Which condition is characterized by area damage due to lack of blood flow, often leading to tissue death?

Infarction is characterized by the damage to an area of tissue due to a lack of blood flow, which results in cell death. This process typically occurs when an obstruction, such as a blood clot in a vessel, prevents sufficient blood from reaching a specific part of the body. The lack of blood flow means that oxygen and essential nutrients cannot adequately reach the affected tissues, leading to infarction.

Ischemia, while closely related, refers more broadly to insufficient blood flow to an area, which may not always lead to tissue death. Congestion refers to an excess of blood in a part of the body, often due to impaired return of blood from that area, and does not necessarily imply tissue death. Hypoxia indicates a lack of oxygen in the tissues but does not detail the underlying cause of blood flow restriction that leads to cell death, which is where infarction plays a crucial role. Therefore, infarction specifically captures the eventual consequence of ischemia when blood flow is sufficiently compromised.
