- AIMS: galectin-3 is an emerging biomarker which has been studied in relatively small heart failure (HF) cohorts with predominantly systolic HF. We studied the prognostic value of base-line galectin-3 in a large HF cohort, with preserved and reduced left ventricular ejection fraction (LVEF), and compared this to other biomarkers. METHODS: we studied 592 HF patients who had been hospitalized for HF and were followed for 18 months. The primary end-point was a composite of all-cause mortality and HF hospitalization. RESULTS: a doubling of galectin-3 levels was associated with a hazard ratio (HR) of 1.97 (1.62-2.42) for the primary outcome (P < 0.001). After correction for age, gender, BNP, eGFR, and diabetes the HR was 1.38 (1.07-1.78; P = 0.015). Galectin-3 levels were correlated with higher IL-6 and CRP levels (P < 0.002). Changes of galectin-3 levels after 6 months did not add prognostic information to the base-line value (n = 291); however, combining plasma galectin-3 and BNP levels increased prognostic value over either biomarker alone (ROC analysis, P < 0.05). The predictive value of galectin-3 was stronger in patients with preserved LVEF (n = 114) compared to patients with reduced LVEF (P < 0.001). CONCLUSIONS: galectin-3 is an independent marker for outcome in HF and appears to be particularly useful in HF patients with preserved LVEF.

- OBJECTIVES: This study investigated clinical determinants and added prognostic value of HE4 as a biomarker not previously described in heart failure (HF).BACKGROUND: Identification of plasma biomarkers that help to risk stratify HF patients may help to improve treatment.METHODS: Plasma HE4 levels were determined in 567 participants of the COACH (Coordinating study evaluating outcomes of Advising and Counseling in Heart failure). Patients had been hospitalized for HF and were followed for 18 months. The primary endpoint of this study was a composite of all-cause mortality and HF hospitalization.RESULTS: HE4 showed a strong correlation with HF severity, according to New York Heart Association functional class and brain natriuretic peptide (BNP) levels (p < 0.001). HE4 also showed a positive correlation with GDF15 (p < 0.001) and, in addition, correlated with kidney function (estimated glomerular filtration rate [eGFR]; p < 0.001). Cox regression analysis revealed that a doubling of HE4 levels was associated with a hazard ratio (HR) of 1.73 (95% confidence interval [CI]: 1.53 to 1.95) for the primary outcome (p < 0.001). After correction for age, gender, BNP, and eGFR, the HR was 1.46 (95% CI: 1.23 to 1.72; p < 0.001), and after additional adjustment for GDF15, the HR lowered to 1.30 (95% CI: 1.07 to 1.59; p = 0.009). The area under the curve in the receiver-operating characteristic curve analysis increased from 0.727 to 0.752 when HE4 was included in the clinical evaluation (p = 0.051). The integrated discrimination improvement and net reclassification index for reclassification showed significant improvements when HE4 was added to the clinical model, and this remained significant after BNP inclusion in the model.CONCLUSIONS: HE4 plasma levels are correlated with markers of HF severity, show prognostic value, and can improve risk assessment in HF.

- BACKGROUND: psychological stress and depressive symptoms have been implicated with accelerated ageing and increased progression of diseases. Shorter telomere length indicates a more advanced biological age. It is unknown whether psychological well-being is associated with telomere length in patients with the somatic condition of chronic heart failure (CHF). DESIGN: a cross-sectional analysis was used. SETTING: patients were admitted to the hospital with signs and symptoms of CHF. OBJECTIVE: the study aimed to assess the association between telomere length and psychological well-being in patients with CHF. METHODS: telomere length was determined by quantitative polymerase chain reaction in 890 patients with New York Heart Association functional class II to IV CHF. We evaluated the perceived mental health by the validated RAND-36 questionnaire. Depressive symptoms were assessed by the Centre for Epidemiologic Studies Depression scale (CES-D), and the presence of type D personality was evaluated by the DS14. RESULTS: a lower perceived mental health on the RAND-36 score was associated with shorter telomere length. Adjustment for age and gender did not change our findings (standardised beta, 0.11; P-value, 0.002). Telomere length was not associated with the CES-D or DS14 score. CONCLUSION: decreased perceived mental health is associated with shorter leukocyte telomere length in patients with CHF. Future work should determine whether psychological stress accelerates biological ageing.

