Most heart attack videos on TikTok and Bilibili are only moderately accurate — they often lack citations, omit key facts, and don’t clearly state where their information comes from, making it hard for viewers to judge reliability.

Quality and reliability assessment of myocardial infarction short videos on Bilibili and TikTok: A cross-sectional study
Most heart attack videos on TikTok and Bilibili aren’t very accurate — they often leave out important info like how to prevent heart attacks and don’t say where their facts come from. Even the most popular videos aren’t the most reliable ones.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether the moderate quality observed in this study is consistent across global platforms and whether quality has improved or declined over time.
A systematic review and meta-analysis of all published cross-sectional studies (2015–2025) evaluating MI-related short video quality on global platforms using standardized tools (GQS, mDISCERN, JAMA), with subgroup analysis by region, platform, and time period.
Whether exposure to moderately high-quality MI videos (GQS 3–4) improves long-term knowledge retention compared to low-quality videos (GQS 1–2).
A prospective cohort study of 2,000 adults exposed to MI videos rated as GQS 1–2 vs. GQS 3–4, measuring knowledge retention at 1, 3, and 6 months, adjusting for baseline health literacy and platform usage.
Whether individuals who experienced a myocardial infarction were more likely to have been exposed to low-quality videos (GQS ≤2) than matched controls.
A case-control study comparing 300 MI patients to 300 controls, using digital footprint analysis to assess exposure to videos with GQS ≤2 vs. GQS ≥3 in the 12 months prior to event, adjusting for education and access.
Whether the median quality score of 3.0 on GQS is representative of MI-related content on these platforms at a given time.
A cross-sectional analysis of 500 MI-related videos on TikTok and Bilibili using GQS, mDISCERN, JAMA, and VIQI, conducted on multiple dates across 6 months to assess stability of median scores.
Anecdotal evidence that a single low-quality video (GQS=1) led to public misinformation.
A case series of 10 videos with GQS ≤1 and >50k views, documenting specific inaccuracies and public comments reflecting misunderstanding.
