Pathogenesis of Coronary Heart Disease

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

The cardiovascular disease defines conditions that affect the heart or blood vessels. Thrombosis, which emanates from blood clots, reduced blood flow to the heart, brain and the rest of the body. When fatty acids deposit in the artery, it hardens and narrows. These issues lead to stroke, coronary heart disease, aortic disease and peripheral arterial disease. Coronary heart disease occurs due to a reduced or blocked flow of oxygen-rich blood to the heart. It is a result of accumulated fats in the coronary arteries. Coronary arteries are a set of blood vessels that take blood to the heart. When they become narrow, the heart gets less of a supply of blood and oxygen causing chest pains, called angina or a heart attack, explains VanMeter &

Have you ever imagine a body functioning without a heart? The heart, the center of the cardiovascular system, is the essential manager for just about everything that gives the body life. Correspondingly, most of the heart diseases are fatal and cannot be ignored. In fact, "heart disease is the leading cause of death for women as well as men"(1). According to the Centers for Disease Control and Prevention, every 25 seconds someone has a coronary event(1). One of these diseases is coronary heart disease (CHD). "CHD is a condition in which certain substances builds up inside the coronary arteries"(2). When these substances block the flow of oxygen-rich blood, heart attacks most often occur. Heart attack, also known as myocardial infarction, is a serious event and a leading killer that has numerous symptoms and certain risk factors.

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)

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)

Most of the conditions in cardiovascular diseases can be prevented by methods like identifying the symptoms and maintaining a healthy lifestyle (Centers for Diseases Control and Prevention). Symptoms of cardiovascular diseases can vary depending on the severeness of the condition itself. Symptoms may include chest discomfort, shortness of breath, swelling, weakness, dizziness, and/or pain and numbness in parts of the body (MedicineNet.com). If one experiences these symptoms, it is best to seek medical advice on what to do next. Chest discomfort can include chest pain, fluttering in the heart, and chest tightness (Centers for Diseases Control and Prevention). Pain near

Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These

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

Heart disease is formed when plaque buildup thickens and stiffens artery walls. Causing it to

Serious causes for chest pain include: Acute Coronary Syndromes (ACS): New onset angina, accelerating or crescendo angina and prolonged angina or coronary insufficiency, non ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial infarction (STEMI). The typical features of cardiac chest pain are 1.) located under the breastbone or at least some of the pain is situated in this area, 2.) other features include provocation by exercise or stress and 3.) relief by rest or nitroglycerin. If all three features are present the patient is

Coronary artery disease is one of the common forms of heart disease. It’s caused by the narrowing occurs in the coronary arteries so that reduces the flow of blood to the heart tissues. Through the artery is gradually narrowing because of a substance called plaque builds up inside the wall of coronary arteries, the heart may not get enough blood to work. (coronary artery disease)If the plaque ruptures, a blood clot can form around on its surface. Over the time, the blood clot can completely block the pathway, which can’t let any blood to go through.

Similar to other diseases coronary heart disease affects thousands of people. The disease affects the heart in that it causes a waxy substance called plaque where it builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. When a person has coronary heart disease the hardened arteries restrict blood flow, which means that the heart cannot receive enough oxygenated blood, especially when it beats quickly during physical exertion or stress. This can cause chest pain and shortness of breath. However, if the artery is completely blocked, a heart attack can occur. Lack of oxygen during a heart attack causes damage as the heart muscle dies and is replaced with scar tissue. If damage is severe, the heart

Heart Disease, also known as Cardiovascular Disease is abnormal function of the heart or blood vessels. There are many different types of heart disease. “Heart Disease” is just a word that describes the many other conditions and diseases there is that can affect our heart. The causes of heart disease are stressing, eating too much fatty foods, stressing, drinking a lot of alcohol, and not being active. Coronary Heart Disease is the leading heart disease in the United States. Coronary arties surround the heart and provides the heart with the energy and oxygen it needs (Lehnardt, 2016). Almost 2,500 Americans die before they can get to the hospital. You can prevent heart disease.

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
