1. Effect of angulation and Reynolds number on recirculation at the abdominal aorta-renal artery junction

Mohammed Ameenuddin, Mohan Anand
Pages: 1 - 8
We investigate the effect of renal artery angle variation and Reynolds number on the probability of formation of atherosclerosis-prone regions at the abdominal aorta-renal artery junction. The rheologically accurate shear-thinning Yeleswarapu model for blood is used to simulate flow in a 3-Dimensional...

2. A unified mechanism for the water hammer pulse and pulsus bisferiens in severe aortic regurgitation: Insights from wave intensity analysis

Julio A. Chirinos, Scott R. Akers, Jan A. Vierendeels, Patrick Segers
Pages: 9 - 12
The carotid bisferiens pulse and the radial water hammer pulse are typical of severe chronic aortic regurgitation. Little is known about the mechanism of these classic cardiovascular signs identified on physical examination. We report the first characterization of these abnormal pulse patterns using...

3. Carotid extra-media thickness increases with age, but is not related to arterial stiffness in adults

Hon Lam Choi, Jason S. Au, Maureen J. MacDonald
Pages: 13 - 19
Background: Assessment of carotid artery perivascular adipose tissue through carotid artery extra-media thickness (EMT) ultrasonography has emerged as a novel assessment technique that might contribute unique information to comprehensive evaluations of arterial health. Currently, there is a lack of research...

4. IL-17 producing CD4+CD45RO+ T-cells in atherosclerosis express GITR molecule

Atefe Ghamar Talepoor, Negar Behnamfar, Mohammad Javad Zibaeenezhad, Mehrnoosh Doroudchi
Pages: 20 - 28
Background: Atherosclerosis (AS) is a chronic inflammatory disease of vessel walls associated with infiltration of immune cells which their function is controlled by different co-stimulatory and co-inhibitory receptors. We investigated the expression of co-inhibitory molecules on the memory and effector...

5. Flow-mediated slowing of brachial-radial pulse wave velocity: Methodological aspects and clinical determinants

Nicholas Cauwenberghs, Yenthel Heyrman, Lutgarde Thijs, Wen-Yi Yang, Fang-Fei Wei, Zhen-Yu Zhang, Jan A. Staessen, Tatiana Kuznetsova
Pages: 29 - 37
Background: Recent studies proposed that deceleration in pulse wave velocity (PWV) following reactive hyperaemia might reflect arterial distensibility and endothelial function. We therefore investigated methodological aspects and clinical determinants of new indexes of flow-mediated slowing (FMS) of...

6. Vasoreactivity of thoracic aorta in Nigella Sativa supplemented and/or exercise trained rats

Rabia Latif, Al-Asoom LI
Pages: 38 - 42
Background: Nigella Sativa (NS) induced vasorelaxation of aortic rings upon direct exposure has been documented in literature. This study was conducted to determine whether 8 weeks Nigella Sativa supplementation and/or exercise training may alter vascular sensitivity of rat aorta in normal, healthy rats. Methods:...

7. Elevated levels of IL-6 and IL-9 in the sera of patients with AAA do not correspond to their production by peripheral blood mononuclear cells

Hamid Aria, Mehdi Kalani, Hossein Hodjati, Mehrnoosh Doroudchi
Pages: 43 - 52
Background: Abdominal Aortic Aneurysm (AAA) is the stable local dilatation of abdominal aorta. AAA is an inflammatory condition in which cytokines may play a pathogenic role. Methods: Peripheral Blood Mononuclear cells (PBMCs) were isolated from 5 men, with confirmed diagnosis of AAA and aortic dilation...

8. Impact of leg heating on central hemodynamics in postmenopausal women

Keisei Kosaki, Jun Sugawara, Asako Zempo-Miyaki, Seiji Maeda
Pages: 53 - 57
Background: The determinants responsible for increasing central pressure augmentation, a strong risk factor for cardiovascular disease, remain highly controversial. The aim of this study was to determine the contribution of the impedance mismatch between central and leg arteries on central pressure augmentation....
Review Article

9. The clinical importance of exercise blood pressure

Martin G. Schultz
Pages: 58 - 62
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. Whilst systolic BP should normally rise with incremental exercise, and diastolic BP remains relatively stable,...

10. Stiff vessels approached in a flexible way: Advancing quantification and interpretation of arterial stiffness☆

Bart Spronck
Pages: 63 - 68
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 behaves stiffer or less stiff does not...

11. Fetal programming and vascular dysfunction

T.A. Meister, E. Rexhaj, S.F. Rimoldi, U. Scherrer, C. Sartori
Pages: 69 - 77
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...
