RESUMEN
BACKGROUND: Leaflet calcification contributes to the development and progression of aortic valve stenosis. Vitamin K activates inhibitors of vascular calcification and may modulate inflammation and skeletal bone loss. Therefore, we aimed to determine whether higher dietary intakes of vitamin K1 are associated with a lower incidence of aortic stenosis. METHODS: In the Danish Diet, Cancer and Health study, participants aged 50 to 64 years completed a 192-item food frequency questionnaire at baseline, from which habitual intakes of vitamin K1 were estimated. Participants were prospectively followed using linkage to nationwide registers to determine incident aortic valve stenosis (primary outcome) and aortic stenosis with subsequent complications (aortic valve replacement, heart failure, or cardiovascular disease-related mortality; secondary outcome). RESULTS: In 55â 545 participants who were followed for a maximum of 21.5 years, 1085 were diagnosed with aortic stenosis and 615 were identified as having subsequent complications. Participants in the highest quintile of vitamin K1 intake had a 23% lower risk of aortic stenosis (hazard ratio, 0.77 [95% CI, 0.63-0.94]) and a 27% lower risk of aortic stenosis with subsequent complications (hazard ratio, 0.73 [95% CI, 0.56-0.95]), compared with participants in the lowest quintile after adjusting for demographics and cardiovascular risk factors. CONCLUSIONS: In this study, a high intake of vitamin K1-rich foods was associated with a lower incidence of aortic stenosis and a lower risk of aortic stenosis with subsequent complications.

BACKGROUND AND AIMS: A rising number of countries allow physicians to treat chronic pain with medical cannabis. However, recreational cannabis use has been linked with cardiovascular side effects, necessitating investigations concerning the safety of prescribed medical cannabis. METHODS: Using nationwide Danish registers, patients with chronic pain initiating first-time treatment with medical cannabis during 2018-21 were identified and matched 1:5 to corresponding control patients on age, sex, chronic pain diagnosis, and concomitant use of other pain medication. The absolute risks of first-time arrhythmia (atrial fibrillation/flutter, conduction disorders, paroxysmal tachycardias, and ventricular arrhythmias) and acute coronary syndrome were reported comparing medical cannabis use with no use. RESULTS: Among 1.88 million patients with chronic pain (46% musculoskeletal, 11% cancer, 13% neurological, and 30% unspecified pain), 5391 patients claimed a prescription of medical cannabis [63.2% women, median age: 59 (inter-quartile range 48-70) years] and were compared with 26 941 control patients of equal sex- and age composition. Arrhythmia was observed in 42 and 107 individuals, respectively, within 180 days. Medical cannabis use was associated with an elevated risk of new-onset arrhythmia {180-day absolute risk: 0.8% [95% confidence interval (CI) 0.6%-1.1%]} compared with no use [180-day absolute risk: 0.4% (95% CI 0.3%-0.5%)]: a risk ratio of 2.07 (95% CI 1.34-2.80) and a 1-year risk ratio of 1.36 (95% CI 1.00-1.73). No significant association was found for acute coronary syndrome [180-day risk ratio: 1.20 (95% CI 0.35-2.04)]. CONCLUSIONS: In patients with chronic pain, the use of prescribed medical cannabis was associated with an elevated risk of new-onset arrhythmia compared with no use-most pronounced in the 180 days following the initiation of treatment.

