- Background The pathophysiology of heart failure with preserved ejection fraction is poorly understood, but may involve a systemic proinflammatory state. Therefore, statins might improve outcomes in patients with heart failure with preserved ejection fraction defined as 50%. Methods and Results Of 46 959 unique patients in the prospective Swedish Heart Failure Registry, 9140 patients had heart failure and ejection fraction 50% (age 7711 years, 54.0% women), and of these, 3427 (37.5%) were treated with statins. Propensity scores for statin treatment were derived from 40 baseline variables. The association between statin use and primary (all-cause mortality) and secondary (separately, cardiovascular mortality, and combined all-cause mortality or cardiovascular hospitalization) end points was assessed with Cox regressions in a population matched 1:1 based on age and propensity score. In the matched population, 1-year survival was 85.1% for statin-treated versus 80.9% for untreated patients (hazard ratio, 0.80; 95% confidence interval, 0.72-0.89; Pless than0.001). Statins were also associated with reduced cardiovascular death (hazard ratio, 0.86; 95% confidence interval, 0.75-0.98; P=0.026) and composite all-cause mortality or cardiovascular hospitalization (hazard ratio, 0.89; 95% confidence interval, 0.82-0.96; P=0.003). Conclusions In heart failure with ejection fraction 50%, the use of statins was associated with improved outcomes. The mechanisms should be evaluated and the effects tested in a randomized trial.

- Background-In heart failure (HF) with reduced ejection fraction, randomized trials of statins did not demonstrate improved outcomes. However, randomized trials may not always be generalizable. The aim was to determine whether statins are associated with improved outcomes in an unselected nationwide population of patients with HF with reduced ejection fraction overall and in relation to ischemic heart disease (IHD). Methods and Results-In the Swedish Heart Failure Registry, 21 864 patients with HF with reduced ejection fraction (age +/- SD, 72+/-12 years; 29% women), of whom 10 345 (47%) were treated with statins, were studied. Propensity scores for statin use were derived from 42 baseline variables. The associations between statin use and outcomes were assessed with Cox regressions in a population matched 1: 1 based on propensity score and age and in the overall population with adjustment for propensity score and age. The primary outcome was all-cause mortality; secondary outcomes were cardiovascular mortality; HF hospitalization; and combined all-cause mortality or cardiovascular hospitalization. Survival at 1 year in the matched population was 83% for statin-treated versus 79% for untreated patients (hazard ratio, 0.81; 95% confidence interval, 0.76-0.86; Pless than0.001). In the unmatched population, 1-year survival was 85% for statin-treated versus 79% for untreated patients, hazard ratio after adjustment for propensity score and age was 0.84 (95% confidence interval, 0.80-0.89; Pless than0.001). No examined baseline variables interacted with statin use except for IHD (P=0.001), with a hazard ratio of 0.76 (95% confidence interval, 0.70-0.82, Pless than0.001) with IHD and 0.95 (95% confidence interval, 0.85-1.07; P=0.430 without IHD. Statin use was also associated with reduced risk for all 3 secondary outcomes. Conclusions-In an unselected nationwide population of patients with HF with reduced ejection fraction, statins were associated with improved outcomes, specifically in the presence of IHD. This contrasts with previous randomized controlled trials. Additional randomized controlled trials with more generalized inclusion or focused on IHD may be warranted.

- OBJECTIVES The study sought to compare the prevalence, clinical correlates and prognostic impact of diabetes in Southeast Asian versus white patients with heart failure (HF) with preserved or reduced ejection fraction. BACKGROUND Diabetes mellitus is common in HF and is associated with impaired prognosis. Asia is home to the majority of the worlds diabetic population, yet data on the prevalence and clinical significance of diabetes in Asian patients with HF are sparse, and no studies have directly compared Asian and white patients. METHODS Two contemporary population-based HF cohorts were combined: from Singapore (n 1,002, median [25th to 75th percentile] age 62 [54 to 70] years, 76% men, 19.5% obesity) and Sweden (n =19,537, 77 [68 to 84] years, 60% men, 24.8% obesity). The modifying effect of ethnicity on the relationship between diabetes and clinical correlates or prognosis (HF hospitalization and all-cause mortality) was examined using interaction terms. RESULTS Diabetes was present in 569 (57%) Asian patients versus 4,680 (24%) white patients (p amp;lt; 0.001). Adjusting for clinical covariates, obesity was more strongly associated with diabetes in white patients (odds ratio [OR]: 3.45;. 95% confidence interval [CI]: 2.86 to 4.17) than in Asian patients (OR: 1.82; 95% CI: 1.13 to 2.96; P-interaction = 0.026). Diabetes was more strongly associated with increased HF hospitalization and all-cause mortality in Asian patients (hazard ratio: 1.50; 95% CI: 1.21 to 1.87) than in white patients (hazard ratio: 1.29; 95% CI: 1.22 to 1.36; P-interaction = 0.045). CONCLUSIONS Diabetes was 3-fold more common in Southeast Asian compared to white patients with HF, despite younger age and less obesity, and more strongly associated with poor outcomes in Asian patients than white patients. These results underscore the importance of ethnicity-tailored aggressive strategies to prevent diabetes and its complications. (C) 2017 by the American College of Cardiology Foundation.

