The causal roadmap is a formal framework for causal and statistical inference that supports clear specification of the causal question, interpretable and transparent statement of required causal assumptions, robust inference, and optimal precision. The roadmap is thus particularly well-suited to evaluating longitudinal causal effects using large scale registries; however, application of the roadmap to registry data also introduces particular challenges. In this paper we provide a detailed case study of the longitudinal causal roadmap applied to the Danish National Registry to evaluate the comparative effectiveness of second-line diabetes drugs on dementia risk. Specifically, we evaluate the difference in counterfactual five-year cumulative risk of dementia if a target population of adults with type 2 diabetes had initiated and remained on GLP-1 receptor agonists (a second-line diabetes drug) compared to a range of active comparator protocols. Time-dependent confounding is accounted for through use of the iterated conditional expectation representation of the longitudinal g-formula as a statistical estimand. Statistical estimation uses longitudinal targeted maximum likelihood, incorporating machine learning. We provide practical guidance on the implementation of the roadmap using registry data, and highlight how rare exposures and outcomes over long-term follow up can raise challenges for flexible and robust estimators, even in the context of the large sample sizes provided by the registry. We demonstrate how simulations can be used to help address these challenges by supporting careful estimator pre-specification. We find a protective effect of GLP-1RAs compared to some but not all other second-line treatments.

Background: Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA) are increasingly being prescribed in drug‐naive patients. We aimed to contrast add‐on therapy, adherence, and changes in biomarkers, 1 year after treatment initiation with GLP‐1 RA or metformin. Methods: Using Danish nationwide registers, we included incident GLP‐1 RA or metformin users from 2018 to 2021 with glycated hemoglobin (HbA1c) ≥ 42 mmol/mol. GLP‐1 RA initiators were matched to metformin initiators in a ratio of 1:1 to assess outcomes in prediabetes and diabetes. Main outcomes analyzed were 1‐year risk of add‐on glucose‐lowering medication and 1‐year risk of nonadherence. One‐year risks were estimated with multiple logistic regression and standardized. Multiple linear regression was used to estimate the average differences in biomarker changes. Results: In total, 1778 individuals initiating GLP‐1 RA and metformin were included. After standardizing for various factors, GLP‐1 RA compared with metformin was associated with reduced 1‐year risk of add‐on glucose‐lowering treatment in patients with prediabetes (1‐year risk ratio [RR]: 0.27, 95% confidence interval [CI]: 0.10–0.44) and diabetes (RR: 0.67, 95% CI: 0.37–0.98). GLP‐1 RA was associated with higher 1‐year risk of nonadherence among patients with prediabetes (RR: 1.60, 95% CI: 1.45–1.75), but no difference in patients with diabetes (RR: 0.88, 95% CI: 0.70–1.06). Compared to metformin, GLP‐1 RA was associated with greater HbA1c reduction (prediabetes: −2.59 mmol/mol 95% CI: −3.10 to −2.09, diabetes: −3.79 mmol/mol, 95% CI: −5.28 to −2.30). Conclusions: GLP‐1 RA was associated with a reduced risk of additional glucose‐lowering medication, achieving better glycated hemoglobin control overall. However, among patients with prediabetes, metformin was associated with better adherence. [ABSTRACT FROM AUTHOR]

- Abstract
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).

- Abstract
Background Prevention and management of childhood overweight involves the entire family. We aimed to investigate purchase patterns in households with at least one member with overweight in childhood by describing expenditure on different food groups. Methods This Danish register-based cohort study included households where at least one member donated receipts concerning consumers purchases in 2019–2021 and at least one member had their Body mass index (BMI) measured in childhood within ten years prior to first purchase. A probability index model was used to evaluate differences in proportion expenditure spent on specific food groups. Results We identified 737 households that included a member who had a BMI measurement in childhood, 220 with overweight and 517 with underweight or normal weight (reference households). Adjusting for education, income, family type, and urbanization, households with a member who had a BMI classified as overweight in childhood had statistically significant higher probability of spending a larger proportion of expenditure on ready meals 56.29% (95% CI: 51.70;60.78) and sugary drinks 55.98% (95% CI: 51.63;60.23). Conversely, they had a statistically significant lower probability of spending a larger proportion expenditure on vegetables 38.44% (95% CI: 34.09;42.99), compared to the reference households. Conclusion Households with a member with BMI classified as overweight in childhood spent more on unhealthy foods and less on vegetables, compared to the reference households. This study highlights the need for household/family-oriented nutrition education and intervention., BACKGROUND: Prevention and management of childhood overweight involves the entire family.

