Myocardial Infarction Essay

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.

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.

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

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.”

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).

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.

Sudden Cardiac arrest is the leading cause of death in the United States, killing around 325,000 people a year.

Chest pain (angina) is an indicator of a heart attack (myocardial infarction). A heart attack can cause sudden death.

Perhaps the most deadly of all the heart’s complications is a heart attack. A heart attack is the leading killer in men and women in the United States, with an estimate 1 million heart attacks alone in the United States (NHLBI). A heart attack occurs when the heart is unable to obtain oxygen, due to a section of heart muscle becoming blocked and preventing oxygen-rich blood to flow properly. The leading cause of heart attacks is coronary heart disease, also known as coronary artery disease. Coronary heart disease is a result of plague, a waxy like substance, building up inside the coronary arteries, the arteries that are responsible for providing blood to the heart (NHLBI). Overtime, the built up plaque can rupture inside of an artery causing a blood clot to form, which prevents blood from reaching heart muscles. Portions of heart muscle once fed by this now blocked artery begin to die if blockage is not treated in time.

The first step in the prevention process 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, or 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 result when oxygenated blood does not reach a section of the heart, and the section

     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.

Sudden cardiac death (SCD) is one of big medical challenges that threaten our life and it is left over very tragic memories among family’s members(Adabag et al., 2010). Clinically, it is firstly associated with stopping the activity of cardiac muscular tissue, thereafter turning off the blood pump and finally permanent damage of brain tissue(Go et al., 2014). Despite the lack of having a clear definition of SCD, the most acceptable description is that the sudden cardiac death is unexpected death that can be happened within 60 minutes from the symptoms being appeared and approved by witnesses, or it may be occurred during a period of 24 hours in a person who has clearly been found in a healthy condition when the death is not witnessed(Uchmanowicz et al., 2015). According the definition above, around 35-40% of the total cases of SCD are happened out of hospital which is namely known, Out of hospital sudden cardiac death (OHSCD((Basso et al., 2010). Cardiac arrhythmia resulted from myocardial infarction is classified to be the most important causes leading to the OHSCD. However, other causes like Angina pectoris, unspecified

Since the heart is a muscle it also needs its own supply of the blood circulating around it. Once the blood is oxygenated and travels through the aortic valve. There are two sets of arteries, the left main coronary artery and the right coronary artery, that bring the blood back around through the heart muscle. Blockage to any of these arteries will trigger a myocardial infarction, commonly known as a heart attack.

Myocardial infarction (MI), also known as heart attack is characterized by a lack of or total obstruction of blood flow to the heart. This will eventually reduce oxygen flow
