Excessive blood clotting is a recognized feature of severe COVID-19. But a new study suggests that some hospitalized patients may also be vulnerable to bleeding, which is associated with an increased risk of death.
Normally, our blood maintains a delicate balance between its tendency to form clots and its tendency to break them down.
In particular, the body does this by continually adjusting the activity of a protein in the blood called plasminogen, which promotes the breakup of blood clots, or “thrombolysis.”
