Aims: Although diabetes mellitus (DM) is a common co-morbidity in chronic heart failure (HF) patients, European data on concurrent HF and DM treatment are lacking. Therefore, we have studied the HF treatment of patients with and without DM. Additionally, with the recent breakthrough of sodium–glucose cotransporter 2 (SGLT2) inhibitors in the field of HF, we studied the potential impact of this new drug in a large cohort of HF patients. Methods and results: A total of 7488 patients with chronic HF with a left ventricular ejection fraction 2, P Conclusions: In this large real-world HF registry, a high prevalence of DM was observed and diabetics more often received guideline-recommended target doses. Based on current evidence, the majority of patients would fulfil the enrichment criteria of SGLT2 trials in HF and the impact of this new drug class will be large.

Background Clinical management of heart failure with preserved ejection fraction (HFpEF) centres on treating comorbidities and is likely to vary between countries. Thus, to provide insight into the current management of HFpEF, studies from multiple countries are required. We evaluated the clinical profiles and current management of patients with HFpEF in the Netherlands. Methods We included 2153 patients with HFpEF (defined as a left ventricular ejection fraction ≥ 50%) from the CHECK-HF registry, which included patients from 2013 to 2016. Results Median age was 77 (IQR 15) years, 55% were women and the most frequent comorbidities were hypertension (51%), renal insufficiency (45%) and atrial fibrillation (AF, 38%). Patients between 65 and 80 years and those over 80 years had on average more comorbidities (up to 64% and 74%, respectively, with two or more comorbidities) than patients younger than 65 years (38% with two or more comorbidities, p-value Conclusion The medical HFpEF profile is determined by the underlying comorbidities, sex and age. Comorbidities are highly prevalent in HFpEF patients, especially in elderly HFpEF patients. Despite the lack of evidence, many HFpEF patients receive regular beta-blockers, RAS inhibitors and MRAs, often for the treatment of comorbidities.

BackgroundWe assessed the prognostic significance of absolute and percentage change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients hospitalised for acute decompensated heart failure with preservedejection fraction (HFpEF) versus heart failure with reduced ejection fraction (HFrEF).MethodsPatients with left ventricular ejection fraction ≥50% were categorised as HFpEF (n=283), while those with ResultsDischarge NT-proBNP levels predicted outcome similarly in HFpEF and HFrEF: for any 2.7-factor increase in NT-proBNP levels, the HR for mortality was 2.14 for HFpEF (95% CI 1.48 to 3.09) and 1.96 for HFrEF (95% CI 1.60 to 2.40). Mortality prediction was equally possible for NT-proBNP reduction of ≤30% (HR 4.60, 95% CI 1.47 to 14.40 and HR 3.36, 95% CI 1.93 to 5.85 for HFpEF and HFrEF, respectively) and for >30%–60% (HR 3.28, 95% CI 1.07 to 10.12 and HR 1.79, 95% CI 0.99 to 3.26, respectively), compared with mortality in the reference groups of >60% reductions in NT-proBNP levels. Prognostically relevant comorbidities were more often present in patients with HFpEF than patients with HFrEF in low (≤3000 pg/mL) but not in high (>3000 pg/mL) NT-proBNP discharge categories.ConclusionsOur study highlights—after demonstrating that NT-proBNP levels confer the same relative risk information in HFpEF as in HFrEF—the possibility that comorbidities contribute relatively more to prognosis in patients with HFpEF with lower NT-proBNP levels than in patients with HFrEF.

Background: Insulin-like Growth Factor Binding Protein 2 (IGFBP2) showed greater heart failure (HF) diagnostic accuracy than the "grey zone" B-type natriuretic peptides, and may have prognostic utility as well.Objectives: To determine if IGFBP2 provides independent information on cardiovascular mortality in HF.Methods: A retrospective study of 870 HF patients from 3 independent international cohorts. Presentation IGFBP2 plasma levels were measured by EUSA, and patients were followed from 1 year (Maastricht. Netherlands) to 6 years (Atlanta, GA, USA and Toulouse, France). Multivariate analysis, Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI) were performed in the 3 cohorts. The primary outcome was cardiovascular mortality.Results: In multivariate Cox proportional hazards analysis, the highest quartile of IGFBP2 was associated with mortality in the Maastricht cohort (adjusted hazard ratio 1.69 (95% CI 1.18-2.41), p = 0.004) and in the combined Atlanta and Toulouse cohorts (adjusted hazard ratio 2.04 (95%CI, 13-3.3), p = 0.003). Adding IGFBP2 to a clinical model allowed a reclassification of adverse outcome risk in the Maastricht cohort (NRI - 18.7% p = 0.03; IDI - 3.9% p = 0.02) and with the Atlanta/Toulouse patients (NRI of 40.4% p = 0.01, 31,2% p = 0.04, 315% p = 0,02 and IDI of 2,9% p = 0,0005, 3.1% p = 0,0005 and 4,2%, p = 0.0005, fora follow-up of 1, 2 and 3 years, respectively).Conclusion: In 3 international cohorts, IGFBP2 level is a strong prognostic factor for cardiovascular mortality in HF, adding information to natriuretic monitoring and usual clinical markers, that should be further prospectively evaluated for patients optimized care.

