Coronary Artery Homeostasis

The signs and symptoms that you need to look out for include the most common chest pain and discomfort which likely happens during physical activity or after meals. However, chest pain may also occur with rest. The lower extremities are swelling and feelings of weakness and fainting also occur. Heart palpitations are present due to the abnormal heart

A heart attack, or myocardial infarction, is where one of the blood vessels within the heart becomes completely blocked off and there is significant damage and sometimes death of

A heart attack occurs when the oxygenated blood that typically flows to the heart muscle is severely reduced or cut off. This happens because the coronary arteries that supply the heart with blood slowly become narrow from built up plaque. If a piece of plaque breaks off, a blood clot typically forms around the plaque and the clot can block the blood flow through the heart. When blood flow is blocked, the muscles of the heart becomes starved for oxygen and nutrients, this is known as ischemia. Because the body needs oxygen to carry out vital life processes, ischemia can cause damage or death to parts of the heart muscles. When damage occurs it is called a heart attack or myocardial infarction (American Heart

A heart attack occurs when an artery that supplies blood to the heart becomes blocked. The loss of oxygen and nutrients damage the heart's muscle tissue, causing the remaining healthy tissue to pump even harder to keep up.

lives. A simple definition of a heart attack is a sudden failure of the heart

Myocardial Infarction (MI) is more commonly referred as the heart attack. This typically occurs due to an interruption, albeit partial to some part of the heart, which causes the cells in the heart to die and as a result sends

Heart muscle died as a results of myocardial infarction (MI) which the main coronary arteries was blocked, and large part of the heart muscle was affected due to cellular death from lack of blood flow and oxygen. Cell death is one of the most crucial events in the evolution of MI. A heart attack or MI is usually caused by a blood clot (thrombosis) that forms inside a coronary artery, or one of its branches, which suddenly blocks and stops the blood flowing to a part of the heart muscle. When the blood flow is interrupted necrosis occurs ( McCance & Huether, 2014).

Some symptoms of heart failure are weight gain, swollen feet and ankles, fast or irregular pulse, palpitations, fatigue, weakness, loss of appetite, faintness, nocturia, shortness of breath especially during physical activities or while at rest, enlarged abdomen and liver.

Heart failure is term that is used to describe the heart’s inability to work efficiently as a pump. In order to decipher if an individual is likely to have heart failure is through their health history. Common backgrounds associated are diabetes mellitus, kidney dysfunction, hypertension, chronic lung disease, angina, myocardial infarction, and ischemic heart disease (Kirk, 2011). It is accompanied by shortness of breath on exertion, decreased exercise tolerance, paroxysmal nocturnal dyspnea, orthopnea, ankle swelling, sudden weight gain, lack of appetite or nausea and difficulty concentrating (Kirk, 2011). In worsening conditions it could progress to fluid buildup, rapid or irregular heartbeat, chest pains , and sudden

The heart is an organ that pumps blood from the body and maintains all the organs functioning to keep one alive; when one of the arteries that receive blood is blocked it can cause a heart attack or myocardial infarction (MI). “During a heart attack, the heart muscle (the myocardium) is damaged, and part of it die from lack of blood” (book, p. 429).

Heart failure is a condition in which the heart muscle is unable to pump enough blood through the heart to meet the body’s need for blood and oxygen. Coronary artery disease is a form of heart disease that effects the chambers of the heart. There are four chambers in the heart. The upper chambers consist of a right and a left atrium and the lower chamber consists of the right and left ventricles. The flow of oxygen rich blood travels from the lungs to the left atrium and into the left ventricle where it is pumped into the rest of the body. When the heart functions properly, all four chambers beat and pump blood effectively in an organized way. The Virtual Medical Centre (Centre, 2008) newsletter states that "Management,

A network of coronary arteries and blood vessels supply the surface of the organ with oxygenated blood. If anything obstructs this blood supply, the muscle can become damaged. This is known as a heart attack.

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

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.

     Heart attack occurs when a blood clot suddenly and completely blocks a diseased coronary artery, resulting in the death of the heart muscle cells supplied by that artery. Coronary and Coronary Thrombosis 2 are terms that can refer to a heart attack. Another term, Acute Myocardial Infarction 2, means death of heart muscle due to an inadequate blood supply.