- AIMS: Anaemia in heart failure (HF) is associated with a poor prognosis. Although inflammation is assumed to be an important cause of anaemia, the association between anaemia and inflammatory markers in patients with HF has not been well established.METHODS: Data from a multicentre randomised clinical trial, in which patients were eligible if they were >18 years of age and admitted for HF (New York Heart Association II-IV), were used. In a subset of 326 patients, haemoglobin (Hb), haematocrit, high sensitivity C-reactive protein (hsCRP), interleukin-(IL) 6, soluble tumour necrosis factor receptor (sTNFR)-1 and erythropoietin (Epo) were measured at discharge and the primary endpoint was all-cause mortality. Follow-up was 18 months.RESULTS: Anaemia (Hb <13 g/dl (men) and <12 g/dl (women)) was present in 40% (130/326) of the study population. Median levels of IL-6, hsCRP and sTNFR-1 were significantly higher in anaemic patients than in non-anaemic patients. Logistic regression demonstrated that each increase in hsCRP values (OR 1.58 per SD log hsCRP; 95% CI 1.09 to 2.29; p=0.016) and each increase in sTNFR-1 values (OR 1.62 per SD log sTNFR-1; 95% CI 1.24 to 2.11; p<0.001) were independently associated with anaemia. Epo (HR 1.31 per log Epo; 95% CI 1.01 to 1.69; p=0.041) and sTNFR-1 (HR 1.47 per log sTNFR-1; 95% CI 1.16 to 1.86; p=0.001) levels were independently associated with outcome.CONCLUSION: Anaemia is present in 40% of patients hospitalised for HF and is independently associated with inflammation.

- AIMS: Vitamin D status has been implicated in the pathophysiology of heart failure (HF). The aims of this study were to determine whether a low vitamin D status is associated with prognosis in HF and whether activation of the renin-angiotensin system (RAS) and inflammatory markers could explain this potential association. METHODS AND RESULTS: We measured 25-hydroxy-vitamin D (25(OH)D), plasma renin activity (PRA), interleukin-6 (IL-6), C-reactive protein (CRP), and the incidence of death or HF rehospitalization in 548 patients with HF. Median age was 74 (64-80) years, left ventricular ejection fraction was 30% (23-42), and mean follow-up was 18 months. Low 25(OH)D levels were associated with female gender (P< 0.001), higher age (P= 0.002), and higher N-terminal pro-brain natriuretic peptide (NT-proBNP) levels (P< 0.001). Multivariable linear regression analysis showed that PRA (P= 0.048), and CRP levels (P= 0.006) were independent predictors of 25(OH)D levels. During follow-up, 155 patients died and 142 patients were rehospitalized. Kaplan-Meier analysis showed that lower 25(OH)D concentration was associated with an increased risk for the combined endpoint (all-cause mortality and HF rehospitalization; log rank test P= 0.045) and increased risk for all-cause mortality (log rank test P= 0.014). After adjustment in a multivariable Cox regression analysis, low 25(OH)D concentration remained independently associated with an increased risk for the combined endpoint [hazard ratio (HR) 1.09 per 10 nmol/L decrease; 95% confidence interval (CI) 1.00-1.16; P= 0.040] and all-cause mortality (HR 1.10 per 10 nmol/L decrease; 95% CI 1.00-1.22; P= 0.049). CONCLUSION: A low 25(OH)D concentration is associated with a poor prognosis in HF patients. Activation of the RAS and inflammation may confer the adverse effects of low vitamin D levels.

