Pages: 35 - 43
Brachial cuff blood pressure (BP) is clinically important, but may be an inaccurate substitute for central BP. Many non-invasive devices have been developed that purport to estimate central BP from peripheral artery sites, yet with no standardized guidelines; the accuracy testing of these new devices...

8. THE CLINICAL IMPORTANCE OF EXERCISE BLOOD PRESSURE
Martin G. Schultz
Pages: 44 - 44
Clinical exercise stress testing is a common medical test performed in cardiology and exercise physiology clinics the world over. Measurement of blood pressure (BP) during testing is mandated.

9. THE CENTRALITY OF THE HEART IN ITS RELATIONSHIP WITH THE ARTERIAL SYSTEM: WHERE IT ALL STARTS AND ENDS
Giacomo Pucci
Pages: 44 - 44
The interaction between the heart and large arteries represent a not fully understood process, which results from the integration of pressure wave generation, flow ejection, wave travel and reflection, and geometric mismatch between structures. Left ventricular (LV) mass and geometry, two independent...

10. STIFF VESSELS APPROACHED IN A FLEXIBLE WAY: ADVANCING QUANTIFICATION AND INTERPRETATION OF ARTERIAL STIFFNESS
Bart Spronck
Pages: 44 - 44
Introduction
Although pulse wave velocity (PWV), a proxy of arterial stiffness, is a strong predictor of cardiovascular complications, it is confounded by blood pressure (BP) and heart rate at the time of examination. Furthermore, establishing whether an artery is stiffened or not does not inform a...

T.A. Meister, E. Rexhaj, S.F. Rimoldi, U. Scherrer, C. Sartori*
Pages: 45 - 45
Cardiovascular diseases are the main cause of mortality and morbidity in Western countries, but the underlying mechanisms are still poorly understood. Genetic polymorphisms, once thought to represent a major determinant of cardiovascular risk, individually and collectively, only explain a tiny fraction...
Conference Abstract
12. ENDOTHELIAL AUTOPHAGY AS A KEY MECHANISM IN ARTERIAL DISEASES
Pierre-Louis Tharaux
Pages: 45 - 45
Blood flow imposes shear stress on endothelial cells (ECs). ECs are able to convert these mechanical stimuli into intracellular signals that affect cellular function. As deregulated autophagy is associated with an acceleration of a variety of cardiovascular and metabolic diseases where impaired flow-mediated...

13. VASCULAR CALCIFICATION: FROM INNOCENT BYSTANDER TO CULPRIT RISK FACTOR
Leon J. Schurgers
Pages: 45 - 45
Vascular calcification was regarded as an innocent bystander in cardiovascular disease. It was considered to be the passive chemical nucleation of calcium and phosphate ions on cellular debris and therefore the end-stage of atherosclerosis. Currently, vascular calcification is understood to be an actively...
Conference Abstract
14. TARGETING VASCULAR SMOOTH MUSCLE CELL TO IMPROVE ARTERIAL STIFFNESS
Patrick Lacolley
Pages: 45 - 45
Hypertension and arterial aging engage a plethora of key signaling pathways that act in concert to induce vascular smooth muscle cell (VSMC) phenotypic changes leading to vascular degeneration and extracellular matrix (ECM) changes responsible for alterations of the mechanical properties of the vascular...

15. CENTRAL BLOOD PRESSURE MEASUREMENT AND VALIDATION: WHAT IS STILL NEEDED?
James E. Sharman
Pages: 45 - 45
Accurate measurement of blood pressure (BP) is a critical goal for appropriate diagnosis and management of high BP. The measurement reference standard is brachial cuff BP, but recent large-scale meta-analyses show major deficiencies in the accuracy of this method. Indeed, irrespective of cuff technique...

18. CON: GLUCOSE IS THE MOST IMPORTANT TARGET FOR CARDIOVASCULAR PREVENTION IN DIABETES
Francesco Giorgino
Pages: 46 - 46
The overall impact of glucose-lowering on vascular complications and major clinical outcomes, including mortality, in type 2 diabetes is still an open issue. While intensive glucose control has undoubted benefit for microvascular endpoints, the relationship between glucose-lowering approaches and reduced...
Conference Abstract
19. THE METABOLIC-MICROVASCULAR DYSREGULATION SYNDROME
Coen D.A. Stehouwer
Pages: 46 - 46
Microvascular and metabolic physiology are inextricably linked. Thus, metabolic dysfunction impairs microvascular function and microvascular dysfunction impairs normal metabolism. The relationship is therefore reciprocal, justifying the concept of a ‘Metabolic-Microvascular Dysregulation Syndrome’. For...

20. 1.1 CENTRAL BLOOD PRESSURE, STATINS AND LDL-CHOLESTEROL: A MEDIATION ANALYSIS
Florence Lamarche, Mohsen Agharazii, Francois Madore, Remi Goupil
Pages: 47 - 47
Background: Central blood pressure (CBP) is a better predictor of cardiovascular burden than peripheral blood pressure (BP). While studies have suggested a reduction in peripheral BP with statins, it remains uncertain to what extent statins reduce CBP and whether this reduction is mediated through a...

Matthew K. Armstrong, Martin G. Schultz, Dean S. Picone, James E. Sharman
Pages: 51 - 52
Introduction: Aortic stiffness predicts cardiovascular mortality but is limited as a risk marker because it is dependent on blood pressure (BP). A potential solution is provided from the ratio of aortic-to-brachial artery stiffness (ab-ratio), which is purported to be a BP-independent risk marker among...

Pages: 54 - 55
Background and objectives: Clinical evidence shows that central (aortic) blood pressure (CBP) is a better marker of cardiovascular risk than brachial pressure [1]. However, CBP can only be accurately measured invasively, through catheterisation. We propose a novel approach to estimate CBP non-invasively...
Conference Abstract

Yao Lu, Harding Seeromanie
Pages: 57 - 57
Given the significance of lung function (LF) for vascular health in adulthood, there are surprisingly few studies that have examined the interrelationships of their developmental trajectories.
