UNLABELLED This study was performed to determine the secretion pattern and prognostic value of A-type (ANP) and B-type (BNP) natriuretic peptide in patients undergoing cardiac surgical procedures. We measured ANP and BNP in patients undergoing coronary artery bypass grafting (CABG) with (n = 28) or without (n = 32) ventricular dysfunction and in patients undergoing mitral (n = 21) or aortic (n ...

BACKGROUND B-type natriuretic peptide (BNP) is an endogenous peptide produced under physiological and pathological conditions mainly by ventricular myocytes. It has natriuretic, diuretic, blood pressure-lowering, and antifibrotic actions that could mediate cardiorenal protection in cardiovascular diseases. In the present study, we used BNP gene transfer to examine functional and structural effe...

introduction: pulmonary arterial hypertension (pah) is a late progressive sclerodermarelated complication, which can lead to right heart failure and cor pulmonale. given that cardiac catheterization is a diagnostic method of choice for pah, and considering the high risks of this method, the purpose of this study was to evaluate the relationship between serum pro‐brain natriuretic peptide (pro‐b...

AIMS To assess the value of a near-patient brain natriuretic peptide (BNP) test to predict medium term (3 month) serious outcome for adult syncope patients presenting to a UK emergency department (ED). METHODS This was a prospective cohort pilot study. Consecutive patients aged > or = 16 years presenting with syncope over a 3 month period were eligible for prospective enrolment. All patients ...

BACKGROUND In patients with symptoms of heart failure, elevations in B-type natriuretic peptide (BNP) accurately identify ventricular dysfunction. However, BNP levels are not specific for ventricular dysfunction in patients who do not have overt symptoms of heart failure, suggesting that other cardiac processes such as myocardial ischemia may also cause elevations in BNP. METHODS AND RESULTS ...

OBJECTIVE Brain natriuretic peptide (BNP) is a cardiac hormone mainly synthesized in ventricles and its expression is markedly increased in ventricular hypertrophy that involves the accumulation of extracellular matrix proteins, such as fibronectin (Fn). We recently reported that Fn signaling stimulated BNP secretion accompanied by hypertrophic responses in vitro. METHODS To elucidate the reg...

OBJECTIVES This study sought to investigate the influence of right ventricular (RV) hemodynamic variables and function on the secretion of brain natriuretic peptide (BNP) in patients with isolated RV overload. BACKGROUND Plasma BNP is known to increase in proportion to the degree of left ventricular (LV) overload. However, whether BNP secretion is also regulated in the presence of RV overload...

Elevated plasma natriuretic peptide levels after AMI (acute myocardial infarction) are associated with adverse outcome. The aim of the present study was to examine the relationship of plasma N-ANP (N-terminal pro-atrial natriuretic peptide) and N-BNP (N-terminal pro-B-type natriuretic peptide) with mortality and heart failure following AMI. We studied 403 patients with AMI. Blood was sampled fo...

Background—In patients with symptoms of heart failure, elevations in B-type natriuretic peptide (BNP) accurately identify ventricular dysfunction. However, BNP levels are not specific for ventricular dysfunction in patients who do not have overt symptoms of heart failure, suggesting that other cardiac processes such as myocardial ischemia may also cause elevations in BNP. Methods and Results—To...

The key management goals for the stabilization of patients admitted for acutely decompensated heart failure (ADHF) include relief of congestion and restoration of hemodynamic stability. Nevertheless, in spite of clinical improvement, many patients are discharged with hemodynamic congestion. In response to volume expansion, the heart secretes the brain natriuretic peptide (BNP) with a biological...
