Coronary Thrombosis in a Patient with COVID-19 Who Was on Anticoagulant Therapy

Introduction: covid-19-related thrombotic events are associated with an increase inthe risk of mortality and morbidity. considering the research on the pathophysiology ofthe disease, the significance of cardiac thrombosis is being more recognized.case presentation: this study aimed to present the first case report of a left maincoronary artery (lmca) thrombosis due to covid-19 infection in a middle-aged malewith a mechanical valve on anticoagulant therapy and with an international normalizedratio (inr) within the therapeutic range.conclusions: the results suggested that the therapeutic inr range may need to be higher(about 3.5) during the acute phase of covid-19 infection to prevent thrombotic eventsamongst patients with covid-19 who are on anticoagulant therapy. however, furtherevidence is required to determine the target range for inr in patients with covid-19who are on anticoagulants prior to infection.
