Abstract
BACKGROUND Most trials that have shown a benefit of beta-blocker treatment after myocardial infarction included patients with large myocardial infarctions and were conducted in an era before modern biomarker-based diagnosis of myocardial infarction and treatment with percutaneous coronary intervention, antithrombotic agents, high-intensity statins, and renin-angiotensin-aldosterone system antagonists. METHODS In a parallel-group, open-label trial performed at 45 centers in Sweden, Estonia, and New Zealand, we randomly assigned patients with an acute myocardial infarction who had undergone coronary angiography and had a left ventricular ejection fraction of at least 50% to receive either long-term treatment with a beta-blocker (metoprolol or bisoprolol) or no beta-blocker treatment. The primary end point was a composite of death from any cause or new myocardial infarction. RESULTS From September 2017 through May 2023, a total of 5020 patients were enrolled (95.4% of whom were from Sweden). The median follow-up was 3.5 years (interquartile range, 2.2 to 4.7). A primary end-point event occurred in 199 of 2508 patients (7.9%) in the beta-blocker group and in 208 of 2512 patients (8.3%) in the no-beta-blocker group (hazard ratio, 0.96; 95% confidence interval, 0.79 to 1.16; P = 0.64). Beta-blocker treatment did not appear to lead to a lower cumulative incidence of the secondary end points (death from any cause, 3.9% in the beta-blocker group and 4.1% in the no-beta-blocker group; death from cardiovascular causes, 1.5% and 1.3%, respectively; myocardial infarction, 4.5% and 4.7%; hospitalization for atrial fibrillation, 1.1% and 1.4%; and hospitalization for heart failure, 0.8% and 0.9%). With regard to safety end points, hospitalization for bradycardia, second- or third-degree atrioventricular block, hypotension, syncope, or implantation of a pacemaker occurred in 3.4% of the patients in the beta-blocker group and in 3.2% of those in the no-beta-blocker group; hospitalization for asthma or chronic obstructive pulmonary disease in 0.6% and 0.6%, respectively; and hospitalization for stroke in 1.4% and 1.8%. CONCLUSIONS Among patients with acute myocardial infarction who underwent early coronary angiography and had a preserved left ventricular ejection fraction (≥50%), long-term beta-blocker treatment did not lead to a lower risk of the composite primary end point of death from any cause or new myocardial infarction than no beta-blocker use.

Abstract
AIMS The European Unified Registries On Heart care Evaluation And Randomized Trials (EuroHeart) aims to improve the quality of care and clinical outcomes for patients with cardiovascular disease. The collaboration of acute coronary syndrome/percutaneous coronary intervention (ACS/PCI) registries is operational in seven vanguard European Society of Cardiology member countries. METHODS AND RESULTS Adults admitted to hospitals with ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) are included, and individual patient-level data collected and aligned according to the internationally agreed EuroHeart data standards for ACS/PCI. The registries provide up to 155 variables spanning patient demographics and clinical characteristics, in-hospital care, in-hospital outcomes, and discharge medications. After performing statistical analyses on patient data, participating countries transfer aggregated data to EuroHeart for international reporting.Between 1st January 2022 and 31st December 2022, 40 021 admissions (STEMI 46.7%, NSTEMI 53.3%) were recorded from 192 hospitals in the seven vanguard countries: Estonia, Hungary, Iceland, Portugal, Romania, Singapore, and Sweden. The mean age for the cohort was 67.9 (standard deviation 12.6) years, and it included 12 628 (31.6%) women. CONCLUSION The EuroHeart collaboration of ACS/PCI registries prospectively collects and analyses individual data for ACS and PCI at a national level, after which aggregated results are transferred to the EuroHeart Data Science Centre. The collaboration will expand to other countries and provide continuous insights into the provision of clinical care and outcomes for patients with ACS and undergoing PCI. It will serve as a unique international platform for quality improvement, observational research, and registry-based clinical trials.

Abstract
AIMS Takotsubo syndrome (TS) is a heart condition mimicking acute myocardial infarction. TS is characterized by a sudden weakening of the heart muscle, usually triggered by physical or emotional stress. In this study, we aimed to investigate the effect of pharmacological interventions on short- and long-term mortality in patients with TS. METHODS AND RESULTS We analysed data from the SWEDEHEART (the Swedish Web System for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies) registry, which included patients who underwent coronary angiography between 2009 and 2016. In total, we identified 1724 patients with TS among 228 263 individuals in the registry. The average age was 66 ± 14 years, and 77% were female. Nearly half of the TS patients (49.4%) presented with non-ST-elevation acute coronary syndrome, and a quarter (25.9%) presented with ST-elevation myocardial infarction. Most patients (79.1%) had non-obstructive coronary artery disease on angiography, while 11.7% had a single-vessel disease and 9.2% had a multivessel disease. All patients received at least one pharmacological intervention; most of them used beta-blockers (77.8% orally and 8.3% intravenously) or antiplatelet agents [aspirin (66.7%) and P2Y12 inhibitors (43.6%)]. According to the Kaplan-Meier estimator, the probability of all-cause mortality was 2.5% after 30 days and 16.6% after 6 years. The median follow-up time was 877 days. Intravenous use of inotropes and diuretics was associated with increased 30 day mortality in TS [hazard ratio (HR) = 9.92 (P < 0.001) and HR = 3.22 (P = 0.001), respectively], while angiotensin-converting enzyme inhibitors and statins were associated with decreased long-term mortality [HR = 0.60 (P = 0.025) and HR = 0.62 (P = 0.040), respectively]. Unfractionated and low-molecular-weight heparins were associated with reduced 30 day mortality [HR = 0.63 (P = 0.01)]. Angiotensin receptor blockers, oral anticoagulants, P2Y12 antagonists, aspirin, and beta-blockers did not statistically correlate with mortality. CONCLUSIONS Our findings suggest that some medications commonly used to treat TS are associated with higher mortality, while others have lower mortality. These results could inform clinical decision-making and improve patient outcomes in TS. Further research is warranted to validate these findings and to identify optimal pharmacological interventions for patients with TS.

