What Is Myocardial Ischemia?

The most common physiological process leading to a myocardial infarction is the occlusion of coronary arteries by a process known as atherosclerosis. In fact, atherosclerosis is present in more than 90% of persons with coronary heart disease.1

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.

Whether it is arteriosclerosis, congestive heart failure, broken heart syndrome, coronary microvasculature disease, or coronary heart disease, the National Institute of Health reports that "heart disease is the number one killer in the U.S.[and] also a major cause of disability." The good news is that there are things that can be done to lessen the chance of having a heart disease-related incident.

The heart in many cases does not have a correct beat and can cause symptoms like fainting, chest pain, heart fluttering, etc (WebMd.com). In some cases, Arrhythmia can be major as it can sometimes cause immediate heart failure or cardiac arrest (MedicineNet.com). The last main condition of cardiovascular diseases are strokes (Centers for Diseases Control and Prevention). A stroke is a point where the brain has an interruption of a blood supply (usually are blood clots). Strokes can block the blood that flows to the heart and can result in heart attacks, cardiac arrest, dizziness, slurred speech, etc (Centers for Diseases Control and Prevention). All of these conditions are the main aspects of cardiovascular disease (WebMd.com).

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 disease, sometimes called cardiovascular disease, is the narrowing or blockage of blood vessels around the heart. It is affected by many factors. Some of these factors include age, gender, obesity, high cholesterol, lack of physical activity, diabetes, hypertension, smoking, as well as genetic heart defects that one might be born with. The question now becomes how do these risk factors affect or impact heart disease. Are the factors necessary, sufficient, or component causes? Someone with a healthy heart will generally not have problems associated with heart disease, except perhaps though drug or alcohol use. Someone with heart disease, however, has a heart that has been damaged through one of the

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.”

Myocardium Infraction – MI is a very serious combination of family heritage and human behavior such as diabetes mellitus, hypertension, hyperlipidemia, smoking, sedentary lifestyle, and various factors which overtime damages the heart muscle and obviously its functions. MI or heart attack is worsening disease process. The narrowing of the coronary artery due to atherosclerosis, as well as plaque build-up of cholesterol which hardened the arteries or blood clots severely block and significantly reduced or stopped blood flow and oxygenation which become lethal ischemia and reperfusion. Consequently, MI is one of the leading causes of morbidity and mortality in the United States which every forty-three seconds, someone has a heart attack. Every year 735,000 Americans have a heart attack, which 525,000 are a first time, 210,000 are recurring, and one of five heart attacks is silent. The overall costing are between $192.1 billion and 321.6 billion

Because ischemic heart disease is caused by a lack of oxygen-rich blood to the heart, your heart may be damaged, even to the point of being unable to pump blood to the rest of your body. This condition is known as heart failure, which gradually weakens the entire body, causing swelling, coughing, lack of concentration, loss of appetite, and general fatigue. The electrical impulses of your heart may also be affected, leading to irregular heart

1 out of 100 people in the U.S are affected with ischemic heart disease. Ischemic heart disease is also known as ischemic cardiomyopathy and is commonly caused by atherosclerosis. Atherosclerosis occurs when the inner layer of coronary artery is hardened due to buildups of cells.

Myocardial infarctions are all too familiar in this day and age. Just about every person knows somebody who has either had a myocardial infarction. “About every 40 seconds, someone in the United States has a myocardial infarction (heart attack.” (American Heart Association, Inc., 2016). That means that roughly, in the ninety minutes of this class time, one hundred and thirty-five people have had heart attacks across the country. According to the CDC, “Every year, about 735,000 Americans have a heart attack. Of these cases, 525,000 are a first heart attack.” (CDC, 2015). So, what exactly is a myocardial infarction and what causes it to happen? There are several signs that could potentially alert an individual to

A heart attack, also known as a myocardial infarction, usually occurs when a blood clot forms inside a coronary artery at the site of an atherosclerotic plaque. The blood clot severely limits or completely cuts off blood flow to part of the heart. In a small percentage of cases, blood flow is cut off when the muscles in the artery wall contract suddenly, constricting the artery. This constriction, called vasospasm, can occur in an artery that is only slightly narrowed by atherosclerosis or even in a healthy artery. Regardless of the cause of a heart attack, the oxygen deprivation is so severe and prolonged that heart muscle cells begin to die for lack of oxygen. About 1.1 million people in the United States have a heart attack every year;

A person can be affected by ischemia for a short period of time or a long period of time. It can be happening as the person is resting or if they have a weak heart. A person who is over exerted physically, coronary artery disease, blood clots, or coronary artery spasm can be candidates for having ischemia. Symptoms of myocardial ischemia are: chest pain/pressure with is normally on the left side which is also known as angina pectoris, neck/jaw pain, shoulder/arm pain, a

Myocardial infarction occurs when one of the coronary arteries become blocked, and can no longer carry oxygenated blood to the heart muscle. If the heart muscle does not receive oxygenated blood, the heart tissue begins to die. 42% of all deaths from cardiovascular disease is caused by myocardial infarction. Sometimes there is no symptoms, but most people may experience chest pain, shortness of breath, dizziness, or nausea. The pain could be mild or severe, and persistent or intermittent.

A heart attack, or myocardial infarction, is a common condition that is life-threatening and very unexpected. It is caused by one or more blockages in the coronary arteries, cutting off blood flow to the heart as well as causing extensive tissue damage. These blockages are usually caused by an excess of fat and cholesterol. A few symptoms of a myocardial infarction include pressure in the chest, shortness of breath, sweating, dizziness, and a rapid heart beat. Your risk of having a heart attack increases if you have high blood pressure, high blood sugar levels, and high cholesterol levels; the risk also increases in smokers and those who are over fifty years old.
