This topic referred about the amazing sudden death of the cardiovascular causes in the young peoples and how we can prevent this unhappy event? It is possible to existing a protocol or an ideal management in this way? We can control the phenomenon? How we can save many lives at young age? Starting from the mentality of the young people how if " I'm young and I'm healthy", I have performed this book to be an alarm signal for the young people in general and young professional athletes but also for the physicians who are required to have a very serious and responsible attitude in their medical daily practice. A young person is not necessarily healthy. This is the reason why I have decided to write this book, after many observations of real life cases, and because I think, as physicians, we can make something very important for these young people to prevent the sudden death at young age. We have to employ high efforts in our medical practice to decrease the mortality at young age.