- Abstract
Aims/hypothesis: We aimed to examine whether individuals with initial omission of glucose-lowering drug treatment (GLDT), including those achieving initial remission of type 2 diabetes, may experience a higher risk of major adverse cardiovascular events (MACE) compared with well-controlled individuals on GLDT after a new type 2 diabetes diagnosis in real-world clinical practice. Furthermore, we examined whether a higher risk could be related to lower initiation of statins and renin–angiotensin system inhibitors (RASi). Methods: In this cohort study, we used Danish registers to identify individuals with a first measured HbA1c between 48 and 57 mmol/mol (6.5–7.4%) from 2014 to 2020. Six months later, we divided participants into four groups according to GLDT and achieved HbA1c (<48 vs ≥48 mmol/mol [6.5%]): well-controlled and poorly controlled on GLDT; remission and persistent type 2 diabetes not on GLDT. We reported how much the standardised 5 year risk of MACE could be reduced for each group if initiation of statins and RASi was the same as in the well-controlled group on GLDT. Results: We included 14,221 individuals. Compared with well-controlled participants on GLDT, the 5 year standardised risk of MACE was higher in the three other exposure groups: by 3.3% (95% CI 1.6, 5.1) in the persistent type 2 diabetes group not on GLDT; 2.0% (95% CI 0.4, 3.7) in the remission group not on GLDT; and 3.5% (95% CI 1.3, 5.7) in the poorly controlled group on GLDT. Fewer individuals not on GLDT initiated statins and RASi compared with individuals on GLDT. If initiation of statins and RASi had been the same as in the well-controlled group on GLDT, participants not on GLDT could have reduced their risk of MACE by 2.1% (95% CI 1.2, 2.9) in the persistent type 2 diabetes group and by 1.1% (95% CI 0.4, 1.9) in the remission group. Conclusions/interpretation: Compared with well-controlled individuals on GLDT, individuals not on initial GLDT had a higher 5 y

- Abstract
OBJECTIVE To compare the incidence of type 1 diabetes (T1D) before and during the coronavirus disease 2019 (COVID-19) pandemic and determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with T1D development. RESEARCH DESIGN AND METHODS All Danish residents aged <30 years free of diabetes from 2015 to 2021 were included. Individuals were followed from 1 January 2015 or birth until the development of T1D, the age of 30, the end of the study (31 December 2021), emigration, development of type 2 diabetes, onset of any cancer, initiation of immunomodulating therapy, or development of any autoimmune disease. We compared the incidence rate ratio (IRR) of T1D using Poisson regression models. We matched each person with a SARS-CoV-2 infection with three control individuals and used a cause-specific Cox regression model to estimate the hazard ratio (HR). RESULTS Among 2,381,348 individuals, 3,579 cases of T1D occurred. The adjusted IRRs for T1D in each quarter of 2020 and 2021 compared with 2015–2019 were as follows: January–March 2020, 1.03 (95% CI 0.86; 1.23); January–March 2021, 1.01 (0.84; 1.22), April–June 2020, 0.98 (0.80; 1.20); April–June 2021, 1.34 (1.12; 1.61); July–September 2020, 1.13 (0.94; 1.35); July–September 2021, 1.21 (1.01; 1.45); October–December 2020, 1.09 (0.91; 1.31); and October–December 2021, 1.18 (0.99; 1.41). We identified 338,670 individuals with a positive SARS-CoV-2 test result and matched them with 1,004,688 control individuals. A SARS-2-CoV infection was not significantly associated with the risk of T1D development (HR 0.90 [95% CI 0.60; 1.35]). CONCLUSIONS There was an increase in T1D incidence during April–June 2021 compared with April–June 2015–2019, but this could not be attributed to SARS-CoV-2 infection., OBJECTIVE To compare the incidence of type 1 diabetes (T1D) before and during the coronavirus disease 2019 (COVID-19) pandemic and determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with T1D development.

