Background. Arterial stiffness is associated with an increased risk of cardiovascular disease (CVD) and carotid-femoral pulse wave velocity (cfPWV) is considered as the ‘gold standard’ measurement method. However cfPWV does not assess the stiffness of the proximal aorta and its sensitivity at higher...

Background: The Valsalva manoeuvre (VM) is a physiological manoeuvre capable of generating profound changes in venous return. Although its physiology has been extensively described, the predominant focus has been on dynamic effects on cardiac preload with subsequent impact on cardiac output. However,...

Arterial stiffness (AS) is generally measured by regional arterial pulse wave velocity (rPWV) or locally by arterial distensibility. Although often used interchangeably, some studies show a weak correlation between these well accepted AS index depending on population. Thus, we aim to investigate in an...

The use of social media as a marketing tool has been predominantly apparent in the last few years. For marketers, social media is seen as an opportunity to advertise their product or services. Thereby, it is expected that social media reaches far more users than traditional media and eventually converts...

Background: Aortic elasticity properties (aortic distensibility, compliance, elastic modulus, and stiffness index) can be evaluated by cross-sectional thoracic aorta areas measurements at 2 times of the cardiac cycle (peak systolic and end-diastolic phases) with PC-cine MRI series. Pulse wave velocity...

Background. Evidence-based thresholds for risk stratification based on pulse pressure (PP) are currently unavailable. Methods. To derive outcome-driven thresholds for the 24-h ambulatory PP, we analyzed 9938 people randomly recruited from 11 populations (47.3% women). After age stratification (<60...
