The next time you hear that someone died of a broken heart, believe it.

It turns out, you can die from a heartache; it’s a condition called Takotsubo cardiomyopathy.

Dr. Suzanne Steinbaum, Director of Women’s Heart Health at Lenox Hill Hospital, explained on HuffPost Live exactly how “broken-heart syndrome” works.

“There is a disease called Takotsubo cardiomyopathy … this is really when someone has a lot of emotional stress. A lot of stress hormones are released within the body and what that does is it can actually lead to a disease which can stun the heart,” Dr. Steinbaum explained. “It looks like a heart attack but it’s actually the heart stops functioning.”
