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.

每個人體內都有一個准時的生物鐘。這個生理時鐘正是我們一到晚上就想睡覺的原因,但它還會導致包括心肌等各身體部位的運作方式發生巨大的改變。

這是能挽救生命的心內直視術。該手術會給心臟帶來巨大的負擔,而這項在法國里爾所做的研究表明,人體生物鐘也會影響術後的恢複情況。

該研究分析了五百位患者的病例,其結果顯示,在上午接受手術的病人患包括心臟病發作等並發症的風險是18%,而下午手術的病人所面臨的風險僅為9%,降低了一半。

這些研究人員說,患者們不應因此被嚇到而拒絕接受重要的手術。研究人員想做進一步的研究,但他們認為,對高危患者來說,把手術挪到午後做更好。 

該研究顯示了根據人體的生理節奏來決定治療病人的時間潛在的好處。這些研究者們正在調查其它類型的手術與生物鐘之間的聯系。
