Broken heart syndrome, a life-threatening condition whose symptoms mimic a heart attack, is on the upswing, according to new research that shows the sharpest increases among women 50 and older.
Published in the Journal of the American Heart Association, the study examined 135,463 cases of broken heart syndrome in U.S. hospitals from 2006 to 2017. It found a steady annual increase among both women and men, with women making up 88.3% of the cases.

The overall increase wasn’t unexpected as the condition has become increasingly recognized among medical professionals, said Dr. Susan Cheng, the study’s senior author. But researchers were taken aback to find the rate of the condition was at least six to 12 times higher in women ages 50 to 74 than it was in men or in younger women.
“These skyrocketing rates are both intriguing and concerning,” said Cheng, director of the Institute for Research on Healthy Aging in the department of cardiology at the Smidt Heart Institute at Cedars-Sinai in Los Angeles.
The condition, also known as Takotsubo cardiomyopathy, has been studied for decades in Japan and elsewhere. But it wasn’t well known internationally until 2005, when the New England Journal of Medicine published research on it.
