Abstract
AIM To assess cause-specific death in patients with heart failure with preserved, mildly reduced, and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF). METHODS AND RESULTS Data were analysed from the Swedish Heart Failure Registry (SwedeHF) and the National Patient Register of patients enrolled in SwedeHF 2000-2021. Cox proportional hazards regression models were performed and adjusted for age, sex and time period. Among 100 584 patients (23% HFpEF, 23% HFmrEF, 53% HFrEF), median age (interquartile range) was 75 (66-82) and 36% were female. Of those who died within 5 years, most deaths were ascribed to cardiovascular (CV) causes across all ejection fraction (EF) categories. Within 5 years, HFpEF had higher adjusted risk of non-CV death (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.28-1.38, p < 0.001) and lower adjusted risk of CV death (HR 0.85, 95% CI 0.82-0.88, p < 0.001) compared to HFrEF. Ischaemic heart disease (IHD) and cancer were the most common causes of CV and non-CV death regardless of EF category. The incidence rate of CV death due to IHD was highest in HFrEF while incidence rates of CV death due to pulmonary vascular disease, stroke, valvular heart disease and atrial fibrillation increased with increasing EF. The incidence rates of non-CV deaths due to cancer, respiratory disease, and infections increased with increasing EF. CONCLUSION Cardiovascular death was more common than non-CV death across all EF categories although the risk of non-CV death within 5 years was higher with increasing EF. IHD and cancer were the most common causes of CV and non-CV deaths, respectively, regardless of EF category.

Abstract
Abstract
Background
Comorbidities are associated with heart failure (HF) development, severity and outcomes, but may play different roles in HF with preserved (HFpEF) vs. mid-range (HFmrEF) vs. reduced ejection fraction (HFrEF). A detailed characterization of HF patients according to EF and comorbidities may improve prognostication and facilitate trial design.
Purpose
To investigate characteristics and outcomes in a large and unselected cohort of HF patients according to EF strata and presence/absence of concomitant type 2 diabetes (T2DM), atrial fibrillation (AF) and chronic kidney disease (CKD).
Methods
Patients enrolled in the Swedish HF registry between 2000–2012 were considered. Kaplan Meier curves and multivariable Cox regression models were fitted to assess risk and predictors of outcomes (HF and all-cause hospitalization; composite of cardiovascular (CV) death and HF hospitalization).
Results
Of 42,583 patients (23% HFpEF, 21% HFmrEF, 56% HFrEF), 24% had T2DM, 49% CKD defined as eGFR<60 ml/min/1.73m2, and 56% AF. T2DM, AF and CKD coexisted in 8% of the population with similar distribution across all EF strata. AF and CKD were the most likely to coexist. Prevalence of AF and/or CKD was highest in HFpEF and lowest in HFrEF, whereas prevalence of T2DM was similar across the EF spectrum (Figure). Compared to patients without T2DM and/or AF and/or CKD, those with any of them were more likely to suffer from other comorbidities (i.e. hypertension, anemia, COPD), to be inpatients, have more severe HF (higher NYHA class, NT-proBNP levels and use of diuretics, longer HF duration) but less likely to be followed-up in specialty vs. primary care. Concomitant history of ischemic heart disease was more likely in patients with vs. without CKD and/or T2DM but less likely in those with vs without AF.
Patients with vs. without T2DM and/or CKD and/or AF had worse prognosis. In particular, risk of HF hospitalization and composite of HF hospitalization/CV death was highest in patients with HFrEF and concomitant comorbidities, whereas the risk of all-cause hospitalization was highest in those with HFpEF or HFmrEF and concomitant comorbidities. Prognostic predictors of CV death/HF hospitalization were consistent in patients with T2DM, CKD or AF, regardless of EF (e.g. male sex, older age, lower EF category, more severe HF, ischemic heart disease, anemia, COPD).
Comorbidities burden
Conclusion
HF patients show a high burden of concomitant diseases, specifically T2DM, CKD and AF. CKD and AF are more prevalent in HFpEF vs. HFmrEF vs. HFrEF, whereas T2DM prevalence is consistent across the EF spectrum. Presence of comorbidities identifies patients with more severe HF regardless of EF category. Presence of comorbidities may identify patients at higher risk of CV outcomes in HFrEF and those at higher risk of non-CV events in HFpEF.
