- Background: Physical activity and appetite are important for maintaining physical health. Yet, sedentary lifestyle and poor appetite are frequently observed in the heart failure (HF) population. However, the relationships between these phenomena are not yet clearly understood. Purpose: To investigate the relationship between physical activity and appetite in patients with stable HF.Methods: In this cross sectional study, a consecutive sample of 186 patients with confirmed HF with NYHA class II-IV (median age 72y, 70% men, NYHA class II 61%) participated in the study. Patients were recruited from three HF outpatient clinics in central Sweden. Physical activity measures included total energy expenditure (TEE), active energy expenditure (AEE) above 3 METs, average daily METs and number of steps per day during four days using a validated multi-sensor wearable armband (SenseWear®, Body Monitoring System). Patients also self-reported their physical activity on a ten point numeric rating scale, from extremely low (1) to extremely high (10). Self-reported appetite was measured by Council on Nutrition Appetite Questionnaire (CNAQ), an 8-item instrument (score range 8-40) where CNAQ ≤28 indicate poor appetite. Associations between physical activity and appetite were analyzed by Spearman correlation while differences in physical activity between poor vs good appetite were analyzed using Mann Whitney U test.Results: There was a significant positive relationship between physical activity and appetite assessed by TEE (rs=.184, p=.012), AEE of moderate intensity >3 METs (rs=.262, p=.000), number of steps (rs=.292, p=.000), average METs intensity (rs=.249, p=.001), and self- reported physical activity (rs=.191, p =.009). Levels of physical activity in the low appetite group differed significantly from the group with better appetite, this was seen in all physical dimensions, TEE (U=3225, z=-2.26, p=.024), AEE (U=2902, z=-3.178, p=.001), number of steps (U=2706, z=-3.734, p=.000), average METs intensity (U=3128, z=-2.541, p=.011), levels of self-reported physical activity (U=3185, z=-2.47, p=.013).Conclusion: This study shows that physical activity is associated with appetite and that levels of physical activity differs between patients with poor and good appetite. These findings has implications for both research and practice and underlines the importance in monitoring both physical activity and appetite. Further research is needed to determine whether interventions targeting physical activity also improve appetite and vice versa in the HF population.

- AimsTo investigate the relationship between angina pectoris and fatal and non-fatal clinical outcomes in heart failure with reduced and preserved ejection fraction (HF-REF and HF-PEF, respectively). Methods and resultsOf 7599 patients in the CHARM program, 5408 had ischaemic heart disease; 3855 had HF-REF (ejection fraction 45%) and 1553 had HF-PEF. These patients were separated into three groups: no history of angina, previous angina, and current angina. Three coronary outcomes were examined: fatal or non-fatal myocardial infarction (MI); MI or hospitalization for unstable angina (UA); and MI, UA or coronary revascularization. The composite heart failure outcome of cardiovascular death or heart failure hospitalization (HFH) was also analysed, along with its components and all-cause mortality. New York Heart Association functional class was worse in both HF-REF and HF-PEF patients with current angina compared with patients without angina (P<0.001 and P=0.005 respectively), despite similar clinical examination findings and ejection fraction. Patients with current angina had a higher risk of all three coronary outcomes (adjusted hazard ratios ranging from 1.8-3.1) than those without angina but did not have a higher risk of heart failure outcomes or all-cause mortality. ConclusionIn patients with heart failure current angina is associated with significantly more functional limitation and a higher risk of coronary events, across the spectrum of left ventricular ejection fraction.

- Background and Aim: Left atrial (LA) enlargement is associated with atrial fibrillation (AF) incidence and outcome. Trans-catheter ablation of AF has now become a conventional treatment of AF but its recurrence remains of clinical significance. The predictive role of the LA size in AF treatment is still controversial, hence the aim of this meta-analysis was to analyze the potential association between LA diameter and AF recurrence after ablation.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to December 2016 in order to select clinical trial and observational studies, which assessed the predictive role of LA diameter in AF recurrence after catheter-ablation. 13.573 patients from 61 studies with paroxysmal AF (PAF), persistent (PeAF) or longstanding persistent AF (L-PeAF) were included.Results: The pooled analysis showed that after a follow-up period of 19± 7.74 months, patients with AF recurrence had larger LA size compared with those without AF recurrence, with a weighted mean difference (WMD) 0.49 ([95% CI 0.39 to 0.59], P < 0.001), irrespective of the type of AF. A subgroup analysis showed LA diameter to be different; WMD was 2.29 ([95% CI 1.31 to 3.26], P < 0.001) in PAF and 1.51 ([95% CI 1.10 to 1.93], P < 0.001) in PeAF/L-PeAF, the difference between these two subgroups was not significant (Chi2=2.04, I2=51.1%, p=0.15). LA diameter ≥40 mm predicted AF recurrence HR:1.08 [95% CI 1.03 to 1.14], P=0.006), but the best cut-off value, in all included patients, was ≥50mm HR:2.73 [95% CI 1.64 to 4.55], P<0.001).Conclusions: Increased LA diameter significantly predicts recurrence of AF after ablation procedure. While a diameter of 40 mm predicts recurrence, a diameter more than 50 mm is the most accurate predictor.