Objectives The aim of this study was to analyze the dynamic changes in renal function in combination with dynamic changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients hospitalized for acute decompensated heart failure (ADHF). Background Treatment of ADHF improves cardiac parameters, as reflected by lower levels of NT-proBNP. However this often comes at the cost of worsening renal parameters (e.g., serum creatinine, estimated glomerular filtration rate [eGFR], or serum urea). Both the cardiac and renal markers are validated indicators of prognosis, but it is not yet clear whether the benefits of lowering NT-proBNP are outweighed by the concomitant worsening of renal parameters. Methods This study was an individual patient data analysis assembled from 6 prospective cohorts consisting of 1,232 patients hospitalized for ADHF. Endpoints were all-cause mortality and the composite of all-cause mortality and/or readmission for a cardiovascular reason within 180 days after discharge. Results A significant reduction in NT-proBNP was not associated with worsening of renal function (WRF) or severe WRF (sWRF). A reduction of NT-proBNP of more than 30% during hospitalization determined prognosis (all-cause mortality hazard ratio [HR]: 1.81; 95% confidence Interval [CI]: 1.32 to 2.50; composite endpoint: HR: 1.36, 95% CI: 1.13 to 1.64), regardless of changes in renal function and other clinical variables. Conclusions When we defined prognosis, NT-proBNP changes during hospitalization for treatment of ADHF prevailed over parameters for worsening renal function. Severe WRF is a measure of prognosis, but is of lesser value than, and independent of the prognostic changes induced by adequate NT-proBNP reduction. This suggests that in ADHF patients it may be warranted to strive for an optimal decrease in NT-proBNP, even if this induces WRF.

Aims Previous analyses suggest that heart failure (HF) therapy guided by (N-terminal pro-)brain natriuretic peptide (NT-proBNP) might be dependent on left ventricular ejection fraction, age and co-morbidities, but the reasons remain unclear. Methods and results To determine interactions between (NT-pro)BNP-guided therapy and HF with reduced [ejection fraction (EF) ≤45%; HF with reduced EF (HFrEF), n = 1731] vs. preserved EF [EF > 45%; HF with preserved EF (HFpEF), n = 301] and co-morbidities (hypertension, renal failure, chronic obstructive pulmonary disease, diabetes, cerebrovascular insult, peripheral vascular disease) on outcome, individual patient data (n = 2137) from eight NT-proBNP guidance trials were analysed using Cox-regression with multiplicative interaction terms. Endpoints were mortality and admission because of HF. Whereas in HFrEF patients (NT-pro)BNP-guided compared with symptom-guided therapy resulted in lower mortality [hazard ratio (HR) = 0.78, 95% confidence interval (CI) 0.62–0.97, P = 0.03] and fewer HF admissions (HR = 0.80, 95% CI 0.67–0.97, P = 0.02), no such effect was seen in HFpEF (mortality: HR = 1.22, 95% CI 0.76–1.96, P = 0.41; HF admissions HR = 1.01, 95% CI 0.67–1.53, P = 0.97; interactions P < 0.02). Age (74 ± 11 years) interacted with treatment strategy allocation independently of EF regarding mortality (P = 0.02), but not HF admission (P = 0.54). The interaction of age and mortality was explained by the interaction of treatment strategy allocation with co-morbidities. In HFpEF, renal failure provided strongest interaction (P < 0.01; increased risk of (NT-pro)BNP-guided therapy if renal failure present), whereas in HFrEF patients, the presence of at least two of the following co-morbidities provided strongest interaction (P < 0.01; (NT-pro)BNP-guided therapy beneficial only if none or one of chronic obstructive pulmonary disease, diabetes, cardiovascular insult, or peripheral vascular disease present). (NT-pro)BNP-guided therapy was harmful in HFpEF patients without hypertension (P = 0.02). Conclusion The benefits of therapy guided by (NT-pro)BNP were present in HFrEF only. Co-morbidities seem to influence the response to (NT-pro)BNP-guided therapy and may explain the lower efficacy of this approach in elderly patients.

