- Aims Guidelines recommend target doses (TD) of heart failure (HF) with reduced ejection fraction (HFrEF) medications regardless of sex. Differences in pharmacokinetics and pharmacodynamics may explain heterogeneity in treatment response, adverse reactions, and tolerability issues across sexes. The aim of this study was to explore sex-based differences in the association between TD achievement and mortality/morbidity in HFrEF. Methods and results Patients with HFrEF and HF duration >= 6 months registered in the Swedish HF Registry between May 2000 and December 2020 (follow-up until December 2021) were analysed. Treatments of interest were renin-angiotensin system inhibitors (RASI) or angiotensin receptor-neprilysin inhibitors (ARNI), and beta-blockers. Multivariable Cox regression models were performed to explore the risk of cardiovascular mortality or hospitalization for HF across dose categories in females versus males. A total of 17 912 patients were analysed (median age 77.0 years, interquartile range [IQR] 70.0-83.0), 29% were female. Over a median follow-up of 1.33 years (IQR 0.29-3.22), for RASI/ARNI there was no significant difference in outcome for females achieving 50-99% versus 100% of TD (hazard ratio 0.92, 95% confidence interval 0.83-1.03), whereas males showed a gradual lowering in risk together with the achievement of higher % of TD (p-interaction = 0.030). For beta-blockers the achievement of TD was associated with the lowest risk of outcome regardless of sex. Conclusions Our findings suggest that females and males might differently benefit from the same dose of RASI/ARNI, and do represent a general call for randomized controlled trials to consider sex-specific up-titration schemes when testing HFrEF treatments in need of up-titration.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Heart failure (HF) is a heterogeneous syndrome, and the specific sub-category HF with mildly reduced ejection fraction (EF) range (HFmrEF; 41-49% EF) is only recently recognised as a distinct entity. Cluster analysis can characterise heterogeneous patient populations and could serve as a stratification tool in clinical trials and for prognostication. The aim of this study was to identify clusters in HFmrEF and compare cluster prognosis.Methods and results: Latent class analysis to cluster HFmrEF patients based on their characteristics was performed in the Swedish HF registry (n = 7316). Identified clusters were validated in a Dutch cross-sectional HF registrybased dataset CHECK-HF (n =1536). In Sweden, mortality and hospitalisation across the clusters were compared using a Cox proportional hazard model, with a Fine-Gray sub-distribution for competing risks and adjustment for age and sex. Six clusters were discovered with the following prevalence and hazard ratio with 95% confidence intervals (HR [95%CI]) vs. cluster 1: 1) low-comorbidity (17%, reference), 2) ischaemic-male (13%, HR 0.9 [95% CI 0.7-1.1]), 3) atrial fibrillation (20%, HR 1.5 [95% CI 1.2-1.9]), 4) device/wide QRS (9%, HR 2.7 [95% CI 2.2-3.4]), 5) metabolic (19%, HR 3.1 [95% CI 2.5-3.7]) and 6) cardio-renal phenotype (22%, HR 2.8 [95% CI 2.2-3.6]). The cluster model was robust between both datasets.Conclusion: We found robust clusters with potential clinical meaning and differences in mortality and hospitalisation. Our clustering model could be valuable as a clinical differentiation support and prognostic tool in clinical trial design.

- OBJECTIVES: This study sought to evaluate the incidence, the predictors, and the associations with outcomes of changes in ejection fraction (EF) in heart failure (HF) patients.BACKGROUND: EF determines therapy in HF, but information is scarce about incidence, determinants, and prognostic implications of EF change over time.METHODS: Patients with >= 2 EF measurements were made in the Swedish Heart Failure Registry were categorized as heart failure with preserved ejection fraction (HFpEF) (EF >= 50%), heart failure with midrange ejection fraction (HFmrEF) (EF 40% to 49%), or heart failure with reduced ejection fraction (HFrEF) (EF <40%). Changes among categories were recorded, and associations among EF changes, predictors, and all-cause mortality and/or HF hospitalizations were analyzed using logistic and Cox regressions.RESULTS: Of 4,942 patients at baseline, 18% had HFpEF, 19% had HFmrEF, and 63% had HFrEF. During follow-up, 21% and 18% of HFpEF patients transitioned to HFmrEF and HFrEF, respectively; 37% and 25% of HFmrEF patients transitioned to HFrEF and HFpEF, respectively; and 16% and 10% of HFrEF patients transitioned to HFmrEF and HFpEF, respectively. Predictors of increased EF included use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, female sex, cases of less severe HF, and comorbidities. Predictors of decreased EF included diabetes, ischemic heart disease, and cases of more severe HF. Increased EF was associated with a lower risk (hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.55 to 0.69) and decreased EF with a higher risk (HR: 1.15; 95% CI: 1.01 to 1.30) of mortality and/or HF hospitalizations. Prognostic implications were most evident for transitions to and from HFrEF.CONCLUSIONS: Increases in EF occurred in one-fourth of HFrEF and HFmrEF patients, and decreases occurred in more than one-third of patients with HFpEF and HFmrEF. EF change was associated with a wide range of important clinical, treatment, and organizational factors as well as with outcomes, particularly transitions to and from HFrEF.

