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)
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 Subclinical renal damage and hyperuricemia are not uncommon in patients with primary hypertension. Whether mild hyperuricemia reflects a subclinical impairment of renal function or contributes to its development is currently debated. We investigated the relationship between serum uric-acid levels and the occurrence of early signs of kidney(More)
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)
Increased arterial stiffness has been shown to predict cardiovascular mortality in patients with primary hypertension. Asymptomatic organ damage is known to precede cardiovascular events. We investigated the relationship between a recently proposed index of stiffness derived from ambulatory blood pressure (BP) and target organ damage in 188 untreated(More)
OBJECTIVE To assess the impact and cost-effectiveness of microalbuminuria and cardiovascular ultrasonography in evaluating the risk profile in primary hypertension. METHODS Four hundred and five untreated patients with primary hypertension underwent a routine, traditional work-up plus evaluation of albuminuria and ultrasound (US) assessment of cardiac and(More)
BACKGROUND Metabolic syndrome (MS) and chronic kidney disease (CKD) are well-known, independent predictors of increased cardiovascular risk. Both conditions are fairly prevalent in the general population. The aim of this study was to assess the relationship between MS or its individual components and CKD in an Italian population of hypertensive patients(More)
BACKGROUND Ultrasound (US) examination of heart and carotid arteries provides an accurate assessment of target organ damage (TOD) and may influence the stratification of the absolute cardiovascular risk profile. Microalbuminuria has recently proved to be a useful cost-effective marker of increased cardiovascular risk but is still too often neglected in(More)
OBJECTIVES Hypertensive patients with metabolic syndrome (MS) are at greater risk for cardiovascular disease. To get a better understanding of the pathophysiology underlying this association, we evaluated the relationship between MS and subclinical organ damage in essential hypertensive patients. DESIGN AND SETTING A total of 354 untreated, nondiabetic(More)
OBJECTIVE Microalbuminuria and a reduction in creatinine clearance are well known, independent predictors of unfavourable cardiovascular prognosis. Our aim was to evaluate the impact of renal damage on global risk stratification in 459 non-diabetic, untreated hypertensive patients (64% men, mean age 47.3 years). METHODS Renal damage was defined as(More)
