Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to define the repeatability and reproducibility of quantifying flow-mediated dilation (FMD) of the brachial artery (BA) using the AngioDefender (AD) methodology.

Repeatability will be assessed by repeat AD testing of the same subject 1 hour apart, using the same AD device and operator.

Reproducibility will be assessed by comparing FMD scores obtained for the same subject, but using different AD devices and operators.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

AngioDefender

The AngioDefender device uses a novel, proprietary software algorithm to analyze pulse wave amplitude data collected before and after brachial artery occlusion by a standard upper arm pneumatic blood pressure cuff. The procedure is non-invasive and does not employ ultrasound.
