Heartbeats Reveal Heartbreak

That old saying, "she died of a broken heart?" It's not just poetry. Studies have shown that some people who lose a loved one may be at greater risk for a heart attack or cardiac death. And new research, presented this week at the American Heart Association's Scientific Sessions, offers clues for why. [Thomas Buckley et al., "Early Bereavement is Associated with Increased Heart Rate and Reduced Heart Rate Variability"]

常聽說：某某心碎而亡。這可不僅僅是為了增添詩意，研究發(fā)現(xiàn)，失去摯愛的人更容易心臟病發(fā)作或猝死。美國心臟協(xié)會科學年會上發(fā)布的一項新的研究中闡明了原因。

The subjects in the study included 78 volunteers who'd recently lost a spouse or child at a hospital, and a control group whose relatives survived the hospital stay. The average age of both groups was about 65. Researchers monitored the participants’ heart rates and rhythms for 24 hours, once within two weeks of the family death and again six months later.

研究對象包括一組由78名剛剛失去配偶或孩子的群眾組成的實驗組，以及由親人有幸渡過難關的群眾組成的對照組。兩組研究對象的平均年齡均在65歲左右。在實驗組成員失去家人的兩星期之內(nèi)以及6個月之后，研究人員對兩組成員的心跳頻率和節(jié)奏各進行了一次24小時的監(jiān)控。

Soon after their loss the bereaved had an average heart rate of 75 beats per minute, five beats more than the controls. And twice as many episodes of tachycardia: rapid heartbeats. They also scored higher on depression and anxiety tests, as you'd expect, which could be behind the physiological changes.

剛經(jīng)歷喪偶或喪子之痛的實驗組成員心率為75次/分，比對照組成員高出5次/分；心動過速發(fā)作次數(shù)也是對照組的兩倍；在抑郁焦慮癥測試中得分也較高（分數(shù)越高，癥狀越嚴重）。可想而知，這一系列的生理變化意味著什么。

The good news: after six months, heart rates and rhythms were back to normal. But if you've just lost someone and feel physical heartache, the researchers recommend seeing a doctor. It could save someone else from grieving.

好在六個月之后，實驗組成員的心跳頻率和節(jié)奏就恢復正常了。但假如你剛失去摯愛又覺得心痛難耐的話，最好還是去看看醫(yī)生吧，別再讓你的家人為你傷心欲絕了。
