ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
Symptomatic ischemia is characterized by chest pain called angina pectoris.
Silent ischemia usually is caused by emotional or mental stress or by exertion, but there are no symptoms.
necrosis is death of cells with underlying/ or death of cells that cause inflammation. necrosis has to have an underlying injury. ischemia is decreased blood supply to tissues/ cells due to obstruction/ constriction of vasculature - indeed, this is an injury, and can lead to necrosis of cells if not resolved quickly! Note that apoptosis is programmed cell death - i.e. nucleus control is involved, and there is no inflammation - it is clean cell death! this is awesome.
Inferoapical ischemia is lack of blood flow below the apex.
ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
There are four categories of cerebral hypoxia; in order of severity they are: diffuse cerebral hypoxia (DCH), focal cerebral ischemia, cerebral infarction, and global cerebral ischemia.
Ischemia is the medical term for decreased blood flow. Ischemia limits the supply of oxygen to tissues.
Ischemia=decreased oxygen/nutrients Infarction=no blood flow to the area ischemia can leads to infarction. ischemia means, reduced of blood supply to specific organ. while, infarction refers to death tissue.
The medical term for the reduction of oxygen supply to tissue is ischemia. This condition can lead to tissue damage or cell death if not promptly treated. Symptoms of ischemia can include pain, numbness, or tissue discoloration.
in myocadial ischemia, pain radiate to jaw, neck,shoulder,arm wheras in aortic dissection pain radiate to back, between scapulae there is differense between pulse rate of both arms and leg depending on ecg changes
Reversible ischemia occurs when blood flow is temporarily restricted to an area, but the tissue is not permanently damaged and can recover if blood flow is restored quickly. Irreversible ischemia, on the other hand, results in permanent tissue damage due to prolonged lack of blood supply, leading to cell death and potentially organ dysfunction.
Ischemia is a medical condition characterised by a restriction of blood into tissues which causes a shortage of glucose and oxygen needed to keep cells alive and healthy. This lack of oxygen can lead to Hypoxia and Cyanosis (blueing of the skin). There are a number of causes of Ischemia, some of which include Hypoglycemia, Atherosclerosis, Hypotension, Sickle Cell Disease, and Anemia.
A drop in blood flow, or blood pressure, is known as hypotension. Other terms can be used to describe the specific lack of blood flow, such as "ischemia," and "hypoxia."
Renal ischemia refers to inadequate blood flow to the kidneys, which can result in reduced oxygen and nutrient delivery to the kidney tissues. This condition can lead to kidney damage and impaired kidney function if not addressed promptly. Causes of renal ischemia can include blockages in blood vessels or decreased blood flow due to conditions like atherosclerosis.
An arheroma is a plaque made from cholesterol. When it breaks off it forms a clot in the blood stream. If this clot clogs an artery that feeds the heart muscle, it can cause ischemia (tissue hypoxia) or infarction (tissue death).
Hypoxia can occur in healthy people when they ascend to high altitudes.
