Dynamic Coagulation Function Changes in COVID-19 Survivors With Coronary Artery Disease

🚨CAD + COVID = hypercoagulable for 2 FULL YEARS. TEG sees it. Routine blood tests don’t. Standard blood thinners fail to fix it…….and possibly broader consequences, outside "CAD" !

➡️This retrospective single-center Chinees study examined 117 CAD patients admitted March–June 2022: 60 with confirmed acute COVID-19 and 57 carefully matched controls who never had COVID-19.

➡️All underwent conventional coagulation tests plus thromboelastography (TEG) at admission, 1 year, and 2 years post-discharge.

➡️Study findings:

Canadian COVID Forecast Jun 28-Jul 11, 2025 ONTARIO HIGH (no change) About 1 in every 118 people infected Compared to lowest point of pandemic in Canada: -Infections ~5X higher -Long COVID ~7X higher -Hospitalizations ~6X higher -Deaths ~5X higher
This image describes the Canadian COVID Forecast for the fourteen-day period between Jun 28-Jul 11, 2025, which is produced by COVID-19 Resources Canada. Ontario’s COVID Forecast outlook is HIGH (no change) with a COVID INDEX SCORE of 5.2
About 1 of every 118 people is infected.
Estimated infections this week: 90,950-119,000
What these numbers mean: MODERATE 1-5, HIGH 5-10, VERY HIGH 10-15, SEVERE >15 COMPARED TO THE LOWEST POINT IN THE COVID PANDEMIC IN CANADA
How much higher are key indicators compared to the lowest point in the COVID pandemic in Canada?
Waste water, infections: HIGH; 5.4X higher
Long COVID estimate:  HIGH; 6.5X higher
Hospitalizations, ICU: HIGH; 5.5X higher
Deaths: MODERATE; 4.9X higher
HOW TO HELP:
EVERYONE:
UPDATE vaccines every 6 months
WEAR N95-type masks

Who is HIGH RISK?
People 60 and older, babies < 1 year, pregnant
ALL AGES: immunocompromised OR medically at-risk OR no vaccine or infection in the last 6 months
Recommendations are based on the COVID-19 Risk Index from the Peterborough ON Public Health Unit

Study in Brazil & Portugal found COVID-19 accelerates “immune aging,” increasing exhausted T cells in all cases within 7 days. 

This effect is unique to COVID-19, not seen in other infections.

Good thread on a recent breakthrough paper. To me, key is the demonstration that by spike binding to fibrinogen to start the process, the pathology is confirmed to be SARS-Cov-2 specific. Pathology is not simply the result of generalized inflammation. It’s not ‘lots of viruses do this’ type thing. It’s Covid-specific pathology. As always, advanced knowledge like this is a v positive thing, offering solutions.
