Poor sleep linked to heart failure: Norwegian study 睡不好與心臟衰竭有關:挪威研究

People who have trouble drifting off to sleep may be at increased risk of heart failure, researchers say. The study followed more than 50,000 people for 11 years. Scientists found those who suffered several nights of poor sleep were more likely to develop the condition, in which the heart fails to pump properly.

Scientists at the Norwegian University of Science and Technology looked at more than 50,000 people aged between 20 and 89. At the beginning of the study, none of them were known to have heart failure.

In this condition the muscles of the heart are often too out of shape to do their job properly — they may be too weak or too stiff to pump blood around the body at the right pressure. People with the disorder may feel increasingly breathless and exhausted.

And as heart failure worsens, it can be difficult to get a full night’s rest - but the Norwegian study is one of few to investigate whether poor sleepers without the condition are at risk of getting it in later life.

難以進入夢鄉者心臟衰竭風險可能較高,研究人員說。這份研究追蹤五萬多人長達十一年。科學家發現,那些晚上睡不好的人,比較可能出現這種心臟無法正常跳動的疾病。

挪威科技大學科學家研究年齡在二十到八十九歲的五萬多人。研究之初,這些人都沒有心臟衰竭。

心臟疾病患者的心肌往往嚴重變形,以至於無法正常運作,它們可能太衰弱或太僵硬,無法以適當的壓力將血液送到身體四處。有這種疾病者,可能會越來越覺得無法呼吸與精疲力竭。

而且隨著心臟衰竭加劇,可能無法一夜好眠,但這份挪威研究是少數調查沒有心臟疾病但睡不好的人,生命後期是否有心臟衰竭之虞的研究之一。
