OBJECTIVES Midregional pro-atrial natriuretic peptide (MR-proANP) was assessed for the importance of influencing factors, the ability to detect left ventricular systolic dysfunction, and the prognostic power compared with B-type natriuretic peptide (BNP) and amino-terminal pro-B-type natriuretic peptide (NT-proBNP) in chronic heart failure (HF). BACKGROUND MR-proANP is a biologically stable n...

This study sought to investigate whether the presence of right ventricular systolic dysfunction with pre-existing left ventricular systolic dysfunction is associated with higher plasma brain natriuretic peptide (BNP) levels, compared with patients with isolated left ventricular dysfunction. Eighty-five patients referred for evaluation of isotopic ventricular function were prospectively included...

Editor’s key points † B-type natriuretic peptide (BNP) is a marker of left ventricular systolic dysfunction. † This study confirmed an association between elevated preoperative BNP and perioperative major adverse cardiac events. † The optimum cut-off value for identifying patients at risk of postoperative adverse outcomes remains unclear. Background. The prediction of long-term survival after s...

Background There are scanty data of right ventricular dysfunction markers after major pulmonary resection. Objective To study the changes plasma level N-terminal pro-brain natriuretic peptide (NT-proBNP) and its association with artery pressure (PAP) as in patients who underwent bronchoplastic lobectomy or pneumonectomy. Material Methods The population consisted 36 aged 40–65 resection for lung...

OBJECTIVE To evaluate the role of plasma neurohormones in the diagnosis of asymptomatic or minimally symptomatic right ventricular dysfunction. SETTING Tertiary cardiovascular referral centre. METHODS Plasma brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) concentrations were measured in 21 asymptomatic or minimally symptomatic patients with chronic right ventricular pre...

BACKGROUND AND AIMS Cardiac dysfunction may be present in patients with cirrhosis. This study was undertaken to relate plasma concentrations of cardiac peptides reflecting early ventricular dysfunction (pro-brain natriuretic peptide (proBNP) and brain natriuretic peptide (BNP)) to markers of severity of liver disease, cardiac dysfunction, and hyperdynamic circulation in patients with cirrhosis....

Ventricular concentrations of atrial, brain (BNP) and C-type natriuretic peptide are enhanced in congestive heart failure (CHF). Natriuretic peptide receptors are present on ventricular myocytes and stimulate guanosine 3',5'-cyclic monophosphate (cGMP) production. cGMP has been demonstrated to affect myocyte function in vitro. Thus we hypothesized that the intracardiac natriuretic peptide syste...
