Myocardial ischemia is an imbalance between myocardial oxygen supply and demand. Left untreated, it results in angina pectoris, myocardial stunning, myocardial hibernation, ischemic preconditioning, postconditioning, or under the most severe instances, acute coronary syndrome and myocardial infarction.
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 can also be acute, due to a sudden reduction in blood flow, or chronic, due to slowly decreasing blood flow.Ischemia can occur anywhere in the body. Heart attacks and strokes can both result from ischemia.schemia 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 can also be acute, due to a sudden reduction in blood flow, or chronic, due to slowly decreasing blood flow. Ischemia can occur anywhere in the body.
