Incidence of clinical outcomes in heart failure patients with and without advanced chronic kidney disease.

AIMS: Chronic kidney disease (CKD) is a well-established risk factor for heart failure (HF); however, patients with an estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2 have been systematically excluded from clinical trials. This study investigated the incidence of HF and kidney outcomes in HF patients with and without advanced CKD, that is, eGFR < 30. METHODS: From nationwide registries, HF patients were identified from 2014 to 2018 and categorized into three groups according to baseline eGFR (eGFR ≥ 60, 60 > eGFR ≥ 30 and eGFR < 30). The incidence of primary outcomes (all-cause mortality, HF hospitalization, end-stage kidney disease and sustained 50% eGFR decline) was estimated using cumulative incidence functions. RESULTS: Of the 21 959 HF patients included, the median age was 73.9 years, and 30% of patients had an eGFR between 30 and 60 and 7% had an eGFR < 30. The 4 year incidence of all-cause mortality was highest for patients with eGFR < 30 (28.3% for patients with eGFR ≥ 60, 51.6% for patients with 60 > eGFR ≥ 30 and 72.2% for patients with eGFR < 30). The 4 year incidence of HF hospitalization was comparable between the groups (25.8%, 29.8% and 26.1% for patients with eGFR ≥ 60, 60 > eGFR ≥ 30 and eGFR < 30, respectively). For patients with eGFR < 30, kidney outcomes were four times more often the first event than patients with eGFR > 30 (4 year incidence of kidney outcome as the first event was 5.0% for eGFR ≥ 60, 4.8% for 60 > eGFR ≥ 30 and 20.1% for eGFR < 30). CONCLUSIONS: Patients with advanced CKD had a higher incidence of mortality and poorer kidney outcomes than those without advanced CKD, but a similar incidence of HF hospitalizations.

Prognostic Impact of Anemia in Patients Undergoing Aortic Valve Replacement: A Nationwide Study.

BACKGROUND: Patients undergoing aortic valve replacement (AVR) have high readmission rates. Several risk factors have been proposed as potential modifiable targets, including anemia. We examined the association between anemia at discharge and subsequent outcomes in these patients. METHODS: Using Danish nationwide registries, we identified all patients who underwent AVR between 2015-2021, were alive at discharge (index date), and had an available hemoglobin (Hb) measurement taken between procedure and discharge. Patients were categorized as having i) moderate/severe anemia (Hb<6.2 mmol/L) or ii) no/mild anemia (Hb≥6.2 mmol). The one-year rates of all-cause mortality, all-cause hospital admission, heart failure (HF) admission, and atrial fibrillation (AF) admission were compared using multivariable Cox regression models. RESULTS: 8,614 patients were identified; 2,847 (33.1%) had moderate/severe anemia (60.2% male, median age 74) and 5,767 (66.9%) had no/mild anemia (68.0% male, median age 76). For these two groups, respectively, the cumulative one-year incidences of the outcomes were: i) all-cause mortality: 5.1% vs. 4.3%; ii) all-cause admission: 53.8% vs. 47.5%; iii) AF admission: 14.0% vs. 11.6%); iv) HF admission: 6.8% vs. 6.2%. In adjusted analysis, moderate/severe anemia, compared with no/mild anemia, was associated with higher rates of all-cause mortality (hazard ratio (HR) 1.27 [95%CI 1.02-1.58]), all-cause admission (HR 1.22 [95%CI 1.14-1.30]), and AF admission (HR 1.23 [95%CI 1.08-1.40]), but not HF admission (HR 1.09 [95%CI 0.91-1.31]). CONCLUSION: In patients undergoing AVR, moderate/severe anemia at discharge, compared with no/mild anemia, was associated with increased all-cause mortality, all-cause hospital admission, and AF admission, but not HF admission, at one-year post-discharge.

Heart Failure Events After Long-term Continuous Screening for Atrial Fibrillation: Results From the Randomized LOOP Study.

