Heart attacks. If your arteries become completely blocked, it can cause a heart attack (myocardial infarction). Heart attacks can permanently damage the heart muscle and, if not treated straight away, can be fatal. Dial 999 for immediate medical assistence if you think you're having a heart attack.
