Professor Toby Richards, our Clinical Lead for Vascular Surgery, and his colleagues have been investigating the functional recovery of non-hospitalised long-COVID patients. In a recent study, they took blood samples from patients 3 months after acute COVID-19 infection and followed up with further assessment after 6 months. The patients showed a spectrum of multiple persistent biochemical pathophysiology, suggesting that their metabolic phenotyping approach could be deployed for multi-system functional assessment of individual post-acute COVID-19 patients.
