The Coronary System

Another word used to describe a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. A heart attack is the death of a part of the heart caused by the loss of blood supply. The blood supply is usually gone due to a coronary artery being blocked by a blood clot. When a part of a heart artery breaks a blood clot forms around the piece. This blood clot can block the blood flow through the heart muscle. When the heart muscle needs oxygen it is called ischemia. When damage of a part of the heart muscle happens it’s called a heart attack. During a heart attack damage occurs depending on the size of the area blocked by the blood clot as well as the time between the actual heart attack and the treatment. Even though the heart may be hurt, the rest of the organs work with no problems. However, it will not pump as much blood as it used to in order to supply the same amount of blood to all of the parts of the body.

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

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

Coronary artery disease is the most common cause of a myocardial infarction (MI). As a result of CAD, plaque builds up in the arteries, thus narrowing the coronary arteries and preventing adequate blood flow to the heart. This condition is called atherosclerosis. In 2012, Huether, S., & McCance, K. defines Atherosclerosis when it begins to occur when there has been an injury to the coronary vessel wall. When injury occurs on the vessels endothelial layer it triggers a clotting mechanism. That mechanism sends chemotaxsis signals through the body for monocytes/macrophages to come clean the open vessel wall that is leaking LDL into the blood. The macrophages attempt to digest the fatty substance but have a hard time doing so. When the cells cannot digest the LDL, cell proliferation happens and they become static. Static macrophages turn into foam cells that then begin to cover the open vessel wall. Stasis of these foam cells occurs and forms a fatty streak, beginning to slowly occlude the artery. Then with time, build up of collagen occurs on top of the

Atherosclerosis develops over the course of 50 years, beginning in the early teenage years. The causes of this process appear to be lipid retention, oxidation, and modification, which provoke chronic inflammation at susceptible sites in the walls of all major conduit arteries. Initial fatty streaks evolve into fibrous plaques, some of which develop into forms that are vulnerable to rupture, causing thrombosis or stenosis. Erosion of the surfaces of some plaques and rupture of a plaque's calcific nodule into the artery lumen also may trigger thrombosis. The process of plaque development is the same regardless of race/ethnicity, sex, or geographic location, apparently worldwide. However, the rate of development is faster in patients with risk

Studies looking at coronary collateral circulation in humans are typically more controversial. Skeptics have stated that collateral development is probably due to the progression of coronary artery disease rather than an effect of exercise training. In addition, direct measurement of collateral growth, typically through coronary angiographic techniques, is difficult and may have severe limitations due to low levels of resolution of vessels (Heaps et al., 2011). Small vessels involved in the coronary collateral system (<100μm) are incredibly difficult to view angiographically, so the full magnitude of collateralization may not be assessed or may be drastically underestimated (Heaps et al., 2011; Belardinelli et al., 1998).

The coronary arteries are the main arteries supplying blood to the heart and contains the same layers of a typical artery but is known as an atypical blood vessel. The walls of coronary arteries is usually thicker

The cardiovascular system is a piece of the more extended circulatory system, which circles liquids all through the body .The circulatory system incorporates both the cardiovascular system and the lymphatic the system. The cardiovascular system moves blood all through the body and the lymphatic system moves lymph. Which is a reasonable liquid that is like the plasma in blood?

Based on the initial complaint of chest pain and palpitations, the following disorders are possible causes of the

The left main coronary artery provides blood to the left part of the heart (e.g. left atrium and left ventricle). In particular, the left main coronary branches off into the circumflex artery and the left anterior descending artery. If there is occlusion in the circumflex coronary, then there is infarction in the left atrium and the side and back of the left ventricle. In addition, if there is blockage in the left anterior descending artery, then there is infarction in the front and bottom of the left ventricle, and the bottom of the sepum.

In the department of Cardiology coronary artery disease is a major disease in the world. Coronary artery disease is the damages of the hearts major blood vessel for fat deposits. (2017, April 26) Plaque restricts the blood flow to the heart, which in the end progresses to a myocardial infraction also know as a heart attack, which is another major condition in the department of cardiology. When a patient is suffering from CAD, they may experience angina (chest pain) in the thoracic region that could circulate to their arms and neck. Arrhythmia can also occur, whether or not if it’s fast or slow paced. A patients pulse could also change depending on what is going on with the patient at the time. When a patient has CAD (coronary artery disease), there are a few procedures that are required from them on a monthly to yearly bases. Cardiac Catherization is one which is a procedure performed by passing a catheter into the blood vessel to see if there is any blockage in the arteries. (2017)

There are many things that men and women that obtain differently. There is a disease that is the top death rate (Krucik, 2014). That many more women get than men. Coronary Artery Disease is the disease that is more common in women than men. Coronary Artery Disease, but it is also known as Coronary Artery Disease and Ischemic Heart Disease, is when the arteries that supplies blood to the heart muscles become hardened and narrowed. It is caused by the buildup of cholesterol and plaque on the inner walls and it also can because of smoking and aging.

This paper will discuss to you the pathophysiology of coronary artery disease and the effects it has on the body. Coronary artery disease (CAD) is the most common form of heart disease there is, and it causes much suffering and pain in those who acquire the disease. In this essay, I will discuss with you the disease process, risk factors, signs and symptoms, complications and the collaborative care provided. I will also compare my patient’s clinical manifestations to the pathophysiology of Coronary artery disease

A healthy, normal heart has two strong pumps. One pump uses arteries to push blood with oxygen through the body and away from the heart. The other uses veins to bring blood back into the heart then the lungs to get more oxygen. The main blood supplier, the aorta, branches off into two of the main coronary arteries into smaller ones.