Aims NT-proBNP is a strong predictor for readmissions and mortality in acute decompensated heart failure (ADHF) patients. We assessed whether absolute or relative NT-proBNP levels should be used as pre discharge treatment target. Methods and results Our study population was assembled from seven ADHF cohorts. We defined absolute ( 30, >50, and >70%). Population attributable risk fraction (PARF) is the proportion of all-cause 6-month mortality in the population that would be reduced if all patients attain the NT-proBNP target. PARF was determined for each target as well as the percentage of patients attaining the NT-proBNP target. Attainability was investigated by logistic regression analysis. A total of 1266 patients [age 74 (64–80), 60% male] was studied. For every absolute NT-proBNP level, a corresponding percentage reduction was found that resulted in similar PARFs. The highest PARF (∼60–70%) was observed for 70%, but attainability was low (27% and 22%, respectively). The strongest predictor for not attaining these targets was admission NT-proBNP. In admission NT-proBNP tertiles, PARFs were significantly different for absolute, but not for relative targets. Conclusion In an ADHF population, pre-discharge absolute or relative NT-proBNP targets may both be useful as they have similar effects on PARF. However, depending on admission NT-proBNP, absolute targets show varying PARFs, while PARFs for relative targets were similar. A relative target is predicted to reduce mortality consistently across the whole spectrum of ADHF patients, while this is not the case using a single absolute target.

Background: Diagnostic biomarkers for heart failure (HF) such as the natriuretic peptides (NPs) are widely used but have limitations. Innovative biomarkers could provide improved diagnostic performance. Methods: We launched a prospective case-control proteomic study and investigated for polypeptides specific to HF through a capillary electrophoresis-mass spectrometry (CE-MS) proteomic analysis. The putative biomarker was identified by Orbitrap liquid chromatography-MS, validated by western blot, then by ELISA using plasmas from multicentric international cohorts. A rat model of HF was tested for biomarker expression levels. Results: We identified insulin like growth factor binding protein 2 (IGFBP2) as a new diagnostic biomarker for HF with a high sensitivity and specificity (AUC = 0.93; 95% CI, 0.89-0.96; p

Rationale: To maintain cardiac mechanical and structural integrity after an ischemic insult, profound alterations occur within the extracellular matrix. Osteoglycin is a small leucine-rich proteoglycan previously described as a marker of cardiac hypertrophy. Objective: To establish whether osteoglycin may play a role in cardiac integrity and function after myocardial infarction (MI). Methods and Results: Osteoglycin expression is associated with collagen deposition and scar formation in mouse and human MI. Absence of osteoglycin in mice resulted in significantly increased rupture-related mortality with tissue disruption, intramyocardial bleeding, and increased cardiac dysfunction, despite equal infarct sizes. Surviving osteoglycin null mice had greater infarct expansion in comparison with wild-type mice because of impaired collagen fibrillogenesis and maturation in the infarcts as revealed by electron microscopy and collagen polarization. Absence of osteoglycin did not affect cardiomyocyte hypertrophy in the remodeling remote myocardium. In cultured fibroblasts, osteoglycin knockdown or supplementation did not alter transforming growth factor-β signaling. Adenoviral overexpression of osteoglycin in wild-type mice significantly improved collagen quality, thereby blunting cardiac dilatation and dysfunction after MI. In osteoglycin null mice, adenoviral overexpression of osteoglycin was unable to prevent rupture-related mortality because of insufficiently restoring osteoglycin protein levels in the heart. Finally, circulating osteoglycin levels in patients with heart failure were significantly increased in the patients with a previous history of MI compared with those with nonischemic heart failure and correlated with survival, left ventricular volumes, and other markers of fibrosis. Conclusions: Increased osteoglycin expression in the infarct scar promotes proper collagen maturation and protects against cardiac disruption and adverse remodeling after MI. In human heart failure, osteoglycin is a promising biomarker for ischemic heart failure.

