Abstract:

BACKGROUND: As the exact mechanism of vascular restenosis after cardiovascular stent implantation is unclear, to reduce the incidence of restenosis after implantation becomes increasingly urgent. The occurrence of vascular restenosis after stent implantation is associated with the corrosion resistance of stents, Young’s modulus, yield strength and material flexibility, as well as the host’s inflammatory response, endothelial cell proliferation, and fibrous tissue proliferation after stent implantation.

OBJECTIVE: To analyze the international research trend of cardiovascular stent biocompatibility based on data from Web of Science and Clincaltrials.gov, in order to provide a reference basis for relevant studies.
METHODS: (1) Keywords of “cardiovascular stent” and “biocompatibility” were used for article retrieval. (2) The retrieval time was from 2005 to 2014. (3) Information sources: Web of Science and Clincaltrials.gov.
RESULTS AND CONCLUSION: (1) Totally 2 875 articles included in Web of Science (2005-2014) were enrolled and analyzed using analytic tools of the Web of Science. Then, eight articles with high citation frequency were obtained. (2) There are 2 875 articles addressing the biocompatibility of cardiovascular stent materials included in the Web of Science (2005-2014), among which, 931 articles come from the U.S.A and account for 32.383%. During 2005-2014, the institutions publishing literatures about biocompatibility of cardiovascular stent materials are ranked as follows: Harvard University, Brigham and Women’s Hospital, Medical University of Vienna, Erasmus University Rotterdam, Columbia University. American Journal of Cardiology has published 117 relevant articles, which ranks the first in this field, and the number of published literature accounts for 4.070% of all literature. In recent years, international literature about cardiovascular stent biocompatibility shows an overall gradual upward trend. Of the 2 875 articles published from 2005 to 2014, 223 articles come from China, ranking the fourth. It indicates that there are more achievements in this field in China. (3) There are 155 clinical trials about the biocompatibility of cardiovascular stent materials included in Clincaltrials.gov from 2005 to 2014, including 140 interventional studies and 15 observational studies.
