研究表明:失眠会增加患心脏病几率

 

《每日科学》(2011.10.24

 

你有失眠的困扰吗?如果你的回答是“是”的话,那么根据美国心脏协会的研究报道,你将比其他人更容易患上心脏病。

 

最新研究表明,失眠患者患心脏病的几率比睡眠良好的人群要高出27%45%。研究人员把失眠症状分为三类,以下是研究结果:

连续一个月几乎每天都很难入睡的,患心脏病的几率比常人高出45%;连续一个月几乎每天都不能熟睡、睡眠较浅的,患心脏病的几率比常人高出30%;超过一周每天早上醒来无精打采、非常疲倦的,患心脏病的几率比常人高出27%

 

“失眠问题很常见,也容易治疗”,来自挪威大学公共健康学院科技系的研究员拉尔斯.埃里克.兰珊德教授如是说,“所以认识到失眠与心脏疾病之间的关系非常重要,如果有这些症状,一定要告诉医生。”

 

患心脏病的概率也会随着每一样症状的严重程度而升高。这项调查基于1995年至1997年在挪威进行的全民健康调查。52610名挪威成年人参与了其中关于失眠的问卷调查。研究人员检查了医院档案记录和死因登记记录确定了有2368人在接下来的11年内初次爆发了心脏病。

 

研究人员用生存分析法来调整其它因素可能带来的影响,如年龄、性别、婚姻状况、教育程度、血压、胆固醇、糖尿病、体重、运动量、倒班等。还考虑到焦虑、抑郁因素,它们同样会导致失眠。

 

之前有一些小型的研究将失眠与心脏疾病联系在一起,包括高血压和心脏病。研究发现,高达33%的人出现了至少一种失眠的症状。在美国,每年都有新增心脏病人785000名。失眠与心脏疾病之间究竟有什么样的关系目前尚不明确。有人认为,是因为睡眠问题对一些会引起心脏疾病的因素有影响,如高血压和炎症。

 

研究对阻塞性睡眠呼吸暂停综合症不适用,并且研究结果也不适应美国人,因为他们的白天和夜间生活都和挪威人不一样。兰珊德教授说,为了得出更为全面精确的答案,还需做进一步的研究。

Insomnia Could Moderately Raise Your Heart Attack Risk, Study Suggests

 

 

ScienceDaily (Oct. 24, 2011) — Having trouble sleeping? If so, you could have a moderately higher risk of having a heart attack, according to research reported in Circulation: Journal of the American Heart Association.

 

In a recent study, the risk of heart attack in people with insomnia ranged from 27 percent to 45 percent greater than for people who rarely experienced trouble sleeping. Researchers related heart attack risks to three major insomnia symptoms. Compared to people who reported never or almost never having these problems, people who: had trouble falling asleep almost daily in the last month had a 45 percent higher heart attack risk; had problems staying asleep almost every night in the last month had a 30 percent higher heart attack risk; didn’t wake up feeling refreshed in the morning more than once a week had a 27 percent higher heart attack risk.

 

"Sleep problems are common and fairly easy to treat," said Lars Erik Laugsand, M.D., lead researcher and internist from the Norwegian University of Science and Technology Department of Public Health in Trondheim. "So it's important that people are aware of this connection between insomnia and heart attack and talk to their doctor if they're having symptoms."

 

Heart attack risk also increases with each additional insomnia symptom, researchers said. The study was based on 52,610 Norwegian adults who answered questions about insomnia as part of a national health survey in 1995-97. 52610 Researchers examined hospital records and Norway's National Cause of Death Registry to identify 2,368 people who had first-time heart attacks during the following 11 years.

 

The researchers used survival analysis to adjust for factors that could influence the results such as age, sex, marital status, education level, blood pressure, cholesterol, diabetes, weight, exercise and shift work. They also considered depression and anxiety, both of which can cause insomnia.

 

Up to 33 percent of people in the general population experience at least one insomnia symptom, according to researchers. Previous smaller studies have linked insomnia to heart disease, including high blood pressure and heart attacks. Every year, about 785,000 Americans have a first-time heart attack.

It's unclear why insomnia is linked to higher heart attack risk. Some suggest sleep problems affect heart attack risk factors such as high blood pressure and inflammation.

 

Researchers didn't adjust for obstructive sleep apnea, and results may not apply to Americans because their daylight hours and sleep patterns differ from Norwegians, said Laugsand, noting that further study is needed.