Aims Renal failure is a major challenge in treating heart failure (HF) patients. HF medication may deteriorate renal function, but the impact thereof on outcome is unknown. We investigated the effects of HF medication on worsening renal function (WRF) and the relationship to outcome. Methods and results This post-hoc analysis of TIME-CHF (NT-proBNP-guided vs. symptom-guided management in chronic HF) included patients with LVEF ≤45% and ≥1 follow-up visit (n = 462). WRF III was defined as a rise in serum creatinine ≥0.5 mg/dL (i.e. 44.2 µmol/L) at any time during the first 6 months. Four classes of medication were considered: loop diuretics, beta-blockers, renin–angiotensin system (RAS)-blockers, and spironolactone. Functional principal component analysis of daily doses was used to comprehend medication over time. All-cause mortality after 18 months was the primary outcome. Interactions between WRF, medication, and outcome were tested. Patients with WRF III received on average higher loop diuretic doses (P = 0.0002) and more spironolactone (P = 0.02), whereas beta-blockers (P = 0.69) did not differ and lower doses of RAS-blockers were given (P = 0.09). There were significant interactions between WRF III, medicationn and outcome. Thus, WRF III was associated with poor prognosis if high loop diuretic doses were given (P = 0.001), but not with low doses (P = 0.29). The opposite was found for spironolactone (poor prognosis in the case of WRF III with no spironolactone, P

Aims Natriuretic peptide-guided (NP-guided) treatment of heart failure has been tested against standard clinically guided care in multiple studies, but findings have been limited by study size. We sought to perform an individual patient data meta-analysis to evaluate the effect of NP-guided treatment of heart failure on all-cause mortality. Methods and results ligible randomized clinical trials were identified from searches of Medline and EMBASE databases and the Cochrane Clinical Trials Register. The primary pre-specified outcome, all-cause mortality was tested using a Cox proportional hazards regression model that included study of origin, age (= 75 years), and left ventricular ejection fraction (LVEF, 45%) as covariates. Secondary endpoints included heart failure or cardiovascular hospitalization. Of 11 eligible studies, 9 provided individual patient data and 2 aggregate data. For the primary endpoint individual data from 2000 patients were included, 994 randomized to clinically guided care and 1006 to NP-guided care. All-cause mortality was significantly reduced by NP-guided treatment [hazard ratio = 0.62 (0.45-0.86); P = 0.004] with no heterogeneity between studies or interaction with LVEF. The survival benefit from NP-guided therapy was seen in younger (= 75 years) patients [0.98 (0.75-1.27); P = 0.96]. Hospitalization due to heart failure [0.80 (0.67-0.94); P = 0.009] or cardiovascular disease [0.82 (0.67-0.99); P = 0.048] was significantly lower in NP-guided patients with no heterogeneity between studies and no interaction with age or LVEF. Conclusion Natriuretic peptide-guided treatment of heart failure reduces all-cause mortality in patients aged

The aim of this study was to analyze the prognostic value and attainability of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in young and elderly acute decompensated heart failure (ADHF) patients. Less-effective NT-proBNP-guided therapy in chronic heart failure (HF) has been reported in elderly patients. Whether this can be attributed to differences in prognostic value of NT-proBNP or to differences in attaining a prognostic value is unclear. The authors studied this question in ADHF patients. Our study population comprised 7 ADHF cohorts. We defined absolute ( 30%, >50%, and >70%). Six-month all-cause mortality after discharge was studied for each level in Cox regression analyses, and compared between elderly (age >75 years) and young patients (age ≤75 years). Thereafter, we compared percentages of elderly and young patients attaining NT-proBNP levels (= attainability). A total of 1,235 patients (59% male, 45% >75 years of age) was studied. Admission levels of NT-proBNP were significantly higher in elderly versus younger patients. The prognostic value of absolute and relative NT-proBNP levels was similar in elderly and young patients. Attainability was significantly lower in elderly patients for all absolute levels and a >50% relative reduction, but not for >30% and >70%. For absolute levels, attainability differences between age groups were decreased to a large extent after correction for admission NT-proBNP and anemia at discharge. For relative levels, attainability differences disappeared after correction for HF etiology and anemia at discharge. In young and elderly ADHF patients, it is not the prognostic value of absolute and relative NT-proBNP levels that is different, but the attainability of these levels that is lower in the elderly. This can largely be attributed to factors other than age