- Background: Most randomized trials on implantable cardioverter-defibrillator (ICD) use for primary prevention of sudden cardiac death in heart failure with reduced ejection fraction enrolled patients amp;gt;20 years ago. We investigated the association between ICD use and all-cause mortality in a contemporary heart failure with reduced ejection fraction cohort and examined relevant subgroups. Methods: Patients from the Swedish Heart Failure Registry fulfilling the European Society of Cardiology criteria for primary-prevention ICD were included. The association between ICD use and 1-year and 5-year all-cause and cardiovascular (CV) mortality was assessed by Cox regression models in a 1:1 propensity score-matched cohort and in prespecified subgroups. Results: Of 16 702 eligible patients, only 1599 (10%) had an ICD. After matching, 1305 ICD recipients were compared with 1305 nonrecipients. ICD use was associated with a reduction in all-cause mortality risk within 1 year (hazard ratio, 0.73 [95% CI, 0.60-0.90]) and 5 years (hazard ratio, 0.88 [95% CI, 0.78-0.99]). Results were consistent in all subgroups including patients with versus without ischemic heart disease, men versus women, those aged amp;lt;75 versus amp;gt;= 75 years, those with earlier versus later enrollment in the Swedish heart failure registry, and patients with versus without cardiac resynchronization therapy. Conclusions: In a contemporary heart failure with reduced ejection fraction population, ICD for primary prevention was underused, although it was associated with reduced short- and long-term all-cause mortality. This association was consistent across all the investigated subgroups. These results call for better implementation of ICD therapy.

- Aims Randomized data on the efficacy/safety of cardiac resynchronization therapy with vs. without defibrillator (CRT-D,-P) in heart failure with reduced ejection fraction (HFrEF) are scarce. We aimed to evaluate survival associated with use of CRT-D vs. CRT-P in a contemporary cohort with HFrEF. Methods and results Patients from Swedish HF Registry treated with CRT-D/CRT-P and fulfilling criteria for primary prevention defibrillator use were included. Logistic regression was used to evaluate predictors of CRT-D non-use. All-cause mortality was compared in CRT-D vs. CRT-P by Cox regression in a 1 : 1 propensity-score-matched cohort. Of 1988 patients with CRT, 1108 (56%) had CRT-D and 880 (44%) CRT-P. Older age, higher ejection fraction (EF), female sex, and the lack of referral to HF nurse-led outpatient clinic were major determinants of CRT-D non-use. After matching, 645 CRT-D patients were compared with 645 with CRT-P. The CRT-D use was associated with lower 1- and 3-year all-cause mortality [hazard ratio (HR):0.76, 95% confidence interval (CI):0.58-0.98; HR: 0.82, 95% CI: 0.68-0.99, respectively]. Results were consistent in all pre-specified subgroups except for CRT-D use being associated with lower 3-year mortality in patients with an EF < 30% but not in those with an EF >= 30% (HR: 0.73, 95% CI: 0.59-0.89 and HR: 1.24, 95% CI: 0.83-1.85, respectively; P-interaction = 0.02). Conclusion In a contemporary HFrEF cohort, CRT-D was associated with lower mortality compared with CRT-P. The CRT-D use was less likely in older patients, females, and in patients not referred to HF nurse-led outpatient clinic. Our findings support the use of CRT-D vs. CRT-P in HFrEF, in particular with severely reduced EF.

- Background Beta-blockers reduce mortality and morbidity in heart failure (HF) with reduced ejection fraction (HFrEF). However, patients older than 80 years are poorly represented in randomized controlled trials. We assessed the association between beta-blocker use and outcomes in HFrEF patients aged amp;gt;= 80 years. Methods and results We included patients with an ejection fraction amp;lt;40% and aged amp;gt;= 80 years from the Swedish HF Registry. The association between beta-blocker use, all-cause mortality and cardiovascular (CV) mortality/HF hospitalization was assessed by Cox proportional hazard models in a 1:1 propensity score-matched cohort. To assess consistency, the same analyses were performed in a positive control cohort with age amp;lt;80 years. A negative control outcome analysis was run using hospitalization for cancer as endpoint. Of 6562 patients aged amp;gt;= 80 years, 5640 (86%) received beta-blockers. In the matched cohort including 1732 patients, beta-blocker use was associated with a significant reduction in the risk of all-cause mortality [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.79-0.99]. Reduction in CV mortality/HF hospitalization was not significant (HR 0.94, 95% CI 0.85-1.05) due to the lack of association with HF hospitalization, whereas CV death was significantly reduced. After adjustment rather than matching for the propensity score in the overall cohort, beta-blocker use was associated with reduced risk of all outcomes. In patients aged amp;lt;80 years, use of beta-blockers was associated with reduced risk of all-cause death (HR 0.79, 95% CI 0.68-0.92) and of the composite outcome (HR 0.88, 95% CI 0.77-0.99). Conclusions In HFrEF patients amp;gt;= 80 years of age, use of beta-blockers was high and was associated with improved all-cause and CV survival.

