The significance of nondipping and increased nighttime systolic blood pressure (SBP) in established hypertension is well defined. We investigated whether these factors alone or combined correlate with vascular damage in early-stage hypertension. Newly diagnosed, untreated hypertensives were classified as dippers and nondippers according to ambulatory blood pressure (BP). Twenty-four-hour urinary albumin excretion and markers of arterial stiffness (pulse wave velocity, augmentation index, central and peripheral pulse pressure, central BP) and atherosclerosis (carotid intima-media thickness) were assessed...

PURPOSE: Arterial stiffness has predictive value for cardiovascular disease (CVD). Local artery stiffness can provide insight on CVD pathology and may be useful for diagnosis and prognosis. However, current methods are invasive, require real-time expertise for measurement, or are limited by arterial region. 4D Flow MRI can non-invasively measure local stiffness by estimating local pulse wave velocity (PWV). This technique can be applied to vascular regions, previously accessible only by invasive stiffness measurement methods...

Aortic pulse-wave-velocity (aPWV) is a measure for arterial stiffness, which is associated with increased cardiovascular risk. Recent evidence suggests aPWV increases after endograft-placement for aortic aneurysms. The aim of this study was to investigate the influence of different aortic endoprostheses on aPWV and structural stiffness in vitro. 
 Approach: Three different abdominal aortic endoprostheses (AFX, Endurant II, and Nellix) were implanted in identical silicone aneurysm models. One model was left untreated, and another model contained an aortic tube graft (Gelweave)...

The velocity of the pulse wave (PWV) propagating through the vascular tree is an essential parameter for diagnostic the state of the cardiovascular system especially when it is measured in the pool of carotid arteries. In this research, we showed for the first time that the time of the blood-pressure-wave propagation from the heart to the face is a function of the body position. Significant asymmetry and asynchronicity of blood pulsations in the facial area were found in a recumbent position. Parameters of blood pulsations were measured by an advanced camera-based photoplethysmography system in 73 apparently healthy subjects...

Obesity modifies the association between sodium and potassium intake and blood pressure. However, the impact of obesity on the relationship between the sodium-potassium balance and cardiovascular risk in type 2 diabetes (T2DM) patients remains unclear. We investigated the relationship between the 24-h urinary sodium-to-potassium ratio and serum asymmetric dimethylarginine (ADMA) level, which is a cardiovascular risk factor, in Japanese T2D patients with or without obesity. This cross-sectional study included 243 patients with T2DM who were hospitalized for diabetes education...

BACKGROUND: During normal pregnancy, placental oxidative stress (OS) is present during all three trimesters and is necessary to obtain normal cell function. However, if OS reaches a certain level, pregnancy complications might arise. In preeclampsia (PE), a dangerous pregnancy specific hypertensive disorder, OS induced in the ischemic placenta causes a systemic inflammatory response and activates maternal endothelial cells. In this study, we aimed to quantify superoxide concentrations (as a measure of systemic OS) using electron paramagnetic resonance (EPR) and correlate them to markers of systemic inflammation, iron status and vascular function...
