Natriuretic Peptide Hormone Measurement in Acute Coronary Syndromes

Cardiac Ischemia is an important trigger for the release of B-type natriuretic peptide (BNP). BNP and N-terminal pro-BNP (N-proBNP) are emerging as important biomarkers for risk stratification in patients with acute coronary syndromes. Higher levels of BNP and pro-BNP are associated with a greater risk for death and heart failure, independent of traditional clinical variables and levels of other biomarkers such as troponins and C-reactive protein. The therapeutic implications of these findings are not yet known.

目的:探讨血浆N末端B型利钠肽原(NT-pro BNP)和心肌肌钙蛋白I(c Tn I)对急性肺栓塞合并右心功能障碍患者病情评估的临床价值。方法:选取急性肺栓塞患者92例,根据超声心动图检查结果将所有患者分为两组:合并右心功能障碍组47例和不合并右心功能障碍组45例。入院后次日即采取空腹静脉血,应用免疫荧光法测定血浆NT-pro BNP和c Tn I水平,并在确诊急性肺栓塞24 h后行超声心动图检查。结果:合并右心功能障碍组血浆NT-pro BNP、c Tn I水平及右心室舒张末期内径均高于不合并右心功能障碍组,两组比较差异均有统计学意义(P均0.01)。受试者工作特征曲线分析发现:NT-pro BNP和c Tn I的曲线下面积均大于90%,最佳阈值分别是554 pg/ml和0.09 ng/ml。Logistic逐步回归分析结果显示:NT-pro BNP(r=1.227,P=0.005)、c Tn I(r=0.862,P=0.016)、右心功能障碍(r=0.936,P=0.008)、心率(r=0.809,P=0.023)与急性肺栓塞患者住院期间预后不良相关。结论:血浆NT-pro BNP和c Tn I水平有助于诊断急性肺栓塞合并右心功能障碍,并能很好地预测近期临床转归。     

Evaluation of N‐Terminal Prohormone B‐Type Natriuretic Peptide in Patients With Acute Coronary Syndromes and Percutaneous Coronary Intervention

J Clin Hypertens (Greenwich). ©2010 Wiley Periodicals, Inc.The aim of this research was to describe N‐terminal part of the prohormone B‐type natriuretic peptide (NT‐proBNP) levels over time in patients with acute coronary syndrome (ACS) before and after percutaneous coronary intervention (PCI). NT‐proBNP, troponin I (Tn‐I), creatine kinase (CK), CK MB isoenzyme (CKMB), fibrinogen, D‐dimers, and C‐reactive protein (CRP) were measured in 300 consecutive patients with ACS before undergoing successful reperfusion with PCI in the first 48 hours, 2 days after, and at the end of the 1st, 3rd, 6th, 12th, 18th, and 24th month. The concentration of NT‐proBNP was cross‐correlated with the levels of NT‐proBNP in 300 patients without ACS and was significantly increased before and after PCI and at the end of the 3rd month, contrasting with the fast conversion to normal levels of Tn‐I, CK, CKMB, fibrinogen, D‐dimers, and CRP. In patients with ACS undergoing successful PCI, NT‐proBNP shows slow kinetics, especially in patients with an increased thrombolysis in myocardial infarction risk score, hypertension, and diabetes. Nevertheless, cardiac neurohormonal activation may be a unifying feature among patients at high risk for cardiovascular events after ACS and PCI. J Clin Hypertens (Greenwich). 2010;12:861–868.

Brain (B‐type) natriuretic peptide (BNP) is a peptide hormone released primarily from the cardiac ventricles in response to myocyte stretch. It is synthesized as an inactive prohormone that is split into the active hormone BNP and the inactive N‐terminal fragment (NT‐proBNP). BNP has a number of systemic effects, including vasodilation, increases in urinary volume and sodium output, and inhibition of the sympathetic nervous system and the renin‐angiotensin‐aldosterone system. ^{1 , 2} Elevated BNP and NT‐proBNP levels may not only reflect increased left ventricular wall stress but may also result directly from cardiac ischemia. ³ The prognostic importance of BNP and NT‐proBNP has been extensively studied in patients with heart failure as well as in patients with acute coronary syndrome (ACS), and both markers have been shown to be strong predictors of morbidity and mortality. ^{4 , 5 , 6} Data from the Framingham Heart Study identified BNP as a strong predictor of morbidity and mortality in the general population even when BNP levels were below the threshold of 100 pg/mL, which is normally used to identify patients with heart failure. ⁷ BNP has been shown to provide valuable prognostic information in patients with ACS. ^{6 , 8 , 9} However, the prognostic importance of natriuretic peptides in patients with acute coronary artery disease (CAD) and percutaneous coronary intervention (PCI) is unclear. Biochemical markers, including troponin I (Tn‐I), ¹⁰ high‐sensitivity C‐reactive protein (CRP), and NT‐proBNP, have become available for the additional evaluation of risk stratification in ACS patients. An association between the level of these biomarkers and the risk of future cardiovascular events has been discussed in patients with ACS. ^{11 , 12 , 13} Therefore, we undertook the present study to evaluate the effect of the level of NT‐proBNP on 24‐month follow‐up and studied the prognostic implications of elevations especially in Tn‐I, NT‐proBNP, and CRP across the spectrum of ACS. A combined prediction for analysis of cardiac events was also carried out to evaluate a multi‐marker strategy for the individualization of risk stratification.     

