Chronobiology international:注意!晚睡、晚起或睡眠不足,均与更高的急性心肌梗死风险相关

2021-10-18 “ 心关注”公众号 “ 心关注”公众号

土耳其学者发表在《Chronobiology international》杂志上的小样本量研究,有关注到不同睡眠类型人群,急性心肌梗死(AMI)的发病时间段存在明显差异。

一般来说,成年人每晚睡7-9小时最为合适。然而,工作压力大、睡前反复刷手机等导致个人睡眠不足,在生活中也越来越普遍,而睡眠不足又会损害身体与心理健康。

睡眠不足、睡眠质量差,主要通过影响机体糖代谢与血压,导致胰岛素抵抗和代谢综合征,进而增加心血管疾病的发生风险。《欧洲心脏病学杂志》上的相关研究已证实,睡眠时长与冠心病之间的关系,大致呈U型曲线,即睡眠时间过短或过长,均与冠心病的较高发病风险相关。

土耳其学者发表在《Chronobiology international》杂志上的小样本量研究,有关注到不同睡眠类型人群,急性心肌梗死(AMI)的发病时间段存在明显差异。

早睡早起,一直被国人认为是健康的生活方式。这早睡类型的睡眠,会不会与更低的急性心梗发生风险相关呢?

日常早睡早起的戴博士有查阅到,南京医科大学第一附属医院心内科王连生教授等近日发表在《BMC Cardiovascular Disorders》上的最新研究,评估了睡眠习惯对中国人群AMI风险和冠状动脉疾病(CAD)严重程度的影响。

研究共纳入南京医科大学附属江宁医院心内科、南京医科大学第一附属医院心内科住院患者873例,其中AMI患者314例,余下559例设为对照组。其中,对照组包括 395例CAD患者,和164例非冠心病患者。

研究者通过面对面方式,使用SFQ睡眠调查问卷对患者睡眠习惯做了全面评估。使用Gensini评分,评估了AMI组和CAD组患者的冠状动脉疾病严重程度。

在对其他睡眠因素和人口统计学特征进行调整后,发现:

1. 晚睡(晚24点及之后)、晚醒(早7点后)或睡眠不足(不足6小时),均与较高的AMI发生风险相关。

2. 较低的夜间光照水平,与较低的AMI发生风险相关。

3. 在各年龄层中,无论年龄大小,晚睡、睡眠不足,均与AMI风险增加相关。

4. 在65岁及以下年龄的患者中,白天小睡与AMI风险降低相关。在65岁以上患者中,夜间醒来频次(3次)与AMI风险增加相关。

5. 睡眠不足与高Gensini评分风险增加相关。

总之,睡眠不足是急性心梗和冠脉疾病严重程度的重要危险因素。晚睡也与急性心梗风险增加相关。在中青年人中,经常小睡可能具有一定的保护作用。
