Objective

Pulsewave velocity (PWV) and augmentation index, both parameters correlated to arterial stiffness, are powerful indicators for cardiovascular risk, especially in hypertension, diabetes mellitus, hypercholesterinemia and renal insufficiency. Methods currently used to assess PWV, are expensive, invasive or complex to handle.

Design and Method

PWV measurements were performed in 42 Patients with a new fingerplethysmographic device (Pulse Trace, Micro Medical Limited). Simultaneously aortic pulsewave velocity was assessed with the well validated applanation tonometrie method (SphygmoCor, AtCor medical) at femoral and carotid artery sites. Additionally, pulsewave analysis to assess the augmentation index was taken at the radial artery.

Results

In relating fingerplethysmographically assessed PWV to augmentation index we found a correlation which shows an increase of PWV in parallel to an increase of augmentation (R²=0,42). Comparing PWV assessed by the well validated applanation tonometrie method to the fingerplethysmographically method, respectively, there was a correlation of R²=0,74.

Conclusion

We have shown a correlation between the well established applanation tonometrie and the fingerplethysmographic methods, concerning both puslewave velocity to each other and to augmentation index. The non-invasive and easy to handle fingerplethysmographic device could be a method to indicate cardiovascular risk in the daily routine. Further studies are necessary to explore the clinical relevance.
