2018至2022年肥厚型心肌病研究概况的文献计量学分析

Bibliometrics Analysis of Studies on Hypertrophic Cardiomyopathy From 2018 to 2022

目的分析2018至2022年肥厚型心肌病的研究进展和热点话题。方法检索Web of Science核心合集数据库,纳入2018年1月1日至2022年12月31日发表的肥厚型心肌病相关文献,进行文献计量学分析。结果共纳入6355篇文献,平均被引频次7次,2021年出版文献最多,为1406篇。VOSviewer软件分析显示,肥厚型心肌病相关的猝死研究,特别是磁共振心肌延迟强化对猝死的预测价值是目前的热点话题,此外基因检测和新药mavacamten研究也成为一大热点。美国是目前肥厚型心肌病发文量和文献被引频次最多的国家,中国学者发文量位居第2位,但高质量的研究成果较少。结论猝死危险分层和预防仍是目前肥厚型心肌病领域重要和热点研究内容。国内学者应开展多中心合作,以提高研究成果的水平。

Objective To analyze the research progress and hot topics in hypertrophic cardiomyopathy from 2018 to 2022.Methods The publications in the field of hypertrophic cardiomyopathy from January 1,2018 to December 31,2022 were retrieved from Web of Science core collection database and included for a bibliometric analysis.Results A total of 6355 publications were included,with an average citation frequency of 7 times.The year 2021 witnessed the most publications(1406).The analysis with VOSviewer showed that the research on sudden death related to hypertrophic cardiomyopathy,especially the predictive value of late gadolinium-enhanced cardiac MRI in sudden death,was a hot topic.In addition,gene detection and the new drug mavacamten became hot research topics.The United States was the country with the largest number of publications and the highest citation frequency in this field.Chinese scholars produced the second largest number of publications,which,however,included few high-quality research results.Conclusions Risk stratification and prevention of sudden death is still an important and hot research content in the field of hypertrophic cardiomyopathy.Chinese scholars should carry out multi-center cooperation in the future to improve the research results.