- AIMS: To evaluate the quality of heart failure (HF) care using the European Society of Cardiology (ESC) quality indicators (QIs) for HF and to assess whether better quality of care is associated with improved outcomes.METHODS AND RESULTS: We performed a nationwide cohort study using the Swedish HF registry, consisting of patients with any type of HF at their first outpatient visit or hospitalization. Independent participant data for quality of HF care was evaluated against the ESC QIs for HF, and association with mortality estimated using multivariable Cox regression. In total, 43 704 patients from 80 hospitals across Sweden enrolled between 2013-2019 were included, with median follow-up 23.6 months. Of the 16 QIs for HF, 13 could be measured and 5 were inversely associated with all-cause mortality during follow-up. Higher attainment (≥50% vs. <50% attainment) of the composite opportunity-based score (combination of QIs into a single score) for patients with reduced ejection fraction was associated with lower all-cause mortality (adjusted hazard ratio 0.81; 95% confidence interval 0.72-0.91). Attainment of the composite score was less in the outpatient than inpatient setting (adjusted odds ratio 0.85; 95% confidence interval 0.72-0.99). Quality of care varied across hospitals, with assessment of health-related quality of life being the indicator with the widest variation in attainment (interquartile range 61.7%).CONCLUSION: Quality of HF care may be measured using the ESC HF QIs. In Sweden, attainment of HF care evaluated using the QIs demonstrated between and within hospital variation, and many QIs were inversely associated with mortality.

- Aims The SOLOIST-WHF trial demonstrated efficacy of sotagliflozin in patients with type 2 diabetes mellitus (T2DM) and recent worsening heart failure (HF) regardless of ejection fraction (EF). Selection criteria in trials may limit their generalizability. Therefore, we aimed to investigate eligibility for sotagliflozin based on the SOLOIST-WHF criteria in a real-world HF population. Methods and results SOLOIST-WHF criteria were applied to patients stabilized after HF hospitalization in the Swedish HF Registry according to (i) literal scenario (all inclusion/exclusion criteria) or (ii) pragmatic scenario (only criteria likely to influence treatment decisions). Of 5453 inpatients with T2DM and recent worsening HF, 51.4% had reduced EF (HFrEF), 19.1% mildly reduced (HFmrEF), and 29.5% preserved EF (HFpEF). Eligibility (literal) was: 27.2% (32.4% in HFrEF, 24.7% in HFmrEF, 19.7% in HFpEF) and eligibility (pragmatic) was 62.8% (69.1%, 60.3%, 53.4%, respectively). In the literal scenario, criteria limiting eligibility were HF duration <3 months, eGFR <30 ml/min/1.73 m(2), age >85 years, acute coronary syndrome <3 months, and insufficiently high N-terminal pro-B-type natriuretic peptide levels. Eligible vs. non-eligible patients had more severe HF, higher cardiovascular (CV) comorbidity burden, higher use of HF treatments, and higher event rates (all-cause death 30.8 vs. 27.2 per 100 patient-years, CV death 19.1 vs. 16.6, and HF hospitalization 36.7 vs. 24.0). Conclusion In this large, real-world HF cohort with T2DM, similar to 1/3 of patients were eligible for sotagliflozin in the literal and similar to 2/3 of patients in the pragmatic scenario. Eligible patients had more severe HF and higher event rates, in particular CV and HF events.

- Aims Iron deficiency (ID) is associated with poor prognosis regardless of anaemia. Intravenous iron improves quality of life and outcomes in patients with ID and heart failure (HF) with reduced ejection fraction (HFrEF). In the Swedish HF registry, we assessed (i) frequency and predictors of ID testing; (ii) prevalence and outcomes of ID with/without anaemia; (iii) use of ferric carboxymaltose (FCM) and its predictors in patients with ID. Methods and results We used multivariable logistic regressions to assess patient characteristics independently associated with ID testing/FCM use, and Cox regressions to assess risk of outcomes associated with ID. Of 21 496 patients with HF and any ejection fraction enrolled in 2017-2018, ID testing was performed in 27%. Of these, 49% had ID and more specifically 36% had ID-/anaemia-, 15% ID-/anaemia+, 29% ID+/anaemia-, and 20% ID+/anaemia+ (48%, 39%, 13%, 30% and 18% in HFrEF, respectively). Risk of recurrent all-cause hospitalizations was higher in patients with ID regardless of anaemia. Of 1959 patients with ID, 19% received FCM (24% in HFrEF). Important independent predictors of ID testing and FCM use were anaemia, higher New York Heart Association class, having HFrEF, and referral to HF specialty care. Conclusion In this nationwide HF registry, ID testing occurred in only about a quarter of the patients. Among tested patients, ID was present in one half, but only one in five patients received FCM indicating low adherence to current guidelines on screening and treatment.