BACKGROUND: Mounting evidence indicates that even device-detected subclinical atrial fibrillation is associated with a higher risk of heart failure (HF). However, the potential impact of atrial fibrillation screening on HF remains unknown. METHODS: The LOOP Study (Atrial Fibrillation detected by Continuous ECG Monitoring using Implantable Loop Recorder to prevent Stroke in High-risk Individuals) evaluated the effects of atrial fibrillation screening on stroke prevention using an implantable loop recorder (ILR) versus usual care in elderly individuals with additional stroke risk factors. In this secondary analysis, we explored the following HF end points: (1) HF event or cardiovascular death; (2) HF event; (3) event with HF with reduced ejection fraction (HFrEF); and (4) HFrEF event or cardiovascular death. Outcomes were assessed in a Cox model both as time-to-first events and as total (first and recurrent) events analyzed using the Andersen-and-Gill method. RESULTS: Of 6004 participants (mean age 74.7 and 52.7% men), 1501 were randomized to ILR screening and 4503 to the control group. In total, 77 (5.1%) in the ILR group versus 295 (6.6%) in the control group experienced the primary outcome of an HF event or cardiovascular death. Compared with usual care, ILR screening was associated with a nonsignificant reduction in the primary outcome for the time-to-first event analysis (hazard ratio, 0.78 [95% CI, 0.61-1.01]) and the total event analysis (hazard ratio, 0.77 [95% CI, 0.59-1.01]). Similar results were obtained for the HF event. A significant risk reduction in total events was observed in the ILR group for the composite of HFrEF event or cardiovascular death and for HFrEF event (hazard ratio, 0.74 [95% CI, 0.56-0.98] and 0.65 [95% CI, 0.44-0.97], respectively). CONCLUSIONS: In an elderly population with stroke risk factors, ILR screening for atrial fibrillation tended to be associated with a lower rate of total HF events and cardiovascular death, particularly those related to HFrEF. These findings should be considered hypothesis-generating and warrant further investigation. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02036450.

Effects of dapagliflozin according to QRS duration across the spectrum of left ventricular ejection fraction: An analysis of DAPA-HF and DELIVER.

AIMS: The primary aim was to evaluate the effect of dapagliflozin according to QRS duration across the spectrum of left ventricular ejection fraction (LVEF), given that prolongation of QRS duration is associated with less favourable ventricular remodelling with pharmacological therapy and worse outcomes. METHODS AND RESULTS: A pooled analysis of the DAPA-HF and DELIVER trials, excluding patients with a paced rhythm and cardiac resynchronization therapy. Overall, 4008 patients had heart failure (HF) with reduced ejection fraction (HFrEF), and 5816 had HF with mildly reduced/preserved ejection fraction (HFmrEF/HFpEF). QRS duration was <120 ms in 7039 patients (71.7%), 120-149 ms in 1725 (17.6%), and ≥150 ms in 1060 patients (10.8%). The median follow-up time was 23 months. The rate of the primary composite outcome of cardiovascular death or worsening HF was 9.2 (95% confidence interval [CI] 8.7-9.7), 14.3 (13.0-15.7), and 15.9 (14.1-17.9) per 100 patient-years in the <120, 120-149, and ≥150 ms groups, respectively. This gradient in event rates was observed both in HFrEF and HFmrEF/HFpEF. Dapagliflozin, compared with placebo, reduced the risk of the primary outcome consistently across the QRS duration subgroups (hazard ratio [95% CI] 0.75 [0.67-0.85], 0.79 [0.65-0.96], and 0.89 [0.70-1.13] in the <120, 120-149, and ≥150 ms groups, respectively; p for interaction = 0.28). The effect of dapagliflozin on the primary outcome was consistent across the QRS duration regardless of HF phenotype that is, HFrEF or HFmrEF/HFpEF. CONCLUSIONS: Prolongation of QRS duration is associated with worse outcomes irrespective of HF phenotype. Dapagliflozin reduced the risk of the primary outcome, regardless of QRS duration, in DAPA-HF and DELIVER.

Aortic dimensions in women with previous pre-eclampsia.

BACKGROUND: Pre-eclampsia is a pregnancy related disorder associated with hypertension and vascular inflammation, factors that are also involved in the pathological pathway of aortic dilatation and aneurysm development. It is, however, unknown if younger women with previous pre-eclampsia have increased aortic dimensions. We tested the hypothesis that previous pre-eclampsia is associated with increased aortic dimensions in younger women. METHODS: The study was a cross-sectional cohort study of women with previous pre-eclampsia, aged 40-55, from the PRECIOUS population matched by age and parity with women from the general population. Using contrast-enhanced CT, aortic diameters were measured in the aortic root, ascending aorta, descending aorta, at the level of the diaphragm, suprarenal aorta, and infrarenal aorta. RESULTS: 1355 women (684 with previous pre-eclampsia and 671 from the general population), with a mean (standard deviation) age of 46.9 (4.4) were included. The pre-eclampsia group had larger mean (standard deviation) aortic diameters (mm) in all measured segments from the ascending to the infrarenal aorta (ascending: 33.4 (4.0) vs. 31.4 (3.7), descending: 23.9 (2.1) vs. 23.3 (2.0), diaphragm: 20.8 (1.8) vs. 20.4 (1.8), suprarenal: 22.9 (1.9) vs. 22.0 (2.0), infrarenal: 19.3 (1.6) vs. 18.6 (1.7), p â€‹< â€‹0.001 for all, also after adjustment for age, height, parity, menopause, dyslipidemia, smoking and chronic hypertension. Guideline-defined ascending aortic aneurysms were found in 8 vs 2 women (p â€‹= â€‹0.12). CONCLUSIONS: Women with previous pre-eclampsia have larger aortic dimensions compared with women from the general population. Pre-eclampsia was found to be an independent risk factor associated with a larger aortic diameter.

