- 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.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Anaemia may affect B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) levels, but this has not been well described in heart failure (HF) patients without the exclusion of patients with renal dysfunction. AIMS: To study the influence of both anaemia and renal function on BNP and NT-proBNP levels in a large group of hospitalised HF patients. METHODS AND RESULTS: We studied 541 patients hospitalised for HF (mean age 71+/-11 years, 62% male, and left ventricular ejection fraction 0.33+/-0.14). Of these patients, 30% (n=159) were anaemic (women: Hb<7.5 mmol/l, men: Hb<8.1 mmol/l). Of the 159 anaemic patients, 73% had renal dysfunction (eGFR<60 ml/min/1.73 m2) and of the non-anaemic patients, 57% had renal dysfunction. BNP and NT-proBNP levels were measured in all patients before discharge. In multivariable analyses both plasma haemoglobin and eGFR were independently related to the levels of BNP and NT-proBNP (standardised beta's of -0.16, -0.14 [BNP] and -0.19, -0.26 [NT-proBNP] respectively, P-values<0.01). CONCLUSION: Anaemia and renal dysfunction are related to increased BNP and NT-proBNP levels, independent of the severity of HF. These results indicate that both anaemia and renal dysfunction should be taken into consideration during the interpretation of BNP and NT-proBNP levels in HF patients.

- BACKGROUND: B-type natriuretic peptide (BNP) and 6-min walk test (6MWT) are both related to the severity and prognosis in chronic heart failure (CHF), but may reflect different aspects of CHF. We related BNP and 6MWT to left ventricular ejection fraction (LVEF), New York Heart Association functional class (NYHA), and two indices of quality of life (physical subscales): the Minnesota Living with Heart Failure Questionnaire (MLwHFQph) and the RAND-36ph. METHODS: Plasma BNP and 6MWT were measured at discharge in 229 patients who had been admitted for CHF. LVEF and NYHA were determined, and patients completed the MLwHFQ and RAND-36 questionnaires. RESULTS: BNP was weakly correlated to LVEF (r=-0.29, P<0.01) and NYHA (r=0.20, P<0.01), but not to MLwHFQph and RAND-36ph. On the other hand, 6MWT is related to MLwHFQph (r=-0.23, P<0.01), RAND-36ph (r=0.52, P<0.01), and NYHA (r=-0.46, P<0.01), but not to LVEF (r=-0.15, P=0.05). There is also no correlation between BNP and 6MWT (r=-0.01, P=0.87). CONCLUSIONS: The present data show that BNP and 6MWT represent different aspects of the clinical syndrome of CHF. The outcomes of this study suggest that BNP plasma levels are more related to cardiac function, while 6MWT reflects functional capacity and quality of life.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Natriuretic peptides are currently used in the diagnosis and follow-up of patients with Chronic Heart Failure (CHF). However, it is unknown whether there are different influences of age on atrial natriuretic peptide (ANP)/N-terminal-ANP (NT-ANP) or B-type natriuretic peptide (BNP)/N-terminal-proBNP (NT-proBNP). AIMS: To compare the influence of age and gender on plasma levels of ANP/NT-ANP and BNP/NT-proBNP in CHF patients. METHODS AND RESULTS: Natriuretic peptides were measured in 311 CHF patients (68+/-8 years, 76% males, left ventricular ejection fraction (LVEF) 0.23+/-0.08). All natriuretic peptides were significantly related to age (p<0.05) on multivariate regression analysis, with partial correlation coefficients of 0.18, 0.29, 0.28 and 0.25 for ANP, NT-ANP, BNP and NT-proBNP, respectively. The relative increase of both BNP/NT-proBNP were more pronounced than of ANP/NT-ANP (p<0.01). Furthermore, the relative increase of BNP with age was markedly larger than of NT-proBNP (p<0.01). Levels of all natriuretic peptides were also significantly related to cardiothoracic ratio, renal function and LVEF. CONCLUSION: In patients with CHF, BNP/NT-proBNP were more related to age than ANP/NT-ANP, and BNP was more related to age than NT-proBNP. However, in these CHF patients the influence of age on the levels of all natriuretic peptides was modest, and comparable to several other factors.

- BACKGROUND: In patients with acute heart failure (HF) presenting at the emergency department, a B-type natriuretic peptide (BNP) level < 100 pg/mL was found in only 10% of the patients. However, in a more stable outpatient HF population from another study, a BNP level < 100 pg/mL was found in as many as 21% of the patients. Therefore, we aimed to investigate the prevalence and characteristics of stabilized patients with BNP levels < 100 pg/mL before discharge after admission for decompensated heart failure HF. METHODS: We investigated 601 patients with HF who were part of a large-scale multicenter study in The Netherlands. All patients had been admitted for decompensated HF, and their BNP levels were measured before discharge when they had been clinically stabilized. Clinical characteristics of patients with BNP levels < 100 and > or = 100 pg/mL were compared. RESULTS: Patients were 70 +/- 12 years old, 61% were men, and mean left ventricular ejection fraction was 0.34 +/- 0.14. Of these patients, 10% had BNP levels < 100 pg/mL. Patients with a BNP level < 100 pg/mL were similar in age and sex but had higher left ventricular ejection fraction (0.41 +/- 0.14 vs 0.33 +/- 0.13, P < .001), body mass index, and hemoglobin and hematocrit concentrations compared with those with BNP levels > or = 100 pg/mL. CONCLUSIONS: In clinically stable patients with a recent admission for decompensated HF, only 10% had BNP levels > or = 100 pg/mL. These patients with low BNP levels seemed to have less severe HF and more frequently had preserved systolic function compared with patients with BNP levels > or = 100 pg/mL.

