Introduction: Data on temporal trends in guideline-based medical and device therapies in real-world chronic heart failure (HF) patients are lacking. Methods: Register-based nationwide follow-ups of temporal trends in characteristics, guideline-recommended therapies, one-year all-cause mortality, and HF rehospitalizations in incident HF patients in Denmark during 1996–2019. Results: Among 291,720 incident HF patients, the age at the onset of HF was stable over time. While initially fairly equal, the sex distribution markedly changed over time with more incidents occurring in men overall. Hypertension and diabetes increased significantly over time, while other comorbidities remained stable. Between 1996 and 2019, significant increases in angiotensin-converting enzyme inhibitor and angiotensin II-receptor blocker (ACEi/ARB) therapy (38.2% to 69.9%), beta-blocker therapy (15.5% to 70.6%), and mineralocorticoid receptor antagonist (MRA) therapy (11.8% to 34.5%) were seen. Angiotensin receptor-neprilysin inhibitor (ARNI) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) were introduced in the middle of the past decade, with minor increases but overall low uses: ARNI (2015: 0.1% vs. 2019: 3.9%) and SGLT2i (2012: <0.1% vs. 2019: 3.9%). Between 1999 and 2019, implantable cardioverter-defibrillator (ICD) use increased significantly: 0.1% to 3–4%. Cardiac resynchronization therapy (CRT) use similarly increased between 2000 and 2019: 0.2% to 2.3%. Between 1996 and 2019, one-year all-cause mortality decreased significantly: 34.6% to 20.9%, as did HF rehospitalizations (6% to 1.3%). Conclusions: Among 291,720 incident HF patients in Denmark during 1996–2019, significant increases in the use of ACEi/ARB, beta-blockers, MRAs, and devices were seen, with concurrent significant decreases in the one-year all-cause mortality and HF rehospitalization rates. The use of CRT, ARNI, and SGLT2i remained low, and MRAs were relatively underutilized, thereby representing future targe

Aims While clinical trials have suggested that a high ventricular rate is associated with increased risk of heart failure (HF) and mortality, all-comers studies are warranted. Objective To assess 1-year risk of new-onset diagnosed HF and all-cause mortality among rate-control treated patients presenting with atrial fibrillation (AF) on an electrocardiogram (ECG) according to ventricular rate. Methods and results ECGs recorded at the Copenhagen General Practitioners Laboratory (2001–15) were used to identify patients with AF. Multivariate Cox proportional hazard regression models were used to compare risk of new-onset HF and all-cause mortality after first ECG presenting with AF according to ventricular rate on ECG [<60, 60–79, 80–99, and 100–110, > 110 beats per minute (bpm)]. We identified 7408 patients in treatment with rate control drugs at time of first ECG presenting with AF [median age 78 years (Q1,Q3 = 70–85 years)], 45.8% male, median ventricular rate 83 bpm, (Q1,Q3 = 71–101 bpm)]. During 1-year follow-up, 666 (9.0%) of all patients with AF developed HF and 858 (11.6%) died. Patients with AF ventricular rates 100–110 bpm and >110 bpm had a hazard ratio (HR) of 1.46 (CI: 1.10–1.95) and 2.41 (CI: 1.94–3.00) respectively for new-onset HF, compared with 60–79 bpm. Similarly, patients with AF ventricular rates 100–110 bpm and >110 bpm had a HR of 1.44 (CI: 1.13–1.82) and 1.34 (CI: 1.08–1.65) respectively for all-cause mortality, compared with 60–79 bpm. Conclusions Ventricular rates ≥100 bpm among patients presenting with AF on ECG in treatment with rate control drugs were associated with greater risk of both new-onset HF and all-cause mortality., Aims While clinical trials have suggested that a high ventricular rate is associated with increased risk of heart failure (HF) and mortality, all-comers studies are warranted.

