Arteriograph- Comprehensive cardiovascular risk assessment in only 3 minutes!

Why you should buy an Arteriograph

Arteriograph- Comprehensive cardiovascular risk assessment in only 3 minutes! - A medical breakthrough in early diagnostics of atherosclerosis!
A big problem today is that many individuals with high risk of cardiovascular diseases otherwise have normal values; normal blood pressure, blood lipids and resting-EKG. The catastrophe strikes without any prior warning. The Arteriograph is an evidence based, fast, easy, noninvasive and user independent way of assessing cardiovascular risk. For the first time one have a good chance of finding high risk patient before it is too late.
1. Screening of early atherosclerosis among ”healthy” individuals. Only the Arteriograph is useful for this. The Arteriograph gives an overall picture of the risk of assessing cardiovascular disease.
2. Evaluating the effects of treatments (drugs, nutritional supplements and lifestyle changes etc) on the vascular functions among patients with established atherosclerosis (CAD, POST MI, STROKE, PAD)
3. Is it not enough to check the blood lipids and blood pressure to prevent atherosclerosis and thereby strokes? No, 40-60% of patients with stroke or heart attacks do not have any know abnormal values such as high amount of blood lipids or high blood pressure (Johns Hopkins White Papers, Coronary Heart Disease - 1998, etc). They also have normal blood glucose values, resting-EKG, are non-smokers and have a healthy diet. Up until now it has been impossible to find there individuals.
4. Todays metods of assessing cardiovascular risk (SCORE, Framingham) all have limits. They do not take into account important factors such as lack of physical activity, overweight, psychological factors or previous cardiovascular circumstances. (Simon, A. and Levenson, J.: May subclinical arterial disease helps to better detect and treat high-risk asymptomatic individuals? J Hypertension 2005, 23: 1939-1945)
5. In most cases, lowering the blood pressure is not enough to avoid early death. Individuals who can lower both their arterial stiffness and blood pressure have a much greater chance of a longer life.Circulation 2001;103:987
6. The Arteriograph is mobile and easy to use. The screening is fast, comfortable, harmless and user independent. It takes only a few minutes and can be described as a computerized blood pressure measurement.
7. Today´s other available methods are hard to use, expensive, and requires an adequate educated staff. In the future, the Arteriograph may replace the regular blood pressure measurement as it is just as easy but gives much more information.

The Arteriograph is intended for DAILY USE at your clinic to measure AIx, PWV and Central blood pressure etc.

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.

Renal Denervation Improves Blood Pressure And Arterial Stiffness

Renal Denervation Improves Blood Pressure And Arterial Stiffness

Munich, Germany – August 27 2012: Renal denervation improves blood pressure and arterial stiffness in patients with therapy resistant hypertension, according to research presented at ESC Congress 2012 by Mr Klaas Franzen from the University Hospital of Schleswig-Holstein. The findings suggest that renal denervation regenerates blood vessels and could reduce cardiovascular events.

