Cellular ischemia occurs when perfusion (oxygenation of the body and tissues) decreases. Because of the lack of blood flow through the capillaries the metabolism goes from aerobic (with oxygen) to anaerobic (without oxygen) which causes metabolic acidosis. The blood stagnates in the capillaries and lactic acid builds up due to the pre-capillary sphincter relaxing. Also the vasomotor center fails and the carbon dioxide level increases. Because the post-capillary sphincters stay constricted the capillaries are enlarged with fluid. On and on the end result is a drop in cardiac output.
What else can I help you with?
Is inferolateral ischemia curable?
Ischemia of any type is reversible. If ischemia is prolonged, it can turn to injury or infarction (in the case of the heart) and cell death, at which time it is not reversible or curable. There are studies with stem cells ongoing to attempt to regrow cardiac cells in heart attack scars, however, so this may not be a permanent condition forever.
What is ischemic heart tissue?
Ischemia occurs when there is not enough oxygenated blood reaching the cardiac muscle cells.
What is the difference between necrosis and ischemia?
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.
How do you use ischemia in a sentence?
ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
How do you describe symptomatic ischemia?
Symptomatic ischemia is characterized by chest pain called angina pectoris.

What is the term for decreased blood flow?
Ischemia is the medical term for decreased blood flow. Ischemia limits the supply of oxygen to tissues.
Is ischemia caused by seroquel?
Ischemia is not a direct side effect of Seroquel (quetiapine), an atypical antipsychotic medication. However, Seroquel can cause metabolic side effects, such as weight gain and changes in lipid levels, which may increase the risk of cardiovascular issues over time. If you have concerns about ischemia or side effects related to Seroquel, it's important to discuss them with a healthcare professional.
What is recommended treatment for anterior wall ischemia -?

What is the accented syllable for Ischemia?
The accented syllable in "Ischemia" is the second syllable: is-CHE-mia.
What is the accented syllable in the word ischemia?
The accented syllable in the word "ischemia" is "sche".
What is the definition of ischemia?
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.
