BACKGROUND Natriuretic peptide concentrations in adults require age- and sex-specific reference intervals for optimal interpretation. Females have higher natriuretic peptide concentrations, and hypotheses suggest that estrogen may be responsible. This study sought to determine the influence of hormone modulation on N-terminal probrain natriuretic peptide (NT-proBNP) by using a pediatric cohort....

Background: N-terminal pro brain-type natriuretic peptide (NT-proBNP) is a practical biomarker in the clinical pathologies where ventricle under stress and particularly stretched general population. The study aims to compare value of NT-proBNP its importance prognosis severity cases involving pregnant patients with SARS-CoV-2 infection cardiovascular risk factors those low-risk patients, mainly...

OBJECTIVES The purpose of this work was to assess the effect of percutaneous coronary revascularization (PCR) on plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration. BACKGROUND Left ventricular (LV) dysfunction is associated with increased plasma natriuretic peptide concentrations. The effect of ischemia resolution on plasma natriuretic peptide is not known. METHODS T...

In the clinical researches, large number of clinical verifications has demonstrated that the Brain Natriuretic Peptide can be used in heart failure detection. Some relevant studies illustrate Plasma Brain Natriuretic Peptide can be affected by many factors, such as gender, age, environment of therapy, and so forth. This paper analyzes valid data of a clinical experiment, and finds out the influ...

Deposition of amyloid in the atria (isolated atrial/cardiac amyloid) is fairly common in the aging heart. It consists of amyloid fibrils, formed both by atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) and the precursor molecule of ANP, proANP. This study examines whether amyloidogenic determinants (short peptides/amyloid forming favoring regions) exist in the sequence of NT...

OBJECTIVES We sought to characterize natriuretic peptide levels in a cohort of rigorously characterized subjects with lone atrial fibrillation (AF). BACKGROUND Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are sensitive biomarkers of cardiac contractile dysfunction. Both peptides have been reported to be elevated in cohorts with AF, but previous studies have included su...

OBJECTIVES The purpose of this study was to assess whether management of heart failure (HF) guided by an individualized N-terminal pro-B-type natriuretic peptide (NT-proBNP) target would lead to improved outcome compared with HF management guided by clinical assessment alone. BACKGROUND Natriuretic peptides may be attractive biomarkers to guide management of heart failure (HF) and help select...