Association of multiple sclerosis with incident diabetes: A nationwide cohort study.

AIM: Diabetes mellitus (DM) and multiple sclerosis (MS) are two common diseases known to worsen the trajectory of each other, yet it is unknown whether MS is associated with incident DM. METHODS: Using Danish nationwide registries, we identified all patients aged 18-99 with a first-time primary or secondary discharge diagnosis with MS between 2000 and 2018, with no known DM. These patients were matched with control subjects from the background population in a 1:5 ratio based on age and sex, to assess their risk of DM. RESULTS: A total of 13,376 patients with MS and 66,880 matched control subjects were included (33 % men; median age, 42 years [25th-75th percentile, 33-51]). During a median follow-up of 8.3 years (25th-75th percentile, 4.0-13.3), 467 (3.5 %) patients with MS and 2397 (3.6 %) control subjects were diagnosed with DM. The cumulative incidence of DM was similar among patients with MS and control subjects (95 % confidence interval [CI] 6.5 % [5.7-7.2 %] vs. 7.3 % [95 % CI 6.9-7.9 %], respectively), and adjusted analysis yielded a hazard ratio (HR) of 0.98 [95 % CI 0.89-1.09]). The overall risk of incident type 1 diabetes was low and yielded a HR of 1.60 [95 % CI 0.98-1.40] in patients with MS compared with control subject (P = 0.07). CONCLUSION: This study demonstrated that patients with MS had a similar risk of incident DM as compared to age- and sex matched controls from the background population.

Temporal changes in the number of European and American guideline recommendations and underlying evidence base for the management of infective: An update of previous published data.

This report aimed to examine temporal changes in the number of recommendations on management of infective endocarditis in the European and American guidelines. The number of recommendations has increased since 2004 without an increment in evidence base in the European iteration. American guidelines have reduced the number of recommendations with a main evidence base of level B.

Long-Term Cardiovascular Risk Associated With Treatment of Attention-Deficit/Hyperactivity Disorder in Adults.

BACKGROUND: Incrementing numbers of patients treated for attention-deficit/hyperactivity disorder (ADHD) call for scrutiny concerning long-term drug-safety. OBJECTIVES: This study aims to investigate associations between long-term use of ADHD treatment and cardiovascular outcomes. METHODS: Using nationwide registers, adult patients first-time initiated on ADHD treatment between 1998 and 2020 were identified. Exposure groups were prior users, <1 defined daily dose (DDD) per day, ≥1 DDD per day determined at start of follow-up, and 1 year after patients' first claimed prescription. Outcomes were acute coronary syndromes, stroke, heart failure, and a composite of the above. RESULTS: At start of follow-up, 26,357, 31,211, and 15,696 individuals were correspondingly categorized as prior users (42% female, median age: 30 years [Q1-Q3: 23-41 years]), <1 DDD per day (47% female, median age: 31 years [Q1-Q3: 24-41 years]), and ≥1 DDD per day (47% female, median age: 33 years [Q1-Q3: 25-41 years]), respectively. Comparing ≥1 DDD per day with prior users, elevated standardized 10-year absolute risk of stroke (2.1% [95% CI: 1.8%-2.4%] vs 1.7% [95% CI: 1.5%-1.9%]), heart failure (1.2% [95% CI: 0.9%-1.4%] vs 0.7% [95% CI: 0.6%-0.8%]), and the composite outcome (3.9% [95% CI: 3.4%-4.3%] vs 3.0% [95% CI: 2.8 %-3.2%]) was found-with corresponding risk ratios of 1.2 (95% CI: 1.0-1.5), 1.7 (95% CI: 1.3-2.2), and 1.3 (95% CI: 1.1-1.5). No apparent associations were found for acute coronary syndrome (1.0% [95% CI: 0.8%-1.2%] vs 0.9% [95% CI: 0.8%-1.0%]). CONCLUSIONS: Possible associations between elevated long-term cardiovascular risk and increasing dosage of ADHD treatment use in a young patient group should warrant further investigation.

N-terminal pro-B-type natriuretic peptide levels pre-transcatheter aortic valve implantation and relationship with long-term outcomes.