Objectives The study aim was to determine the prognostic value of a multimarker strategy for risk-assessment in patients presenting to the emergency department (ED) with dyspnea. Background Combining biomarkers with different pathophysiological backgrounds may improve risk stratification in dyspneic patients in the ED. Methods The study prospectively investigated the prognostic value of the biomarkers N-terminal pro–B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT), Cystatin-C (Cys-C), high-sensitivity C-reactive protein (hs-CRP), and Galectin-3 (Gal-3) for 90-day mortality in 603 patients presenting to the ED with dyspnea as primary complaint. Results hs-CRP, hs-cTnT, Cyst-C, and NT-proBNP were independent predictors of 90-day mortality. The number of elevated biomarkers was highly associated with outcome (odds ratio: 2.94 per biomarker, 95% confidence interval [CI]: 2.29 to 3.78, p Conclusions A multimarker strategy provided superior risk stratification beyond any single-marker approach. The MARKED-risk score that incorporates hs-cTnT, hs-CRP, and Cys-C along with clinical risk factors accurately identifies patients with very low, intermediate, and high risk.

Sudden cardiac arrest (SCA), due mainly to coronary artery disease (CAD), is a leading cause of death. To identify electrocardiographic and clinical differences between patients with CAD with and without SCA, 87 victims of SCA with CAD were compared with 131 patients with CAD without SCA. Patients' latest routine electrocardiograms and clinical variables were compared. Patients with CAD with and without previous myocardial infarctions (MIs) were included. Patients with SCA had a higher incidence of echocardiographic evidence of left ventricular hypertrophy and/or heart failure than controls. The median left ventricular ejection fractions for patients with SCA with and without previous MIs were 0.30 (interquartile range 0.24 to 0.41) and 0.41 (interquartile range 0.25 to 0.56). The median time between the last electrocardiographic assessment and SCA was 59 days (interquartile range 29 to 137). Regarding electrocardiographic characteristics, in patients with and without previous MIs, QRS width (odds ratio 1.032, 95% confidence interval 1.012 to 1.053, p = 0.002, and odds ratio 1.035, 95% confidence interval 1.015 to 1.056, p = 0.001) was the only significant predictor of SCA. In conclusion, in patients with CAD, regardless of a previous MI, a longer QRS width and echocardiographic parameters consistent with heart failure are associated with SCA, even in patients with ischemic cardiomyopathy currently not eligible for an implantable cardioverter-defibrillator.

BACKGROUND Cardiac troponin T measured by a high-sensitivity assay (hs-cTnT) recently proved to be of prognostic value in several populations. The hs-cTnT assay may also improve risk stratification in acute dyspnea. METHODS We prospectively studied the prognostic value of hs-cTnT in 678 consecutive patients presenting to the emergency department with acute dyspnea. On the basis of conventional cardiac troponin T assay (cTnT) and hs-cTnT assay measurements, patients were divided into 3 categories: (1) neither assay increased (cTnT RESULTS One hundred seventy-two patients were in the lowest, 282 patients in the middle, and 223 patients in the highest troponin category. Patients in the second and third categories had significantly higher mortality compared to those in the first category (90-day mortality rate 2%, 10%, and 26% in groups 1, 2, and 3, respectively, P < 0.001; 1-year mortality rate 9%, 21%, and 39%, P < 0.001). Importantly, in patients with undetectable cTnT (n = 347, 51%), increased hs-cTnT indicated worse outcome [90-day mortality, odds ratio 4.26 (95% CI 1.19–15.21); 1-year mortality, hazard ratio 2.27 (1.19–4.36), P = 0.013], whereas N-terminal pro–brain-type natriuretic peptide (NT-proBNP) was not predictive of short-term outcome. CONCLUSIONS hs-cTnT is associated with mortality in patients presenting with acute dyspnea. hs-cTnT concentrations provide additional prognostic information to cTnT and NT-proBNP testing in patients with cTnT concentrations below the detection limit. In particular, the hs-cTnT cutoff of 0.016 μg/L enables identification of low-risk patients.

