Lecture 15: Endotheliopathy of Long COVID
Etheresia Pretorius PhD
Presentation Date:
January 15, 2026
> In early 2020, we all became aware of a new pandemic, COVID-19.
> It quickly became apparent that in some patients the virus was associated with a severe coagulopathy, resulting in significant morbidity and mortality.
> Emerging evidence has indicated that coagulation changes play a major role in the pathophysiology of COVID, particularly Long-COVID, the persistent symptoms following infection.
> In this presentation, Dr. Resia Pretorius discusses use of cutting edge laboratory studies in coagulation and vascular biology, as it applies to COVID.