- Background and Aim: Despite the improved outcome of patients with atrial fibrillation (AF) who undergo catheter ablation, recurrence of the arrhythmia remains a concern. The aim of this meta-analysis was to assess the potential association between left atrial (LA) strain and AF recurrence after ablation.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to December 2016 in order to identify clinical trial and observational studies, which assessed the predictive role of LA strain in AF recurrence after catheter-ablation. The search identified 898 patients form 10 studies, with paroxysmal AF (PAF) and persistent AF (PeAF).Results: The pooled analysis showed that after a follow-up period of 11.8± 8.1 months, patients with AF recurrence had reduced LA strain compared with those without AF, with a weighted mean difference (WMD) -7.04% ([95% CI -9.62 to -4.45], P < 0.0001). A subgroup analysis showed that LA strain was reduced regardless of AF type; WMD was -5.47% ([95% CI -9.82% to -1.13%], P=0.003) in PAF and -7.88% ([95% CI -11.19% to -4.56%], P < 0.001) in PAF/PeAF, the difference between these two subgroups was not significant (Chi2=0.75, I2=0.0%, p=0.39). A cut off value of 21% [6% to 30%], was 79% [65-86%] sensitive and 77% [66% to 91%] specific for predicting AF recurrence.Conclusions: Reduced LA strain significantly predicts recurrence of AF after ablation procedure, irrespective of AF type. This emphasizes the impact of LA wall remodeling on successful ablation.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aim: Quality of life is as important as survival in heart failure (HF) patients. Controversies exist with regards to echocardiographic predictors of exercise capacity in HF, particularly in patients with preserved ejection fraction (HFpEF). The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional exercise capacity assessed by 6 min walk test (6-MWT) in patients with HFpEF.Methods: In 111 HF patients (mean age 63± 10 years, 47% female), an echo-Doppler study and a 6-MWT were performed in the same day. Patients were divided into two groups based on the 6-MWT distance (Group I: ≤ 300 m and Group II: >300 m).Results: Group I were older (p=0.008), had higher prevalence of diabetes (p=0.027), higher baseline heart rate (p=0.004), larger left atrium - LA (p=0.001), longer LV filling time - FT (p=0.019), shorter isovolumic relaxation time (p=0.037), shorter pulmonary acceleration time - PAAT (p=0.006), lower left atrial lateral wall myocardial velocity (a’) (p=0.018) and lower septal systolic myocardial velocity (s’) (p=0.023), compared with Group II. Patients with HF and reduced EF (HFrEF) had lower hemoglobin (p=0.007), higher baseline heart rate (p=0.005), higher NT-ProBNP (p=0.001), larger LA (p=0.004), lower septal s’, e’, a’ waves, and septal MAPSE, shorter PAAT (p < 0.001 for all), lower lateral MAPSE, higher E/A & E/e’, and shorter LVFT (p=0.001 for all), lower lateral e’ (p=0.009), s’ (p=0.006), RV e’ and LA emptying fraction (p=0.012 for both), compared with HFpEF patients. In multivariate analysis, only LA diameter [2.676 (1.242-5.766), p=0.012], and diabetes [0.274 (0.084 - 0.898), p=0.033] independently predicted poor 6-MWT performance in the group as a whole. In HFrEF, age [1.073 (1.012 - 1.137), p=0.018] and LA diameter [3.685 (1.348 - 10.071), p=0.011], but in HFpEF, lateral s’ [0.295 (0.099 - 0.882), p=0.029], and hemoglobin level [0.497 (0.248-0.998), p=0.049] independently predicted poor 6-MWT performance.Conclusion: In HF patients predictors of exercise capacity differ according to severity of overall LV systolic function, with left atrial enlargement in HFrEF and longitudinal systolic shortening in HFpEF as the the main predictors.

- The use of an erythropoesis-stimulating agent, darbepoetin alfa (DA), to treat anaemia in patients with diabetes mellitus and chronic kidney disease was associated with a heightened risk of stroke and neutral efficacy in the Trial to Reduce Cardiovascular Events with Aranesp Therapy (TREAT), despite epidemiological data suggesting the contrary. However, this association has not been evaluated in another randomized, placebo-controlled trial.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: In heart failure (HF) with reduced ejection fraction and sinus rhythm, heart rate reduction with ivabradine reduces the composite incidence of cardiovascular death and HF hospitalization. METHODS AND RESULTS: It is unclear whether the duration of HF prior to therapy independently affects outcomes and whether it modifies the effect of heart rate reduction. In SHIFT, 6505 patients with chronic HF (left ventricular ejection fraction of /=70 b.p.m., treated with guideline-recommended therapies, were randomized to placebo or ivabradine. Outcomes and the treatment effect of ivabradine in patients with different durations of HF were examined. Prior to randomization, 1416 ivabradine and 1459 placebo patients had HF duration of >/=4 weeks and <1.5 years; 836 ivabradine and 806 placebo patients had HF duration of 1.5 years to <4 years, and 989 ivabradine and 999 placebo patients had HF duration of >/=4 years. Patients with longer duration of HF were older (62.5 years vs. 59.0 years; P < 0.0001), had more severe disease (New York Heart Association classes III/IV in 56% vs. 44.9%; P < 0.0001) and greater incidences of co-morbidities [myocardial infarction: 62.9% vs. 49.4% (P < 0.0001); renal dysfunction: 31.5% vs. 21.5% (P < 0.0001); peripheral artery disease: 7.0% vs. 4.8% (P < 0.0001)] compared with patients with a more recent diagnosis. After adjustments, longer HF duration was independently associated with poorer outcome. Effects of ivabradine were independent of HF duration. CONCLUSIONS: Duration of HF predicts outcome independently of risk indicators such as higher age, greater severity and more co-morbidities. Heart rate reduction with ivabradine improved outcomes independently of HF duration. Thus, HF treatments should be initiated early and it is important to characterize HF populations according to the chronicity of HF in future trials.

