Aldosterone Levels, Aortic Stiffness, and Wave Reflection in Essential Hypertensive Patients.

Background: The aim of the present study was to evaluate the grade of arterial stiffening, in relation to aldosterone (ALDO) and plasma renin activity (PRA) levels, in essential never-treated hypertensive patients.

Materials And Methods: We studied 1,330 consecutive patients without clinical and/or laboratory findings of primary or secondary aldosteronism. Arterial stiffness indices Aix75 and carotid-femoral pulse wave velocity (PWVc-f) were measured and a 24-hour urine collection for ALDO was carried out to classify patients with low ALDO <12 mcg/24 hours and high ALDO >12 but <24 mcg/24 hours.

Impaired glucose homeostasis in non-diabetic Greek hypertensives with diabetes family history. Effect of the obesity status.

Arterial hypertension (AH) and diabetes mellitus (DM) are established cardiovascular risk factors. Impaired glucose homeostasis (IGH; impaired fasting glucose or/and impaired glucose tolerance) or pre-diabetes, obesity, and DM family history identify individuals at risk for type 2 DM in whom preventive interventions are necessary. The aim of this study was to determine the glycemic profile in non-diabetic Greek adult hypertensive men and women according to DM family history and the obesity status.

The interplay of exercise heart rate and blood pressure as a predictor of coronary artery disease and arterial hypertension.

Delayed blood pressure (BP) and heart rate (HR) decline at recovery post-exercise are independent predictors of incident coronary artery disease (CAD). Delayed BP recovery and exaggerated BP response to exercise are independent predictors of future arterial hypertension (AH). This study sought to examine whether the combination of two exercise parameters provides additional prognostic value than each variable alone.

Relationships of osteoprotegerin with albuminuria and asymmetric dimethylarginine in essential hypertension: integrating vascular dysfunction.

Objectives: To investigate the inter-relationships of osteoprotegerin (OPG) with albumin to creatinine ratio (ACR) and asymmetric dimethylargine (ADMA) in hypertensive patients.

Methods: In 198 untreated non-diabetic hypertensive patients [130 males, mean age=51.5 years, office blood pressure (BP)=152/98 mmHg] ACR values and OPG and ADMA levels were determined.

Ambulatory blood pressure profile in hypertensive patients with β-thalassemia minor.

β-thalassemia trait (β-TT) is a common genetic disorder in Mediterranean countries, including Greece. Previous studies have shown the protective effect of β-TT against myocardial infarction. However, the ambulatory blood pressure (BP) profile of such patients has not yet been investigated.

Prostate-specific antigen levels are associated with arterial stiffness in essential hypertensive patients.

Introduction: Prostate-specific antigen (PSA) has been recently related to cardiovascular system in a multifactorial way. Arterial stiffness is a independent predictor of cardiovascular events and is involved in the pathogenesis of hypertension. The aim of the present study was to investigate whether PSA values, are associated with arterial stiffness indices in patients with essential arterial hypertension.

Association of serum uric acid level with aortic stiffness and arterial wave reflections in newly diagnosed, never-treated hypertension.

Background: Serum uric acid (UA) plays a key role in the development and progression of hypertension. We investigated the association of UA levels and indices of arterial function in a cohort of newly diagnosed, never-treated hypertensive subjects.

Methods: One thousand two hundred and twenty-five patients with a new diagnosis of mild to moderate arterial hypertension for which they had never received treatment were enrolled in the study (mean age 52.

Serum phosphate in white-coat hypertensive patients: focus on dipping status and metabolic syndrome.

Recent studies indicate an association between serum phosphate levels and blood pressure in hypertensive patients. A growing body of evidence suggests that white-coat hypertension (WCH) is associated with target organ damage. Furthermore, metabolic syndrome (MS) and a non-dipping pattern are associated with increased cardiovascular risk.

Relationships of CRP and P wave dispersion with atrial fibrillation in hypertensive subjects.

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 index, sex and office systolic blood pressure (BP) subjects with no history of AF (SR group) were subjected to electrocardiogram (ECG) and P(disp) assessment, hs-CRP determination, a complete echocardiographic study and 24-h ambulatory BP monitoring.

Results: The AF as compared to the SR subjects were older by 14 years (P < 0.

Leontio Lyceum ALbuminuria (3L Study) epidemiological study: aims, design and preliminary findings.

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 habits.

Methods: During April 2009, 498 students from the Leontio Lyceum, aged 12-17 years (7th-12th grade), were asked to participate in the 3L Study.
