Novel Biomarkers and Their Role in the Diagnosis and Prognosis of Acute Coronary Syndrome. Life (Basel) 2023; 13:1992. [PMID: 37895374 PMCID: PMC10608753 DOI: 10.3390/life13101992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/23/2023] [Accepted: 09/28/2023] [Indexed: 10/29/2023] Open
Abstract
The burden of cardiovascular diseases and the critical role of acute coronary syndrome (ACS) in their progression underscore the need for effective diagnostic and prognostic tools. Biomarkers have emerged as crucial instruments for ACS diagnosis, risk stratification, and prognosis assessment. Among these, high-sensitivity troponin (hs-cTn) has revolutionized ACS diagnosis due to its superior sensitivity and negative predictive value. However, challenges regarding specificity, standardization, and interpretation persist. Beyond troponins, various biomarkers reflecting myocardial injury, neurohormonal activation, inflammation, thrombosis, and other pathways are being explored to refine ACS management. This review article comprehensively explores the landscape of clinically used biomarkers intricately involved in the pathophysiology, diagnosis, and prognosis of ACS (i.e., troponins, creatine kinase MB (CK-MB), B-type natriuretic peptides (BNP), copeptin, C-reactive protein (CRP), interleukin-6 (IL-6), d-dimers, fibrinogen), especially focusing on the prognostic role of natriuretic peptides and of inflammatory indices. Research data on novel biomarkers (i.e., endocan, galectin, soluble suppression of tumorigenicity (sST2), microRNAs (miRNAs), soluble oxidized low-density lipoprotein receptor-1 (sLOX-1), F2 isoprostanes, and growth differentiation factor 15 (GDF-15)) are further analyzed, aiming to shed light on the multiplicity of pathophysiologic mechanisms implicated in the evolution of ACS. By elucidating the complex interplay of these biomarkers in ACS pathophysiology, diagnosis, and outcomes, this review aims to enhance our understanding of the evolving trajectory and advancements in ACS management. However, further research is necessary to establish the clinical utility and integration of these biomarkers into routine practice to improve patient outcomes.

The joint association of diabetes status and NT-ProBNP with adverse cardiac outcomes in patients with non-ST-segment elevation acute coronary syndrome: a prospective cohort study.

Abstract
AIMS To examine the joint association of diabetes status and N-terminal pro-B-type natriuretic peptide (NT-proBNP) with subsequent risk of major adverse cardio-cerebral events (MACCEs) and all-cause mortality in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). METHODS A total of 7956 NSTE-ACS patients recruited from the Cardiovascular Center Beijing Friendship Hospital Database Bank were included in this cohort study. Patients were divided into nine groups according to diabetes status (normoglycemia, prediabetes, diabetes) and NT-proBNP tertiles (< 92 pg/ml, 92-335 pg/ml, ≥ 336 pg/ml). Multivariable Cox proportional hazards models were used to estimate the individual and joint association of diabetes status and NT-proBNP with the risk of MACCEs and all-cause mortality. RESULTS During 20,257.9 person-years of follow-up, 1070 MACCEs were documented. In the fully adjusted model, diabetes and a higher level of NT-proBNP were independently associated with MACCEs risk (HR 1.42, 95% CI: 1.20-1.68; HR 1.72, 95% CI: 1.40-2.11) and all-cause mortality (HR 1.37, 95% CI: 1.05-1.78; HR 2.80, 95% CI: 1.89-4.17). Compared with patients with normoglycemia and NT-proBNP < 92 pg/ml, the strongest numerical adjusted hazards for MACCEs and all-cause mortality were observed in patients with diabetes and NT-proBNP ≥ 336 pg/ml (HR 2.67, 95% CI: 1.83-3.89; HR 2.98, 95% CI: 1.48-6.00). The association between MACCEs and all-cause mortality with various combinations of NT-proBNP level, HbA1c, and fasting plasma glucose was studied. CONCLUSIONS Diabetes status and elevated NT-proBNP were independently and jointly associated with MACCEs and all-cause mortality in patients with NSTE-ACS.

Abstract
PURPOSE OF REVIEW Cardiac troponin (cTn) plays an essential role for assessment of outcome in acute coronary syndrome (ACS). However, the prognostic value of cTn is not absolute. In this mini-review, we summarize the evidence on the utility of established biomarkers of left-ventricular dysfunction, hemodynamic stress, inflammation, and renal dysfunction for risk prediction beyond cTn in ACS. RECENT FINDINGS Only few biomarkers consistently demonstrate additive prognostic value to cTn levels. The B-type natriuretic peptides (NPs) and growth-differentiation factor-15 (GDF-15) are most promising in this regard. However, there are uncertainties regarding the role of these biomarkers for guidance of treatment decisions, and their prognostic increment to cTn levels measured with high-sensitivity assays is largely unknown. The NPs and GDF-15 provide the strongest prognostic increment to cTn levels in ACS. However, the role of these biomarkers for clinical decision-making in contemporary settings has still to be defined.

Abstract
BACKGROUND The benefit of statin therapy in patients with higher grades of heart failure has yet to be determined. The present study investigated whether statin therapy affects major composite outcomes (MCOs) and all-cause mortality in patients with acute myocardial infarction (AMI) within 1 year after AMI, according to their plasma natriuretic peptide (NP) levels and left ventricular ejection fraction (LVEF). METHODS A total of 11,492 patients with AMI from two nationwide registry databases in Korea were analyzed. AMI patients were divided into quartiles by plasma levels of B-type NP (BNP) or N-terminal pro-BNP (NT-proBNP) at admission. Patients with LVEF <40% on initial echocardiography were also evaluated. Total mortality and MCOs within 12 months of AMI, including death, nonfatal MI, and revascularization, were assessed. RESULTS Among AMI patients, statin therapy was included in the discharge medications for 9075 (79.0%) patients, but not for the remaining 2417 patients (21.0%), and statin therapy was associated with a 27.8% lower risk of MCOs. After adjusting for risk factors, statin therapy was associated with lower hazard ratios for MCOs and all-cause mortality in only the third and fourth NP quartile subgroups, being effective only with moderate- to high-intensity statin therapy. However, statins did not modify the outcomes in patients with LVEF <40%. CONCLUSIONS Our results show that moderate- to high-intensity statin therapy was associated with a lower risk of major clinical outcomes and all-cause mortality in AMI patients with higher plasma NP, but not in AMI patients with decreased LVEF.

Can J Cardiol 2017; 33:1478-1488.

