Background: Chronic heart failure (CHF) is a severe condition, often co-occurring with depression and anxiety, that strongly affects the quality of life (QoL) in some patients. Conversely, depressive and anxiety symptoms are associated with a 2–3 fold increase in mortality risk and were shown to act independently of typical risk factors in CHF progression. The aim of this study was to examine the impact of depression, anxiety, and QoL on the occurrence of rehospitalization within one year after discharge in CHF patients. Methods: 148 CHF patients were enrolled in a 10-center, prospective, observational study. All patients completed two questionnaires, the Hospital Anxiety and Depression Scale (HADS) and the Questionnaire Short Form Health Survey 36 (SF-36) at discharge timepoint. Results: It was found that demographic and clinical characteristics are not associated with rehospitalization. Still, the levels of depression correlated with gender (p ≤ 0.027) and marital status (p ≤ 0.001), while the anxiety values ​​were dependent on the occurrence of chronic obstructive pulmonary disease (COPD). However, levels of depression (HADS-Depression) and anxiety (HADS-Anxiety) did not correlate with the risk of rehospitalization. Univariate logistic regression analysis results showed that rehospitalized patients had significantly lower levels of Bodily pain (BP, p = 0.014), Vitality (VT, p = 0.005), Social Functioning (SF, p = 0.007), and General Health (GH, p = 0.002). In the multivariate model, poor GH (OR 0.966, p = 0.005) remained a significant risk factor for rehospitalization, and poor General Health is singled out as the most reliable prognostic parameter for rehospitalization (AUC = 0.665, P = 0.002). Conclusion: Taken together, our results suggest that QoL assessment complements clinical prognostic markers to identify CHF patients at high risk for adverse events.

Aims: In heart failure, various biomarkers are established for diagnosis and risk stratification; however, little is known about the relevance of serial measurements during an episode worsening heart failure (WHF). This study sought to investigate the trajectory of natriuretic peptides and multiple novel biomarkers during hospitalization for WHF and to determine the best time point to predict outcome. Methods and results: MOLITOR (Impact of Therapy Optimisation on the Level of Biomarkers in Patients with Acute and Decompensated Chronic Heart Failure) was an eight-centre prospective study of 164 patients hospitalized with a primary diagnosis of WHF. C-terminal fragment of pre-pro-vasopressin (copeptin), N-terminal pro-B-type natriuretic peptide (NT-proBNP), mid-regional pro-atrial natriuretic peptide (MR-proANP), mid-regional pro-adrenomedullin (MR-proADM), and C-terminal pro-endothelin-1 (CT-proET1) were measured on admission, after 24, 48, and 72 h, and every 72 h thereafter, at discharge and follow-up visits. Their performance to predict all-cause mortality and rehospitalization at 90 days was compared. All biomarkers decreased during recompensation (P < 0.05) except MR-proADM. Copeptin at admission was the best predictor of 90 day mortality or rehospitalization (χ2 = 16.63, C-index = 0.724, P < 0.001), followed by NT-proBNP (χ2 = 10.53, C-index = 0.646, P = 0.001), MR-proADM (χ2 = 9.29, C-index = 0.686, P = 0.002), MR-proANP (χ2 = 8.75, C-index = 0.631, P = 0.003), and CT-proET1 (χ2 = 6.60, C-index = 0.64, P = 0.010). Re-measurement of copeptin at 72 h and of NT-proBNP at 48 h increased prognostic value (χ2 = 23.48, C-index = 0.718, P = 0.00001; χ2 = 14.23, C-index = 0.650, P = 0.00081, respectively). Conclusions: This largest sample of serial measurements of multiple biomarkers in WHF found copeptin at admission with re-measurement at 72 h to be the best predictor of 90 day mortality and rehospitalization. © 2018 The Authors.

Background: Elevated C-reactive protein (CRP) is associated with adverse outcomes in heart failure (HF) patients. Beta-blocker therapy may lower CRP levels. Methods and results: To assess if the changes of high-sensitivity (hs) CRP levels in HF patients over 12-week titration with beta-blockers correlate with functional capacity, plasma hs-CRP levels were measured in 488 HF patients [72.1 ± 5.31 years, LVEF 40% (33/50)]. Hs-CRP, NT-proBNP and 6-min-walk-test (6MWT) were assessed at baseline and at week 12. Patients were divided based on hs-CRP changes (cut-off > 0.3 mg/dl) into low–low (N = 225), high–high (N = 132), low–high (N = 54), high–low (N = 77) groups. At baseline, median hs-CRP concentration was 0.25 (0.12/0.53) mg/dl, NT-proBNP 551 (235/1455) pg/ml and average 6MWT distance 334 ± 105 m. NT-proBNP changes were significantly different between the four hs-CRP groups (P = 0.011). NT-proBNP increased in the low–high group by 30 (− 14/88) pg/ml and decreased in the high–low group by − 8 (− 42/32) pg/ml. 6MWT changes significantly differed between groups [P = 0.002; decrease in the low–high group (− 18 ± 90 m) and improvement in the low–low group (24 ± 62 m)]. Conclusion: After beta-blocker treatment, hs-CRP levels are associated with functional capacity in HF patients. Whether this represents a potential target for intervention needs further study. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.

Objectives: This study evaluated the tolerability and feasibility of titration of 2 distinctly acting beta-blockers (BB) in elderly heart failure patients with preserved (HFpEF) and reduced (HFrEF) left ventricular ejection fraction. Background: Broad evidence supports the use of BB in HFrEF, whereas the evidence for beta blockade in HFpEF is uncertain. Methods: In the CIBIS-ELD (Cardiac Insufficiency Bisoprolol Study in Elderly) trial, patients >65 years of age with HFrEF (n = 626) or HFpEF (n = 250) were randomized to bisoprolol or carvedilol. Both BB were up-titrated to the target or maximum tolerated dose. Follow-up was performed after 12 weeks. HFrEF and HFpEF patients were compared regarding tolerability and clinical effects (heart rate, blood pressure, systolic and diastolic functions, New York Heart Association functional class, 6-minute-walk distance, quality of life, and N-terminal pro-B-type natriuretic peptide). Results: For both of the BBs, tolerability and daily dose at 12 weeks were similar. HFpEF patients demonstrated higher rates of dose escalation delays and treatment-related side effects. Similar HR reductions were observed in both groups (HFpEF: 6.6 beats/min; HFrEF: 6.9 beats/min, p = NS), whereas greater improvement in NYHA functional class was observed in HFrEF (HFpEF: 23% vs. HFrEF: 34%, p < 0.001). Mean E/e' and left atrial volume index did not change in either group, although E/A increased in HFpEF. Conclusions: BB tolerability was comparable between HFrEF and HFpEF. Relevant reductions of HR and blood pressure occurred in both groups. However, only HFrEF patients experienced considerable improvements in clinical parameters and left ventricular function. Interestingly, beta-blockade had no effect on established and prognostic markers of diastolic function in either group. Long-term studies using modern diagnostic criteria for HFpEF are urgently needed to establish whether BB therapy exerts significant clinical benefit in HFpEF.
