Ischemia

Definition

Ischemia is a condition where there is insufficient blood flow to tissues, leading to a shortage of oxygen and nutrients necessary for cellular function. This can result from blockage or narrowing of blood vessels, affecting the cardiovascular system's ability to maintain adequate circulation.

Related terms

Hypoxia: A condition in which tissues are deprived of an adequate supply of oxygen, often a consequence of ischemia.

Angiogenesis: The process through which new blood vessels form from pre-existing vessels, potentially compensating for reduced blood flow due to ischemia.

Atherosclerosis: A disease characterized by the buildup of plaque inside arteries, which can lead to narrowing and blockage of the vessels and contribute to ischemia