- The aim of our study is to investigate the effect of spironolactone on 30-day outcomes in patients with acute heart failure (AHF) and the association between treatment and outcomes stratified by biomarkers. We conducted a secondary analysis of the biomarker substudy of the multicenter COACH (Co-ordinating Study Evaluating Outcomes of Advising and Counseling in Heart Failure) trial involving 534 AHF patients for 30-day mortality and HF rehospitalizations. Spironolactone therapy was initiated and terminated at the discretion of the treating physician; 30-day outcomes were compared between patients who were treated with spironolactone and those who were not. Outcomes with spironolactone therapy. were explored based on N-terminal pro-B-type natriuretic peptide, ST2, galectin-3, and creatinine levels. Spironolactone was prescribed to 297 (55.6%) patients at discharge (158 new and 139 continued). There were 19 deaths and 30 HF rehospitalizations among 46 patients by 30 days. Patients discharged on spironolactone had significantly less 30-day event (hazard ratio 0.538, p = 0.039) after adjustment for multiple risk factors. Initiation of spironolactone in patients who were not on spironolactone before admission was associated with a significant reduction in event rate (hazard ratio 0.362, p = 0.027). The survival benefit of spironolactone was more prominent in patient groups with elevations of creatinine, N-terminal pro B-type natriuretic peptide, ST2, or galectin-3. In conclusion, AHF patients who received spironolactone during hospitalization had significantly fewer 30-day mortality and HF rehospitalizations, especially in high-risk patients.

- Background-Syndecan-1 is a member of the proteoglycan family involved in cell-matrix interactions. Experimental studies showed that syndecan-1 is associated with inflammation in acute myocardial infarction and remodeling. The goal of this study was to explore the role of syndecan-1 in human heart failure (HF). Methods and Results-We analyzed plasma syndecan-1 levels in 567 patients with chronic HF. Primary end point was a composite of all-cause mortality and rehospitalization for HF at 18 months. Mean age was 71.0 +/- 11.0 years, 38% was women, and mean left ventricular ejection fraction was 32.5 +/- 14.0%. Median syndecan-1 levels were 20.1 ng/mL (interquartile range, 13.9-27.7 ng/mL). Patients with higher syndecan-1 levels were more often men, had higher N-terminal probrain-type natriuretic peptide levels, and worse renal function. Multivariable regression analyses showed a positive correlation between syndecan-1 levels and markers of fibrosis and remodeling but no correlation with inflammation markers. Interaction analysis revealed an interaction between left ventricular ejection fraction and syndecan-1 (P=0.047). A doubling of syndecan-1 was associated with an increased risk of the primary outcome in patients with HF with preserved ejection fraction (hazard ratio, 2.10; 95% confidence interval, 1.14-3.86; P=0.017) but not in patients with HF with reduced ejection fraction (hazard ratio, 0.95; 95% confidence interval, 0.71-1.27; P=0.729). Finally, syndecan-1 enhanced risk classification in patients with HF with preserved ejection fraction when added to a prediction model with established risk factors. Conclusions-In patients with HF, syndecan-1 levels correlate with fibrosis biomarkers pointing toward a role in cardiac remodeling. Syndecan-1 was associated with clinical outcome in patients with HF with preserved ejection fraction but not in patients with HF with reduced ejection fraction.

- BACKGROUND: Telomeres are causally involved in senescence. Senescence is a potential factor in the pathogenesis and progression of heart failure. In heart failure telomeres are shorter, but the prognostic value associated with telomere length has not been defined. METHODS: Telomere length was prospectively determined by quantitative polymerase chain reaction in 890 patients with New York Heart Association (NYHA) functional class II to IV heart failure. After 18 months, we examined the association between telomere length and the predefined primary end-point: time to death or hospitalization for heart failure. RESULTS: Mean age of the patients was 71 years, 39% were women, 51% were in NYHA class II, and 49% were in class III/IV. A total of 344 patients reached the primary end-point (130 deaths and 214 hospitalizations). Patients with shorter telomeres were at an increased risk of reaching the primary end-point (hazard ratio 1.79; 95% confidence interval (CI) 1.21-2.63). In multivariate analysis shorter telomere length remained associated with a higher risk for death or hospitalization (hazard ratio, 1.74; 95% CI 1.07-2.95) after adjustment for age of heart failure onset, gender, hemoglobin, renal function, and N-terminal pro-B-type natriuretic peptide level, a history of stroke, atrial fibrillation, and diabetes. CONCLUSIONS: Shorter length of telomeres predicts the occurrence of death or hospitalization in patients with chronic heart failure.

