Congestive heart failure (CHF) is associated with an impaired flow-mediated vasodilation that reflects an impaired endothelial function. Limited information is available, however, on whether and to what extent this impairment is improved by pharmacological or nonpharmacological treatment. We measured radial artery diameter and blood flow by an echo-tracking(More)
OBJECTIVES Previous studies have shown that left ventricular hypertrophy (LVH) represents a cardiovascular risk factor independently of clinic blood pressure (BP). The present study was aimed at determining the impact of LVH on the incidence of cardiovascular morbid and fatal events taking into account not only classical risk factors but also home and(More)
Diabetes is associated with a reduction of arterial distensibility. Limited information exists regarding whether or how early this appears in the course of the disease. We studied 54 normoglycemic, normotensive, healthy offspring of 2 parents with type 2 diabetes mellitus and 55 age- and sex-matched healthy control subjects. Carotid diastolic diameter and(More)
Prevalence of left atrial enlargement (LAE) in hypertension has been mostly assessed in population-based samples and selected hypertensive groups. A few data are available in clinical practice. We examined LAE prevalence and severity in a cohort of hypertensive patients referred by general practitioners to a routine echocardiographic examination. A total of(More)
The subjects were 36 hypertensive patients aged 61 to 79 years (mean, 66 years). After a placebo run-in period of one month, each patient was randomly assigned to two months of treatment with 100 mg of metoprolol, 50 mg of captopril, or 25 mg of hydrochlorothiazide plus 2.5 mg of amiloride daily, or placebo. The doses were doubled if diastolic pressure was(More)
The antihypertensive efficacy and subjective and physical tolerability of three different pharmacological treatments (metoprolol, captopril and the combination of hydrochlorothiazide + amiloride) were compared with placebo in 36 elderly hypertensives (aged 61-79 years), according to a Latin-square double-blind design. The placebo and the active treatments(More)
A randomized controlled open trial studied the effect of vitamin E supplementation (300 mg/day) on clinic and 24-h ambulatory blood pressure (BP) in 142 treated hypertensive patients. After 12 weeks, clinic BP decreased whether or not patients were randomized to vitamin E. Ambulatory BP showed no change in systolic BP and a small decrease in diastolic BP(More)
OBJECTIVE Hypercholesterolemia markedly impairs endothelial function. Whether this is the case for hypertriglyceridemia is less clear, however, and limited evidence exists on the effect of an acute increase in triglyceridemia caused by a high-fat meal. METHODS AND RESULTS In 16 normotensive subjects with an untreated mild hypertriglyceridemia and(More)
Studies in animals and humans suggest that sympathetic activity exerts a stiffening influence on large and middle-sized artery walls. We sought to obtain further evidence on this issue by measuring radial artery distensibility in an allotransplanted and thus denervated hand using the contralateral artery as control. In 2 men, blood pressure was measured by(More)
UNLABELLED objectives; The aim of this study was to determine whether in patients with congestive heart failure (CHF) a distensibility (Dist) reduction: 1) similarly occurs in different arteries; 2) is related to CHF severity; and 3) is reversible with treatment. background: Several studies suggest that CHF is accompanied by a reduced arterial Dist.
