Background Prevalent diabetes at the time of heart failure (HF) diagnosis is associated with a higher risk of death, but the incidence and prognostic importance of new-onset diabetes in patients with established HF remains unknown. Methods Patients with a first hospitalization for HF in the period 2003–2014 were included and stratified according to history of diabetes. Annual incidence rates of new-onset diabetes were calculated and time-dependent multivariable Cox regression models were used to compare the risk of death in patients with prevalent and new-onset diabetes with patients without diabetes as reference. The model was adjusted for age, sex, duration of HF, educational level and comorbidity. Covariates were continuously updated throughout follow-up. Results A total of 104,522 HF patients were included in the study, of which 21,216 (19%) patients had diabetes at baseline, and 8164 (10%) developed new-onset diabetes during a mean follow-up of 3.9 years. Patients with new-onset diabetes and prevalent diabetes were slightly younger than patients without diabetes (70 vs. 74 and 77, respectively), more likely to be men (62% vs. 60% and 54%), and had more comorbidities expect for ischemic heart disease, hypertension and chronic kidney disease which were more prevalent among patients with prevalent diabetes. Incidence rates of new-onset diabetes increased from around 2 per 100 person-years in the first years following HF hospitalization up to 3 per 100 person-years after 5 years of follow-up. A total of 61,424 (59%) patients died during the study period with event rates per 100 person-years of 21.5 for new-onset diabetes, 17.9 for prevalent diabetes and 13.9 for patients without diabetes. Compared to patients without diabetes, new-onset diabetes was associated with a higher risk of death (adjusted HR 1.47; 95% CI 1.42–1.52) and prevalent diabetes was associated with an intermediate risk (HR 1.19; 95% CI, 1.16–1.21). Conclusion Following the first HF hospitalization, the incidence of new-onset diabetes was around 2% per year, rising to 3% after 5 years of follow-up. New-onset diabetes was associated with an increased risk of death, compared to HF patients with prevalent diabetes (intermediate risk) and HF patients without diabetes.

Angiotensin converting enzyme inhibitors (ACE-I), are beneficial both in heart failure with reduced ejection fraction (HF-REF) and after myocardial infarction (MI). We examined the effects of the angiotensin-receptor neprilysin inhibitor sacubitril/valsartan, compared with the ACE-I enalapril, on coronary outcomes in PARADIGM-HF. We examined the effect of sacubitril/valsartan compared with enalapril on the following outcomes: i) the primary composite endpoint of cardiovascular (CV) death or HF hospitalization, ii) a pre-defined broader composite including, in addition, MI, stroke, and resuscitated sudden death, and iii) a post hoc coronary composite of CV-death, non-fatal MI, angina hospitalization or coronary revascularization. At baseline, of 8399 patients, 3634 (43.3%) had a prior MI and 4796 (57.1%) had a history of any coronary artery disease. Among all patients, compared with enalapril, sacubitril/valsartan reduced the risk of the primary outcome (HR 0.80 [0.73–0.87], P<.001), the broader composite (HR 0.83 [0.76–0.90], P<.001) and the coronary composite (HR 0.83 [0.75–0.92], P<.001). Although each of the components of the coronary composite occurred less frequently in the sacubitril/valsartan group, compared with the enalapril group, only CV death was reduced significantly. Compared with enalapril, sacubitril/valsartan reduced the risk of both the primary endpoint and a coronary composite outcome in PARADIGM-HF. Additional studies on the effect of sacubitril/valsartan on atherothrombotic outcomes in high-risk patients are merited.

111,144 patients, 27,786 with each disease, were identified. The median age was 69 years and two thirds of the patients were men. The 5-year risk of receiving domiciliary care was; HF 20.9%, stroke 25.2%, COPD 24.6% and cancer 19.3%. The corresponding adjusted hazard ratios (HRs), with HF patients used as reference, were: stroke 1.35[1.30-1.40]; COPD 1.29[1.25-1.34]; and cancer 1.19[1.14-1.23]. The five-year incidence of nursing home admission was 6.6% for stroke, and substantially lower in patients with HF(2.6%), COPD(2.6%) and cancer (1.5%). The adjusted HRs were (HF reference): stroke, 2.44 [2.23-2.68]; COPD 1.01 [0.91-1.13] and cancer 0.76 [0.67-0.86]. Living alone, older age, diabetes, chronic kidney disease, depression and dementia predicted a higher likelihood of both types of care. In patients with HF, stroke, COPD or cancer 5-year risk of domiciliary care and nursing home admission, ranged from 19-25% and 1-7%, respectively. Patients with stroke had the highest rate of domiciliary care and were more than twice as likely to be admitted to a nursing home, compared to patients with the other conditions.

