The frequency of thromboembolic events in patients with coronavirus disease is high, however it is still unknown what is the appropriate way to identify people at higher risk of thrombotic complications and define who can benefit from a more aggressive treatment, beyond the standard thromboprophylaxis. A large proportion of critically ill patients with coronavirus have a hypercoagulable thromboelastography profile with damage related to fibrinogen and platelet function; most patients have a high maximum amplitude on thromboelastography. A review of thromboelastograms of 11 critically ill patients due to SARS-CoV-2 was made to characterize their coagulation status. A 36.36% hypercoagulability was found in thromboelastography, mainly with native citrate, despite treatment with low molecular weight heparin at therapeutic doses. The predominant hypercoagulable profile was not associated with platelet function since the MA (maximum amplitude) remained within normal limits.
