The classification of subjects as nocturnal hypertensives in accordance with non-dipping (i.e. systolic blood pressure - BP - fall <10%) is less reproducible as compared to the fixed cut-off limits method (nocturnal BP means >120/70 mm Hg). The present study was carried out to assess if nocturnal hypertension defined by ...

Growing evidence associates blood pressure (BP) variability with cardiovascular events in hypertensive patients. Here we tested the existence of a relationship between awake BP variability and target-organ damage in subjects referred for suspected hypertension. Systolic and diastolic BP variability were assessed as the standard deviation of the mean out of ...

Impaired recovery and plasma concentration of intercellular adhesion molecule-1 (sICAM-1) were both highlighted as plausible and more established markers of cardiovascular disease, respectively. Hemodynamic patterns during recovery and their link with circulating levels of sICAM-1 were examined as predictors of 24-h blood pressure (ABP). Impedance cardiography measures and beat-to-beat BP ...

BACKGROUND: Although the acute increase of arterial stiffness and blood pressure (BP) after cigarette smoking in healthy smokers is considered a possible mechanism of increased cardiovascular risk, the acute effect of smoking on arterial stiffness in hypertensive smokers is unknown. We investigated the acute effects of cigarette smoking on arterial ...

The ankle brachial index (ABI) has been widely used to monitor the pathogenesis of peripheral arterial diseases such as ischemia of the extremities. Owing to the occluding nature of ABI measurement, this may not be appealing to less cooperative patients when multiple prolonged screening is required. Recently, a simple non-occluding ...

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, ...

BACKGROUND: Correction of anemia by erythropoietin (EPO) is often associated with a rise in blood pressure (BP; EPO-induced hypertension). Most studies regarding EPO-induced hypertension have involved evaluation using office/clinic BP (OBP). However, recent investigations suggest that BP measured at home (HBP) may be of more importance for clinical practice in ...
