noun Pathology. a localized area of tissue, as in the heart or kidney, that is dying or dead, having been deprived of its blood supply because of an obstruction by embolism or thrombosis.View full answer
Keeping this in consideration, What are infarcts?
Share Give Feedback. External Websites. 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.
Hereof, What does infarction mean in Latin?. The word "infarction" comes from the Latin "infarcire" meaning "to plug up or cram." It refers to the clogging of the artery.

Infarct sentence example
This is due to intense engorgement of the vessels brought about through these minute existing collateral channels and results in a peripheral congested zone round the infarct . This necrosed area forms the pale infarct .
What is an infarct and what causes it?
Specialty. Pathology. Infarction is tissue death (necrosis) due to inadequate blood supply to the affected area. It may be caused by artery blockages, rupture, mechanical compression, or vasoconstriction. The resulting lesion is referred to as an infarct (from the Latin infarctus, "stuffed into").
Ischemia denotes diminished volume of perfusion, while infarction is the cellular response to lack of perfusion.
An infarct is an area of necrosis (tissue death) due to the blood vessel blockage. Ischemic strokes include: Thrombotic stroke (cerebral thrombosis): This is the most common type of stroke. In a thrombotic stroke, a blood clot (thrombus) forms inside an artery in the brain, blocking blood flow.
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.
Several months after an acute ischaemic event the brain cells in the infarcted area have died leaving an area of low density.
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.
Intravenous recombinant tissue plasminogen activator (rt-PA) is indicated for patients with all clinical types of cerebral infarction within 3 hours after onset. Antiplatelet therapy, anticoagulant therapy, neuroprotectants comprise another choice.
ALTHOUGH CEREBRAL INFARCTION is a common cause of death in the United States, little is known about the actual mechanism of deaths during the immediate postinfarction period. Some authors have implicated acute brain swelling as a major con- tributor to death from cerebral infarction.
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. Blockages can be caused by a blood clot (Thrombosis) forming around fatty deposits in the blood vessels of the brain.
Fortunately, damaged brain cells are not beyond repair. They can regenerate — this process of creating new cells is called neurogenesis. The most rapid recovery usually occurs during the first three to four months after a stroke. However, recovery can continue well into the first and second year.

Silent cerebral infarction (SCI), or silent stroke, is a brain injury likely caused by a blood clot that interrupts blood flow in the brain. It's a risk factor for future strokes and a sign of progressive brain damage.
Stroke usually affects one side of the brain. Movement and sensation for one side of the body is controlled by the opposite side of the brain. This means that if your stroke affected the left side of your brain, you will have problems with the right side of your body.
A cerebral infarction (also known as a stroke) refers to damage to tissues in the brain due to a loss of oxygen to the area.
Troponins are the most widely recognized and important cardiac enzymes used in the diagnosis of acute myocardial ischemia in modern medicine. The majority of patients with an acute MI will have elevation in troponins within 2 to 3 hours of arrival at the emergency department, versus 6 to 12 hours with creatine kinase.
Treatment for myocardial ischemia involves improving blood flow to the heart muscle. Treatment may include medications, a procedure to open blocked arteries (angioplasty) or bypass surgery.
Symptoms of stable ischemic heart disease include angina, which is characteristic chest pain on exertion, and decreased exercise tolerance. Symptoms of myocardial infarction include acute chest pain, shortness of breath, nausea, vomiting, palpitations, sweating, and/or anxiety.
The signs of a stroke often appear suddenly, but that doesn't mean that you won't have time to act. Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke.
- Sudden NUMBNESS or weakness of face, arm, or leg, especially on one side of the body.
- Sudden CONFUSION, trouble speaking or understanding speech.
- Sudden TROUBLE SEEING in one or both eyes.
- Sudden TROUBLE WALKING, dizziness, loss of balance or coordination.
An IV injection of recombinant tissue plasminogen activator (tPA) — also called alteplase (Activase) — is the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm with the first three hours.
