8/26/2023 0 Comments Blood clot lungs cause![]() In this study, the platelets of people hospitalized with COVID-19 were found to be hyperactive, having increased activation and aggregation (clumping). An increase in inflammatory molecules that your immune system produces in response to viral infection could activate clotting.Īnother study that was published in the journal Blood supports some of the findings above.If endothelial cells aren’t being directly infected, damage to the tissues around them due to viral infection or your immune response could cause increased clotting.Because of this, the virus could directly invade and damage endothelial cells, triggering your body’s clotting mechanism. Endothelial cells express ACE2 protein, which the new coronavirus uses to enter cells.The exact cause of the increase in clotting markers is uncertain, but it could be due to one (or a combination) of the mechanisms below: The study found that the people in the ICU had higher levels of these clotting markers than those who weren’t in the ICU. Both endothelial cells and platelets are important for starting the clotting process. The markers in question are involved with the activation of the cells lining your blood vessels (endothelial cells) and platelets. Their blood was analyzed for various markers associated with clotting. Of these people, 48 were in the ICU and 20 were not. The study involved 68 people hospitalized with COVID-19. However, a recent study, published in the journal The Lancet Haematology, helps shed some light on this topic. It’s still unclear why blood clots develop in people with COVID-19. The study found that 42 percent of participants were under age 55 and had no existing risk factors for stroke. A small study looked at 14 people with COVID-19 who had experienced a stroke due to a blood clot. It’s still unknown how common blood clots are in individuals who have a mild case of COVID-19.ĬOVID-19 complications from blood clots can happen across all ages. This is potentially dangerous because the clot can restrict the flow of blood within your blood vessels, leading to complications like stroke or heart attack.īlood clots with COVID-19 have most often been seen in people who’ve been hospitalized with the disease.Ī study of 184 people in the ICU for severe COVID-19 found that 31 percent of these individuals experienced complications related to blood clots. However, sometimes blood clots form in the absence of an injury. These clump together to form a clot that plugs the injury and allows it to heal. When a blood vessel is injured, it produces proteins that attract platelets and other clotting factors. Normally, blood clots help stop bleeding when you’re injured. doi:10.3389/’s known about COVID-19 and the development of blood clots?