Abstract
BACKGROUND Increased N-terminal pro b-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) can identify patients with heart failure (HF) who are at increased risk of cardiac events. The relationship of these biomarkers to the extent of hibernating myocardium and scar has not been previously characterized in patients with ischemic left ventricular dysfunction and HF. METHODS Patients with ischemic HF meeting recruitment criteria and undergoing perfusion and fluorodeoxyglucose-positron emission tomography to define myocardial hibernation and scar were included in the study. A total of 39 patients (mean age 67 ± 8 years) with New York Heart Association class II-IV HF and ischemic cardiomyopathy (ejection fraction [EF], 27.9% ± 8.5%) were enrolled in the study. RESULTS Serum NT-proBNP and hs-cTnT levels were elevated in patients with ≥ 10% hibernating myocardium compared with those with < 10% (NT-pro-BNP, 7419.10 ± 7169.5 pg/mL vs 2894.6 ± 2967.4 pg/mL; hs-cTnT, 789.3 ± 1835.3 pg/mL vs 44.8 ± 78.9 pg/mL; P < 0.05). The overall receiver operating characteristic under the curve value for NT-proBNP and hs-cTnT to predict hibernating myocardium was 0.76 and 0.78, respectively (P < 0.05). The NT-proBNP (P = 0.02) and hs-cTnT (P < 0.0001) levels also correlated with hibernation, particularly in patients with ≥ 10% scar, independent of EF, age, and estimated glomerular filtration rate. No differences were noted in biomarker levels for patients with vs those without ≥ 10% scar. CONCLUSIONS NT-proBNP and hs-cTnT levels are elevated in patients with ischemic HF hibernation and are correlated with the degree of hibernation but not with the presence or extent of scar. Taken together, these data support the novel concept that NT-proBNP and hs-cTnT release in patients with ischemic HF reflects the presence and extent of hibernating myocardium.

Abstract
Abstract
BACKGROUND
Risk stratification in non–ST-elevation acute coronary syndrome (NSTE-ACS) is currently mainly based on clinical characteristics. With routine invasive management, angiography findings and biomarkers are available and may improve prognostication. We aimed to assess if adding biomarkers [high-sensitivity cardiac troponin T (cTnT-hs), N-terminal probrain-type natriuretic peptide (NT-proBNP), growth differentiation factor 15 (GDF-15)] and extent of coronary artery disease (CAD) might improve prognostication in revascularized patients with NSTE-ACS.
METHODS
In the PLATO (Platelet Inhibition and Patient Outcomes) trial, 5174 NSTE-ACS patients underwent initial angiography and revascularization and had cTnT-hs, NT-proBNP, and GDF-15 measured. Cox models were developed adding extent of CAD and biomarker levels to established clinical risk variables for the composite of cardiovascular death (CVD)/spontaneous myocardial infarction (MI), and CVD alone. Models were compared using c-statistic and net reclassification improvement (NRI).
RESULTS
For the composite end point and CVD, prognostication improved when adding extent of CAD, NT-proBNP, and GDF-15 to clinical variables (c-statistic 0.685 and 0.805, respectively, for full model vs 0.649 and 0.760 for clinical model). cTnT-hs did not contribute to prognostication. In the full model (clinical variables, extent of CAD, all biomarkers), hazard ratios (95% CI) per standard deviation increase were for cTnT-hs 0.93(0.81–1.05), NT-proBNP 1.32(1.13–1.53), GDF-15 1.20(1.07–1.36) for the composite end point, driven by prediction of CVD by NT-proBNP and GDF-15. For spontaneous MI, there was an association with NT-proBNP or GDF-15, but not with cTnT-hs.
CONCLUSIONS
In revascularized patients with NSTE-ACS, the extent of CAD and concentrations of NT-proBNP and GDF-15 independently improve prognostication of CVD/spontaneous MI and CVD alone. This information may be useful for selection of patients who might benefit from more intense and/or prolonged antithrombotic treatment. ClinicalTrials.gov Identifier: NCT00391872

Abstract
Acute coronary syndrome (ACS) encompasses a pathophysiological spectrum of cardiovascular diseases, all of which have significant morbidity and mortality. ACS was once considered an acute condition; however, new treatment strategies and improvements in biomarker assays have led to ACS being an acute and chronic disease. Cardiac troponin is the preferred biomarker for the diagnosis of myocardial infarction, and there is considerable interest and efforts toward development and implementation of high-sensitivity cardiac troponin (hs-cTn) assays worldwide. Analytical and clinical performance characteristics of hs-cTn assays as well as testing limitations are important for laboratorians and clinicians to understand in order to utilize testing appropriately. Furthermore, expanding the clinical utility of hs-cTn into other cohorts such as asymptomatic community dwelling populations, heart failure, and chronic kidney disease populations supports novel opportunities for improved short- and long-term prognosis.

Abstract
BACKGROUND Heart failure is a condition in which the heart does not pump enough blood to meet all the needs of the body. Symptoms of heart failure include breathlessness, fatigue and fluid retention. Outcomes for patients with heart failure are highly variable; however on average, these patients have a poor prognosis. Prognosis can be improved with early diagnosis and appropriate use of medical treatment, use of devices and transplantation. Patients with heart failure are high users of healthcare resources, not only due to drug and device treatments, but due to high costs of hospitalisation care. B-type natriuretic peptide levels are already used as biomarkers for diagnosis and prognosis of heart failure, but could offer to clinicians a possible tool to guide drug treatment. This could optimise drug management in heart failure patients whilst allaying concerns over potential side effects due to drug intolerance. OBJECTIVES To assess whether treatment guided by serial BNP or NT-proBNP (collectively referred to as NP) monitoring improves outcomes compared with treatment guided by clinical assessment alone. SEARCH METHODS Searches were conducted up to 15 March 2016 in the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library; MEDLINE (OVID), Embase (OVID), the Database of Abstracts of Reviews of Effects (DARE) and the NHS Economic Evaluation Database in the Cochrane Library. Searches were also conducted in the Science Citation Index Expanded, the Conference Proceedings Citation Index on Web of Science (Thomson Reuters), World Health Organization International Clinical Trials Registry and ClinicalTrials.gov. We applied no date or language restrictions. SELECTION CRITERIA We included randomised controlled trials of NP-guided treatment of heart failure versus treatment guided by clinical assessment alone with no restriction on follow-up. Adults treated for heart failure, in both in-hospital and out-of-hospital settings, and trials reporting a clinical outcome were included. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for inclusion, extracted data and evaluated risk of bias. Risk ratios (RR) were calculated for dichotomous data, and pooled mean differences (MD) (with 95% confidence intervals (CI)) were calculated for continuous data. We contacted trial authors to obtain missing data. Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, we assessed the quality of the evidence and GRADE profiler (GRADEPRO) was used to import data from Review Manager to create a 'Summary of findings' table. MAIN RESULTS We included 18 randomised controlled trials with 3660 participants (range of mean age: 57 to 80 years) comparing NP-guided treatment with clinical assessment alone. The evidence for all-cause mortality using NP-guided treatment showed uncertainty (RR 0.87, 95% CI 0.76 to 1.01; patients = 3169; studies = 15; low quality of the evidence), and for heart failure mortality (RR 0.84, 95% CI 0.54 to 1.30; patients = 853; studies = 6; low quality of evidence).The evidence suggested heart failure admission was reduced by NP-guided treatment (38% versus 26%, RR 0.70, 95% CI 0.61 to 0.80; patients = 1928; studies = 10; low quality of evidence), but the evidence showed uncertainty for all-cause admission (57% versus 53%, RR 0.93, 95% CI 0.84 to 1.03; patients = 1142; studies = 6; low quality of evidence).Six studies reported on adverse events, however the results could not be pooled (patients = 1144; low quality of evidence). Only four studies provided cost of treatment results, three of these studies reported a lower cost for NP-guided treatment, whilst one reported a higher cost (results were not pooled; patients = 931, low quality of evidence). The evidence showed uncertainty for quality of life data (MD -0.03, 95% CI -1.18 to 1.13; patients = 1812; studies = 8; very low quality of evidence).We completed a 'Risk of bias' assessment for all studies. The impact of risk of bias from lack of blinding of outcome assessment and high attrition levels was examined by restricting analyses to only low 'Risk of bias' studies. AUTHORS' CONCLUSIONS In patients with heart failure low-quality evidence showed a reduction in heart failure admission with NP-guided treatment while low-quality evidence showed uncertainty in the effect of NP-guided treatment for all-cause mortality, heart failure mortality, and all-cause admission. Uncertainty in the effect was further shown by very low-quality evidence for patient's quality of life. The evidence for adverse events and cost of treatment was low quality and we were unable to pool results.

