COVID-19 Associated Endothelial Dysfunction Study

SARS-CoV-2 enters human cells through the binding of the spike protein with angiotensin converting enzyme-2 (ACE2), a membrane receptor highly expressed in immune or non-immune cells, and in many organs, including lungs and endothelial cells. In COVID-19 disease, the infection of endothelial might cause an acute endothelial dysfunction. The objective of this study is to demonstrate that patients COVID19 (+) hospitalized in ICU present an acute endothelial dysfunction (compared with COVID19 (-) also hospitalized in ICU). This acute endothelial dysfunction could lead to organ failure, systemic immune dysregulation and thrombosis.