BACKGROUND: The mineralocorticoid receptor antagonists (MRAs) eplerenone and spironolactone are beneficial in heart failure with reduced ejection fraction (HFrEF), but have not been prospectively compared. We compared clinical outcomes, daily dosages, and discontinuation rates for the two drugs in a nationwide cohort.METHODS: We identified all patients with HFrEF in the period 2016-2020, who were alive and had initiated MRA treatment at study start, 180 days after HF diagnosis. We estimated the 2-year risk of a composite of death and HF hospitalization, as well as each component separately, using Kaplan-Meier, cumulative incidence functions, and Cox proportional hazards models adjusted for age, sex, and comorbidities. Secondly, we assessed treatment withdrawal, cross-over, and daily drug dosage.RESULTS: We included 7479 patients; 653 (9%) on eplerenone and 6840 (91%) on spironolactone. Patients in the eplerenone group were younger (median age 65 vs. 69 years), and more often men (91% vs. 68%), both P < 0.001. In adjusted analyses, with spironolactone as reference, there were no differences in the risk of the composite of all-cause death and HF hospitalization (HR 1.02, 95% CI 0.82-1.27), all-cause death (HR 0.93, 95% CI 0.67-1.30), or HF hospitalization (HR 1.10, 95% CI 0.84-1.42). Treatment withdrawal occurred in 34% in the eplerenone group and 53% in the spironolactone group (P < 0.001), treatment cross-over in 3%, and 10%, respectively. Daily dose >25 mg at 12 months, was observed in 230 patients (37%) in the eplerenone group and 771 patients (12%) in the spironolactone (P < 0.001).CONCLUSIONS: In a contemporary nationwide cohort of patients with new-onset HFrEF who initiated MRA, we found no differences in clinical outcomes associated with initiation of eplerenone vs. spironolactone. Treatment was more frequently withdrawn, and daily drug dosage was lower among patients treated with spironolactone.

Aims Myocardial infarction (MI) with cardiogenic shock (CS) and/or out-of-hospital cardiac arrest (OHCA) are conditions with potential loss of autonomy. In patients with MI, the association between CS and OHCA and need for home care or nursing home admission was examined. Methods and results Danish nationwide registries identified patients with MI (2008-19), who prior to the event lived at home without home care and discharged alive. One-year cumulative incidences and hazard ratios (HRs) were reported for home care need or nursing home admission, a composite proxy for disability in activities of daily living (ADL), along with all-cause mortality. The study population consisted of 67 109 patients with MI (by groups: -OHCA/-CS: 63 644; -OHCA/+CS: 1776; +OHCA/-CS: 968; and +OHCA/+CS: 721). The 1-year cumulative incidences of home care/nursing home were 7.1% for patients who survived to discharge with -OHCA/-CS, 20.9% for -OHCA/+CS, 5.4% for +OHCA/-CS, and 8.2% for those with +OHCA/+CS. The composite outcome was driven by home care. With the -OHCA/-CS as reference, the adjusted HRs for home care/nursing home were 2.86 (95% CI: 2.57-3.19) for patients with -OHCA/+CS; 1.31 (95% CI: 1.00-1.73) for + OHCA/-CS; and 2.18 (95% CI: 1.68-2.82) for those with +OHCA/+CS. The 1-year cumulative mortality were 5.1% for patients with -OHCA/-CS, 9.8% for -OHCA/+CS, 3.0% for +OHCA/-CS, and 3.4% for those with +OHCA/+CS. Conclusion In patients discharged alive after a MI, CS, and to a lesser degree OHCA were associated with impaired ADL with a two-fold higher 1-year incidence of home care or nursing home admission compared with MI patients without CS or OHCA.