- Abstract
Aims We studied the effect of discontinuing beta-blockers following myocardial infarction in comparison to continuous beta-blocker use in optimally treated, stable patients without heart failure. Methods and results Using nationwide registers, we identified first-time myocardial infarction patients treated with beta-blockers following percutaneous coronary intervention or coronary angiography. The analysis was based on landmarks selected as 1, 2, 3, 4, and 5 years after the first redeemed beta-blocker prescription date. The outcomes included all-cause death, cardiovascular death, recurrent myocardial infarction, and a composite outcome of cardiovascular events and procedures. We used logistic regression and reported standardized absolute 5-year risks and risk differences at each landmark year. Among 21 220 first-time myocardial infarction patients, beta-blocker discontinuation was not associated with an increased risk of all-cause death, cardiovascular death, or recurrent myocardial infarction compared with patients continuing beta-blockers (landmark year 5; absolute risk difference [95% confidence interval]), correspondingly; −4.19% [−8.95%; 0.57%], −1.18% [−4.11%; 1.75%], and −0.37% [−4.56%; 3.82%]). Further, beta-blocker discontinuation within 2 years after myocardial infarction was associated with an increased risk of the composite outcome (landmark year 2; absolute risk [95% confidence interval] 19.87% [17.29%; 22.46%]) compared with continued beta-blocker use (landmark year 2; absolute risk [95% confidence interval] 17.10% [16.34%; 17.87%]), which yielded an absolute risk difference [95% confidence interval] at −2.8% [−5.4%; −0.1%], however, there was no risk difference associated with discontinuation hereafter. Conclusion Discontinuation of beta-blockers 1 year or later after a myocardial infarction without heart failure was not associated with increased serious adverse events, AIMS: We studied the effect of discontinuing beta-blockers following myocardial infarction in comparison to continuous beta-blocker use in optimally treated, stable patients without heart failure.METHODS AND RESULTS: Using nationwide registers, we identified first-time myocardial infarction patients treated with beta-blockers following percutaneous coronary intervention or coronary angiography. The analysis was based on landmarks selected as 1, 2, 3, 4, and 5 years after the first redeemed beta-blocker prescription date. The outcomes included all-cause death, cardiovascular death, recurrent myocardial infarction, and a composite outcome of cardiovascular events and procedures. We used logistic regression and reported standardized absolute 5-year risks and risk differences at each landmark year. Among 21 220 first-time myocardial infarction patients, beta-blocker discontinuation was not associated with an increased risk of all-cause death, cardiovascular death, or recurrent myocardial infarction compared with patients continuing beta-blockers (landmark year 5; absolute risk difference [95% confidence interval]), correspondingly; -4.19% [-8.95%; 0.57%], -1.18% [-4.11%; 1.75%], and -0.37% [-4.56%; 3.82%]). Further, beta-blocker discontinuation within two years after myocardial infarction was associated with an increased risk of the composite outcome (landmark year 2; absolute risk [95% confidence interval] 19.87% [17.29%; 22.46%]) compared with continued beta-blocker use (landmark year 2; absolute risk [95% confidence interval] 17.10% [16.34%; 17.87%]), which yielded an absolute risk difference [95% confidence interval] at -2.8% [-5.4%; -0.1%], however, there was no risk difference associated with discontinuation hereafter.CONCLUSION: Discontinuation of beta-blockers one year or later after a myocardial infarction without heart failure was not associated with increased serious adverse events.

OBJECTIVE: To compare the incidence of type 1 diabetes (T1D) before and during the coronavirus disease 2019 (COVID-19) pandemic and determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with T1D development. RESEARCH DESIGN AND METHODS: All Danish residents aged <30 years free of diabetes from 2015 to 2021 were included. Individuals were followed from 1 January 2015 or birth until the development of T1D, the age of 30, the end of the study (31 December 2021), emigration, development of type 2 diabetes, onset of any cancer, initiation of immunomodulating therapy, or development of any autoimmune disease. We compared the incidence rate ratio (IRR) of T1D using Poisson regression models. We matched each person with a SARS-CoV-2 infection with three control individuals and used a cause-specific Cox regression model to estimate the hazard ratio (HR). RESULTS: Among 2,381,348 individuals, 3,579 cases of T1D occurred. The adjusted IRRs for T1D in each quarter of 2020 and 2021 compared with 2015–2019 were as follows: January–March 2020, 1.03 (95% CI 0.86; 1.23); January–March 2021, 1.01 (0.84; 1.22), April–June 2020, 0.98 (0.80; 1.20); April–June 2021, 1.34 (1.12; 1.61); July–September 2020, 1.13 (0.94; 1.35); July–September 2021, 1.21 (1.01; 1.45); October–December 2020, 1.09 (0.91; 1.31); and October–December 2021, 1.18 (0.99; 1.41). We identified 338,670 individuals with a positive SARS-CoV-2 test result and matched them with 1,004,688 control individuals. A SARS-2-CoV infection was not significantly associated with the risk of T1D development (HR 0.90 [95% CI 0.60; 1.35]). CONCLUSIONS: There was an increase in T1D incidence during April–June 2021 compared with April–June 2015–2019, but this could not be attributed to SARS-CoV-2 infection. [ABSTRACT FROM AUTHOR]

