Insights
COVID-19 causes a dramatic hypercoagulable state, leading to arterial thrombosis. D-dimer levels in COVID-19 patients did not reliably predict clot burden or future thrombosis risk.
Area of Science:
- Cardiology
- Hematology
- Infectious Diseases
Background:
- COVID-19, caused by SARS-CoV-2, presents with significant hypercoagulability.
- The prothrombotic state in COVID-19 is more pronounced than typically seen in sepsis.
Observation:
- Three cases of arterial thrombosis with substantial clot burden requiring urgent intervention are presented.
- Clinical experience suggests D-dimer levels may not correlate with clot burden in COVID-19 patients.
Findings:
- The hypercoagulable state in COVID-19 appears to be a direct prothrombotic effect of the disease.
- D-dimer levels showed poor correlation with clot burden and future thrombosis risk in observed cases.
Implications:
- Rethinking current practices for deep venous thrombosis (DVT) prophylaxis in COVID-19 patients is necessary.
- Further research is needed to identify reliable markers for thrombosis risk assessment in COVID-19.
- Understanding the mechanisms of COVID-19-induced hypercoagulability is crucial for effective patient management.
Abstract:
Coronavirus disease of 2019 (COVID-19) is a disease caused by the novel coronavirus SARS-CoV-2, which is characterized by a multitude of clinical abnormalities, including hypercoagulability. Although thrombosis is commonly observed in sepsis, the hypercoagulable state associated with COVID-19 is much more dramatic and may not be related to either the severity of the disease or the D-dimer levels. It may be due to a prothrombotic state induced by the disease itself. We report three cases of arterial thrombosis with a significant clot burden requiring urgent medical and surgical intervention. It is now a common practice to initiate anticoagulation for deep venous thrombosis (DVT) prophylaxis based on the D-dimer level in hospitalized patients with COVID-19. However, in our clinical experience, D-dimer levels did not correlate well with the clot burden or the risk for future thrombosis.
