Diagnostic Accuracy of NT-ProBNP for Heart Failure with Sepsis in Patients Younger than 18 Years

This clinical study investigated plasma NT-proBNP levels as a potential predictor of heart failure in pediatric patients with sepsis. Plasma NT-ProBNP levels of 211 pediatric patients with sepsis and 126 healthy children were measured. Patients were stratified as with heart failure (HF) or without heart failure (non-HF). Patients were graded as having sepsis, severe sepsis, or septic shock. The optimal cut-off values of plasma NT-ProBNP for heart failure were determined by analyzing the receiver operating characteristic (ROC). In the HF, non-HF and control groups, the median plasma NT-proBNP levels were 3640, 656, and 226 ng/L, respectively. For all patients with sepsis, the optimal diagnostic cut-off value was 1268 ng/L for differentiating heart failure. In the severe sepsis patients and septic shock patients, the optimal diagnostic cut-off values were 1368 ng/L and 1525 ng/L, respectively. This report is the first one to reveal that NT-proBNP may predict heart failure in children with sepsis. It provides an important clinical reference for the diagnosis of heart failure in pediatric patients with sepsis, and enables monitoring septic children for cardiac involvement.

Clinical effects of an optimised care program with telehealth in heart failure patients in a community hospital in the Netherlands

Background

Our hypothesis was that telehealth in combination with an optimised care program coordinated amongst care professionals in primary, secondary and tertiary care can achieve beneficial outcomes in heart failure. The objective was to evaluate the clinical effects of introduction of telehealth in an optimised care program in a community hospital in the north of the Netherlands.

Methods

We compared the number of unplanned admissions for heart failure in the year before and after adding telehealth to the optimised care program. Furthermore, blood pressure and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were evaluated at baseline and 3, 6 and 12 months after telehealth. Quality of life and knowledge about the disease were regularly evaluated via surveys on the telehealth system.

Findings

The number of unplanned admissions for heart failure decreased from on average 1.29 to 0.31 admissions per year after telehealth introduction. Blood pressure decreased independent of medication and NT-proBNP levels improved as well. Quality of life increased during the telehealth intervention and disease knowledge remained high throughout the follow-up period. Unplanned admissions that remained after telehealth introduction could be accurately predicted at baseline by a multivariate regression model.

Intérêt du dosage des peptides natriurétiques en urgence dans la dyspnée aiguë

Acute dyspnea often leads to an emergency room visit. B-type natriuretic peptide (BNP) and its N-terminal fragment (NT-proBNP) are natriuretic peptide factors secreted by ventricular myocytes when pressure is exerted on the ventricular wall. BNP fights against the activation of the renin-angiotensin-aldosterone system, while NT-proBNP exhibits no activity in this regard. Elevated blood levels of these factors correlate with a variety of functional indices for left-sided heart failure. Several studies have demonstrated their usefulness as markers of left-sided heart failure, the main cause of acute dyspnea seen in emergency rooms. The diagnostic performance of BNP and NT-proBNP appears to be identical; it is, however, greater than that of the emergency room physician. BNP and NT-proBNP have high sensitivity and specificity in the diagnosis of acute heart failure. Briefly, when BNP is less than 100 pg/ml, heart failure is very unlikely (NT-proBNP <500 pg/ml); when it is greater than 400 pg/ml (NT-proBNP >2000 pg/ml); when it is greater than 400 pg/ml (NT-proBNP >2000 pg/ml), it is very likely. The early measurement of BNP in emergency room situations improves the care of patients presenting with acute dyspnea and makes it possible to reduce hospitalisation costs.

目的:探讨急性冠脉综合征(ACS)患者行急诊直接经皮冠状动脉介入治疗(PCI)后住院期间发生心力衰竭(HF)的危险因素分析及护理干预策略。方法:选取278例在我院接受急诊PCI手术患者为研究对象,按照术后住院期间是否出现心力衰竭分为两组:心力衰竭组(n=54例)和非心力衰竭组(n=224例),比较两组患者一般临床资料、实验室检查指标及相关治疗情况的差异,用Logistic回归分析探讨影响术后心力衰竭发生的危险因素,并制定相关护理策略。结果:278例老年患者中有54例PCI术后出现心力衰竭(发生率19.4%);两组患者在年龄、高血压、糖尿病、入院收缩压(SBP)、发病至PCI时间、入院血糖、入院NT-pro BNP、肌酸激酶同工酶(CK-MB)峰值、肌酐蛋白I(c Tn I)峰值、左室射血分数(LVEF)、左室舒张末内径(LVEDd)、术后TIMI血流、使用他汀类药物、β-受体阻滞剂方面存在统计学差异(P0.05);发病至PCI时间、高血压、入院时血糖、NT-pro BNP、c Tn I峰值是术后心力衰竭发生的独立危险因素(P0.05);而术后TIMI血流、使用β-受体阻滞剂治疗是保护性因素。结论:ACS患者行急诊PCI治疗后HF的发生受到多种因素的影响,应当积极制定相关护理干预策略以降低术后HF的发生率。     

