Ambulatory Arterial Stiffness Index (AASI)

Purpose:

To estimate the stiffness of a patient's arterial tree by calculating the ambulatory arterial stiffness index (AASI).

Specialty:

Interventional Cardiology, Cardiac Electrophysiology, Geriatric Medicine - Family Practice, Geriatric Medicine - Internal Medicine, Vascular Medicine

Objective:

risk factors, other testing, severity, prognosis, stage

ICD-10:

I10, I11, I12, I13, I15, I70

Description:

The ambulatory arterial stiffness index (AASI) is a measure of the stiffness of the arterial system. Arterial stiffness shows a nonlinear relationship to distending pressure, with stiffness increasing exponentially as the distending pressure increases linearly. A high AASI indicates an increased risk for cardiovascular mortality.