- Abstract
Objective Gastrointestinal bleeding (GIB) risk in relation to concomitant treatment with non-vitamin K oral anticoagulants (NOAC) and oral glucocorticoids is insufficiently explored. We aimed to investigate the short-term risk following coexposure. Methods This is a register-based, nationwide Danish study including patients with atrial fibrillation on NOACs during 2012–2018. Patients were defined as exposed to oral glucocorticoids if they claimed a prescription within 60 days prior to GIB. We investigated the associations between GIB and oral glucocorticoid exposure, reporting HRs via a nested case–control design and absolute risk via a cohort design. Matching terms were age, sex, calendar year, follow-up time and NOAC agent. Results 98 376 patients on NOACs (median age: 75 years (IQR: 68–82), 44% female) were included, and 16% redeemed at least one oral glucocorticoid prescription within 3 years. HRs of GIB were increased comparing exposed with non-exposed patients (<20 mg daily dose, HR 1.54 (95% CI 1.29 to 1.84); ≥20 mg daily dose, HR 2.19 (95% CI 1.81 to 2.65)). 60-day standardised absolute risk of GIB following first claimed oral glucocorticoid prescription increased compared with non-exposed: 60-day absolute risk: 0.71% (95% CI 0.58% to 0.85%) vs 0.38% (95% CI 0.32% to 0.43%). The relative risk was elevated as well: risk ratio of 1.89 (95% CI 1.43 to 2.36). Conclusions Concomitant treatment with NOACs and oral glucocorticoids was associated with a short-term rate and risk increase of GIB compared with patients only on NOACs. This could have implications for clinical management, necessitating closer monitoring or other risk mitigation strategies during episodes of cotreatment with oral glucocorticoids.

- Abstract
AIMS : The association between socioeconomic position and cardiovascular disease has not been well studied in patients with type 2 diabetes. We aimed to examine the association between socioeconomic position and first-time major adverse cardiovascular events (MACE) in patients with type 2 diabetes.METHODS AND RESULTS : Through the Danish nationwide registers, we identified all residents with newly diagnosed type 2 diabetes between 2012 and 2017. Based on sex-stratified multivariable cause-specific Cox regression models, we calculated the standardized absolute 5-year risk of the composite outcome of first-time myocardial infarction, stroke, or cardiovascular mortality (MACE) according to income quartiles. A total of 57 106 patients with type 2 diabetes were included. During 155 989 person years, first-time MACE occurred in 2139 patients. Among both men and women, income was inversely associated with the standardized absolute 5-year risk of MACE. In men, the 5-year risk of MACE increased from 5.7% [95% confidence interval (CI) 4.9-6.5] in the highest income quartile to 9.3% (CI 8.3-10.2) in the lowest income group, with a risk difference of 3.5% (CI 2.4-4.7). In women, the risk of MACE increased from 4.2% (CI 3.4-5.0) to 6.1% (CI 5.2-7.0) according to income level, with a risk difference of 1.9% (CI 0.8-2.9).CONCLUSION : Despite free access to medical care in Denmark, low-socioeconomic position was associated with a higher 5-year risk of first-time MACE in patients with incident type 2 diabetes. Our results suggest prevention strategies could be developed specifically for patients with low-socioeconomic position.