Background: Blood levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) has been suggested as a future guidance tool for the selection of patients for aortic valve replacement. This study aimed to examine how levels of NT-proBNP pre-transcatheter aortic valve implantation (TAVI) is associated with one-year rates of heart failure (HF) admission and mortality following TAVI. Methods: With Danish nationwide registries, we identified all patients undergoing TAVI from 2014 to 2021 who had at least one recorded NT-pro-BNP measurement within one year before TAVI. Patients were compared by quartiles of pre-TAVI NT-proBNP: quartile 4 (high NT-proBNP group) vs quartile 1-3 (low NT-proBNP group). Comparisons of all-cause mortality and HF-admissions were conducted using Kaplan-Meier analysis, cumulative incidence, and Cox analysis, as appropriate. Results: We identified 1,140 patients undergoing first-time TAVI with a recorded NT-pro-BNP; 846 (74.2 %) with a low NT-proBNP (<420 pmol/L) (55.0 % male, median age 81 year) and 294 (25.8 %) with a high NT-proBNP (≥420 pmol/L) (53.1 % male, median age 82 year). A high versus low NT-proBNP was associated with increased one-year cumulative incidence of HF-admissions (9.1 % vs. 23.1 %, adjusted HR 2.00 [95 % CI, 1.40-2.85]) and all-cause mortality (6.0 % vs. 14.6 %, adjusted HR 1.95 [95 % CI: 1.24-3.07]). A high NT-proBNP was associated with higher rates of outcomes irrespective of previously known atrial fibrillation, HF, chronic kidney disease, and hypertension. Conclusion: In patients undergoing TAVI, a baseline NT-proBNP ≥ 420 pmol/L was associated with increased one-year rates of HF-admission and mortality post-TAVI and may be utilized to identify a high-risk population.

Balcinrenone plus dapagliflozin in patients with heart failure and chronic kidney disease: Results from the phase 2b MIRACLE trial.

AIMS: Many patients with heart failure (HF) have chronic kidney disease (CKD) and may not tolerate mineralocorticoid receptor antagonists. We investigated the efficacy and safety of the novel mineralocorticoid receptor modulator balcinrenone in combination with dapagliflozin in a phase 2b study. METHODS AND RESULTS: From January 2021 to October 2023, we randomized 133 adults with symptomatic HF, ejection fraction <60%, estimated glomerular filtration rate (eGFR) ≥30 to ≤60 ml/min/1.73 m2 and urinary albumin-to-creatinine ratio (UACR) ≥30 to <3000 mg/g, to receive balcinrenone 15, 50 or 150 mg/day plus dapagliflozin 10 mg/day, or dapagliflozin 10 mg/day plus placebo, for 12 weeks. Enrolment was stopped early because of slow recruitment. Relative reductions in UACR from baseline to week 12 (primary endpoint) were not significantly different between the balcinrenone plus dapagliflozin groups versus dapagliflozin plus placebo. There was no clear balcinrenone dose-response relationship. There were possible dose-dependent increases in serum potassium levels, reduced eGFR in the highest dose group, and non-significant trends towards reduced N-terminal pro-B-type natriuretic peptide levels. Hyperkalaemia adverse events led to discontinuation in two participants receiving balcinrenone plus dapagliflozin and none in those receiving dapagliflozin plus placebo. CONCLUSION: While the smaller than planned sample size limits interpretation, we did not see significant reduction in UACR in patients treated with balcinrenone plus dapagliflozin compared with dapagliflozin plus placebo.

New York Heart Association functional class and implantable cardioverter-defibrillator in non-ischaemic heart failure with reduced ejection fraction: Extended follow-up of the DANISH trial.

