Figure 4

Circulating RAS mediators correlate inversely with the microvascular responses to reactive hyperemia. Circulating RAS mediators were assessed by radioimmune assay of plasma from septic subjects 24 hours following the clinical onset of organ dysfunction. Correlation analysis showed both plasma renin activity (Panel A; Spearman r = -0.52, P = 0.005) and plasma angiotensin II concentration (Panel B; Spearman r = -0.41, P = 0.03) had significant inverse linear relationships with thenar reoxygenation rates, or microvascular responses to reactive hyperemia.
