[PMID: 36346821 PMCID: PMC10166265 DOI: 10.1210/endrev/bnac029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 09/13/2022] [Accepted: 11/04/2022] [Indexed: 11/10/2022]
Abstract
Measurement of natriuretic peptides (NPs) has proven its clinical value as biomarker, especially in the context of heart failure (HF). In contrast, a state partial NP deficiency appears integral to several conditions in which lower NP concentrations in plasma presage overt cardiometabolic disease. Here, obesity and type 2 diabetes have attracted considerable attention. Other factors - including age, sex, race, genetics, and diurnal regulation - affect the NP "armory" and may leave some individuals more prone to development of cardiovascular disease. The molecular maturation of NPs has also proven complex with highly variable O-glycosylation within the biosynthetic precursors. The relevance of this regulatory step in post-translational propeptide maturation has recently become recognized in biomarker measurement/interpretation and cardiovascular pathophysiology. An important proportion of people appear to have reduced effective net NP bioactivity in terms of receptor activation and physiological effects. The state of NP deficiency, then, both entails a potential for further biomarker development and could also offer novel pharmacological possibilities. Alleviating the state of NP deficiency before development of overt cardiometabolic disease in selected patients could be a future path for improving precision medicine.

NT-proBNP Concentrations in the Umbilical Cord and Serum of Term Neonates: A Systematic Review and Meta-Analysis. Diagnostics (Basel) 2022; 12:diagnostics12061416. [PMID: 35741227 PMCID: PMC9222102 DOI: 10.3390/diagnostics12061416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 05/29/2022] [Accepted: 06/06/2022] [Indexed: 11/16/2022] Open
Abstract
The detection of NT-proBNP levels both in umbilical cord blood (UCB) samples and in serum samples collected from healthy term neonates during the neonatal period. A systematic review of relevant literature in accordance with PRISMA guidelines was conducted. For quality appraisal, the potential risk of bias was assessed using the BIOCROSS evaluation tool. The random-effects and fixed-effects models were used to calculate weighted mean differences with a corresponding 95% confidence interval. A total of forty (40) studies met the inclusion criteria for the systematic review. After further examination, eighteen (18) studies (1738 participants) from the UCB sample group and fourteen (14) studies (393 participants) from the serum sample group were selected to perform a meta-analysis. Using the fixed-effects model, the mean intervals of NT-proBNP in UCB and serum samples were 492 pg/mL (95% CI: 480−503 pg/mL) and 1341 pg/mL (95% CI: 1286−1397 pg/mL), respectively. A higher concentration of ΝΤ-proBNP was observed in the serum sample group compared to the UCB samples (p < 0.001). We present the intervals of NT-proBNP in UCB and in the serum of healthy term neonates. The determination of the potential effect of perinatal factors on the biomarker’s reference range was also aimed.

Prenatal Particulate Matter (PM) Exposure and Natriuretic Peptides in Newborns from Mexico City. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18126546. [PMID: 34206994 PMCID: PMC8296353 DOI: 10.3390/ijerph18126546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 05/26/2021] [Accepted: 05/27/2021] [Indexed: 11/16/2022]
Abstract
(1) Background: The aim of this study was to assess associations between particulate matter (PM) exposure and natriuretic peptide concentrations in cord blood from newborns. (2) Methods: we conducted a cross-sectional study in Mexico City with 101 pregnant women from CIMIGEN Hospital. Atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) were measured in plasma from cord blood in 51 newborns by ELISA. We estimated PM exposure (PM2.5 and PM10) at first, second and third trimester of pregnancy. (3) Results: The median and interquartile range for ANP, BNP and CNP plasma concentrations were 66.71 (46.92-80.23), 98.23 (73.64-112.30) and 1129.11 (944.10-1452.02) pg/mL, respectively. PM2.5 and PM10 levels for the whole pregnancy period were 22.2 µg/m3 and 41.63 µg/m3, respectively. Employing multivariable linear regression models adjusted for maternal age, newborn sex, smoking before pregnancy, maternal occupation and newborns' length and height, we observed a 2.47 pg/mL (95%CI: -4.67, -0.27) decrease in BNP associated with PM2.5 exposure during second trimester. Adjusted for the same set of confounders, third trimester PM10 exposure was inversely associated with ANP concentrations (beta estimate: -0.90; 95% CI: -1.80, -0.03). Neither PM10 nor PM2.5 were associated with CNP at any trimester of pregnancy. (4) Conclusions: Prenatal exposure to particulate matter was associated with ANP and BNP decrease in newborns.

Abstract
During the last decade, interest in the brain natriuretic peptide (BNP) and N-terminal probrain natriuretic peptide (NT-proBNP) in the pediatric population has progressively increased. The aim of this article is to provide an up to date review of evidences regarding the use of BNP/NT-proBNP in pediatrics, with a particular focus on neonatal intensive care and congenital heart disease. The potentialities of the BNP have been demonstrated in multiple settings, particularly: the screening of congenital/acquired heart disease (CHD) versus pulmonary disease; the evaluation of CHD severity (grade of heart failure, degree of left-to-right shunts); the management of children undergoing cardiac surgery; and monitoring premature infants with patent arterial duct. BNP/NT-proBNP values may be considered an easy and relatively low cost additional diagnostic and prognostic tool. Interpretation of BNP values in children requires attention to important factors, including: laboratory methods, the type of cardiac defect, its severity, and the presence of extracardiac conditions. Of these, the hemodynamic characteristic of CHD and physiologic variations of BNP values occurring during the first weeks of life play a major role. The current evidences in favor of BNP use are mainly derived from single-center, nonrandomized studies, and cost-effectiveness analysis are still lacking. As such, despite sufficient evidences supporting the diagnostic and prognostic potentialities of BNP, these findings should be reinforced by multicenter, randomized studies specifically designed to evaluate outcomes and cost-effectiveness. In addition, standard consensus documents/guidelines, that are currently lacking, are warranted for a more systematic use of BNP in the pediatric age.

Abstract
BACKGROUND Cardiomyopathy is a common finding in offspring of pre-gestational type 1 diabetic pregnancy. Echocardiographic and biochemical evidence of fetal cardiac dysfunction have also been reported. Studies suggest that offspring of diabetic mothers (ODM) undergo a fetal programming effect due to the hyperglycaemic intrauterine milieu which increases their risk of cardiovascular morbidity in adult life. Decreased neonatal heart rate variability (HRV) has been described in association with in-utero growth restriction, prematurity, sudden infant death syndrome and congenital heart disease. The effect of in-utero exposure to hyperglycaemia in diabetic pregnancy on neonatal HRV is unknown. AIMS Our aim was to determine if neonatal HRV differs between normal and diabetic pregnancy. STUDY DESIGN AND SUBJECTS This was a prospective observational study of 38 patients with pregestational type 1 diabetes and 26 controls. HRV assessment was performed using Powerlab (ADI Instruments Ltd). OUTCOME MEASURES Heart rate variability assessment and cord blood sampling for pH and glucose were performed for all neonates. Maternal glycaemic control was assessed via measurement of glycosylated haemoglobin in each trimester in the diabetic cohort. RESULTS Neonates of diabetic mothers had evidence of altered heart rate variability, with increased low frequency to high frequency ratio (LF: HF), suggestive of a shift towards sympathetic predominance (p<0.05). This altered HRV was significantly related to fetal acidaemia, cord blood glucose values and maternal glycaemic control during pregnancy (p<0.05). CONCLUSION Neonates of pregestational diabetic pregnancy have altered HRV which is related to maternal hyperglycaemia, fetal acidaemia and fetal glycaemia. Exposure of the developing heart to fluctuations in maternal glycaemia with subsequent alterations in HRV may explain why infants of diabetic mothers are at greater risk of cardiovascular disease in later life.

Abstract
This study compares NT proBNP and troponin T levels in umbilical cord arterial blood and postnatal echocardiographic findings for infants of gestational and pregestational diabetic mothers and macrosomic infants. Twenty-seven infants of pregestational diabetic mothers, 61 infants of gestational diabetic mothers and 37 macrosomic infants of nondiabetic mothers were prospectively enrolled in this study along with a control group of 58 healthy infants of mothers without any pregestational or gestational disorders as the control group. All enrollees were born after 34 weeks of gestation. For this study, umbilical cord blood was drawn during delivery to determine NT proBNP and troponin T levels. Echocardiography was performed 24-72 h after the delivery. Umbilical cord troponin T and NT proBNP levels were found to be higher in the diabetic and macrosomic groups than in the control group (all of them p < 0.001). NT proBNP levels were positively correlated with interventricular septum thickness in the pregestational and gestational infants of diabetic mothers groups (r = 0.564 and r = 0.560, respectively, p < 0.01). Both pregestational and gestational diabetic mothers were divided into two groups according to HbA1c levels in the third trimester as good (<6.1 %) and suboptimal (>6.1 %) metabolic control. In the good and suboptimal metabolic control diabetic groups, NT proBNP levels were also positively correlated with interventricular septum thickness (r = 0.536 and r = 0.576, respectively, p < 0.01). In the suboptimal metabolic control diabetic group, NT proBNP was only found to be positively correlated with the left ventricular mass index (r = 0.586, p < 0.01). While there was no correlation in the myocardial performance index between infants of diabetic mothers and the control group, the myocardial performance index of macrosomic infants was lower than that of the control group (p = 0.017). Cardiac biomarkers (NT proBNP and troponin T) were elevated in infants of diabetic mothers and macrosomic infants. While there was a positive correlation between NT proBNP levels and cardiac structure in infants of pregestational and gestational diabetic mothers, there was no relationship between NT proBNP levels and cardiac function.

Abstract
INTRODUCTION Since maternal diabetes may affect fetal development and the umbilical cord provides an extension of the fetal vasculature, we decided to investigate cords' biological responses to maternal diabetic milieu. METHODS Using microarray analysis, we determined the gene expression profiles in the umbilical cords of six neonates born to type 1 diabetic mothers and in six control cords. Umbilical cord tissue was collected immediately after elective cesarean section. Expression data were confirmed by real-time polymerase chain reaction (11 genes). Additionally, the same umbilical cords were analyzed histologically. RESULTS Two hundred eighty six genes were differentially expressed in the umbilical cords from diabetic pregnancies compared to the controls (fold change ±1.5 and P < 0.01). Maternal diabetes had a major effect on the expression of genes involved in vascular development (Bone morphogenetic protein 4, Delta-like 1, and Notch homolog 4), vessel wall integrity (Collagen type VIII alpha 1, Myocyte enhancer factor 2C, and Matrix metalloproteinase 2), and vascular function (Natriuretic peptide precursor B, Endothelin 1, Endothelin receptor B, Cyclooxygenase 1, and Phosphodiesterase 5A). Maternal diabetes was associated with thicker umbilical vein intima-media layers and larger umbilical vein and artery intima-media areas compared to the controls. DISCUSSION Maternal diabetic environment seems to alter umbilical cord expression of genes involved in the regulation of vascular development and function with simultaneous umbilical vessel muscle layer thickening. These alterations suggest vascular phenotypic modifications, which in turn may lead to long-term vascular consequences in various tissues in infants of diabetic mothers.

Abstract
Interest in brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in the management of children with CHD has increased. There are, however, no current guidelines for their routine use. The aim of this review article is to provide an update on the data regarding the use of BNP/NT-proBNP in the evaluation and surgical treatment of children with CHD. BNP/NT-proBNP levels in children with CHD vary substantially according to age, laboratory assay methods, and the specific haemodynamics associated with the individual congenital heart lesion. The accuracy of BNP/NT-proBNP as supplemental markers in the integrated screening, diagnosis, management, and follow-up of CHD has been established. In particular, the use of BNP/NT-proBNP as a prognostic indicator in paediatric cardiac surgery has been widely demonstrated, as well as its role in the subsequent follow-up of surgical patients. Most of the data, however, are derived from single-centre retrospective studies using multivariable analysis; prospective, randomised clinical trials designed to evaluate the clinical utility and cost-effectiveness of routine BNP/NT-proBNP use in CHD are lacking. The results of well-designed, prospective clinical trials should assist in formulating guidelines and expert consensus recommendations for its use in patients with CHD. Finally, the use of new point-of-care testing methods that use less invasive sampling techniques - capillary blood specimens - may contribute to a more widespread use of the BNP assay, especially in neonates and infants, as well as contribute to the development of screening programmes for CHD using this biomarker.

Abstract
AIM To examine concentrations of three cardiovascular propeptides in umbilical cord plasma of neonates born to mothers with Type 1, Type 2 and gestational diabetes. Measurement of cardiovascular markers in umbilical cord plasma may potentially help identify neonates at risk of postnatal complications. Neonates born to mothers with diabetes have an increased risk of neonatal morbidity and mortality, and measurement of these new biomarkers may potentially help identify neonates at risk of these complications. SUBJECTS & METHODS Copeptin, midregional proadrenomedullin (MR-proADM) and mid-regional pro-A-type natriuretic peptide (MR-proANP) were measured in cord plasma of neonates (n = 63) born to mothers with the three types of diabetes. Associations with maternal glycemic control, mode of delivery and neonatal metabolic acidosis were examined. RESULTS Umbilical cord plasma copeptin concentrations were lowest in neonates after elective cesarean sections (6.1 pmol/l; interquartile range [IQR]: 4.5-9.1) compared with emergency cesarean sections (156 pmol/l; IQR: 9.6-311; p = 0.019) and vaginal delivery (831 pmol/l; IQR: 107-2407; p < 0.0001). MR-proADM was also affected by mode of delivery; however, this seemed more likely to be caused by an inverse association with the acid-base balance. In this population, only MR-proANP plasma concentrations were related to type of diabetes. Neonates born to mothers with Type 1 diabetes had higher concentrations (median 260 pmol/l; IQR: 222-318) compared with Type 2 diabetes (175 pmol/l; IQR: 169-200; p = 0.003) and gestational diabetes (200 pmol/l; IQR: 149-276; p = 0.009). CONCLUSION Umbilical cord plasma copeptin and MR-proADM concentrations primarily reflect perinatal stress associated with mode of delivery and the degree of fetal acidosis, whereas MR-proANP concentrations are higher in neonates born to mothers with Type 1 diabetes.

Abstract
Plasma measurement of cardiac natriuretic peptides constitutes promising markers of congenital heart disease. However, concentrations change rapidly and dramatically during the first days after delivery even in healthy neonates, which complicates clinical interpretation. It is unknown whether these changes in plasma concentrations are explained by corresponding changes in the cardiac gene expression. We quantified the chamber-specific mRNA levels of ANP (A-type natriuretic peptide) and BNP (B-type natriuretic peptide) and plasma pro-ANP and BNP-32 concentrations in healthy piglets during the first 72 hours of life (from 2 litters, n = 44). Chamber-specific ANP and BNP mRNA levels reflected hemodynamic neonate changes at birth but did not correlate with circulating natriuretic peptide concentrations. However, plasma pro-ANP and creatinine concentrations were closely correlated (P < .0001; r = 0.73). Plasma pro-ANP levels were highest on the day of delivery (5580 pmol/L [4320-6786] decreasing to 2484 pmol/L [1602-2898] after 72 hours, P < .0001). During the 72 hours, gel chromatography suggested that the translational products in circulation and in atrial tissue were immature, ie, unprocessed pro-ANP. In contrast to pro-ANP, BNP-32 plasma concentrations were low at delivery and peaked after 48 hours (12 [10.5-20.6] vs. 88.8 [71.7-101.4] pmol/L, P < .0001). To conclude, ANP and BNP gene expression differs considerably between cardiac chambers in the first 72 hours of life in healthy piglets, resembling the transition from fetal to neonate circulation. However, the cardiac gene expression does not explain plasma concentrations.

Abstract
BACKGROUND Although the B-type natriuretic peptide (BNP) levels in the umbilical cord blood (UCB-BNP) and amniotic fluid (AF-BNP) of neonates may be clinically useful for identifying newborns with cardiac dysfunction, the effects of various clinical factors, such as gestational age at birth, small for gestational age (SGA), and neonatal asphyxia, on the UCB-BNP and AF-BNP levels have not been studied extensively. METHODS The present study sought to determine whether the UCB-BNP and AF-BNP levels can predict cardiac dysfunction and hypotension in preterm infants soon after birth and to evaluate the association between BNP and various clinical factors. The UCB-BNP and AF-BNP levels at birth were determined in 320 and 195 neonates, respectively, born to mothers with singleton pregnancies. RESULTS The UCB-BNP and AF-BNP levels in infants treated with dopamine were significantly higher than those in infants without dopamine administration (230.1 vs 33.1 pg/mL and 74.4 vs 18.1 pg/mL, respectively). Stepwise multiple regression analyses indicated that gestational age, SGA, asphyxia, and chorioamnionitis were significant independent determinants of the UCB-BNP level. Cut-off values of >90 pg/mL for UCB-BNP and >36 pg/mL for AF-BNP yielded sensitivities of 68% and 93%, respectively, and specificities of 84% and 81%, respectively, for detecting neonates who required dopamine administration after birth. CONCLUSION High UCB-BNP and AF-BNP levels predict neonatal cardiac dysfunction soon after birth.

Abstract
The aim of this article is to review the diagnostic and prognostic relevance of measurement of brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in pediatric patients with congenital cardiac diseases (CHD). A computerized literature search in the National Library of Medicine using the keywords "BNP assay" and "NT-proBNP assay"+neonate/s and newborn/s was performed. Next, we refined the analysis to include only the studies specifically designed to evaluate the clinical usefulness of BNP and NT-proBNP measurements in children with CHD. Several authors suggested that BNP/NT-proBNP is clinically helpful as a diagnostic and prognostic marker for children with suspected CHD. BNP values are age dependent, even in paediatric populations. Unfortunately, accurate reference values for BNP and NT-proBNP for neonatal ages have only recently become available. As a result, the lack of homogenous and accurate decisional levels in the neonatal period greatly limits the clinical impact of the BNP assay, and also contributed to the production of conflicting results. Regardless of age, there is great variability in BNP/NT-proBNP values among CHD characterized by different hemodynamic and clinical conditions. In particular, cardiac defects characterized by left ventricular volume and pressure overload usually show a higher BNP response than CHD which is characterized by right ventricular volume or pressure overload. BNP and NT-proBNP may be considered helpful markers in the integral clinical approach for patients with CHD. Measurement of BNP cannot replace cardiac imaging (including echocardiography, angiography and magnetic resonance), but provide independent, low cost and complementary information for the evaluation of cardiac function and clinical status.

Abstract
Pregnancy in women with pregestational diabetes is associated with high perinatal morbidity and mortality. Stillbirth accounts for the majority of cases with perinatal death. Intrauterine growth restriction, pre-eclampsia, foetal hypoxia and congenital malformations may be contributing factors, but more than 50% of stillbirths are unexplained. Majority of stillbirths are characterised by suboptimal glycaemic control during pregnancy. Foetal hypoxia and cardiac dysfunction secondary to poor glycaemic control are probably the most important pathogenic factors in stillbirths among pregnant diabetic women. There is thus a need for new strategies for improving glycaemic control to near-normal levels throughout pregnancy and for preventing and treating hypertensive disorders in pregnancy. Antenatal surveillance tests including ultrasound examinations of the foetal growth rate, kick counting and non-stress testing of foetal cardiac function are widely used. However, future research should establish better antenatal surveillance tests to identify the infants susceptible to stillbirth before it happens.

Abstract
OBJECTIVE Cardiomyopathy is noted in up to 40% of infants of diabetic mothers, and the exact mechanisms are unknown. The aim of this study was to determine whether fetal serum markers of cardiac function differ between normal and type 1 diabetic pregnancies and to examine the relationship between these markers and fetal cardiac structure and function. RESEARCH DESIGN AND METHODS This was a prospective observational study of 45 type 1 diabetic pregnancies and 39 normal pregnancies. All participants had concentrations of fetal pro-B-type natriuretic peptide (proBNP) and troponin-T (TnT) measured at the time of delivery. All patients with type 1 diabetes had Doppler evaluation of the umbilical artery, middle cerebral artery, and ductus venosus in the third trimester, and a subset (n = 21) had detailed fetal echocardiograms performed in each trimester. RESULTS Fetal proBNP and TnT concentrations were higher in the diabetic cohort than in the normal cohort (P < 0.05). ProBNP correlated positively with interventricular septum thickness (P < 0.05) but not with cardiac function indexes in the third trimester. In patients with poor glycemic control, there was a significant positive correlation (P < 0.05) between fetal TnT and the third trimester umbilical artery pulsatility index. There were also increased levels of fetal TnT in infants with poor perinatal outcome (P < 0.05). CONCLUSIONS Biochemical markers of cardiac dysfunction are elevated in infants of diabetic mothers, especially those with cardiomyopathy or poor perinatal outcome. Hyperglycemia in early pregnancy may affect myocardial and placental development, thus contributing to the susceptibility to hypoxia seen in these infants.

Abstract
Maternal diabetes is associated with increased transport of lipids to the fetus and increased risk of hypertrophic cardiomyopathy in the fetus. During fetal life, the heart normally has limited capacity to use lipids as fuel; and, at least in adults, cardiac lipid accumulation may lead to cardiomyopathy. Postnatally, lipid supply is increased when the offspring begins to suckle. We examined offspring from hypoinsulinemic Ins2(Akita) mice to assess whether maternal diabetes results in fetal myocardial hypertrophy and triglyceride accumulation and compared these with fetal hearts collected postnatally. On embryonic days 16 to 19, the fetal heart weight and triglyceride content were similar in offspring from Ins2(Akita) and nondiabetic wild-type mothers. The heart expression of lipid-metabolizing genes (peroxisomal proliferator-activated receptor alpha, lipoprotein lipase, fatty acid translocase, and fatty acid transport protein 1) was reduced in offspring from Ins2(Akita) mothers with high blood glucose levels and were closely intercorrelated, suggesting coordinated down-regulation. In contrast, on day 1 postnatally where the lipid availability to the heart is markedly increased, heart triglycerides and expression of several lipid-metabolizing genes (including lipoprotein lipase and fatty acid transport protein 1) were increased in offspring from wild-type mice. The results suggest that maternal type 1 diabetes mellitus in Ins2(Akita) mice does not cause cardiac hypertrophy or triglycerides accumulation in the fetal heart, possibly because of a coordinated down-regulation of genes controlling fatty acid uptake.

Abstract
BACKGROUND Maternal diabetes increases the risk of hypertrophic cardiomyopathy in the fetus. As signaling via the C-type natriuretic peptide (CNP) specific receptor protects against cardiac hypertrophy, we examined whether maternal type 1 diabetes affects the plasma concentrations of proCNP-derived peptides in newborn infants. METHODS Plasma concentrations of proCNP-derived peptides were measured in umbilical cord plasma and human placental tissue extracts using sequence-specific radioimmunoassays raised against N-terminal and C-terminal proCNP regions, respectively. RESULTS The median proCNP concentrations were similar in umbilical cord plasma from pregnant women with and without type 1 diabetes (17 pmol/L vs. 19 pmol/L, P not significant) and did not correlate with the proBNP concentrations in the same samples. However, the molar ratio between the proCNP and the CNP peptide was increased in umbilical cord plasma compared to adult plasma (4.6 vs. 1.1), which parallels our earlier findings for proBNP and BNP peptides. CONCLUSIONS There is a discordant expression of CNP and BNP peptides in newborn infants of mothers with diabetes. Moreover, fetal metabolism of proCNP and CNP appears to differ from healthy adults. The precise mechanism underlying these differences warrants further investigation.

Abstract
The incidence of heart failure has been steadily increasing over the past several decades. High readmission rates in patients with acute decompensated heart failure led to the search for biomarkers that could predict future clinical course and would, in an ideal case, enable monitoring of patients with heart failure and guidance of their therapy. From among several promising markers, the B-type natriuretic peptide and the biologically inactive N-terminal portion of its pro-hormone, NT-proBNP, have become the most frequently used analytes. Other known markers, such as atrial natriuretic peptide and endothelin-1, are currently used for research purposes. The development of additional biomarkers will be an important step from improving diagnosis and treatment of patients with chronic and acute decompensated heart failure.