Abstract
Plasma B-type natriuretic peptide (BNP) levels were obtained from 146 patients with unstable angina pectoris, non—ST-segment elevation myocardial infarction (MI), or ST-segment elevation MI to determine their value in predicting the presence of new heart failure, recurrent MI or ischemia, or death 1 month after the index event. Patients with elevated plasma BNP levels (>80 pg/mL) had a significantly higher incidence of new heart failure and all-cause mortality than those with a normal plasma BNP level (≤80 pg/mL). Early revascularization with percutaneous intervention or coronary artery bypass grafting significantly reduced the incidence of new heart failure and all-cause mortality in patients with an elevated plasma BNP level, but had no effect on individual outcomes in the normal plasma BNP subgroup.

Abstract
BACKGROUND People with unstable angina and non-ST elevation myocardial infarction (UA/NSTEMI) are managed with a combination of medical therapy, invasive angiography and revascularisation. Specifically, two approaches have evolved: either a 'routine invasive' strategy whereby all patients undergo coronary angiography shortly after admission and, if indicated, coronary revascularisation; or a 'selective invasive' (also referred to as 'conservative') strategy in which medical therapy alone is used initially, with a selection of patients for angiography based upon evidence of persistent myocardial ischaemia. Uncertainty exists as to which strategy provides the best outcomes for these patients. This Cochrane review is an update of a Cochrane review originally published in 2006, to provide a robust comparison of these two strategies in the early management of patients with UA/NSTEMI. OBJECTIVES To determine the benefits and harms associated with the following.1. A routine invasive versus a conservative or 'selective invasive' strategy for the management of UA/NSTEMI in the stent era.2. A routine invasive strategy with and without glycoprotein IIb/IIIa receptor antagonists versus a conservative strategy for the management of UA/NSTEMI in the stent era. SEARCH METHODS We searched the following databases and additional resources up to 25 August 2015: the Cochrane Central Register of Controlled Trials (CENTRAL) on the Cochrane Library, MEDLINE and EMBASE, with no language restrictions. SELECTION CRITERIA We included prospective randomised controlled trials (RCTs) that compared invasive with conservative or 'selective invasive' strategies in participants with acute UA/NSTEMI. DATA COLLECTION AND ANALYSIS Two review authors screened the records and extracted data in duplicate. Using intention-to-treat analysis with random-effects models, we calculated summary estimates of the risk ratio (RR) with 95% confidence intervals (CIs) for the primary endpoints of all-cause death, fatal and non-fatal myocardial infarction (MI), combined all-cause death or non-fatal MI, refractory angina and re-hospitalisation. We performed further analysis of included studies based on whether glycoprotein IIb/IIIa receptor antagonists were used routinely. We assessed the heterogeneity of included trials using Pearson χ² (Chi² test) and variance (I² statistic) analysis. Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, we assessed the quality of the evidence and the GRADE profiler (GRADEPRO) was used to import data from Review Manager 5.3 (Review Manager) to create Summary of findings (SoF) tables. MAIN RESULTS Eight RCTs with a total of 8915 participants (4545 invasive strategies, 4370 conservative strategies) were eligible for inclusion. We included three new studies and 1099 additional participants in this review update. In the all-study analysis, evidence did not show appreciable risk reductions in all-cause mortality (RR 0.87, 95% CI 0.64 to 1.18; eight studies, 8915 participants; low quality evidence) and death or non-fatal MI (RR 0.93, 95% CI 0.71 to 1.2; seven studies, 7715 participants; low quality evidence) with invasive strategies compared to conservative (selective invasive) strategies at six to 12 months follow-up. There was appreciable risk reduction in MI (RR 0.79, 95% CI 0.63 to 1.00; eight studies, 8915 participants; moderate quality evidence), refractory angina (RR 0.64, 95% CI 0.52 to 0.79; five studies, 8287 participants; moderate quality evidence) and re-hospitalisation (RR 0.77, 95% CI 0.63 to 0.94; six studies, 6921 participants; moderate quality evidence) with routine invasive strategies compared to conservative (selective invasive) strategies also at six to 12 months follow-up.Evidence also showed increased risks in bleeding (RR 1.73, 95% CI 1.30 to 2.31; six studies, 7584 participants; moderate quality evidence) and procedure-related MI (RR 1.87, 95% CI 1.47 to 2.37; five studies, 6380 participants; moderate quality evidence) with routine invasive strategies compared to conservative (selective invasive) strategies.The low quality evidence were as a result of serious risk of bias and imprecision in the estimate of effect while moderate quality evidence was only due to serious risk of bias. AUTHORS' CONCLUSIONS In the all-study analysis, the evidence failed to show appreciable benefit with routine invasive strategies for unstable angina and non-ST elevation MI compared to conservative strategies in all-cause mortality and death or non-fatal MI at six to 12 months. There was evidence of risk reduction in MI, refractory angina and re-hospitalisation with routine invasive strategies compared to conservative (selective invasive) strategies at six to 12 months follow-up. However, routine invasive strategies were associated with a relatively high risk (almost double the risk) of procedure-related MI, and increased risk of bleeding complications. This systematic analysis of published RCTs supports the conclusion that, in patients with UA/NSTEMI, a selectively invasive (conservative) strategy based on clinical risk for recurrent events is the preferred management strategy.

