Background 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. Objective To review and summarize the research hotspots and trends of literature related to sleep disturbances and hypertension. Methods 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. Results 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. Conclusion 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.
