This blockage deprives your heart muscle – or myocardium – of blood and oxygen. If blood flow is not restored to your heart muscle within 20-40 minutes, irreversible death of the muscle will begin to occur. Muscle continues to die for 6-8 hours, at which time your heart attack will be described as ‘complete’.  Depending on how much heart muscle is damaged, disability or death can result.

But if you actually do live through this, your dead heart muscle will eventually be replaced by scar tissue. So as you can imagine, every minute counts.