- AimsIn heart failure, non-adherence increases events; in turn, the effect of hospitalization on adherence is incompletely understood. We explored the relationship of non-adherence to outcomes, hospitalizations with non-adherence, and the influence of non-adherence on treatment effects of heart rate lowering with ivabradine. Methods and resultsIn the randomized, controlled Systolic Heart failure treatment with the If-inhibitor ivabradine Trial (SHIFT), we studied the effect of non-adherence (n = 1287) compared with adherence (n=5204) on cardiovascular outcomes. After adjustment, non-adherence was associated with the primary composite endpoint of cardiovascular death and heart failure hospitalization (hazard ratio 3.47, 95% confidence interval 2.91-4.13, P < 0.0001). No interaction with the treatment groups of placebo or ivabradine (P for interaction 0.54) occurred. Similar results for cardiovascular death and heart failure hospitalization, as well as for cardiovascular hospitalization, heart failure death, and total death were observed. The effect of ivabradine was maintained in patients being adherent or becoming non-adherent during the trial (P for interaction=0.54). Patients with a previous hospitalization were more likely to become non-adherent thereafter. ConclusionsNon-adherence identifies a group at particularly high cardiovascular event risk independent of treatment allocation. Non-adherent patients in the ivabradine group maintain a treatment benefit. Patients with previous hospitalizations are more likely to become non-adherent and represent a group of particularly high-risk patients in whom special attention to stimulate adherence may be valuable.

- AIMS: Analysis of 24-h Holter recordings was a pre-specified substudy of SHIFT (Systolic Heart Failure Treatment with the If Inhibitor Ivabradine Trial) for exploring the heart rhythm safety of ivabradine and to determine effects of ivabradine on 24-h, daytime, and night-time heart rate (HR) compared with resting office HR. METHODS AND RESULTS: The 24-h Holter monitoring was performed at baseline and 8 months after randomization to ivabradine (n = 298) or matching placebo (n = 304) titrated maximally to 7.5 mg b.i.d. in patients with baseline HR >/=70 b.p.m. Patients received guideline-based optimized heart failure therapy including ACE inhibitors and/or ARBs in 93% and beta-blockers at maximally tolerated doses in 93%. After 8 months, HR over 24 h decreased by 9.5 +/- 10.0 b.p.m. with ivabradine, from 75.4 +/- 10.3 b.p.m. (P < 0.0001), and by 1.2 +/- 8.9 b.p.m. with placebo, from 74.8 +/- 9.7 b.p.m. (P < 0.0001 for difference vs. ivabradine). HR reduction with ivabradine was similar in resting office and in 24-h, awake, and asleep recordings, with beneficial effects on HR variability and no meaningful increases in supraventricular or ventricular arrhythmias. At 8 months, 21.3% on ivabradine vs. 8.5% on placebo had >/=1 episode of HR <40 b.p.m. (P < 0.0001). No episode of HR <30 b.p.m. was recorded; 3 (1.2%) patients had RR intervals >2.5 s on ivabradine vs. 4 (1.6%) patients on placebo. No RR intervals >3 s were identified in patients taking ivabradine. CONCLUSION: Ivabradine safely and significantly lowers HR and improves HR variability in patients with systolic heart failure, without inducing significant bradycardia, ventricular arrhythmias, or supraventricular arrhythmias.

