What is Ischemic?

Answer 1

Ischemia is inadequate oxygenation of a body part. It is usually caused by a lack of blood flow.

Answer 2

Ischemia is a lack of oxygen to an organ or tissue. Usual causes are like others said, a blocked artery, but ischemia can also be caused by carbon monoxide poisoning, certain drugs displacing oxygen, certain drugs slowing your breathing, low iron, or illnesses such as emphysema.

Considering the context of the thread, ischemia would most likely be caused by a blockage of one or more of the coronary arteries. It is something that must be treated as soon as possible before tissue death results. Time is muscle.

Answer 3

It's the lack of blood and oxygen flow to the muscles in the heart...if caught early enough it can be reversed by drugs and surgical procedures before major damage is done and that part of the muscle dies which when this is happening it is called a myocardial infarction..aka a heart attack...

Answer 4

Definition:
Patients with this condition have weakened heart pumps, either due to previous heart attacks or due to current blockages of the coronary arteries. (There may be a build-up of cholesterol and other substances, called plaque, in the arteries that bring oxygen to heart muscle tissue).

The term "ischemic" means that an organ, in this case the heart muscle, has not received enough blood and oxygen. "Cardio" refers to the heart and "myopathy" means this is a muscle-related disease.

In summary, ischemic cardiomyopathy is a medical term that doctors use to describe patients who have congestive heart failure that is a result of coronary artery disease .

Answer 5

An ischemic stroke occurs when an artery in the brain becomes blocked.
What is it? 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. If an artery is blocked, the brain cells (neurons) cannot make enough energy and will eventaully stop working. If the artery remains blocked for more than a few minutes, the brain cells may die. This is why immediate medical treatment is absolutely critical.

What causes it? Ischemic stroke can be caused by several different kinds of diseases. The most common problem is narrowing of the arteries in the neck or head. This is most often caused atherosclerosis, or gradual cholesterol deposition. If the arteries become too narrow, blood cells may collect and form blood clots. These blood clots can block the artery where they are formed (thrombosis), or can dislodge and become trapped in arteries closer to the brain (embolism). Another cause of stroke is blood clots in the heart, which can occur as a result of irregular heartbeat (for example, atrial fibrillation), heart attack, or abnormalities of the heart valves. While these are the most common causes of ischemic stroke, there are many other possible causes. Examples include use of street drugs, traumatic injury to the blood vessels of the neck, or disorders of blood clotting.

Are there different kinds of ischemic stroke? Yes. Ischemic stroke can further be divided into two main types: thrombotic and embolic.

A thrombotic stroke occurs when diseased or damaged cerbral arteries become blocked by the formation of a blood clot within the brain. Clinically referred to as cerebral thrombosis or cerebral infarction, this type of event is responsible for almost 50% of all strokes. Cerebral thrombosis can also be divided into an additional two categories that correlate to the location of the blockage within the brain: large-vessel thrombosis and small-vessel thrombosis. Large-vessel thrombosis is the term used when the blockage is in one of the brain's larger blood-supplying arteries such as the carotid or middle cerebral, while small-vessel thrombosis involves one (or more) of the brain's smaller, yet deeper penetrating arteries. This latter type of stroke is also called a lacuner stroke.

An embolic stroke is also caused by a clot within an artery, but in this case the clot (or emboli) was formed somewhere other than in the brain itself. Often from the heart, these emboli will travel the bloodstream until they become lodged and can not travel any further. This naturally restricts the flow of blood to the brain and results in almost immediate physical and neurological deficits.


Deprived of oxygen and other nutrients, the brain suffers damage as a result of the stroke.
Who gets it? Ischemic stroke is by far the most common kind of stroke, accounting for about 88% of all strokes. Stroke can affect people of all ages, including children. Many people with ischemic strokes are older (60 or more years old), and the risk of stroke increases with older ages. At each age, stroke is more common in men than women, and it is more common among African-Americans than white Americans. Many people with stroke have other problems or conditions which put them at higher risk for stroke, such as high blood pressure (hypertension), heart disease, smoking, or diabetes.

Answer 6

In medicine, ischemia (Greek ισχαιμία, isch- is restriction, hema or haema is blood) is a restriction in blood supply, generally due to factors in the blood vessels, with resultant damage or dysfunction of tissue. It may also be spelled ischaemia or ischæmia.

Answer 7

What is ischemia?

Ischemia (is-KE'me-ah) is a condition in which the blood flow (and thus oxygen) is restricted to a part of the body. Cardiac ischemia is the name for lack of blood flow and oxygen to the heart muscle.

Answer 8

Ischaemia (is-ke'-mi-a) [Greek. ischein-to check; haima-blood]. Deficiency of blood in a part due to functional constriction or actual obstruction of a blood vessel.--ischaemic.(adjective).
Myocardial ischaemia- deficiency of blood supply to the heart muscle, due to obstruction or constriction of the coronary arteries.

Answer 9

The term "ischemic" means that an organ, in this case the heart muscle, has not received enough blood and oxygen.

Answer 10

Lack of blood flow to the area, usually a blockage of some sort.