Abstract
Background BNP has been extensively evaluated to determine short- and intermediate-term
prognosis in patients with acute coronary syndrome, but its role in
long-term mortality is not known. Objective To determine the very long-term prognostic role of B-type natriuretic peptide
(BNP) for all-cause mortality in patients with non-ST segment elevation
acute coronary syndrome (NSTEACS). Methods A cohort of 224 consecutive patients with NSTEACS, prospectively seen in the
Emergency Department, had BNP measured on arrival to establish prognosis,
and underwent a median 9.34-year follow-up for all-cause mortality. Results Unstable angina was diagnosed in 52.2%, and non-ST segment elevation
myocardial infarction, in 47.8%. Median admission BNP was 81.9 pg/mL (IQ
range = 22.2; 225) and mortality rate was correlated with increasing BNP
quartiles: 14.3; 16.1; 48.2; and 73.2% (p < 0.0001). ROC curve disclosed
100 pg/mL as the best BNP cut-off value for mortality prediction (area under
the curve = 0.789, 95% CI= 0.723-0.854), being a strong predictor of late
mortality: BNP < 100 = 17.3% vs. BNP ≥ 100 = 65.0%, RR = 3.76 (95%
CI = 2.49-5.63, p < 0.001). On logistic regression analysis, age >72
years (OR = 3.79, 95% CI = 1.62-8.86, p = 0.002), BNP ≥ 100 pg/mL (OR
= 6.24, 95% CI = 2.95-13.23, p < 0.001) and estimated glomerular
filtration rate (OR = 0.98, 95% CI = 0.97-0.99, p = 0.049) were independent
late-mortality predictors. Conclusions BNP measured at hospital admission in patients with NSTEACS is a strong,
independent predictor of very long-term all-cause mortality. This study
allows raising the hypothesis that BNP should be measured in all patients
with NSTEACS at the index event for long-term risk stratification.

Abstract
The role of endothelium in the progression of atheromasic disease has already been demonstrated. Endothelin-1 (ET-1) is released from endothelial cells during acute and chronic vascular damage and it appears to be the strongest vasoconstrictor agent known.The aim of this study is to investigate the amount of endothelial damage in patients with unstable angina (UA), as defined by serum levels of ET-1, to verify a possible correlation with increased ischaemic damage by evaluation of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and interleukin 8 (IL-8) levels.Serum levels of ET-1, IL-8 and NT-proBNP obtained from 10 patients affected by low-risk UA were compared to those belonging to eight healthy subjects. In order to compare the laboratory data pertaining to the two populations, a Student's t-test and a Mann-Whitney U test were performed.Levels of ET-1, IL-8 and NT-proBNP in samples of peripheral blood of patients affected by UA were significantly elevated, compared with those of the control group. The linear correlation analysis demonstrated a positive and significant correlation between levels of ET-1 and IL-8, between levels of ET-1 and NT-proBNP, and between levels of IL-8 and NT-proBNP in subjects affected by UA.Early elevated levels of ET-1, IL-8 and NT-proBNP in patients with UA show a coexistence between ischaemic insults and endothelial damages. A positive and significant linear correlation between levels of ET-1 and IL-8, between levels of ET-1 and NT-proBNP, and between levels of IL-8 and NT-proBNP confirms that an increased ischaemic insult is correlated to inflammation signs and endothelium damage signs.In patients with UA, ischaemia is always associated with a systemic immuno-mediated activity induced by acute endothelial damage. We suggest early administration of ET-1-selective receptor blockers and anti-inflammatory drugs.

Abstract
The clinical significance and economic impact of coronary artery disease has triggered major research efforts into the discovery of novel biomarkers for risk stratification in primary and secondary prevention and then the development of assays suitable for routine measurement. Nevertheless, the clinical impact of these novel biomarkers for risk stratification is still limited because they do not add substantially to traditional risk factors and they only modestly-even with a multimarker approach-improve risk stratification and patient reclassification. The most useful markers appear to be high-sensitivity C-reactive protein, natriuretic peptides, and, eventually, high-sensitivity cardiac troponins. Further research is clearly needed.

Abstract
Congestive heart failure is a leading cause of morbidity and mortality throughout the world and is now the leading cause of hospitalizations in adults over 65 years of age with an estimated annual expenditure in excess of USD 20 billion. In addition, it is the only cardiovascular disorder that continues to increase in both incidence and prevalence, and as the population continues to age, it is expected that the prevalence of this disease will continue to rise. Ironically, the armamentarium of medications that decrease mortality due to congestive heart failure also continues to grow; however, the relative number of eligible patients with congestive heart failure (or at risk for congestive heart failure) that receive these important therapies remains low. Thus, better tools to aid the early diagnosis and management of this disease are needed. Testing for natriuretic peptide markers, such as B-type natriuretic peptide or its amino-terminal fragment, has emerged as an important tool to assist in the optimal diagnosis and risk stratification of patients with congestive heart failure and may also play a valuable role in guiding therapy.

Abstract
There is a substantial need for a diagnostic tool to aid in the early diagnosis of heart failure and in the recognition of those at risk for its development, as well as in guidance of therapy. Testing for amino-terminal pro-brain natriuretic peptide (NT-proBNP) has been recognized to have utility in the diagnosis, prognosis and management of heart failure. In addition, numerous other applications for NT-proBNP testing are now recognized, such as evaluation of patients with heart disease in the absence of heart failure, as well as the diagnostic and prognostic evaluation of patients with acute coronary syndromes or pulmonary thromboembolism.

Abstract
BACKGROUND The purpose of the Occluded Artery Trial (OAT) Biomarker substudy was to evaluate the impact of infarct related artery (IRA) revascularization on serial levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and dynamics of other biomarkers related to left ventricular remodeling, fibrosis and angiogenesis. METHODS Patients were eligible for OAT-Biomarker based on the main OAT criteria. Of 70 patients (age 60.8 ± 8.8, 25% women) enrolled in the substudy, 37 were randomized to percutaneous coronary intervention (PCI) and 33 to optimal medical therapy alone. Baseline serum samples were obtained prior to OAT randomization with follow up samples taken at one year. The primary outcome was percent change of NT-proBNP from baseline to 1 year. The secondary outcomes were respective changes of matrix metalloproteinases (MMP) 2 and 9, tissue inhibitor of matrix metalloproteinase 2 (TIMP-2), Vascular Endothelial Growth Factor (VEGF), and Galectin-3. RESULTS Paired (baseline and one-year) serum samples were obtained in 62 subjects. Baseline median NT-proBNP level was 944.8 (455.3, 1533) ng/L and decreased by 69% during follow-up (p < 0.0001). Baseline MMP-2 and TIMP-2 levels increased significantly from baseline to follow-up (p = 0.034, and p = 0.027 respectively), while MMP-9 level decreased from baseline (p = 0.038). Levels of VEGF and Galectin-3 remained stable at one year (p = NS for both). No impact of IRA revascularization on any biomarker dynamics were noted. CONCLUSIONS There were significant changes in measured biomarkers related to LV remodeling, stress, and fibrosis following MI between 0 and 12 month. Establishing infarct vessel patency utilizing stenting 24 hours-28 days post MI did not however influence the biomarkers' release.

