Is a broken heart deadly?

A sudden, traumatic event occurs leaving the heart stunned and leaving the aggrieved with chest pain and shortness of breath. Doctor's call this "broken heart syndrome".

It sounds like a heart attack, but not exactly. Unlike a heart attack, broken heart syndrome is reversible and doesn't cause permanent heart damage. But if it's left untreated, a heart malfunction can lead to complications and even death.

Humans are not the only ones who suffer from a broken heart. Animals feel the pain too. Mary G is a dolphin, who was nursed back to health by trainer Tamara Monti. Mary G was in danger of dying from a broken heart when Monti didn't return to work after being stabbed to death by a neighbor.
