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.
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
Ischemia is a medical term meaning insufficient oxygen ... usually caused by insufficient blood flow. If the ischemia is occurring in the heart it will probably cause some type of cardiac problem: anything from mild cardiac failure (not pumping all the blood that the body demands) to pain (angina) to death of some or all of the cardiac muscle (a heart attack).
Focal cerebral ischemia (FCI) is often results from a blood clot in the brain. The blood flow in the affected area is reduced. The reduction could be severe or mild but usually FCI causes irreversible injury to sensitive neurons.
ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
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.

irreversible ischemia
a decrease in bloodflow to the brain due to narrowing of the arteries
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 small reversible defect in the inferoseptal wall of mild intensity typically indicates a transient reduction in blood flow or perfusion to that area of the heart muscle, often due to temporary ischemia. This finding may be observed during imaging studies such as a stress test or a cardiac MRI. It suggests that the affected area can recover function, especially if the underlying cause, like coronary artery disease, is addressed. Regular monitoring and appropriate management are recommended to prevent further complications.
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.
Symptoms of intestinal ischemia include sudden abdominal pain. The pain can range from mild to severe. A sudden needs to use the bathroom, frequent and forceful stools, tenderness in the abdomen, bloody stools, vomiting and fever.

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.