- Abstract
AIMS: We aimed to investigate the long-term cardio-protective effect associated with beta-blocker (BB) treatment in stable, optimally treated myocardial infarction (MI) patients without heart failure (HF).METHODS AND RESULTS: Using nationwide registries, we included patients with first-time MI undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI) during admission and treated with both acetyl-salicylic acid and statins post-discharge between 2003 and 2018. Patients with prior history of MI, prior BB use, or any alternative indication or contraindication for BB treatment were excluded. Follow-up began 3 months following discharge in patients alive, free of cardiovascular (CV) events or procedures. Primary outcomes were CV death, recurrent MI, and a composite outcome of CV events. We used adjusted logistic regression and reported standardized absolute risks and differences (ARD) 3 years after MI. Overall, 30 177 stable, optimally treated MI patients were included (58% acute PCI, 26% sub-acute PCI, 16% CAG without intervention). At baseline, 82% of patients were on BB treatment (median age 61 years, 75% male) and 18% were not (median age 62 years, 68% male). BB treatment was associated with a similar risk of CV death, recurrent MI, and the composite outcome of CV events compared with no BB treatment [ARD (95% confidence intervals)] correspondingly; 0.1% (-0.3% to 0.5%), 0.2% (-0.7% to 1.2%), and 1.2% (-0.2% to 2.7%).CONCLUSIONS: In this nationwide cohort study of stable, optimally treated MI patients without HF, we found no long-term effect of BB treatment on CV prognosis following the patients from 3 months to 3 years after MI admission.

- Abstract
Aim To determine the incidence, patient characteristics, and related events associated with new-onset atrial fibrillation (AF) during a national COVID-19 lockdown. Methods Using nationwide Danish registries, we included all patients, aged 18-90 years, receiving a new-onset AF diagnosis and results during the first 3 months of 2019 and 2020. The main comparison was between patients diagnosed during lockdown (12 March 12-1 April 2020) and patients diagnosed in the corresponding period 1 year previously. We found a lower incidence of new-onset AF during the 3 weeks of lockdown compared with the corresponding weeks in 2019 [incidence rate ratios with 95% confidence intervals (CIs) for the 3 weeks: 0.66 (0.56-0.78), 0.53 (0.45-0.64), and 0.41 (0.34-0.50)]. There was a 47% drop in total numbers (562 vs. 1053). Patients diagnosed during lockdown were younger and with a lower CHA2DS2-VASc score, while history of cancer, heart failure, and vascular disease were more prevalent. During lockdown, 30 (5.3%) patients with new-onset AF suffered an ischaemic stroke and 15 (2.7%) died, compared with 45 (4.3%) and 14 (1.3%) patients during the corresponding 2019 period, respectively. The adjusted odds ratio of a related event (ischaemic stroke or all-cause death) during lock-down compared with the corresponding weeks was 1.41 (95% CI 0.93-2.12). Conclusions Following a national lockdown in Denmark, a 47% drop in registered new-onset AF cases was observed. In the event of prolonged or subsequent lockdowns, the risk of undiagnosed AF patients developing complications could potentially translate into poorer outcomes in patients with AF during the COVID-19 pandemic.

- Abstract
BACKGROUND: Heart failure (HF) in patients with type 2 diabetes mellitus (T2D) has received growing attention. We examined the effect of HF development on prognosis compared with other cardiovascular or renal diagnoses in patients with T2D. METHODS AND RESULTS: Patients with new T2D diagnosis patients were identified between 1998 and 2015 through Danish nationwide registers. At yearly landmark timepoints after T2D diagnosis, we estimated the 5-year risks of death, 5-year risk ratios, and decrease in lifespan within 5 years associated with the development of HF, ischemic heart disease, stroke, peripheral artery disease, and chronic kidney disease. A total of 153 403 patients with newly diagnosed T2D were followed for a median of 9.7 years (interquartile range, 5.8-13.9) during which 48 087 patients died. The 5-year risk ratio of death associated with HF development 5 years after T2D diagnosis was 3 times higher (CI, 2.9-3.1) than patients free of diagnoses (CI, 2.9-3.1). Five-year risk ratios were lower for ischemic heart disease (1.3 [1.3-1.4]), stroke (2.2 [2.1-2.2]), chronic kidney disease (1.7 [1.7-1.8]), and peripheral artery disease (2.3 [2.3-2.4]). The corresponding decrease in lifespan within 5 years when compared with patients free of diagnoses (in months) was HF 11.7 (11.6-11.8), ischemic heart disease 1.6 (1.5-1.7), stroke 6.4 (6.3-6.5), chronic kidney disease 4.4 (4.3-4.6), and peripheral artery disease 6.9 (6.8-7.0). HF in combination with any other diagnosis imposed the greatest risk of death and decrease in life span compared with other combinations. Supplemental analysis led to similar results when stratified according to age, sex, and comorbidity status, and inclusion period. CONCLUSIONS: HF development, at any year since T2D diagnosis, was associated with the highest 5-year absolute and relative risk of death, and decrease in lifespan within 5 years, when compared with development of other cardiovascular or renal diagnoses.

