BACKGROUND Increased renal resistance detected by ultrasound (US) Doppler has been reported in severe essential hypertension (EH) and recently was shown to correlate with the degree of renal impairment in hypertensive patients with chronic renal failure. However, the pathophysiological significance of this finding is still controversial. METHODS In a(More)
Segmental anatomy has been investigated on 54 pig livers by bench-top radiology and ultrasonography of hepatic and portal vessels and bile ducts and dissection of suprahepatic veins. Eight segments were recognized, homologous to those of the human liver. Major variations were found only of arterial distribution. The inferior vena cava invariably ran within(More)
The Doppler-derived renal resistive index has been used for years in a variety of clinical settings such as the assessment of chronic renal allograft rejection, detection and management of renal artery stenosis, evaluation of progression risk in chronic kidney disease, differential diagnosis in acute and chronic obstructive renal disease, and more recently(More)
BACKGROUND Mild renal dysfunction (MRD) is an often overlooked but relatively common condition in patients with primary hypertension (PH), and is associated with high cardiovascular morbidity and mortality. Whether MRD is also associated with abnormalities in renal vascular resistance is currently unknown. METHODS Two hundred ninety-one untreated patients(More)
The role of serum uric acid as an independent risk factor for cardiovascular and renal morbidity is controversial. A better understanding of its relationship with preclinical organ damage may help clarify the mechanism(s) implicated in the development of early cardiovascular disease. We evaluated the association between uric acid and the presence and degree(More)
BACKGROUND AND OBJECTIVES Increased urinary albumin excretion is a known risk factor for cardiovascular events and clinical nephropathy in patients with diabetes. Whether microalbuminuria predicts long-term development of chronic renal insufficiency (CRI) in patients without diabetes and with primary hypertension remains to be documented. DESIGN, SETTING,(More)
High sensitivity C-reactive protein (hs-CRP) has been recognized as a risk factor for cardiovascular disease. Asymptomatic organ damage is known to precede cardiovascular events in hypertension. The aim of the present study was to investigate the relationship between hs-CRP and signs of organ damage, namely left ventricular mass index (LVMI), albuminuria,(More)
OBJECTIVE Arterial stiffness is a predictor of cardiovascular mortality in the general population as well as in hypertension and end-stage renal disease. We investigated the relationship between a recently proposed ambulatory blood pressure monitoring-derived index of arterial stiffness and early signs of renal damage in patients with primary hypertension.(More)
Microalbuminuria is defined as abnormal urinary excretion of albumin between 30 and 300 mg/d. It can be measured accurately by several widely available and sensitive methods. This abnormality can be found in 8 to 15% of nondiabetic patients with primary hypertension, although its prevalence varies greatly in the literature, likely due to differences in the(More)
BACKGROUND High pulse pressure (PP) values have recently been implicated in the development and progression of large vessel atherosclerosis, small vessel disease, and in the occurrence of cardiovascular events. The aim of the present study is to investigate the relationship between PP and subclinical cardiovascular damage in a cohort of unselected(More)