AIM: High-dose quadrivalent influenza vaccine (QIV-HD) has been shown to be more effective than standard-dose (QIV-SD) in reducing influenza infection, but whether diabetes status affects relative vaccine effectiveness (rVE) is unknown. We aimed to assess rVE on change in glycated haemoglobin [HbA1c (∆HbA1c)], incident diabetes, total all-cause hospitalizations (first + recurrent), and a composite of all-cause mortality and hospitalization for pneumonia or influenza. METHODS: DANFLU-1 was a pragmatic, open-label trial randomizing adults (65-79 years) 1:1 to QIV-HD or QIV-SD during the 2021/22 influenza season. Cox proportional hazards regression was used to estimate rVE against incident diabetes and the composite endpoint, negative binomial regression to estimate rVE against all-cause hospitalizations, and ANCOVA when assessing rVE against ∆HbA1c. RESULTS: Of the 12 477 participants, 1162 (9.3%) had diabetes at baseline. QIV-HD, compared with QIV-SD, was associated with a reduction in the rate of all-cause hospitalizations irrespective of diabetes [overall: 647 vs. 742 events, incidence rate ratio (IRR): 0.87, 95% CI (0.76-0.99); diabetes: 93 vs. 118 events, IRR: 0.80, 95% CI (0.55-1.15); without diabetes: 554 vs. 624 events, IRR: 0.88, 95% CI (0.76-1.01), pinteraction = 0.62]. Among those with diabetes, QIV-HD was associated with a lower risk of the composite outcome [2 vs. 11 events, HR: 0.18, 95% CI (0.04-0.83)] but had no effect on ∆HbA1c; QIV-HD adjusted mean difference: ∆ + 0.2 mmol/mol, 95% CI (-0.9 to 1.2). QIV-HD did not affect the risk of incident diabetes [HR 1.18, 95% CI (0.94-1.47)]. CONCLUSIONS: In this post-hoc analysis, QIV-HD versus QIV-SD was associated with an increased rVE against the composite of all-cause death and hospitalization for pneumonia/influenza, and the all-cause hospitalization rate irrespective of diabetes status.

AIMS: The present study aimed to determine the association between Type 2 diabetes mellitus (T2DM) and third-degree (complete) atrioventricular block. METHODS AND RESULTS: This nationwide nested case-control study included patients older than 18 years, diagnosed with third-degree atrioventricular block between 1 July 1995 and 31 December 2018. Data on medication, comorbidity, and outcomes were collected from Danish registries. Five controls, from the risk set of each case of third-degree atrioventricular block, were matched on age and sex to fit a Cox regression model with time-dependent exposure and time-dependent covariates. Subgroup analysis was conducted with Cox regression models for each subgroup. We located 25 995 cases with third-degree atrioventricular block that were matched with 130 004 controls. The mean age was 76 years and 62% were male. Cases had more T2DM (21% vs. 11%), hypertension (69% vs. 50%), atrial fibrillation (25% vs. 10%), heart failure (20% vs. 6.3%), and myocardial infarction (19% vs. 9.2%), compared with the control group. In Cox regression analysis, adjusting for comorbidities and atrioventricular nodal blocking agents, T2DM was significantly associated with third-degree atrioventricular block (hazard ratio: 1.63, 95% confidence interval: 1.57-1.69). The association remained in several subgroup analyses of diseases also suspected to be associated with third-degree atrioventricular block. There was a significant interaction with comorbidities of interest including hypertension, atrial fibrillation, heart failure, and myocardial infarction. CONCLUSION: In this nationwide study, T2DM was associated with a higher rate of third-degree atrioventricular block compared with matched controls. The association remained independent of atrioventricular nodal blocking agents and other comorbidities known to be associated with third-degree atrioventricular block.

BACKGROUND: Long-term prognostic implications of serial high-sensitivity troponin concentrations in subjects with suspected acute coronary syndrome are unknown. METHODS AND RESULTS: Individuals with a first diagnosis of myocardial infarction, unstable angina, observation for suspected myocardial infarction, or chest pain from 2012 through 2019 who underwent two high-sensitivity troponin-T (hsTnT) measurements 1-7 h apart were identified through Danish national registries. Absolute and relative risks for death at days 0-30 and 31-365, stratified for whether subjects had normal or elevated hsTnT concentrations, and whether these concentrations changed by <20%, > 20 to 50%, or >50% in either direction from first to second measurement, were calculated through multivariable logistic regression with average treatment effect modeling. Of the 28 902 individuals included, 2.8% had died at 30 days, whereas 4.9% of those who had survived the first 30 days died between days 31-365. The standardized risk of death was highest among subjects with two elevated hsTnT concentrations (0-30 days: 4.3%, 31-365 days: 7.2%). In this group, mortality was significantly higher in those with a > 20 to 50% or >50% rise from first to second measurement, though only at 30 days. The risk of death was very low in subjects with two normal hsTnT concentrations (0-30 days: 0.1%, 31-365 days: 0.9%) and did not depend on relative or absolute changes between measurements. CONCLUSIONS: Individuals with suspected acute coronary syndrome and two consecutively elevated hsTnT concentrations consistently had the highest risk of death. Mortality was very low in subjects with two normal hsTnT concentrations, irrespective of changes between measurements.

