SARS-CoV-2 increases the risk of blood clots – naturopathy & naturopathy specialist portal

Relationship between COVID-19 and blood clots identified

Worldwide, COVID-19 is treated as a primary lung disease, but complications from blood clots are also repeatedly observed in people with COVID-19. This indicates that respiratory failure in COVID-19 is not solely due to the development of acute respiratory distress syndrome, but that microvascular thrombotic processes may play a role.

The University of Edinburgh’s recent investigation found that microvascular thrombotic processes appear to play an important role in the development of respiratory failure in COVID-19. The results of the study were published in the English-language journal “Radiology“Published.

Thrombotic complications in COVID-19 sufferers?

The study described the prevention, diagnosis and treatment of complications from blood clots in patients with COVID-19. Concerns about thrombotic complications have increased based on recent reports that show a strong association between elevated D-dimer levels and poor prognosis.

Is COVID-19 really a primary lung disease?

Worldwide, COVID-19 is treated as a primary lung disease. However, from analysis of all available current medical, laboratory chemical and imaging data on COVID-19, it became clear that the symptoms and diagnostic tests cannot be explained by impaired lung ventilation alone, the researchers report.

Respiratory insufficiency in COVID-19 is not solely due to acute respiratory distress syndrome

Recent observations suggest that respiratory failure in COVID-19 is not solely due to the development of acute respiratory distress syndrome, but that microvascular thrombotic processes may play a role. This can have important consequences for the diagnostic and therapeutic management of those affected. The research group explains that there is a close relationship between D-dimer values, the course of the disease and features of the chest CT that indicate venous thrombosis.

The prothrombotic and thrombotic state of COVID-19 must be considered

In addition, various studies in COVID-19 sufferers have shown a very strong association between increased D-dimer levels and a serious illness or poor prognosis. The researchers emphasize that careful attention needs to be paid to the initial diagnosis and treatment of the prothrombotic and thrombotic condition, which can occur in a significant percentage of those affected by COVID-19.

COVID-19 syndrome gradually affects all organs in the body

Imaging and pathological studies confirmed that COVID-19 syndrome is a thrombotic inflammatory process that initially affects lung perfusion, but affects all organs of the body in succession, the researchers report. Another study came to similar results and showed that the novel Coronavirus causes systemic vascular inflammation.

When is anticoagulant therapy appropriate?

This highly thrombotic syndrome leads to macrothrombosis and embolism. Therefore, strict thrombosis prophylaxis, adequate imaging monitoring with early anticoagulant therapy in the event of suspected venous thromboembolism are appropriate, the researchers advise.

What measures should be taken?

Recommendations for diagnostic and therapeutic management, which vary depending on the patient’s symptoms and risk profile, include prophylactic dose heparin, chest CT, pulmonary CT angiography, and routine D-dimer testing, the research group continues.

Connection between COVID-19 and pulmonary embolism?

Findings have also been made that more specifically relate COVID-19 to pulmonary embolism. When analyzing 106 pulmonary CT angiograms performed for COVID-19 patients over a one-month period in a tertiary care center in France, 32 patients (30 percent) had acute pulmonary embolism. This rate of pulmonary embolism is much higher than usual in critically ill patients without COVID-19 infection (1.3 percent) or in emergency room patients (three to ten percent).

COVID-19 is more than a lung infection

The researchers conclude that COVID-19 affects the vascular system of the lungs and other organs and is associated with a high risk of thrombosis with acute life-threatening events that require adequate treatment. (as)