- OBJECTIVES This study assessed sex-related differences in a large cohort of unselected patients with heart failure (HF) across the ejection fraction (EF) spectrum. BACKGROUND Females are under-represented in randomized clinical trials. Potential sex-related differences in HF may question the generalizability of trials. METHODS In the Swedish Heart Failure Registry population multivariate Cox and logistic regression models were fitted to investigate differences in prognosis, prognostic predictors, and treatments across mates and females. RESULTS Of 42,987 patients, 37% were females (55% with HF with preserved EF [HFpEF], 39% with HF with mid-range EF [HFmrEF], and 29% with HF with reduced EF [HFrEF]). Females were older and more symptomatic and more likely to have hypertension and kidney disease but less likely to have diabetes and ischemic heart disease. After adjustments, females were more likely to use beta-blockers and digoxin but less likely to receive HF device therapy. Crude mortality/HF hospitalization rates for HFpEF (hazard ratio [HR]: 1.16) and HFmrEF (HR: 1.14) were significantly higher in females but lower in females with HFrEF (HR: 0.95). After adjustments, the risk was significantly tower in females regardless of EF (HR: 0.80 in HFrEF, HR: 0.91 in HFmrEF, and HR: 0.93 in HFpEF). The main sex-related differences in prognostic predictors concerned diabetes in HFrEF and anemia in HFmrEF. CONCLUSIONS Mates and females with HF showed different characteristics across the EF spectrum. Mates reported a lower crude risk of mortality/morbidity in HFpEF and HFmrEF but higher risk of HFrEF, although after adjustments, prognosis was better in females regardless of EF. The observed sex-related differences highlight the need for an adequate representation of females in HF randomized controlled trials to improve generatizabitity.

- Aims Left ventricular ejection fraction (EF) is required to categorize heart failure (HF) [i.e. HF with preserved (HFpEF), mid-range (HFmrEF), and reduced (HFrEF) EF] but is often not captured in population-based cohorts or non-HF registries. The aim was to create an algorithm that identifies EF subphenotypes for research purposes. Methods and results We included 42 061 HF patients from the Swedish Heart Failure Registry. As primary analysis, we performed two logistic regression models including 22 variables to predict (i) EF >= vs. <50% and (ii) EF >= vs. <40%. In the secondary analysis, we performed a multivariable multinomial analysis with 22 variables to create a model for all three separate EF subphenotypes: HFrEF vs. HFmrEF vs. HFpEF. The models were validated in the database from the CHECK-HF study, a cross-sectional survey of 10 627 patients from the Netherlands. The C-statistic (discrimination) was 0.78 [95% confidence interval (CI) 0.77-0.78] for EF >= 50% and 0.76 (95% CI 0.75-0.76) for EF >= 40%. Similar results were achieved for HFrEF and HFpEF in the multinomial model, but the C-statistic for HFmrEF was lower: 0.63 (95% CI 0.63-0.64). The external validation showed similar discriminative ability to the development cohort. Conclusions Routine clinical characteristics could potentially be used to identify different EF subphenotypes in databases where EF is not readily available. Accuracy was good for the prediction of HFpEF and HFrEF but lower for HFmrEF. The proposed algorithm enables more effective research on HF in the big data setting.

- Aims We aimed to derive and validate clinically useful clusters of patients with heart failure with preserved ejection fraction (HFpEF; left ventricular ejection fraction >= 50%). Methods and results We derived a cluster model from 6909 HFpEF patients from the Swedish Heart Failure Registry (SwedeHF) and externally validated this in 2153 patients from the Chronic Heart Failure ESC-guideline based Cardiology practice Quality project (CHECK-HF) registry. In SwedeHF, the median age was 80 [interquartile range 72-86] years, 52% of patients were female and most frequent comorbidities were hypertension (82%), atrial fibrillation (68%), and ischaemic heart disease (48%). Latent class analysis identified five distinct clusters: cluster 1 (10% of patients) were young patients with a low comorbidity burden and the highest proportion of implantable devices; cluster 2 (30%) patients had atrial fibrillation, hypertension without diabetes; cluster 3 (25%) patients were the oldest with many cardiovascular comorbidities and hypertension; cluster 4 (15%) patients had obesity, diabetes and hypertension; and cluster 5 (20%) patients were older with ischaemic heart disease, hypertension and renal failure and were most frequently prescribed diuretics. The clusters were reproduced in the CHECK-HF cohort. Patients in cluster 1 had the best prognosis, while patients in clusters 3 and 5 had the worst age- and sex-adjusted prognosis. Conclusions Five distinct clusters of HFpEF patients were identified that differed in clinical characteristics, heart failure drug therapy and prognosis. These results confirm the heterogeneity of HFpEF and form a basis for tailoring trial design to individualized drug therapy in HFpEF patients.
