simply, Hypoxia is less oxygen supply to cell tissues, while the Ischemia is less blood supply to cell issues.
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.
what is reversible vs irreversible ischemia in the brain
A decreased supply of oxygen to tissue is known as hypoxia.
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.
Renal ischemia /hypoxia: blood deficiency in the kidney caused by a constriction or obstruction of its blood vessels, or oxygen concentration below physiological levels.
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
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."
Deficient blood supply means not enough blood; this happens if there is a problem with the circulation, which could be caused by a blood clot inside a blood vessle, or pressure on a vessle, or a severed blood vessle, or arteriosclerosis.
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).
