问答题I had always assumed a broken heart was just a metaphor, a cliché of country music and romance novels. So I was as surprised as anyone to learn last week that doctors now consider it a real medical event, one that can kill.【】The news comes from a report published in the New England, Journal of Medicine, in which physicians at Johns Hopkins described a group of 18 mostly older women and one man who developed serious heart problems after experiencing a sudden emotional shock, such as the death of a loved one, or, in the case of one 60-year-old woman, a surprise birthday party.【】What surprised the doctors who examined these patients was that none of them had actually suffered a heart attack. Indeed, few had any signs of heart disease at all. Yet at least five of the 19--and perhaps more--would have died without treatment, according to Dr. Ilan Wittstein, the cardiologist who led the study.
