Background: Apelin is an endogenous peptide with positive inotropic property secreted by the heart besides other tissues. Plasma apelin levels are altered in chronic heart failure with left ventricular dysfunction. However, the effect of left atrial hemodynamic overload on plasma apelin levels in mitral stenosis (MS) is unknown. In this observational study, we estimated plasma apelin level in M...
B-type natriuretic peptide (BNP) decreases cardiac preload and hypertrophy. As such, synthetic BNP, nesiritide, was approved for the treatment of acutely decompensated heart failure. However, two problems limit its therapeutic potential. First, ensuing hypertension decreases urine output, and second, guanylyl cyclase-A (GC-A), the primary signaling receptor for BNP, is down-regulated in heart f...
The focus on brain natriuretic peptide (BNP) as a biomarker, the elevation of which is associated with adverse outcomes in persons with heart failure, has obscured recognition of the myriad beneficial and compensatory biological actions provided by this small peptide hormone. Both atrial and ventricular cardiomyocytes synthesize and release both atrial natriuretic peptide (ANP) and BNP in respo...
BACKGROUND Congestive heart failure (CHF) is associated with endothelial perturbation (as defined by flow-mediated endothelial-dependent vasodilation [FMD, an index of endothelial dysfunction], circulating endothelial cells [CECs, an index of endothelial damage], or plasma indexes of endothelial damage/dysfunction [eg, von Willebrand factor (vWf) and soluble thrombomodulin (sTM)]) and raised pl...
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 recent guideline from the European Society of Cardiology and European Society of Anesthesiology recommended the use of B-type natriuretic peptide (BNP) as preoperative testing for high-risk cardiac patients undergoing non-cardiac surgery. In this article, the potential benefits, risks and details for implementing BNP testing in perioperative medicine are discussed. Review of four related li...
BACKGROUND Cardiac resynchronization therapy is a modality with proven morbidity and mortality benefit in advanced systolic heart failure. Nevertheless, not all patients respond favorably to CRT. Natriuretic peptides and inflammatory markers are elevated in congestive heart failure and reflect disease severity. OBJECTIVES To test whether an early change in neurohormonal and inflammatory marke...
AIMS Neutrophil gelatinase-associated lipocalin (NGAL) is a measure of acute kidney injury. Renal dysfunction portends significant risk after discharge from acute heart failure (AHF). Thus, a sensitive marker of renal injury might also help to risk stratify HF patients. METHODS AND RESULTS GALLANT [NGAL EvaLuation Along with B-type NaTriuretic Peptide (BNP) in acutely Decompensated Heart Fail...
BACKGROUND Diastolic dysfunction associated with high blood pressure (BP) leads to cardiac remodeling and fibrosis and progression to congestive heart failure. B-type natriuretic peptide (BNP) has BP-lowering, antifibrotic, and antihypertrophic properties, which makes BNP an attractive agent for attenuating the adverse cardiac remodeling associated with hypertension. In the current study, we te...