Malignant arterial hypertension was historically treated with surgical thoracolumbar splanchnicectomy, a type of sympathectomy treatment that was introduced in 1938. "A significant reduction in blood pressure response was observed in at least half of the patients who underwent splanchnicectomy," said Mr Franzen. "But the treatment led to severe adverse events such as orthostatic hypotension, anhidrosis and intestinal disturbances. After the discovery of effective antihypertensive drugs, splanchnicectomy became neglected and disregarded over time."
In 2009 the concept of sympathectomy was reintroduced with intravasal catheter-based percutaneous renal sympathetic denervation (RDN) used in patients suffering from resistant arterial hypertension. Recent publications have shown that RDN significantly lowers systolic and diastolic peripheral brachial blood pressure by 32/12 mmHg after 6 months.
Mr Franzen said: "RDN with radiofrequency energy has several important advantages over surgical splanchnicectomy: it is a minimally invasive procedure without significant systematic side effects, it is well tolerated, and recovery times are short."
Arterial hypertension can irrevocably harm blood vessels in the short and long term, subsequently leading to increased aortic/arterial stiffness and arteriosclerosis. "Since central aortic pressures and arterial stiffness are much better predictors for future cardiovascular events than peripheral pressures we focused the present study on the effects of RDN on central hemodynamics and arterial stiffness," said Mr Franzen.
The researchers studied 21 patients with therapy resistant hypertension (61.9% men; mean age 64 years; 5.0±1.3 antihypertensive drugs) and 6 controls (83.3% men; mean age 57 years; 4.3±2.3 antihypertensive drugs). The inclusion criteria were: (i) use of >3 antihypertensive drugs, (ii) peripheral blood pressure at baseline ≥150 mmHg, and (iii) exclusion of secondary hypertension and anatomical abnormalities of the renal arteries.
RDN was performed with an RDN radiofrequency ablation catheter system (1). Central hemodynamics and arterial stiffness, i.e. pulse wave velocity (PWV), were recorded with an Arteriograph device (2). Measurements were performed at baseline, and 3 and 6 months after the intervention.
RDN led to an improvement in all parameters compared to baseline. Peripheral systolic blood pressure improved by 7.6% (145 mmHg versus 156 mmHg, p<0.05) after 3 months and by 5.4% (148 mmHg versus 156 mmHg, p<0.05) after 6 months. Central systolic blood pressure improved by 9.5% (147 mmHg versus 161 mmHg, p<0.01) after 3 months and by 6.6% (151 mmHg versus 161 mmHg, p<0.05) after 6 months. Most importantly, PWV improved significantly, both at 3 months (9.4±1.2 m/s versus 10.9±1.8 m/s, p<0.01) and 6 months (9.7±1.8 m/s versus 10.9±1.8 m/s, p<0.01). Univariate analysis of variance (f-test) showed that the improvement of PWV was, at least in part, blood pressure independent.
In controls no significant changes in blood pressure values or PWV were observed.
"Besides peripheral blood pressures, RDN improved central blood pressures and arterial stiffness, i.e. PWV," said Mr Franzen. "According to age adjusted reference values, the improvement of approximately 1m/s PWV observed in our study could be interpreted as a blood vessel rejuvenation of almost 10 years. This suggests that RDN might be a fountain of youth for blood vessels in patients with therapy resistant hypertension."

Abstract
BACKGROUND:
Arterial stiffness parameters are commonly used to determine the development of atherosclerotic disease. The independent predictive value of aortic stiffness has been demonstrated for coronary events.
HYPOTHESIS:
The aim of our study was to compare regional and local arterial functional parameters measured by 2 different noninvasive methods in patients with verified coronary artery disease (CAD). We also compared and contrasted these stiffness parameters to the coronary SYNTAX score in patients who had undergone coronary angiography.
METHODS:
In this study, 125 CAD patients were involved, and similar noninvasive measurements were performed on 125 healthy subjects. The regional velocity of the aortic pulse wave (PWVao) was measured by a novel oscillometric device, and the common carotid artery was studied by a Doppler echo-tracking system to determine the local carotid pulse wave velocity (PWVcar). The augmentation index (AIx), which varies proportionately with the resistance of the small arteries, was recorded simultaneously.
RESULTS:
In the CAD group, the PWVao and aortic augmentation index (Alxao) values increased significantly (10.1 ± 2.3 m/sec and 34.2% ± 14.6%) compared to the control group (9.6 ± 1.5 m/sec and 30.9% ± 12%; P < 0.05). We observed similar significant increases in the local stiffness parameters (PWVcar and carotid augmentation index [Alxcar]) in patients with verified CAD. Further, we found a strong correlation for PWV and AIx values that were measured with the Arteriograph and those obtained using the echo-tracking method (r = 0.57, P < 0.001 for PWV; and r = 0.65, P < 0.001 for AIx values).
CONCLUSIONS:
