholesterol in an inadequate diet, build up in the walls of the coronary artery. These fatty deposits collect minerals and harden to become a plaque. Eventually, this plaque grows and can swells up, forming an aneurism. In some cases, this aneurism may burst leading to instant death. As it continues to grow and swell up, it finally blocks the artery completely and forms blood clots. This is known as coronary thrombosis. A myocardial infarction, or in other words as heart attack, occurs when no oxygen is able to reach the coronary artery and thus it is unable to fulfil its role in providing the heart muscle with a sufficient supply of blood. Heart attacks are very common in the society nowadays, especially occurring in smokers or obesity related diseases (Millar, June 2014)
Cholesterol and fatty deposits build up in the heart's arteries, causing less blood to reach the heart muscle. The muscle becomes damaged and the remaining heart tissue has to work harder.
Cholesterol can build up on the inner walls of arteries forming thick hard plaque deposits that make the arteries less flexible and cause narrowing. This narrowing can cause a slowing of the blood flow to your heart. A reduced blood flow means less oxygen can get to your heart, and this is coronary heart disease. If a clot forms and blocks the artery,
Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)
The heart disease is one of the killer diseases among the American women. The heart disease is a heart group disease and the heart's blood vessel system. The most common type of heart disease is the Coronary heart disease. The Coronary disease affects the human blood vessels in the heart causing a heart attack or the angina (Gregson, 2009). Angina is a type of condition whereby an individual experiences chest pains in case the heart fails to get enough blood. An individual usually experiences sharp pressing chest pains but sometimes the back, shoulders and arms are also affected. Some of the
It occurs when plaque develops in the arteries and the blood vessels, blocking many important nutrients and oxygen from reaching your heart (Heart Disease Causes - Mayo Clinic). This usually results from obesity, diabetes, high cholesterol, being physically inactive, smoking, eating an unhealthy diet, clinical depression, or a family history of heart disease (Heart Disease Causes - Mayo Clinic). If you're going through any of the things listed above, then you should take it within yourself to start making some changes in order to prevent heart disease, and you can do that by, exercising regularly, maintaining a healthy diet, maintaining a healthy weight, reducing stress in your life, stop smoking, stop drinking, start taking supplements as advised by your doctor, and start getting annual physicals from your doctor to detect abnormalities, to assess risk factors, and to know the warning signs of heart disease, heart attacks, and strokes(Heart Disease Causes - Mayo
Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis. Atherosclerosis is the narrowing and thickening of arteries and develops for years without causing symptoms. It can happen in any part of the body. Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease. The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack. (World Heart Federation).
The most common heart disease that most people have is coronary artery disease. Coronary artery disease tends to cause heart attacks. When a substance of plaque builds up in your arteries, heart disease may occur. When plaque builds up, a person’s arteries can narrow over time, limiting blood flow to the heart. This could also block the blood flow. This process is called
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.
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).
It is not only the leading cause of death in the United States, but also it is the most common type of heart diseases. By killing nearly 380,000 people yearly, and that is about every 60 seconds someone dies from it. Yes, it is the heart attack or also known as coronary heart disease. Heart attacks occur when one of the coronary artery is blocked or narrowed by fats. After that, the blood clot will gather and block the narrowed artery causing a slowly painful death to the artery by decreasing the amount of oxygen, and replacing the live tissue with a dead one.
Coronary artery disease (CAD) is caused by fatty buildup in the arteries of the heart. Your arteries are made to carry oxygen infused blood to your heart and other parts of your body if it is filled up with plaque, which is the fatty substance that clogs and blocks up the arteries. If it gets clogged enough to where your heart is not receiving fresh oxygen, you could have a heart attack that could cause very serious damage to your body and could even kill you. When you are younger, you can begin to grow plaque in your blood vessels from not eating right and not exercising regularly. When your arteries are being filled up with plaque they become more narrow and harder for blood to get through as easily as it is supposed to be. When you have
Atherosclerosis is the process in which substances known as plaques, which are made up of cholesterol and platelets, adhere to tears in the walls of arteries. Over time these plaques build up to the point where they occlude blood flow in the arteries. When this happens in the coronary arteries, either directly, as the result of buildup in the arteries themselves, indirectly in the form a clot from another part of the body breaking loose and becoming lodged in the coronary arteries, the usual result is a heart attack.3
