　　Broken heart syndrome can happen in response to shocking or suddenly emotional events both positive ones like winning the lottery, or negative ones like a car accident or the unexpected death of a loved one. A flood of stress hormones and adrenaline causes part of the heart to enlarge temporarily and triggers symptoms that can look like heart attack: chest pain, shortness of breath, irregular heart rhythm. The difference is that the factors that would normally cause heart attack, such as a blocked artery, arent present.

　　Most sufferers usually recover within a week or two, but in rare cases about 1% people die of the condition.

　　Doctors have long known about broken heart syndrome first described by Japanese researchers two decades ago and that it seemed to occur mostly in women. So, Dr. Abhishek Deshmukh, a cardiologist at the University of Arkansas who has treated women with broken heart syndrome, became curious about just how gender-specific the condition was.

　　Using a federal database that included data from roughly 1,000 hospitals, Deshmukh found 6,229 cases of broken heart syndrome in 2007. Of those, only 671 just under 11% were in men. He found that, overall, women had about 7.5 times the risk of broken heart syndrome as men; in people under 55, women were at 9.5 times greater risk than men. Women over 55 were also three times more likely to suffer broken heart syndrome than younger women.