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose: To estimate healthcare resource utilization among patients with heart failure (HF) with preserved (HFpEF) versus reduced (HFrEF) ejection fraction using population data from two Swedish counties.Methods: Patients with HF were identified via electronic medical records (EMRs) from primary and/or secondary care in Uppsala and Västerbotten, linked via unique identifiers to data from the National Patient Register and Swedish Prescribed Drug Register. Local echocardiography data were used to identify HFpEF (defined as ejection fraction ≥50%) and HFrEF (defined as <50%). Patients aged ≥18 years with ≥2 diagnoses of HF between 01/01/2010 and 31/03/2015 and an ICD-10 diagnostic code of I50 (inclusive of all granular codes), I42.0, I42.6, I42.7, I42.9, I110, I130 or I132 in any position were included. Patients were followed from date of first diagnosis (index date) to end of study period or EMR collection, date of death or loss to follow-up for other reasons, whichever came first. Unadjusted all-cause and cardiovascular disease (CVD)-related hospitalization rates were assessed using a Cox proportional hazards model, accounting for age, sex, setting of first diagnosis (primary vs secondary care), HF phenotype and NT-proBNP level.Results: In total, 8702 patients with HF were identified. HF phenotype was known in 3167 patients; 64.6% had HFrEF, 35.4% had HFpEF. Patients with HFrEF were younger (mean±SD: 69.9±13.7 vs 74.2±12.6 years) with a lower Charlson comorbidity index (1.65 vs 1.83) than those with HFpEF. All-cause hospitalization rates were marginally lower for HFrEF than for HFpEF (mean [95% CI] proportion of patients hospitalized within 1 year of diagnosis, 72.5 [70.1–74.8]% vs 73.8 [70.7–77.0]%; hazard ratio [HR] over whole follow-up period, 0.87 [0.79–0.97], p=0.0093). The proportion of patients hospitalized was higher for those diagnosed in secondary care than in primary care, particularly within 1 year of diagnosis (1-year rate, 69.6 [68.3–71.0]% vs 59.1 [56.8–61.4]%; HR, 1.15 [1.07–1.23], p=0.0002). Similar trends were observed for CVD-related hospitalization rates for HFrEF vs HFpEF (1-year rate, 69.5 [67.1–71.9]% vs 70.7 [67.5–74.0]%; HR, 0.89 [0.81–0.99], p=0.0309) and for patients diagnosed in secondary vs primary care (1-year rate, 66.6 [65.3–68.0]% vs 56.2 [53.8–58.5]%; HR, 1.15 [1.07–1.24], p=0.0001). Numbers of hospitalizations and outpatient visits decreased with time after diagnosis for HFrEF, but increased slightly for HFpEF after 2 years (Figure). The mean±SD total number of all-cause days of hospitalization during the first year after diagnosis was lower in patients with HFrEF vs HFpEF (19.9±26.1 vs 26.3±34.5 days), while the number of HF-related days of hospitalization was similar (16.0±22.4 vs 17.2±24.0 days).Conclusions: Number and duration of hospital stays were significantly lower over time in patients with HFrEF than HFpEF; this may be explained by the comorbidity burden in the latter group.

- AIMS: Growth differentiation factor-15 (GDF-15) is associated with adverse prognosis in cardiovascular (CV) and non-CV diseases. We evaluated the association of GDF-15 with CV and non-CV outcomes in the PARADIGM-HF trial. METHODS AND RESULTS: In 1935 patients with heart failure and reduced ejection fraction (HFrEF) in PARADIGM-HF, median GDF-15 values were elevated and similar in sacubitril/valsartan and enalapril patients (1626 ng/L and 1690 ng/L, respectively). Diabetes, age, creatinine, high-sensitive troponin T, N-terminal pro-B-type natriuretic peptide, and New York Heart Association class III/IV were most strongly associated with elevated GDF-15 values (all P < 0.001) (adjusted R(2) = 0.3857). Baseline GDF-15 and changes in GDF-15 at both 1 month and 8 months (log-transformed) were associated with subsequent mortality and CV events. Each 20% increment in baseline GDF-15 value was associated with a higher risk of mortality [adjusted hazard ratio (HR) 1.13, 95% confidence interval (CI) 1.08-1.18, P < 0.001], the combined endpoint of CV death or hospitalization for heart failure (adjusted HR 1.09, 95% CI 1.05-1.14, P < 0.001) and heart failure death (adjusted HR 1.16, 95% CI 1.05-1.28, P < 0.001). Changes in GDF-15 were not influenced by assigned therapy (all P-values >/= 0.1). CONCLUSION: In patients with ambulatory HFrEF, GDF-15 is not modified by sacubitril/valsartan and is strongly associated with mortality and CV outcomes, suggesting that GDF-15 is a marker of poor outcomes in these patients. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT01035255.