Abstract
BACKGROUND Previous studies on disparities in healthcare and outcome have shown conflicting results. The aim of this study was to assess differences in baseline characteristics, management, and outcome in myocardial infarction (MI) patients, by country of birth. METHODS In total, 194 259 MI patients (64% male, 15% foreign-born) from the nationwide SWEDEHEART registry were included and compared by geographic region of birth. The primary outcome was one-year major adverse cardiovascular events (MACE) including all-cause death, MI, and stroke. Secondary outcomes were long-term MACE (up to 12 years), the individual components of MACE, 30-day mortality, management, and risk factors. Logistic regression, Cox proportional hazard models and propensity score matching (PSM), accounting for baseline differences, were used. RESULTS Foreign-born patients were younger, often male, and had a higher cardiovascular (CV) risk factor burden, including smoking, diabetes, and hypertension. In PSM analyses, Asia-born patients had higher likelihood of revascularisation (OR 1.16, 95% CI 1.04-1.30), statins and betablocker prescription at discharge and a 34% lower risk of 30-day mortality. Furthermore, no statistically significant differences were found in the primary outcomes except for Asia-born patients having lower risk of one-year MACE (HR 0.85, 95% CI 0.73-0.98), driven by lower mortality (HR 0.72, 95% CI 0.57-0.91). The results persisted over long-term follow-up. CONCLUSIONS This study shows that in a system with universal healthcare coverage in which acute and secondary preventive treatments do not differ by country of birth, foreign-born patients, despite higher CV risk factor burden, will do at least as well as native-born patients.

Abstract
Reduced lung function is associated with cardiovascular mortality, but the relationships with atherosclerosis are unclear. The population-based Swedish CArdioPulmonary BioImage study measured lung function, emphysema, coronary CT angiography, coronary calcium, carotid plaques and ankle-brachial index in 29,593 men and women aged 50-64 years. The results were confirmed using 2-sample Mendelian randomization. Lower lung function and emphysema were associated with more atherosclerosis, but these relationships were attenuated after adjustment for cardiovascular risk factors. Lung function was not associated with coronary atherosclerosis in 14,524 never-smokers. No potentially causal effect of lung function on atherosclerosis, or vice versa, was found in the 2-sample Mendelian randomization analysis. Here we show that reduced lung function and atherosclerosis are correlated in the population, but probably not causally related. Assessing lung function in addition to conventional cardiovascular risk factors to gauge risk of subclinical atherosclerosis is probably not meaningful, but low lung function found by chance should alert for atherosclerosis.

Abstract
BACKGROUND Worldwide, there is a large and growing group of older adults. Frailty is known as an important discriminatory factor for poor outcomes. The Clinical Frailty Scale (CFS) has become a frequently used frailty instrument in different clinical settings and health care sectors, and it has shown good predictive validity. The aims of this study were to describe and validate the translation and cultural adaptation of the CFS into Swedish (CFS-SWE), and to test the inter-rater reliability (IRR) for registered nurses using the CFS-SWE. METHODS An observational study design was employed. The ISPOR principles were used for the translation, linguistic validation and cultural adaptation of the scale. To test the IRR, 12 participants were asked to rate 10 clinical case vignettes using the CFS-SWE. The IRR was assessed using intraclass correlation and Krippendorff's alpha agreement coefficient test. RESULTS The Clinical Frailty Scale was translated and culturally adapted into Swedish and is presented in its final form. The IRR for all raters, measured by an intraclass correlation test, resulted in an absolute agreement value among the raters of 0.969 (95% CI: 0.929-0.991) and a consistency value of 0.979 (95% CI: 0.953-0.994), which indicates excellent reliability. Krippendorff's alpha agreement coefficient for all raters was 0.969 (95% CI: 0.917-0.988), indicating near-perfect agreement. The sensitivity of the reliability was examined by separately testing the IRR of the group of specialised registered nurses and non-specialised registered nurses respectively, with consistent and similar results. CONCLUSION The Clinical Frailty Scale was translated, linguistically validated and culturally adapted into Swedish following a well-established standard technique. The IRR was excellent, judged by two established, separately used, reliability tests. The reliability test results did not differ between non-specialised and specialised registered nurses. However, the use of case vignettes might reduce the generalisability of the reliability findings to real-life settings. The CFS has the potential to be a common reference tool, especially when older adults are treated and rehabilitated in different care sectors.

Abstract
AIMS Ticagrelor is associated with a lower risk of ischemic events than clopidogrel. However, it is uncertain whether the benefits of more intensive anti-ischemic therapy outweigh the risks of major bleeding in patients who have a high bleeding risk (HBR). Therefore, this study compared ticagrelor and clopidogrel in myocardial infarction (MI) patients with HBR. METHODS AND RESULTS This study included all patients enrolled in the SWEDEHEART registry who were discharged with dual antiplatelet therapy using ticagrelor or clopidogrel following MI between 2010 and 2017. High bleeding risk was defined as a PRECISE-DAPT score ≥25. Information on ischemic events, major bleeding, and mortality was obtained from national registries, with 365 days of follow-up. Additional outcomes include major adverse cardiovascular events (MACE), a composite of MI, stroke and all-cause mortality, and net adverse clinical events (NACE), a composite of MACE and bleeding. This study included 25 042 HBR patients, of whom 11 848 were treated with ticagrelor. Ticagrelor was associated with a lower risk of MI, stroke, and MACE, but a higher risk of bleeding compared to clopidogrel. There were no significant differences in mortality and NACE. Additionally, when examining the relationship between antiplatelet therapy and bleeding risk in 69 040 MI patients, we found no statistically significant interactions between the PRECISE-DAPT score and treatment effect. CONCLUSIONS We observed no difference in NACE when comparing ticagrelor and clopidogrel in HBR patients. Moreover, we found no statistically significant interactions between bleeding risk and the comparative effectiveness of clopidogrel and ticagrelor in a larger population of MI patients.

