Digital technology uses in cardiology have become a popular research focus in recent years. However, there has been no published bibliometric report that analyzed the corresponding academic literature in order to derive key publishing trends and characteristics of this scientific area.
We used a bibliometric approach to identify and analyze the academic literature on digital technology uses in cardiology, and to unveil popular research topics, key authors, institutions, countries, and journals. We further captured the cardiovascular conditions and diagnostic tools most commonly investigated within this field.
The Web of Science electronic database was queried to identify relevant papers on digital technology uses in cardiology. Publication and citation data were acquired directly from the database. Complete bibliographic data were exported to VOSviewer, a dedicated bibliometric software package, and related to the semantic content of titles, abstracts, and keywords. A term map was constructed for findings visualization.
The analysis was based on data from 12,529 papers. Of the top 5 most productive institutions, 4 were based in the United States. The United States was the most productive country (4224/12,529, 33.7%), followed by United Kingdom (1136/12,529, 9.1%), Germany (1067/12,529, 8.5%), China (682/12,529, 5.4%), and Italy (622/12,529, 5.0%). Cardiovascular diseases that had been frequently investigated included hypertension (152/12,529, 1.2%), atrial fibrillation (122/12,529, 1.0%), atherosclerosis (116/12,529, 0.9%), heart failure (106/12,529, 0.8%), and arterial stiffness (80/12,529, 0.6%). Recurring modalities were electrocardiography (170/12,529, 1.4%), angiography (127/12,529, 1.0%), echocardiography (127/12,529, 1.0%), digital subtraction angiography (111/12,529, 0.9%), and photoplethysmography (80/12,529, 0.6%). For a literature subset on smartphone apps and wearable devices, the Journal of Medical Internet Research (20/632, 3.2%) and other JMIR portfolio journals (51/632, 8.0%) were the major publishing venues.
Digital technology uses in cardiology target physicians, patients, and the general public. Their functions range from assisting diagnosis, recording cardiovascular parameters, and patient education, to teaching laypersons about cardiopulmonary resuscitation. This field already has had a great impact in health care, and we anticipate continued growth.
近年来，数字技术在心脏病学中的应用已成为一个热门的研究焦点。然而，目前还没有发表过对相关学术文献进行分析的文献计量报告，以揭示该科学领域的关键出版趋势和特征。
我们使用文献计量学方法来确定和分析心脏病学中数字技术应用的学术文献，并揭示热门研究主题、主要作者、机构、国家和期刊。我们进一步捕捉了该领域中最常见的心血管状况和诊断工具。
通过 Web of Science 电子数据库查询有关心脏病学中数字技术应用的相关论文。直接从数据库中获取出版和引用数据。完整的书目数据被导出到专门的文献计量软件包 VOSviewer 中，并与标题、摘要和关键词的语义内容相关联。为了发现可视化，构建了一个术语地图。
该分析基于来自 12529 篇论文的数据。在排名前 5 的最具生产力的机构中，有 4 家来自美国。美国是最具生产力的国家（4224/12529，33.7%），其次是英国（1136/12529，9.1%）、德国（1067/12529，8.5%）、中国（682/12529，5.4%）和意大利（622/12529，5.0%）。经常研究的心血管疾病包括高血压（152/12529，1.2%）、心房颤动（122/12529，1.0%）、动脉粥样硬化（116/12529，0.9%）、心力衰竭（106/12529，0.8%）和动脉僵硬度（80/12529，0.6%）。反复出现的模式是心电图（170/12529，1.4%）、血管造影（127/12529，1.0%）、超声心动图（127/12529，1.0%）、数字减影血管造影（111/12529，0.9%）和光电容积描记法（80/12529，0.6%）。对于智能手机应用程序和可穿戴设备文献的一个子集，《医学互联网研究杂志》（20/632，3.2%）和其他 JMIR 组合期刊（51/632，8.0%）是主要的出版渠道。
心脏病学中的数字技术应用针对医生、患者和普通大众。它们的功能范围从协助诊断、记录心血管参数和患者教育，到向非专业人士传授心肺复苏术。该领域已经对医疗保健产生了重大影响，我们预计它将继续增长。