Application of determined NT-proBNP in physical standardized exercise

Natriuretic peptides can be used as markers of heart failure, its severity and also in the differential diagnosis of dyspnea. Moreover, the dynamics of natriuretic peptides in physical standardized exercise may be used in the assessment of latent heart failure. AIM OF THE STUDY: Can determination of NT-proBNP be used in the diagnosis of exercise-induced ischemia or latent heart failure? 18 probands (10 men, 8 women) under study were risk persons with unspecified ECG, without signs of manifest heart failure. They were subjected to ergometric bike exercises up to the subjective maximum, SPECT myocardium with estimated ejection fraction of the left ventricle at peak ergometric exercise. The following parameters were followed-up: a) before ergometric exercise: NT-proBNP, CRP, TNF-alpha, Hb, Htc, lactate b) at subjective maximum: NT-proBNP, Hb, Htc, lactate c) 30 min after stopping the exercise: NT-proBNP d) 60 min after stopping the exercise: NT-proBNP. The volume blood changes were taken into account (estimation from the dynamics of Htc, Hb with calculation of metabolic changes of NT-proBNP). To evaluate the dynamics of NT-proBNP, the group was divided into subgroups according to the results obtained in ergometric exercises. RESULTS: initial values of NT-proBNP within normal limits (< 59 pmol/l, 500 ng/l) in 94%, the submaximal pulse rate was reached in 94%, ischemic changes in ECG were observed in 59%, typical clinical signs of heart ischemia were recorded in 35%. Signs of heart dysfunction according to SPECT were found in 47% and ischemic symptoms were observed in 43%. In general, the plasmatic volume decreased by 24% at maximal exercise. Lactate concentration in the plasma increased in all cases. Conversion of NT-proBNP into volume blood changes revealed that increased NT-proBNP occurred only in 22%. Differences between NT-proBNP before exercises and at maximal exercise prior and after correction into volume blood changes were statistically insignificant. 30 and 60 min after the exercise, no significant differences were found in NT-proBNP concentrations. Dividing into subgroups according to the results of ergometric exercises, showed no significant differences in NT-proBNP concentrations. Dynamics of NT-proBNP changes during and after ergometric exercises cannot be used for the diagnosis of exercise-induced heart failure. The high stability of NT-proBNP related to physical activity was confirmed.

The clearance of BNP modeled using the NT-proBNP-BNP relationship

BACKGROUND: The ventricular myocardium simultaneously secretes two natriuretic peptides useful in the evaluation of heart failure: BNP, hormonally active, and NT-proBNP, the N-terminal end, non-hormonally active, but ultimately their concentrations differ and their clearance patterns are poorly defined. METHODS: We measured NT-proBNP and BNP in patients with and without heart failure and compared their concentrations using regression analysis. RESULTS: The relationship between NT-proBNP with BNP is nonlinear. Between 45 and 70 pmol of BNP/L (class II heart failure) the slope is much higher than in other ranges and the NT-proBNP/BNP ratio reaches its maximum in patients with class II NYHA heart failure. CONCLUSIONS: The difference in concentration for NT-proBNP and BNP can be related to the diffusion across the renal basement membrane. Their ratio is nonlinear because BNP is cleared faster than in patients with class II heart failure than other classes or normal, suggesting a change in a non-renal mode of clearance.     

BNP及NT-proBNP与2型糖尿病关系的研究进展

BNP及NT-proBNP是诊断心衰的重要指标。近年来BNP及NT-proBNP与2型糖尿病关系的研究有了新的进展。我们收集近年来国内外关于2型糖尿病中BNP及NT-proBNP的相关文献并进行研究。结果显示2型糖尿病合并冠心病、高血压、糖尿病肾病患者BNP或NT-proBNP有升高趋势。单纯2型糖尿病及糖尿病视网膜病变患者以及低血糖患者BNP或NT-proBNP差异无统计学意义。高血压、年龄、性别、体重指数、肾功能及心脏结构功能改变是2型糖尿病患者BNP及NT-proBNP的影响因素。降糖药物对2型糖尿病患者BNP及NT-proBNP水平的研究尚少,糖尿病病程、FPG以及HbA1c对BNP及NT-proBNP的影响尚存在争议。BNP及NT-proBNP升高对2型糖尿病合并冠心病、高血压、糖尿病肾病患者病情评估,预后判断及诊治具有非常重要的意义。降糖药物、糖尿病病程、FPG以及HbA1c对BNP及NT-proBNP的影响需要进一步研究。

Angiopoietin-2 in Adults with Congenital Heart Disease and Heart Failure

Background

Chronic heart failure is an important cause for morbidity and mortality in adults with congenital heart disease (ACHD). While NT-proBNP is an established biomarker for heart failure of non-congenital origin, its application in ACHD has limitations. The angiogenic factors Angiopoietin-1 and -2 (Ang-1, Ang-2), vascular endothelial growth factor (VEGF), and soluble receptor tyrosine kinase of the Tie family (sTie2) correlate with disease severity in heart failure of non-congenital origin. Their role in ACHD has not been studied.

Methods

In 91 patients Ang-2 and NT-proBNP were measured and related to New York Heart Association class, systemic ventricular function and parameters of cardiopulmonary exercise testing. Ang-1, VEGF, and sTie2 were also measured.

Results

Ang-2 correlates with NYHA class and ventricular dysfunction comparable to NT-proBNP. Further, Ang-2 showed a good correlation with parameters of cardiopulmonary exercise testing. Both, Ang-2 and NT-proBNP identified patients with severely limited cardiopulmonary exercise capacity. Additionally, Ang-2 is elevated in patients with a single ventricle physiology in contrast to NT-proBNP. VEGF, Ang-1, and sTie2 were not correlated with any clinical parameter.

Conclusion

The performance of Ang-2 as a biomarker for heart failure in ACHD is comparable to NT-proBNP. Its significant elevation in patients with single ventricle physiology indicates potential in this patient group and warrants further studies.
