Stroke-associated pneumonia (SAP) is a spectrum of pulmonary infections in patients within 7 days of stroke. Which is one of the most common complications after stroke and is significantly associated with a poor prognosis of stroke. To the best of our knowledge, a bibliometric method was not previously used to analyze the topic of SAP; we aim to describe the situation and evolution of SAP from 2003 to 2020, and to discuss the research hotspots and frontiers.A total of 151 articles were retrieved from the Scopus database. Bibliometric analysis was used to explore the dynamic trends of articles and the top subject areas, journals, institutes, citations, and co-keywords. VOS viewer software (version 1.6.15) was used to graphically map the hot topics of SAP based on the co-keywords.A total of 151 articles were identified. Articles have increased over the recent years and faster in the last 2 years (55 articles, 36.4%), the majority of subject areas are medicine (124 articles, 82.1%) and neuroscience (38 articles, 25.2%). The "Journal Of Stroke And Cerebrovascular Diseases" with 15 articles has been scored as the first rank followed by "Plos One." Regarding the geographical distribution of articles, China is the most productive country with 50 articles (33.1%), others are more prominent in Europe, and most institutes are universities. Citations have increased over time, the main country of the top five highly cited published articles are Germany and before 2008. The co-keywords are mainly divided into four aspects: risk factors, predictive scores, preventions, and outcomes.This study could provide practical sources for researchers to find the top subject areas, journals, institutes, citations, and co-keywords. Moreover, the study could pave the way for researchers to be engaged in studies potentially lead to more articles in this field.
卒中相关性肺炎（SAP）是指卒中后 7 天内患者发生的肺部感染，是卒中后最常见的并发症之一，与卒中预后不良显著相关。据我们所知，之前尚未使用文献计量学方法来分析 SAP 这一主题，我们旨在描述 2003 年至 2020 年 SAP 的现状和演变，并讨论研究热点和前沿。
从 Scopus 数据库中检索到 151 篇文章。使用文献计量学分析来探讨文章和顶级主题领域、期刊、机构、引用和共关键词的动态趋势。VOS viewer 软件（版本 1.6.15）用于根据共关键词绘制 SAP 的热门话题图。
共确定了 151 篇文章。近年来，文章数量有所增加，尤其是在过去 2 年中增长更快（55 篇，36.4%），大部分主题领域为医学（124 篇，82.1%）和神经科学（38 篇，25.2%）。引用量随着时间的推移而增加，排名第一的期刊是《中风与脑血管病杂志》（15 篇），其次是《PLoS One》。就文章的地理分布而言，中国是最具生产力的国家，有 50 篇文章（33.1%），其他国家则在欧洲更为突出，而大多数机构都是大学。
综上所述，该研究为研究人员提供了实用的资源，可用于查找顶级主题领域、期刊、机构、引用和共关键词。此外，该研究为研究人员提供了潜在的研究方向，可能会使该领域的文章数量增加。
