COMPARAZIONE DELLE RELAZIONI DI DIFFERENTI DEFINIZIONI DI SINDROME METABOLICA CON L'IPERTROFIA VENTRICOLARE SX NELL'IPERTENSIONE ESSENZIALE

Numerosi studi hanno dimostrato che la sindrome metabolica (SM), sia quando definita secondo i criteri dell'ATPIII, sia quando definita secondo i criteri dell'IDF, si associa ad un aumento della massa del ventricolo sx (VS). Tuttavia, non è noto se queste due differenti definizioni di SM abbiano la stessa capacità di identificare l'ipertrofia del VS (IVS) . Inoltre, una delle critiche mosse al concetto di SM è legata al fatto di essere una variabile dicotomica, limitando in tal modo la possibilità di definire la gravità del rischio cardiovascolare nel singolo paziente. Scopo del nostro studio è stato quello di valutare comparativamente la capacità di differenti definizioni di SM di identifi…

Comparison of the relationship among different defintions of metabolic syndrome and left ventricular hypertrophy in essential hypertension

Association of Oxidative Stress with Aortic Stiffness in Hypertensive Patients with Chronic Kidney Disease

Several studies have consistently demonstrated that arterial stiffness becomes progressively worse as CKD progresses and a negative correlation of oxidative stress with renal function has been described. There is also sound experimental evidence indicating that oxidative stress is involved in atherogenesis. The contribution of oxidative stress to aortic stiffness is less clear. Aim: To analyse the relationship between plasma levels of 8-ISO-prostaglandin F2alpha (8-ISOPGF2alpha), an index of lipid peroxidation, considered a reliable biomarker of oxidative stress, and aortic stiffness in a group of hypertensive patients with chronic kidney disease. Methods: We enrolled 126 hypertensive patie…

Relationship between obesity and plasma aldosterone in essential hypertension: influence of gender

SHORT-TERM VARIABILITY OF 24-H SYSTOLIC BLOOD PRESSURE IS ASSOCIATED WITH MICROALBUMINURIA IN PATIENTS WITH PRIMARY HYPERTENSION

Introduction: Limited and conflicting data are available about the association between short-term blood pressure (BP) variability and urinary albumin excretion rate (uAER). Aim: To analyse the relationships between microalbuminuria, defined as an uAER between 20 and 200 lg/min, and short-term BP variability, assessed as average real variability (ARV), weighted standard deviation (SD) of 24-h BP, and as SD of daytime and nighttime BP. Methods: The study population consisted of 316 untreated essential hypertensive patients with normal estimated glomerular filtration rate ([60 ml/min/1.73m2), which underwent 24-h ambulatory BP monitoring and 24-h uAER determination. Results: Microalbuminuria w…

Relationship between aortic stiffness and serum uric acid in essential hypertension

In last years hyperuricemia has been associated with an increased incidence of renal and cardiovascular events in general population, as well as in patients with diabetes and hypertension. However, the role of serum uric acid (SUA) as independent cardiovascular risk factor is still controversial. It is well known that increased aortic stiffness is a powerful independent predictor of cardiovascular events. Little is known about the influence of uric acid on aortic distensibility in subjects with arterial hypertension. The aim of our study was to evaluate the relationships between SUA and aortic stiffness in a group of essential hypertensive patients, attending our Hypertension Centre. We enr…

Microalbuminuria Is Associated With Aortic Stiffness Independently of Creatinine Clearance in Essential Hypertension

Relazione tra stiffness aortica ed uricemia nell'ipertensione arteriosa essenziale

Relazione tra obesità ed aldosteronemia nell'ipertensione essenziale: influenza del sesso.

Una relazione tra obesità e aldosteronemia (ALD), indipendente dall’attività reninica plasmatica (PRA), è stata ipotizzata sulla base di diverse evidenze sperimentali, ma non è stata confermata in tutti gli studi clinici effettuati sull’argomento. Inoltre, pochi dati esistono in letteratura sull’eventuale influenza del sesso su tale relazione. Scopo del nostro studio è stato quello di esaminare, prima globalmente e poi separatamente nei due sessi, l’eventuale associazione tra indice di massa corporea (BMI), circonferenza addominale (W) e ALD in un ampio gruppo di ipertesi essenziali non diabetici, afferenti al nostro Centro di Riferimento per lo studio dell’Ipertensione Arteriosa. Sono stat…