- AIMS: Anaemia is highly prevalent and associated with poor prognosis in patients with chronic heart failure (CHF). Reduced erythroid proliferation capacity of haematopoietic progenitor cells is associated with reduced telomere length, a marker of cellular ageing. We hypothesize that short telomere length contributes to the susceptibility to develop anaemia in patients with CHF. METHODS AND RESULTS: We studied 875 CHF patients, of whom 254 (29%) fulfilled the WHO criteria of anaemia. Telomere length in DNA from peripheral leucocytes was measured with real-time quantitative polymerase chain reaction. Age, gender, and baseline differences adjusted telomere length was correlated with haemoglobin levels (partial r = 0.130; P = 0.011). One standard deviation shorter telomere length was associated with an increased risk of having anaemia [odds ratio (OR), 1.31; 95% confidence interval (CI), 1.12-1.53; P = 0.001]. This observation was not affected by adjustment for potential confounders (OR, 1.38; 95% CI, 1.05-1.81; P = 0.021 after adjustment for age, gender, erythropoietin levels, renal function, left ventricular ejection fraction, age of CHF onset, blood pressure, history of stroke, diabetes, and B-type natriuretic peptide levels). CONCLUSION: Shorter telomere length increases the odds of having anaemia in CHF patients. This finding supports the hypothesis that cellular ageing in CHF contributes to the susceptibility to develop anaemia.

- BACKGROUND: Endogenous erythropoietin is increased in patients with heart failure (HF). Previous small-scale data suggest that these erythropoietin levels are related to prognosis. This study aims to analyze the clinical and prognostic value of erythropoietin levels in relation to hemoglobin in a large cohort of HF patients. METHODS AND RESULTS: In patients hospitalized for HF, endogenous erythropoietin levels were measured at discharge and after 6 months. In anemic patients, the relation between erythropoietin and hemoglobin levels was determined by calculating the observed/predicted ratio of erythropoietin levels. We studied data from 605 patients with HF. Mean age was 71+/-11 years; 62% were male; and mean left ventricular ejection fraction was 0.33+/-0.14. Median erythropoietin levels were 9.6 U/L at baseline and 10.5 U/L at 6 months. Higher erythropoietin levels at baseline were independently related to an increased mortality at 18 months (hazard ratio, 2.06; 95% confidence interval, 1.40 to 3.04; P<0.01). In addition, persistently elevated erythropoietin levels (higher than median at baseline and at 6 months) were related to an increased mortality risk (hazard ratio, 2.24; 95% confidence interval, 1.02 to 4.90; P=0.044). The observed/predicted ratio was determined in a subset of anemic patients, 79% of whom had erythropoietin levels lower than expected and 9% had levels higher than expected on the basis of their hemoglobin. Multivariate Cox regression analysis revealed that a higher observed/predicted ratio was related to an increased mortality risk (hazard ratio, 3.52; 95% confidence interval, 1.53 to 8.12; P=0.003). CONCLUSIONS: Erythropoietin levels predict mortality in HF patients, and persistently elevated levels have an independent prognostic value. In anemic HF patients, the majority had a low observed/predicted ratio. However, a higher observed/predicted ratio may be related to an independent increased mortality risk.

- AIMS: Atrial fibrillation (AF) is common in heart failure (HF), but few data regarding the prognostic relevance of AF are available in HF patients with preserved left ventricular ejection fraction (HF-PEF). We aimed to study the clinical impact of AF vs. sinus rhythm (SR) in stabilized HF patients with reduced left ventricular ejection fraction (HF-REF) and in those with preserved left ventricular ejection fraction (HF-PEF). METHODS AND RESULTS: We studied 927 patients with stable HF, of whom 336 (36%) had AF. N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations were measured at baseline and patients were followed for 18 months. We compared time to first HF (re-)hospitalization or death between patients with AF and SR. Atrial fibrillation was present at baseline in 215 (35%) patients with HF-REF (mean LVEF 0.25 + 0.08) and in 121 (40%) patients with HF-PEF (mean LVEF 0.50 + 0.09). Plasma NT-proBNP levels were similar in AF and SR patients (median 2398 vs. 2532 pg/mL, P = 0.74). Atrial fibrillation was independently associated with elevated NT-proBNP levels in HF-PEF, but not in HF-REF patients (multivariable B = 0.33, P= 0.047 and B = 0.03; P = 0.89, respectively). After 18 months of follow-up, the presence of AF was an independent predictor of death or HF hospitalization in HF-PEF (multivariable hazard ratio 1.49 (95% CI 1.04-2.14), P = 0.03), but not in HF-REF patients (1.05 (CI 95% 0.80-1.38), P = 0.72). CONCLUSION: Atrial fibrillation is equally common in patients with HF-PEF and HF-REF. In HF-PEF, but not in HF-REF patients, AF was associated with higher NT-proBNP levels and was independently related to death or HF hospitalization.

