Cardiovascular diseases are the leading cause of death in Switzerland. In the event of a heart attack, swift action must be taken to increase the chances of survival and to minimise permanent damage to the heart. But what are the symptoms of a heart attack and how should a person react?

What is it?

What is a heart attack? 

Arteries that supply blood to the heart muscle are called coronary arteries. During a heart attack, blood clots cause a blockage in one or more of these coronary arteries. This cuts off sufficient blood supply to the heart muscle, resulting in damage to the heart tissue. How much damage the heart sustains depends on how long it takes to restore the blood supply and which arteries are blocked.