Abstract
OBJECTIVES To investigate the association between type I collagen α1 chain (COL1α1) levels and coronary artery disease (CAD) by using absolute quantification in plasma. Also, to investigate the correlates of COL1α1 to clinical characteristics and circulating markers of collagen metabolism. DESIGN Life conditions, Stress and Health (LSH) study: prospective cohort study, here with a nested case-control design.Assessing Platelet Activity in Coronary Heart Disease (APACHE) study: prospective cohort study. SETTING LSH: primary care setting, southeast Sweden.APACHE: cardiology department, university hospital, southeast Sweden. PARTICIPANTS LSH: 1007 randomly recruited individuals aged 45-69 (50% women). Exclusion criteria was serious disease. After 13 years of follow-up, 86 cases with primary endpoint were identified and sex-matched/age-matched to 184 controls. APACHE 125 patients with myocardial infarction (MI), 73 with ST-elevation MI and 52 with non-ST-elevation MI. EXCLUSION CRITERIA Intervention study participation, warfarin treatment and short life expectancy. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome was the association between baseline COL1α1 and first-time major event of CAD, defined as fatal/non-fatal MI or coronary revascularisation after 13 years. Secondary outcomes were the association between the collagen biomarkers PRO-C1 (N-terminal pro-peptide of type I collagen)/C1M (matrix metalloproteinase-mediated degradation of type I collagen) and CAD; temporal change of COL1α1 after acute MI up to 6 months and lastly, correlates between COL1α1 and patient characteristics along with circulating markers of collagen metabolism. RESULTS COL1α1 levels were associated with CAD, both unadjusted (HR=0.69, 95% CI=0.56 to 0.87) and adjusted (HR=0.55, 95% CI=0.41 to 0.75). PRO-C1 was associated with CAD, unadjusted (HR=0.62, 95% CI=0.47 to 0.82) and adjusted (HR=0.61, 95% CI=0.43 to 0.86), while C1M was not. In patients with MI, COL1α1 remained unchanged up to 6 months. COL1α1 was correlated to PRO-C1, but not to C1M. CONCLUSIONS Plasma COL1α1 was independently and inversely associated with CAD. Furthermore, COL1α1 appeared to reflect collagen synthesis but not degradation. Future studies are needed to confirm whether COL1α1 is a clinically useful biomarker of CAD.

Abstract
OBJECTIVE To assess the contemporary prevalence of, and factors associated with angina pectoris symptoms, and to examine the relationship to coronary atherosclerosis in a middle-aged, general population. METHODS Data were based on the Swedish CArdioPulmonary bioImage Study (SCAPIS), in which 30 154 individuals were randomly recruited from the general population between 2013 and 2018. Participants that completed the Rose Angina Questionnaire were included and categorised as angina or no angina. Subjects with a valid coronary CT angiography (CCTA) were categorised by degree of coronary atherosclerosis; ≥50% obstruction (obstructive coronary atherosclerosis), <50% obstruction or any atheromatosis (non-obstructive coronary atherosclerosis) or none (no coronary atherosclerosis). RESULTS The study population consisted of 28 974 questionnaire responders (median age 57.4 years, female 51.6%, hypertension 19.9%, hyperlipidaemia 7.9%, diabetes mellitus 3.7%), of which 1025 (3.5%) fulfilled the criteria of angina. Coronary atherosclerosis was more common in individuals having angina compared with those with no angina (n=24 602, obstructive coronary atherosclerosis 11.8% vs 5.4%, non-obstructive coronary atherosclerosis 38.9% vs 37.0%, no coronary atherosclerosis 49.4% vs 57.7%, all p<0.001). Factors independently associated with angina were birthplace outside of Sweden (OR 2.58 (95% CI 2.10 to 2.92)), low educational level (OR 1.41 (1.10 to 1.79)), unemployment (OR 1.51 (1.27 to 1.81)), poor economic status (OR 1.85 (1.38 to 2.47)), symptoms of depression (OR 1.63 (1.38 to 1.92)) and high degree of stress (OR 2.92 (1.80 to 4.73)). CONCLUSION Angina pectoris symptoms are common (3.5%) among middle-aged individuals of the general population of Sweden, though with low association to obstructive coronary atherosclerosis. Sociodemographic and psychological factors are highly associated with angina symptoms, irrespective of degree of coronary atherosclerosis.

Abstract
Despite abundant knowledge about the relationship between inflammation and coronary atherosclerosis, it is still unknown whether systemic inflammation measured as high-sensitivity C-reactive protein (hsCRP) is associated with coronary atherosclerosis in a general population. This study aimed to examine the association between hsCRP and coronary computed tomography angiography (CCTA)-detected coronary atherosclerosis in a population-based cohort. Out of 30,154 randomly invited men and women aged 50 to 64 years in the Swedish Cardiopulmonary Bioimage Study (SCAPIS), 25,408 had a technically acceptable CCTA and analysed hsCRP. Coronary atherosclerosis was defined as presence of plaque of any degree in any of 18 coronary segments. HsCRP values were categorised in four groups. Compared with hsCRP below the detection limit, elevated hsCRP (≥ 2.3 mg/L) was weakly associated with any coronary atherosclerosis (OR 1.15, 95% CI 1.07-1.24), coronary diameter stenosis ≥ 50% (OR 1.27, 95% CI 1.09-1.47), ≥ 4 segments involved (OR 1.13, 95% CI 1.01-1.26 ) and severe atherosclerosis (OR 1.33, 95% CI 1.05-1.69) after adjustment for age, sex and traditional risk factors. The associations were attenuated after further adjustment for body mass index (BMI), although elevated hsCRP still associated with noncalcified plaques (OR 1.16, 95% CI 1.02-1.32), proposed to be more vulnerable. In conclusion, the additional value of hsCRP to traditional risk factors in detection of coronary atherosclerosis is low. The association to high-risk noncalcified plaques, although unlikely through a causal pathway, could explain the relationship between hsCRP and clinical coronary events in numerous studies.

Abstract
OBJECTIVE Beta-blockers (BB) are an established treatment following myocardial infarction (MI). However, there is uncertainty as to whether BB beyond the first year of MI have a role in patients without heart failure or left ventricular systolic dysfunction (LVSD). METHODS A nationwide cohort study was conducted including 43 618 patients with MI between 2005 and 2016 in the Swedish register for coronary heart disease. Follow-up started 1 year after hospitalisation (index date). Patients with heart failure or LVSD up until the index date were excluded. Patients were allocated into two groups according to BB treatment. Primary outcome was a composite of all-cause mortality, MI, unscheduled revascularisation and hospitalisation for heart failure. Outcomes were analysed using Cox and Fine-Grey regression models after inverse propensity score weighting. RESULTS Overall, 34 253 (78.5%) patients received BB and 9365 (21.5%) did not at the index date 1 year following MI. The median age was 64 years and 25.5% were female. In the intention-to-treat analysis, the unadjusted rate of primary outcome was lower among patients who received versus not received BB (3.8 vs 4.9 events/100 person-years) (HR 0.76; 95% CI 0.73 to 1.04). Following inverse propensity score weighting and multivariable adjustment, the risk of the primary outcome was not different according to BB treatment (HR 0.99; 95% CI 0.93 to 1.04). Similar findings were observed when censoring for BB discontinuation or treatment switch during follow-up. CONCLUSION Evidence from this nationwide cohort study suggests that BB treatment beyond 1 year of MI for patients without heart failure or LVSD was not associated with improved cardiovascular outcomes.