- AIMS: Symptom severity assessed by NYHA functional class and QRS duration are essential criteria for selection of heart failure (HF) patients for CRT. This study assessed the relationship between NYHA class, QRS duration, and survival in a nationwide HF registry.METHODS AND RESULTS: We studied 13 423 patients with HF in NYHA class II-IV and LVEF <40% in the Swedish Heart Failure Registry. Survival was followed via the Swedish Population Registry. Of 12 534 patients without CRT (age 71 ± 12 years, 29% women), 51% and 49% were in NYHA class II and III-IV, respectively. Patients in NYHA class II compared with class III-IV were younger (69 vs. 73 years), and had a better systolic function (49% vs. 58% with LVEF <30%), P <0.001 for all, and a favourable co-morbidity profile. QRS duration was 116 ± 29 ms in NYHA class II and 119 ± 29 ms in NYHA class III-IV with QRS ≥120 ms found in 37% vs. 44%, and an LBBB in 23% vs. 28% (P < 0.001 for all). Upon multivariable Cox regression adjusting for 40 clinically relevant variables, mortality risk was higher in NYHA class III-IV vs. class II, with a hazard ratio (HR) of 1.31, 95% confidence interval (CI) 1.23-1.40. Mortality was also higher with QRS prolongation ≥120 ms vs. narrow QRS. The HR in NYHA class II patients with non-LBBB was 1.19 (95% CI 1.05 - 1.36) and in those with LBBB it was 1.16 (95% CI 1.03-1.41). The corresponding HRs in NYHA class III-IV were 1.33 (95% CI 1.21-1.47) and 1.12 (95% CI 1.02-1.22). There was no significant interaction between the effects of NYHA class and QRS duration or morphology on mortality. Applying different scenarios to estimate guideline adherence, fewer patients with NYHA class II (range 14.4-42.6%) compared with NYHA class III-IV (18.0-45.4%) had received a CRT device when indicated.CONCLUSIONS: In HF with reduced LVEF, QRS prolongation is common and independently linked to worse survival. The increase in mortality risk associated with QRS prolongation of both LBBB and non-LBBB morphology is similar in NYHA class II and III-IV.

- 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.

- Background and Aim: Left atrial (LA) enlargement is associated with paroxysmal atrial fibrillation (PAF) incidence and outcome. The predictive role of the LA size in AF treatment with catheter ablation is still controversial. The aim of this meta-analysis was to analyze the potential association between LA diameter in patients with PAF undergoing ablation and AF recurrence after ablation.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to December 2016 in order to select clinical trial and observational studies, which assessed the predictive role of LA diameter in AF recurrence after catheter-ablation. 2962 patients from 16 studies with paroxysmal AF (PAF) were included.Results: The pooled analysis showed that after a follow-up period of 19. 66± 8.31 months, patients with AF recurrence had larger LA size compared with those without AF recurrence, with a weighted mean difference (WMD) 2.31 ([95% CI 1.27 to 3.34], P < 0.0001). LA diameter ≥40 mm predicted AF recurrence HR:1.04 [95% CI 1.00 to 1.08], P=0.04), but the best cut-off value, in all included patients, was ≥50mm HR:3.08 [95% CI 1.47 to 6.49], P=0.003).Conclusions: Enlarged left atrium in patients with PAF undergoing catheter ablation predicts recurrences. The diameter more than 50 mm is the best cut-off of the recurrences of AF, but diameter of 40 mm also can predict recurrences in these patients.

- AimsWe examined the relationship between different degrees of QRS prolongation and different QRS morphologies and clinical outcomes in patients with heart failure, reduced ejection fraction (HF-REF), and mild symptoms in the Eplerenone in Mild Patients Hospitalization and SurvIval Study in Heart Failure trial (EMPHASIS-HF). We also evaluated the effect of eplerenone in these patients according to QRS duration/morphology. Methods and resultsPatients were categorized as: QRS duration (ms) (i) <120 (n = 1375); (ii) 120-149 (n = 517); and (iii) 150 (n = 383), and QRS morphology (i) normal (n = 1252); (ii) left bundle branch block (BBB) (n = 608); and (iii) right BBB/intraventricular conduction defect (IVCD) (n = 415). The outcomes examined were the composite of cardiovascular death or heart failure hospitalization and all-cause mortality. Both abnormal QRS duration and QRS morphology were associated with higher risk, e.g. the rates of the composite outcome were: 10.2, 17.6, and 15.5 per 100 patient-years in the <120, 120-149, and 150ms groups, respectively. Eplerenone reduced the risk of the primary outcome and mortality, compared with placebo, consistently across the QRS duration/morphology subgroups. ConclusionWe found that even moderate prolongation of QRS duration and right BBB/IVCD were associated with a high risk of adverse outcomes in HF-REF. Eplerenone was similarly effective, irrespective of QRS duration/morphology.

- AIMS: Inhibition of neprilysin, an enzyme degrading natriuretic and other vasoactive peptides, is beneficial in heart failure with reduced ejection fraction (HFrEF), as shown in PARADIGM-HF which compared the angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril/valsartan with enalapril. As neprilysin is also one of many enzymes clearing amyloid-beta peptides from the brain, there is a theoretical concern about the long-term effects of sacubitril/valsartan on cognition. Therefore, we have examined dementia-related adverse effects (AEs) in PARADIGM-HF and placed these findings in the context of other recently conducted HFrEF trials. METHODS AND RESULTS: In PARADIGM-HF, patients with symptomatic HFrEF were randomized to sacubitril/valsartan 97/103 mg b.i.d. or enalapril 10 mg b.i.d. in a 1:1 ratio. We systematically searched AE reports, coded using the Medical Dictionary for Regulatory Activities (MedDRA), using Standardized MedDRA Queries (SMQs) with 'broad' and 'narrow' preferred terms related to dementia. In PARADIGM-HF, 8399 patients aged 18-96 years were randomized and followed for a median of 2.25 years (up to 4.3 years). The narrow SMQ search identified 27 dementia-related AEs: 15 (0.36%) on enalapril and 12 (0.29%) on sacubitril/valsartan [hazard ratio (HR) 0.73, 95% confidence interval (CI) 0.33-1.59]. The broad search identified 97 (2.30%) and 104 (2.48%) AEs (HR 1.01, 95% CI 0.75-1.37), respectively. The rates of dementia-related AEs in both treatment groups in PARADIGM-HF were similar to those in three other recent trials in HFrEF. CONCLUSION: We found no evidence that sacubitril/valsartan, compared with enalapril, increased dementia-related AEs, although longer follow-up may be necessary to detect such a signal and more sensitive tools are needed to detect lesser degrees of cognitive impairment. Further studies to address this question are warranted.

