heart attack

Definition: a cardiac event where one or more blood vessels in the heart become blocked, cutting off the flow of oxygenated blood to part of the heart muscle. If not corrected quickly, the affected heart muscle will die and be replaced by scar tissue.

in most cases, the heart destroying blockage is, obviously, something internal to the affected blood vessel.

sometimes, the heart destroying blockage can be completely external to the body.