BACKGROUND: Physical and mental well-being after critical illness may be objectified by the ability to work. We examined return to work among patients with myocardial infarction (MI) by cardiogenic shock (CS) status.METHODS: Danish nationwide registries were used to identify patients with first-time MI by CS status between 2005 and 2015, aged 18-63 years, working before hospitalization and discharged alive. Multiple logistic regression models were used to compare groups.RESULTS: We identified 19 799 patients with MI of whom 653 had CS (3%). The median age was similar for patients with and without CS (53 years, interquartile range 47-58). One-year outcomes in patients with and without CS were as follows: 52% vs. 83% returned to work, 41% vs. 16% did not and 6% vs. 1% died. The adjusted odds ratio (OR) of returning to work was 0.53 [95% confidence limit (CI): 0.42-0.66]. In patients with CS, males and patients surviving OHCA were more likely to return to work (OR: 1.83, 95% CI: 1.15-2.92 and 1.55, 95% CI: 1.00-2.40, respectively), whereas prolonged hospitalization (OR: 0.38, 95% CI: 0.22-0.65) and anoxic brain damage (OR: 0.36, 95% CI: 0.18-0.72) were associated with lower likelihood of returning to work.CONCLUSION: In patients with MI discharged alive, approximately 80% of those without CS returned to work at 1-year follow-up in contrast to 50% of those with CS. Among patients with CS, male sex and OHCA survivors were markers positively related to return to work, whereas prolonged hospitalization and anoxic brain damage were negatively related markers.

Objective: The aim of this study was to examine the long-term risk of heart failure (HF) and all-cause mortality, in patients discharged alive following hospitalization for myocarditis. Background. Prognosis in patients with apparently uncomplicated myocarditis is in general perceived as good, but data on long-term outcomes are sparse. Methods. From nationwide Danish registries we included patients without prior cardiac disease, discharged alive with a first-time diagnosis of myocarditis 1996–2016. Patients were matched 1:10 by age- and sex, with controls from the general population. Risk of HF hospitalization and death in cases and controls was compared by use of adjusted Cox regression analyses. Results. We identified 1557 patients with a first-time diagnosis of myocarditis, 72% men, median age 39 years. Patients with myocarditis had more hypertension, diabetes, and cancer, and received more pharmacotherapy prior to hospitalization compared to matched controls. During a mean follow-up of 8.5 years, the event rate of HF hospitalization was 8.7 vs. 2.2 per 1000 patient-years (py) in cases and controls; HR 4.59 (95% CI; 3.58–5.88) and for all-cause mortality, event rate 21.9 vs 11.2 per 1000 py; HR 2.10 (95% CI; 1.82–2.43). Among 784 patients with no events or HF medication one year after diagnosis, risk of HF hospitalization (HR 2.15; 95% CI; 1.18–3.92), and all-cause mortality (HR 1.62; 95% CI; 1.21–2.16) remained elevated compared to matched controls. Conclusion. Myocarditis in younger patients without prior cardiac disease was associated with a long-term excess risk of HF hospitalization, and death, even in patients free of events and HF medication 1 year after discharge.Highlights Myocarditis ranges from chest discomfort to severe heart failure. In most patients, left ventricular ejection fraction recovers but the long-term adverse cardiac risk is unknown. Patients with myocarditis and no prior cardiac disease were at higher risk of death and heart failure Ro

Background Patients with chronic diseases are at higher risk of requiring domiciliary and nursing home care, but how different chronic diseases compare in terms of risk is not known. We examined initiation of domiciliary care and nursing home admission among patients with heart failure (HF), stroke, COPD and cancer. Methods Patients with a first-time hospitalization for HF, stroke, COPD or cancer from 2008–2016 were identified. Patients were matched on age and sex and followed for five years. Results 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. Conclusions 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.

Background: Factors determining referral for advanced heart failure (HF) evaluation are poorly studied. We studied the influence of socioeconomic aspects on the referral process in Denmark, which has a taxpayer-funded national health care system. Methods: We identified all patients aged 18 to 75 years with a first diagnosis of HF during 2010 to 2018. Hospitalized patients had to be discharged alive and were then followed for the outcome of undergoing a right heart catheterization (RHC) used as a surrogate marker of advanced HF work-up. Results: Of 36 637 newly diagnosed patients with HF, 680 (1.9%) underwent RHC during the follow-up period (median time to RHC of 280 days [interquartile range, 73-914]). Factors associated with a higher likelihood of RHC included the highest versus lowest household income quartile (HR, 1.56 [95% CI, 1.18-2.05]; P=0.002), being diagnosed with HF at a tertiary versus nontertiary hospital (HR, 2.19 [95% CI, 1.84-2.61]; P<0.001) and during a hospitalization versus outpatient visit (HR, 1.65 [95% CI, 1.41-1.93]; P<0.001). Level of education, and occupational status were not independently associated with RHC. Older age, cancer, and a psychiatric diagnosis were independently associated with a decreased probability of RHC. Conclusions: Higher household income, HF diagnosis during hospitalization, and first admission at a tertiary hospital were associated with increased likelihood of subsequent referral for RHC independent of other demographic and clinical variables. Greater attention may be required to ensure timely referral for advanced HF therapies in lower income groups.

