Quality and reliability assessment of myocardial infarction short videos on Bilibili and TikTok: A cross-sectional study
Heart doctors' videos on TikTok and Bilibili were found to be more accurate and complete than videos made by regular people or non-doctors, because they scored higher on official quality checks.

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 training non-professional creators to follow cardiologist-approved content guidelines directly improves video quality scores compared to untrained creators.
A randomized controlled trial assigning 200 content creators to either receive standardized training from cardiologists on MI content (including epidemiology, prevention, and source citation) or no training, then producing and submitting videos on MI, with quality scores (GQS, mDISCERN, JAMA, VIQI) as primary outcomes measured by blinded reviewers.
Whether viewers who consistently watch cardiologist-uploaded MI videos demonstrate better long-term knowledge retention and preventive health behaviors than those who watch non-professional content.
A prospective cohort study following 1,000 adults who regularly consume MI-related short videos, classifying them by primary uploader type (cardiologist vs. non-cardiologist), and measuring changes in MI knowledge, risk factor awareness, and preventive behaviors (e.g., aspirin use, symptom recognition) over 18 months.
Whether individuals who experienced a myocardial infarction were less likely to have previously watched cardiologist-uploaded videos compared to matched controls.
A case-control study comparing 250 MI patients to 250 matched controls, using digital history analysis to determine exposure frequency to cardiologist-uploaded MI videos in the 6 months prior to event, adjusting for education, access, and platform usage patterns.
Whether the proportion of cardiologist-uploaded videos in a region correlates with population-level knowledge of MI prevention and symptom recognition.
A cross-sectional survey of 5,000 adults across 10 Chinese cities, measuring MI knowledge and prevention awareness, matched with content analysis of the top 100 MI videos on TikTok and Bilibili in each city, testing for correlation between cardiologist video prevalence and public knowledge scores.
Anecdotal evidence that a single cardiologist’s video led to improved public recognition of MI symptoms in a community.
A case series of 10 communities where a cardiologist posted a viral MI video, documenting changes in local emergency department visits for chest pain, public social media discussions, and pre-hospital delays before and after the video’s release.
