Gordons Chemists Launch a new Cardiovascular Screening Clinic
23 May 2014 12:19:30

CardioHealth NI – Give your arteries an MOT!

Gordons Chemists are pleased to offer a new cardiovascular screening clinic.
Statistics indicate that around 60% of the time in heart attack cases, a standard cholesterol or blood pressure test won’t have revealed anything out of the ordinary. Guidelines (published in 2007) from the European Society of Hypertension recommend measuring arterial stiffness in patients with arterial hypertension (high blood pressure).
Gordons Chemists are pleased to offer across Northern Ireland a cardiovascular screening clinic, using a state-of-the-art arteriograph. CardioHealth NI is the first and only company in Northern Ireland that uses an arteriograph; a session with CardioHealth NI at one of our cardiovascular screening clinics is priced at only £50.
A cardiovascular screening using an arteriograph reveals much more than a typical blood pressure or cholesterol test will. By offering this cardiovascular screening clinic, we allow the patient to have a better understanding of the health of their arteries. As such they can make the decision to take control of their cardiovascular health – hopefully reducing the incidence or severity of heart attack, stroke or high blood pressure.
In addition to identifying underlying health problems, the screening includes recommendations on diet and natural health solutions. A detailed report allows the patient to consult with their GP or medical professional in order to seek further advice and treatment, based on the findings of the screening.
The cardiovascular screening clinic is suitable for anyone aged 16 years and over, or anyone with a family history of heart disease, kidney disease or diabetes. It’s also suitable for anyone who drinks alcohol or smokes, is overweight, or participates in (or is returning to) a sport.

About the Arteriograph
An arteriograph is a sophisticated instrument used for detecting changes to the artery walls. The arteriograph uses a cuff that contains special pressure sensors.
These pressure sensors are designed to detect the Pulse Wave (pressure wave) that leaves the heart as it contracts. When the pulse wave reaches the end of the arterial system, it is then reflected back towards the heart. Three key measurements are taken from this pulse wave.
An arteriograph reveals damage to the heart and arteries that a standard blood pressure or cholesterol test will not. It measures parameters that indicate if the patient might at risk of heart attack or stroke, including:
Central Systolic Blood Pressure
This in effect measures blood pressure, at the heart. Studies indicate that this is of greater value than measuring blood pressure on the arm.
Brachial Augmentation
This reveals early damage to, and clogging up of, your smaller arteries. When arterial clogging begins, it occurs firstly in the small arteries of the hands and feet. This can be measured and it indicates the degree of clogging and the damage to the inner lining of your smaller arteries.
Pulse Wave Velocity
The speed of the pressure wave described above is measured over a given distance. An increased speed indicates a clogging of the arteries. There is a direct correlation between this, and an increased risk of heart attack/stroke. The reading is often found to be abnormal in patients with kidney disease, diabetes, sufferers of rheumatoid arthritis, and smokers.
The Arteriograph is a new, easy-to-use, and time-effective method for assessing arterial stiffness. Prior to the arteriograph, there were (and still are) two invasive methods used within a hospital setting: the tonometric and piezo-electronic systems (SphygmoCor and Complior).
An arteriograph is not intended as a replacement for these. Instead, the device is intended for use as a quick, affordable and non-invasive means of diagnosing an underlying condition that the patient may not be aware of. Clinical trials (see below for details) reveal that an arteriograph gives accurate results (which are comparable to the two systems mentioned).
The main advantage of using an arteriograph is that it offers a quick and affordable assessment, using only the upper arm.
Other methods involve a detailed examination and take time to complete. Typically, these (due to the time and expense involved in completing a screening) aren’t readily available at the request of a patient.
CardioHealth NI’s cardiovascular screening clinics offer the patient the opportunity to have a detailed and accurate assessment of their cardiovascular system completed – at a relatively low price, in a location close to them, in just half an hour.
Upcoming clinic detail can be obtained by emailing: info@gordonsdirect.com

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

Arterial Stiffness

Comparison of aortic pulse wave velocity measured by three
techniques: Complior, SphygmoCor and Arteriograph

