Introduction: The new severe acute respiratory syndrome coronavirus 2 has led to an unprecedented global health crisis. The high rate of thromboembolic complications in these patients is notorious, but the tools to estimate the risk of these complications are still preliminary. Objective: To describe the rate of thromboembolic events in patients admitted for COVID-19 in a tertiary hospital in Belém - Pará. Methodology: This is a retrospective cohort study that included data from medical records of patients admitted for COVID-19 at the Hospital das Clínicas Gaspar Vianna (HCGV), from March 1st to October 31st, 2020. The following variables were evaluated: demographic data, cardiovascular risk factors, thromboembolic complications, medications, among others. Statistical analysis using the chi-square test, p <0.001. Results: 203 patients were included, mostly male (61.4% *), with a mean age of 58.4 years and with previous morbidities (87.2% *). The cumulative rate of thromboembolic events was 22.2%, with deep vein thrombosis being the most common (9.4%). Mainly treated with antithrombotic drugs (91.6% *), the most used were heparins (86.7% *). Conclusion: Patients hospitalized for COVID-19 in a tertiary institution in the state of Pará were predominantly elderly, male and with multiple morbidities, which reflected a high cumulative rate of thromboembolic events, especially deep vein thrombosis.
