Covid 19 Früherkennung und Therapiebestimmung

In use with COVID-19

Research results say: COVID-19 leads to vascular inflammation, heart attack, stroke

Currently multiple research results describe COVID-19 as less of a lung disease and more of a systemic vascular disease that may lead to strokes. Accordingly, the coronavirus affects not only the respiratory tract, but also the neurovascular unit, which supplies vital organs – the brain, kidneys and lungs.

SARS-CoV-2 infection can be particularly dangerous in patients whose vascular function is already impaired by pre-existing conditions. This explains the typical clinical picture by causing circulatory disorders in the heart, as well as pulmonary embolism and vascular occlusions in the brain and kidneys. These can eventually lead to fatal multi-organ failure. The scientists emphasize that it is mainly multi morbid patients with cardiovascular risk factors such as high blood pressure, high blood lipids (hypercholesterolaemia), high blood sugar levels (Diabetes mellitus) and patent foramen ovale (PFO) who are seriously affected by COVID-19.

TCD for early detection and therapy determination

With the help of TCD screening, the risk of vascular diseases can be diagnosed in COVID-19 patients and a targeted decision about their therapy and treatment can be made.

If the coronavirus causes vascular inflammation (vasculitis), the inflammatory reaction leads to vascular narrowing with relevant cerebral blood flow velocities (CBFV) changes. An intracranial routine examination can assist in diagnosis of vasculitis by following proximal cerebral vascular abnormalities.

Emboli detection and a TCD-based PFO test can indicate an increased risk of thrombosis and stroke in COVID-19 patients. Therefore, a therapy can be determined more precisely and the patient can be protected against possible consequential damage with appropriate measures.

Since inflammation of the vascular system has a serious influence on the blood flow velocities, the course of the disease and therapy of a patient affected by COVID-19 can be controlled and optimized using the Neuromonitoring Analysis (NMA).
