A heart attack can strike at any time and without warning. In minutes it can irreparably damage our hardest working muscle - the heart. And for many, a heart attack is the first sign of heart disease - the world's number one killer.

The program examines the causes behind the growing epidemic and what the world's leading scientists are doing to fight it.
