Short Title - Clinical Applications Measuring Arterial Stiffness
Corresponding author: Matthew Budoff MD

Keywords:  Vascular disease, Arterial stiffness, clinical, cardio-ankle vascular index, endothelial function, expert consensus

Background/Aims: 
Measuring CAVI using peripheral cuffs and a chest microphone provides several logistical advantages that are beneficial for clinical use.  It is primarily operator independent, does not require exposure of the groin area (which some tonometric methods use for femoral pulse reference points), is a very reliable measure, and automated for greater ease-of-use and reproducibility. In addition to including the more peripheral arteries of the legs, the entire aorta is represented in the CAVI measurement, whereas other measurements omit significant portions of the aorta.  
Methods:  We wrote an expert consensus document on the clinical use of CAVI. 
Results:  As arterial stiffness predicts cardiovascular risk independently of traditional risk factors, it has a significant impact on decision-making in various clinical scenarios. Several outcome studies demonstrate the robust risk associated with CAVI >8 and >9.  Recently, the Japanese Society for Vascular Failure proposed the cut-off values for CAVI: <8 for normal, ≥8 to <9 for borderline, and ≥9 for abnormal. CAVI has been applied clinically to assess arterial stiffness in patients who were diagnosed with CAD, stroke, and those at risk.  Arterial stiffness is an independent predictor of CAD, and is correlated with the severity of coronary stenosis.
Arterial stiffness, as represented by CAVI is significantly and strongly correlated with both CAC and coronary stenosis. 
Conclusion: Thus, CAVI may be used as screening tool for early prediction of obstructive CAD and plays a critical role in preventive cardiology to optimize management. CAVI may also aid in the evaluation of younger individuals with a family history of isolated systolic hypertension, given that a substantial proportion of the variability in large artery stiffness is inheritable. We suggest that CAVI is a useful frontline test, appropriate for outpatient clinics, for identifying patients who might otherwise go unnoticed for coronary vessel risk.  This proposed scenario is even more pertinent to patients with diabetes, hypertension, and kidney dysfunction, where cardiovascular risk is higher.