AIMS: Current guidelines recommend implantable cardioverter-defibrillator (ICD) therapy in patients with heart failure, a left ventricular ejection fraction of ≤35%, and New York Heart Association (NYHA) class II-III. However, the evidence regarding the benefit of primary prevention ICD is less consistent in patients with NYHA class III. We investigated the long-term effects of primary prevention ICD implantation according to NYHA class in an extended follow-up study of the DANISH trial. METHODS AND RESULTS: The DANISH trial randomized 1116 patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF) to ICD implantation or usual care. Outcomes were analysed according to NYHA class at baseline (NYHA class II and III/IV). The primary outcome was all-cause mortality. Of the 1116 patients randomized in the DANISH trial, 597 (53.5%) were in NYHA class II at baseline, 505 (45.3%) in NYHA class III, and 14 (1.3%) in NYHA class IV. During a median follow-up of 9.5 years, NYHA class III/IV, compared with NYHA class II, were associated with a greater long-term rate of all-cause mortality (hazard ratio [HR] 1.52, 95% confidence interval [CI] 1.20-1.93) and cardiovascular death (HR 1.95 [1.47-2.60]). ICD implantation, compared with usual care, did not reduce the long-term rate of all-cause mortality (all participants: HR 0.89 [95% CI 0.74-1.08]; NYHA class II: HR 0.85 [0.64-1.13]; NYHA class III/IV: HR 0.89 [0.69-1.14]; pinteraction = 0.78) or cardiovascular death (all participants: HR 0.87 [95% CI 0.70-1.09]; NYHA class II: HR 0.78 [0.54-1.12]; NYHA class III/IV: HR 0.89 [0.67-1.19]; pinteraction = 0.58), irrespective of NYHA class. Similarly, NYHA class did not modify the beneficial effects of ICD implantation on sudden cardiovascular death (all participants: HR 0.60 [95% CI 0.40-0.92]; NYHA class II: HR 0.73 [0.40-1.36]; NYHA class III/IV: HR 0.52 [0.29-0.94]; pinteraction = 0.39). CONCLUSIONS: In patients with non-ischaemic HFrEF, ICD implantation, compared with usual care, did not reduce the overall mortality rate, but it did reduce sudden cardiovascular death, regardless of baseline NYHA class.

Association between Preeclampsia and Long-term Risk of Arrhythmias.

BACKGROUND: Preeclampsia (PE), a pregnancy-induced hypertensive disorder, affects 4-5% of pregnancies worldwide. It is well known that hypertension is associated with an increased risk of arrhythmias; however, data on the association between PE and arrhythmias are sparse. METHODS: In this observational cohort study, we identified all primiparous women who gave birth in Denmark (1997-2016) using Danish nationwide registries. The women were stratified on whether they developed PE during primiparous pregnancy, and followed from primiparous pregnancy to incident arrhythmia, emigration, death, or end of study (December 31, 2018). RESULTS: A total of 523,271 primiparous women with a median age of 28 years were included and 23,367 (4.5%) were diagnosed with PE. During a median follow-up of 10.1 years, women with vs without PE were associated with a higher incidence of arrhythmias (1.42% vs 1.02%): 1) Composite of cardiac arrest, ventricular tachycardia/fibrillation, or ICD implantation (adjusted HR 1.60 [95% CI 1.14-2.24]), 2) Composite of advanced 2nd degree or 3rd degree atrioventricular block, sinoatrial dysfunction, or pacemaker implantation (adjusted HR 1.48 [95% CI 0.97-2.23]), 3) Composite of supraventricular tachyarrhythmias or extra systoles (adjusted HR 1.34 [95% CI 1.19-1.51]), 4) Composite of all the above-mentioned arrhythmias (adjusted HR 1.37 [95% CI 1.23-1.54]). CONCLUSION: Preeclamptic women were associated with a significantly and at hitherto unknown long-term increased rate of arrhythmias. This finding suggests that women with PE may benefit from cardiovascular risk assessment, screening, and preventive education.

This study examined whether preeclampsia, a condition that can occur during pregnancy and cause high blood-pressure, was linked to heart rhythm problems in first-time mothers. Women who had preeclampsia in their first pregnancy were more likely to develop heart rhythm problems later in life.This suggests that women with a history of preeclampsia might need extra attention to prevent future problems.

Cardiomyopathy in First-Degree Relatives of Patients Presenting With Acute Myocarditis: Prevalence and Prognostic Significance.

BACKGROUND: Acute myocarditis has been genetically linked to dilated cardiomyopathy (DCM), but the clinical significance remains uncertain. We investigated the prevalence and long-term prognosis of DCM and heart failure (HF) among unselected patients hospitalized with acute myocarditis and their first-degree relatives compared with an age- and sex-matched cohort. METHODS: This was an observational study utilizing the Danish nationwide registries, where all patients with a first-time myocarditis diagnosis from 1995 to 2018 were identified and matched (on birth year and sex) with 10 controls from the general population. RESULTS: Totally 3176 patients with acute myocarditis and 31 760 controls were included (median age, 49.8 [Q1-Q3, 32.5-70.2] years; 35.6% female). At baseline, patients with myocarditis had a higher prevalence of DCM (7 [0.2%] versus 8 [0.0%]) and HF (336 [10.6%] versus 695 [2.2%]) than controls; P<0.0001 for both. Patients with myocarditis more often had siblings with DCM (12 [0.4%] versus 17 [0.05%]) or HF (36 [1.1%] versus 89 [0.3%]); P<0.0001, odds ratios 7.09 (3.38-14.85) and 2.92 (1.25-6.80), respectively, whereas parental DCM and HF did not differ among patients with myocarditis and controls. Patients with myocarditis had greater 20-year incidence of DCM, HF, and all-cause mortality (0.5% [0.3%-0.9%], 15% [13%-17%], and 47% [44%-50%]) compared with controls (0.06% [0.03%-0.11%], 6.8% [6.4%-7.3%], and 34% [33%-35%]; P<0.0001). Having a first-degree relative with DCM or HF was associated with increased long-term mortality among the patients with myocarditis (hazard ratio, 1.40 [1.11-1.77]) but not among the controls (hazard ratio, 0.90 [0.81-1.01]; Pdifference=0.0008). CONCLUSIONS: Acute myocarditis aggregates with DCM within families, where it carries a worsened prognosis. A differential association between parents and siblings (with sibling preponderance) could suggest that additional environmental factors are important for myocarditis development even in predisposed individuals.