BACKGROUND: Alcoholic cardiomyopathy (ACM) is a form of dilated cardiomyopathy (DCM) occurring secondary to long-standing heavy alcohol use and is associated with poor outcomes, but the cause-specific risks are insufficiently understood. METHOD: Between 1997 and 2018, we identified all patients with a first diagnosis of ACM or DCM. The cumulative incidence of different causes of hospitalisation and mortality in the two groups was calculated using the Fine-Gray and Kaplan-Meier methods. RESULTS: A Total of 1,237 patients with ACM (mean age 56.3±10.1 years, 89% men) and 17,211 individuals with DCM (mean age 63.6±13.8 years, 71% men) were identified. Diabetes (10% vs 15%), hypertension (22% vs 31%), and stroke (8% vs 10%) were less common in ACM than DCM, whereas obstructive lung disease (15% vs 12%) and liver disease (17% vs 2%) were more prevalent (p<0.05). Cumulative 5-year mortality was 49% in ACM vs 33% in DCM, p<0.0001, multivariable adjusted hazards ratio 2.11 (95% confidence interval 1.97-2.26). The distribution of causes of death was similar in ACM and DCM, with the predominance of cardiovascular causes in both groups (42% in ACM vs 44% in DCM). 5-year cumulative incidence of heart failure hospitalisations (48% vs 54%) and any somatic cause (59% vs 65%) were also similar in ACM vs DCM. At 1 year, the use of beta blockers (55% vs 80%) and implantable cardioverter defibrillators (3% vs 14%) were significantly less often used in ACM vs DCM. CONCLUSIONS: Patients with ACM had similar cardiovascular risks and hospitalisation patterns as other forms of DCM, but lower use of guideline-directed cardiovascular therapies and greater mortality.

BACKGROUND: Anthracycline-based chemotherapy has improved the prognosis of various malignancies, but increases the long-term risk of heart failure (HF). Identification of patients at risk prior to treatment initiation is warranted. Therefore, the aim of this study was to evaluate if a familial predisposition to HF increases the risk of anthracycline related HF. METHODS: Using nationwide Danish registries, all patients treated with anthracycline from 2004 to 16 were identified. The primary outcome was long-term HF risk. First-degree relatives were identified in the Danish Family Registry and exposure was defined as a first-degree biological relative with prior HF. Risk of HF was evaluated in a cumulative incidence function and the association in a multivariable Cox regression model. RESULTS: A total of 11,651 patients (median age 49.1 years (IQR: 43.6-53.7), 12.2% male) were included after exclusion of 46 with preanthracycline HF. Median follow-up was 3.8 years (IQR 1.9-6.4). In the group with a first-degree relative with HF (n = 1,608) 35 patients (2.2%) were diagnosed with HF vs 133 (1.3%) in the group without a first-degree relative with HF (n = 10,043), corresponding to incidence rates per 1,000 patient-years of 5.2 (CI:3.8-7.3) vs 3.0 (CI:2.5-3.5). The cumulative incidence of HF after 10 years was higher in the first-degree relative group (3.2% vs 2.0%, P = .004); adjusted hazard ratio 1.53 (CI:1.05-2.23, P = .03). CONCLUSION: In this nationwide register-based study having a first-degree relative with HF was associated with increased risk of anthracycline related HF, suggesting that attention towards family predisposition may be warranted when estimating the risk of anthracycline related cardiotoxicity.
RESUMEN
AIMS: Atrial fibrillation (AF) and heart failure (HF) often coexist. However, whether AF onset before HF or vice versa is associated with the worst outcome remains unclear. A consensus of large studies can guide future research and preventive strategies to better target high-risk patients. METHODS AND RESULTS: We included all Danish cases with the coexistence of AF and HF (2005-17) using nationwide registries. Patients were divided into three separate groups (i) AF before HF, (ii) HF before AF, or (iii) AF and HF diagnosed concurrently (±30 days). Adjusting landmark Cox analyses (index date was the time of the latter diagnosis of AF or HF) were used for evaluating the association of the three groups with a composite outcome of ischaemic stroke or death. Among a total of 49 042 patients included, 40% had AF before HF, 27% had HF before AF, and 33% had AF and HF diagnosed concurrently. The composite endpoint accrued more often in patients with HF before AF compared to the two other groups (<0.001), and this remained significant in the adjusted analyses with hazard ratios (95% confidence intervals) of 1.26 (1.22-1.30) compared to AF before HF. Finally, antihypertensive treatment, oral anticoagulants, amiodarone, statins, and AF ablation were associated with a lower hazard ratio of the composite endpoint (all < 0.001). CONCLUSIONS: In this large Danish national cohort, diagnosis of HF before AF was associated with an increased absolute risk of death compared to AF before HF and AF and HF diagnosed concurrently. Antihypertensive treatment, oral anticoagulants, amiodarone, statins, and AF ablation may improve prognosis.

