1. Retinal vascular calibers in contemporary patients with chronic systemic inflammatory diseases: The Greek REtinal Microcirculation (GREM) study

Evaggelia K. Aissopou, Athanase D. Protogerou, Theodore G. Papaioannou, Maria Tektonidou, Nikolaos Tentolouris, Panagiotis G. Theodossiadis, Coen D.A. Stehouwer, George D. Kitas, Petros P. Sfikakis
Pages: 1 - 6
Background: Chronic systemic inflammatory diseases (CSID) are associated with increased cardiovascular morbidity and mortality. Widening of retinal venular calibers has been independently associated with systemic inflammation and cardiovascular risk in the general population. We aimed to test the hypothesis...

2. Differences in photoplethysmography morphological features and feature time series between two opposite emotions: Happiness and sadness

Fei Li, Licai Yang, Hongyu Shi, Chengyu Liu
Pages: 7 - 13
It has been well established that change in emotion state is associated with the change in physiological signals. This paper aimed to investigate the differences of finger photoplethysmography (PPG) morphological features and feature time series between happiness and sadness emotion states. Fifty-three...

3. Viscoelastic mechanical measurement of the healthy and atherosclerotic human coronary arteries using DIC technique

Alireza Karimi, Ahmad Shojaei, Reza Razaghi
Pages: 14 - 21
Purpose: Atherosclerotic is a specific form of vascular disease showed to be in charge of the 30% of mortalities in the United States alone. Many studies so far have been reported on the linear and nonlinear mechanical properties of the human and animal coronary arteries. However, the Quasilinear Viscoelastic...

4. Noninvasive evaluation of varying pulse pressures in vivo using brachial sphymomanometry, applanation tonometry, and Pulse Wave Ultrasound Manometry

Ronny X. Li, Ada Ip, Elena Sanz-Miralles, Elisa E. Konofagou
Pages: 22 - 28
The routine assessment and monitoring of hypertension may benefit from the evaluation of arterial pulse pressure (PP) at more central locations (e.g. the aorta) rather solely at the brachial artery. Pulse Wave Ultrasound Manometry (PWUM) was previously developed by our group to provide direct, noninvasive...

5. Estimation of maximal oxygen consumption and heart rate recovery using the Tecumseh sub-maximal step test and their relationship to cardiovascular risk factors

Alun D. Hughes, Nish Chaturvedi
Pages: 29 - 35
Background: Maximum aerobic capacity (VO2max) is associated with lower cardiovascular and total mortality. Step tests can be used to provide an estimate of (VO2max) in epidemiological or home-based studies. We compared different methods of estimation of VO2max and heart rate recovery and evaluated the...

6. Endothelin 1 and endothelial dysfunction in children with idiopathic nephrotic syndrome

Venkatesh Arumugam, Abhijeet Saha, Manpreet Kaur, Kanika Kapoor, Nimisha Arora, Trayambak Basak, Shantanu Sengupta, Ajay Bhatt, Nitin Bharadwaj, Vineeta V. Batra, Ashish Datt Upadhyay
Pages: 36 - 40
Background: Endothelial dysfunction is the initial step for atherogenesis. Children with idiopathic nephrotic syndrome are at risk of endothelial dysfunction due to altered cholesterol metabolism which can lead to early atherosclerosis. Methods: In this analytical study with longitudinal follow up 25...

7. Gut microbiota and vascular biomarkers in patients without clinical cardiovascular diseases

Daria Kashtanova, Olga Tkacheva, Anna Popenko, Lilit Egshatyan, Alexander Tyakht, Dmitry Alexeev, Yulia Kotovskaya, Ekaterina Plokhova, Sergey Boytsov
Pages: 41 - 48
The aim of this research was to study the association between the gut microbiota composition and arterial wall properties. The study included 92 participants, men and women aged 25–76 years old without clinical manifestation of chronic diseases but with the possible presence of cardiovascular risk factors....

8. Practical solutions for hypertensive patients with dyslipidemia☆

Charalambos Vlachopoulos, Nikolaos Ioakeimidis
Pages: 49 - 54
Arterial hypertension and dyslipidemia often coexist and constitute major risk factors of ischemic heart disease. Aggressive treatment of both comorbidities is of paramount importance to decrease global risk. Low adherence is a determinant of poor risk factor control and increases adverse cardiovascular...

9. Wave potential: A unified model of arterial waves, reservoir phenomena and their interaction☆

Jonathan P. Mynard, Joseph J. Smolich
Pages: 55 - 63
Models of haemodynamics play a central role in current research directed to understanding and addressing cardiovascular disease. Although conventional windkessel and wave models are very useful, they are incompatible due to conflicting assumptions and neither comprehensively explain the basis and interdependencies...

11. Should a statin be given to all hypertensive patients?

Harry Struijker-Boudier
Pages: 66 - 68
Statins have become an essential treatment for primary and secondary prevention of cardiovascular risk. This has been firmly established for patients with a relatively high risk for cardiovascular complications. Recent studies, in particular the HOPE trial, has extended this observation to patients with...

14. Towards a consensus on the understanding and analysis of the pulse waveform: Results from the 2016 Workshop on Arterial Hemodynamics: Past, present and future

Patrick Segers, Michael F. O’Rourke, Kim Parker, Nico Westerhof, Alun Hughes,
Pages: 75 - 80
This paper aims to summarize and map contemporary views on some contentious aspects of arterial hemodynamics that have remained unresolved despite years of research. These were discussed during a workshop entitled Arterial hemodynamics: past, present and future held in London on June 14 and 15, 2016....

15. Application of arterial hemodynamics to clinical practice: A testament to medical science in London

Michael F. O’Rourke, Audrey Adji, Wilmer W. Nichols, Charalambos Vlachopoulos, Elazer R. Edelman
Pages: 81 - 86
A strong heritage of science has been handed down in Britain from outstanding individuals, promoted and encouraged by strong scientific and medical societies. Application to clinical practice in recent years has been slow but can be expected to advance in the present and future age of new sensors, fast...

16. The reservoir-wave model☆

Kim H. Parker
Pages: 87 - 101
This paper is based on a talk given at the Arterial Hemodynamics: Past, Present and Future symposium in June 2016. Like the talk it is divided into three different but related parts. Part 1 describes the calculation of reservoir and excess pressure from clinical pressure waveforms measured at 5 different...

17. Waves and Windkessels reviewed

Nicolaas Westerhof, Berend E. Westerhof
Pages: 102 - 111
Pressure and flow are travelling waves and are reflected at many locations. The forward and reflected waves, obtained by wave separation, are compound waves. This compounded character of the reflected wave explains why its magnitude decreases with increased peripheral resistance, why it appears to run...