Aims: To evaluate the risk of heart failure (HF) in patients with type 2 diabetes (T2D) complicated by development of intercurrent ischaemic heart disease (IHD), end-stage renal disease (ESRD), or both, compared to patients with T2D and no IHD and ESRD. Methods and results: From Danish nationwide registries, we identified all patients with new-onset T2D with no history of HF between 1998 and 2015. Landmark analyses were used to estimate the 5-year absolute risk of HF at several follow-up times, and accounted for the occurrence of IHD and ESRD, identified before HF. The Aalen–Johansen estimator was used to account for censoring and the competing risk of death. A total of 285 024 patients with new-onset T2D were included. During follow-up, 19 960 developed incident HF. Among patients with T2D free of HF 5 years after T2D diagnosis, patients without IHD and ESRD had the lowest 5-year risk of HF [4.02%; 95% confidence interval (CI) 3.90–4.15), those with T2D complicated by IHD [11.51%; relative risk (RR) 2.86; 95% CI 2.72–3.02; P < 0.001] or ESRD (8.11%; RR 2.02; 95% CI 1.39–2.93; P < 0.001) an intermediate risk, and those with both IHD and ESRD (19.76%; RR 4.92; 95% CI 3.43–7.05; P < 0.001) the highest risk. Conclusion: Patients with T2D complicated by development of intercurrent IHD, ESRD, or both, showed a significantly higher risk of HF compared to those who did not develop IHD and ESRD. An effective way to delay or prevent the development of HF in patients with T2D may be to prevent IHD and ESRD.

BACKGROUND: It is estimated that 5% of patients with sarcoidosis have clinically manifest cardiac involvement, although autopsy and imaging studies suggest a significantly higher prevalence of cardiac involvement. There is a paucity of contemporary data on the risk of adverse cardiac outcomes, particularly heart failure (HF), in patients with sarcoidosis.OBJECTIVES: The purpose of this study was to examine the long-term risk of HF and other adverse cardiac outcomes in patients with sarcoidosis compared with matched control subjects.METHODS: In this cohort study, all patients age ≥18 years with newly diagnosed sarcoidosis (1996 to 2016) were identified through Danish nationwide registries and matched 1:4 by age, sex, and comorbidities with control subjects from the background population without sarcoidosis.RESULTS: Of the 12,042 patients diagnosed with sarcoidosis, 11,834 patients were matched with 47,336 subjects from the background population (median age: 42.8 years [25th to 75th percentile: 33.1 to 55.8 years], 54.3% men). The median follow-up was 8.2 years. Absolute 10-year risks of outcomes were as follows: HF: 3.18% (95% confidence interval [CI]: 2.83% to 3.57%) for sarcoidosis patients and 1.72% (95% CI: 1.58% to 1.86%) for the background population; the composite of ICD implantation, ventricular arrhythmias, and cardiac arrest: 0.96% (95% CI: 0.77% to 1.18%) for sarcoidosis patients and 0.45% (95% CI: 0.38% to 0.53%) for the background population; the composite of pacemaker implantation, atrioventricular block, and sinoatrial dysfunction: 0.94% (95% CI: 0.75% to 1.16%) for sarcoidosis patients and 0.51% (95% CI: 0.44% to 0.59%) for the background population; atrial fibrillation or flutter: 3.44% (95% CI: 3.06% to 3.84%) for sarcoidosis patients and 2.66% (95% CI: 2.49% to 2.84%) for the background population; and all-cause mortality: 10.88% (95% CI: 10.23% to 11.55%) for sarcoidosis patients and 7.43% (95% CI: 7.15% to 7.72%) for the b
