Many factors are associated with hypertension, the most prevalent chronic disease, among which, the association of sleep disturbance and hypertension has received wide attention as sleep medicine advances rapidly in recent years. However, relevant studies on sleep disturbance and hypertension have some limitations, and there is no bibliometric analysis of hotspots about sleep disturbance and hypertension.

To review and summarize the research hotspots and trends of literature related to sleep disturbances and hypertension.

Studies about sleep disturbance and hypertension were searched in Web of Science Core Collection from inception to June 30, 2021 using "hypertension" and "sleep disturbance" "insomnia" "sleep deprivation" "sleep fragmentation" and "short-term sleep" as subject headings. CiteSpace 5.7.R5W was used for visual analysis.

In total, 4 589 studies were included for analysis. The number of studies generally showed an increasing trend, with a peak in 2018, and a rapider growth rate between 2011 and 2021. The top 10 most frequently used keywords in the studies published between 2011 and 2021 were hypertension, blood pressure, prevalence, obstructive sleep apnea, risk factor, sleep, cardiovascular disease, positive airway pressure, obesity and insomnia. The tag clusters were sleep time, sleep quality, sleep-disordered breathing, obstructive sleep apnea, sleep apnea, insomnia, stress, sleep, epidemiology, heart failure and symptoms. Keyword clustering analysis revealed that major directions in the studies published between 2011 and 2021 were: (1) the association of sleep-disordered breathing, especially obstructive sleep apnea, and hypertension; (2) the association of sleep time and blood pressure; (3) the association of sleep quality and blood pressure. The most frequently cited studies were mainly about sleep apnea, obstructive sleep apnea and short-term sleep. REDLINE was the most prolific author, and the largest group of authors was formed with her as the core. The US was the most prolific country, and the most prolific institution was the University of Pittsburgh.

The research on sleep disturbance and hypertension had become increasingly popular. The research hotspots of this field had changed greatly in 2011 and 2018. The effects of obstructive sleep apnea and sleep duration on hypertension were the mostly focused hotspots.

高血压作为最常见的慢性病，其影响因素众多。近年来睡眠医学高速发展，众多研究聚焦于探究睡眠障碍与高血压的关系。然而，睡眠障碍与高血压相关研究仍存在许多不足，且目前尚无探索睡眠障碍与高血压关系相关研究热点的文献计量学文章。

探索并总结睡眠障碍与高血压相关领域的研究热点和趋势。

文献检索来源Web of Science核心数据库，主题词为"高血压"和"睡眠障碍""失眠""睡眠剥夺""睡眠破碎""短时睡眠"，检索时间为建库至2021-06-30。使用CiteSpace 5.7.R5W对纳入文献进行可视化分析。

本文共纳入文献4 589篇，睡眠障碍和高血压关系的文献数量总体呈增长趋势，发文量最多的年份是2018年，2011年起发文量增长速度有所提高。近10年的相关文献出现频率最高的10个关键词分别为高血压、血压、患病率、阻塞性睡眠呼吸暂停（OSA）、危险因素、睡眠、心血管疾病、气道正压、肥胖、失眠。聚类标签分别为：睡眠时间、睡眠质量、睡眠呼吸紊乱、OSA、睡眠呼吸暂停、失眠、压力、睡眠、流行病学、心力衰竭、症状。对关键词聚类图谱结果进行进一步分析发现，近10年睡眠障碍与高血压相关主要研究方向分别是：（1）睡眠呼吸紊乱，尤其是OSA与高血压的关系；（2）睡眠时间与血压的关系；（3）睡眠质量与血压的关系。突现关键词被引频次最高的文献主要是对睡眠呼吸障碍、OSA和短时睡眠的研究。REDLINE是发文量最大的作者，围绕其形成了最大的作者集团。发文量最大的国家是美国，机构是匹兹堡大学。

睡眠障碍和高血压关系的关注度总体呈增长趋势。2011年与2018年该领域研究热点出现了较大变化。OSA和睡眠时间对高血压的影响是关注度最高的热点。
