there really isn't any such thing as an ischaemic artery (it can happen, but I've never heard of it!). Rather ischemia (or ischaemia for our English and Australian friends) is a lack of sufficient oxygen delivery to a tissue. Oxygen is carried by HEMoglobin in the blood hence the iscHEMia. Ischemia is usually caused by an interruption to the blood flow to a particular area. One way to interrupt blood flow is to block an artery. (which usually deliver oxygenated blood to tissues) A blockage may be the result of a plaque (a fatty aggregation on the inside walls of an artery), or a thombus (clot), or an embolus of some sort. People often hear that they may have ischemic Heart disease. This is a condition of severely narrowed arteries (often greater than 70% of their cross sectional area may be blocked) which leads to decreased blood (and hence oxygen) supply to the muscle of the heart. This can cause Angina. If the coronary arteries completely block off, then a heart attack will ensue, where cardiac muscle dies because of lack of oxygen. Treatment ranges from medications to: lower cholesterol, decrease oxygen consumption of the heart, vasodilators to increase delivery of blood through that artery; to surgery to operate and either re-open the blocked vessel (balloon angioplasty and stenting ) or procedures to essentially replace the diseased vessels in By-pass surgery (CABG- coronary artery bypass grafting). Hopefully that helps!! Aj :)

Iscehmia in the arteries of the brain can lead to stroke. About 80 - 85% of all strokes are ischemic.
Ischemic heart disease is a medical condition described by a restricted blood flow through arteries in the heart muscle. These arteries cannot carry sufficient oxygen to several areas of the body supplied by such blood vessels. This condition can result in a heart attack.
YES. Hypercholesterolemia or Dyslipidemia is harmful if not treated immediately. It can cause blockages in the arteries or narrowing of arteries that may lead to insufficient supply of blood to the brain, thus resulting to Transient Ischemic Attack or CVA.
Ischemic heart disease is basically reduced blood going to the heart. You have a blockage in the arteries which causes the blood flow to decrease with this disease.
TIA is the abbreviation for transient ischemic attack.
Assuming that you mean ischemic heart disease, it is the same as coronary artery disease, where the arteries harden. It can be caused by a build up of cholesterol and prolonged exposure to certain herbicides.
Ischemic necrosis is tissue death due to impairment of blood flow.

The definition of an ischemic stroke is an obstruction with a blood vessel supplying blood to the brain. There are two main types of ischemic stroke embolic and thrombotic.
Ischemic strokes account for about 80% of all strokes.
Ischemic stroke, or often, an ischemic transient attack, or TIA.

A Blood clot formation in any part of the carotid arteries may produce carotid stenosis; occlusion of the vessel and can cause transient ischemic attack, cerebral infarction etc.,
It can be. My mother lost 90% of her small bowel due an ischemic bowel and passed from subsequent complications.
Ischemic heart disease is a condition of recurring chest pain or discomfort that occurs when a part of the heart does not receive enough blood. This condition occurs most often during exertion or excitement, when the heart requires greater blood flow. The signs and symptoms of ischemic heart disease may develop slowly as arteries gradually become blocked, or they may occur quickly if an artery suddenly becomes blocked. Some people have no symptoms. While others can have severe chest pain and shortness of breath.
Ischemic colitis is a medical condition in which inflammation and injury result from unhealthy blood supply. Ischemic colitis occurs when blood flow to part of the large intestine is reduced due to narrowed or blocked blood vessels.
Well, strokes don't cause clots, but sometimes ischemic strokes are caused by blood clots.
Transient ischemic attack is a brief episode of lack of blood flow to part of the brain.
As the name suggest, ischemic heart disease is a disease of the heart. However you need to understand that the term 'ischemic' means that lack of blood supply. This then suggest that the actual problem is the lack of blood supply to the heart muscle (myocytes). Ischemic heart disease can predispose to many other cardiovascular condition such as angina, myocardial infaction and arrythmia.
Chronic microvascular ischemic changes are when there are tiny blood vessels in the brain that have ruptured or clotted. This causes very small strokes.
No. A transient ischemic attack, also known as a "mini-stroke", is when a person has stroke like symptoms that resolve within 24 hours. I it due to a lack of blood flow to some part of the brain. Ischemic heart disease is when there are blood flow problems to the heart. It usually manifests as chest tightness or pain and shortness of breath is exertion but the symptoms can vary widely.
Superior phrenic arteries, Musculophrenic arteries, and Inferior phrenic arteries.
There are no arteries actually in the heart, but there are two main arteries on the outside of the heart they are: the coronary arteries and the left and right pulmonary arteries.
Ischemic strokes occur due to blood vessels becoming blocked while hemorrhagic strokes are the result of broken blood vessels in or near the brain.
