BACKGROUND AND PURPOSE Cerebral hypoperfusion has occasionally been reported during essential hypertension. We explored regional cerebral blood flow in a large series of neurologically asymptomatic hypertensive patients to determine relations among cerebral blood flow, concomitant main vascular risk factors, and the most common signs of end-organ damage.

The actual reference range of serum uric acid has been assessed according to its variations among healthy individuals. i.e. those without clinical evidence of gout. By this approach, serum uric acid values between 3.5 and 7.2 mg/dL in adult males and postmenopausal women and between 2.6 and 6.0 mg/dL in premenopausal women have been identified as normal in(More)
OBJECTIVE Antihypertensive treatment and blood pressure (BP) reduction are known to retard the progression of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) but long-term real-life clinical data on the incidence of DKD are lacking. In this observational, prospective cohort study, we investigated the association between achievement and(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)
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 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)
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)
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)
In erythrocytes of patients with essential hypertension the level of calpastatin activity was found to be significantly lower than in red cells of normotensive subjects (1). We now demonstrate, by Western blot analysis, that the decreased inhibitory activity is due to a corresponding decrease in the amount of the inhibitor protein. This is also supported by(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)
