What is myocardial ischemia?

Myocardial ischemia is owing to poor blood supply and infarction is due to no blood supply. The severity of both differs and ischemia can progress to infarction.

what is the meaning of negative for provocable ischemia

myocardial infarction

Myocardial ischemia results from the temporary lack of oxygen; if ischemia is prolonged, it could result in permanent damage to the heart muscle. This condition is called myocardial infarction, commonly known as a heart attack. ischemia

muscular system

Myocardial ischemia is a coronary artery disease during which the heart tissue is slowly or suddenly starved of oxygen and other nutrients. Eventually, the affected heart tissue will die.

When blood flow is completely blocked to the heart, ischemia can lead to a heart attack .

Myocardial ischemia is caused by blockage of an artery due to atherosclerotic plaque as well as blood clots (which tend to form on plaque), artery spasms or contractions, or any of these factors combined.

Reversible myocardial ischemia is a condition in which areas of myocardium becomes ischemic during stress (exercise) but regain its viabililty (circulation) on resting and do not progress to infarction. Such areas can be detaected by myocardial perfusion imaging like Thallium (T-201)scan.

Myocardial ischemia.

Myocardial Ischemia

Cardiovascular system

This is called Myocardial Ischemia. This can be deadly

myocardial infarction,stroke, ischemia, infarction, intermittent claudication

The ECG sign of subendocardial ischemia is ST segment depression. Note that ECG is used more now that EKG.

Acute myocardial ischemia happens when the coronary artery gets blocked. As a result the blood and the oxygen supply to the heart reduces and the heart muscles can not work properly. This means heart fails to pump efficiently leading to a cardiac arrest.

The risk factors for myocardial ischemia are the same as those for coronary artery disease. For TIA, coronary artery disease is also a risk factor.

Ischemia or a deficiency of blood flow to the heart causes a heart attack.

Myocardial ischemia or infarction. (Heart attack)

According to the American Heart Association, up to four million Americans may have silent ischemia and be at high risk of having a heart attack with no warning.

A proof that a particular problem cannot be solved, or irreversible, ischemia mean that Inadequate blood supply (circulation) to a local area due to blockage of the blood vessels to the area.

The natural biologic response to repeated myocardial ischemia (insufficient oxygen levels in heart muscle) is angiogenesis, the growth of new collateral blood vessels. http://www.cardiumthx.com/science-technology-overview.html

what is the medical term meaning obtaining fluid from a joint in order to examine for diagnosis

Yegor Gaydar died on December 16, 2009, in Odintsovo, Moscow Oblast, Russia of pulmonary edema caused by myocardial ischemia.

Yes. You give rest to the patient. Put nitroglycerin tablet sublingually, and give 100% oxygen to patient. He should recover.

Yes, angina pectoris is due to inadequate blood supply or ischemia. Prolonged ischemia however may progress to necrosis wherein the heart cells die. In this instance it is now called Myocardial Infarction or a heart attack.

Myocardial ischemia is the term meaning insufficient blood flow to the heart muscle.

in myocadial ischemia, pain radiate to jaw, neck,shoulder,arm wheras in aortic dissection pain radiate to back, between scapulae there is differense between pulse rate of both arms and leg depending on ecg changes

Diagnostic tests include: resting, exercise, or ambulatory electrocardiograms; scintigraphic studies; echocardiography; coronary angiography; and rarely positron emission tomography.

it will cause deposition of cholesterol in the artery, narrowing it's lumen and may lead to ischemia, and worst obstruction may lead to myocardial infarction.

A lack of adequate blood supply to the heart is called Myocardial ischemia. It usually occurs when a blockage is present in one of the blood vessels supplying the heart.

A depressed ST wave can mean a number of things. It can be caused by some medications (digoxin), by ischemia in the heart muscle, and also by a myocardial infarction on the posterior surface of the heart (if seen in V1 or V2). ST depression may also be seen as a reciprocal change in leads away from the site of the myocardial infarction.

Myocardial ischemia is the medical term meaning inadequate oxygen to the heart. If it is prolonged, it may result in myocardial infarction (heart attack), which is tissue damage due to lack of blood flow. During the period of inadequate oxygen delivery, a person may feel crushing chest pain called "angina pectoris."

Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as…

Ischemia means a reduced blood supply to an organ or body part. Antero- refers to the anterior, or front side of something. -lateral means to the side or the outside of something. So to put it all together Anterolateral Ischemia means that there is or was a reduction of blood flow to the front outside part (of an organ). This is often a term used to describe findings after chest pain or a heart attack…

Angina is chest pain due to ischemia (a lack of blood, thus a lack of oxygen supply and waste removal) of the heart muscle, generally due to obstruction or spasm of the coronary arteries (the heart's blood vessels). Myocardial Infarction is cellular death of the heart muscle due to lack of oxygen, often caused by blockage of arteries. Essentially angina proceeds a myocardial infarction, both are caused by low/no oxygen reaching some part of the…

There are many potential causes from pathological causes to genetics, some of them I can list for you below: Disease/genetic mutation affecting the heart muscle cells High blood pressure (hypertension) Aneurysm Thyroid diseases Coronary artery disease --> the most common Myocarditis or endocarditis Obesity Old age Myocardial Infarction/Myocardial Ischemia Heart valve disease

The risk factors are hereditary, sex, age, smoking, high cholesterol, high blood pressure, high fibrinogen, stress, anger, high homeocysteine, oxidant damage, lack of physical activity, diabetes, obesity.

It is a coronary heart disease, where the heart and tissue are starved slowly or suddenty from oxygen and other nutrients, and when blood flow is blocked complety. Eventually the heart tissue will die. this can lead to a sudden heart attack to the patient with the problem.

An arheroma is a plaque made from cholesterol. When it breaks off it forms a clot in the blood stream. If this clot clogs an artery that feeds the heart muscle, it can cause ischemia (tissue hypoxia) or infarction (tissue death).

The heart muscle is not getting enough blood. The blood supply is actually so important that the flow from the large aorta has an artery that goes to the muscle's surface before it goes to the rest of the body. If this can not be 'fixed' in someway, the heart muscle die from lack of enough oxygen.

Usually a stenotic coronary artery caused by atherosclerosis. The stenotic (narrowed) artery can give a brief period of ischemia (withholding of blood) to a region of the heart, which is felt as an intense pain. Angina pectoris is a sign that a more serious episode of ischemic attack can happen for that artery. If it is left untreated, it is very likely that the artery will eventually become completely clogged and the ensuing prolonged ischemia…

Anterior wall ischemia

Inferoapical ischemia is lack of blood flow below the apex.

Brain ischemia (cerebral ischemia or cerebrovascular ischemia) describes brain dead tissue. In layman's terms, a "stroke".

In many cases, ischemia can be successfully treated, but the underlying disease process of atherosclerosis is usually not "cured." The outcome for silent ischemia has not been well established.

what is reversible vs irreversible ischemia in the brain

It depends where the obstruction and ischemia are suspected of being located.

Cerebral ischemia is a condition where the brain or parts of the brain do not receive enough blood-flow to maintain normal neurological function. http://www.answers.com/topic/ischemia

This means relating to the muscle tissue of the heart. Here are some sentences. He suffered a myocardial infarction, or heart attack. The disease caused myocardial damage. He has a myocardial infection.
