1. A family of structurally related but genetically distinct natriuretic peptides exist which include atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) of myocardial cell origin and C-type natriuretic peptide (CNP) of endothelial and renal epithelial cell origin. All three exert actions via cGMP, with ANP and BNP functioning via the natriuretic peptide A receptor and CNP via ...

ObjectiveThis study aimed to assess Brain Natriuretic Peptide in early diagnose of cardiac function in children with Congenital Heart Diseases.MethodologyThis study was performed on children with CHD and healthy. Severity of heart failure modified Ross classification system was used for grouping patients in four classes. For all participants, height, weight and head circumference were measured....

INTRODUCTION AND OBJECTIVES Hypertension is a risk factor for atrial fibrillation. Activation of the renin-angiotensin-system seems to be involved in atrial enlargement, with release of atrial and brain natriuretic peptides. The aim of this study was to evaluate the relationship between ambulatory blood pressure and levels of natriuretic peptides, with left atrial size in normotensives with idi...

Background and Aims: There has been scant information concerning antihypertrophic effects of vitamin D specifically on its cellular and molecular mechanisms. Sirtuin 1 (SIRT1) is regarded as a key deacetylase enzyme in cardiomyocytes which applies potential cardioprotective effects by functional regulation of different proteins. This study aimed to evaluate the effects of 1, 25-dihydroxyvitamin...

Natriuretic peptides and the reninangiotensin-aldosterone system (RAAS) have reciprocal effects at multiple sites and in varied situations. They interact in health and cardiovascular disease to influence renal, endocrine, and haemodynamic function and cardiovascular cell growth. The atrial natriuretic peptide (atrial natriuretic factor, ANF) discovered by De Bold in 19811 was cloned and sequenc...

BACKGROUND Off-pump coronary artery bypass surgery is considered to be less invasive compared with a conventional coronary artery bypass surgery, while objective assessment of its invasiveness has not been well established. The grade of invasiveness of off-pump CABG was evaluated by biochemical markers released from the myocardium. METHODS Perioperative serial changes of myocardial enzyme lea...

BACKGROUND The compensatory actions of the endogenous natriuretic peptide system require adequate processing of natriuretic peptide pro‐hormones into biologically active, carboxyl‐terminal fragments. Natriuretic peptide pro‐peptide processing is accomplished by corin, a transmembrane serine protease expressed by cardiomyocytes. Brain natriuretic peptide (BNP) processing is inadequate in advance...
