BACKGROUND AND PURPOSE Endothelium-derived NO is formed from L-arginine by endothelial NO synthase (eNOS) encoded by the NOS 3 gene on chromosome 7. Because several studies have indicated that NO plays a key role in the development of the atherosclerotic process, we investigated whether common variants in the eNOS gene are associated with an increased risk(More)
BACKGROUND Inadequate blood pressure (BP) control could be due to incorrect management of hypertensives caused by the lack of interaction between general practitioners (GP) and hypertension specialists. OBJECTIVES To test the effectiveness on BP and total cardiovascular risk (TCVR) control of an internet-based digital network connecting specialists and(More)
BACKGROUND In hypertension, reduced nitric oxide production and blunted endothelial vasorelaxation are observed. It was recently reported that AKT phosphorylates and activates endothelial nitric oxide synthase and that impaired kinase activity may be involved in endothelial dysfunction. METHODS AND RESULTS To identify the physiological role of the kinase(More)
OBJECTIVE This study compares the effects of an AT1 angiotensin II receptor antagonist (valsartan) with those of an ACE inhibitor (enalapril) on left ventricular (LV) diastolic function in patients with mild or moderate essential hypertension and no evidence of LV hypertrophy at echocardiography. METHODS A total of 24 patients (16 men, mean age 47 +/- 8(More)
Myocardial perfusion imaging (MPI) is important for the management of patients with suspected or known coronary artery disease (CAD). Nuclear cardiology is the most widely used noninvasive approach for the assessment of myocardial perfusion. The available single-photon emission computed tomography (SPECT) flow agents are characterized by a rapid myocardial(More)
Left ventricular (LV) mass (LVM) is the most important information requested in hypertensive patients referred for echocardiography. However, LV function also predicts cardiovascular (CV) risk independent of LVM. There is no evidence that addition of LV function significantly improves model prediction of CV risk compared with LVM alone. Thus, composite(More)
OBJECTIVES Although blood pressure is considered the major determinant of left ventricular hypertrophy in hypertension, genetic variability is increasingly being considered among the factors influencing this complication. beta(2)-Adrenergic receptors (beta(2)ARs) are up-regulated in hypertension and largely polymorphic within the human population. Recently,(More)
Barnidipine is a new 1,4-dihydropyridine calcium antagonist with a strong and long-lasting vasodilatory effect. In order to assess the haemodynamic profile of the antihypertensive effect of barnidipine, a randomized, double-blind study of barnidipine vs nitrendipine was performed in 24 patients with mild to moderate essential hypertension. Following an(More)
OBJECTIVE Cardiac and vascular remodeling occur in response to hypertension. Genetic background appears to modify the development of target organ damage (TOD). We evaluated the impact on hypertension-associated TOD of a highly polymorphic gene with elevated significance for the regulation of the cardiovascular system, the beta2AR gene. METHODS We(More)
OBJECTIVE To compare the effects of rilmenidine with those of amlodipine on blood pressure, glucose metabolism, plasma lipid concentration and fibrinolysis parameters. DESIGN A four-month randomized double-blind, parallel group study. PATIENTS AND METHODS Obese hypertensive patients with hypertriglyceridaemia (> or = 2.3 mmol/l) and impaired glucose(More)