Abstract
BACKGROUND Patients with increased blood concentrations of natriuretic peptides (NPs) have poor cardiovascular outcomes after myocardial infarction (MI). The objectives of this analysis were to evaluate the utilization and the prognostic value of NP in a large, real-world MI cohort. METHODS Data from 41 683 patients with non-ST-segment elevation MI (NSTEMI) and 27 860 patients with ST-segment elevation MI (STEMI) at 309 US hospitals were collected as part of the ACTION Registry®-GWTG™ (Acute Coronary Treatment and Intervention Outcomes Network Registry-Get with the Guidelines) (AR-G) between July 2008 and September 2009. RESULTS B-type natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP) was measured in 19 528 (47%) of NSTEMI and 9220 (33%) of STEMI patients. Patients in whom NPs were measured were older and had more comorbidities, including prior heart failure or MI. There was a stepwise increase in the risk of in-hospital mortality with increasing BNP quartiles for both NSTEMI (1.3% vs 3.2% vs 5.8% vs 11.1%) and STEMI (1.9% vs 3.9% vs 8.2% vs 17.9%). The addition of BNP to the AR-G clinical model improved the C statistic from 0.796 to 0.807 (P < 0.001) for NSTEMI and from 0.848 to 0.855 (P = 0.003) for STEMI. The relationship between NPs and mortality was similar in patients without a history of heart failure or cardiogenic shock on presentation and in patients with preserved left ventricular function. CONCLUSIONS NPs are measured in almost 50% of patients in the US admitted with MI and appear to be used in patients with more comorbidities. Higher NP concentrations were strongly and independently associated with in-hospital mortality in the almost 30 000 patients in whom NPs were assessed, including patients without heart failure.

Abstract
BACKGROUND Data on the correlations between biomarkers to suggest cost-effective multi-marker (MM) panels predictive for ST-elevation myocardial infarction (STEMI) patients are lacking. We sought to explore the relationship between cardiac troponin I (cTnI), C-reactive protein (CRP), B-type natriuretic peptide (BNP), and chromogranin A (CgA) accounting for biomarkers' profiles detected within 48h from successful primary percutaneous coronary intervention (PPCI). METHODS In 73 STEMI patients cTnI, CRP, BNP, and CgA were measured before PPCI and 6, 24, and 48h later. STATIS methods generalizing Principal Component Analysis on three-way data sets were employed to extract information about: 1) similarities between patients, 2) contribution of each time of sampling and 3) correlations between biomarkers' profiles. RESULTS STEMI patients who underwent successful PPCI emerged to have a homogeneous profile tailored on biomarkers' evaluation within 48h. Their measurements at 24h contributed the most variability and information both to patients' and to biomarkers' profiles. BNP and cTnI were highly correlated and explained the 40.1% of the total variance, whereas CgA resulted independent and explained the 26.3% of the total variance. CONCLUSIONS Markers' measurements at 24h after PPCI contributed most information to the definition of patients' profile. BNP and cTnI resulted interchangeable in a MM panel for reporting about the extent of necrosis.

Abstract
BACKGROUND The variability of NT-proBNP levels has been studied in heart failure, yet no data exist on these changes over time in hypertensive patients. Furthermore, studies on the relationship between natriuretic peptides and inflammatory status are limited. METHODOLOGY/PRINCIPAL FINDINGS 220 clinically and functionally asymptomatic stable patients (age 59 ± 13, 120 male) out of 252 patients with essential hypertension were followed up, and NT-proBNP was measured at baseline, 12 and 24 months. No differences in NT-proBNP were found with respect to the basal stage in the hypertrophic group, but significant changes were found in non-hypertrophic subjects. The reproducibility of NT-proBNP measurements was better in patients with hypertrophy than in the non-hypertrophic group for the three intervals (stage I-basal; stage II-stage I; stage II-basal) with a reference change value of 34%, 35% and 41%, respectively, in the hypertrophic group. A more elevated coefficient of correlation was obtained in the hypertrophic group than in patients without hypertrophy: basal versus stage I (r = 0.79, p < 0.0001 and r = 0.59, p < 0.0001) and stage I versus stage II (r = 0.86, p < 0.0001 and r = 0.56, p < 0.0001). Finally, levels of NT-proBNP significantly correlated with sTNF-R1 (p < 0.0001) and IL-6 (p < 0.01) during follow-up. A multivariate linear regression analysis showed that sTNF-R1 is an independent factor of NT-proBNP. CONCLUSIONS/SIGNIFICANCE This work shows that there is good stability in NT-proBNP levels in a follow-up study of asymptomatic patients with stable hypertension and left ventricular hypertrophy. As a consequence, assessment of NT-proBNP concentrations may be a useful tool for monitoring the follow-up of hypertensive patients with hypertrophy. Measured variations in peptide levels, exceeding 35% in a 12-month follow-up and 41% in a 24-month follow-up, may indicate an increase in cardiovascular risk, and therefore implies adjustment in the medical treatment. In addition, this study shows a link between neurohormonal and inflammatory activation in these patients.

Abstract
BACKGROUND The aim of this study is to assess the role of novel biomarkers for the diagnostic evaluation of acute coronary syndrome (ACS). METHODS Among 318 patients presenting to an emergency department with acute chest discomfort, we evaluated the diagnostic value of 5 candidate biomarkers (amino terminal pro-B-type natriuretic peptide [NT-proBNP], ischemia modified albumin, heart fatty acid binding protein, high-sensitivity troponin I [hsTnI], and unbound free fatty acids [FFAu]) for detecting ACS, comparing their results with that of conventional troponin T (cTnT). RESULTS Sixty-two subjects (19.5%) had ACS. The sensitivity and negative predictive values of NT-proBNP (73%, 90%) and hsTnI (57%, 89%) were higher than that of cTnT (22%, 84%). Unbound free fatty acids had the highest overall combination of sensitivity (75%), specificity (72%), and negative predictive values (92%) of all the markers examined. A significant increase in the C-statistic for cTnT resulted from the addition of results for NT-proBNP (change 0.09, P = .001), hsTnI (change 0.13, P < .001), and FFAu (change 0.15, P < .001). In integrated discrimination improvement and net reclassification improvement analyses, NT-proBNP, hsTnI, and FFAu added significant diagnostic information to cTnT; when changing the diagnostic criterion standard for ACS to hsTnI, FFAu still added significant reclassification for both events and nonevents. In serial sampling (n = 180), FFAu added important reclassification information to hsTnI. CONCLUSION Among emergency department patients with symptoms suggestive of ACS, neither ischemia modified albumin nor heart fatty acid binding protein detected or excluded ACS, whereas NT-proBNP, hsTnI, or FFAu added diagnostic information to cTnT. In the context of hsTnI results, FFAu measurement significantly reclassified both false negatives and false positives at baseline and in serial samples.

