The first, patented, user-independent, simple and fast, single upper-arm suprasystolic cuff-based method, suitable for daily clinical routine work. Validated invasively. Existing cardiovascular outcome studies. Does not use generalized transfer function (GTF).

User-independent, simple, single upper-arm suprasystolic cuff-based method, suitable for daily clinical routine work (both office measurement and 24-hour monitoring). The measuring algorithm validated invasively. Does not use generalized transfer function (GTF).

User-independent oscillometric ABI device, providing PWVba (brachial ankle) and estimated PWVcf (carotid femoral). None of PWVs are validated clinically.

​

*The device provides an estimation of carotid-femoral PWV from the brachial-ankle PWV using an unknown, unpublished method.

**No validation or other paper available according to Pubmed database.

User-independent, simple, fast, single upper arm cuff-based oscillometric, suprasystolic method.  SBPao was invasively validated but using standard non-invasive calibration the agreement was weak (mean difference and SD; -7±9 mmHg).

​

*No paper is available about invasive validation of AIXao.

User-independent, simple, fast, single upper arm cuff-based oscillometric, suprasystolic method. Uses non-validated generalized transfer function (GTF).

​

*PWVao correlates 99.7% with age and brachial SBP, indicating that the device does not measure real PWVao.

**No invasive validation of AIXao and SBPao.

Wrist-sensor based applanation tonometric device. Sensitive to the sensor positioning on the radial artery. Validated invasively, however, in one paper, at lower central SBP values the device overestimated the SBPao, while at higher central SBP values the device underestimated the SBPao.  Requires BP calibration. Does not use generalized transfer function (GTF).

Traditional, relatively time-consuming method with piezoelectric sensors, requires trained personnel. Invasively validated PWVcf, SBPao and AIXao. The device may overestimate the PWVao especially in cases of higher PWV, due to the simultaneous recording of carotid and femoral pressure curves, and the opposite propagation of the aortic pulse pressure waves to carotid and femoral sites. Existing several cardiovascular outcome studies.Does not use generalized transfer function (GTF).

User-independent, simple, and fast single upper-arm cuff based method for 24h measurement of peripheral and central blood pressure. Acquisition of the oscillometric pulse waves takes place during the deflation of the cuff. The algorithm uses adaptive transfer function. SBPao is validated invasively. No paper available about other stiffness parameters.

​

*No paper is available about invasive PWVao validation.

User-independent, simple and fast single upper-arm diastolic cuff pressure-based method . Unreliable PWVao measurement (ARC Solver Algorithm). PWVao correlates 99% with age and SBP indicating no real PWVao measurement. SBPao validated invasively. Uses non-validated generalized transfer function (GTF).

​

*No paper is available about invasive AIXao validation.

User-independent applanation tonometric device providing radial Aix and Central Systolic Blood Pressure (SBPao). SBPao invasively validated. Does not use generalized transfer function (GTF).

Oscillometric ABI device, providing PWVba (brachial ankle), requiring four cuffs and other sensors. During brachial-ankle PWV measurement the representation of the aorta is partial, although only the aortic PWV has prognostic value for CV endpoints. No validation paper available. Existing outcome study.

Photoplethysmographic device measuring PWVft (finger-toe) of which clinical significance has not yet been clarified, because the pulse transit time between finger and toe are influenced not only by the aorta, but also by several muscular type peripheral arteries, too, which prognostic value has not been proven. It shows week correlation with invasively measured aortic PWV.

User-dependent and time-consuming applanation tonometric device with ECG gating for PWVao measurement. Its use requires trained personnel. Aortic PWV validated invasively. Does not use generalized transfer function (GTF).

​

*No paper is available about invasive SBPao and AIXao validation.

User-independent, simple and fast single upper-arm diastolic cuff pressure-based method uses the same algorithm (ARCSolver) available in Mobil-o-Graph. For this reason, we refer to the relevant scientific papers of Mobil-o-Graph. Unreliable PWVao measurement (ARC Solver Algorithm). PWVao correlates 99% with age and SBP indicating no real PWVao measurement. SBPao validated invasively. Uses non-validated generalized transfer function (GTF).

​

*No paper is available about invasive AIXao validation. 

Time-consuming user-dependent applanation tonometric method with ECG gating for PWVao measurement. Its use requires trained personnel. Existing cardiovascular outcome studie. Uses invasively validated generalized transfer function (GTF). Invasively validated AIXao and SBPao. PWVao is also validated invasively, however the limit of agreement according to Bland-Altman plot turned to be high -3.8 m/s (-2SD) and 4.1 m/s (+2SD).
