Tests and Protocols

=

Carotid IMT

Carotid duplex imaging is used to measure intima-media thickness (IMT), a measure of subclinical cardiovascular disease (CVD) which has been shown to correlate with CVD risk factors.

=

Vascular Stiffness

The cause of the increased vascular stiffness with age in humans is not known.

=

Endothelial Function

Changes in arterial function and structure are thought to precede measurable atherosclerosis and may be the earliest markers for disease potential.

=

Other Noninvasive Measures

The ankle-arm index (AAI) is a standard noninvasive measure used in research that correlates with CVD events, CVD mortality and overall mortality in many populations.