Purpose Self-assessed poor health status is associated with increased risk of mortality in several cardiovascular conditions, but has not been investigated in patients with endocarditis. We examined health status and mortality in patients with endocarditis. Methods This is a re-specified substudy of the randomized POET endocarditis trial, which included 400 patients. Patients completed the single-question self-assessed health status from the Short-Form 36 questionnaire at time of randomization and were categorized as having poor or non-poor (excellent/very good, good, or fair) health status. Self-assessed health status and all-cause mortality were examined by a Cox regression model. Results Self-assessed health status was completed by 266 (67%) patients with a mean age of 68.0 years (± 11.8), 54 (20%) were females, and 86 (32%) had one or more major concurrent medical conditions besides endocarditis. The self-assessed health status distribution was poor ( n  = 21, 8%) and non-poor ( n  = 245, 92%). The median follow-up was 3.3 years and death occurred in 9 (43%) and 48 (20%) patients reporting poor and non-poor health status, respectively, and mortality rates [mortality/100 person-years, 95% confidence interval (CI)] were 18.1 (95% CI 9.4–34.8) and 5.4 (95% CI 4.1–7.2), i.e., the crude hazard ratio for death was 3.4 (95% CI: 1.7–7.0, p  < 0.01). Conclusion Self-assessed poor health status compared with non-poor health status as assessed by a single question was associated with a threefold increased long-term mortality in patients with endocarditis.

Familial hypercholesterolemia (FH) is a common genetic disorder causing accelerated atherosclerosis and premature cardiovascular disease. The aim of this study was to examine the prevalence and prognostic significance of possible FH in patients with myocardial infarction (MI). By individual-level linkage of data from the Eastern Danish Heart Registry and national administrative registries, a study population of patients referred for coronary angiography due to MI was selected. The study population was divided into “unlikely FH” and “possible FH” based on the Dutch Lipid Clinic Network criteria, which included a plasma low-density lipoprotein cholesterol (LDL-C) and age for onset of cardiac disease. A score of ≥3 points was used as the cutpoint between the 2 groups. Among the study population of 13,174 MI patients, 1,281 (9.7%) had possible FH. These patients were younger (59.1 vs 65.7 years, P ≤ .0001), had similar levels of comorbidities, and were treated more aggressively with cholesterol-lowering drugs compared with patients with unlikely FH. During a median of 3.3 years of follow-up, the unadjusted and adjusted event rates of recurrent MI were higher in patients with possible FH compared with unlikely FH (16% vs 11%, adjusted hazard ratio 1.28, 95% CI 1.09-1.51, P = .003.). Differences in adjusted all-cause mortality were not statistically significant (17% vs 23%, adjusted hazard ratio 0.89 [0.74-1.04], P = .1). We found that MI patients with possible FH have higher risk of recurrent MI but similar risk of mortality compared with unlikely FH patients. Further studies on secondary prevention are warranted.

Heart failure (HF) has a major impact on a patient's quality of life and functional status. This impact may be sufficiently profound to prevent independent living although how often this is the case is unknown. We examined the need for domiciliary assistance and admission to a nursing home following first HF hospitalization. In nationwide Danish registries, we identified a cohort of patients discharged alive after a first-time HF hospitalization in the period 2008-2014 who were matched 1:5 with comparison subjects based on age and sex and followed for 5 years. We included 37,547 patients (69% men) discharged after a first-time HF-hospitalization and 187,735 comparison subjects. The 5-year incidence of initiation of domiciliary care was 24.1% [23.7%-24.6%] among HF patients and 9.2% [9.1%-9.4%] among the comparison cohort and yielded a corresponding adjusted HR of 2.02 [1.96-2.09]. Covariates associated with initiation of domiciliary support included older age (HR 1.08 [1.07-1.08] per 1 year increase in age), living alone (HR 2.09 [2.04-2.15]) and comorbidities. The 5-year incidence of nursing home admission was 3.9% [3.7%-4.0%] among HF patients and 1.7% [1.7%-1.8%] among the comparison cohort and this resulted in an adjusted HR of 1.91 [1.77-2.06]. Covariates associated with nursing home admission included older age (HR 1.10 [1.10-1.11]), living alone (HR 2.15 [2.02-2.28]) and history of stroke (HR 2.71 [2.53-2.90]). Hospitalization for HF is associated with increased need for domiciliary support and nursing home admissions. Older age, living alone, and comorbidities were associated with higher risk of both outcomes.

Aims/hypothesis Individual sulfonylureas (SUs) and metformin have, in some studies, been associated with unequal hypoglycaemic, cardiovascular and mortality risks when used as monotherapy in type 2 diabetes. We investigated the outcomes in patients treated with different combinations of SUs and insulin vs a combination of metformin and insulin in a retrospective nationwide study. Methods All Danish individuals using dual therapy with SU + insulin or metformin + insulin without prior myocardial infarction (MI) or stroke were followed from 1 January 1997 to 31 December 2009 in nationwide registries. Risks of all-cause mortality, cardiovascular death, hypoglycaemia and a composite endpoint of MI, stroke and cardiovascular death were compared. Rate ratios (RR) [95% CIs] were calculated using time-dependent multivariable Poisson regression analysis. Results A total of 11,081 patients used SU + insulin and 16,910 used metformin + insulin. Patients receiving metformin + insulin were younger and had less comorbidity and a longer history of glucose-lowering treatment. SU + insulin was associated with higher mortality rates compared with metformin + insulin (76–126 vs 23 per 1,000 person-years). In adjusted analyses, SU + insulin was associated with increased all-cause mortality (RR 1.81 [1.63, 2.01]), cardiovascular death (RR 1.35 [1.14, 1.60]) and the composite endpoint (RR 1.25 [1.09, 1.42]) compared with metformin + insulin. Hypoglycaemia was more frequent with SU + insulin than with metformin + insulin (17–23 vs six events per 1,000 person-years) and was associated with increased mortality (RR 2.13 [1.97, 2.37]). There were no significant differences in risk between individual SUs in combination with insulin. Conclusions/interpretation In combination with insulin, the use of SUs was associated with increased mortality compared with metformin. There were no significant risk differences between SUs.

