Between January 1987 and December 1989, 20 female patients with one mechanical valve prosthesis (MVP) for at least 1 year postoperatively were studied while on coumarin therapy for the full length of pregnancy. In each case, caesarean section was scheduled for the 38th week. Patients were selected according to the following criteria: (1) prothrombin ratios(More)
INTRODUCTION Atrial remodelling, leading to atrial fibrillation (AF), is mediated by the renin-angiotensin-aldosterone system. METHODS Mild hypertensive outpatients (systolic/diastolic blood pressure 140-159/90-99 mmHg) in sinus rhythm who had experienced ≥ 1 electrocardiogram (ECG)-documented AF episode in the previous six months received randomly(More)
Glibenclamide, a hypoglycemic sulfonylurea, is a blocker of the adenosine triphosphatase-modulated potassium ion channels. The opening of these channels in the myocardial cells, induced by acute myocardial hypoxia, can be responsible for ischemic ventricular arrhythmias. To evaluate the antiarrhythmic effects of this drug 19 non-insulin-dependent diabetic(More)
Antihypertensive efficacy, effects on left ventricular mass index (LVMI) and tolerability of telmisartan, an angiotensin II receptor blocker, were compared with those of hydrochlorothiazide (HCTZ). Adult patients with mild-to-moderate hypertension and an optimal acoustic window by two-dimensional echocardiography were randomised at baseline to 12 months'(More)
In 44 patients affected by systemic lupus erythematosus (SLE) without any clinical signs of heart disease (group I) the myocardial performance index (MPI) was calculated to investigate left ventricular function. The index, as the sum of isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by ejection time (ET), was measured(More)
Previous studies have demonstrated that insulin resistance is a common feature of congestive heart failure (CHF), but the clinical significance of such insulin resistance is still debated. We tested the hypothesis that insulin-mediated glucose uptake (IMGU) is a prognostic factor in CHF in aged patients. For this purpose 174 aged patients with CHF(More)
OBJECTIVE To identify the sequence and significance of left ventricular filling abnormalities associated with progressive aging in humans. DESIGN Cross-sectional study comparing three age groups. SETTING Department of Geriatrics at University of Naples. PARTICIPANTS Seventy-five healthy subjects in three age groups: 25 subjects from 25 to 45 years(More)
Blockade of the renin-angiotensin system is an important approach in managing high blood pressure, and has increasingly been shown to affect cardiovascular disease processes mediated by angiotensin II throughout the cardiovascular and renal continua. Telmisartan is an angiotensin II receptor blocker (ARB) displaying unique pharmacologic properties,(More)
BACKGROUND The hypothesis that left ventricular hypertrophy regression in hypertension relates to blood pressure (BP) control and to non-antihypertensive activity of some drugs was tested by comparing the effects of telmisartan and carvedilol on 24-h mean ambulatory BP and left ventricular mass (LVM) regression, measured using three-dimensional(More)
In newly-diagnosed untreated (n = 24) and thiazide treated (n = 18) hypertensive patients erythrocyte ion content and plasma ion and metabolite levels were determined. Thiazide treated patients had lower arterial blood pressure, plasma ion levels, erythrocyte magnesium and potassium content but higher fasting plasma insulin (66 +/- 7 v 87 +/- 8 pmol/L P <(More)