Objectives The purpose of this study was to assess whether management of heart failure (HF) guided by an individualized N-terminal pro–B-type natriuretic peptide (NT-proBNP) target would lead to improved outcome compared with HF management guided by clinical assessment alone. Background Natriuretic peptides may be attractive biomarkers to guide management of heart failure (HF) and help select patients in need of more aggressive therapy. The PRIMA (Can PRo-brain-natriuretic peptide guided therapy of chronic heart failure IMprove heart fAilure morbidity and mortality?) study is, to our knowledge, the first large, prospective randomized study to address whether management of HF guided by an individualized target NT-proBNP level improves outcome. Methods A total of 345 patients hospitalized for decompensated, symptomatic HF with elevated NT-proBNP levels at admission were included. After discharge, patients were randomized to either clinically-guided outpatient management (n = 171), or management guided by an individually set NT-proBNP (n = 174) defined by the lowest level at discharge or 2 weeks thereafter. The primary end point was defined as number of days alive outside the hospital after index admission. Results HF management guided by this individualized NT-proBNP target increased the use of HF medication (p = 0.006), and 64% of HF-related events were preceded by an increase in NT-proBNP. Nevertheless, HF management guided by this individualized NT-proBNP target did not significantly improve the primary end point (685 vs. 664 days, p = 0.49), nor did it significantly improve any of the secondary end points. In the NT-proBNP–guided group mortality was lower, as 46 patients died (26.5%) versus 57 (33.3%) in the clinically-guided group, but this was not statistically significant (p = 0.206). Conclusions Serial NT-proBNP measurement and targeting to an individual NT-proBNP value did result in advanced detection of HF-related events and importantly influenced HF-therapy, but failed to provide significant clinical improvement in terms of mortality and morbidity.

Background Diagnostic biomarkers for heart failure (HF) such as the natriuretic peptides (NPs) are widely used but have limitations. Innovative biomarkers could provide improved diagnostic performance. Methods We launched a prospective case-control proteomic study and investigated for polypeptides specific to HF through a capillary electrophoresis-mass spectrometry (CE-MS) proteomic analysis. The putative biomarker was identified by Orbitrap liquid chromatography-MS, validated by western blot, then by ELISA using plasmas from multicentric international cohorts. A rat model of HF was tested for biomarker expression levels. Results We identified insulin like growth factor binding protein 2 (IGFBP2) as a new diagnostic biomarker for HF with a high sensitivity and specificity (AUC = 0.93; 95% CI, 0.89–0.96; P b 0.0001) in the local cohort and IGFBP2 levels provided an AUC of 0.943 (95% CI, 0.860–1.026) which gave a 87% sensitivity in AHF and 90% specificity at the cut off value previously determined in the discovery cohort, i.e. 556 ng/ml. ROC curve analysis of IGFBP2 and NTproBNP showed an AUC of 0.784 (95% CI, 0.744–0.820) for IGFBP2 and a significantly higher AUC of 0.927 (95% CI, 0.900–0.949) for NT-proBNP, P Conclusion IGFBP2 is a new biomarker to diagnose HF, which could be used to provide additional information to the NPs. Animals models, will help in the evaluation of the putative IGFBP2 regulated mechanisms in HF.

Objectives Our aim was to identify shortcomings in the management of patients with both atrial fibrillation (AF) and heart failure (HF). Background AF and HF often coincide in cardiology practice, and they are known to worsen each other's prognosis, but little is known about the quality of care of this combination. Methods In the observational Euro Heart Survey on AF, 5,333 AF patients were enrolled in 182 centers across 35 European Society of Cardiology member countries in 2003 and 2004. A follow-up survey was performed after 1 year. Results At baseline, 1,816 patients (34%) had HF. Recommended therapy for HF with left ventricular systolic dysfunction (LVSD) with a beta-blocker and either an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker was prescribed in 40% of HF patients, while 29% received the recommended drug therapy for both LVSD-HF and AF, consisting of the combination of a beta-blocker, either ACEI or angiotensin II receptor blocker, and oral anticoagulation. Rate control was insufficient with 40% of all HF patients with permanent AF having a heart rate ≤80 beats/min. In the total cohort, HF patients had a higher risk for mortality (9.5% vs. 3.3%; p Conclusions The prescription rate of guideline-recommended drug therapy for AF and LVSD-HF is low. Randomized controlled trials targeting this highly prevalent subgroup with AF and HF are warranted.

Atrial fibrillation (AF) is an obstinate and widespread arrhythmia with multiple presentations and potential for hazardous consequences. Although our knowledge of AF is advancing, the onset and progression of AF and the interaction with its many associated diseases is not fully understood. Also, management recommendations on evidence based issues are frequently ignored for a wide range of reasons. The following developments are expected to improve efficacy, safety, and guideline adherence regarding the management of AF: earlier detection of AF, improved understanding and management of its associated diseases, adequate rate-control targets, more effective and safer rhythm control measures, an easy-to-use risk stratification scheme incorporating both risk factors for stroke and major bleeding to tailor antithrombotic treatment, and anticoagulation drugs not requiring monitoring of the international normalized ratio. Translational researchers, clinical trialists, and epidemiologists should complement each other to fulfil the current needs in the management of AF and to monitor whether there are solutions for existing ‘undecided issues’ and new ones are developing.

