Ischemia vs. Infarction: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 4, 2023
Ischemia is the reduction of blood supply to tissues, while infarction is the death of tissues due to lack of blood supply.

Key Differences

Ischemia and infarction are medical terms that pertain to the flow of blood and the health of tissues. Ischemia refers to the situation where there's a reduced supply of blood to a part of the body, often caused by a blockage. Infarction, on the other hand, denotes the death of tissue due to a prolonged lack of blood supply, often resulting from sustained ischemia.

In the context of heart health, ischemia can result in symptoms like chest pain or discomfort because the heart muscle isn't getting enough oxygen-rich blood. However, if the blood flow isn't restored promptly, infarction, or a heart attack, can occur, indicating that a portion of the heart muscle has died. Similarly, in the brain, ischemia can lead to transient symptoms, but prolonged blockage can result in an infarction, commonly known as a stroke.

Ischemia can be temporary and reversible. It's a warning sign that a certain area isn't getting enough blood, and if addressed promptly, it might not lead to permanent damage. Infarction, however, means damage has been done. Once tissue undergoes infarction, it can't be revived; it's dead and lost its function.

Both ischemia and infarction can be detected through medical tests. While ischemia might be indicated by symptoms and changes in a person's electrocardiogram (ECG), infarction often results in specific markers in the blood, showing tissue damage, and might be visible on imaging studies like MRIs or CT scans.