Abstract
The TACSI trial (ClinicalTrials.gov Identifier: NCT03560310) tests the hypothesis that 1-year treatment with dual antiplatelet therapy with acetylsalicylic acid (ASA) and ticagrelor is superior to only ASA after isolated coronary artery bypass grafting (CABG) in patients with acute coronary syndrome. The TACSI trial is an investigator-initiated pragmatic, prospective, multinational, multicenter, open-label, registry-based randomized trial with 1:1 randomization to dual antiplatelet therapy with ASA and ticagrelor or ASA only, in patients undergoing first isolated CABG, with a planned enrollment of 2200 patients at Nordic cardiac surgery centers. The primary efficacy end point is a composite of time to all-cause death, myocardial infarction, stroke, or new coronary revascularization within 12 months after randomization. The primary safety end point is time to hospitalization due to major bleeding. Secondary efficacy end points include time to the individual components of the primary end point, cardiovascular death, and rehospitalization due to cardiovascular causes. High-quality health care registries are used to assess primary and secondary end points. The patients will be followed for 10 years. The TACSI trial will give important information useful for guiding the antiplatelet strategy in acute coronary syndrome patients treated with CABG.

Abstract
BACKGROUND Interventions promoting adherence to exercise-based cardiac rehabilitation (exCR) are important to achieve positive physical and psychological outcomes, but knowledge of the added value of behavioral medicine interventions for these measures is limited. The aim of the study was to investigate the added value of a behavioral medicine intervention in physical therapy (BMIP) in routine exCR on psychological outcomes and health-related quality of life (HRQoL) versus routine exCR alone (RC). METHODS A total of 170 patients with coronary artery disease (136 men), mean age 62.3 ± 7.9 years, were randomized at a Swedish university hospital to a BMIP plus routine exCR or to RC for four months. The outcome assessments included HRQoL (SF-36, EQ-5D), anxiety and depression (HADS), patient enablement and self-efficacy and was performed at baseline, four and 12 months. Between-group differences were tested with an independent samples t-test and, for comparisons within groups, a paired t-test was used. An intention-to-treat and a per-protocol analysis were performed. RESULTS No significant differences in outcomes between the groups were shown between baseline and four months or between four and 12 months. Both groups improved in most SF-36 domains, EQ-VAS and HADS anxiety at the four-month follow-up and sufficient enablement remained at the 12-months follow-up. CONCLUSION A BMIP added to routine exCR care had no significant effect on psychological outcomes and HRQoL compared with RC, but significant improvements in several measures were shown in both groups at the four-month follow-up. Since recruited participants showed a better psychological profile than the general coronary artery disease population, further studies on BMIP in exCR, tailored to meet individual needs in broader patient groups, are needed. Trial registration number NCT02895451, 09/09/2016, retrospectively registered.

Abstract
OBJECTIVES Previous studies have described impaired platelet function after cardiopulmonary bypass (CPB). Whether this is still valid in contemporary cardiac surgery is unclear. This study aimed to quantify changes in function and number of platelets during CPB in a present-day cardiac surgery cohort. DESIGN Prospective, controlled clinical study. SETTING A single-center university hospital. PARTICIPANTS Thirty-nine patients scheduled for coronary artery bypass graft surgery with CPB. INTERVENTIONS Platelet function and numbers were measured at 6 timepoints in 39 patients during and after coronary artery bypass graft surgery; at baseline before anesthesia, at the end of CPB, after protamine administration, at intensive care unit (ICU) arrival, 3 hours after ICU arrival, and on the morning after surgery. MEASUREMENTS AND MAIN RESULTS Platelet function was assessed with impedance aggregometry and flow cytometry. Platelet numbers are expressed as actual concentration and as numbers corrected for dilution using hemoglobin as a reference marker. There was no consistent impairment of platelet function during CPB with either impedance aggregometry or flow cytometry. After protamine administration, a decrease in platelet function was seen with impedance aggregometry and for some markers of activation with flow cytometry. Platelet function was restored 3 hours after arrival in the ICU. During CPB (85.0 ± 21 min), the number of circulating platelets corrected for dilution increased from 1.73 ± 0.42 × 109/g to 1.91 ± 0.51 × 109/g (p < 0.001). CONCLUSIONS During cardiac surgery with moderate CPB times, platelet function was not impaired, and no consumption of circulating platelets could be detected. Administration of protamine transiently affected platelet function.

Abstract
BACKGROUND Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome without any evidence-based treatment options. No treatment for TS has been examined in a randomized trial. STUDY DESIGN AND OBJECTIVES BROKEN-SWEDEHEART is a multicenter, randomized, open-label, registry-based 2 × 2 factorial clinical trial in patients with TS designed to test whether treatment with adenosine and dipyridamole accelerates cardiac recovery and improves clinical outcomes compared to standard care (study 1); and apixaban reduces the risk of thromboembolic events compared to no treatment with antithrombotic drugs (study 2). The trial will enroll 1,000 patients. Study 1 (adenosine hypothesis) will evaluate 2 coprimary end points: (1) wall motion score index at 48 to 96 hours (evaluated in the first 200 patients); and (2) the composite of death, cardiac arrest, need for mechanical assist device or heart failure hospitalization within 30 days or left ventricular ejection fraction <50% at 48 to 96 hours (evaluated in 1,000 patients). The primary end point in study 2 (apixaban hypothesis) is the composite of death or thromboembolic events within 30 days or the presence of intraventricular thrombus on echocardiography at 48 to 96 hours. CONCLUSIONS BROKEN-SWEDEHEART will be the first prospective randomized multicenter trial in patients with TS. It is designed as 2 parallel studies to evaluate whether adenosine accelerates cardiac recovery and improves cardiac function in the acute phase and the efficacy of anticoagulation therapy for preventing thromboembolic complications in TS. If either of its component studies is successful, the trial will provide the first evidence-based treatment recommendation in TS. CLINICAL TRIALS IDENTIFIER The trial has been approved by the Swedish Medicinal Product Agency and the Swedish Ethical Board and is registered at ClinicalTrials.gov (NCT04666454).

