文字稿

There’s a biological clock keeping time inside all of us. It's the reason we want to sleep at night, but it also drives huge changes in the way our body works including in our heart muscle.

This is lifesaving open-heart surgery. The operation puts the heart under huge stress and the study in Lille in France suggests the body clock also influences our recovery.

The study on five hundred patients showed the risk of complications, including heart attacks, halved from 18 percent in morning operations to just nine percent in the afternoon.

The researchers said patients should not be frightened away from vital surgery. They want to do more studies, but think high-risk patients might benefit from being moved to the afternoon.

This study shows the potential of doing medicine in time with the body clock and the researchers are now investigating other types of surgery.

每個(gè)人體內(nèi)都有一個(gè)準(zhǔn)時(shí)的生物鐘。這個(gè)生理時(shí)鐘正是我們一到晚上就想睡覺(jué)的原因，但它還會(huì)導(dǎo)致包括心肌等各身體部位的運(yùn)作方式發(fā)生巨大的改變。

這是能挽救生命的心內(nèi)直視術(shù)。該手術(shù)會(huì)給心臟帶來(lái)巨大的負(fù)擔(dān)，而這項(xiàng)在法國(guó)里爾所做的研究表明，人體生物鐘也會(huì)影響術(shù)后的恢復(fù)情況。

該研究分析了五百位患者的病例，其結(jié)果顯示，在上午接受手術(shù)的病人患包括心臟病發(fā)作等并發(fā)癥的風(fēng)險(xiǎn)是18%，而下午手術(shù)的病人所面臨的風(fēng)險(xiǎn)僅為9%，降低了一半。

這些研究人員說(shuō)，患者們不應(yīng)因此被嚇到而拒絕接受重要的手術(shù)。研究人員想做進(jìn)一步的研究，但他們認(rèn)為，對(duì)高危患者來(lái)說(shuō)，把手術(shù)挪到午后做更好。 

該研究顯示了根據(jù)人體的生理節(jié)奏來(lái)決定治療病人的時(shí)間潛在的好處。這些研究者們正在調(diào)查其它類(lèi)型的手術(shù)與生物鐘之間的聯(lián)系。
