The field of myocardial injury repair is developing rapidly and attracts attention from all over the world. The papers and patents represent the scientific and technological innovations in the field of myocardial injury repair, and this paper analyzed the global competition situation and research development trends in the field of myocardial injury repair, providing a reference for the research and judgment of the development situation in related fields in China. The number of published papers and patent applications in the field of myocardial injury repair around the world is generally increasing. The United States is a leader in this field, and China's R&D capabilities need to be further improved. The United States and China rank first and second in the world in terms of the number of related research results. The influence of American papers and patents is very prominent, and the number of core papers and core patents ranks first in the world. The comprehensive influence of Chinese papers and patents is less than that of developed countries/regions such as Europe and the United States, but the number of core papers and core patents is second only to the United States. The influence of papers or patents in developed countries such as Germany, Japan and Italy are more prominent. The main R&D institutions in this field are mainly companies and universities in developed countries, and Chinese companies are less involved. The University of Washington, Massachusetts Institute of Technology, Duke University and Harvard University in the United States have published a large number of papers and their influence is high. Institutions such as Melitron and Abbott Cardiovascular Systems in the United States have applied for a large number of patents and the patent value is higher. Research hotspots in the field of myocardial injury repair include cell repair, biomaterial development, and mechanism research on myocardial injury repair. The research contents of core papers and core patents also mainly focus on the mechanism of inducing differentiation of stem cells, and the development of new materials such as hydrogels and nanometers. In the future, interdisciplinary development will be the main focus.
