Arterial Stiffness

Hungary's "tensio arteriograph" - a simple way of examining our veins

Cardio-vascular disease is the leading cause of death in Hungary and much of the rest of the world. Problems are often detected too late because many people do not suffer obvious symptoms. Even suspect cases can be difficult to confirm. But that may soon be history thanks to a new device invented by Hungarian doctor Miklos Illyes.
The "tensio arteriograph" is the first and so far only device that provides us with a fast and easy way of obtaining cardiac data that in the past could only be obtained through complicated and sometimes painful screenings.
"The medical profession was lacking a proper method to determine these data, called 'arterial stiffness parameters', namely, the augmentation index and the pulse rate velocity of the human aorta. So, this method before was determined by very specific procedures, very difficult methods, which needed a lot of time and a lot of expert knowledge of how to perform the examination."
Tensio arteriograph Says, doctor Miklos Illyes, the inventor of the tensio arteriograph. So how does it work? It's much simpler than one might expect. The arteriograph detects the condition of our veins in a procedure that's just as easy as taking our blood pressure.
"We discovered a new method how to assess the so-called arterial stiffness non-invasively with a very fast method, which needs only two minutes to determine the arterial age of the patient. This novelty consists of the fact that we use a simple cough to determine important central human dynamical parameters. This makes it possible for us to use this method for everyday practice and to screen the patient for arteriosclerosis. We do feel that in a few years, this kind of method will be used generally not only to check blood pressure but to have much more information about arterial stiffness beyond blood pressure measurement."
Dr. Laszlo Tisler of the St. Imre Hospital in Budapest was one of the first physicians to use it:
"My experience over all is very positive. It uses a very new way of assessing the compliance of large blood vessels. This information is substantial because it is associated with the survival of our patients - in particular, with patients of higher cardiovascular risk. The information this device provides is extremely helpful in those with high risk, and this may add new information, information on compliance of the vessel, or stiffness of the vessel, may provide information on those who have no other risk factors and this may be a very early sign of cardiovascular risk."

Arterial Stiffness

Invasive validation of a new oscillometric device
(Arteriograph) for measuring augmentation index, central
blood pressure and aortic pulse wave velocity

Background The importance of measuring aortic
pulse wave velocity (PWVao), aortic augmentation
index (Aix) and central systolic blood pressure
(SBPao) has been shown under different clinical
conditions; however, information on these
parameters is hard to obtain. The aim of this study
was to evaluate the accuracy of a new, easily applicable
oscillometric device (Arteriograph), determining these
parameters simultaneously, against invasive
measurements.
Methods Aortic Aix, SBPao and PWVao were measured
invasively during cardiac catheterization in 16, 55 and
22 cases, respectively, and compared with the values
measured by the Arteriograph.
Results We found strong correlation between the invasively
measured aortic Aix and the oscillometrically measured
brachial Aix on either beat-to-beat or mean value per patient
basis (rU0.9, P<0.001; rU0.94, P<0.001), which allowed
the noninvasive calculation of the aortic Aix without using
generalized transfer function. Similarly strong correlation
(rU0.95, P<0.001) was found between the invasively
measured and the noninvasively calculated central SBPao;
furthermore, the BHS assessment of the paired differences
fulfilled the ‘B’ grading. The PWVao values measured
invasively and by Arteriograph were 9.41W1.8 m/s and
9.46W1.8 m/s, respectively (meanWSD); furthermore, the
Pearson’s correlation was 0.91 (P<0.001). The limits of

Arterial Stiffness

Anew oscillometric method for assessment of arterial stiffness:

Introduction Pulse wave velocity (PWV) and augmentation
index (AIx) are parameters of arterial stiffness and wave
reflection. PWV and AIx are strong indicators for
cardiovascular risk and are used increasingly in clinical
practice. Previous systems for assessment of PWV and AIx
are investigator dependent and time consuming. The aim of
this study was to validate the new oscillometric method
(Arteriograph) for determining PWV and AIx by comparing it
to two clinically validated, broadly accepted tonometric and
piezo-electronic systems (SphygmoCor and Complior).
Design and method PWV and AIx were measured up to five
times in 51 patients with the SphygmoCor, Complior and
Arteriograph. In 35 patients, the measurements were
repeated after 1 week in a second session using the
same protocol.
Results The correlations of the PWV as assessed with the
Arteriograph with the values obtained using the
SphygmoCor (rU0.67, P < 0.001) and the Complior
(rU0.69, P < 0.001) were highly significant. Variability and
reproducibility for PWV were best for the Arteriograph,
followed by Complior and SphygmoCor. AIx (SphygmoCor

Abstract
Aims: In a project of the National Research Program of Hungary, we studied if oscillometric signals received during an oscillometric BP measurement contain any information about arterial hemodynamics
Materials, Methods: We have developed a research tool by which not only SBP, DBP, HR data, but the complete oscillometric signals were stored and transmitted telemedically to our computer center from the home of 650 patients who performed BP measurements at least 4 times a day, for at least 1 month. Through this a large database was collected, containing more than 1700000 oscillometric pulse curves and the relevant clinical data of patients. For data mining we used Kohonen's self-organising map method. Non-invasively recorded oscillometric curves from the upper arm cuff were validated by the simultaneously recorded intraarterial pressure curve of brachial artery.
Results: Our researches showed that oscillometric pulse curve of the brachial artery is identical to the intraarterial pressure curve if the cuff was inflated to suprasystolic pressure, preferably 35 mmHg above the SBP. Thus the early and the late systolic pressure peak, the closing incisure of the aortic valve can be recognizable, and several hemodinamical parameters could be calculated.
By using the mentioned results of basic researches, a new instrument, the TensioClinic Arteriograph was developed, by which the following parameters could be measured within 2 minutes, by using a simple upper arm cuff:
SBP, DBP, HR, MAP, PP, augmentation index (AIx), normalized augmentation index to 80/min heart rate (AIx80), return time of the pulse wave of the aorta (RT), pulse wave velocity (PWV) of the aorta, length of the cardiac cycle, area of systolic (SAI) and diastolic (DAI) part of pulse curve.
Validation studies of the new method to control the accuracy of measured AIx and PWV showed high correlations (R = 0,76 and R = 0,8) with values measured with other non-invasive methods (Sphygmocor and Complior) respectively.
Conclusions: Due to the swiftness, simplicity and good reproducibility of this method and apparatus, the non-invasive assessment of the most important hemodynamical parameters and arterial stiffness had become available for population screening, opening a new window in the detection of the early phase of the athero- and arteriosclerosis, and thus it can play an important role in the reduction of the CV morbidity and mortality.
