Lasting Microvascular Damage in Long COVID Patients: A Sublingual Microcirculation Study

A recent study called “Persistent capillary rarefication in long COVID syndrome”, published in the journal ‘Angiogenesis’, provides crucial insights into the persistent microvascular changes in Long COVID patients. This study’s findings highlight the long-term impact of COVID-19 on small blood vessels, even 18 months after infection. Here’s a summary of its key points: Conclusions: The findings strongly suggest persistent capillary rarefaction, or a reduction in the number of capillaries, in Long COVID patients even 18 months after the initial infection. The long-term reversibility of this microvascular damage remains uncertain. The study emphasizes the need for further research to understand the…