Abstract
AIMS To provide data guiding long-term antithrombotic therapy after coronary artery by-pass grafting (CABG) in patients with preoperative atrial fibrillation (AF). METHODS AND RESULTS From the SWEDEHEART registry, we included all patients, between January 2006 and September 2016, with preoperative AF and CHA2DS2-VASC score ≥2, undergoing CABG. Based on dispensed prescriptions 12 to 18 months after CABG, patients were divided in 3 groups: use of platelet inhibitors (PI) only, oral anticoagulant (OAC) only or a combination of OAC + PI. Outcomes were: Major adverse cardiac and cerebrovascular events (MACCE, [all-cause death, myocardial infarction, or stroke]), net adverse clinical events (NACE, [MACCE or bleeding]) and the individual components of NACE. Inverse probability of treatment weighting was used to adjust for the non-randomized study design. Among 2,564 patients, 1,040 (41%) were treated with PI alone, 1,064 (41%) with OAC alone, and 460 (18%) with PI + OAC. Treatment with PI alone was associated with higher risk for MACCE (adjusted HR 1.43, 95% CI 1.09-1.88), driven by higher risk for stroke and MI, compared with OAC alone. Treatment with PI + OAC, was associated with higher risk for NACE (adjusted HR 1.40, 95% CI 1.06-1.85), driven by higher risk for bleeds, compared with OAC alone. CONCLUSION In this real-world observational study, a high proportion of patients with AF, undergoing CABG, did not receive a long-term OAC therapy. Treatment with OAC alone was associated with a net clinical benefit, compared with PI alone or PI + OAC.

Abstract
Background Frail older adults experience higher rates of adverse health outcomes. Therefore, assessing pre-hospital frailty early in the course of care is essential to identify the most vulnerable patients and determine their risk of deterioration. The Clinical Frailty Scale (CFS) is a frailty assessment tool that evaluates pre-hospital mobility, energy, physical activity, and function to generate a score that ranges from very fit to terminally ill. Purpose To synthesize the evidence of the association between the CFS degree and all-cause mortality, all-cause readmission, length of hospital stay, adverse discharge destination, and functional decline in patients >65 years in acute clinical settings. Design Systematic review with narrative synthesis. Methods Electronic databases (PubMed, EMBASE, CINAHL, Scopus) were searched for prospective or retrospective studies reporting a relationship between pre-hospital frailty according to the CFS and the outcomes of interest from database inception to April 2020. Results Our search yielded 756 articles, of which 29 studies were included in this review (15 were at moderate risk and 14 at low risk of bias). The included studies represented 26 cohorts from 25 countries (N = 44166) published between 2011 and 2020. All included studies showed that pre-hospital frailty according to the CFS is an independent predictor of all adverse health outcomes included in the review. Conclusion A primary purpose of the CFS is to grade clinically increased risk (i.e. risk stratification). Our results report the accumulated knowledge on the risk-predictive performance of the CFS and highlight the importance of routinely including frailty assessments, such as the CFS, to estimate biological age, improve risk assessments, and assist clinical decision-making in older adults in acute care. Further research into the potential of the CFS and whether implementing the CFS in routine practice will improve care and patients' quality of life is warranted.

Abstract
AIMS The aim was to describe the prevalence, characteristics, and outcome of patients with acute myocardial infarction (MI) developing left ventricular (LV) systolic dysfunction or pulmonary congestion by applying different criteria to define the population. METHODS AND RESULTS In patients with MI included in the Swedish web-system for enhancement and development of evidence-based care in heart disease (SWEDEHEART) registry, four different sets of criteria were applied, creating four not mutually exclusive subsets of patients: patients with MI and ejection fraction (EF) < 50% and/or pulmonary congestion (subset 1); EF < 40% and/or pulmonary congestion (subset 2); EF < 40% and/or pulmonary congestion and at least one high-risk feature (subset 3, PARADISE-MI like); and EF < 50% and no diabetes mellitus (subset 4, DAPA-MI like). Subsets 1, 2, 3, and 4 constituted 31.6%, 15.0%, 12.8%, and 22.8% of all patients with MI (n = 87 177), respectively. The age and prevalence of different co-morbidities varied between subsets. For median age, 70 to 77, for diabetes mellitus, 22 to 33%; for chronic kidney disease, 22 to 38%, for prior MI, 17 to 21%, for atrial fibrillation, 7 to 14%, and for ST-elevations, 38 to 50%. The cumulative incidence of death or heart failure hospitalization at 3 years was 17.4% (95% CI: 17.1-17.7%) in all MIs; 26.9% (26.3-27.4%) in subset 1; 37.6% (36.7-38.5%) in subset 2; 41.8% (40.7-42.8%) in subset 3; and 22.6% (22.0-23.2%) in subset 4. CONCLUSIONS Depending on the definition, LV systolic dysfunction or pulmonary congestion is present in 13-32% of all patients with MI and is associated with a two to three times higher risk of subsequent death or HF admission. There is a need to optimize management and improve outcomes for this high-risk population.

Abstract
AIM To examine sex differences in the characteristics and outcomes in participants with type 2 diabetes (T2D), with or without cardiovascular disease (CVD), randomized to once-weekly exenatide (EQW) or placebo in the Exenatide Study of Cardiovascular Event Lowering (EXSCEL). MATERIALS AND METHODS Baseline characteristics were summarized and compared by sex. Cox proportional hazards regression models were used for clinical outcomes, including the primary composite outcome of cardiovascular (CV) death, non-fatal myocardial infarction or non-fatal stroke (MACE3). Models including sex-by-treatment interaction were used to evaluate differences in effects of EQW. RESULTS Overall, 5603 women and 9149 men were followed for a median of 3.2 years. Women were younger (mean 61.4 vs. 62.2 years, P < .001) and had a shorter duration of diabetes (mean 12.9 vs. 13.2 years, P = .039) and less coronary artery disease (35.2% vs. 61.0%, P < .001) than men, but also a less favourable metabolic risk profile and lower use of cardioprotective medications. MACE3 occurred in 9.1% of women and 13.5% of men, corresponding to 2.82 versus 4.40 events/100 participant-years (adjusted hazard ratio 0.80, 95% CI: 0.70-0.93, P = .003). There was no difference in MACE3 with EQW compared with placebo, or evidence of heterogeneity of treatment effect by sex. CONCLUSIONS This analysis of a large population of individuals with T2D, with or without established CVD, identified between-sex differences in clinical characteristics and care. Despite having worse management of CV risk factors, women had significantly lower rates of important CV events not attributable to the effects of study treatment.

