The endocrine role of the heart is evident in the secretion of noradrenaline and natriuretic peptides. The secretion of natriuretic peptides presents a useful mechanism for different conditions of cardiac dysfunction. Brain natriuretic peptide (BNP) has been accepted in human cardiology as a biomarker for cardiac insufficiency and coronary arterial disease. The specificity of the BNP structure is specie-specific, so that the testing of diagnostic and prognostic potential in dogs requires the existence of a test that is a homologue for that animal specie. The existence of an adequate method for measuring BNP concentration makes possible its implementation as a screening test in everyday clinical practice. .

Morbidity And Mortality

Background: Pneumonia in children is a leading cause of morbidity and mortality in developing countries. It is often complicated by Congestive Cardiac Failure (CCF), with some of the symptoms similar to those of pneumonia. Brain Natriuretic Peptide (BNP) assay can differentiate cardiac from respiratory-related causes of respiratory distress. Objective: To determine the role of BNP in differentiating isolated pneumonia from pneumonia complicated by CCF. Methods: Over a 12-month period, consecutive children with radiologically-confirmed pneumonia were recruited for the study. Those with complicating CCF were noted. All the children had blood BNP assay done by ELISA, prior to treatment. Biodata was obtained and the children were grouped into those with isolated pneumonia and those with pneumonia complicated by CCF. Results: Fifty children were recruited; of these 26 (52.0%) had isolated pneumonia while 24 (48.0%) had pneumonia with CCF. The median age of the children was 6 months. The median BNP values for the isolated pneumonia group (229.4 ng/l), was significantly lower than that of pneumonia complicated by CCF group (917.3 ng/l); (p = 0.007). ROC showed that a BNP value >550ng/l could identify children with pneumonia complicated with CCF from those with isolated pneumonia with a sensitivity of 70.4% and specificity of 63.4%. Conclusion: A BNP assay prior to treatment of >550ng/l can differentiate children with pneumonia complicated with CCF from those without CCF.

The purpose of the study was to determine the clinical utility and practical application of preoperative brain natriuretic peptide (BNP) levels. This is a retrospective review of operating room procedures from November 2006 to March 2009. Preoperative history and physical were reviewed and BNP laboratory levels obtained prior to all procedures and the postoperative course reviewed for incidence of 30-day cardiac complications. A receiver operator curve analysis demonstrated that a preoperative BNP threshold ≥95.5 pg/mL correctly identified 75% of patients with cardiac complications and values ≤18.5 pg/mL identified 100% of patients without adverse postoperative cardiac complications. Multivariable analysis also revealed a history of peripheral arterial disease as the most significant preoperative predictor of cardiac complications followed by BNP above the threshold (odds ratio = 3.7), hypothyroidism, coronary artery disease and prior myocardial infarction. In conclusion, preoperative BNP levels are a useful adjunct in clinical practice to help identify those patients with a high postoperative risk and those with a minimal postoperative risk.

Respiratory Causes

Bronchiolitis is a common viral illness which can lead to severe respiratory compromise and can coexist with or mask cardiac failure. Brain natriuretic peptide (BNP) and the inactive portion of its pro-hormone: N-terminal pro-BNP (NT-proBNP) are excreted in response to cardiomyocyte stretching and are established biomarkers in cardiac failure. Here, we discuss the technicalities of NT-proBNP testing and review available evidence regarding NT-proBNP testing in bronchiolitis. We identified and appraised seven studies assessing the role of BNP or NT-proBNP as biomarkers of bronchiolitis severity, in children with and without underlying congenital cardiac disease. One study of 76 children with dyspnoea showed that the median NT-proBNP level in children with cardiac failure was 7321 pg/mL vs 241 pg/mL in children with a respiratory cause of dyspnoea vs 87.21 pg/mL in healthy controls (p<0.05). A cut-off of 726 pg/mL could aid differentiation between cardiac and respiratory causes of respiratory distress. Other evidence showed a positive correlation between BNP levels and bronchiolitis severity, and that raised BNP can predict acute heart failure in children with congenital cardiac disease presenting with bronchiolitis. However, most studies consisted of small cohorts with conflicting evidence between them. Furthermore, several studies assessed BNP rather than NT-proBNP directly. BNP has a shorter half-life, which may affect analysis. In conclusion, NT-proBNP is a rapid and inexpensive test with the potential to be a useful biomarker in severe bronchiolitis and cases complicated by acute cardiac failure. However, studies with larger cohorts are required to better establish this role.

The Relationship

The possibility that natriuretic peptides' effects are important in hypoxia responses of vertebrates is reviewed. Both the transcription and release of natriuretic peptides are affected by oxygen tension. Furthermore, many of the effects observed in hypoxia, such as diuresis and a reduction of plasma volume, are also caused by treatment of the animal with natriuretic peptides. Also, several clinical observations about changes in natriuretic peptide levels in, e.g., sleep apnea and cyanotic congenital heart disease, are consistent with the idea that hypoxia is involved in the etiology of conditions, in which natriuretic peptide levels increase. Virtually all published information on the relationship between oxygen and natriuretic peptides is based on human studies. Because hypoxic conditions are more common in aquatic than terrestrial environments, future studies about the possible role of natriuretic peptides in hypoxia, as well as the role of hypoxia in the evolution of natriuretic peptides, including the different subtypes, should increasingly involve also aquatic organisms.