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: Limited data exist to describe the prognostic impact of atrial fibrillation (AF) and oral anticoagulation on patients with alcoholic cardiomyopathy (ACM) compared with dilated cardiomyopathy (DCM) and were investigated in this study. METHODS: Using Danish nationwide registries, a cohort analysis was conducted to assess the prognostic differences for patients with a first diagnosis of ACM versus DCM with and without AF 1994-2018 (followed until end 2019). Our study also assessed differences in mortality following initiation of anticoagulation in both populations. RESULTS: Totally, 1237 patients with ACM (33% with AF) and 17,211 individuals with DCM (33% with AF) were included. Those with ACM were more often men (89 versus 71%) and younger than patients with DCM (mean age 56 versus 64 years). Cumulative 5-year mortality was greater among patients with ACM, compared with DCM, regardless of AF (ACM with AF 49% [95% CI: 44-54%], ACM without AF 48% [45-53%], DCM with AF 41% [39-42%], DCM without AF 30% [29-31%], P < 0.0001). The prognosis associated with AF was statistically significantly different in people with ACM and DCM (adjusted hazards ratio 0.85 [95% CI: 0.74-0.98] versus 1.04 [1.00-1.09] in ACM and DCM, P < 0.0001). The mortality associated with oral anticoagulation was similar in ACM and DCM (hazards ratio 0.81 [0.61-1.07] versus 0.87 [0.80-0.94], P = 0.49). CONCLUSIONS: Patients with ACM had a worse prognosis when compared with patients with DCM, but this did not appear to be driven by AF. Patients with ACM were observed to have similar associated risk benefits of oral anticoagulation as DCM.

AIM: The COVID-19 pandemic resulted in a significant decrease in the number of hospital admissions for severe emergent cardiovascular diseases during lockdowns worldwide. This study aimed to determine the impact of both the first and the second Danish nationwide lockdown on the implantation rate of cardiac implantable electronic devices (CIEDs). METHODS: We retrospectively analysed the number of CIED implantations performed in Denmark and stratified them into 3-week intervals. RESULTS: The total number of de novo CIED implantations decreased during the first lockdown by 15.5% and during the second by 5.1%. Comparing each 3-week interval using rate ratios, a significant decrease in the daily rates of the total number of de novo and replacement CIEDs (0.82, 95% CI [0.70, 0.96]), de novo CIEDs only (0.82, 95% CI [0.69, 0.98]), and non-acute pacemaker implantations (0.80, 95% CI [0.63, 0.99]) was observed during the first interval of the first lockdown. During the second lockdown (third interval), a significant decrease was seen in the daily rates of de novo CIEDs (0.73, 95% CI [0.55, 0.97]), and of pacemakers in total during both the second (0.78, 95% CI [0.62, 0.97]) and the third (0.60, 95% CI [0.42, 0.85]) intervals. Additionally, the daily rates of acute pacemaker implantation decreased during the second interval (0.47, 95% CI [0.27, 0.79]) and of non-acute implantation during the third interval (0.57, 95% CI [0.38, 0.84]). A significant increase was observed in the number of replacement procedures during the first interval of the second lockdown (1.70, 95% CI [1.04, 2.85]). CONCLUSIONS: Our study found only modest changes in CIED implantations in Denmark during two national lockdowns.

