169. 4.2 THE INHOMOGENEITY OF DIASTOLIC-SYSTOLIC RISE TIME OF THE DISTENSION WAVEFORM DISTRIBUTION IN THE COMMON CAROTID ARTERY IS ASSOCIATED WITH LIPID PRESENCE OF DISTAL PLAQUES
J. Steinbuch*, F.H.B.M. Schreuder, M.T.B. Truijman, A.A.J. de Rotte, M.I. Liem, E. Hermeling, A.P.G. Hoeks, W.H. Mess
Pages: 44 - 44
Objectives: Diastolic-systolic rise time characteristics of the distension waveform distribution, i.e., mean and inhomogeneity, might be modified by wave reflections from distal plaques. The aim of this study is to investigate the association between rise time characteristics for the common carotid artery...

170. 4.3 THE EFFECT OF GLYCAEMIC STATE TRANSITION ON ACCELERATED AORTIC STIFFENING: A LONGITUDINAL STUDY IN THE WHITEHALL II COHORT
Nanna B. Johansen*, Martin Shipley, Daniel R. Witte, Adam G. Tabak, Eric J. Brunner
Pages: 44 - 44
In 4,759 participants from the Whitehall II study, we examined the impact of glycaemic history on aortic stiffening. Assessment of aortic stiffness by carotid-femoral pulse wave velocity (PWV) was performed twice with a 4 year interval (2007–2009 and 2012–2013). At the first aortic stiffness assessment...

171. 4.4 FORWARD AND BACKWARD WAVES AT THE AORTIC ROOT: STEADY-STATE AND WAVE RE-REFLECTION CONSIDERATIONS
Timothy Phan*, John Li, Vandan Panchal, Amer Syed, Ejaz Shah, Julio Chirinos
Pages: 44 - 45
Background: The assumption of steady-state oscillation is often overlooked when arterial pressure and flow waveforms are decomposed into backward (Pb) and forward waves (Pf). This has led to various misinterpretations including a significant reflection-free time during early-systole and attribution of...
Conference Abstract
172. 4.5 A SYSTEMATIC REVIEW AND META-ANALYSIS OF CENTRAL TO BRACHIAL BLOOD PRESSURE AMPLIFICATION IN PATIENTS TYPE 2 DIABETES MELLITUS
Rachel Climie*, Petr Otahal, Martin Schultz, James Fell, Velandai Srikanth, James Sharman
Pages: 45 - 45
Background: Brachial blood pressure (BP) may not reflect central BP due to systolic BP (SBP) amplification. Patients with type 2 diabetes mellitus (T2DM) elicit vascular irregularities that may affect SBP amplification or other central BP indices (including pulse pressure [PP], augmentation pressure...
Conference Abstract
173. 4.6 RELATIONSHIP OF CAROTID ARTERIAL FUNCTIONAL AND STRUCTURAL CHANGES TO LEFT ATRIAL VOLUME INUNTREATED HYPERTENSION
Joanna Jaroch*, Barbara Rzyczkowska, Zbigniew Bociaga, Olga Vriz, Caterina Driussi, Maria Loboz-Rudnicka, Krzysztof Dudek, Krystyna Loboz-Grudzien
Pages: 45 - 45
The contribution of arterial functional and structural changes to left ventricular (LV) diastolic dysfunction has been the area of latest research. There are some studies on the relationship of arterial stiffness (a.s.) and left atrial (LA) remodeling as a marker of diastolic burden. Little is known...
Conference Abstract
174. 5.1 INERTIAL-VISCOELASTIC MINIMAL MODEL OF THE ARTERIAL SYSTEM RECONCILES ARTERIAL COMPLIANCE ESTIMATIONS
Timothy Phan*, John Li, Maheshwara Koppula, Izzah Vasim, Swapna Varakantam, Julio Chirinos
Pages: 45 - 45
Background: The arterial system is viscoelastic rather than purely elastic. There exist various methods to characterize the purely elastic nature of arterial compliance, each method yielding different values. The pulse pressure method (CPPM), estimating compliance by matching the pulse pressure (PP)...
Conference Abstract
175. 5.2 SOLUBLE RECEPTOR FOR ADVANCED GLYCATION END-PRODUCTS AND AORTIC STIFFNESS IN GENERAL POPULATION
Otto Mayer, Jan Filipovsky*, Jitka Seidlerova, Petra Karnosova, Peter Wohlfahrt, Renata Cifkova, Jindra Windrichova, Ondrej Topolcan
Pages: 45 - 46
It has been suggested that accumulation of advanced glycation end-products (AGE) is involved in several pathophysiological processes in the vessel wall. Soluble isoform of receptor for AGE (sRAGE) acts as a decoy for capturing circulating AGE, prevents them from binding to the cell-surface receptor and...
Conference Abstract
176. 5.3 THE INFLUENCE OF SEX AND AGE ON ARTERIAL FUNCTION IN RESPONSE TO AN ACUTE INFLAMMATORY STIMULUS
Alexander Rosenberg*, Abbi Lane-Cordova, Kanokwan Bunsawat, Sang Ouk Wee, Tracy Baynard, Bo Fernhall
Pages: 46 - 46
Background: Aging is associated with increased arterial stiffness and chronic low-grade inflammation. Acute inflammatory stimulus in the presence of low-grade chronic inflammation briefly increases the risk of cardiovascular events. The risk of cardiovascular events also increases substantially in older...

