BACKGROUND Although inflammation has been shown to be implicated in the pathophysiology of atrial fibrillation (AF), little is known about its involvement in the accompanying atrial electrical remodeling expressed by P wave dispersion (P(disp)). METHODS Fifty hypertensive subjects with documented paroxysmal AF (AF group) and 50 matched for body mass(More)
OBJECTIVE The clinical significance of masked hypertension (MHT) and white-coat hypertension (WCHT) remains controversial, whereas subclinical inflammation and arterial stiffness are associated with an adverse prognosis. We examined the interrelationships of MHT, WCHT, and sustained hypertension (SHT) with high-sensitivity C-reactive protein (hs-CRP) and(More)
OBJECTIVE Beneficial effects of continuous positive airway pressure (CPAP) on both blood pressure (BP) levels and variability have been documented in patients with obstructive sleep apnoea (OSA). We investigated the relevant impact of different dosing times of antihypertensive drugs beyond CPAP application. METHODS In this prospective, cross-over trial,(More)
BACKGROUND We aimed to investigate the predictive role of left ventricular mass and its reduction on the development of new-onset microalbuminuria (MA) in newly diagnosed hypertensive patients. METHODS A total of 207 nondiabetic, normoalbuminuric patients without clinical organ damage (aged 50.8 ± 10.1 years, 132 male, 84 smokers) with baseline office(More)
At present, clinic blood pressure (BP) evaluation is being increasingly complemented by ambulatory BP measurements for the evaluation of haemodynamic patterns during daily activities and sleep. Nondipping pattern, a measure of decreased attenuation of nighttime over daytime BP, has been correlated with enhanced target organ damage and adverse cardiovascular(More)
Both blood pressure (BP) non-dipping and nighttime hypertension have been associated with accelerated target-organ damage (TOD). However, increased nighttime BP in subjects with a dipping circadian BP profile has never been reported or associated with TOD. Here, we investigated the relationships of nighttime BP with indices of vascular and kidney damage in(More)
INTRODUCTION The significance of microalbuminuria (MA) in paediatric essential hypertension has yet to be established. The Leontio Lyceum ALbuminuria Study (3L Study) was designed to determine the prevalence of MA among Greek schoolchildren and to evaluate these rates in relation to the children's anthropometric and lifestyle characteristics, and dietary(More)
Different studies have addressed the predictive role of nighttime hemodynamics on cardiovascular and renal outcomes, although nocturnal blood pressure (BP) phenotypes (i.e. nondipping pattern and absolute nocturnal BP) have been found to be predictive of worse health outcomes. Furthermore, differences in both examined populations - ranging from healthy and(More)
ABPM constitutes a valuable tool in the diagnosis of RH. The identification of white coat RH and masked hypertension (which may fulfill or not the definition of RH) is of great importance in the clinical management of such patients. Moreover, the various ABPM components such as average BP values, circadian BP variability patterns, and ambulatory BP-derived(More)
OBJECTIVE The association of resistant hypertension (RHTN) with renal haemodynamics is unclear. Our aim was to evaluate differences in haemodynamic characteristics of patients with RHTN compared with patients with controlled hypertension (HTN) at the level of the heart, kidney and aorta. METHODS We studied 50 patients with RHTN confirmed by ambulatory(More)