AIM: To investigate trends in the utilization of transcatheter aortic valve replacement (TAVR) and changes in the characteristics of patients undergoing first-time TAVR. METHODS: Using Danish nationwide registers, we included all patients undergoing TAVR between 2008 and 2020. To compare patient characteristics, the study population was stratified according to calendar year of procedure: 2008-2010, 2011-2013, 2014-2016, and 2017-2020. RESULTS: We identified 6,097 patients undergoing TAVR with year-by-year increases in TAVR penetration rate. Over time, the age of the patients remained stable (2008-2010: median age 82 year [interquartile range (IQR): 77-86] vs 2017-2020: median age 81 years [IQR: 77-85]). Moreover, there was an increase in male patients (2008-2010: 49.9% vs 2017-2020: 57.4%) and patients with diabetes (2008-2010: 14.2% vs 2017-2020: 19.2%). Conversely, a history of stroke (2008-2010: 15.8% vs 2017-2020: 13.1%), previous myocardial infarction (2008-2010: 22.4% vs 2017-2020: 10.0%), heart failure (2008-2010: 40.5% vs 2017-2020: 25.2%), and peripheral artery disease (2008-2010: 14.8% vs 2017-2020: 10.4) decreased among patients. CONCLUSIONS: TAVR utilization increased markedly in the years 2008-2020. Patients undergoing TAVR had less comorbidity over time while age remained stable. Thus, despite expanding to patients at lower surgical risk, TAVR is still offered mainly to older patients.

OBJECTIVE: To investigate the long-term rates of heart failure (HF) and other adverse cardiovascular outcomes, including arrhythmias, myocardial infarction, ischaemic stroke, venous thromboembolism, pulmonary hypertension and pericarditis, in SSc patients according to gender and age. METHODS: Using Danish nationwide registries, SSc patients (diagnosed from 1996 to 2018) were matched with four controls from the background population by gender, age and comorbidities. Cox regression was used to compare the rates of cardiovascular outcomes between SSc patients and controls and the rate of mortality between SSc patients developing HF and HF patients without SSc, according to gender and age (above/below median). RESULTS: In total, 1569 SSc patients were matched with 6276 non-SSc controls (median age 55 years, 80.4% women, median follow-up 7.3 years). SSc had a higher rate of HF in both women [HR 2.99 (95% CI 2.18, 4.09)] and men [HR 3.01 (1.83, 4.95)] (Pinteraction = 0.88), with similar trends for other cardiovascular outcomes. SSc had a higher rate of HF in patients <55 years of age [HR 4.14 (95% CI 2.54, 6.74)] and ≥55 years [HR 2.74 (1.98, 3.78)] (Pinteraction = 0.22), with similar trends for other cardiovascular outcomes. SSc patients with new-onset HF had a higher rate of mortality than HF patients without a history of SSc, irrespective of gender (Pinteraction = 0.53) and age (Pinteraction = 0.43). CONCLUSIONS: SSc was associated with higher rates of HF and other cardiovascular outcomes than matched controls, irrespective of gender and age. Among patients with new-onset HF, a history of SSc was associated with higher mortality.

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-19 and HbA1c < 48 mmol/mol or HbA1c > 64 mmol/mol had a higher associated risk of the composite outcome. Similarly, among patients without diabetes, varying HbA1c levels were associated with higher risk of the composite outcome.

AIMS: A few studies suggested that epilepsy and antiepileptic drugs with sodium channel-blocking properties were independently associated with out-of-hospital cardiac arrest (OHCA). However, these findings have not yet been replicated. METHODS: Using Danish registries, we conducted a nested case-control study in a cohort of individuals between 1 June 2001 and 31 December 2015. Cases were defined as OHCA from presumed cardiac causes, and were matched with non-OHCA-controls based on sex, and age on the date of OHCA. Exposure of interest was epilepsy or antiepileptic drug use. To study the association between individual antiepileptic drug use and the rate of OHCA, we compared each antiepileptic drug with valproic acid. Cox regression with time-dependent covariates was conducted to calculate hazard ratio (HR) and 95% confidence interval (CI). RESULTS: We identified 35 195 OHCA-cases and 351 950 matched non-OHCA controls. Epilepsy (cases: 3.58%, controls: 1.60%) was associated with increased rate of OHCA compared with the general population (HR: 1.76, 95%CI: 1.64-1.88) when common OHCA risk factors were taken into account. When we studied antiepileptic drug use, we found that 2 antiepileptic drugs without sodium channel blockage, clonazepam (HR: 1.88, 95%CI: 1.45-2.44) and pregabalin (HR: 1.33, 95%CI: 1.05-1.69), were associated with OHCA, whereas none of the antiepileptic drugs with sodium channel blockage were associated with OHCA. CONCLUSION: Epilepsy is associated with increased rate of OHCA. Our findings do not support a possible association between antiepileptic drugs with sodium channel-blocking properties and OHCA.