Abstract
AIMS Most trials showing benefit of beta-blocker treatment after myocardial infarction (MI) included patients with large MIs and are from an era before modern biomarker-based MI diagnosis and reperfusion treatment. The aim of the randomized evaluation of decreased usage of beta-blockers after acute myocardial infarction (REDUCE-AMI) trial is to determine whether long-term oral beta-blockade in patients with an acute MI and preserved left ventricular ejection fraction (EF) reduces the composite endpoint of death of any cause or recurrent MI. METHODS AND RESULTS It is a registry-based, randomized, parallel, open-label, multicentre trial performed at 38 centres in Sweden, 1 centre in Estonia, and 6 centres in New Zealand. About 5000 patients with an acute MI who have undergone coronary angiography and with EF ≥ 50% will be randomized to long-term treatment with beta-blockade or not. The primary endpoint is the composite endpoint of death of any cause or new non-fatal MI. There are several secondary endpoints, including all-cause death, cardiovascular death, new MI, readmission because of heart failure and atrial fibrillation, symptoms, functional status, and health-related quality of life after 6-10 weeks and after 1 year of treatment. Safety endpoints are bradycardia, AV-block II-III, hypotension, syncope or need for pacemaker, asthma or chronic obstructive pulmonary disease, and stroke. CONCLUSION The results from REDUCE-AMI will add important evidence regarding the effect of beta-blockers in patients with MI and preserved EF and may change guidelines and clinical practice.

Abstract
OBJECTIVES Our aim was to derive, based on the SWEDEHEART registry, and validate, using the Western Denmark Heart registry, a patient-oriented risk score, the SweDen score, which could calculate the risk of 1-year mortality following a myocardial infarction (MI). METHODS The factors included in the SweDen score were age, sex, smoking, diabetes, heart failure and statin use. These were chosen a priori by the SWEDEHEART steering group based on the premise that the factors were information known by the patients themselves. The score was evaluated using various statistical methods such as time-dependent receiver operating characteristics curves of the linear predictor, area under the curve metrics, Kaplan-Meier survivor curves and the calibration slope. RESULTS The area under the curve values were 0.81 in the derivation data and 0.76 in the validation data. The Kaplan-Meier curves showed similar patient profiles across datasets. The calibration slope was 1.03 (95% CI 0.99 to 1.08) in the validation data using the linear predictor from the derivation data. CONCLUSIONS The SweDen risk score is a novel tool created for patient use. The risk score calculator will be available online and presents mortality risk on a colour scale to simplify interpretation and to avoid exact life span expectancies. It provides a validated patient-oriented risk score predicting the risk of death within 1 year after suffering an MI, which visualises the benefit of statin use and smoking cessation in a simple way.

Abstract
INTRODUCTION Potential benefit with potent platelet inhibition in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI) has been discussed. The aim of this study was to compare a potent P2Y12 inhibition strategy using ticagrelor with clopidogrel in CCS patients referred for coronary angiography (CA) and PCI if feasible. METHODS In this retrospective real-world study, patients referred for outpatient CA due to suspected CCS were included. To adjust for group differences, a propensity score reflecting the probability of being treated with ticagrelor was calculated and added to the logistic regression outcome model. RESULTS In total, 1,003 patients were included in the primary analysis (577 treated with clopidogrel and 426 with ticagrelor). Among clopidogrel-treated patients, 132 (22.9%) experienced a bleeding complication compared with 93 (21.8%) among ticagrelor-treated patients, with no significant difference between the groups (p = 0.70). There was no difference in bleeding severity. Furthermore, we observed no statistically significant difference in major adverse cardiovascular events (MACE [death, stent thrombosis, myocardial infarction, or stroke]) (1.2% vs. 2.3%, p = 0.17). A subgroup analysis restricted to patients undergoing PCI ad hoc displayed a similar pattern. Also, patients undergoing CA without PCI ad hoc frequently experienced a bleeding complication, with no difference between the two treatments (21.0% vs. 17.3%, p = 0.27). Propensity score adjusted analyses confirmed the results. DISCUSSION In patients with CCS referred for CA and PCI if feasible, a more potent P2Y12 inhibition strategy with ticagrelor was not associated with bleeding complications or MACE compared with clopidogrel.

Abstract
The term frailty denotes a multi-dimensional syndrome characterised by reduced physiological reserves and increased vulnerability. Frailty may be used as a marker of biological age, distinct from chronological age. There are several instruments for frailty assessment. The Clinical Frailty Scale (CFS) is probably the most commonly used in the acute care context. It is a 9-level scale, derived from the accumulated deficit model of frailty, which combines comorbidity, disability, and cognitive impairment. The CFS assessment is fast and easy to implement in daily clinical practice. The CFS is relevant for risk stratification, and may also be used as a screening instrument to identify frail patients suitable for further geriatric evaluation, i.e. a comprehensive geriatric assessment (CGA). By providing information on long-term prognosis, it may improve informed decision-making on an individual basis.