Abstract
AIMS The aim of this study is to simultaneously evaluate the incremental prognostic value of multiple cardiac biomarkers reflecting different underlying pathophysiological processes in a well-characterized population of patients with non-ST-segment acute coronary syndrome (NSTE-ACS). METHODS AND RESULTS We measured cardiac troponin I (cTnI), N-terminal pro B-type natriuretic peptide (NT-proBNP), C-reactive protein, and myeloperodixase (MPO) among 4352 patients with NSTE-ACS in the MERLIN-TIMI 36 (Metabolic Efficiency With Ranolazine for Less Ischaemia in Non-ST Elevation Acute Coronary-Thrombolysis In Myocardial Infarction 36) trial and followed them for a mean of 343 days. When added individually to a multivariable model adjusted for clinical characteristics, the risk of cardiovascular (CV) death rose in a stepwise fashion with increasing quartiles of each biomarker, and when using their pre-defined cut-points [HR(adj) 2.71 (P < 0.001) for cTnI ≥0.03 ng/mL; HR(adj) 3.01 (P < 0.001) for NT-proBNP ≥400 pg/mL; HR(adj) 1.45 (P = 0.019) for high-sensitivity (hs) C-reactive protein ≥15 mg/L; and HR(adj) 1.49 (P = 0.006) for MPO ≥670 pmol/L]. After including all biomarkers, only NT-proBNP and cTnI were independently associated with CV death, and only cTnI with myocardial infarction (MI). The addition of NT-proBNP to a model adjusted for TIMI risk score incorporating cTnI significantly improved both the discrimination and re-classification of the model for CV death and heart failure (HF) while there was no such improvement after the addition of either MPO or hs-C-reactive protein. CONCLUSION In this study of over 4300 patients presenting with NSTEACS, we found that both cTnI and NT-proBNP offer prognostic information beyond that achieved with clinical risk variables for CV death, MI, and HF. Myeloperoxidase and hs-C-reactive protein, while independently associated with some adverse CV outcomes, did not provide substantial incremental prognostic information when evaluated together with cTnI and NT-proBNP.

Abstract
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.

Abstract
Myocardial infarction causes significant mortality and morbidity. Timely diagnosis allows clinicians to risk stratify their patients and select appropriate treatment. Biomarkers have been used to assist with timely diagnosis, while an increasing number of novel markers have been identified to predict outcome following an acute myocardial infarction or acute coronary syndrome. This may facilitate tailoring of appropriate therapy to high-risk patients. This review focuses on a variety of promising biomarkers which provide diagnostic and prognostic information. Heart-type Fatty Acid Binding Protein and copeptin in combination with cardiac troponin help diagnose myocardial infarction or acute coronary syndrome in the early hours following symptoms. An elevated N-Terminal Pro-B-type Natriuretic Peptide has been well validated to predict death and heart failure following a myocardial infarction. Similarly other biomarkers such as Mid-regional pro-Atrial Natriuretic Peptide, ST2, C-Terminal pro-endothelin 1, Mid-regional pro-Adrenomedullin and copeptin all provide incremental information in predicting death and heart failure. Growth differentiation factor-15 and high-sensitivity C-reactive protein predict death following an acute coronary syndrome. Pregnancy associated plasma protein A levels following chest pain predicts risk of myocardial infarction and revascularisation. Some biomarkers such as myeloperoxidase and high-sensitivity C-reactive protein in an apparently healthy population predicts risk of coronary disease and allows clinicians to initiate early preventative treatment. In addition to biomarkers, various well-validated scoring systems based on clinical characteristics are available to help clinicians predict mortality risk, such as the Thrombolysis In Myocardial Infarction score and Global Registry of Acute Coronary Events score. A multimarker approach incorporating biomarkers and clinical scores will increase the prognostic accuracy. However, it is important to note that only troponin has been used to direct therapeutic intervention and none of the new prognostic biomarkers have been tested and proven to alter outcome of therapeutic intervention. Novel biomarkers have improved prediction of outcome in acute myocardial infarction, but none have been demonstrated to alter the outcome of a particular therapy or management strategy. Randomised trials are urgently needed to address this translational gap before the use of novel biomarkers becomes common practice to facilitate tailored treatment following an acute coronary event.

Abstract
BACKGROUND In patients with unstable angina and non-ST elevation myocardial infarction (UA/NSTEMI) two strategies are possible, either a routine invasive strategy where all patients undergo coronary angiography shortly after admission and, if indicated, coronary revascularization; or a conservative strategy where medical therapy alone is used initially, with selection of patients for angiography based on clinical symptoms or investigational evidence of persistent myocardial ischemia. OBJECTIVES To determine the benefits of an invasive compared to conservative strategy for treating UA/NSTEMI in the stent era. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 1), MEDLINE and EMBASE were searched (1996 to February 2008) with no language restrictions. SELECTION CRITERIA Included studies were prospective trials comparing invasive with conservative strategies in UA/NSTEMI. DATA COLLECTION AND ANALYSIS We identified five studies (7818 participants). Using intention-to-treat analysis with random-effects models, summary estimates of relative risk (RR) with 95% confidence interval (CI) were determined for primary end-points of all-cause death, fatal and non-fatal myocardial infarction, all-cause death or non-fatal myocardial infarction, and refractory angina. Further analysis of included studies was undertaken based on whether glycoprotein IIb/IIIa receptor antagonists were used routinely. Heterogeneity was assessed using Chi(2) and variance (I(2) statistic) methods. MAIN RESULTS In the all-study analysis, mortality during initial hospitalization showed a trend to hazard with an invasive strategy (RR 1.59, 95% CI 0.96 to 2.64). The invasive strategy did not reduce death on longer-term follow up. Myocardial infarction rates assessed at 6 to 12 months (5 trials) and 3 to 5 years (3 trials) were significantly decreased by an invasive strategy (RR 0.73, 95% CI 0.62 to 0.86; and RR 0.78, 95% CI 0.67 to 0.92 respectively). The incidence of early (< 4 month) and intermediate (6 to 12 month) refractory angina were both significantly decreased by an invasive strategy (RR 0.47, 95% CI 0.32 to 0.68; and RR 0.67, 95% CI 0.55 to 0.83 respectively), as were early and intermediate rehospitalization rates (RR 0.60, 95% CI 0.41to 0.88; and RR 0.67, 95% CI 0.61 to 0.74 respectively). The invasive strategy was associated with a two-fold increase in the RR of peri-procedural myocardial infarction (as variably defined) and a 1.7-fold increase in the RR of (minor) bleeding with no hazard of stroke. AUTHORS' CONCLUSIONS Compared to a conservative strategy for UA/NSTEMI, an invasive strategy is associated with reduced rates of refractory angina and rehospitalization in the shorter term and myocardial infarction in the longer term. However, the invasive strategy is associated with a doubled risk of procedure-related heart attack and increased risk of bleeding and procedural biomarker leaks. Available data suggest that an invasive strategy may be particularly useful in those at high risk for recurrent events.