- Aims Use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in real-world heart failure (HF) is poorly characterised. In contemporary patients with HF and type 2 diabetes mellitus (T2DM) we assessed over time SGLT2i use, clinical characteristics and outcomes associated with SGLT2i use. Methods and results Type 2 diabetes patients enrolled in the Swedish HF Registry between 2016-2018 were considered. We performed multivariable logistic regression models to assess the independent predictors of SGLT2i use and Cox regression models in a 1:3 propensity score-matched cohort and relevant subgroups to investigate the association between SGLT2i use and outcomes. Of 6805 eligible HF patients with T2DM, 376 (5.5%) received SGLT2i, whose use increased over time with 12% of patients on treatment at the end of 2018. Independent predictors of SGLT2i use were younger age, HF specialty care, ischaemic heart disease, preserved kidney function, and absence of anaemia. Over a median follow-up of 256 days, SGLT2i use was associated with a 30% lower risk of cardiovascular (CV) death/first HF hospitalisation (hazard ratio 0.70, 95% confidence interval 0.52-0.95), which was consistent regardless of ejection fraction, background metformin treatment and kidney function. SGLT2i use was also associated with a lower risk of all-cause and CV death, HF and CV hospitalisation, and CV death/myocardial infarction/stroke. Conclusion In a contemporary HF cohort with T2DM, SGLT2i use increased over time, was more common with specialist care, younger age, ischaemic heart disease, and preserved renal function, and was associated with lower mortality and morbidity.

- 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 To investigate the use of guideline-directed medical therapies (GDMT) and associated outcomes in obese (body mass index >= 30 kg/m(2)) versus non-obese patients with heart failure (HF) with reduced ejection fraction (HFrEF). Methods and results Patients with HFrEF from the Swedish HF Registry were included. Of 16 116 patients, 24% were obese. In obese versus non-obese patients, use of treatments was 91% versus 86% for renin-angiotensin system inhibitors (RASi)/angiotensin receptor-neprilysin inhibitors (ARNi), 94% versus 91% for beta-blockers, 53% versus 43% for mineralocorticoid receptor antagonists. Obesity was shown to be independently associated with more likely use of each treatment, triple combination therapy, and the achievement of target dose by multivariable logistic regressions. Multivariable Cox regressions showed use of RASi/ARNi and beta-blockers being independently associated with lower risk of all-cause/cardiovascular death regardless of obesity, although, when considering competing risks, a lower risk of cardiovascular death with RASi/ARNi in obese versus non-obese patients was observed. RASi/ARNi were associated with lower risk of HF hospitalization in obese but not in non-obese patients, whereas beta-blockers were not associated with the risk of HF hospitalization regardless of obesity. At the competing risk analysis, RASi/ARNi use was associated with higher risk of HF hospitalization regardless of obesity. Conclusion Obese patients were more likely to receive optimal treatments after adjustment for factors affecting tolerability, suggesting that perceived beyond actual tolerance issues limit GDMT implementation. RASi/ARNi and beta-blockers were associated with lower mortality regardless of obesity, with a greater association between RASi/ARNi and lower cardiovascular death in obese versus non-obese patients when considering competing risk.

- Aims Hyperkalaemia and hypokalaemia are common in heart failure and associated with worse outcomes. However, the optimal potassium range is unknown. We sought to determine the optimal range of potassium in patients with heart failure and reduced ejection fraction (amp;lt; 40%) by exploring the relationship between baseline potassium level and short- and long-term outcomes using the Swedish Heart Failure Registry from 1 January 2006 to 31 December 2012. Methods and results We assessed the association between baseline potassium level and all-cause mortality at 30 days, 12 months, and maximal follow-up, in uni- and multivariable stratified and restricted cubic spline Cox regressions. Of 13 015 patients, 93.3% had potassium 3.5-5.0 mmol/L, 3.7% had potassium amp;lt;3.5 mmol/L, and 3.0% had potassium amp;gt;5.0 mmol/L. Potassium 5.0 mmol/L were more common with lower estimated glomerular filtration rate and heart failure of longer duration and greater severity. The potassium level associated with the lowest hazard risk for mortality at 30 days, 12 months, and maximal follow-up was 4.2 mmol/L, and there was a steep increase in risk with both higher and lower potassium levels. In adjusted strata analyses, lower potassium was independently associated with all-cause mortality at 12 months and maximal follow-up, while higher potassium levels only increased risk at 30 days. Conclusion In this nationwide registry, the relationship between potassium and mortality was U-shaped, with an optimal potassium value of 4.2 mmol/L. After multivariable adjustment, hypokalaemia was associated with increased long-term mortality but hyperkalaemia was associated with increased short-term mortality.
