Heart attack videos on TikTok are shorter and get more likes and shares than those on Bilibili, but both platforms have similar levels of medical accuracy — meaning how the platform works affects how people watch, not how accurate the information is.

Quality and reliability assessment of myocardial infarction short videos on Bilibili and TikTok: A cross-sectional study
TikTok and Bilibili heart attack videos are equally accurate, but TikTok videos get more likes and are shorter — and the study shows that popular videos aren’t more accurate, meaning how the app works matters more than how right the info is.

- No clinical evidence is available; the score reflects mechanistic plausibility only.
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 altering video length or platform interface (TikTok-style vs. Bilibili-style) directly affects viewer retention or knowledge acquisition of MI information.
A randomized controlled trial assigning 400 participants to view identical MI content in either TikTok-style (60s, fast cuts, music) or Bilibili-style (3–5 min, bullet-screen comments, detailed narration), measuring immediate knowledge retention, emotional response, and willingness to share.
Whether users of TikTok vs. Bilibili develop different levels of MI knowledge or preventive behaviors over time due to platform-specific content formats.
A prospective cohort study following 3,000 regular users of TikTok and Bilibili, tracking their exposure to MI content, platform usage patterns, and changes in MI knowledge and preventive behaviors over 12 months.
Whether individuals who delayed MI care were more likely to have consumed content primarily on TikTok vs. Bilibili.
A case-control study comparing 200 MI patients with delayed care to 200 with timely care, analyzing their primary platform (TikTok vs. Bilibili) and content format exposure in the 6 months prior to event.
Whether TikTok and Bilibili differ in video length and engagement while maintaining similar quality scores for MI content.
A cross-sectional analysis of 500 MI-related videos from each platform, measuring duration, engagement metrics, and quality scores (GQS, mDISCERN), replicated across multiple dates.
Anecdotal evidence that a single TikTok video’s short format led to better engagement than a longer Bilibili video with identical content.
A case series comparing 10 pairs of identical MI educational videos uploaded to both platforms, differing only in length and editing style, measuring engagement and viewer comments.