Abstract
The effect of body mass index (BMI) on outcomes after primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is not well known. In patients registered in the Korean Acute Myocardial Infarction Registry (KAMIR) between November 2005 and November 2007, 3824 STEMI patients who arrived at hospital within 12h after onset of chest pain and underwent primary PCI were analyzed, and divided into four groups according to their BMI: underweight (BMI<18.5 kg/m(2), n=129); normal weight (18.5 < or =BMI <23.0 kg/m(2), n=1253); overweight (23.0 < or =BMI <27.5 kg/m(2), n=1959); and obese (BMI > or =27.5 kg/m(2), n=483). In-hospital mortality, revascularization in 1 year, mortality in 1 year, and overall mortality were compared between groups. Overweight and obese group were significantly younger, had normal left ventricular ejection fraction, and were more likely to be men with a higher incidence of hypertension, diabetes, and hyperlipidemia. There were no significant differences in symptom-to-door time and door-to-balloon time between groups. Obese patients had significantly lower in-hospital and overall mortalities. Major adverse cardiac events showed a bimodal pattern. Obese STEMI patients treated with primary PCI were associated with lower mortality, which may be explained by better use of medical treatment, hemodynamic stability, and younger age.

Abstract
BACKGROUND AND OBJECTIVE The B-type natriuretic peptide (BNP) has recently emerged as a prognostic marker in acute coronary syndromes (ACS). This role is based on results from randomized trials and other high selected population studies. The aim of this study was to determine the prognostic value of BNP in unselected patients with non-ST-elevated-ACS. PATIENTS AND METHOD BNP plasma concentrations were measured in 100 consecutive patients admitted in 2007 with non-ST-elevated-ACS, taking as cut-off value 80pg/ml (high BNP levels on 48% of patients). RESULTS After one year-of follow-up, 21 major adverse cardiovascular events occurred: 12 ACS, 7 hospitalizations for heart failure and 2 sudden cardiac deaths. No relationship was found between BNP levels and events on follow-up. BNP >80pg/ml was the only independent predictor of heart failure and death. No relationship was found between high levels of BNP and coronary events during the follow-up. CONCLUSIONS BNP was an independent predictor of heart failure and mortality in unselected patients with non-ST-elevated-ACS.

Abstract
OBJECTIVE To explore the relationship between NT-proBNP elevation and prognosis in patients with NSTEACS. BACKGROUND High NT-proBNP levels are related to a worse prognosis in patients with ACS. The precise mechanism by which is not clear. METHODS Serial sampling of NT-proBNP, Troponin T and CK-MB was performed in 23 patients admitted with NSTEACS. Using coronary angiography in each patient a culprit lesion was identified. Proximal lesions were located before or at the first major branch of the parent artery. All other lesions localizations were considered distal. To evaluate the influence of left ventricular systolic function on NT-proBNP levels WMSI was measured by echocardiography. RESULTS Proximal culprit lesion localization was associated with significant higher baseline (mean 506 ng/l, SD 440 ng/l) and peak NT-proBNP levels (mean 1055 ng/l; SD 236 ng/l), as compared to patients with a distal lesion localization. (Baseline: 139 ng/l, SD 140 ng/l, peak: 381 ng/l; SD 64 ng/l). (P = 0.01) NT-proBNP levels were highly correlated to Troponin T and CK-MB peak serum levels. Adjustments for left ventricular dysfunction did not alter these associations. CONCLUSIONS High peak NT-proBNP levels are independently associated with both proximal culprit localization and elevated biochemical markers of myocardial damage. These findings suggest that NT-proBNP levels reflect the amount of jeopardized myocardium and could signify the integral of the extent and severity of an ischemic event.

Abstract
Patients admitted with suspected acute myocardial infarction (MI) constitute a diagnostic, prognostic and therapeutic challenge for the treating physician. Elevation of a marker of myocardial necrosis together with ischemic symptoms and/or ischemic ECG changes are mandatory for the diagnosis of acute MI. Troponin T or I is the preferred marker of myocardial necrosis. The diagnostic process should start as soon as possible. The introduction of prehospital ECG recordings and prehospital administration of thrombolytic treatment in case of ST-segment elevation MI, have been shown to decrease the time from onset of symptoms till treatment considerably, which also translates into saved lives. In contrast, data of the value of prehospital analyses of biochemical markers are still limited. In patients without ST-segment elevation on admission the diagnosis is dependent on repeated measurements of markers of myocardial damage, which together with other biochemical markers (e.g. CRP and BNP/NT-proBNP) also are useful for risk assessment. Patients identified to be at low risk of future cardiac events might be discharged early and, on the contrary, a more intense treatment might be started in patients identified to be at high risk. An elevated troponin concentration is shown to identify patients who benefit from antithrombotic therapy and invasive procedures. Several different risk scoring models based on a combination of clinical variables, ECG-changes and biochemical markers, have been shown to further improve risk assessment and selection of treatment.

Abstract
Background Patients with acute chest pain are often referred to the emergency ward and extensively investigated. Investigations are costly and could induce unnecessary complications, especially with invasive diagnostics. Nevertheless, chest pain patients have high mortalities. Fast identification of high-risk patients is crucial. Therefore several strategies have been developed including specific symptoms, signs, laboratory measurements, and imaging. Methods/Design The Quick Identification of acute Chest pain Study (QICS) will investigate whether a combined use of specific symptoms and signs, electrocardiography, routine and new laboratory measures, adjunctive imaging including electron beam (EBT) computed tomography (CT) and contrast multislice CT (MSCT) will have a high diagnostic yield for patients with acute chest pain. All patients will be investigated according a standardized protocol in the Emergency Department. Serum and plasma will be frozen for future analysis for a wide range of biomarkers at a later time point. The primary endpoint is the safe recognition of low-risk chest pain patients directly at presentation. Secondary endpoint is the identification of a wide range of sensitive predictive clinical markers, chemical biomarkers and radiological markers in acute chest pain patients. Chemical biomarkers will be compared to quantitative CT measurements of coronary atherosclerosis as a surrogate endpoint. Chemical biomarkers will also be compared in head to head comparison and for their additional value. Discussion This will be a very extensive investigation of a wide range of risk predictors in acute chest pain patients. New reliable fast and cheap diagnostic algorithm resulting from the test results might improve chest pain patients' prognosis, and reduce unnecessary costs and diagnostic complications.

