Transcripción
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.