Glucagon-like-peptide-1 receptor agonists versus dipeptidyl peptidase-4 inhibitors and cardiovascular outcomes in diabetes in relation to achieved glycemic control. A Danish nationwide study.

AIM: To compare the cardiovascular preventive effect associated with glucagon-like-peptide-1 receptor agonists (GLP-1 RA) versus dipeptidyl peptidase-4 inhibitors (DPP-4i) according to the achieved target level of glycated hemoglobin (HbA1c). METHODS: We used retrospective Danish registries to include type 2 diabetes patients already in metformin treatment initiating GLP-1 RA or DPP-4i between 2007 and 2021. Patients were included 6 months after GLP-1 RA or DPP-4i initiation. The last available HbA1c measurement before inclusion was collected. The achieved HbA1c level was categorized according to a target level below or above 53 mmol/mol (7%). The primary outcome was a composite of nonfatal myocardial infarction, nonfatal stroke, and all-cause death. We used a multivariable Cox proportional hazard model to estimate the effect of HbA1c levels on the outcome among GLP-1 RA users compared to DPP-4i users. RESULTS: The study included 13 634 GLP-1 RA users (median age 56.9, interquartile range [IQR]: 48.5-65.5; 53% males) and 39 839 DPP-4i users (median age 63.4, IQR: 54.6-71.8; 61% males). The number of GLP-1 RA and DPP-4i users according to achieved HbA1c levels were as follows: HbA1c ≤ 53 mmol/mol (≤7.0%): 3026 (22%) versus 4824 (12%); HbA1c > 53 mmol/mol (>7.0%): 6577 (48%) versus 17 508 (44%); missing HbA1c: 4031 (30%) versus 17 507 (44%). During a median follow-up of 5 years (IQR: 2.6-5.0), 954 GLP-1 RA users experienced the primary outcome compared to 7093 DPP-4i users. The 5-year risk (95% confidence interval [CI]) of the outcome associated with GLP1-RA versus DPP-4i according to HbA1c categories was as follows: HbA1c ≤ 53 mmol/mol: 10.3% (8.2-12.3) versus 24.3% (22.7-25.8); HbA1c > 53 mmol/mol: 16.0% (14.3-17.6) versus 21.1% (20.3-21.9); missing HbA1c: 17.1% (15.7-18.5) versus 25.6% (24.9-26.3). The preventive effect associated with GLP-1 RA versus DPP-4i was significantly enhanced when achieving lower HbA1c levels: HbA1c ≤ 53 mmol/mol: 0.65 (0.52-0.80); HbA1c > 53 mmol/mol: 0.92 (0.83-1.03); missing HbA1c: 0.92 (0.84-1.02) (p value for interaction <.001). CONCLUSION: GLP-1 RA use was associated with a lower rate of major adverse cardiovascular outcomes. The association was stronger in patients achieving the target glycemic level and weaker in patients not achieving the target glycemic level, suggestive of an interaction between achieved HbA1c level and GLP-1 RA.

Effect of Implantable Cardioverter-defibrillators in Nonischemic Heart Failure According to Background Medical Therapy: Extended Follow-up of the DANISH Trial.

