To investigate the determinants of endothelial cell damage in hypertensive elderly patients, we measured the plasma von Willebrand factor (vWF) levels by a recently developed enzyme-linked immunosorbent assay using monoclonal antibody for the functional epitope. Plasma vWF level was markedly increased in the elderly normotensive subjects (n=42) than in younger normotensive subjects (n=39) (127 vs 88%, p<.0001), and was further increased in elderly hypertensive subjects (n=68) (148%, p<.05 vs elderly normotensives). The vWF level was positively correlated with body mass index in younger normotensive subjects (r=0.41, p<.01), with systolic blood pressure (BP) in elderly normotensive subjects (r=0.41, p<.01), and with age (r=0.44, p<.001) and fibrinogen level (r=0.37, p<.01) in elderly hypertensive subjects. In elderly hypertensive subjects (n=150), vWF level had a stronger positive correlation with 24-hr systolic BP measured (r=0.41, p<.0001) by ambulatory BP monitoring than with clinic systolic BP (r=0.33, p<.0001). In conclusion, in hypertensive elderly patients, endothelial cell damage increases with systolic BP and fibrinogen levels, indicating a prethrombotic condition.
