【摘要】 目的 通过关键词共现分析和作者共现分析的方式，研究国内外循证心血管领域的研究热点、学科分支和发展趋势。 方法 通过检索中国生物医学数据库和Medline数据库，分别收集相关研究文献，并提取关键词词频、作者发文数和核心研究单位，对核心关键词和核心发文作者建立共现矩阵，使用Ucinet绘制可视化网络图。 结果 成功得到核心关键词和核心作者可视化网络。中文可视化网络包括循证医学、治疗和护理3个方面，英文可视化网络包括evidence-based medicine、therapy和treatment outcome 3个方面。而在作者合作可视化网络中，国内作者合作关系较为松散，合作团体较小，国外作者合作关系较为紧密，合作团体较大。国内核心研究机构分布于循证研究重点高校，国外则以发达国家为主。 结论 国内循证心血管研究领域总体发展趋势较好，但较国外相比仍存在一些不足，需要进一步加强重点研究，调整研究规划。【Abstract】 Objective To research on the hot issues, branch system and development trend of evidence-based cardiovascular medicine in and out of china by using co-word analysis of keywords and authors. Methods By Searching the CBM database in Chinese and Medline database in English, we collected the related articles and picked out the frequency of keywords, authors and core administrations, and built the matrix of keywords and authors. Finally we completed the visualized network by Ucinet. Results We successfully obtained the visualization of this subject. Chinese network contained three parts: evidence-based medicine, therapy and nursing, while English network also contained three parts: evidence-based medicine, therapy and treatment outcome. In the authors′ visualized network, Chinese authors had less cooperation and looser relationship compared with their counterparts overseas. The core administrations in china located in outstanding universities, and developed countries had the dominated roles in the world. Conclusions The development trend of evidence-based cardiovascular medicine in china is good, but still has some limitations compared with overseas studies. More emphasis should be put on strengthening core-area researching and research plan adjustment.
