C. Michael Gibson MD engagement report
@CMichaelGibson - 430K followers on X
Measured over 52 original posts from a 30-day window, last computed on August 30, 2026.
Engagement
A typical post picks up 21 interactions against 430K followers, an engagement rate of 0.005%. Measured over 52 original posts, its engagement rate beats 22% of 3,810 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 2.5K times each, and 0.857% of those impressions turn into an interaction. That is about 0.57% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, though only 17% of days saw any activity at all. Most posts go out around 09:00 UTC, and Saturday is the busiest day of the week. Of the 52 posts sampled, 98% carry an image or video and 75% link out. The account's strongest tracked post pulled 4.5K interactions, about 214x its own typical post. Recurring topics include #baiminstitute, #cardiology, #clinicalresearch.

Compared with accounts its own size
C. Michael Gibson MD's engagement rate beats 22% of the tracked X accounts closest to it in follower count (3,810 accounts, accounts of similar size (decile 7 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 46% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 09:00 UTC, and Saturday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

SINGLE-AF trial: In patients with atrial fibrillation and intermediate stroke risk, DOAC therapy lowered the risk of net adverse clinical events (stroke, systemic embolism, major bleeding, or CV death) compared to no anticoagulation at 24 months. View slides here: https://t.co/b36rhC1emf

EPIDAURUS trial: In patients with AF and ACS, dual antithrombotic therapy with DOAC and intensified P2Y12-inhibition with prasugrel or ticagrelor for 1 month was associated with a higher bleeding risk without reducing ischemic events compared to triple antithrombotic therapy.

Multiple independent analyses by researchers ensures the integrity of results. While journals require that the authors "have access to the data" authors often use data analyzed by others and not themselves. "Editors and reviewers need to decide whether authors should be permitted to outsource important analytic decisions." https://t.co/6h6S5BrS7y

I’m honored to deliver the keynote lecture, “The Future of Cardiology,” at the Bayer Innovators Evening during ESC Congress 2026 in Munich on Sunday, August 30. I look forward to discussing the innovations, technologies, and ideas that are shaping the future of cardiovascular care — and to exchanging perspectives with colleagues from around the world. #BaimInstitute #ClinicalResearch #Cardiology

- What is C. Michael Gibson MD's engagement rate on X?
- C. Michael Gibson MD (@CMichaelGibson) has an engagement rate of 0.005%, based on the median interactions across 52 original posts from the last 30 days against 429,519 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.005%, C. Michael Gibson MD sits above the 10th percentile of the 36,960 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @CMichaelGibson have real engagement?
- Its engagement rate beats 22% of the tracked X accounts closest to it in follower count (3,810 accounts), which puts it in the bottom quarter for its size group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @CMichaelGibson post?
- Most posts go out around 09:00 UTC, and Saturday is its busiest day, at roughly 1.9 posts per day across the measured window.
