SINGAPORE - People who have recovered from Covid-19, regardless of the severity of their disease, may be at risk of developing blood clots due to an overactive immune system, according to a study by local scientists. Blood clots in major arteries, especially those which are linked to vital organs, can increase a person's risk of heart attack, stroke or organ failure. Blood samples from 30 patients who had recovered from mild, moderate and severe Covid-19 were collected a month after they had been discharged from the hospital. All of them were found to have blood vessel damage, possibly arising from a lingering immune response, which could trigger the formation of blood clots. Around half of the patients had pre-existing cardiovascular risks, such as diabetes and hypertension, which put them at higher risk of blood clotting, said Assistant Professor Christine Cheung from Nanyang Technological University's Lee Kong Chian School of Medicine on Tuesday (April 13). Speaking at a virtual media briefing, she noted that these patients also had more pronounced blood vessel dysfunction compared with the group who had no cardiovascular risks. Read more