AIMS: Opioid use has substantially increased in the last decade and is associated with overdose mortality, but also with increased mortality from cardiovascular causes. This finding may partly reflect an association between opioids and out-of-hospital cardiac arrest (OHCA). Therefore, we aimed to investigate OHCA-risk of opioids in the community. METHODS: We conducted 2 population-based case-control studies separately in the Netherlands (2009-2018) and Denmark (2001-2015). Cases were individuals who experienced OHCA of presumed cardiac cause. Each case was matched with up to 5 non-OHCA-controls according to age, sex and OHCA-date. Conditional logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: We included 5473 OHCA-cases matched with 21 866 non-OHCA-controls in the Netherlands, and 35 017 OHCA-cases matched with 175 085 non-OHCA-controls in Denmark. We found that use of opioids (the Netherlands: cases: 5.4%, controls: 1.8%; Denmark: cases: 11.9%, controls: 4.4%) was associated with increased OHCA-risk in both regions (the Netherlands: OR 2.1 [95% CI 1.8-2.5]; Denmark: OR 1.8 [95% CI 1.5-2.1]). The association was observed in both sexes, and in individuals with cardiovascular disease (the Netherlands: OR 1.8 [95% CI 1.5-2.1]; Denmark: OR 1.6 [95% CI 1.5-1.7]) or without (the Netherlands: OR 3.4 [95% CI: 2.4-4.8], Pinteraction < .0001; Denmark: OR 2.3 [95% CI: 2.0-2.5], Pinteraction < .0001). CONCLUSION: Use of opioids is associated with increased OHCA-risk in both sexes, independently of concomitant cardiovascular disease. These findings should be considered when evaluating the harms and benefits of treatment with opioids.

AIMS: Drugs that prolong the QT interval, either by design (cardiac QT-prolonging drugs: anti-arrhythmics) or as off-target effect (non-cardiac QT-prolonging drugs), may increase the risk of ventricular arrhythmias and out-of-hospital cardiac arrest (OHCA). Risk mitigation measures were instituted, in particular, surrounding prescription of cardiac QT-prolonging drugs. We studied OHCA risk of both drug types in current clinical practice. METHODS: Using data from large population-based OHCA registries in the Netherlands and Denmark, we conducted two independent case-control studies. OHCA cases with presumed cardiac causes were matched on age/sex/index date with up to five non-OHCA controls. We calculated odds ratios (ORs) for the association of cardiac or non-cardiac QT-prolonging drugs with OHCA risk using conditional logistic regression analyses. RESULTS: We identified 2503 OHCA cases and 10 543 non-OHCA controls in the Netherlands, and 35 017 OHCA cases and 175 085 non-OHCA controls in Denmark. Compared to no use of QT-prolonging drugs, use of non-cardiac QT-prolonging drugs (Netherlands: cases: 3.0%, controls: 1.9%; Denmark: cases: 14.9%, controls: 7.5%) was associated with increased OHCA risk (Netherlands: OR 1.37 [95% CI: 1.03-1.81]; Denmark: OR 1.63 [95% CI: 1.57-1.70]). The association between cardiac QT-prolonging drugs (Netherlands: cases: 4.0%, controls: 2.5%; Denmark: cases: 2.1%, controls: 0.9%) and OHCA was weaker (Netherlands: OR 1.17 [95% CI: 0.92-1.50]; Denmark: OR 1.21 [95% CI: 1.09-1.33]), although users of cardiac QT-prolonging drugs had more medication use and comorbidities associated with OHCA risk than users of non-cardiac QT-prolonging drugs. CONCLUSION: In clinical practice, cardiac QT-prolonging drugs confer lower OHCA risk than non-cardiac QT-prolonging drugs, although users of the former have higher a priori risk. This is likely due to risk mitigation measures surrounding prescription of cardiac QT-prolonging drugs.