classification ,EEG ,Coma ,Bayesian - Abstract
A patient who does not regain full consciousness after coma is typically classified as being in a vegetative state or a minimally conscious state. While the key determinants in this differential diagnosis are inferred uniquely from the observed behaviour of the patient, nothing can, in principle, be known about the patient’s awareness of the external world. Given the subjective nature of current diagnostic practice, the quest for neurophysiological markers that could complement the nosology of the coma spectrum is becoming more and more acute. We here present a method for the classification of patients based on electrophysiological responses using Bayesian model selection. We validate the method in a sample of fourteen patients with a clinical disorder of consciousness (DoC) and a control group of fifteen healthy adults. By formally comparing a set of alternative hypotheses about the nosology of DoC patients, the results of our validation study show that we can disambiguate between alternative models of how patients are classified. Although limited to this small sample of patients, this allowed us to assert that there is no evidence of subgroups when looking at the MMN response in this sample of patients. We believe that the methods presented in this article are an important contribution to testing alternative hypotheses about how patients are grouped at both the group and single-patient level and propose that electrophysiological responses, recorded invasively or non-invasively, may be informative for the nosology of the coma spectrum on a par with behavioural diagnosis.

- Abstract
BACKGROUND: Whether there is an association between sleep apnea (SA) and the risk of developing heart failure (HF) is unclear. Furthermore, it has never been established whether continuous positive airway pressure (CPAP) therapy can prevent development of HF. We aimed to investigate SA patients' risk of developing HF and the association of CPAP therapy.METHODS AND RESULTS: Using nationwide databases, the entire Danish population was followed from 2000 until 2012. patients with SA receiving and not receiving CPAP therapy were identified and compared with the background population. The primary end point was first-time hospital contact for HF and adjusted incidence rate ratios of HF were calculated using Poisson regression models. Among 4.9 million individuals included, 40 485 developed SA during the study period (median age: 53.4 years, 78.5% men) of whom 45.2% received CPAP therapy. Crude rates of HF were increased in all patients with SA relative to the background population. In the adjusted model, the incidence rate ratios of HF were increased in the untreated SA patients of all ages, compared with the background population. Comparing the CPAP-treated patients with SA with the untreated patients with SA showed significantly lower incidence rate ratios of HF among older patients.CONCLUSIONS: In this nationwide cohort study, SA not treated with CPAP was associated with an increased risk of HF in patients of all ages. Use of CPAP therapy was associated with a lower risk of incident HF in patients >60 years of age, suggesting a protective effect of CPAP therapy in the elderly.

- Abstract
Aims: To assess the association between statin use and cataract surgery according to different statin treatment durations in patients with different cardiovascular risk profiles., Methods and Results: We performed a nested case-control study using Danish registries, covering the period from 1 January 1996 to 31 December 2020. We defined cases as surgically treated cataract patients, matched in a 1:1 ratio by sex and age with controls not undergoing cataract surgery. The exposure of interest was statin use in different durations (1, 5 and 10 years) compared with never use of statins. Conditional logistic regression provided adjusted HRs and corresponding 95% CIs in subgroups defined by established atherosclerotic cardiovascular disease, diabetes, hypertension and individuals without these comorbidities. We identified 505 150 cataract surgery cases and found no increased HR of cataract surgery with statin treatment at any duration in any of the subgroups with established atherosclerotic cardiovascular disease, diabetes or hypertension., Conclusion: Our findings do not support a possible association between long-term statin use and cataract in patients with established atherosclerotic cardiovascular disease, diabetes or hypertension. Although we found an association between statin use and cataract in individuals without these comorbidities, increasing durations of statin use did not yield higher cataract surgery rates., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
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., (© 2024 The Authors.

