RT Journal Article SR Electronic T1 Recurrent chronic thromboembolic disease despite optimal anticoagulation in setting of recent COVID-19 infection JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e238733 DO 10.1136/bcr-2020-238733 VO 14 IS 1 A1 Vittorio Romeo Terrigno A1 Daniel Anthony Ricketti A1 Pranav Patel A1 Satyajeet Roy YR 2021 UL http://casereports.bmj.com/content/14/1/e238733.abstract AB We present a case of a 38-year-old man with a history of chronic thromboembolic pulmonary hypertension on therapeutic anticoagulation and recent hospitalisation for COVID-19 disease who was hospitalised for recurrent acute pulmonary embolism despite therapeutic anticoagulation with warfarin (International Normalized Ratio (INR) of 3.0). Our case highlights the hypercoagulable state associated with COVID-19 disease and the absence of standardised approaches to anticoagulation treatment for this population.
