Bibliometric analysis, a powerful tool for assessing trends in research output, was employed to analyze the evolution of hypertension research over a 20-year period. The analysis was based on 90 308 original articles and a citation analysis. The use of bibliometric as a potential tool for shaping research policy at the institution or country level was also explored. The number of published hypertension articles increased by 43.5% over the 20-year period. By contrast, the increase in the number of articles in all medical disciplines was 96%, and in the cardiovascular field was 64%. Of the 6 countries producing the largest number of articles, the United States was consistently the major contributor. There was a slight decrease from Japan, a slight increase from the United Kingdom, and relatively stable output from Germany and Italy over the study period. Output from China showed the strongest growth. The trends in Specialization Index and Category Normalized Citation Impact varied by country. In Russia, Poland, and Brazil, increases in output were greater for hypertension research than for medical research in general. The United Kingdom and Denmark had greater hypertension research output than the other countries. VOSviewer analysis showed an intensification of collaborations between countries and a shift, over 10 years, from 3 clusters towards 2 clusters. Such analysis may help to shape research policy at the country level and can be similarly performed for institutions. Historical changes in hypertension research can be monitored over decades if the same channels continue to be used for communication of scientific results.
采用文献计量学分析方法，评估了 20 年来高血压研究的发展趋势。分析基于 90308 篇原始文章和引文分析。还探讨了将文献计量学作为机构或国家研究政策制定的潜在工具的使用。在 20 年期间，发表的高血压文章数量增加了 43.5%。相比之下，所有医学学科的文章数量增加了 96%，心血管领域的文章数量增加了 64%。在产生文章数量最多的 6 个国家中，美国一直是主要贡献者。日本略有下降，英国略有增加，德国和意大利在研究期间相对稳定。中国的产出增长最为强劲。专业化指数和类别标准化引文影响力的趋势因国家而异。在俄罗斯、波兰和巴西，高血压研究的产出增长大于一般医学研究。英国和丹麦的高血压研究产出高于其他国家。VOSviewer 分析显示，各国之间的合作加强，10 年来，从 3 个聚类转变为 2 个聚类。这种分析可能有助于制定国家层面的研究政策，并且可以对机构进行类似的分析。如果继续使用相同的渠道来交流科学成果，可以监测几十年高血压研究的历史变化。
