Background Small observational studies have observed poor persistency to sodium-glucose cotransporter-2 inhibitors (SGLT2-i) and glucacon-like-peptide-1-receptor agonists (GLP1-RA), contrary to what has been reported in clinical trials. Therefore, we investigated the risk of discontinuing SGLT2-is and GLP1-RAs in patients with type 2 diabetes (T2D) in a nationwide population. Methods From Danish nationwide registers, all first-time users of SGLT2-is and GLP1-RAs from 2013 to 2021 were identified. Adherence over the first year of therapy, the five-year risk of discontinuing therapy for the first time and the subsequent one-year probability of reinitiating therapy, was assessed. The Aalen-Johansen estimator was used to account for censoring and competing risks and multivariable Cox regression models were used to identify covariates associated with discontinuation. Findings A total of 77,745 first-time users of SGLT2-is (64% male, median age 64 [interquartile range 56–72]) and 56,037 first-time users of GLP1-RAs (56% male, median age 61 [53–70]) were included. The absolute five-year risk of discontinuing therapy was 56% (95% CI: 55–57) and 45% (45–46) for SGLT2-i- and GLP1-RA users, respectively, with a significantly decreased risk over the period studied. The subsequent one-year probability of reinitiating therapy was 24% (95% CI: 24–25) for initial SGLT2-i users and 26% (25–27) for GLP1-RA users. Interpretation Approximately half of the users of SGLT2-is and GLP1-RAs discontinued therapy within five years, respectively. However, a large proportion of these patients reinitiated therapy during the following year. Further insight into the reasons for discontinuation and initiatives to reduce the time to reinitiation in eligible patients are warranted.

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 Employment is important for physical and mental health and self-esteem and provides financial independence. However, little is known on the prognostic value of employment status prior to admission with acute myocardial infarction (MI). Methods and results Using Danish nationwide registries, all patients between 18 and 60 years with a first-time MI admission (2010–2018) and alive at discharge were included. Rates of all-cause mortality and recurrent MI according to workforce attachment at the time of the event was compared using multivariable Cox regression. Of the 16 060 patients included in the study, 3520 (21.9%) patients were not part of the workforce. Patients who were not part of the workforce were older (52 vs. 51 years), less often men (63% vs. 77%), less likely to have higher education, more often living alone (47% vs. 29%), and more often had comorbidities, including heart failure, atrial fibrillation, hypertension, diabetes, chronic kidney disease, and chronic obstructive pulmonary disease. The absolute 5-year risk of death was 3.3% and 12.8% in the workforce and non-workforce group, respectively. The corresponding rates of recurrent MI were 7.5% and 10.9%, respectively. In adjusted analyses, not being part of the workforce was associated with a significantly higher rate of all-cause mortality [HR: 2.39 (95% CI: 2.01–2.83)] and recurrent MI [1.36 (1.18–1.57)]. Conclusion Among patients of working age who were admitted with MI and alive at discharge, not being part of the workforce was associated with a higher long-term rate of all-cause mortality and recurrent MI, Background Employment is important for physical and mental health and self-esteem and provides financial independence.

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

Aim To determine the risk of adverse outcomes across the spectrum of glycated haemoglobin (HbA1c) levels among hospitalized COVID-19 patients with and without diabetes. Materials and methods Danish nationwide registries were used to study the association between HbA1c levels and 30-day risk of all-cause mortality and the composite of severe COVID-19 infection, intensive care unit (ICU) admission and all-cause mortality. The study population comprised patients hospitalized with COVID-19 (3 March 2020 to 31 December 2020) with a positive polymerase chain reaction (PCR) test and an available HbA1c ≤ 6 months before the first positive PCR test. All patients had at least 30 days of follow-up. Among patients with diabetes, HbA1c was categorized as <48 mmol/mol, 48 to 53 mmol/mol, 54 to 58 mmol/mol, 59 to 64 mmol/mol (reference) and >64 mmol/mol. Among patients without diabetes, HbA1c was stratified into <31 mmol/mol, 31 to 36 mmol/mol (reference), 37 to 41 mmol/mol and 42 to 47 mmol/mol. Thirty-day standardized absolute risks and standardized absolute risk differences are reported. Results We identified 3295 hospitalized COVID-19 patients with an available HbA1c (56.2% male, median age 73.9 years), of whom 35.8% had diabetes. The median HbA1c was 54 and 37 mmol/mol among patients with and without diabetes, respectively. Among patients with diabetes, the standardized absolute risk difference of the composite outcome was higher with HbA1c < 48 mmol/mol (12.0% [95% confidence interval {CI} 3.3% to 20.8%]) and HbA1c > 64 mmol/mol (15.1% [95% CI 6.2% to 24.0%]), compared with HbA1c 59 to 64 mmol/mol (reference). Among patients without diabetes, the standardized absolute risk difference of the composite outcome was greater with HbA1c < 31 mmol/mol (8.5% [95% CI 0.5% to 16.5%]) and HbA1c 42 to 47 mmol/mol (6.7% [95% CI 1.3% to 12.1%]), compared with HbA1c 31 to 36 mmol/mol (reference). Conclusions Patients with COVID-1

Background and Purpose: It is well-established that increasing treatment delay reduces the benefits of thrombolysis in patients with acute ischemic stroke. However, most studies focus on short-term outcomes. This study examined long-term outcomes according to time to thrombolysis in patients with first-time ischemic stroke. Methods: In this nationwide cohort study, all Danish patients with first-time ischemic stroke treated with intravenous thrombolysis between 2011 and 2017 and alive at discharge were identified through the Danish Stroke Registry. The association between time from symptom onset to thrombolysis and the long-term rate of the composite of death and recurrent ischemic stroke was examined using multivariable Cox regression and restricted cubic spline analysis. Results: The study population included 6252 patients with first-time ischemic stroke treated with thrombolysis (median age, 69 years [25th-75th percentile 60-78 years], 60% men). The median follow-up was 2.5 years (25th-75th percentile 1.2-4.1 years). The median time to thrombolysis was 138 minutes (25th-75th percentile 101-185 minutes), and the median National Institutes of Health Stroke Scale score at presentation was 5 (25th-75th percentile 3-10). The absolute 3-year risk of the composite outcome was 19.0% (95% CI, 16.4%-21.8%) in the 0 to 90 minute group, 23.3% (21.8%-24.9%) in the 91 to 180 minute group, and 23.8% (21.6%-26.1%) in the 181 to 270 minute group. Compared with thrombolysis within 90 minutes, time to thrombolysis >90 minutes was associated with a higher rate of the composite outcome (91-180 minute: Adjusted hazard ratio, 1.25 [95% CI, 1.06-1.48]; 181-270 minutes: Adjusted hazard ratio, 1.35 [95% CI, 1.12-1.61]). In restricted cubic spline analysis, the rate of the composite outcome increased with increasing time to thrombolysis and leveled off after 138 minutes. Conclusions: In this nationwide cohort of patients with ischemic stroke, the long-term rate of the composite of de
