To evaluate interest in coronary artery calcium (CAC) among the general public during the past 17 years and to compare trends with real-world data on number of CAC procedures performed.
We used Google Trends, a publicly available database, to access search query data in a systematic and quantitative fashion to search for CAC-related key terms. Search terms included , , , , and . We accessed Google Trends in January 2021 and analyzed data from 2004 to 2020.
From 2004 to December 31, 2020, CAC-related search interest (in relative search volume) increased continually worldwide (+201.9%) and in the United States (+354.8%). Three main events strongly influenced search interest in CAC: reports of a CAC scan of the president of the United States led to a transient 10-fold increase in early January 2018. American College of Cardiology/American Heart Association guideline release led to a sustained increase, and lockdown after the global pandemic due to COVID-19 led to a transient decrease. Real-world data on performed CAC scans showed an increase between 2006 and 2017 (+200.0%); during the same time period, relative search volume for CAC-related search terms increased in a similar pattern (+70.6%-1511.1%). For the search term , a potential representative of active online search for CAC scanning, we found a +28.8% increase in 2020 compared with 2017.
Google Trends, a valuable tool for assessing public interest in health-related topics, suggests increased overall interest in CAC during the last 17 years that mirrors real-world usage data. Increased interest is seemingly linked to reports of CAC testing in world leaders and endorsement in major guidelines.
评估过去17年公众对冠状动脉钙化（CAC）的关注程度，并将其趋势与实际进行的CAC检查数量的真实数据进行比较。
我们使用公开可用的数据库谷歌趋势，以系统和定量的方式获取搜索查询数据，以搜索与CAC相关的关键词。搜索词包括 、 、 、 和 。我们于2021年1月访问了谷歌趋势，并分析了2004年至2020年的数据。
从2004年到2020年12月31日，全球范围内与CAC相关的搜索兴趣（以相对搜索量衡量）持续上升（增长201.9%），在美国增长幅度更大（增长354.8%）。有三件主要事件对CAC的搜索兴趣产生了强烈影响：美国总统进行CAC扫描的报道导致2018年1月初搜索量短暂增长了10倍。美国心脏病学会/美国心脏协会指南的发布导致搜索量持续增加，以及因新冠疫情导致的全球大流行后的封锁措施使搜索量短暂下降。实际进行的CAC扫描的真实数据显示，2006年至2017年期间有所增加（增长200.0%）；在同一时期，与CAC相关搜索词的相对搜索量以类似模式增加（增长70.6%-1511.1%）。对于搜索词 （可作为对CAC扫描进行积极在线搜索的一个潜在代表），我们发现与2017年相比，2020年增长了28.8%。
谷歌趋势是评估公众对健康相关话题兴趣的一个有价值的工具，表明在过去17年中公众对CAC的总体兴趣有所增加，这与实际使用数据相符。兴趣的增加似乎与世界领导人进行CAC检测的报道以及主要指南中的认可有关。