Abstract
The GRACE (Global Registry of Acute Coronary Events) risk score has been shown to offer predictive power with regard to death and AMI (acute myocardial infarction) in patients with ACS (acute coronary syndromes). NT-proBNP (N-terminal pro-B-type natriuretic peptide) has also been found to be useful in predicting mortality following ACS. In the present study, we sought to investigate the use of the GRACE score and NT-proBNP levels at predicting risk of early and late deaths following ACS. We studied 1033 patients (740 men, mean age 66.5±12.7 years) with AMI. Blood was drawn once within 24 h following the onset of chest pain. The plasma concentration of NT-proBNP was determined using an in-house non-competitive immunoassay. Patients were GRACE risk scored. The 30-day mortality was 3.7% and the 6-month mortality was 7.8%, and all were related to higher GRACE risk scores (P=0.001 for trend). Higher NT-proBNP levels were also related to increased mortality (P<0.0001). In a Cox proportional hazards model, independent predictors of 30-day and 6-month mortality included NT-proBNP levels and the GRACE risk score. The receiver-operating curve for the GRACE risk score was complemented by NT-proBNP levels for prediction of 30-day mortality [AUC (area under the curve), 0.85] and 6-month mortality (AUC, 0.81). NT-proBNP gives complementary information to the GRACE risk score for predicting early and late mortality. The inclusion of the NT-proBNP blood test is useful in risk-stratifying patients after ACS.

Abstract
OBJECTIVE To examine the influence of age on the predictive value of N-terminal pro-brain natriuretic (NT-proBNP) peptide assay in acute myocardial infarction. DESIGN Prospective observational study. SETTING All intensive care units in one French region. PARTICIPANTS 3291 consecutive patients admitted for an acute myocardial infarction, from the RICO survey (a French regional survey for acute myocardial infarction). MAIN OUTCOME MEASURE Cardiovascular death at 1 year. RESULTS Among the 3291 participants, mean age was 68 (SD 14) years and 2356 (72%) were men. In the study population, the median NT-proBNP concentration was 1053 (interquartile range 300-3472) pg/ml. Median values for age quarters 1 to 4 were 367 (119-1050), 696 (201-1950), 1536 (534-4146), and 3774 (1168-9724) pg/ml (P<0.001). A multiple linear regression analysis was done to determine the factors associated with the pro-peptide concentrations in the overall population. NT-proBNP was mainly associated with age, left ventricular ejection fraction, creatinine clearance, female sex, hypertension, diabetes, and anterior wall infarction. At one year's follow-up, 384 (12%) patients had died from all causes and 372 (11%) from cardiovascular causes. In multivariate analysis, NT-proBNP remained strongly associated with the outcome, beyond traditional risk factors including creatinine clearance and left ventricular ejection fraction, in each age group except in the youngest one (<54 years) (P=0.29). The addition of NT-proBNP significantly improved the performance of the statistical model in the overall study population (-2log likelihood 3179.58 v 3099.74, P<0.001) and in each age quarter including the upper one (1523.52 v 1495.01, P<0.001).The independent discriminative value of NT-proBNP compared with the GRACE score was tested by a diagonal stratification using the median value of the GRACE score and NT-proBNP in older patients (upper quarter). Such stratification strikingly identified a high risk group-patients from the higher NT-proBNP group and with a high risk score-characterised by a risk of death of almost 50% at one year. CONCLUSIONS In this large contemporary non-selected cohort of patients with myocardial infarction, NT-proBNP concentration had incremental prognostic value even in the oldest patients, above and beyond the GRACE risk score and traditional biomarkers after acute myocardial infarction. These data further support the potential interest of clinical trials specifically assessing NT-proBNP measurement as a guide to current treatment strategies, as well as novel strategies, in older patients with acute myocardial infarction.

Abstract
The B-type natriuretic peptides; B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide, are increasing being used as biomarkers for the diagnosis, management and prognostication of cardiac failure, but their application in the peri-operative period is unclear. This review examines the current understanding of the role of B-type natriuretic peptides in both the operative and non-operative settings. Normal values, diagnostic thresholds, monitoring targets and significant prognostic levels are identified. Using this as a background, the role of B-type natriuretic peptides in the prediction of peri-operative mortality and morbidity is examined and potential confounders, such as renal failure and body mass index, which may impact significantly on the utility of the biomarkers, are discussed. Clinical recommendations with regard to its use are made and a research agenda is proposed for future peri-operative studies.

Abstract
Levels of natriuretic peptides, including B-type natriuretic peptide and N-terminal prohormone brain natriuretic peptide, are strong independent predictors of prognosis in acute coronary syndrome (ACS). They are associated with short- and long-term mortality and with the risk of new-onset heart failure, above and beyond the conventional risk factors. Myocardial ischemia and ventricular wall stress are triggers for the release of natriuretic peptides, and although the latter are associated with the severity of the underlying coronary artery disease, they fail to predict recurrent nonfatal ACS. In conclusion, natriuretic peptide values may improve risk stratification in ACS when used in addition to troponin levels and other prognostic markers, but more data are needed to define their role in ACS therapy.

Abstract
Early diagnosis of acute coronary syndromes (ACS) allows for efficient risk stratification, appropriate targeted therapies, and faster patient disposition within crowded emergency departments. Although only troponin testing is recommended for routine use in the 2007 American College of Cardiology/American Heart Association guidelines for non-ST-elevation ACS, emerging data support selected use of other biomarkers, including B-type natriuretic peptides (BNPs) and C-reactive protein. There remains a need to identify additional biomarkers in ACS to enhance risk stratification and to help guide therapeutic decisions in this increasingly complex area of cardiovascular medicine. Cardiac biomarkers may help to diagnosis ACS before cardiomyocyte necrosis, to influence the decision for early invasive treatment, and to provide a means of monitoring response to therapy. In this review, we assess new data in ACS with respect to troponins, BNPs, myeloperoxidase, fatty acid-binding protein, and monocyte chemoattractant protein-1. We also discuss novel biomarkers including growth deficient factor-15 and neopterin.

Abstract
BACKGROUND An elevated body mass index (BMI) has been reported to be associated with a lower rate of death after acute myocardial infarction (AMI). However, waist circumference (WC) may be a better marker of cardiovascular risk than BMI. We used data from a contemporary French population-based cohort of patients with AMI to analyze the impact of WC and BMI on death rates. METHODS AND RESULTS We evaluated 2229 consecutive patients with AMI. Patients were classified according to BMI as normal, overweight, obese, and very obese (BMI <25, 25 to 29.9, 30 to 34.5, and >35 kg/m(2), respectively) and as increased waistline (WC >88/102 cm for women/men) or normal. Half of the patients were overweight (n=1044), and one quarter were obese (n=397) or very obese (n=128). Increased WC was present in half of the patients (n=1110). Increased BMI was associated with a reduced death rate, with a 5% risk reduction for each unit increase in BMI (hazard ratio, 0.95; 95% CI, 0.93 to 0.98; P<0.001). In contrast, WC as a continuous variable had no impact on all-cause death (P=0.20). After adjustment for baseline predictors of death, BMI was not independently predictive of death. The group of patients with high WC but low BMI had increased 1-year death rate. CONCLUSIONS Neither BMI nor WC independently predicts death after AMI. Much of the inverse relationship between BMI and the rate of death after AMI is due to confounding by characteristics associated with survival. This study emphasizes the need to measure both BMI and WC because patients with a high WC and low BMI are at high risk of death.
