- Ischemic stroke is the death of or injury to brain cells caused when a blood clot or other particle (such as a fatty plaque) blocks an artery deep within the brain (cerebral artery) or leading to it, such as the carotid (neck) artery.

ischemia myocardial ischemia, a condition of insufficient blood flow to the heart muscle via the coronary arteries, often resulting in chest pain (angina pectoris). In diagnostic imaging, thallium-201 or other substances are injected into the blood to reveal areas of myocardial ischemia. deficiency of blood supply to the heart muscle, due to obstruction or constriction of the coronary arteries. renal ischemia. severe or prolonged ischemia causes irreversible renal failure and death from uremia.

Ischemia - Topic Overview Ischemia is the medical term for what happens when your heart muscle doesn't get enough oxygen. Ischemia usually happens because of a shortage of blood and oxygen to the heart muscle.It is usually caused by a narrowing or blockage of one or more of the coronary arteries (which supply blood to the heart muscle).In many cases ischemia is a temporary problem.t is usually caused by a narrowing or blockage of one or more of the coronary arteries (which supply blood to the heart muscle).

Molecular and Cellular Mechanisms of Ischemia-Induced Neuronal Death Focal ischemia or cerebral infarction is the condition or state in which a specific area of brain tissue undergoes injury as a consequence of a temporary or permanent obstruction of local blood supply. Focal ischemia results in death of both neurons and nonneuronal cells in contiguous areas of brain, usually representing a single vascular territory.

Myocardial Ischemia - Nuclear Medicine and Risk Stratification Myocardial ischemia is a disorder that usually is caused by a critical coronary artery obstruction, which is also known as atherosclerotic coronary artery disease (CAD). CAD is the leading cause of death worldwide, and it is the second most common cause of emergency department visits in the United States.

Silent Ischemia and Ischemic Heart Disease Silent Ischemia and Ischemic Heart Disease. What is ischemia? Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is the name for decreased blood flow and oxygen to the heart muscle. What is ischemic heart disease? It's the term given to heart problems caused by narrowed heart arteries.

Transient ischemic attack A transient ischemic attack is a brief episode of neurological dysfunction caused by loss of blood flow in the brain, spinal cord, or retina, without tissue death. TIAs have the same underlying mechanism as ischemic strokes. Both are caused by a disruption in blood flow to the brain, or cerebral blood flow. The definition of TIA was classically based on duration of neurological symptoms. The current widely-accepted definition is called tissue-based because it is based on imaging, not time. The

Ischemic Cardiomyopathy: Symptoms, Causes, and Treatment Ischemic cardiomyopathy (IC) is a condition when your heart muscle is weakened as a result of a heart attack or coronary artery disease. In coronary artery disease, the arteries that supply blood to your heart muscle become narrowed. This can keep necessary blood from reaching portions of your heart muscle, causing damage. If you develop IC, the left ventricle in your heart will likely become enlarged, dilated, and weakened.

- humane (comparative humaner or more humane, superlative humanest or most humane) 1  Having or showing concern for the pain or suffering of another; compassionate. It is no longer considered humane to perform vivisection on research animals. As methods of execution go, beheading is more humane than drawing and quartering.

ischemia Ischemia can also occur in the arteries of the brain, where blockages can lead to a stroke. About 80-85% of all strokes are ischemic. Most blockages in the cerebral arteries are due to a blood clot, often in an artery narrowed by plaque. Sometimes, a blood clot in the heart or aorta travels to a cerebral artery.

Ischemic Stroke Ischemic (“is-skeem-ic”) stroke occurs when an artery to the brain is blocked. The brain depends on its arteries to bring fresh blood from the heart and lungs. The blood carries oxygen and nutrients to the brain, and takes away carbon dioxide and cellular waste.

Ischemia Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue. It also means local anemia in a given part of a body sometimes resulting from congestion (such as vasoconstriction, thrombosis or embolism).rain ischemia is insufficient blood flow to the brain, and can be acute or chronic. Acute ischemic stroke is a neurologic emergency that may be reversible if treated rapidly. Chronic ischemia of the brain may result in a form of dementia called vascular dementia.

Overview Treatment for myocardial ischemia involves improving blood flow to the heart muscle. Treatment may include medications, a procedure to open blocked arteries or bypass surgery.yocardial ischemia, also called cardiac ischemia, can damage your heart muscle, reducing its ability to pump efficiently. A sudden, severe blockage of a coronary artery can lead to a heart attack.

About Cerebral Ischemia Cerebral Ischemia. Cerebral ischemia or brain ischemia, is a condition that occurs when there isn’t enough blood flow to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke.

- Myocardial ischemia is the primary manifestation of congenital or acquired coronary artery disease (CAD). In Coronary Artery Anomalies, Angelini comprehensively classifies coronary anomalies in (normal) human hearts, as follows: Anomalies of origination and course. Anomalies of intrinsic coronary arterial anatomy.

- Ischemia is a symptom in which a person does not have enough blood supply to a part of the body, making that part of the body ischemic. For example, in a heart attack, a coronary artery is blocked so blood cannot get to the heart muscle beyond the blockage point.

Silent Ischemia and Ischemic Heart Disease When arteries are narrowed, less blood and oxygen reaches the heart muscle. This is also called coronary artery disease and coronary heart disease. This can ultimately lead to heart attack. Ischemia often causes chest pain or discomfort known as angina pectoris.
