OBJECTIVE To investigate the usefulness of measuring plasma concentrations of B type natriuretic peptide in the diagnosis of left ventricular systolic dysfunction in an unselected group of elderly people. DESIGN Observational study. SETTING General practice with four centres in Poole, Dorset. PARTICIPANTS 155 elderly patients aged 70 to 84 years. MAIN OUTCOME MEASURES Diagnostic charact...

Anesthesiology, V 123 • No 2 246 August 2015 T HE heart is not only a pumping organ but also an endocrine organ. B-type natriuretic peptide (BNP) is secreted primarily by cardiac ventricular myocytes in response to increased ventricular wall stress induced by volume expansion, pressure overload, or ischemia.1 BNP protein formation begins with intracellular translation into a large preprohormone...

OBJECTIVE The association between biochemical markers and left ventricular ejection fraction in patients with myocardial infarction was not completely studied. Our goal is to study the association between biochemical markers and left ventricular dysfunction in patients with ST-elevation acute myocardial infarction. METHODS With an observational and prospective design we included patients with...

BACKGROUND Measurement of circulating natriuretic peptides has been shown to play an important role in diagnosis and prognosis in patients with chronic heart failure. Whether serial natriuretic peptide measurements to aid in the titration of therapy can improve heart failure outcomes remains uncertain. We performed a quantitative meta-analysis of available randomized controlled trials to determ...

We thank Drs Chang and Hancox for their interest in our work on natriuretic peptides in community-acquired pneumonia. 1 – 4 The current report 1 extends our previous observations and tries to highlight fi ndings that (1) apply to the whole family of natriuretic peptides in general and (2) provide a direct comparison of the clinical potential of all three commercially available natri uretic pep...

Mammalian natriuretic peptides (NPs) have been extensively investigated for use as therapeutic agents in the treatment of cardiovascular diseases. Here, we describe the isolation, sequencing and tridimensional homology modeling of the first C-type natriuretic peptide isolated from scorpion venom. In addition, its effects on the renal function of rats and on the mRNA expression of natriuretic pe...

Measurement of N-terminal pro-B-type natriuretic peptide has been shown a good rule-out test for cardiac dysfunction in patients in the intensive care unit. The peptide measurement should not be used as a replacement for other forms of monitoring, and performs best as a diagnostic test when interpreted together with other clinical findings and investigations. At a cutoff value similar to that f...

The natriuretic peptide family consists of three endogenous ligands: atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). They exert their biological actions through two subtypes of particulate guanylyl cyclase (GC): GC-A for ANP and BNP, and GC-B for CNP. Among the natriuretic peptide family members, ANP and BNP are cardiac hormones that are ...