- Abstract
Aims: We studied the effect of discontinuing beta-blockers following myocardial infarction in comparison to continuous beta-blocker use in optimally treated, stable patients without heart failure., Methods and Results: Using nationwide registers, we identified first-time myocardial infarction patients treated with beta-blockers following percutaneous coronary intervention or coronary angiography. The analysis was based on landmarks selected as 1, 2, 3, 4, and 5 years after the first redeemed beta-blocker prescription date. The outcomes included all-cause death, cardiovascular death, recurrent myocardial infarction, and a composite outcome of cardiovascular events and procedures. We used logistic regression and reported standardized absolute 5-year risks and risk differences at each landmark year. Among 21 220 first-time myocardial infarction patients, beta-blocker discontinuation was not associated with an increased risk of all-cause death, cardiovascular death, or recurrent myocardial infarction compared with patients continuing beta-blockers (landmark year 5; absolute risk difference [95% confidence interval]), correspondingly; -4.19% [-8.95%; 0.57%], -1.18% [-4.11%; 1.75%], and -0.37% [-4.56%; 3.82%]). Further, beta-blocker discontinuation within 2 years after myocardial infarction was associated with an increased risk of the composite outcome (landmark year 2; absolute risk [95% confidence interval] 19.87% [17.29%; 22.46%]) compared with continued beta-blocker use (landmark year 2; absolute risk [95% confidence interval] 17.10% [16.34%; 17.87%]), which yielded an absolute risk difference [95% confidence interval] at -2.8% [-5.4%; -0.1%], however, there was no risk difference associated with discontinuation hereafter., Conclusion: Discontinuation of beta-blockers 1 year or later after a myocardial infarction without heart failure was not associated with increased serious adverse events., (© The Author(s) 2023.

- Abstract
Objective: Gastrointestinal bleeding (GIB) risk in relation to concomitant treatment with non-vitamin K oral anticoagulants (NOAC) and oral glucocorticoids is insufficiently explored. We aimed to investigate the short-term risk following coexposure., Methods: This is a register-based, nationwide Danish study including patients with atrial fibrillation on NOACs during 2012-2018. Patients were defined as exposed to oral glucocorticoids if they claimed a prescription within 60 days prior to GIB. We investigated the associations between GIB and oral glucocorticoid exposure, reporting HRs via a nested case-control design and absolute risk via a cohort design. Matching terms were age, sex, calendar year, follow-up time and NOAC agent., Results: 98 376 patients on NOACs (median age: 75 years (IQR: 68-82), 44% female) were included, and 16% redeemed at least one oral glucocorticoid prescription within 3 years. HRs of GIB were increased comparing exposed with non-exposed patients (<20 mg daily dose, HR 1.54 (95% CI 1.29 to 1.84); ≥20 mg daily dose, HR 2.19 (95% CI 1.81 to 2.65)). 60-day standardised absolute risk of GIB following first claimed oral glucocorticoid prescription increased compared with non-exposed: 60-day absolute risk: 0.71% (95% CI 0.58% to 0.85%) vs 0.38% (95% CI 0.32% to 0.43%). The relative risk was elevated as well: risk ratio of 1.89 (95% CI 1.43 to 2.36)., Conclusions: Concomitant treatment with NOACs and oral glucocorticoids was associated with a short-term rate and risk increase of GIB compared with patients only on NOACs. This could have implications for clinical management, necessitating closer monitoring or other risk mitigation strategies during episodes of cotreatment with oral glucocorticoids., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

- Abstract
Aims: The association between socioeconomic position and cardiovascular disease has not been well studied in patients with type 2 diabetes. We aimed to examine the association between socioeconomic position and first-time major adverse cardiovascular events (MACE) in patients with type 2 diabetes., Methods and Results: Through the Danish nationwide registers, we identified all residents with newly diagnosed type 2 diabetes between 2012 and 2017. Based on sex-stratified multivariable cause-specific Cox regression models, we calculated the standardized absolute 5-year risk of the composite outcome of first-time myocardial infarction, stroke, or cardiovascular mortality (MACE) according to income quartiles. A total of 57 106 patients with type 2 diabetes were included. During 155 989 person years, first-time MACE occurred in 2139 patients. Among both men and women, income was inversely associated with the standardized absolute 5-year risk of MACE. In men, the 5-year risk of MACE increased from 5.7% [95% confidence interval (CI) 4.9-6.5] in the highest income quartile to 9.3% (CI 8.3-10.2) in the lowest income group, with a risk difference of 3.5% (CI 2.4-4.7). In women, the risk of MACE increased from 4.2% (CI 3.4-5.0) to 6.1% (CI 5.2-7.0) according to income level, with a risk difference of 1.9% (CI 0.8-2.9)., Conclusion: Despite free access to medical care in Denmark, low-socioeconomic position was associated with a higher 5-year risk of first-time MACE in patients with incident type 2 diabetes. Our results suggest prevention strategies could be developed specifically for patients with low-socioeconomic position., (© The Author(s) 2021.
