Research focus and theme trend on fulminant myocarditis: A bibliometric analysis

Abstract

AimsThis study intends to explore the research focus and trends of fulminant myocarditis (FM) to have a better understanding of the topic.Materials and methodsThe data were downloaded from the Web of Science (WoS) database using the topic (TS) advanced search strategy. Many instruments were used to extract, analyze, and visualize the data, such as Microsoft Excel, HistCite Pro, GunnMap, BibExcel, and VOSviewer.ResultsFrom 1985 to 2022, 726 documents were indexed in the WoS. The United States and Columbia University were the most productive country and institutions. Keywords co-occurrence was carried out and four research themes were identified. In addition, the top three prolific authors, the first three highly cited authors, and the core authors of the author co-citation network were identified. The topics that they kept an eye on were analyzed, and the research areas of key authors were similar to the results of keyword co-occurrence. The hot topics of FM were related to the mechanical circulatory support, etiology, diagnosis, and the disease or therapy associated with FM.ConclusionThis study carried out a systematic analysis of the documents related to FM from 1985 to 2022, which can provide a guideline for researchers to understand the theme trend to promote future research to be carried out.

Analyzing fulminant myocarditis research trends and characteristics using the follower-leading clustering algorithm (FLCA): A bibliometric study

“…The Huazhong University of Science and Technology (China) takes the top spot in terms of both publications and CJALscores. This differs from the previous study, [12] where Columbia University ranked first (although Huazhong University of Science and Technology (China) was placed second). The discrepancy in the rankings could be attributed to the inclusion criteria for authors in the computation.…”

“…Enrico Ammirati from Italy emerged as the most productive author in terms of first and corresponding authorship, which differed from the previous study [12] where Klingel held the top position (with 12 articles, whereas Klingel was in the second position with 11 articles). However, in a more comprehensive analysis considering all coauthors and their respective WCDs, [27] Klingel ranked 7th (with a WCD of 4.43), which was lower than the top-ranked author Ammirati (with a WCD of 7.31).…”

“…These findings align with the results of a previous study. [12] However, in regard to research institutes, there is a difference. The Huazhong University of Science and Technology (China) takes the top spot in terms of both publications and CJALscores.…”

“…The discrepancy in the rankings could be attributed to the inclusion criteria for authors in the computation. In this study, only the first and corresponding authors were considered, whereas the previous study [12] did not specify whether they included only the first author or all authors. This difference in methodology regarding author inclusion may have contributed to the variation in rankings between the 2 studies.…”

“…[18] It has proven successful in various fields of research. [19–21] While some research [12] has been conducted on the focus and thematic trends of fulminant myocarditis using CiteSpace [22] and VOSviewer, [23] there are certain limitations that need to be addressed in future studies. These limitations include the absence of cluster analysis to classify article themes and features, a lack of clarity in the author cocitation network related to FM, such as the utilization of timeline view, [24] time zone view, [25] and dual-map overlay of journals [26] using CiteSpace software, [17] and the absence of dashboard-type visualizations to provide readers with a comprehensive understanding of FM’s development over the past several decades.…”