- AimsA-type and B-type natriuretic peptides are established markers in chronic heart failure (HF). C-type natriuretic peptide (CNP) belongs to the same peptide family, but is predominantly localized in the endothelium. The prognostic role of CNP in heart failure has not been established. The aim of the study was to determine the prognostic power and clinical correlates of the N-terminal part of pro CNP (NT-proCNP) in patients with chronic HF. Methods and resultsIn 567 hospitalized heart failure patients, NT-proCNP levels were measured at hospital discharge. The primary endpoint was a combined endpoint of all-cause mortality and HF hospitalization after 18 months. Heart failure with a preserved ejection fraction (HFpEF) was pre-defined as an LVEF greater than40%. Mean (SD) age was 71 +/- 11years, 62% were male, mean LVEF was 32 +/- 14%, and 23% had HFpEF. In multivariate linear regression, NT-proCNP levels showed a positive correlation with NT-proBNP levels and parameters of renal function, whereas a negative correlation with female sex and vascular endothelial growth factor was observed. After 18 months follow-up, 240 patients reached the combined endpoint. We observed interaction between NT-proCNP and LVEF for outcome (P=0.046). Multivariate analyses revealed NT-proCNP to be strongly predictive for the primary endpoint [hazard ratio (HR) 1.78, 95% confidence interval (CI) 1.18-2.67, P=0.006) in patients with HFpEF, but not in patients with a reduced ejection fraction (HFrEF) (HR 1.07, 95% CI 0.81-1.43, P=0.616). Finally, reclassification showed significant additive value in patients with HFpEF (Pless than0.001), but not in those with HFrEF (P=0.453). Conclusionless thanp id="ejhf140-para-0003"greater thanNT-proCNP is a strong independent marker for outcome in patients with HFpEF, but not in those with HFrEF.

- The ESC-HF Pilot survey was aimed to describe clinical epidemiology and 1-year outcomes of outpatients and inpatients with heart failure (HF). The pilot phase was also specifically aimed at validating structure, performance, and quality of the data set for continuing the survey into a permanent Registry. The ESC-HF Pilot study is a prospective, multicentre, observational survey conducted in 136 Cardiology Centres in 12 European countries selected to represent the different health systems across Europe. All outpatients with HF and patients admitted for acute HF on 1 day per week for eight consecutive months were included. From October 2009 to May 2010, 5118 patients were included: 1892 (37) admitted for acute HF and 3226 (63) patients with chronic HF. The all-cause mortality rate at 1 year was 17.4 in acute HF and 7.2 in chronic stable HF. One-year hospitalization rates were 43.9 and 31.9, respectively, in hospitalized acute and chronic HF patients. Major regional differences in 1-year mortality were observed that could be explained by differences in characteristics and treatment of the patients. The ESC-HF Pilot survey confirmed that acute HF is still associated with a very poor medium-term prognosis, while the widespread adoption of evidence-based treatments in patients with chronic HF seems to have improved their outcome profile. Differences across countries may be due to different local medical practice as well to differences in healthcare systems. This pilot study also offered the opportunity to refine the organizational structure for a long-term extended European network.

- Worsening renal function, which is associated with adverse outcomes, often develops in patients with acute heart failure. Experimental and clinical studies suggest that counterregulatory responses mediated by adenosine may be involved. We tested the hypothesis that the use of rolofylline, an adenosine A1-receptor antagonist, would improve dyspnea, reduce the risk of worsening renal function, and lead to a more favorable clinical course in patients with acute heart failure.

