A recent article in Science has uncovered important information about Long COVID-19. The study, which observed 39 healthy individuals and 113 COVID patients for up to a year, identified specific markers associated with Long COVID. It found that patients with Long COVID have ongoing activation of a part of their immune system called the complement system, which can lead to tissue damage and inflammation with potential blood clotting issues. The study also revealed lower levels of a protein called antithrombin III, increased platelet activation, and signs of immune system activation in Long COVID patients. These findings suggest the need for early heart assessments and potential treatments with antiviral medications and therapies targeting the complement system to help Long COVID patients.