- Myriad advances in all fields of cardiac imaging have stimulated and reflected new understanding of cardiac performance, myocardial damage and the mechanisms of heart failure. In this paper, the Heart Failure Association assesses the potential usefulness of innovative imaging modalities in enabling more precise diagnostic and prognostic evaluation, as well as in guiding treatment strategies. Many new methods have gradually penetrated clinical practice and are on their way to becoming a part of routine evaluation. This paper focuses on myocardial deformation and three- dimensional ultrasound imaging; stress tests for the evaluation of contractile and filling function; the progress of magnetic resonance techniques; molecular imaging and other sound innovations. The Heart Failure Association aims to highlight the ways in which paradigms have shifted in several areas of cardiac assessment. These include reassessing of the simplified concept of ejection fraction and implementation of the new parameters of cardiac performance applicable to all heart failure phenotypes; switching from two-dimensional to more accurate and reproducible three-dimensional ultrasound volumetric evaluation; greater tissue characterization via recently developed magnetic resonance modalities; moving from assessing cardiac function and congestion at rest to assessing it during stress; from invasive to novel non-invasive hybrid techniques depicting coronary anatomy and myocardial perfusion; as well as from morphometry to the imaging of pathophysiologic processes such as inflammation and apoptosis. This position paper examines the specific benefits of imaging innovations for practitioners dealing with heart failure aetiology, risk stratification and monitoring, and, in addition, for scientists involved in the development of future research.

- AimsHeart failure (HF) and dementia frequently coexist, but little is known about their types, relationships to each other and prognosis. The aims were to (i) describe patients with HF and dementia, assess (ii) the proportion of specific dementia disorders in types of HF based on ejection fraction and (iii) the prognostic role of types of HF and dementia disorders. Methods and resultsThe Swedish Heart Failure Registry (RiksSvikt) and The Swedish Dementia Registry (SveDem) were record-linked. Associations between dementia disorders and HF types were assessed with multinomial logistic regression and survival was investigated with Kaplan-Meier analysis and multivariable Cox regression. We studied 775 patients found in both registries (55% men, mean age 82years). Ejection fraction was preserved in 38% of patients, reduced in 34%, and missing in 28%. The proportions of dementia disorders were similar across HF types. Vascular dementia was the most common dementia disorder (36%), followed by other dementias (28%), mixed dementia (20%), and Alzheimer disease (16%). Over a mean follow-up of 1.5years, 76% of patients survived 1year. We observed no significant differences in survival with regard to HF type (P=0.2) or dementia disorder (P=0.5). After adjustment for baseline covariates, neither HF types nor dementia disorders were independently associated with survival. ConclusionsHeart failure with preserved ejection fraction was the most common HF type and vascular dementia was the most common dementia disorder. The proportions of dementia disorders were similar across HF types. Neither HF types nor specific dementia disorders were associated with survival.

- AIMS: It is not known whether concomitant use of aspirin might attenuate the beneficial effects of mineralocorticoid receptor antagonists (MRAs). The purpose of this subgroup analysis was to explore the interaction between baseline aspirin treatment and the effect of eplerenone on the primary efficacy outcomes (composite of hospitalization for heart failure or cardiovascular mortality), its components, and safety markers [estimated glomerular filtration rate (eGFR), systolic blood pressure (SBP), and serum potassium >5.5 mmol/L] in the Eplerenone in Mild Patients Hospitalization and SurvIval Study in Heart Failure trial (EMPHASIS-HF). METHODS AND RESULTS: Patients with chronic heart failure, reduced ejection fraction (HFREF), and mild symptoms were enrolled in EMPHASIS-HF. We evaluated baseline characteristics according to aspirin use. We explored the interaction between aspirin and eplerenone, using Cox proportional hazards models providing adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) and P-values for interaction. Of the 2737 patients randomized, 1605 patients (58.6%) were taking aspirin. The beneficial effects of eplerenone on the primary endpoint were similar in patients not treated (adjusted HR 0.59, 95% CI 0.46-0.75) or treated (adjusted HR 0.71, 95% CI 0.59-0.87) with aspirin at baseline (interaction P-value = 0.19). We did not observe any significant modification of the safety markers by aspirin that was clinically meaningful. CONCLUSION: Aspirin use in patients with chronic systolic heart failure and mild symptoms did not substantially reduce the overall beneficial effects of the MRA eplerenone contrary to what has been described in some studies with ACE inhibitors.

