Bibliometric Analysis of the Results of Cardio-Oncology Research.

OBJECTIVE

To analyze the development of cardio-oncology, summarize the research achievements, and provide proposals for its future research.

METHODS

The web of science database was used to search for "cardio-oncology" and "oncocardiology" related articles from the beginning of the database (1970) to April 5, 2019. Excel 2016 and Cytoscape were used to analyze the trend of cardio-oncology research.

RESULTS

A total of 356 articles were obtained. The number of articles has grown rapidly in recent years. Cardiac injury caused by tumor therapy was a research hotspot ( = 107). Researchers paid more attention to the prevention and treatment of cardiotoxicity ( = 54). Experimental researches were a small part of all studies ( = 72), mainly focusing on the study of cancer drugs' cardiac injury, test indicators of cardiotoxicity, and preventive drugs. The United States ( = 156.25), Italy ( = 48.5), and Canada ( = 23.5) published the most articles, making a great contribution to the development of cardio-oncology.

CONCLUSIONS

Cardio-oncology has been developing rapidly and receiving a large amount of research efforts in recent years. Most articles on cardio-oncology were published by the authors from the United States (44%) and Italy (17%), while other countries need to pay more attention to cardio-oncology. As an independent discipline, cardio-oncology is certainly in need of significant progress, but it has formed a basic framework, which has obtained many leading theories and meaningful achievements in diagnostic criteria, diagnostic methods, prevention and treatment, mechanism research, and influencing factor. Cardiac injury of tumor drugs has always been a research hotspot in this discipline, and there is still a lot of research space. The research about detection methods of cardiotoxicity and preventive drugs is gradually increasing. Basic research lags behind, and many mechanisms are still unclear.
