Ambulatory arterial stiffness index (AASI) is a novel estimate of arterial stiffness, which independently predicts cardiovascular mortality, even in normotensive individuals. Additionally, other markers derived from ambulatory blood pressure (BP) monitoring, including variability, pulse pressure, nocturnal dipping, and morning BP surge, have all been shown to be predictive of end-organ damage and cardiovascular disease. Exaggerated cardiovascular reactivity to sympathoexcitatory stimuli may also predict future incidence of hypertension. The purpose of this investigation was to test the hypothesis that AASI and other derivations of ambulatory BP, including pulse pressure, 24-h blood pressure variability, dipping, and morning surge, would be correlated with the pressor response to common physiological stress maneuvers.
