Irreversible ischemia refers to tissue damage that occurs when blood flow is completely blocked for an extended period, leading to cell death. This can result in permanent tissue damage or organ dysfunction. Common causes include heart attacks and strokes.
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 the medical term for decreased blood flow. Ischemia limits the supply of oxygen to tissues.
A reversible inferolateral defect seen on a myocardial perfusion imaging scan typically indicates reduced blood flow to the inferior and lateral walls of the heart during stress, but this impairment is reversible with rest. It suggests the presence of ischemia in those regions and may indicate potential underlying coronary artery disease. Follow-up testing and evaluation by a healthcare provider is usually recommended to further assess the significance of this finding.

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.
irreversible ischemia
A proof that a particular problem cannot be solved, or irreversible, ischemia mean that Inadequate blood supply (circulation) to a local area due to blockage of the blood vessels to the area.
reversible ischemia
a term cardiologists use to indicate that a persons heart can be saved with an intervention before an event like a heart attack. the intervention is usually a stent or bypass, depending on the severity and vessels invloved.

Anterior wall ischemia
likely due to coronary artery vasospasm, which can result in transient ischemia. Nitroglycerin dilates coronary arteries, increasing blood flow to the affected area and relieving the spasm-induced wall motion abnormality. It is important to investigate the underlying cause of vasospasm and address any coronary artery disease risk factors.
what is the meaning of negative for provocable ischemia
The accented syllable in "Ischemia" is the second syllable: is-CHE-mia.