- Despite disparities in pathophysiology and disease manifestation between male and female patients with heart failure, studies focusing on sex differences in biomarkers are scarce. The purpose of this study was to assess sex-specific variation in clinical characteristics and biomarker levels to gain more understanding of the potential pathophysiological mechanisms underlying sex differences in heart failure. less thanbrgreater than less thanbrgreater thanBaseline demographic and clinical characteristics, multiple biomarkers, and outcomes were compared between men and women in 567 patients. The mean age of the study group was 71 11 years and 38 were female. Women were older, had a higher body mass index and left ventricular ejection fraction, more hypertension, and received more diuretic and antidepressant therapy, but less ACE-inhibitor therapy compared with men. After 3 years, all-cause mortality was lower in women than men (37.0 vs. 43.9, multivariable hazard ratio 0.64; 95 confidence interval 0.450.92, P 0.016). Levels of biomarkers related to inflammation [C-reactive protein, pentraxin 3, growth differentiation factor 15 (GDF-15), and interleukin 6] and extracellular matrix remodelling (syndecan-1 and periostin) were significantly lower in women compared with men. N-terminal pro-brain natriuretic peptide, TNF-R1a, and GDF-15 showed the strongest interaction between sex and mortality. less thanbrgreater than less thanbrgreater thanFemale heart failure patients have a distinct clinical presentation and better outcomes compared with male patients. The lower mortality was independent of differences in clinical characteristics, but differential sex associations between several biomarkers and mortality might partly explain the survival difference.

- Aims Co-morbidities frequently accompany heart failure (HF), contributing to increased morbidity and mortality, and an impairment of quality of life. We assessed the prevalence, determinants, regional variation, and prognostic implications of co-morbidities in patients with chronic HF in Europe. Methods and results A total of 3226 European outpatients with chronic HF were included in this analysis of the European Society of Cardiology (ESC) Heart Failure Pilot Survey. The following co-morbidities were considered: diabetes, hyper- and hypothyroidism, stroke, COPD, sleep apnoea, chronic kidney disease (CKD), and anaemia. Prognostic implications of co-morbidities were evaluated using population attributable risks (PARs), and patients were divided into geographic regions. Clinical endpoints were all-cause mortality and HF hospitalization. The majority of patients (74%) had a least one co-morbidity, the most prevalent being CKD (41%), anaemia (29%), and diabetes (29%). Co-morbidities were independently associated with higher age (P less than 0.001), higher NYHA functional class (P less than 0.001), ischaemic aetiology of HF (P less than 0.001), higher heart rate (P = 0.011), history of hypertension (P less than 0.001), and AF (P less than 0.001). Only diabetes, CKD, and anaemia were independently associated with a higher risk of mortality and/or HF hospitalization. There were marked regional differences in prevalence and prognostic implications of co-morbidities. Prognostic implications of co-morbidities (PARs) were: CKD = 41%, anaemia = 37%, diabetes = 14%, COPD = 10%, and less than10% for all other co-morbidities. Conclusion In this pilot survey, co-morbidities are prevalent in patients with chronic HF and are related to the severity of the disease. The presence of diabetes, CKD, and anaemia was independently related to increased mortality and HF hospitalization, with the highest PAR for CKD and anaemia.

- Background In patients with heart failure, renal dysfunction is associated with a poor outcome. We aimed to assess the prognostic value of plasma neutrophil gelatinase-associated lipocalin (NGAL), a novel marker of renal tubular damage, in patients with heart failure with or without renal dysfunction, and compare it with 2 frequently used biomarkers of chronic kidney disease. Methods and Results Plasma NGAL, estimated glomerular filtration rate (eGFR), and cystatin C were assessed in 562 patients with heart failure. Chronic kidney disease was defined as eGFRless than60 mL/min per 1.73 m(2). Outcome was all-cause mortality at 36 months. Mean age was 7111 years, 61% were men, and 97% were in New York Heart Association functional class II/III. Mean baseline eGFR was 54 +/- 20 mL/min per 1.73 m(2), mean cystatin C was 11.2 (7.7-16.2) mg/L, and median plasma NGAL was 85 (60-123) ng/mL. Higher plasma NGAL levels were independently associated with an increased risk of all-cause mortality, in patients with and without chronic kidney disease (hazard ratio [per SD increase in log NGAL]=1.45 [1.22-1.72]; Pless than0.001 and hazard ratio=1.51 [1.06-2.16]; P=0.023, respectively). Similarly, both in patients with high and low cystatin C (median cut-off), higher plasma NGAL levels were independently associated with an increased risk of all-cause mortality. Moreover, when NGAL was entered in the multivariable risk prediction model, eGFR (P=0.616) and cystatin C (P=0.937) were no longer associated with mortality. Conclusions Plasma NGAL predicts mortality in patients with heart failure, both in patients with and without chronic kidney disease and is a stronger predictor for mortality than the established renal function indices eGFR and cystatin C.

