What is VENDYS?

In simple terms, VENDYS® measures vascular reactivity.

VENDYS® uses a standard arm-cuff vascular reactivity procedure, which includes a temporary occlusion of blood flow in the arm. During the cuff occlusion, the lack of blood flow (ischemia) elicits a microvascular dilative response (opening small vessels). Upon releasing the cuff, blood flow rushes into the forearm and hand, not only restoring baseline flow but also resulting in an overshoot (reactive hyperemia). This overshoot causes shear stress in the larger (conduit) arteries, which stimulates these arteries (macrovessels) to dilate and accommodate the increased blood flow.

VENDYS® monitors, records, and analyzes fingertip temperature during the above cuff occlusion and release procedure. Temperature changes serve as a surrogate marker of blood flow changes that result from vascular reactivity.

How would VENDYS benefit my patients?

Given its pivotal role in the atherogenic process, Vascular Function may be regarded as a gauge of the cumulative effects of risk factors on cardiovascular health. Using Endothelix’s proprietary DTM (Digital Thermal Monitoring) technology, VENDYS is the least expensive and easiest to use, FDA cleared, device that detects endothelial dysfunction – making subclinical CVD detectable and treatable.

With more than 6 years of research trials and dozens of peer reviewed papers and abstracts, VENDYS is now in use in clinics across the US being used as a cutting edge tool for the prevention of adverse CVD outcomes.

The Vascular Reactivity Index, also referred to as the Adjusted Temperature Recovery (aTR) Index, developed by Endothelix provides a non-invasive “window” to the cardiovascular system allowing the detection, measurement and monitoring of vital patient information such as cardiovascular health.