Background Limited data exist for the role of serum potassium changes during hospitalization for acute decompensated heart failure (ADHF). The present study investigated the long-term prognostic value of potassium changes during hospitalization in patients admitted for ADHF. Methods Our study is a pooled individual patient data analysis assembled from 3 prospective cohorts comprising 754 patients hospitalized for ADHF. The endpoint was all-cause mortality within 180 days after discharge. Serum potassium levels and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were measured at admission and at discharge. Results A percentage decrease >15% in serum potassium levels occurred in 96 (13%) patients, and an absolute decrease of >0.7 mmol/L in serum potassium levels occurred in 85 (12%) patients; and both were predictors of poor outcome independent of admission or discharge serum potassium. After the addition of other strong predictors of mortality-a 30% change in NT-proBNP during hospitalization, discharge levels of NT-proBNP, renal markers, and other relevant clinical variables-the multivariate hazard ratio of serum potassium percentage reduction of >15% remained an independent predictor of 180-day mortality (hazard ratio 2.06, 95% CI 1.14-3.73). Conclusions A percentage serum potassium decline of >15% is an independent predictor of 180-day all-cause mortality on top of baseline potassium levels, NT-proBNP levels, renal variables, and other relevant clinical variables. This suggest that patients hospitalized for ADHF with a decline of >15% in serum potassium levels are at risk and thus monitoring and regulating of serum potassium level during hospitalization are needed in these patients.

OBJECTIVE: The aim of this work was to assess the prognostic value of absolute N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentration in combination with changes during admission because of acute heart failure (AHF) and early after hospital discharge.BACKGROUND: In AHF, readmission and mortality rates are high. Identifying those at highest risk for events early after hospital discharge might help to select patients in need of intensive outpatient monitoring.METHODS AND RESULTS: We evaluated the prognostic value of NT-proBNP concentration on admission, at discharge, 1 month after hospital discharge and change over time in 309 patients included in the PRIMA (Can PRo-brain-natriuretic peptide guided therapy of chronic heart failure IMprove heart fAilure morbidity and mortality?) study. Primary outcome measures were mortality and the combined end point of heart failure (HF) readmission or mortality. In a multivariate Cox regression analysis, change in NT-proBNP concentration during admission, change from discharge to 1 month after discharge, and the absolute NT-proBNP concentration at 1 month after discharge were of independent prognostic value for both end points (hazard ratios for HF readmission or mortality: 1.71, 95% confidence interval [CI] 1.13-2.60, Wald 6.4 [P = .011] versus 2.71, 95% CI 1.76-4.17, Wald 20.5 [P < .001] versus 1.81, 95% CI 1.13-2.89, Wald 6.1 [P = .014], respectively.CONCLUSIONS: Knowledge of change in NT-proBNP concentration during admission because of AHF in combination with change early after discharge and the absolute NT-proBNP concentration at 1 month after discharge allows accurate risk stratification.

trabeculations in the ventricular apex because it is a real-time imaging method and by moving slightly the imaging plane we can see if the trabeculations end in chordae tendinea inserting on the mitral valve or only protrude into the left ventricular cavity without a connection to the mitral apparatus. One has to be very careful in order not to over-diagnose LVHT, like pointed out by the authors. Since there are no anatomically controlled studies comparing CMRI with autoptic or surgical findings there is a lack of diagnostic criteria for LVHT by CMRI [5]. Furthermore, we don't agree that LVHT leads to a dilated cardiomyopathy. LVHT occurs in dilated as well as in normally sized ventricles [6]. Only some of the patients develop systolic dysfunction or left ventricular dilation. Since LVHT occurs familiarly it would be interesting to know if relatives of the patients were investigated and which were they results? Did any of the close relatives also present with LVHT, other cardiac disease or neurological disease? Since the etiology and pathogenesis of LVHT is unclear it is desirable to describe in more details the history of the patient, the family history and the clinical findings in this patient including extra-cardiac co-morbidities. Since LVHT is frequently associated with neuromuscular disorders or chromosomal abnormalities the patients should be investigated by a neurologist and by a geneticist. Was there any indication for such a disorder according the authors impression? Were muscle enzymes elevated in this patient? Was the family history positive for muscle disease? When diagnosing LVHT investigate the patient and his relatives for other cardiac disease, any neuromuscular disorder, and for chromosomal defects. There is no need for a specific LVHT therapy. Treat additional cardiac abnormalities as usual. The authors of this manuscript have certified that they comply with the Principles of Ethical Publishing in the International Journal of Cardiology [7].

