The number of citations an article receives is an important indication of its impact and contribution to the clinical world. There is a paucity of literature concerning top article citations in cardiology. The main objective of this investigation was to bridge this gap and to provide readers a practical guide in evaluating the cardiovascular literature. Scopus Library database was searched to determine the citations of all published cardiovascular articles. One hundred two journals were included in our investigation under the Institute of Science Information Web of Science subject category "cardiology, cardiovascular, and heart." We did not apply any time or study-type restriction in our search. The top 100 cited articles were selected and analyzed by 2 independent investigators. The journal with the highest number of top 100 cited articles was Circulation with 36, followed by 28 in the European Heart Journal. A statistically significant association was found between the journal impact factor and the number of top 100 cited articles (p <0.005). United States had the highest number of articles (49). Contrary to bibliometric analyses published in other medical fields, the largest subset of the cardiology articles (n = 42) was published in the 5-year period from 2006 to 2010. General medical journals such as The Lancet (n = 4) and The New England Journal of Medicine (n = 1) contributed only 5 articles to the list despite their extremely high impact factors. In conclusion, our analysis provides an insight on the citation frequency of top cited articles published in cardiovascular medicine to help recognize the quality of the works, discoveries, and the trends steering cardiology.
一篇文章获得的引用次数是其影响力以及对临床领域贡献的重要指标。关于心脏病学领域高引用文章的文献较少。本研究的主要目的是填补这一空白，并为读者提供一份评估心血管文献的实用指南。我们检索了Scopus图书馆数据库，以确定所有已发表的心血管文章的引用情况。在科学信息研究所的科学网学科分类“心脏病学、心血管病学和心脏”下，共有102种期刊被纳入我们的研究。我们在检索中未施加任何时间或研究类型限制。由两名独立研究人员挑选并分析了被引用次数排名前100的文章。被引用次数排名前100的文章数量最多的期刊是《循环》，有36篇，其次是《欧洲心脏杂志》，有28篇。我们发现期刊影响因子与被引用次数排名前100的文章数量之间存在统计学上的显著关联（p<0.005）。美国发表的文章数量最多（49篇）。与其他医学领域发表的文献计量分析结果相反，心脏病学文章中最大的子集（n = 42）是在2006年至2010年这5年期间发表的。尽管《柳叶刀》（n = 4）和《新英格兰医学杂志》（n = 1）等综合医学期刊影响因子极高，但它们在这份榜单中仅贡献了5篇文章。总之，我们的分析提供了对心血管医学领域高引用文章引用频率的见解，以帮助认识这些研究成果、发现以及引领心脏病学发展的趋势的质量。
