original, patented oscillometric method

The Arteriograph
Arteriograph is a new diagnostic method that can offer reliable and easily understandible information for the patient about endothelial function, central blood pressure and large artery characteristics, which independently and all together are significant determinants of cardiovascular risk.
Medical research over the past decade has provided new possibilities for identifying early stage arterial stiffening via testing of large artery compliance. A significant number of broad, international studies and conclusions, and international studies designated as “evidence-based medicine” support the effectiveness of arterial stiffness related to cardiovascular disease and its prediction. Previously these important characteristics could only be tested under clinical conditions. As a result of the change in approach in this area, devices that are easy and safe to use have appeared, which are able to measure the parameters that indicate arterial function.
The Arteriograph, developed in Hungary and patented in over 30 countries, can measure in a procedure performed on a patient, similarly to a blood pressure measurement, the biological characteristics of the condition of the arteries, which independent of the other well-known classic risk factors (age, sex, blood pressure, cholesterol level, smoking habits), reliably indicates the cardiovascular condition of an asymptomatic patient and his/her risk level, and also assists in adjusting existing blood pressure reduction therapy to an exact and individualized level.

This original, patented oscillometric method, which has also been proven invasively, obtains information from the analysis of the pulse pressure curve registered in the upper arm. The special, so-called stop-flow method, i.e. the complete occlusion of the brachial artery eliminates the distortion of the pressure curve, so that the pressure curves are clearly recognizable and suitable for analysis. The occlusive measurement period lasts just a few seconds. The analytic software does not employ a mathematically generalized transfer function. The determination of the position and the amplitude of the reflective wave enable simultaneous and simple determination of pulse wave velocity, the augmentation index and the central blood pressure, as well as complementing the traditional blood pressure measurement data (systolic, diastolic blood pressure, arterial medial pressure, pulse) with further hemodynamic parameters.

Text
Einleitung: Der Augmentations-Index (AIx) quantifiziert die Pulswellen-Reflexion, ist ein direktes Ma゚ f・ Gefalter, ein indirektes Ma゚ f・ arterielle Gefsteifigkeit und eng verkn・ft mit kardiovaskulem Gesamt-Risiko. K・zlich wurde eine neue Methode entwickelt, welche aus oszillometrisch am Oberarm aufgezeichneten Blutdruckkurven den AIx analysiert. Ziel unserer Studie ist, die herkmliche, als Goldstandard angesehene, applanationstonometrische (SphygmoCor) mit der neuen oszillometrischen Methode, die Augmentation zu bestimmen, (Arteriograph) zu vergleichen.
Material und Methoden: Bei 41 Patienten und Probanden im Alter von 22-74 Jahren wurde jeweils 2 mal tonometrisch mit SphygmoCor (AtCor Medical, Sydney) sowie 4mal oszillometrisch mit Arteriograph (TensioMed, Budapest) der AIx bestimmt. Anschlie゚end wurden die Korrelationen zueinander sowie zum Alter berechnet.
Ergebnisse: Die Korrelation des AIx von Applanationstonometrie zu oszillometrischer Methode ist hoch signifikant mit r=0,809 (p<0,0001) und rイ=0,655. Zum Alter waren beiden Methoden nlich hoch signifikant mit r=0,76 (SphygmoCor) und r=0,72 (Arteriograph).
Schlussfolgerung: Die oszillometrische Bestimmung der Augmentation mittels des sehr einfach anzuwendenden, Untersucher-unabhgigen und kosteng・stigen Arteriograph birgt ein gro゚es klinisches Potential zur kardiovaskulen Risikostratifizierung.

Aerweial 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."
