COVID-19 as a Vascular Disease: Lesson Learned from Imaging and Blood Biomarkers
1Department of Surgery, Vascular Disease Centre University Hospital of Ferrara, 44124 Cona (Fe), Italy.
Insights
COVID-19 is increasingly recognized as a vascular disease, with blood clots being a key factor in severe complications. Utilizing vascular biomarkers and ultrasound imaging is crucial for early detection and management of thromboembolism.
Area of Science:
- Cardiovascular Medicine
- Pulmonology
- Vascular Biology
Background:
- COVID-19, initially viewed as primarily interstitial pneumonia, presents significant vascular complications and mortality.
- Blood clots (thromboembolism) are now understood as a unifying factor in many unexplained COVID-19 symptoms.
Discussion:
- Cardiovascular biomarkers like D-dimer and troponin are powerful prognostic indicators for COVID-19 patients.
- These markers signal the need for timely and aggressive interventions to prevent arterial/venous thromboembolism and myocardial infarction.
- Ultrasound imaging of the lungs and peripheral vasculature offers longitudinal monitoring capabilities, unlike PCR or CT scans.
Key Insights:
- COVID-19's vascular pathology is central to its severe manifestations.
- D-dimer and troponin levels are critical for assessing prognosis and guiding treatment intensity.
- Ultrasound provides a safe, repeatable method for monitoring vascular changes in COVID-19.
Outlook:
- Future COVID-19 management strategies should prioritize vascular assessment.
- Integrating targeted imaging and vascular biomarkers can improve patient outcomes.
- A shift in perspective from purely respiratory to vascular disease is essential for pandemic response.
Abstract:
COVID-19, a disease initially thought to be prominently an interstitial pneumonia with varying degrees of severity, can be considered a vascular disease with regards to serious complications and causes of mortality. Quite recently, blood clots have emerged as the common factor unifying many of the symptoms initially attributed without an explanation to COVID-19. Cardiovascular biomarkers and particularly, D-dimer and troponin appear to be very powerful prognostic markers, signaling the need for earlier and more aggressive interventions and treatments in order to avoid and/or minimize arterial/venous thromboembolism and myocardial infarct. The ultrasound imaging patterns at both the lung and peripheral vascular level can also be very useful weapons that have the advantage of being able to monitor longitudinally the clinical picture, something that real-time PCR/nasopharyngeal swab is not able to do and that CT can only pursue with significant radiation exposure. A lesson learned in the early phase of the COVID-19 pandemic suggests quitting and starting again with targeted imaging and blood vascular biomarkers.