Abstract
Abstract
Background
Despite abundant knowledge about the relationship between inflammation and coronary artery disease (CAD), it is still unknown whether high sensitivity C-reactive protein (hsCRP) is associated with coronary atherosclerosis in the general population.
Objectives
The project aimed to study the association between systemic inflammation, measured as hsCRP, and coronary artery atherosclerosis in a large population based cohort.
Methods
30,154 randomly selected men and women aged between 50 and 64 years were included in the SCAPIS (Swedish Cardiopulmonary Bioimage Study). After excluding those not undergoing coronary computed tomography angiography (CCTA), those with proximal segments not technically assessable and those with missing values of hsCRP, 25,408 individuals were analysed. Coronary artery atherosclerosis was defined as presence of plaque of any degree (1–49% or ≥50% diameter stenosis) or segments not assessable due to calcification in any of the 18 coronary segments. Analysis of severe atherosclerosis included participants with ≥50% diameter stenosis in any of the left main coronary artery (LMCA), the proximal left anterior descending artery (LAD) or three vessel disease including ≥50% diameter stenosis in any of the segments in each of the LAD, right coronary artery (RCA) and circumflex artery (CX). Participants with hsCRP above the lowest detection limit (≥0.7mg/L) were divided into tertiles and compared with hsCRP<0.7 mg/L as a reference.
Results
The highest tertile of measurable hsCRP (≥2.3 mg/L) was associated with coronary atherosclerosis in a multivariate analysis adjusted for classical cardiovascular risk factors (Table 1). HsCRP was also related to atherosclerosis with significant coronary artery diameter stenosis ≥50%, ≥4 segments involved, severe atherosclerosis and atherosclerosis with noncalcified plaques. Also, moderately elevated hsCRP (1.2–2.2 mg/L) was significant associated with noncalcified plaques. In a stratified analysis, coronary atherosclerosis was associated with the two highest tertiles of hsCRP (≥1.2 mg/L) in women, but not in men.
Conclusion
Elevated hsCRP was associated with the prevalence of coronary atherosclerosis in a population based cohort of middle-aged men and women. The relationships were more pronounced for atherosclerosis with noncalcified plaques and in women compared to men. This suggests that more attention should be given to hsCRP in risk assessment in middle-aged individuals without known disease, especially in women.

Abstract
Abstract
Background
Beta-blockers (BB) is an established treatment following presentation with myocardial infarction (MI). However, there is uncertainty as to whether BB use beyond the first year of MI has a secondary preventive role in patients without heart failure and/or left ventricular systolic dysfunction (LVSD).
Purpose
To investigate the association between BB treatment beyond one year after MI for patients without heart failure or LVSD and cardiovascular (CV) outcomes.
Methods
We used data from SWEDEHEART, the national Swedish register for coronary heart disease, to identify patients with MI who were hospitalised between 2005 and 2016. Deterministic linkage of individual patient data was performed with the National Patient Register, the Swedish Prescribed Drug Register, and the National Cause of Death Register. Patients with heart failure or LVSD with left ventricular ejection fraction <50% were excluded. Follow-up started at 1 year after hospitalisation with first MI (index date), when patients were allocated into two groups according to BB treatment. Information about BB treatment at index date and during follow-up was obtained from the Swedish National Prescribed Drug Register. The primary outcome was a composite of all-cause mortality, recurrent MI, unscheduled revascularisation or hospitalisation for heart failure. Secondary outcomes comprised the individual components of the composite outcome, CV death and stroke. Comparison of outcomes between the study groups was performed using Cox and Fine-Gray regression models adjusting for relevant clinical factors after propensity-score weighting. In the main intention-to-treat analysis, patients were censored at end of follow-up (31st December 2017), death or at pre-specified outcome, whichever came first. In supplementary per-protocol analysis, patients were, in addition, censored at the time of first BB discontinuation or switch between treatment arms.
Results
A total of 43,618 patients with MI were hospitalised between 2005 and 2016. Of these, 34,253 (78.5%) were prescribed BB and 9,365 (21.5%) were not on BB treatment at index date 1 year following MI. The median age of the population was 64 years, 25.5% were female, and 36.2% had a STEMI. Median follow-up was 4.5 years. In the intention-to-treat analysis, and after multivariable adjustments and propensity score weighting, BB treatment was associated with a similar rate of the composite CV outcome (hazard ratio [HR] 0.99; 95% confidence interval [CI] 0.93–1.04) compared with no BB treatment. A similar finding was observed when censoring for BB discontinuation or treatment switch during follow-up in a per-protocol analysis (HR 0.98; 95% CI 0.98–1.06). Similar associations were observed for all secondary outcomes (Figure 1).
Conclusions
BB treatment beyond one year after MI for patients without heart failure or LVSD is not associated with a different risk of cardiovascular outcomes compared with patients who do not receive BB.

Abstract
Abstract
Background
Remodeling of the extracellular matrix (ECM) plays a crucial role in development and progression of atherosclerosis. Collagens, in particular type I collagen, are the most abundant ECM proteins in an atherosclerotic plaque. Recently, type I collagen α1 chain (COL1α1) in plasma was identified as a potential predictor of coronary heart disease (CHD).
Aim
The aim was to further confirm the predictive value of COL1α1 and also to investigate its correlates in a population-based cohort as well as changes over time in patients with manifest CHD in Sweden.
Methods
In a total of 1007 well-characterized individuals (50% women), 86 CHD cases and 184 sex- and age-matched controls were identified at 13 years follow-up. CHD at follow-up was defined as first-time event of myocardial infarction (MI) or invasive coronary intervention. Plasma levels of COL1α1 was quantified by the Luminex assay while PRO-C1 and C1M, two markers of type I collagen synthesis and degradation, respectively, were quantified by ELISA. In Cox proportional hazard analysis, log2 values of biomarker levels were used. In addition, temporal change of COL1α1 levels was also examined in a cohort of 125 patients with acute MI followed for 6 months.
Results
COL1α1 levels were significantly associated with incident CHD, both unadjusted (HR = 0.69, 95% CI 0.56–0.87, p=0.001) and after multiple adjustment (HR = 0.55, 95% CI 0.41–0.75, p<0.001). PRO-C1 was similarly associated with CHD, unadjusted (HR = 0.62, 95% CI 0.47–0.82, p=0.001) as well as adjusted (HR = 0.61, 95% CI 0.43–0.86, p=0.005), while C1M was not. In patients with acute MI, COL1α1 levels remained stable over 6 months. COL1α1 was significantly correlated to PRO-C1 (r=0.73, p<0.001), while there were no correlations to C1M, markers of inflammation (C-reactive protein, interleukin-6, matrix metalloproteinase-9) or myocardial injury (troponin T).
Conclusions
Circulating COL1α1 in plasma was independently and inversely associated with incident CHD. Furthermore, COL1α1 levels appeared to be relatively stable after an acute MI. COL1α1 levels seem to reflect collagen synthesis rather than collagen degradation and inflammation. Future studies are needed to confirm whether COL1α1 is a clinically useful marker and/or predictor of CHD.

