Published:January 12, 2022DOI:https://doi.org/10.1016/j.ebiom.2022.103812 Background Thromboembolism is a life-threatening manifestation of coronavirus disease 2019 (COVID-19). We investigated a dysfunctional phenotype of vascular endothelial cells in the lungs during COVID-19. Methods We obtained the lung specimens from the patients […]

Anticoagulation in COVID-19: current concepts and controversies

Authors: http://orcid.org/0000-0002-3809-8926Atanu Chandra1, 6289Uddalak Chakraborty2, Shrestha Ghosh1, Sugata Dasgupta3 Abstract Rising incidence of thromboembolism secondary to COVID-19 has become a global concern, with several surveys reporting increased mortality rates. Thrombogenic potential of the SARS-CoV-2 virus has been hypothesised to originate from its ability to produce an exaggerated inflammatory response leading to endothelial dysfunction. Anticoagulants have remained the primary […]

What Is the D-Dimer Test?

Authors: Richard N. Fogoros, MD The D-dimer test is a blood test that indicates whether blood clots are being actively formed somewhere within a person’s vascular system. This test is most often helpful in the diagnosis of pulmonary embolus and deep vein thrombosis, but it can also be useful in diagnosing other medical conditions in which blood clots play a […]
