Response to Dipping Deeper Into the Ambulatory Arterial Stiffness Index

Dipping deeper into the ambulatory arterial stiffness index.

To the Editor: Methodologic and conceptual issues seriously weaken the conclusions of Schillaci et al1 on the ambulatory arterial stiffness index (AASI), as published in the May 2007 issue of Hypertension. Schillaci et al1 reported that, in 515 untreated patients, AASI depended on the nocturnal blood pressure fall. We confirmed this observation in our Flemish population study.2 The correlation ...

Ambulatory arterial stiffness index: determinants and outcome.

OBJECTIVES We hypothesized that one minus the slope of diastolic on systolic blood pressure in individual 24-h ambulatory blood pressure recordings (ambulatory arterial stiffness index) might reflect arterial stiffness and predict cardiovascular mortality. METHODS In volunteers and a population recruited in China, we studied concordance between ambulatory arterial stiffness index and establis...

Ambulatory arterial stiffness index: rationale and methodology.

OBJECTIVES Increased arterial stiffness is associated with the development of cardiovascular disease and may even predict its development at an early stage. Increased pulse pressure is seen as a marker of increased arterial stiffness and can be readily measured by ambulatory blood pressure monitoring. We propose another surrogate measure of arterial stiffness derived from ambulatory blood press...

Determinants of the ambulatory arterial stiffness index regression line.

Interstudy variability in the ambulatory arterial stiffness index.

Interstudy Variability in the Ambulatory Arterial Stiffness Index To the Editor: In 2006, Li et al1 proposed the ambulatory arterial stiffness index (AASI) as a novel marker for arterial stiffness. AASI is derived from the linear relationship between systolic blood pressure and diastolic blood pressure observed using 24-hour ambulatory blood pressure monitoring. The literature published on this...
