New evidence shows that patients with Long COVID syndrome continue to have higher measures of blood clotting, which may help explain their persistent symptoms, such as reduced physical fitness and fatigue. The study, led by researchers from RCSI University of Medicine and Health Sciences, is published in Opens in the Journal of Thrombosis and Haemostasis.
The researchers examined 50 patients with symptoms of Long COVID syndrome to better understand if abnormal blood clotting is involved.
They discovered that clotting markers were significantly elevated in the blood of patients with Long COVID syndrome compared with healthy controls. These clotting markers were higher in patients who required hospitalisation with their initial COVID-19 infection, but they also found that even those who were able to manage their illness at home still had persistently high clotting markers.
