The incidence of Takotsubo syndrome (TTS), also known as the broken heart syndrome or stress cardiomyopathy, is increasing worldwide. The understanding of its prognosis has been progressively evolving and currently appears to be poorer than previously thought, which has attracted the attention of researchers. An attempt to recognize the awareness of this condition among the general population drove us to analyze the dissemination of this topic on TikTok, a popular short-video-based social media platform. We found a considerable number of videos on TTS on TikTok; however, the quality of the presented information remains unknown.
The aim of this study was to analyze the quality and audience engagement of TTS-related videos on TikTok.
Videos on the TikTok platform were explored on August 2, 2021 to identify those related to TTS by using 6 Chinese keywords. A total of 2549 videos were found, of which 80 met our inclusion criteria and were evaluated for their characteristics, content, quality, and reliability. The quality and reliability were rated using the DISCERN instrument and the Journal of the American Medical Association (JAMA) criteria by 2 reviewers independently, and a score was assigned. Descriptive statistics were generated, and the Kruskal-Wallis test was used for statistical analysis. Multiple linear regression was performed to evaluate the association between audience engagement and other factors such as video content, video quality, and author types.
The scores assigned to the selected video content were low with regard to the diagnosis (0.66/2) and management (0.34/2) of TTS. The evaluated videos were found to have an average score of 36.93 out of 80 on the DISCERN instrument and 1.51 out of 4 per the JAMA criteria. None of the evaluated videos met all the JAMA criteria. The quality of the relayed information varied by source (All P<.05). TTS-related videos made by health care professionals accounted for 28% (22/80) of all the evaluated videos and had the highest DISCERN scores with an average of 40.59 out of 80. Multiple linear regression analysis showed that author types that identified as health professionals (exponentiated regression coefficient 17.48, 95% CI 2.29-133.52; P=.006) and individual science communicators (exponentiated regression coefficient 13.38, 95% CI 1.83-97.88; P=.01) were significant and independent determinants of audience engagement (in terms of the number of likes). Other author types of videos, video content, and DISCERN document scores were not associated with higher likes.
We found that the quality of videos regarding TTS for patient education on TikTok is poor. Patients should be cautious about health-related information on TikTok. The formulation of a measure for video quality review is necessary, especially when the purpose of the published content is to educate and increase awareness on a health-related topic.
Takotsubo 综合征（TTS），又称心碎综合征或应激性心肌病，其发病率在全球范围内呈上升趋势。目前对其预后的认识正在不断发展，且似乎比之前认为的更差，这引起了研究人员的关注。我们试图了解公众对这种疾病的认识，因此分析了 TikTok 上关于 TTS 的话题传播情况，这是一个流行的短视频社交媒体平台。我们在 TikTok 上发现了相当数量的 TTS 视频，但呈现的信息质量仍不得而知。
本研究旨在分析 TikTok 上与 TTS 相关的视频的质量和观众参与度。
于 2021 年 8 月 2 日在 TikTok 平台上搜索与 TTS 相关的视频，使用 6 个中文关键词识别 TTS 相关视频。共发现 2549 个视频，其中 80 个符合纳入标准，并对其特征、内容、质量和可靠性进行评估。两名评审员独立使用 DISCERN 量表和《美国医学会杂志》（JAMA）标准对视频质量和可靠性进行评分，并分配分数。生成描述性统计数据，并使用 Kruskal-Wallis 检验进行统计分析。进行多元线性回归，以评估观众参与度与视频内容、视频质量和作者类型等其他因素之间的关系。
所选视频内容在 TTS 的诊断（0.66/2）和管理（0.34/2）方面的评分较低。评估的视频在 DISCERN 量表中的平均得分为 36.93 分（满分 80 分），在 JAMA 标准中平均得分为 1.51 分（满分 4 分）。评估的视频中没有一个符合所有 JAMA 标准。信息来源不同，传递的信息质量也不同（均 P<.05）。由医疗保健专业人员制作的 TTS 相关视频占所有评估视频的 28%（22/80），DISCERN 评分最高，平均得分为 40.59 分（满分 80 分）。多元线性回归分析显示，作为健康专业人员的作者类型（指数回归系数 17.48，95%CI 2.29-133.52；P=.006）和个体科学传播者（指数回归系数 13.38，95%CI 1.83-97.88；P=.01）是观众参与度（以点赞数表示）的显著且独立的决定因素。其他类型的作者、视频内容和 DISCERN 文档评分与较高的点赞数无关。
我们发现，TikTok 上用于患者教育的 TTS 相关视频质量较差。患者应谨慎对待 TikTok 上的健康相关信息。有必要制定视频质量审查措施，特别是当发布内容的目的是教育和提高公众对健康相关主题的认识时。
