Definition

Inadequate blood supply to tissues or organs, essentially a localized shipping crisis where oxygen deliveries are critically delayed. Left unchecked, it leads to tissue death and very bad outcomes.

Example Usage

The cardiologist explained that cardiac ischemia was causing his chest painā€”his heart muscle was literally suffocating from lack of blood flow.

Origin

From Greek 'iskhein' (to restrain) and 'haima' (blood)

Fun Fact

The brain can only tolerate ischemia for about 3-6 minutes before permanent damage occurs, giving stroke treatment a terrifyingly narrow therapeutic window.