Purpose The “distressed” (Type D) personality trait has been reported to be over-represented in patients with heart failure (HF) compared to the background population and may provide prognostic information for mortality. We examined the association between Type D personality and outcomes in the DANISH trial (The Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators in Patients with Non-ischemic Systolic Heart Failure on Mortality). Methods The DANISH trial included a total of 1116 patients with non-ischemic HF on guideline-recommended therapy. Type D personality was assessed with the Type D Scale (DS14) at baseline and investigated through follow-up accordingly. Multivariable Cox proportional hazard models were used to compare hazard ratios (HR) of cardiovascular and all-cause mortality. Results Type D personality assessment was completed by 873 (78%) patients at baseline and Type D personality was found in 120 (14%) patients. The median follow-up was 67 months (interquartile range [IQR] 48–83). Among patients with versus without Type D personality, 22% versus 19% died from all-cause yielding similar incidence rates of 4.62 (95% CI 3.14–6.87) versus 3.95 (95% CI 3.37–4.66) per 100 person-years. The adjusted risk of all-cause mortality was not significantly different in patients with versus without Type D personality with an adjusted HR of 1.31 (95% CI 0.84–2.03, p  = 0.23) with similar results for cardiovascular death (HR 1.46 (95% CI 0.88–2.44, p  = 0.15). Conclusion Type D personality was not significantly associated with increased risk of all-cause mortality or cardiovascular death in patients with non-ischemic HF.

Type 1 diabetes is associated with increased cardiovascular (CV) morbidity and mortality, and cardiovascular autonomic neuropathy (CAN) is an important CV risk factor. The study aimed to explore associations between CAN and altered cardiac chamber sizes in persons with type 1 diabetes. This was a cross-sectional study of 71 asymptomatic, normoalbuminuric participants with long-term type 1 diabetes (39 with CAN, determined by >1 abnormal autonomic function test) examined with cardiac multi detector computed tomography scans, which allowed measurements of left ventricular mass and all four cardiac chamber volumes. Cardiac chambers were indexed according to body surface area (ml/m2 or g/m2). Persons with and without CAN had mean ± SD age of 57 ± 7 and 50 ± 8 years (p < 0.001) and diabetes duration of 36 ± 11 and 32 ± 9 years (p < 0.05), respectively. Increasing autonomic dysfunction, evaluated by decrease in heart rate variability during deep breathing (in beats per minute), was associated with larger right (−0.5, 95% CI −1.0 to −0.0, p < 0.05) and trend towards larger left (−0.4, 95% CI −0.8–0.0, p < 0.1) ventricular volumes in multivariable linear regression. Our results suggest that impaired autonomic function may be associated with modest enlargement of ventricular volumes; this might be an early sign of progression towards heart failure.

Abstract Aims Current treatment guidelines recommend implantable cardioverter-defibrillators (ICDs) in eligible patients with an estimated survival beyond 1 year. There is still an unmet need to identify patients who are unlikely to benefit from an ICD. We determined cause-specific 1-year mortality after ICD implantation and identified associated risk factors. Methods and results Using Danish nationwide registries (2000–2017), we identified 14 516 patients undergoing first-time ICD implantation for primary or secondary prevention. Risk factors associated with 1-year mortality were evaluated using multivariable logistic regression. The median age was 66 years, 81.3% were male, and 50.3% received an ICD for secondary prevention. The 1-year mortality rate was 4.8% (694/14 516). ICD recipients who died within 1 year were older and more comorbid compared to those who survived (72 vs. 66 years, P < 0.001). Risk factors associated with increased 1-year mortality included dialysis [odds ratio (OR): 3.26, confidence interval (CI): 2.37–4.49], chronic renal disease (OR: 2.14, CI: 1.66–2.76), cancer (OR: 1.51, CI: 1.15–1.99), age 70–79 years (OR: 1.65, CI: 1.36–2.01), and age ≥80 years (OR: 2.84, CI: 2.15–3.77). The 1-year mortality rates for the specific risk factors were: dialysis (13.8%), chronic renal disease (13.1%), cancer (8.5%), age 70–79 years (6.9%), and age ≥80 years (11.0%). Overall, the most common causes of mortality were related to cardiovascular diseases (62.5%), cancer (10.1%), and endocrine disorders (5.0%). However, the most common cause of death among patients with cancer was cancer-related (45.7%). Conclusion Among ICD recipients, mortality rates were low and could be indicative of relevant patient selection. Important risk factors of increased 1-year mortality included dialysis, chronic renal disease, cancer, and advanced age.
