Fearing a heart problem, we got various tests done and the treadmill stress test reported: normal B response, no chest pain, good effort tolerance but the test was positive for inducible NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. Ischemia is a term used for an inadequate blood supply feeding Oxygen to a given area of tissue. Reversible ischemia is when intervention, in the form of medication, stenting or bypass can increase that supply. Irreversible is when there is nothing available to assist with the blood flow. A stress test that is consistent with inducible ischemia is a diagnostic tool. It predicts with approximately 75- 90% sensitivity and specificity if a patient with an intermediate risk for coronary artery blockages has blockages of greater than 70% in major arteries.

When the heart is put under stress, such as the treadmill test, the demand for oxygen by the heart is greater than the supply that it is receiving. Treatment depends on multiple variables which you should discuss with your cardiologist. 2015-08-01 2010-04-01 Insufficient blood flow to meet the needs of the heart produced by tachycardia and relative hypotension rather than by flow-limiting blockages within the coronary arteries. Demand ischemia may occur in atrial fibrillation with a rapid ventricular response; in hypotension or hypovolemia; or in sepsis or the systemic inflammatory response syndrome.

2021-01-18 · Ischemia is any reduction in blood flow resulting in decreased oxygen and nutrient supplies to a tissue. Ischemia may be reversible, in which case the affected tissue will recover if blood flow is restored, or it may be irreversible, resulting in tissue death.

Ischemia is the reduced blood flow to your heart, causing it to not be able to get oxygenated properly. The reduced blood flow can cause damage to your heart muscle, making its pump weaker. This reduced blood flow is usually caused by a blocked artery or partially blocked artery, also known as Coronary artery disease. Ischemia is generally due to issues with the blood vessels where there is some form of obstruction.
