VICORDER® Arterial Stiffness Model

Gold Standard Methodology – Optimal Results - for Routine Diagnostic Work and Studies

Cardio-vascular Testing Made Easy

…all in one instrument

Determination of Arterial Stiffness according to the Gold Standard

International scientific societies recommend the assessment of central aortic Pulse Wave Velocity (aPWV) by recording of pulse waves at the carotid and femoral arteries. The resulting PWVcf, defined as the ratio of pulse wave transit time and distance between these two vessels, represents the undisputed Gold Standard in determining arterial stiffness1. VICORDER® incorporates the Gold Standard determining the velocity of the pulse wave between the carotid and femoral arteries, directly, synchronously, and precisely down to the millisecond. In contrast to tonometric procedures, requiring discontinuous measurement, the synchronous recording with VICORDER® offers less operator dependence, shorter testing times, and more patient comfort. In addition the instrument can measure PWV between any two points on arms, legs, or neck, in adults, children, under virtually any condition.

Strongest Predictor of Severe Cardio-vascular Events

Highly associated to the presence and degree of atherosclerosis, PWVcf documents changes in aortic elasticity better than any other readily available parameter. Called “the probably strongest independent predictor of cardio-vascular events” by the American Heart Association2, PWVcf can be used as a direct indicator of endorgan damage, found in a variety of diseases, such as diabetes, hypertension, hyperlipidemia, or chronic kidney disease. As an example, the predictive power of Pulse Wave Velocity becomes strikingly evident in chronic kidney disease: A rise in PWVcf of 1 m/s will increase the mortality risk by almost 40%11. The independence from other cardio-vascular risk parameters enhances the predictive value of PWVcf in comparison to traditional scores, improving the assessment of individual patient risk12. A PWVcf increase can also be associated with enhanced vascular ageing, induced by an inadequate life style, mostly related to inactivity and obesity. Implemented into daily clinical practice, patients will profit from PWVcf testing by better risk stratification and therapy management.
