BACKGROUND Previous studies have shown that metabolic syndrome (MS) is associated with an increased susceptibility to develop cardiovascular damage (CD). Experimental evidence indicates that inflammation and fibrosis could play a critical role in the development of CD in hypertension. This issue has not been clarified yet in patients with MS. The aim of our(More)
OBJECTIVES The goal of our study was to investigate the relationships between atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and type A natriuretic peptide receptor (NPRA) gene polymorphisms and left ventricular structure in human essential hypertension. BACKGROUND Experimental evidence supports a key role for natriuretic peptides in(More)
OBJECTIVES The metabolic syndrome (MS) is associated with left ventricular hypertrophy (LVH). Previous evidence has shown that LVH is favoured by low levels of atrial natriuretic peptide (ANP), independently from blood pressure (BP), in hypertension. Although levels of natriuretic peptides are known to be lower in obesity, plasma ANP levels have not yet(More)
BACKGROUND Vasoconstrictive, proliferative and oxidative effects of angiotensin II (Ang II) are mediated by Ang II type 1 (AT1) receptors. The effects of Ang II via the Ang II type 2 (AT2) receptor subtype (AT2R) are less well defined. Growing evidence shows the existence of cross-talk between the Ang II receptor subtypes, which is revealed by AT1R(More)
Endothelial dysfunction, intended as the complex multifaced pathological product of different vasculotoxic agents or injuries, is viewed today as an attractant intermediate phenotype of cardiovascular diseases with usually long and unpredictable natural history. Furthermore, endothelial dysfunction may not only represent a vascular disease marker, but may(More)
To investigate the functional relevance of a regulatory mutation affecting the enhancer element PEA2 of the rat ANP gene we transfected rat cardiomyocytes and aortic endothelial cells with either the mutant or the wild-type ANP promoter construct (-683 +54) and performed CAT assays both at baseline and in response to Phenylephrine and Angiotensin II. In the(More)
