New studies reveal that heartbreak isn’t just a metaphor; although rare, people really can suffer (and die) from broken-heart syndrome :
The mysterious malady mimics heart attacks, but appears to have little connection with coronary artery disease. Instead, it is typically triggered by acute emotion or physical trauma that releases a surge of adrenaline that overwhelms the heart. The effect is to freeze much of the left ventricle, the heart’s main pumping chamber, disrupting its ability to contract and effectively pump blood.
The phenomenon is a “concussion” of the heart, says Scott Sharkey, a cardiologist at Minneapolis Heart Institute. “It’s really a heart attack which is triggered by stress rather than by a blocked artery,” he says.
