Aims To investigate whether a heart failure (HF) hospitalization is associated with initiation/discontinuation of guideline-directed medical HF therapy (GDMT) and consequent outcomes.Methods and results Among patients in the Swedish HF registry with an ejection fraction <50% enrolled in 2009-2018, initiation/discontinuation of GDMT was investigated by assessing dispensations of GDMT in those with versus without a HF hospitalization. Of 14 737 patients, 6893 (47%) were enrolled when hospitalized for HF. Initiation of GDMT was more likely than discontinuation following a HF hospitalization compared to a control group of patients without a HF hospitalization (odds ratio range 2.1-4.0 vs. 1.4-1.6 for the individual medications), although the proportion of patients not on GDMT was still high (8.1-44.0%). Key patient characteristics triggering less use of GDMT (i.e. less initiation or more discontinuation) were older age and worse renal function. Following a HF hospitalization, initiation of renin-angiotensin system inhibitors/angiotensin receptor-neprilysin inhibitors or beta-blockers was associated with lower and their discontinuation with higher mortality risk, but no association with mortality was observed for initiation/discontinuation of mineralocorticoid receptor antagonists.Conclusions Following a HF hospitalization, initiation of GDMT was more likely than discontinuation, although still limited. Perceived or actual low tolerance were barriers to GDMT implementation. Early re-/initiation of GDMT was associated with better survival. Our findings represent a call for further implementing the current guideline recommendation for an early re-/initiation of GDMT following a HF hospitalization., Funding Agencies|Abbott; Swedish Heart and Lung Foundation; Abbott Vascular; Bayer; Pharmacosmos; [20220680]

Aims Use of implantable cardioverter-defibrillators (ICD) for primary prevention of sudden cardiac death (SCD) in heart failure with reduced ejection fraction (HFrEF) is limited. We aimed to investigate barriers to ICD use in HFrEF while considering the predicted risk of mortality and SCD. Method and results Patients from the SwedeHF registered in 2011-2018 and with an indication for primary prevention ICD were analysed. The Seattle Proportional Risk and Seattle Heart Failure Models were used to predict the proportional SCD and all-cause mortality risk, respectively. A multivariable logistic regression model was fitted to identify independent predictors of ICD use/non-use; Cox regression models to evaluate the interaction between predicted SCD/mortality risk and ICD use for mortality. Of 13 475 patients, only 15.5% had an ICD. Those with higher predicted proportional SCD risk (>45%) had an similar to 80% higher likelihood to have an ICD. Other predictors of non-use were follow-up in primary versus specialty care, higher comorbidity burden and lower socioeconomic status. ICD use was associated with lower mortality only in patients with higher predicted SCD and lower mortality risk (34% and 37% relative risk reduction for 3-year all-cause and cardiovascular mortality, respectively). In this subgroup of patients, underuse of ICD was 81.8%. Conclusion In a contemporary registry, only 15.5% of patients with an indication for primary prevention ICD received the device. While a high predicted proportional SCD risk was appropriately linked to ICD use, the lack of specialized follow-up, higher comorbidity burden, and lower socioeconomic status were major unjustified impediments to implementation. Our findings suggest areas for improving ICD use for primary prevention of SCD in clinical practice., Funding Agencies|Boston Scientific; EU/EFPIA Innovative Medicines Initiative 2 Joint Undertaking BigData@Heart grant [116074]

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.

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., Funding Agencies|Vifor Pharma

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., Funding Agencies|AstraZenecaAstraZeneca; EU/EFPIA Innovative Medicines Initiative 2 Joint Undertaking BigData@Heart grant [116074]; Swedish Research CouncilSwedish Research CouncilEuropean Commission [2019-01059]; Swedish Heart and Lung FoundationSwedish Heart-Lung Foundation

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.

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., Funding Agencies|Vifor Pharma
