Bilateral symmetry of brachial pulse waveform analysis in a clinical population
Background: Pulse waveforms are modified as they propagate along the arterial tree. Small differences in the arterial pathways from the heart to the left and right brachial artery may impact pulse waveform analysis (PWA) for the purpose of hemodynamic assessment. The VaSera VS-1500AU (Fukuda Denshi) is a cuff-based device that permits simultaneous acquisition of bilateral brachial pulse volume recordings. To determine if interchangeability between left and right brachial pulse waveforms is possible, we assessed whether there are significant differences in pulse waveform analysis variables between each arm.

Effect of low-dose acetylsalicylic acid on arterial stiffness in high-risk pregnancies: An observational longitudinal study
Objectives: Low-dose acetylsalicylic acid (ASA) has been shown to reduce the risk for pre-eclampsia in high-risk pregnancies when prescribed before 16 weeks of gestation. It remains unknown whether this anti-inflammatory agent has effects on arterial stiffness. Our objective was to characterize arterial stiffness indices throughout pregnancy in women with high-risk pregnancies who were and were not prescribed low-dose ASA. (Source: Artery Research)

Effect of poor glycemic control on arterial stiffness in pregnancy
Objectives: Poor glycemic control during pregnancy is associated with increased adverse perinatal outcomes. Our objective was to characterize the association between glycemic control and arterial stiffness in pregnancy. (Source: Artery Research)

Dietary calcium intake and cardiovascular health: Is there any relationship?
We examined the association of dietary calcium intake (dCa) with surrogate CV markers, including carotid intima-media thickness (cIMT), arterial stiffness and hemodynamics in healthy postmenopausal women. (Source: Artery Research)

Statin therapy in rheumatoid arthritis may improve arterial stiffness in women but not in men: A preliminary analysis
Objectives: Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. Statins have anti-inflammatory and immunomodulatory effects, thereby reducing cardiovascular risk. Arterial stiffness is a composite indicator of cardiovascular health and a predictor of cardiovascular risk. We assessed the effect of statin therapy on arterial stiffness and hemodynamics in subjects with rheumatoid arthritis. (Source: Artery Research)

First in man measurement of arterial stiffness using a connected bathroom scale: Calibration against SphygmoCor
Background: Measurement of arterial stiffness (AS) is still considered difficult. We developed a non- invasive technique to assess AS from a connected bathroom scale, based on ballistocardiography (BCG) and impedance plethysmography (IPG). (Source: Artery Research)

Effects of fixed versus auto-titrating continuous positive airway pressure on vascular function in patients with resistant hypertension and obstructive sleep apnea
Introduction: Obstructive sleep apnea (OSA) is a common cause of resistant hypertension. We investigated the effects of 2 modalities of positive airway pressure; fixed continuous airway pressure (fCPAP) versus auto-titrating positive airway pressure (APAP) on arterial function in subjects with resistant hypertension and severe OSA.

The impact of intradialytic pedaling exercise on arterial stiffness in a hemodialysis population
Objectives: Hemodialysis patients are at greater risk of increased arterial stiffness. Regular aerobic exercise has been shown to reduce arterial stiffness in hemodialysis patients. However, the impact of a more realistic intradialytic form of exercise, such as pedaling, is unclear. Therefore, we aimed to examine 1) the effect of intradialytic pedaling exercise on arterial stiffness over 4 months, and 2) the durability of the pedaling effect 4 months after finishing the exercise intervention.

Diabetes and central blood pressure in coronary patients
Background: Relative (represented by pulsatility) as well as absolute (pulse pressure) changes of central blood pressure (BP) were shown to predict cardiovascular (CV) complications in coronary patients. However, the influence of diabetes (a major CV risk factor) on the values of BP-derived indices is unknown. (Source: Artery Research)

How does obesity influence arterial stiffness in asymptomatic adults?
Central obesity is an important cause of cardiovascular disease. It's well-known that aortic pulse wave velocity (aoPWV) is a strong predictor of cardiovascular events. However the potential correlation between fat accumulation and increased arterial stiffness is poorly investigated. The aim of this study was to assess the association between obesity and aortic stiffness in normotensive adults. (Source: Artery Research)

Central pressures and wave reflections are independently associated with major adverse cardiovascular events in men with erectile dysfunction
Purpose: Erectile dysfunction (ED) confers an independent risk for cardiovascular events and total mortality. Central pressures and wave reflection indices independently predict cardiovascular events. Aim of this study is to investigate whether central haemodynamics predict major adverse cardiovascular events (MACEs) in ED patients beyond traditional risk factors. (Source: Artery Research)

Determinants of inappropriately high pulse wave velocity in hypertensive patients: a retrospective cross-sectional cohort study
Background: Age and blood pressure (BP) are known to be the main determinants of large artery stiffness. However other factors may lead to an inappropriately high pulse wave velocity (PWV). We investigated the determinants of inappropriately high PWV in hypertensive patients and their possible role in causing organ damage accrual. (Source: Artery Research)
