We evaluated six patients with laboratory-confirmed SARS-CoV-2 infection
with a mean age of 75.8 years. Five of them were female (83.3%); the
average mean arterial pressure was 87 mmHg (normal values 70-110 mmHg).
Blood sample tests revealed an inflammatory state in all patients, with
high plasma levels of C-reactive protein, fibrinogen, ferritin, LDH, and
D-dimer. Overall, four patients were positive for endothelial
dysfunction, with RHI values between 1.13-1.56 (average value 1.32,
normal values >1.67) [Figure 1]; in one of the two
negative patients the reported RHI value was slightly above the cutoff
(1.72).