- OBJECTIVES: Our aim was to study the possible role of depressive symptoms in the effectiveness of a disease management program (DMP) in heart failure (HF) patients. BACKGROUND: Disease management programs are recommended in current HF guidelines, but certain patient groups, such as those with depression, might be less responsive to such programs. METHODS: From the data of a large multicenter study, in which we examined the effect of a DMP in HF patients, we investigated a potential interaction between depressive symptoms at baseline and the effect of such a program. RESULTS: Of the 958 HF patients (37% female; age 71 +/- 11 years; New York Heart Association functional class II to IV), 377 (39%) reported depressive symptoms at baseline. During 18 months of follow-up, the primary end point (composite of all-cause mortality and HF readmission) occurred in 39% of the nondepressed patients and 42% of depressed patients. In the overall sample, there was no significant effect of DMP on the composite primary end point. The effect of the DMP was significantly different in nondepressed than in depressed HF patients. A significant effect modification by depressive symptoms was observed in evaluating the effect of the DMP on all-cause mortality and HF readmission (p = 0.03). In patients without depressive symptoms, DMP resulted in a trend for lower incidence of the primary end point (hazard ratio: 0.8, 95% confidence interval: 0.61 to 1.04), whereas the reverse was observed in patients with depressive symptoms (hazard ratio: 1.3, 95% confidence interval: 0.95 to 1.98). CONCLUSIONS: Depressive symptoms in patients with HF have a major effect on the usefulness of DMP. Identification of depressive symptoms before enrollment in a DMP might lead to more accurate use of a DMP, because depressive patients might not benefit from a general program.

- Background It is unclear how depressive symptoms in patients with heart failure developover time and whether this trajectory of depressive symptoms is associated with hospital admission and prognosis.Aim To describe the time-course of depressive symptoms and determine the relationship with hospital admission and mortality.Method Data was analysed using 611 patients with completed CES-D questionnaires at baseline and at 18 months. Data on hospital readmission was collected 18 months after discharge and data on mortality was collected 18 and 36 months post-discharge.Results The prevalence of depressive symptoms was 38% (n=229) at discharge and 26% (n=160) after 18 months. A total of 140 (61%) of the 229 patients with depressive symptoms at discharge had recovered from depressive symptoms after 18 months whereas 71 (18%) of the 382 non-depressed developed depressive symptoms and 89 (39%) of the 229 depressed remained depressed. Depressive symptoms at discharge were not associated with mortality after 18 months but patients with recently (i.e. during 18 months) developed depressive symptoms showed a significantly higher risk for cardiovascular readmissions (HR 1.7, p=0.016). After 36 months, patients with developed depressive symptoms after discharge were at a higher risk of all-cause mortality (HR 2.0, p=0.012) and there was a trend towards a higher risk of all-cause mortality in patients with ongoing depressive symptoms (HR 1.7, p=0.056).Conclusion A significant proportion of patients with HF, who were reported depressive symptoms at discharge recovered from depressive symptoms during the following 18 months. However, patients who remained having depressive symptoms or patients who developed depressive symptoms had a worse prognosis.

- 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: Knowledge of patient preferences is vital for delivering optimal healthcare. This study uses utility measurement to assess the preferences of heart failure (HF) patients regarding quality of life or longevity. The utility approach represents the perspective of a patient; facilitates the combination of mortality, morbidity, and treatment regimen into a single score; and makes it possible to compare the effects of different interventions in healthcare.METHODS AND RESULTS: Patient preferences of 100 patients with HF were assessed in interviews using the time trade-off (TTO) approach. Health-related quality of life (HR-QoL) was assessed with the EQ-5D and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Patients' own estimation of life expectancy was assessed with a visual analogue scale (VAS). Of the 100 patients (mean age 70 ± 9 years; 71% male), 61% attach more weight to quality of life over longevity; while 9% and 14% were willing to trade 6 and 12 months, respectively, for perfect health and attach more weight to quality of life. Patients willing to trade time had a significantly higher level of NT-proBNP and reported significantly more dyspnoea during exertion. Predictors of willingness to trade time were higher NT-proBNP and lower EQ VAS.CONCLUSION: The majority of HF patients attach more weight to quality of life over longevity. There was no difference between both groups with respect to life expectancy described by the patients. These insights enable open and personalized discussions of patients' preferences in treatment and care decisions, and could guide the future development of more patient-centred care.
