OBJECTIVES: Anorexia nervosa (AN) is characterized by marked neuroendocrine and autonomic dysfunctions. In the recent studies using automatic blood pressure monitoring (ABPM), lower BP values and lack of circardian variation of BP in anorectic patients were demonstrated. Unfortunately effects of hormonal changes, that may explain BP abnormalities were not analysed ...

BACKGROUND: The use of ambulatory recordings of blood pressure (BP) was proposed to estimate arterial stiffness (AS). We compared the relative value of the ambulatory AS index (AASI), and of the slope of pulse pressure (PP) according to mean BP (MBP) obtained from 24-h ambulatory BP monitoring, to the monitoring ...

Psychophysiological monitoring can be used to assess emotional reactivity in cardiovascular measures. Since blood pressure (BP) variability in daily life is primarily caused by physical activity, metabolic and nonmetabolic effects are confounded. A newly developed method of multiple accelerometry allows for the control of such unwanted variances by continuously detecting ...

Postprandial hypotension is an important clinical problem, particularly in the elderly. 5-Hydroxytryptamine3 (5-HT3) mechanisms may be important in the regulation of splanchnic blood flow and blood pressure (BP), and in mediating the effects of small intestinal nutrients on gastrointestinal motility. The aims of this study were to evaluate the effects ...

High blood pressure (BP) is one of the crucial determinants of the metabolic syndrome (MS). The extent to which MS, diagnosed according to the criteria of the International Federation of Diabetes, impacts on cardiovascular organ damage, independently of BP, is debated. Three hundred and forty hypertensive patients and 100 normotensive ...

BACKGROUND: Dialysate [Na+] is often overlooked as a contributor to hypertension in patients on haemodialysis (HD). We report observational experience with a facility level decrease in dialysate [Na+] from 141 mmol/l to 138 mmol/l, in the absence of concurrent change with respect to dietary sodium regulation. METHODS: The sample comprised ...

OBJECTIVE: Although tight blood pressure (BP) control is proven to reduce diabetes-related cardiovascular risk, it has been difficult to achieve in practice, perhaps in part because of low-quality monitoring data. We hypothesized that low-quality BP data, reflected in end-digit preference (EDP), remains common in primary care of diabetic adults. RESEARCH ...

In hypertensive hemodialysis (HD) patients, dry weight reduction to normalize blood pressure (BP) often results in increased frequency of HD hypotension. Because HD with blood volume tracking (BVT) has been shown to improve intra-HD hemodynamic stability, we performed a prospective, randomized study to test whether BVT is more effective than ...

Ambulatory blood pressure measurements (ABPM) correlate more closely with target organ damage and cardiovascular events than clinical cuff measurements. ABPM reveals the significant circadian variation in BP, which in most individuals presents a morning increase, small post-prandial decline, and more extensive lowering during nocturnal rest. However, under certain pathophysiological conditions, ...