- Aims Up to one-third of patients with diabetes mellitus and heart failure (HF) are treated with insulin. As insulin causes sodium retention and hypoglycaemia, its use might be associated with worse outcomes. Methods and results We examined two datasets: 24 012 patients with HF from four large randomized trials and an administrative database of 4 million individuals, 103 857 of whom with HF. In the former, survival was examined using Cox proportional hazards models adjusted for baseline variables and separately for propensity scores. Fine-Gray competing risk regression models were used to assess the risk of hospitalization for HF. For the latter, a case-control nested within a population-based cohort study was conducted with propensity score. Prevalence of diabetes mellitus at study entry ranged from 25.5% to 29.5% across trials. Insulin alone or in combination with oral hypoglycaemic drugs was prescribed at randomization to 24.4% to 34.5% of the patients with diabetes. The rates of death from any cause and hospitalization for HF were higher in patients with vs. without diabetes, and highest of all in patients prescribed insulin [propensity score pooled hazard ratio for all-cause mortality 1.27 (1.16-1.38), for HF hospitalization 1.23 (1.13-1.33)]. In the administrative registry, insulin prescription was associated with a higher risk of all-cause death [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.87-2.19] and rehospitalization for HF (OR 1.42, 95% CI 1.32-1.53). Conclusions Whether insulin use is associated with poor outcomes in HF should be investigated further with controlled trials, as should the possibility that there may be safer alternative glucose-lowering treatments for patients with HF and type 2 diabetes mellitus.

- Despite the availability of a number of different classes of therapeutic agents with proven efficacy in heart failure, the clinical course of heart failure patients is characterized by a reduction in life expectancy, a progressive decline in health-related quality of life and functional status, as well as a high risk of hospitalization. New approaches are needed to address the unmet medical needs of this patient population. The European Medicines Agency (EMA) is undertaking a revision of its Guideline on Clinical Investigation of Medicinal Products for the Treatment of Chronic Heart Failure. The draft version of the Guideline was released for public consultation in January 2016. The Cardiovascular Round Table of the European Society of Cardiology (ESC), in partnership with the Heart Failure Association of the ESC, convened a dedicated two-day workshop to discuss three main topic areas of major interest in the field and addressed in this draft EMA guideline: (i) assessment of efficacy (i.e. endpoint selection and statistical analysis); (ii) clinical trial design (i.e. issues pertaining to patient population, optimal medical therapy, run-in period); and (iii) research approaches for testing novel therapeutic principles (i.e. cell therapy). This paper summarizes the key outputs from the workshop, reviews areas of expert consensus, and identifies gaps that require further research or discussion. Collaboration between regulators, industry, clinical trialists, cardiologists, health technology assessment bodies, payers, and patient organizations is critical to address the ongoing challenge of heart failure and to ensure the development and market access of new therapeutics in a scientifically robust, practical and safe way.

- AimsThe European Society of Cardiology Heart Failure Long-Term Registry (ESC-HF-LT-R) was set up with the aim of describing the clinical epidemiology and the 1-year outcomes of patients with heart failure (HF) with the added intention of comparing differences between participating countries. Methods and resultsThe ESC-HF-LT-R is a prospective, observational registry contributed to by 211 cardiology centres in 21 European and/or Mediterranean countries, all being member countries of the ESC. Between May 2011 and April 2013 it collected data on 12440 patients, 40.5% of them hospitalized with acute HF (AHF) and 59.5% outpatients with chronic HF (CHF). The all-cause 1-year mortality rate was 23.6% for AHF and 6.4% for CHF. The combined endpoint of mortality or HF hospitalization within 1year had a rate of 36% for AHF and 14.5% for CHF. All-cause mortality rates in the different regions ranged from 21.6% to 36.5% in patients with AHF, and from 6.9% to 15.6% in those with CHF. These differences in mortality between regions are thought reflect differences in the characteristics and/or management of these patients. ConclusionThe ESC-HF-LT-R shows that 1-year all-cause mortality of patients with AHF is still high while the mortality of CHF is lower. This registry provides the opportunity to evaluate the management and outcomes of patients with HF and identify areas for improvement.

- AimWe aimed to study the relationships of loop diuretic dose with renal function and clinical outcomes in patients with chronic heart failure (HF). Methods and resultsLoop diuretic dose at baseline was recorded in patients included in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA). The relationship to change in estimated glomerular filtration rate (eGFR) over time and to the first occurrence of the composite outcome of cardiovascular (CV) death or hospitalization owing to HF was examined in propensity score matched cohorts. Of the 5011 patients, 2550, 745, and 449 were receiving >80mg (high), 41-80mg (medium) and 40mg (low) of loop diuretics in furosemide equivalent daily dosages, respectively, which were used to assemble 229, 385, and 1045 pairs of propensity-matched high, medium, and low dose cohorts. Compared with matched no loop diuretic groups, eGFR declined 0.30.2, 0.3 +/- 0.3 and 1.2 +/- 0.5mL/min/1.73m(2)/year in the low-, medium-, and high-dose groups, respectively. Compared with matched no loop diuretic groups, hazard ratios (HR) (95% confidence intervals) for outcome associated with low-, medium- and high-dose groups were 1.71 (1.41-2.06), 1.99 (1.50-2.64), and 2.94 (1.95-4.41), respectively. Higher loop diuretic dose was particularly associated with increased risk for hospitalization owing to HF: HR 4.80 (2.75-8.37), P<0.001. ConclusionsThe use of loop diuretics was associated with a slightly greater rate of decline in eGFR, which did not vary significantly by diuretic dose.Loop diuretic dose was associated with higher risks of (CV) mortality and predominantly hospitalization owing to HF, which appeared to be higher among those receiving higher daily doses.

