COVID-19 and Thrombosis: Clinical Aspects

Curr Drug Targets. 2022 Oct 5. doi: 10.2174/1389450123666221005092350. Online ahead of print.ABSTRACTIn coronavirus disease 2019 [COVID-19], thrombus formation is related to the pathogenesis of acute respiratory distress syndrome [ARDS] and the progression of clinical symptoms. Severe damage to vascular endothelial cells and the associated cytokine storm after SARS-CoV-2 infection cause thrombogenesis and contribute to the development of more severe and unique thromboses compared to other infectious diseases. Thromboses occur more often in critically ill patients. In addition to pulmonary thromboembolism [PE] and deep vein thrombosis, acute myocardial infarction, peripheral arterial thrombosis, and aortic thrombosis have also been reported. In PE, thrombi develop in both pulmonary arteries and alveolar capillaries. These, together with intra-alveolar fibrin deposition, interfere with effective gaseous exchange in the lungs and exacerbate the clinical symptoms of ARDS in patients with COVID-19. Pharmacological thromboprophylaxis is recommended for all hospitalized patients to prevent both thrombosis and aggravation of ARDS, and other organ failures. Although the pediatric population is mostly asymptomatic or develops mild disease after SARS-CoV-2 infection, a new inflammatory disorder affecting the cardiovascular system, multisystem inflammatory syndrome in children [MIS-C], has been reported. Similar to Kawasaki disease, acute myocarditis, coronary vasculitis, and aneurysms a...