- Objectives This study sought to determine the prognostic value of B-type natriuretic peptide (BNP) in patients with heart failure with preserved ejection fraction (HFPEF), in comparison to data in HF patients with reduced left ventricular (LV) EF (andlt;= 40%). less thanbrgreater than less thanbrgreater thanBackground Management of patients with HFPEF is difficult. BNP is a useful biomarker in patients with reduced LVEF, but data in HFPEF are scarce. less thanbrgreater than less thanbrgreater thanMethods In this study, 615 patients with mild to moderate HF (mean age 70 years, LVEF 33%) were followed for 18 months. BNP concentrations were measured at baseline and were related to the primary outcome, that is, a composite of all-cause mortality and HF hospitalization, and to mortality alone. The population was divided in quintiles, according to LVEF, and patients with reduced LVEF were compared with those with HFPEF. less thanbrgreater than less thanbrgreater thanResults There were 257 patients (42%) who had a primary endpoint and 171 (28%) who died. BNP levels were significantly higher in patients with reduced LVEF than in those with HFPEF (p andlt; 0.001). BNP was a strong predictor of outcome, but LVEF was not. Importantly, if similar levels of BNP were compared across the whole spectrum of LVEF, and for different cutoff levels of LVEF, the associated risk of adverse outcome was similar in HFPEF patients as in those with reduced LVEF. less thanbrgreater than less thanbrgreater thanConclusions BNP levels are lower in patients with HFPEF than in patients with HF with reduced LVEF, but for a given BNP level, the prognosis in patients with HFPEF is as poor as in those with reduced LVEF.

- Introduction Advanced glycation end products (AGEs) are increased in patients with heart failure (HF). We studied the predictive value of plasma AGEs N-E-(carboxymethyl) lysine (CML), pentosidine, and the soluble form of its receptor (sRAGE) in a large HF population. less thanbrgreater than less thanbrgreater thanMethods In 580 patients hospitalized with HF, plasma AGEs were measured before discharge when patients were clinically stable. Patients were followed for a period of 18 months. Primary end point was a composite of death and HF admissions. CML was determined by liquid chromatography mass spectrometry, pentosidine by high-performance liquid chromatography and sRAGE by sequential sandwich immunoassay. less thanbrgreater than less thanbrgreater thanResults Mean age was 71 +/- 11 years, 62% were men, and mean left ventricular ejection fraction was 0.32 +/- 0.14. At baseline, mean CML level was 2.16 +/- 0.73 mu mol/L, median pentosidine was 0.043 (0.030-0.074) mu mol/L, and median sRAGE level was 2.92 (1.90-4.59) ng/mL. CML and pentosidine levels were independently related to the composite end-point (HR, 1.20 per SD; 95% CI, 1.05-1.37; P = .01 and HR, 1.15 per SD; 95% CI, 1.00-1.31; P = .045, respectively) and HF hospitalization (HR, 1.27 per SD; 95% CI, 1.10-1.48; P = .001 and HR, 1.27 per SD; 95% CI, 1.10-1.47; P = .001, respectively). Furthermore, CML levels were independently related to increased mortality (P = .006). Whereas sRAGE levels were univariately predictive for outcome, in multivariate models sRAGE did not reach statistical significance. less thanbrgreater than less thanbrgreater thanDiscussion In HF patients, both CML and pentosidine predict HF hospitalization and the combined primary end-point (mortality or HF-hospitalization), whereas sRAGE did not predict events. In addition, CML was significantly and independently associated with a higher risk for mortality. (Am Heart J 2012;164:742-749.e3.)