177. 5.4 MATRIX GLA PROTEIN IN RELATION TO LEFT VENTRICULAR DIASTOLIC FUNCTION
Thibault Petit*, Zhen-Yu Zhang, Wen-Yi Yang, Fang-Fei Wei, Yu-Mei Gu, Juditha Knez, Nicholas Cauwenberghs, Yan-Ping Liu, Nadja Drummen, Lotte Jacobs, Lutgarde Thijs, Tatiana Kuznetsova, Stefan Janssens, Cees Vermeer, Jan A. Staessen
Pages: 46 - 46
Introduction: Matrix Gla Protein (MGP) is highly expressed in cardiomyocytes and is upregulated after acute and chronic pressure overload and in myocardial hypertrophy in mice and humans. However, no study addressed the relation between cardiac function and MGP in humans.
Methods and results: In 767...
Conference Abstract
178. 5.5 MEASUREMENT OF ARTERIAL STIFFNESS BY ULTRAFAST ECHO: COMPARISON WITH ECHOTRACKING IN NORMOTENSIVE SUBJECTS AND HYPERTENSIVE PATIENTS
Louise Marais*, Mathieu Pernot, Hakim Khettab, Mickael Tanter, Emmanuel Messas, Mustapha Zidi, Stéphane Laurent, Pierre Boutouyrie
Pages: 46 - 46
Because measurement of arterial stiffness is highly dependent on blood pressure (BP), methods independent of BP are required. Ultrafast echography (UFE, Supersonic Imagine, Aix en Provence, France) makes use of very fast sampling rate (up to 10 kHz), so transient events such as pressure wave arrival...
Conference Abstract
179. 5.6 ASSOCIATION BETWEEN ENDOGENOUS SERUM TESTOSTERONE CONCENTRATIONS AND AORTIC PRESSURES AND PULSE WAVE AMPLIFICATION INDICES IN ERECTILE DYSFUNCTION PATIENTS
Dimitrios Terentes-Printzios*, Charalambos Vlachopoulos, Nikolaos Ioakeimidis, Panagiota Pietri, Athanassios Angelis, Ioanna Gourgouli, Christos Georgakopoulos, Christodoulos Stefanadis, Dimitrios Tousoulis
Pages: 46 - 47
Purpose: Erectile dysfunction (ED) is an independent predictor of future cardiovascular (CV) events. Aortic pressures (central) and low testosterone independently predict future CV events and mortality. The relationship between testosterone, central pressures and wave reflection indices in ED patients...

180. Design and progress of a factorial trial testing the effect of spironolactone and inorganic nitrate on arterial function in people at risk of or with type 2 diabetes
Charlotte E. Mills, Virginia Govoni, Maria Linda Casagrande, Luca Faconti, Andrew J. Webb, J. Kennedy Cruickshank
Pages: 48 - 53
Background: Arterial stiffness (AS), as pulse wave velocity (PWV), is a powerful independent predictor of cardiovascular events and commonly complicates type 2 diabetes (T2D). This trial aims to test if AS, measured by the VaSera machine as cardio-ankle vascular index (CAVI) and by Arteriograph measuring...

181. Regional differences in the vascular response to CO2 among cerebral, ocular, and mesenteric vessels
A. Miyaji, T. Ikemura, Y. Hamada, N. Hayashi
Pages: 54 - 59
Background: It is well-known that cerebral and ocular vessels are highly sensitive to changes in the partial pressure of CO2 (PETCO2). However, it is unclear whether there are regional differences in the magnitude of the vascular response to CO2 (CO2 reactivity) in various vessels of a single individual,...
