When there has been a loss of blood supply in the heart muscle and blood get clot in coronary arteries then the patient experiences a heart attack. There are many causes of heart attack, one of them is blocked coronary arteries and other is a spasm of a coronary artery that shuts down blood flow to part of the heart muscle.

What about if our arteries and blood vessel are all smooth and not block whether it means that we will not suffer heart attack?
