INTRODUCTION: Enhanced External Counter Pulsation (EECP) is a non-invasive treatment option for patients with Coronary Artery Disease (CAD). The treatment has shown to augment diastolic pressure and reduce Left Ventricular (LV) after-load by reducing systemic vascular resistance. The effect of EECP in standard brachial blood pressure and central haemodynamic parameters are not known. AIM: We hypothesized that EECP may have differential effect in CAD patients with low systolic blood pressure when compared to normal systolic pressure and the mechanism underlying this differential effect may be due to improvement in LV function...

INTRODUCTION: Increased blood pressure (BP) variability is a cardiovascular risk marker for young individuals and may relate to the ability of their aorta to buffer cardiac output. We used a multimodality approach to determine relations between central and peripheral arterial stiffness and BP variability. METHODS: We studied 152 adults (mean age of 31 years) who had BP variability measures based on SD of awake ambulatory BPs, 24-h weighted SD and average real variability (ARV)...

BACKGROUND AND OBJECTIVES: Large-artery stiffness is an independent predictor of cardiovascular disease (CVD), and carotid-femoral pulse wave velocity (cfPWV) is considered the gold standard measure of arterial stiffness. A resting heart rate is an easily measured vital sign that is also associated with CVD morbidity and mortality. Previous studies have reported the significant relationship of a resting heart rate with arterial stiffness as measured by cfPWV only in hypertensive subjects; their relationship in nonhypertensive subjects remains unknown...

OBJECTIVES: Many reports exist of the cardiovascular toxicity of smoked cannabis but none of arterial stiffness measures or vascular age (VA). In view of its diverse toxicology, the possibility that cannabis-exposed patients may be ageing more quickly requires investigation. DESIGN: Cross-sectional and longitudinal, observational. Prospective. SETTING: Single primary care addiction clinic in Brisbane, Australia. PARTICIPANTS: 11 cannabis-only smokers, 504 tobacco-only smokers, 114 tobacco and cannabis smokers and 534 non-smokers...

BACKGROUND: Studies have established the prognostic value of central SBP and pulse pressure (PP). The SphygmoCor XCEL (AtCor Medical, Sydney, Australia) device provides practical central blood pressure (BP) measurement for daily clinical use with its easy-to-use, operator-independent procedure. However, this device has not been validated against invasive measurement. METHOD: Simultaneous oscillometric and high-fidelity invasive measurements of central SBP and PP were compared for 36 patients who underwent coronary arteriography...

Although microvascular disease is a hallmark of systemic sclerosis (SSc), a higher prevalence of macrovascular disease and a poorer related prognosis have been reported in SSc than in the general population. The simultaneous assessment of prognostically relevant functional properties of larger and smaller arteries, and their effects on central hemodynamics, has never been performed in SSc using the state-of-the-art techniques. Thirty-four women with SSc (aged 61±15 years, disease duration 17±12 years, and blood pressure 123/70±18/11 mm Hg) and 34 healthy women individually matched by age and mean arterial pressure underwent the determination of carotid-femoral (aortic) and carotid-radial (upper limb) pulse wave velocity (a direct measure of arterial stiffness), aortic augmentation (a measure of the contribution of reflected wave to central pulse pressure), and aortobrachial pulse pressure amplification (brachial/aortic pulse pressure) through applanation tonometry (SphygmoCor)...

OBJECTIVE: To assess the feasibility of measuring non-invasively central aortic blood pressure (BP) and indices of arterial stiffness (aortic augmentation index (AIx) and pulse wave velocity (PWV)) in 3-5 year old children and assess if vascular function is affected by vascular inflammation (Serum C-reactive protein (CRP)) and /or cortisol. DESIGN AND METHOD: Central BP, AIx, and PWV were measured using applanation tonometry (SphygmoCor) in 16 children recruited from Head Start centers in AL...

