In this regard, Dr. Hou Yingzhong believes that thrombosis is a very common and dangerous complication for patients with COVID-19 (severe special infectious pneumonia, new coronary pneumonia, Wuhan pneumonia). Regarding the reason why COVID-19 increases the probability of thrombosis, Dr. Hou Yingzhong explained that viral infection can cause a systemic inflammatory response, which in turn affects the anticoagulant function of human endothelial cells, and promotes platelet activation to produce coagulation, which in turn causes thrombosis.
Dr. Hou Yingzhong added job email list that because of the rapid blood flow in the arteries, platelets are not easily deposited and attached, so thrombosis occurs more often in the veins. The venous blood flow is relatively slow, and platelets are easily attached to the blood vessel wall, resulting in small thrombus. The small thrombus flows over and gradually forms active thrombus, and then slowly accumulates into a large thrombus, which is easily stuck in the lungs, kidneys, heart and even the human body. brain. 1 Image source: Courtesy of Dr. Hou Yingzhong Dr. Hou Yingzhong said that if COVID-19 causes the body to become inflamed twice, the symptoms will never be milder than the first time. Repeated inflammation of blood vessels may increase the risk of sclerosis.
Therefore, patients with three highs must pay more attention. Once infected, patients with three high levels may increase the risk of cardiovascular embolism For groups prone to thrombosis, Dr. Hou Yingzhong admitted that blood sugar, blood fat, and blood pressure can damage the endothelial cells of blood vessels. Therefore, patients with diabetes, hypertension, and hyperlipidemia have a higher risk of thrombosis. In addition, this group itself is a In high-risk groups of stroke and myocardial infarction, if the infection is coupled with the infection, the body will become inflamed, the receptors of endothelial cells will be injured, and the blood will be more likely to coagulate on the blood vessels, thus causing embolism. Recently, many confirmed cases have been reported to have "long new crown symptoms" after recovery. The symptoms may be related to damage to blood vessels, lungs, and brain for about six months; however, a study in the of contracting cardiovascular disease and diabetes.