BACKGROUND: The Heart Failure Collaboratory (HFC) score integrates types and dosages of guideline-directed pharmacotherapies for heart failure (HF) with reduced ejection fraction (HFrEF). We examined the effects of cardioverter-defibrillator (ICD) implantation according to the modified HFC (mHFC) score in 1116 patients with nonischemic HFrEF from the Danish Study to Assess the Efficacy of ICDs in Patients with Nonischemic Systolic HF on Mortality (DANISH). METHODS AND RESULTS: Patients were assigned scores for renin-angiotensin-system inhibitors, beta-blockers and mineralocorticoid receptor antagonists (0, no use; 1, < 50% of maximum dosage; 2, ≥ 50% of maximum dosage). The maximum score was 6, corresponding to ≥ 50% of maximum dosage for all therapies. The median baseline mHFC score was 4, and the median follow-up was 9.5 years. Compared with an mHFC score of 3-4, an mHFC score of 1-2 was associated with a higher rate of all-cause death (mHFC = 1-2: adjusted HR 1.67 [95% CI, 1.23-2.28]; mHFC = 3-4, reference; mHFC = 5-6: adjusted HR 1.07 [95% CI, 0.87-1.31]). ICD implantation did not reduce all-cause death compared with control (reference) (HR 0.89 [95% CI, 0.74-1.08]), regardless of mHFC score (mHFC = 1-2: HR 0.98 [95% CI, 0.56-1.71]; mHFC = 3-4: HR 0.89 [95% CI,0.66-1.20]; mHFC = 5-6: HR 0.85 [95% CI, 0.64-1.12]; Pinteraction, 0.65). Similarly, ICD implantation did not reduce cardiovascular death (HR 0.87 [95% CI, 0.70-1.09]), regardless of mHFC score (Pinteraction, 0.59). The ICD group had a lower rate of sudden cardiovascular death (HR, 0.60 [95% CI,0.40-0.92]); this association was not modified by mHFC score (Pinteraction, 0.35). CONCLUSIONS: Lower mHFC scores were associated with higher rates of all-cause death. ICD implantation did not result in an overall survival benefit in patients with nonischemic HFrEF, regardless of mHFC score.

Association Between Vegetation Size and Outcome in the Partial Oral Antibiotic Endocarditis Treatment Trial.

Step-down oral antibiotic therapy is associated with a non-inferior long-term outcome compared with continued intravenous antibiotic therapy in the treatment of left-sided infective endocarditis. We aimed to analyze whether step-down oral therapy compared with continued intravenous antibiotic therapy is also associated with a non-inferior outcome in patients with large vegetations (vegetation length ≥ 10 mm) or among patients who underwent surgery before step-down oral therapy. We included patients without presence of aortic root abscess at diagnosis from the POET (Partial Oral Antibiotic Endocarditis Treatment) study. Multivariable Cox regression analyses were used to find associations between large vegetation, cardiac surgery, step-down oral therapy, and the primary end point (composite of all-cause mortality, unplanned cardiac surgery, embolic event, or relapse of positive blood cultures during follow-up). A total of 368 patients (age 68 ± 12, 77% men) were included. Patients with large vegetations (n = 124) were more likely to undergo surgery compared with patients with small vegetations (n = 244) (65% vs 20%, p <0.001). During a median 1,406 days of follow-up, 146 patients reached the primary end point. Large vegetations were not associated with the primary end point (hazard ratio 0.74, 95% confidence interval 0.47 to 1.18, p = 0.21). Step-down oral therapy was non-inferior to continued intravenous antibiotic in all subgroups when stratified by the presence of a large vegetation at baseline and early cardiac surgery. Step-down oral therapy is safe in the presence of a large vegetation at diagnosis and among patients who underwent early cardiac surgery.

Age-specific mortality trends in heart failure over 25 years: a retrospective Danish nationwide cohort study.

BACKGROUND: Despite advances in heart failure care reducing mortality in clinical trials, it remains unclear whether real-life cohorts have had similar improvements in life expectancy across the age spectrum. We aimed to investigate how mortality trends changed in patients with heart failure over the past 25 years, stratified by age groups. METHODS: Using Danish nationwide registries, we identified patients with new-onset heart failure aged 18-95 years. The 5-year all-cause mortality risk and the absolute risk difference of mortality between patients with heart failure and age-matched and sex-matched heart failure-free controls were assessed using Kaplan-Meier estimates and multivariable Cox regression models. Mortality trends were analysed across five calendar periods (1996-2000, 2001-05, 2006-10, 2011-15, and 2016-20) and three age groups (<65 years, 65-79 years, and ≥80 years). FINDINGS: 194 997 patients with heart failure were included. Mortality significantly decreased from 1996-2000 (66% [95% CI 65·5-66·4]) to 2016-20 (43% [42·1-43·4]), with similar results shown in all age groups (<65 years: 35% [33·9-36·1] to 15% [14·6-16·3]; 65-79 years: 64% [63·1-64·5] to 39% [37·6-39·6]; and ≥80 years: 84% [83·1-84·3] to 73% [71·7-73·9]). Adjusted mortality rates supported these associations. The absolute risk difference declined notably in younger age groups (<65 years: 29·9% [28·8-31·0] to 12·7% [12·0-13·4] and 65-79 years: 41·1% [40·3-41·9] to 25·1% [24·4-25·8]), remaining relatively stable in those aged 80 years or older (30·6% [29·9-31·3] to 28% [27·2-28·8]). INTERPRETATION: Over 25 years, there has been a consistent decrease in mortality among patients with heart failure across age groups, albeit less prominently in patients aged 80 years or older. Further insight is needed to identify effective strategies for improving disease burden in older patients with heart failure. FUNDING: None.

