Myocardial Infarction And The Heart Attack Essay

A heart attack is where the a blockage of the blood vessels cuts off blood supply to an area of the heart. The cause of this blockage is a process that occurs over several years known as 'atherosclerosis'. Atherosclerosis begins with cholesterol in the blood becoming lodged in the vessel walls. There are many other factors that influence the progress of this atherosclerosis. This causes the vessel wall to swell, resulting in a smaller vessel for blood to flow through. If this narrowing is severe enough, the entire blood vessel can become blocked, which is a heart attack. As the heart muscle does not receive enough

In December of 1992, my paternal grandfather suffered a heart attack. He had been hauling several 50 lb. sacks of corn up into the deer feeder on his property by himself. He got into his truck, turned the ignition, put it into drive and before he could take his foot off the brake, he was dead. He was 68 years old. I was thirteen and that seemed so old. I remember that prior to the event there were many conversations within my family about the condition of my grandfather’s heart and cardiovascular system and how he needed to make lifestyle changes. I remember him taking nitroglycerine pills. I remember him coming to Dallas to go to an appointment so that they could perform tests with names like “stress EKG.” I

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.

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.

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).

e) Myocardial infarction: Myocardial infarction is a heart attack. “Myocardial infarction occurs when blood supply to a part of the myocardium is interrupted. This can be caused by a lack of blood flow, obstruction by a clot, or a rupture of plaque build up.”

Coronary Heart Disease Coronary heart disease remains the most common cause of death in the United Kingdom. A statistic from the American Heart Association is that heart disease claims a life every 24 seconds. [www.americanheart.org] Another is that it is

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).

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.

There are many causes of heart failure. Among them is a reduction in the contractile ability of the heart due to mechanical problems or any problem that limits the filling capacity of the heart chambers with blood due to any form of cardiomyopathy. Whatever the cause, the patient’s tissues are compromised because they cannot receive an adequate amount of oxygen necessary to perform optimally (Bui, Horwich, & Fonarow, 2010).

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

     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.

This slow process is known as Atherosclerosis. When a plaque in a heart artery breaks, a blood clot forms around the plaque. This blood clot can block the blood flow through the heart muscle. When the heart muscle is starved for oxygen and nutrients, it is called Ischemia. When damage or death of part of the heart muscle occurs as a result of ischemia, it is called a heart attack or myocardial infarction (MI). About every 34 seconds, someone in the United States has a myocardial infarction (heart attack)” (“Atherosclerosis”)

Heart attack is blockage of blood flow to heart muscle. Heart attack is also called myocardial infraction. Heart muscles needs oxygen to survive. A heart attack happens when the flow of oxygen rich blood to a section of heart muscle suddenly becomes blocked and the heart cannot get oxygen. If blood flow is not restored quickly, the section of heart muscle begins to die. This happens because coronary arteries that supply the heart muscles with blood flow can slowly become narrow from build-up of fat, cholesterol and other substances.
