What is an infarction?
infarction, death of tissue resulting from a failure of blood supply, commonly due to obstruction of a blood vessel by a blood clot or narrowing of the blood-vessel channel. The dead tissue is called an infarct.
What causes an infarction?
A heart attack (medically known as a myocardial infarction) is a deadly medical emergency where your heart muscle begins to die because it isn’t getting enough blood flow. This is usually caused by a blockage in the arteries that supply blood to your heart.
Is an infarction a stroke?
Infarction or Ischaemic stroke are both names for a stroke caused by a blockage in a blood vessel in the brain. This is the most common type of stroke.
What is infarction of the brain?
Brain infarction occurs when the blood within the arterial wall dissects into the arterial lumen and embolizes intracranially.
What happens in an infarction?
A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is blocked.
Why do healthy people have heart attacks?
Seemingly healthy people are “suddenly” having heart attacks because, as it turns out, their arteries are not perfectly healthy and they don’t know it. With the proper noninvasive tests, these diseased arteries would have been identified, and the heart attacks wouldn’t have happened.
What happens when a stroke occurs?
A stroke happens when a blood clot blocks blood flow to the brain. This causes brain tissue to become damaged or die. A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts.
Are ischemia and infarction the same?
Both terms, ischemia and infarction, are used here. Ischemia denotes diminished volume of perfusion, while infarction is the cellular response to lack of perfusion.
What does infarction do to the brain?
Also called ischemic stroke, a cerebral infarction occurs as a result of disrupted blood flow to the brain due to problems with the blood vessels that supply it. A lack of adequate blood supply to brain cells deprives them of oxygen and vital nutrients which can cause parts of the brain to die off.
Can infarct be cured?
Can stroke be cured? The short answer is yes, stroke can be cured — but it occurs in two stages. First, doctors administer specific treatment to restore normal blood flow in the brain. Then, the patient participates in rehabilitation to cure the secondary effects.
