Obesity and nt probnp – ProBNP processing is decreased by obesity in patients with heart failure

In contrast, they had higher concentrations of clearing receptors NPR-C.

One of the most intriguing consequence of the association of natriuretic peptides and obesity is the diagnosis of HFpEF. Increased expression of GalNAc-transferases have been shown to result in increased glycosylation and secretion of proBNP in patients with heart failure 2. These cut-off values were tripled in the presence of atrial fibrillation and adapted to age, but curiously not to BMI. Smoking cessation and weight gain: Evidence from China. Eur Heart J.

  • The association between obesity and low natriuretic peptides is highly relevant in clinical practice for many reasons.

We used the commercially available Roche NT-proBNP 2-site chemiluminescent immunoassay to measure Obesityy in this study as this assay is widely used in heart failure diagnosis and prognosis worldwide. Using antibodies that only detect non-glycosylated proBNP sites, we developed three immunoassays, all of which had ajd common antibody directed towards the C-terminal end of proBNP. The rationale was to rule out many other potential causes of dyspnoea in patients with preserved left ventricular ejection fraction. Based on the existing evidence, specific cut-off values have been established to rule out heart failure depending on the type of presentation, acute or chronic. As detailed in figure 1BNP will act on many different target organs, but its primary effect is dilatation of afferent and constriction of efferent renal arterioles, resulting in increased glomerular filtration and enhanced natriuresis and diuresis. Therefore, it would be ideal to rely on a biomarker in these patients. Thus, leptin and BNP have opposite effects.
