Ischaemia

In medicine, ischaemia is when the blood supply is blocked or restricted. This is usually caused by problems in the blood vessels, and causes damage to the body.[1] It may also be spelled ischemia or ischæmia. It comes from the Greek words, isch- to restrict and hema or haema meaning blood.

Ischaemic heart disease (Coronary heart disease) is the world’s biggest killer, responsible for 16% of the world’s total deaths. Since 2000, the largest increase in deaths has been for this disease, rising by more than 2 million to 8.9 million deaths in 2019[2].

When a part of the body isn't getting enough oxygen-rich blood, the skin sometimes becomes pale or turn blue. When the heart doesn't get blood it turns white.