OBJECTIVE: Central blood pressure (BP) is reported to associate with target organ damages (TODs) better than brachial BP. However, data regarding the association of TODs with central and brachial BP in the community-dwelling health elderly are scare. We therefore hypothesized that TODs are better associated with central than brachial blood pressure (BP) in the elderly community-based population, with considering all hypertensive TODs, namely left ventricular hypertrophy (LVH), left ventricular (LV) diastolic dysfunction (DD), carotid plaque, arteriosclerosis and microalbuminuria...

OBJECTIVE: Previous studies have shown the reciprocal effects of wave reflection on aortic pressure and aortic flow waves. Invasive (Electro-Magnetic (EM)) and non-invasive (Cardiac Magnetic Resonance (CMR)) studies of aortic blood flow have shown characteristic aging changes as reduction in late systolic flow, which corresponds in time to the late systolic boost of aortic pressure. These are not always apparent in Doppler flow tracings. DESIGN AND METHOD: This study aimed to better understand the mechanisms of aortic pressure and flow changes due to early wave reflection and stiffening of arteries...

OBJECTIVE: Relative ease of estimating of Ascending Aortic (AA) pressure non-invasively enables interpretation of age-related pressure waveform changes due to altered pulse wave propagation. AA flow velocity waveforms, measured invasively by ElectroMagnetic (EM) cuff/ catheter, and non-invasively by Cardiac Magnetic Resonance (CMR) also show characteristic aging changes attributable to aortic dilation and subtle impairment of Left Ventricular (LV) function. Conventional Doppler waveforms do not...

OBJECTIVE: Central blood pressure (BP) is suggested to be more closely correlated to target organ damage and cardiovascular events than brachial BP. Outcome-based thresholds for the diagnosis of central hypertension has been recently proposed. However, little is known about central hypertension. In an untreated patient cohort, we therefore investigated the prevalence of central hypertension and its association with target organ damage. DESIGN AND METHOD: Consecutive untreated patients referred for ambulatory BP monitoring to our Hypertension Clinic were recruited...

OBJECTIVE: Accumulation of advanced glycation end-products (AGE) has been suggested to be involved in several pathophysiological processes in the vessel wall. Soluble isoform of receptor for AGE (sRAGE) acts as a decoy for capturing circulating AGE, thus preventing them from binding to the cell-surface receptor (RAGE) and protecting against the RAGE-AGE axis-elicited processes. We hypothesized that low sRAGE levels might be associated with increased arterial stiffness. DESIGN AND METHOD: In a cross-sectional design, we analyzed 1077 subjects, aged 25 to 64 years, from the Czech population-based study ("Post-MONICA")...

OBJECTIVE: Inter-arm systolic blood pressure (IASBP) differences ≥10 mmHg are associated with increased cardiovascular risk. Prevalence of IASBP differences is unclear given that studies are mainly in diseased populations and vary in measurement technique (sequential vs simultaneous recording). Moreover, no studies have determined whether dominant or non-dominant arm influences calculated central aortic blood pressure. The purpose of this study was to examine the prevalence of IASBP differences measured at the brachial artery and calculated at the aorta in community dwelling adults...

OBJECTIVE: Disorders of mineral metabolism predicted incidence of cardiovascular events in various clinical settings, possibly because that arterial stiffness mediate this pathway in part. We investigated the interrelationship between mineral metabolism factors and carotid-femoral PWV, and compared the effect sizes of blood pressure (BP) and mineral factors with carotid-femoral PWV in untreated Chinese. DESIGN AND METHOD: Consecutive untreated outpatients referred for ambulatory BP monitoring were recruited...

The aim of our study was to investigate the association between pulse wave velocity (PWV) and pulse wave analysis (PWA)-derived measurements for the evaluation of arterial stiffness. A total of 20 (7 male and 13 female) healthy, non-smoking individuals, with mean age 31 ± 12years were included. PWV and PWA measurements were performed using a SphygmoCor apparatus (Atcor Medical Blood Pressure Analysis System, Sydney Australia). PWV significantly correlated with all central aortic haemodynamic parameters, especially with pulse pressure (PP) (p < 0...
