2013—2023年缺血性卒中与睡眠相关性研究的文献计量学分析

Bibliometric Analysis of References on the Correlation between Ischemic Stroke and Sleep from 2013 to 2023

目的分析2013—2023年缺血性卒中和睡眠相关性研究的现状及研究热点。方法在Web of Science核心合集中检索2013年1月1日—2023年12月31日缺血性卒中和睡眠相关性研究的文献。使用RStudio的bibliometrix软件包和VOSviewer软件对该领域研究的发文量、国家/地区、机构、作者、期刊、文献引用、关键词和研究热点进行分析,并进行可视化呈现。结果共检索到798篇文献。以通信作者分析,中国发文199篇,居全球首位,且与多个国家建立了合作关系。美国发文196篇,位列第2。发文量最多的机构是加拿大多伦多大学,共34篇。发文量前10位的作者中5位来自美国密歇根大学,相互合作较密切,其中美国学者Devin L Brown发表文章数量为28篇,被引频次236次,发文量和被引频次均居首位。发文量最多的期刊是Sleep Medicine(74篇),发表文章被引频次最高的期刊是Stroke(3542次)。关键词可视化分析发现卒中与睡眠呼吸暂停出现频次最高。在卒中与睡眠相关性研究领域,研究主题分析提示失眠、抑郁作为基础课题对该领域发展非常重要,卒中预防、功能结局、脑血流主题研究需要努力开发。结论越来越多的研究聚焦于缺血性卒中和睡眠之间的关联性,中国和美国在该领域发表文献较多,睡眠呼吸障碍是主要研究热点。未来在卒中和睡眠领域可探索失眠、抑郁、卒中预防、功能结局、脑血流等主题。

Objective To analyze the current status and research hotspots of research on the correlation between ischemic stroke and sleep from 2013 to 2023.Methods A literature search was conducted in the Web of Science core collection for articles related to ischemic stroke and sleep published between January 1,2013,and December 31,2023.The bibliometrix package in RStudio and VOSviewer software were utilized to analyze and visualize the number of published studies,contributing countries/regions,institutions,authors,journals,citations,keywords,and research hotspots in this field.Results A total of 798 articles were retrieved.An analysis of corresponding authors revealed that China ranked first globally with 199 publications and established collaborations with multiple countries.The United States followed closely with 196 publications.The University of Toronto(Canada)was the leading institution with 34 publications.Among the top ten authors,five were from the University of Michigan(US),and they had close cooperation with each other.American scholar Devin L Brown published 28 articles and was cited 236 times,ranking first in the number of articles published and the frequency of citations.Sleep Medicine published the most articles on ischemic stroke and sleep(74 articles),while Stroke had the highest citation frequency(3542 times).Through the visual analysis of keywords,it was found that stroke and sleep apnea had the highest occurrence frequency.In the research field of the correlation between stroke and sleep,the analysis of research themes suggests that insomnia and depression are fundamental topics crucial to the development of this field.Stroke prevention,functional outcomes,and cerebral blood flow are potential themes that require further exploration.Conclusions An increasing number of studies have focused on the correlation between ischemic stroke and sleep.China and the United States have published more literature in this field,and sleep-disordered breathing is the major research hotspot.Future research in the field of stroke and sleep should explore themes such as insomnia,depression,stroke prevention,functional outcomes,and cerebral blood flow.