B型脑钠肽在评估非ST段抬高急性冠脉综合征患者预后中的价值

目的:目前急性冠脉综合征中ST段抬高心肌梗死患者B型脑钠肽水平增高及意义已得到广泛的认同,但对于非ST段抬高心肌梗死(Non-ST elevation myocardial infarction,NSTEMI)和不稳定性心绞痛(Unstable ansina,UA)患者B型脑钠肽的变化及差别尚不肯定.本文通过分析其规律及与近期心血管事件的关系,用于危险分层评估. 方法:入选急性冠脉综合征患者138例,其中NSTEMI组69例,UA组69例,同时人选胸痛就诊但冠状动脉造影正常的患者30例作为对照组.所有患者于发病6小时从周围静脉中留取血样测定B型脑钠肽,同期测定全血肌钙蛋白I.随访3个月内主要不良心血管事件的发生率. 结果:①NSTEMI组、UA组、对照组B型脑钠肽水平分别为54.9 pg/ml(四分位区间为18.20 pg/ml至81.85 pg/ml)、13.9 pg/ml(四分位区间为8.00 ps/ml至26.45 ps/ml和9.4 pg/ml(四分位区间为5.00 pg/ml至12.6 pg/ml),3组之间比较差异有统计学意义,P<0.05.NSTEMI组B型脑钠肽水平最高,并且与全血肌钙蛋白I水平呈正相关(r:0.675,P<0.001).②随访3个月,138例中有30例患者(21.7%)发生主要不良心血管事件,发生者B型脑钠肽水平高于未发生者(31.3 pg/ml vs 19.35 pg/ml),P=0.001. 结论:非ST段抬高急性冠脉综合征患者早期B型脑钠肽水平明显升高,并且B型脑钠肽水平与近期心血管事件的发生有一定相关性,可应用于危险分层的评估.     

Association of Atrial Fibrillation and Amino-terminal Pro-brain Natriuretic Peptide Concentrations in Patients After Off- Pump Coronary Artery Bypass Grafting

Objectives To investigate the possible role of amino-terminal pro-brain natriuretic peptide （NT-proBNP） in the occurrence of atrial fibrillation （AF） after coronary artery bypass grafting （CABG）. Methods This study group included 70 consecutive patients scheduled for elective off-pump CABG. The patients with ejection fraction （EF） less than 0. 30, history of AF, use of class Ⅰ or Ⅲ antiarrhythmic drug, implanted pacemaker, postoperative myocardial infarction or chest reopening for pericardial tamponade were excluded. Preoperative and postoperative serum NT-proBNP levels were measured by radioimmunoassay technique. Results Postoperative AF occurred in 15 patients （21.4%）; these patients had significantly higher median NT-proBNP levels when compared with those without AF after the operation （ P 〈 0. 01 ）. Using multivariate logistic regression analyses, an increase in NT-proBNP level after CABG was found to be independently associated with AF （ OR = 3.78, 95% IC = 1.81 - 4. 89, P 〈 0. 01 ）. Increased age, diabetes mellitus, preoperative use of β-blocker, proximal right coronary artery involvement, and longer operation time were al- so associated with AF. Conclusions These results indicated that AF was associated with higher NT-proBNP concentrations after off pump CABG; the increase in NT-proBNP after CABG may play an important role in the occurrence of AF after the operation. The further studies are needed to define the reason that lead to higher NT-proBNP concentrations among the patients who present AF after off pump CABG.     

B型利钠肽在急性冠脉综合征患者中的临床意义

目的探讨急性冠状动脉综合征（ACS）患者不同危险层次的血浆BNP水平及其与住院期间主要心血管不良事件（MACE）：包括梗死后心绞痛、再梗塞/梗塞延展、严重心律失常、死亡等）的相关性。方法ACS167例,其中不稳定心绞痛（UA）63例,非ST段抬高心肌梗死（NSTEMI）48例,ST段抬高心肌梗死（STEMI）56例,另健康对照组41例。采用酶联免疫吸附（ELISA）法,测定血浆BNP水平。按UA、NSTEMI、STEMI三个危险层次,与有或无心衰两种情况依次分组与对照组比较,并与院内主要不良心血管事件作相关分析。结果血浆BNP水平UA组、NSTEMI组、STEMI组与对照组相比有显著性差异（P=0.0282,P=0.0017,P=0.0000）。且ACS三组之间血浆BNP水平也存在显著性差异（P=0.0363）。剔除心衰病例后,不仅UA组、NSTEMI组、STEMI组与对照组相比仍存在显著性差异（P=0.0342,P=0.0083,P=0.0000）。UA组、NSTEMI组与STEMI组之间差异也仍存在显著性（P=0.0421）。ACS三组中BNP水平,有心衰者显著高于无心衰者（UA组P=0.0411、NSTEMI组P=0.0163、STEMI组P=0.0152）。住院期间BNP水平较高患者中院内MACE发生率也较高（分别为25%vs66.7%）;MACE发生率之间比较有显著性差异（!2=18.13,P=0.0293）。Logistic回归分析校正多变量参数后血浆BNP水平仍与院内MACE独立相关（Wald=10.557,P=0.0042）。结论ACS患者血浆中BNP水平的变化提供了有关心功能不全、心肌缺血与早期危险分层的信息。
