Thromboembolism in Patients With Coronavirus Disease-2019

Microvascular and macrovascular thrombotic complications, including arterial and especially venous thromboembolism (VTE), seem to be common clinical manifestations of coronavirus disease-2019 (COVID-19), particularly among hospitalized and critically ill patients.[1–4] Pooled analyses have helped in providing aggregate estimates of thrombotic events.[4,5] In a recent systematic review and meta-analysis, the overall incidence of VTE among inpatients with COVID-19 was estimated at 17% (95% confidence interval [CI]: 13.4 to 20.9), with variation based on study design and method of ascertainment; there was a four-fold higher incidence rate in patients in the intensive care units (ICUs) compared with non-ICU settings (28% vs. 7%).[6] In addition, postmortem studies show frequent evidence of microvascular thrombosis in patients with COVID-19.[7,8] The influence of these events on mortality rates remains unknown.[9]