Dapagliflozin and quality of life measured using the EuroQol 5-dimension questionnaire in patients with heart failure with reduced and mildly reduced/preserved ejection fraction.

AIMS: Although much is known about the usefulness of heart failure (HF)-specific instruments for assessing patient well-being, less is known about the value of generic instruments for the measurement of health-related quality of life (HRQL) in HF. The aim of this study was to assess the relationship between the EuroQol 5-dimension 5-level (EQ-5D-5L) visual analogue scale (VAS) and index scores, clinical characteristics, and outcomes in patients with HF and the effect of dapagliflozin on these scores. METHODS AND RESULTS: We performed a patient-level pooled analysis of the DAPA-HF and DELIVER trials, which investigated the effectiveness and safety of dapagliflozin in patients with HF and reduced ejection fraction (HFrEF) and mildly reduced/preserved ejection fraction (HFmrEF/HFpEF), respectively. Patients reporting higher (better) EQ-5D-5L VAS and index scores had a lower prevalence of comorbidities, including atrial fibrillation and hypertension, than patients with a worse score. They were also more likely to have better investigator-reported (New York Heart Association class) and patient-self-reported (Kansas City Cardiomyopathy Questionnaire) health status and lower median N-terminal pro-B-type natriuretic peptide levels. Compared to patients with the lowest scores (Q1), those with higher EQ-5D-5L VAS scores had better outcomes: the hazard ratio for the composite of cardiovascular death or worsening HF was 0.81 (95% confidence interval 0.72-0.91) in Q2, 0.74 (0.65-0.84) in Q3, and 0.62 (0.54-0.72) in Q4. The risk of each component of the composite outcome, and all-cause death, was also lower in patients with better scores. Similar findings were observed for the index score. Treatment with dapagliflozin improved both EQ-5D-5L VAS and index scores across the range of ejection fraction. CONCLUSIONS: Both higher (better) EQ-5D-5L VAS and index scores were associated with better outcomes. Dapagliflozin treatment improved EQ-5D-5L VAS and index scores, irrespective of ejection fraction.

Use of medical therapy and risk of clinical events according to frailty in heart failure patients - A real-life cohort study.

AIMS: Although recent randomized clinical trials have demonstrated the advantages of heart failure (HF) therapy in both frail and not frail patients, there is insufficient information on the use of HF therapy based on frailty status in a real-world setting. The aim was to examine how frailty status in HF patients associates with use of HF therapy and with clinical outcomes. METHODS AND RESULTS: Patients with new-onset HF between 2014 and 2021 were identified using the nationwide Danish registers. Patients across the entire range of ejection fraction were included. The associations between frailty status (using the Hospital Frailty Risk Score) and use of HF therapy and clinical outcomes (all-cause mortality, HF hospitalization, and non-HF hospitalization) were evaluated using multivariable-adjusted Cox models adjusting for age, sex, diagnostic setting, calendar year, comorbidities, pharmacotherapy, and socioeconomic status. Of 35 999 participants (mean age 69.1 years), 68% were not frail, 26% were moderately frail, and 6% were severely frail. The use of HF therapy was significantly lower in frailer patients. The hazard ratio (HR) for angiotensin-converting enzyme inhibitor/angiotensin receptor blocker initiation was 0.74 (95% confidence interval 0.70-0.77) and 0.48 (0.43-0.53) for moderate frailty and severe frailty, respectively. For beta-blockers, the corresponding HRs were 0.74 (0.71-0.78) and 0.51 (0.46-0.56), respectively, and for mineralocorticoid receptor antagonists, 0.83 (0.80-0.87) and 0.58 (0.53-0.64), respectively. The prevalence of death and non-HF hospitalization increased with frailty status. The HR for death was 1.55 (1.47-1.63) and 2.32 (2.16-2.49) for moderate and severe frailty, respectively, and the HR for non-HF hospitalization was 1.37 (1.32-1.41) and 1.82 (1.72-1.92), respectively. The association between frailty status and HF hospitalization was not significant (HR 1.08 [1.02-1.14] and 1.08 [0.97-1.20], respectively). CONCLUSION: In real-world HF patients, frailty was associated with lower HF therapy use and with a higher incidence of clinical outcomes including mortality and non-HF hospitalization.
