infarction
Blood supply cutoff
Infarction is the death of tissue due to loss of blood supply, typically from a blocked artery.
A myocardial infarction is a heart attack—heart muscle dies when coronary arteries become obstructed.
A cerebral infarction is a stroke affecting brain tissue.
The term is medical and technical: The scan revealed evidence of a prior infarction.
