What happens to heart after death?

People can be brain dead, or they die because the heart and blood flow stop. The latter is what they now call “circulatory death.” But by the time it stops on its own, a person’s heart is starved of oxygen and the muscle cells are already dying. Left at body temperature, the damage, called ischemia, progresses rapidly.
