Thrombosis and thromboembolism related to COVID‐19: A clarion call for obtaining solid estimates from large‐scale multicenter data

Abstract

Abstract The clinical spectrum of coronavirus disease 2019 (COVID‐19) is wide, ranging from minor, nonspecific symptoms to severe pneumonia, acute respiratory distress syndrome, multiorgan involvement, and shock. In severe cases, the acute systemic inflammatory response, coagulation activation, and diffuse endothelial damage may, in combination with hypoxia, immobilization, and underlying risk factors, result in potentially life‐threatening venous and arterial thrombotic events. The first data from single‐center retrospective studies suggest that thrombotic events are a key aspect of COVID‐19‐associated morbidity and mortality. We have planned and will be launching the COvid REgistry on THROMBOSIS (CORE‐THROMBOSIS), a large online registry of previously or currently hospitalized patients with COVID‐19. The study aims to (i) determine the rate of acute thrombotic events in consecutive hospitalized patients with coronavirus (COVID‐19); (ii) investigate the current use and trends in thromboprophylaxis regimens; and (iii) describe the use of imaging tests for the detection of cardiovascular events in patients with COVID‐19.
