Persistent endothelial dysfunction in post-COVID-19 syndrome and its associations with symptom severity and chronic inflammation
Persistent endothelial dysfunction in post-COVID-19 syndrome and its associations with symptom severity and chronic inflammation

Long Covid patients exhibited persistent endothelial dysfunction.

This was indicated by lower venular flicker-induced dilation (vFID), narrower central retinal artery equivalent (CRAE), and lower arteriolar-venular ratio (AVR).

“Our results demonstrate that prolonged endothelial dysfunction is a hallmark of PCS, and impairments of the microcirculation seem to explain ongoing symptoms in patients.”