Background New 2007 European Society of Hypertension
guidelines recommend measuring arterial stiffness in
patients with arterial hypertension, suggesting a
carotid–femoral pulse wave velocity over 12 m/s as an
estimate of subclinical organ damage. Considering this
cutoff point, it is worth exploring whether or not there are
significant differences in results obtained using various
techniques for measuring aortic pulse wave velocity. The
aim of the study was to compare aortic pulse wave velocity
measurements using Complior, SphygmoCor, and
Arteriograph devices, and to assess the effect of pulse wave
transit time and traveled distance on pulse wave velocity
values.
Methods Aortic pulse wave velocity was measured on a
single visit, using these devices, in randomized order, in a
group of 64 patients with grade 1 or 2 arterial hypertension.
Results Aortic pulse wave velocity measured using
Complior (10.1W1.7 m/s) was significantly higher than that
obtained using SphygmoCor (8.1W1.1 m/s) or Arteriograph
(8.6W1.3 m/s). No differences were noted between pulse
wave velocity measurements using SphygmoCor and
Arteriograph. Between-method comparison revealed that
differences in traveled distance were significant: Complior

and tonometric (SphygmoCor) techniquesM

Background Arterial stiffness, measured as aortic
pulse wave velocity (PWV), and wave reflection,
measured as augmentation index (AIx), are independent
predictors for total and cardiovascular morbidity and
mortality. The aim of this study was to compare a new
device, based on oscillometric pressure curves
(Arteriograph), which simultaneously measures PWV and
AIx, with standard techniques for measuring PWV
(Complior) and AIx (SphygmoCor) in untreated
hypertensive patients.
Methods We compared PWV and AIx measured using the
Arteriograph with corresponding Complior and
SphygmoCor measurements in 254 untreated hypertensive
patients, age 48W14 years (meanWSD, range 17–85
years).
Results Arteriograph PWV and AIx were closely related with
Complior (rU0.60, P<0.001) and SphygmoCor (rU0.89,
P<0.001), respectively. Using stepwise regression analysis,
the independent determinants of Arteriograph PWV were
age, mean arterial pressure, heart rate and sex (r2U0.44,
P<0.0001) and for AIx were age, weight, mean arterial
pressure, heart rate and sex (r2U0.65, P<0.0001). The bias
between the different techniques was determined by age
and sex for PWV and age, body weight, sex, heart rate and

Introduction
Following the 2006 expert consensus document of the
European Network for Noninvasive Investigation of
Large Arteries [1], arterial stiffness and central pressure
measurements should be considered as recommended
tests for the evaluation of cardiovascular risk, particularly
in patients in whom target organ damage is
not discovered by routine investigations. Within the
area of noninvasive methods, pulse wave recording
and analysis either from central (ascending aorta, carotid
artery) or peripheral (radial artery) sites have become
popular, particularly after the release of dedicated commercial
devices [2]. Theoretically, pulse wave analysis

Precise assessment of cardiovascular risk factors is a
necessary step for the identification of patients at high
risk of developing cardiovascular events. When setting
the operating curve of the risk function, measurement of
blood glucose and lipids, estimation of blood pressure
(BP) levels, identification of smoking status, and assessment
of existing organ damage represent the main determinants
of the tendency to develop cardiac and vascular
problems over and above the impact of nonmodifiable
factors such as age and sex. Each of these classical risk
factors is included in a risk function specific to a given
population and aimed at yielding absolute quantitative
values of cardiovascular risk [1,2]. Such an approach

Arterial Stiffness

Assessment of arterial stiffness in hypertension: comparison of oscillometric (Arteriograph), piezoelectronic (Complior) and tonometric (SphygmoCor) techniques.
Abstract
BACKGROUND
Arterial stiffness, measured as aortic pulse wave velocity (PWV), and wave reflection, measured as augmentation index (AIx), are independent predictors for total and cardiovascular morbidity and mortality. The aim of this study was to compare a new device, based on oscillometric pressure curves (Arteriograph), which simultaneously measures PWV and AIx, with standard techniques for measuring PWV (Complior) and AIx (SphygmoCor) in untreated hypertensive patients.
METHODS
We compared PWV and AIx measured using the Arteriograph with corresponding Complior and SphygmoCor measurements in 254 untreated hypertensive patients, age 48 +/- 14 years (mean +/- SD, range 17-85 years).
RESULTS
Arteriograph PWV and AIx were closely related with Complior (r = 0.60, P < 0.001) and SphygmoCor (r = 0.89, P < 0.001), respectively. Using stepwise regression analysis, the independent determinants of Arteriograph PWV were age, mean arterial pressure, heart rate and sex (r(2) = 0.44, P < 0.0001) and for AIx were age, weight, mean arterial pressure, heart rate and sex (r(2) = 0.65, P < 0.0001). The bias between the different techniques was determined by age and sex for PWV and age, body weight, sex, heart rate and mean arterial pressure for AIx. Bland-Altman plots showed that although the techniques were closely related, the limits of agreement were wide.
CONCLUSION
Although Arteriograph values and the determinants of PWV and AIx are in close agreement with corresponding parameters obtained by Complior and SphygmoCor, respectively, the techniques are not interchangeable.