Conflicting results have been reported regarding the association between antidepressant use and out-of-hospital cardiac arrest (OHCA) risk. We investigated whether the use of antidepressants is associated with OHCA. METHODS: We conducted a nationwide nested case-control study to assess the association of individual antidepressant drugs within drug classes with the hazard of OHCA. Cases were defined as OHCA from presumed cardiac causes. Cox regression with time-dependent exposure and time-dependent covariates was conducted to calculate hazard ratios (HR) and 95% confidence intervals (95% CIs) overall and in subgroups defined by established cardiac disease and cardiovascular risk factors. Also, we studied antidepressants with and without sodium channel blocking or potassium channel blocking properties separately. RESULTS: During the study period from 2001 to 2015 we observed 10 987 OHCA cases, and found increased OHCA rate for high-dose citalopram (>20 mg) and high-dose escitalopram (>10 mg; HR:1.46 [95% CI:1.27-1.69], HR:1.43 [95% CI:1.16-1.75], respectively) among selective serotonin reuptake inhibitors (reference drug sertraline), and for high-dose mirtazapine (>30; HR:1.59 [95% CI:1.18-2.14]) among the serotonin-norepinephrine reuptake inhibitors or noradrenergic and specific serotonergic antidepressants (reference drug duloxetine). Among tricyclic antidepressants (reference drug amitriptyline), no drug was associated with significantly increased OHCA rate. Increased OHCA rate was found for antidepressants with known potassium channel blocking properties (HR:1.14 [95% CI:1.05-1.23]), but for not those with sodium channel blocking properties. Citalopram, although not statistically significant, and mirtazapine were associated with increased OHCA rate in patients without cardiac disease and cardiovascular risk factors. CONCLUSION: Our findings indicate that careful titration of citalopram, escitalopram and mirtazapine dose may have to be considered due to drug safety issues.

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.

BACKGROUND: Ruptured aortic aneurysm and aortic dissections are potentially preventable disorders associated with high mortality. Screening of individuals at risk may translate into elective surgical interventions and lowered mortality. It is uncertain if the risk of aortic dilation of varying degrees aggregates within families. METHODS: We investigated the risk of having thoracic and abdominal aortic sizes in the highest quartile (measured by computed tomography scans and indexed for body size) if at least 1 parent did so in the Framingham Heart Study cohorts, and estimated the incidence rates and hazard ratios of developing aortic aneurysm or dissection among first-degree relatives of those with aortic aneurysm or dissection, in comparison with age- and sex-matched controls (1:10 for aortic aneurysm and 1:100 for aortic dissection) using the Danish nationwide administrative registries. RESULTS: In the Framingham Heart Study, offspring (n=235) whose parent(s) had a sex- and age-standardized aortic size in the upper quartile had a multivariable-adjusted ≈3-fold increased odds ratio of belonging to the upper quartile themselves. In Denmark, a total of 68 939 individuals (mean age, 42 years) had a first-degree relative with aortic aneurysm and 7209 persons (mean age, 39 years) had a first-degree relative with aortic dissection. During an average follow-up of 7 years, first-degree relatives of patients with aortic aneurysm and dissection had a hazard ratio of 6.70 (95% CI, 5.96-7.52) for developing aortic aneurysm and a hazard ratio of 9.24 (95% CI, 5.53-15.44) for dissection in comparison with matched controls. These estimates remained unchanged on adjusting for several comorbidities, including prevalent hypertension, bicuspid aortic valve, and the Marfan syndrome. For both aortic aneurysm and dissections, the absolute event rates approached 1 per 1000 person-years for first-degree relatives versus 11 to 13 (aortic aneurysm) and 2 to 3 (aortic dissections) per 100 000 person-years among controls. CONCLUSIONS: Increased aortic size, a precursor of aortic aneurysm and a risk factor for dissection, clusters in families. The incidence rates of aortic aneurysm and dissections approach the incidence rates of other common cardiovascular conditions in first-degree relatives, supporting the use of systematic screening for these conditions.