The study aim was to determine the prognostic value of a multimarker strategy for risk-assessment in patients presenting to the emergency department (ED) with dyspnea.Combining biomarkers with different pathophysiological backgrounds may improve risk stratification in dyspneic patients in the ED.The study prospectively investigated the prognostic value of the biomarkers N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT), Cystatin-C (Cys-C), high-sensitivity C-reactive protein (hs-CRP), and Galectin-3 (Gal-3) for 90-day mortality in 603 patients presenting to the ED with dyspnea as primary complaint.hs-CRP, hs-cTnT, Cyst-C, and NT-proBNP were independent predictors of 90-day mortality. The number of elevated biomarkers was highly associated with outcome (odds ratio: 2.94 per biomarker, 95% confidence interval [CI]: 2.29 to 3.78, p0.001). A multimarker approach had incremental value beyond a single-marker approach. Our multimarker emergency dyspnea-risk score (MARKED-risk score) incorporating age ≥75 years, systolic blood pressure110 mm Hg, history of heart failure, dyspnea New York Heart Association functional class IV, hs-cTnT ≥0.04 μg/l, hs-CRP ≥25 mg/l, and Cys-C ≥1.125 mg/l had excellent prognostic performance (area under the curve: 0.85, 95% CI: 0.81 to 0.89), was robust in internal validation analyses and could identify patients with very low (3 points), intermediate (≥3,5 points), and high risk (≥5 points) of 90-day mortality (2%, 14%, and 44% respectively; p0.001).A multimarker strategy provided superior risk stratification beyond any single-marker approach. The MARKED-risk score that incorporates hs-cTnT, hs-CRP, and Cys-C along with clinical risk factors accurately identifies patients with very low, intermediate, and high risk.

Background Parvovirus B19 (PVB19) persistence in the heart has been associated with progressive cardiac dysfunction and evolution to dilated cardiomyopathy. In the present study, we investigated whether immunomodulation with intravenous immunoglobulin (IVIg) in addition to conventional heart failure therapy is safe and achieves virus reduction. Such therapy might improve cardiac function in patients with chronic dilated cardiomyopathy (DCM) and a significant PVB19 viral load in the heart. Methods PVB19 viral load was studied in 25 post-mortem cardiac samples of patients with a normal heart. Then, 17 consecutive patients (mean age 53 ±3 years) with DCM and symptomatic heart failure for >1 year with a PVB19 viral load in endomyocardial biopsies of >250 copies/μg DNA were treated with a high dose of IVIg (2 g/kg). Results The post-mortem cardiac samples revealed a PVB19 presence in 80% with a mean load of 131 ±40 copies/μg DNA. In the treated patients, IVIg resulted in a significant decrease of PVB19 viral load from 1,420 ±216 to 619 ±200 copies/μg DNA ( P=0.004) and significantly improved the ejection fraction from 33 ±3% 6 months before treatment and 34 ±3% at baseline to 41 ±3% 6 months ( P=0.001) after IVIg therapy. The New York Heart Association classification significantly improved from 2.5 ±0.1 at baseline to 2.1 ±0.1 at follow-up ( P=0.004). No therapy-related complications were noted. Conclusion The present pilot study demonstrates that IVIg significantly reduces viral load and improves cardiac function in patients with DCM related to increased PVB19 viral load in the heart.

Isolated left ventricular non-compaction (LVNC), also known as left ventricular hypertrabeculation, is characterized by the presence of extensive myocardial trabeculation and deep intertrabecular recesses that communicate with the left ventricular cavity. It potentially leads to progressive cardiac failure, thromboembolism, and malignant cardiac arrhythmias. We describe a case of a heart failure patient with diagnostic criteria of LVNC that became less clear after standard heart failure treatment.

Giant cell myocarditis (GCM) is an uncommon inflammatory heart disease with a rapid progression and a devastating outcome. Its exact cause is unknown, but it has been associated with various inflammatory and autoimmune disorders. The authors report a case where GCM is triggered by a parvovirus B19 (PVB19) infection.
