Evidence is building that Covid-19 can cause blood clotting abnormalities in patients, which could increase their risk of death.
Researchers in Ireland have reported finding that patients with severe coronavirus infection have micro blood clots in their lungs – something they say is not seen in other lung conditions, and could explain why people with severe Covid-19 have a drastic drop in blood oxygen levels.
The study, published in the British Journal of Haematology by researchers at the Irish Centre for Vascular Biology, RCSI and St James’s hospital, Dublin, also reveals the higher the levels of various markers indicating abnormal blood clotting, the worse a patient’s prognosis.
“Further studies will be required to investigate whether different blood thinning treatments may have a role in selected high-risk patients in order to reduce the risk of clot formation,” said Prof James O’Donnell director of the Irish Centre for Vascular Biology.
