What happens when you have coronary heart disease?

  • The coronary arteries narrow because of a build-up of fatty deposits.
  • This reduces blood flow and leads to a lack of oxygen being supplied to the heart muscle.

Analogy: a tunnel

  • Imagine people carrying wood to a fire through a tunnel.
    • If the tunnel narrows, fewer people can fit through the tunnel.
  • This means that the fire will start to die out as less wood can reach it.