- AIMS: We investigated the association between worsening renal function (WRF) that occurs during renin-angiotensin-aldosterone system inhibition initation and outcome in heart failure (HF) patients with preserved ejection fraction (HFPEF) and compared this with HF patients with reduced ejection fraction (HFREF). METHODS AND RESULTS: We examined changes in estimated glomerular filtration rate (GFR) and the relationship between WRF (defined as >/=26.5 micromol/L and >/=25% increase in serum creatinine from baseline to 6 weeks) and outcome, according to randomized treatment, in patients with HFREF (EF <45%; n = 1569) and HFPEF (EF >/=45%; n = 836) in the CHARM programme. The primary outcome was cardiovascular death or HF hospitalization. Estimated GFR decreased 9.0 +/- 21 vs. 4.0 +/- 21 mL/min/1.73 m2 with candesartan and placebo, respectively, and this was similar in HFREF and HFPEF. WRF developed more frequently with candesartan, 16% vs. 7%, P < 0.001, with similar findings in patients with HFREF and HFPEF. WRF was associated with a higher risk of the primary outcome: multivariable hazard ratio (HR) 1.26, 95% confidence interval 1.03-1.54, P = 0.022, in both treatment groups, and in both HFREF and HFPEF (P for interaction 0.98). In HFREF, WRF was mostly related to HF hospitalization, while in HFPEF, WRF seemed more associated with mortality. CONCLUSIONS: GFR decreased more and WRF was more common with candesartan compared with placebo, and this was similar in HFREF and HFPEF. WRF was associated with worse outcomes in HFREF and HFPEF. Although no formal interaction was present, the association between candesartan treatment, WRF, and type of clinical outcome was slightly different between HFREF and HFPEF.

- Nearly 60% of the world's population lives in Asia but little is known about the characteristics and outcomes of Asian patients with heart failure with reduced ejection fraction (HFrEF) compared to other areas of the world.We pooled two, large, global trials, with similar design, in 13174 patients with HFrEF (patient distribution: China 833, India 1390, Japan 209, Korea 223, Philippines 223, Taiwan 199 and Thailand 95, Western Europe 3521, Eastern Europe 4758, North America 613, and Latin America 1110). Asian patients were younger (55.0-63.9years) than in Western Europe (67.9years) and North America (66.6years). Diuretics and devices were used less, and digoxin used more, in Asia. Mineralocorticoid receptor antagonist use was higher in China (66.3%), the Philippines (64.1%) and Latin America (62.8%) compared to Europe and North America (range 32.8% to 49.6%). The rate of cardiovascular death/heart failure hospitalization was higher in Asia (e.g. Taiwan 17.2, China 14.9 per 100patient-years) than in Western Europe (10.4) and North America (12.8). However, the adjusted risk of cardiovascular death was higher in many Asian countries than in Western Europe (except Japan) and the risk of heart failure hospitalization was lower in India and in the Philippines than in Western Europe, but significantly higher in China, Japan, and Taiwan.Patient characteristics and outcomes vary between Asia and other regions and between Asian countries. These variations may reflect several factors, including geography, climate and environment, diet and lifestyle, health care systems, genetics and socioeconomic influences.

- Background Cardiac resynchronisation therapy (CRT) reduces morbidity and mortality in appropriately selected patients with heart failure and is strongly recommended for such patients by guidelines. A European Society of Cardiology (ESC) CRT survey conducted in 2008-2009 showed considerable variation in guideline adherence and large individual, national and regional differences in patient selection, implantation practice and follow-up. Accordingly, two ESC associations, the European Heart Rhythm Association and the Heart Failure Association, designed a second prospective survey to describe contemporary clinical practice regarding CRT. Methods and results A survey of the clinical practice of CRT-P and CRT-D implantation was conducted from October 2015 to December 2016 in 42 ESC member countries. Implanting centres provided information about their hospital and CRT service and were asked to complete a web-based case report form collecting information on patient characteristics, investigations, implantation procedures and complications during the index hospitalisation. The 11 088 patients enrolled represented 11% of the total number of expected implantations in participating countries during the survey period; 32% of patients were aged >= 75 years, 28% of procedures were upgrades from a permanent pacemaker or implantable cardioverter-defibrillator and 30% were CRT-P rather than CRT-D. Most patients (88%) had a QRS duration >= 130 ms, 73% had left bundle branch block and 26% were in atrial fibrillation at the time of implantation. Large geographical variations in clinical practice were observed.
