基于Citespace探讨心肌梗死患者预后研究热点和趋势

Research hotspot and trend of prognosis of patients with myocardial infarction based on Citespace

目的通过Citespace软件分析2012年至2022年心肌梗死患者预后领域的文献,总结心肌梗死患者预后领域的研究热点,对未来研究方向进行预测。方法在Web of Science核心数据库中进行文献检索;使用Citespace软件统计并绘制年发文量、作者机构及关键词、共被引可视化图谱,同时对关键词、共被引进行聚类绘图、分析。结果共纳入835篇文献,平均年发文量稳定在80篇以上;该领域中核心研究学者为Nicolas Danchin和Myung Ho Jeong;最高产机构为杜克大学及杜克大学医学中心。关键词共现图谱中,出现频次排名前10的关键词包括临床结局、危险因素、冠状动脉介入手术等。共被引聚类分析提示,目前指南依然是心肌梗死研究的重要节点文章。结论2012年至2022年,心肌梗死预后研究热点包括:恶性心血管事件的发生风险及相关影响因素的研究,心肌梗死急救方案的优化,如何使心梗预后合并症减轻、恶性心血管事件减少。未来研究将聚焦于心肌梗死后心源性猝死的预防及治疗,并进一步探索不同人群冠状动脉介入手术的获益风险比。

Objective To analyze the literature in the field of prognosis of patients with myocardial infarction from 2012 to 2022 by CiteSpace software,summarize the research hotspots in the field of prognosis of patients with myocardial infarction,and predict the future research direction.Methods Literature search was carried out in the core database of web of science;CiteSpace software was used to count and draw the annual number of documents,author organization,keywords and co-citation visual map,and cluster drawing and analysis of keywords and co-citation were carried out at the same time.Results A total of 835 articles were included,and the average annual number of articles was more than 80.The core research scholars in this field are Nicolas Danchin and Myung ho Jeong,the most productive institutions are Duke University and Duke University Medical Center.In the keyword co-occurrence map,the top 10 keywords in frequency were clinical outcome,risk factors,percutaneous coronary intervention,etc.The co-cited cluster analysis suggested that the current guide is still an important node article in the study of myocardial infarction.Conclusion It is found that the research hotspots in 2012-2022 include the risk of malignant cardiovascular events after myocardial infarction and related influencing factors.Optimization of first aid plan for myocardial infarction;how to reduce the prognosis complications of myocardial infarction and reduce the malignant cardiovascular events.Future studies may focus on the prevention and treatment of sudden cardiac death after myocardial infarction,and will continue to explore the benefit risk ratio of coronary intervention in different populations.
