Relazione tra disfunzione erettile, livelli di testosterone e funzione endoteliale in pazienti a rischio cardiovascolare intermedio secondo le stime …
2014
Scopo del lavoro Il ruolo dei livelli di testosterone plasmatico e della disfunzione erettile come marcatori precoci di disfunzione endoteliale non è ben definito. Pertanto, abbiamo cercato di analizzare la relazione tra testosterone plasmatico e disfunzione erettile, in rapporto alla funzione endoteliale. Materiali e metodi Abbiamo quindi arruolato 802 pazienti in prevenzione primaria, con una stima di rischio cardiovascolare (CV) intermedio secondo la carta del rischio di Framingham, di età compresa fra 40 e 80 anni, che si sono sottoposti all’esame ecografico della dilatazione flusso mediata dell’arteria brachiale destra, alla valutazione della disfunzione erettile attraverso il question…
A GIANT ANEURYSM OF PROPER HEPATIC ARTERY IN A CRYOGLOBULINEMIC PATIENT ON HEMODIALYSIS: A CASE REPORT.
2014
Introductrion. Hepatic artery aneurysms (HAAs) are unusual vascular lesions often associated with many different pathological conditions. Most of reported cases are described in association with connective tissue diseases, such as polyarteritis nodosa and systemic lupus erythematosus. Case report. We observed a 52-year-old man with hypertension and HCV-related cryoglobulinemia complicated by end stage renal disease on replacement therapy by hemodialysis. He was admitted to our hospital because of the worsening of blood pressure values (170/110 mmHg) associated to new onset abdominal pain. After an initial physical examination, that showed a periumbelical bruit associated to a pulsatile mass…

BRUGADA PATTERN IN HEROIN ADDICTION: SYNDROME OR PHENOCOPY?
2020
Brugada phenocopies (BrPs) are clinical entities that show an electrocardiogram (ECG) pattern similar to what is observed in Brugada syndrome (BrS). They are caused by different clinical conditions. We describe a case of BrP in a man that developed acute kidney failure secondary to rhabdomyolysis, after heroin addiction. His initial ECG showed Brugada type 1 pattern resolved after hemodialytic treatment. A provocative test with ajmaline, which resulted negative, was performed to confirm the diagnosis. BrPs can mimic a true BrS and a fast recognition of these clinical and electrocardiographic findings may avoid diagnostic mistakes thus preventing unnecessary or inaccurate treatmen
PLASMA ENDOTHELIN-1 IS ASSOCIATED WITH AORTIC STIFFNESS IN ESSENTIAL HYPERTENSION
2011
Background: Experimental studies documented that endothelin-1 (ET-1) contributes to arterial stiffness and recently, in patients with chronic kidney diseases, it has been observed that selective endothelin-A receptor antagonism reduces arterial stiffness, in part independently of blood pressure lowering. Little is known about the relationships between ET-1 plasma levels and aortic distensibility in subjects with essential hypertension. Objective: The aim of our study was to analyse the relationships between plasma concentrations of ET-1 and carotid-femoral pulse wave velocity (c-f PWV), as an index of aortic stiffness, in a group of hypertensive patients without overt renal insufficiency [e…
Effects of amlodipine on renal haemodynamics in mild to moderate hypertensive patients. A randomized controlled study versus placebo. Eur J Clin Phar…
1993
In this study the efficacy and safety of short-term amlodipine administration on renal haemodynamics were evaluated in mild to moderate hypertensive subjects. Our final goal was to evaluate whether the reduced blood pressure induced by treatment was associated with maintenance of renal function. After a run-in period with placebo, 30 hypertensive patients without cardiac or renal diseases were randomly allocated to a double-blind 4 weeks controlled study with amlodipine 10 mg once a day (15 patients) or placebo (15 patients). Renal haemodynamic measurements included effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) by radionuclide study using 131I-hippuran and 99mTc, w…
[OP.7D.07] 24-HOUR CENTRAL BLOOD PRESSURE IS BETTER ASSOCIATED WITH TARGET ORGAN DAMAGE OF HYPERTENSION THAN BRACHIAL BLOOD PRESSURE
2017
Objective: The VASOTENS international, multicenter, observational, non-randomized, prospective study aims at evaluating the impact of 24-hour pulse wave analysis of ambulatory blood pressure (BP) recordings on target organ damage and cardiovascular prognosis of hypertensive patients. In the present analysis of study baseline data we checked whether organ damage of hypertension i) is better associated with 24-hour central than peripheral BP and ii) is related to ambulatory arterial stiffness, estimated by pulse wave velocity (PWV) and augmentation index (AIx). Design and method: In 334 hypertensive patients (mean age 53+/-15, 52% males, 45% treated) we obtained 24-hour ABPMs, echocardiograms…
DIFFERENTE IMPATTO NEI DUE SESSI DELL’OBESITÀ SULLA MASSA VENTRICOLARE SINISTRA IN SOGGETTI CAUCASICI CON IPERTENSIONE ARTERIOSA ESSENZIALE
2014
Dati non univoci sono riportati in letteratura sul ruolo della dislipidemia nello sviluppo dell’ipertrofia ventricolare sinistra. Scopo del nostro studio, è stato quello di valutare le potenziali associazioni dei principali parametri lipidici con la massa ventricolare sinistra (LVM) in pazienti con ipertensione essenziale (EHs). Abbiamo arruolato 724 soggetti con EH (età media 45±12 anni; 63% maschi), senza complicanze cardiovascolari e non trattati con farmaci ipolipemizzanti. In tutti i soggetti dono stati dosati la colesterolemia totale (Tchol), la trigliceridemia (TG) e il colesterolo HDL (HDLc). Il colesterolo LDL (LDLc) è stato stimato con la formula di Friedewald ed è stato calcolato…
INVERSE RELATIONSHIP BETWEEN AORTIC ROOT DIAMETER AND RENAL FUNCTION IN HYPERTENSIVE SUBJECTS
2015
Introduction: Dilatation of aortic root is associated with presence and severity of aortic regurgitation and risk for aortic dissection. Recent studies performed in general population suggest that enlarged aortic root diameter (ARD) may predict cardiovascular events in absence of aneurysmatic alterations. Little is known about the influence of renal function on ARD. Aim: To assess the relationships between glomerular filtration rate (GFR) and ARD in hypertensive subjects. Methods: We enrolled 611 hypertensive individuals (mean age: 52 ± 15 years; men 63 %) consecutively attending our outpatient nephrology and hypertension unit. Patients on dialysis treatment, with valvulopathy more than mil…
BILATERAL RENAL ARTERY STENOSIS IN A HYPERTENSIVE LUPUS PATIENT WITHOUT RENAL DYSFUNCTION: A CASE REPORT
2014
Systemic lupus erythematosus (SLE) is associated with a high prevalence of atherosclero-sis and an enhanced cardiovascular mortality. In adult subjects, several studies have shown the coexistence of SLE and renal artery stenosis, most of them with unilateral in-volvement or with renal dysfunction. We observed a 62-year-old man with SLE and a 10-year history of moderate-to-severe hy-pertension who was admitted to our hospital because of uncontrolled blood pressure val-ues (152/95 mmHg), despite drug therapy. No signs of renal impairment were evident. After an initial physical examination, which presented a periumbilical bruit, a renal ultra-sound was performed with evidence of bilateral rena…