Abstract
Background The SWEDEHEART quality index of hospitals' adherence to the evidence-based (EB) guidelines for myocardial infarction (MI) patients has been continuously used for several decades in Sweden. The grading protocol is based on the consensus among hospitals. The hospitals are awarded points (0, 0.5, 1) for each of the 11 indicators depending on the proportion of patients who received EB treatment and achieved treatment goals. The 11 indicators at present are reperfusion treatment in STEMI (yes/no), time to-reperfusion treatment in STEMI, time to revascularisation in NSTEMI, P2Y12 antagonists at discharge, ACE-inhibitor/ARB at discharge, the proportion of patients at follow-up, smoking cessation at one-year, participation in a physical exercise program, target LDL-cholesterol and target blood pressure at one year. Purpose To evaluate whether the SWEDEHEART quality index predicts mortality in patients with MI. Methods We used data for all MI patients reported to the SWEDEHEART registry from 72 hospitals in Sweden between 2015–2021. We calculated the difference in quality index between 2021 and 2015. The hospitals were divided into quintiles based on the difference in the score. Logistic regression with log-time offset was used to adjust for confounders (age, gender, diabetes, hypertension, hyperlipidemia, STEMI/NSTEMI, cardiac arrest before admission, occupation status, history of heart failure, prior MI, prior PCI, prior CABG, cardiogenic shock). Results We identified 98,635 patients with MI, 32,608 (33.1%) were women and 34,198 (34.7%) had STEMI. The average age was 70.8±12.2 years. The median follow-up time was 2.7 years (IQR 1.06–4.63). The crude all-cause mortality rate was 5.5% at 30-days and 22.3% after long-term follow-up. Most hospitals (72.1%) improved their quality index on average by 3.4% per year (P<0.001). The increase in the quality index continued during COVID-19 pandemic (2020–2021) with average increase of 8.6%, 95% CI, 0.97–1.02; P<0.001. The median change in SWEDEHEART quality index score among the quintiles were −1.5 (Q1), 0,5 (Q2), 2,5 (Q3), 3 (Q4), and 4 (Q5). We found no difference in mortality between the quintiles at 30-days (OR 0.99; 95% CI 0.97–1.02; p=1.02) and long-term (OR 1.01; 95% CI 0,99–1.02; p=0.850). Conclusion The SWEDEHEART quality index provides valuable descriptive information about hospitals' adherence to the guidelines. However, the index, in its current form, does not predict mortality in patients with MI. Funding Acknowledgement Type of funding sources: None.

Abstract
Abstract
Background/Introduction
Duration and intensity of antithrombotic treatment after myocardial infarction should be individualized based on a patient's ischemic and bleeding risk [1,2]. While such strategies are typically based on calculations that give equal weight to both types of events, uncertainty remains regarding their relative importance.
Purpose
To describe the incidence of ischemic and bleeding events in patients with a recent myocardial infarction, to compare the association of an ischemic vs bleeding event with mortality and to assess whether this association had changed over the past two decades.
Methods
Patients with acute myocardial infarction enrolled in the SWEDEHEART registry and discharged alive with antithrombotic treatment (aspirin, P2Y12 inhibitor, or oral anticoagulant) from January 2012 to December 2017 were followed from discharge until an ischemic event (recurrent myocardial infarction or ischemic stroke) or bleeding event. Cox regression adjusted for demographic factors, comedications and comorbidities, was used to estimate hazard ratios (HR) for time to death after an ischemic and bleeding event as compared with no event (in a model using time-varying exposure definition) and for an ischemic vs bleeding event in a direct comparison. We then assessed whether the adjusted HR for mortality of an ischemic vs bleeding event had changed across three time-periods (1997–2000, 2001–2011 and 2012–2017) by using an interaction term between time period and type of event.
Results
From January 2012 until December 2017 86, 736 patients were discharged alive with antithrombotic treatment after a myocardial infarction. Of these, 4,039 patients experienced a first ischemic event (incidence rate 5.7 events per 100 person-years), and 3,399 a first bleeding event (incidence rate 4.8 events per 100 person-years). As compared with no event, both ischemic events (adjusted HR 4.16, 95% CI 3.91 to 4.43) and bleeding events (adjusted HR 3.43, 95% CI 3.17 to 3.71) were associated with an increased risk of death. In the direct comparison, ischemic events were associated with a higher risk of death than bleeding events (adjusted HR 1.27, 95% CI 1.15 to 1.40). There was no evidence of a change in the aHR across the three time periods (aHR; 1.17, 95% CI 1.02 to 1.35 in 1997–2000 and 1.18, 95% CI, 1.11 to 1.27 in 2001–2011, p for interaction between time period and type of event ≥0.646).
Conclusion
In this nationwide study of patients with a recent MI, post-discharge ischemic events were more common and associated with higher mortality risk as compared with bleeding events.

Abstract
Abstract
Background
Previous studies have demonstrated that total ischaemic time during ST-elevation myocardial Infarction (STEMI) is associated with mortality. However, how duration from symptom onset to hospital admission affects outcomes and how pre-hospital delay times (PHDT) have evolved over time in STEMI in total, as well as in prespecified subgroups, remains unknown.
Aim
The aim was to explore temporal trends and prognostic impact of PHDT in STEMI patients during the last two decades in Sweden, including the fibrinolytic era as well as the primary percutaneous coronary intervention (PPCI) era. Temporal trends of PHDT was aimed to be studied in the total STEMI cohort as well as in subgroups according to age, sex and presence or absence of diabetes.
Method
This was an observational retrospective cohort study based on the SWEDEHEART registry including 89,155 STEMI patients between 1998 and 2017.
Results
In total, the PHDT curve was hump-shaped without any significant trend. The median PHDT was 150 min (Q1 80; Q3 302), and the shortest PHDT of 140 (Q1 85; Q3 274) min was found during the last period. During the fibrinolytic era (1998–2004) there was a significant increase in PHDT while delay times decreased during the PPCI era (2005–2017). There were consistent differences within subgroups; women sought care 25 min later than men, older (>70 years) delayed 30 min longer than younger and patients with diabetes 29 min longer than those without. Higher short- and long-term mortality was seen with increasing delay except for the group seeking care within 1 hour, which had higher short-term mortality. In five years follow up, mortality incrementally increased with delay, from 24.1% (0–1 hours) to 31.1% (>12 hours) of PHDT, p<0.01. When adjusting for confounders the risk of dying within 1 and 5 years was approximately 1% per hour of increase of PHDT (HR 1.011, 95% CI 1.006–1.016 and HR 1.008, 95% CI 1.004–1.013, respectively).
Conclusions
PHDT is an independent predictor of short- and long-term mortality and reducing PHDT will diminish the risk of heart failure and premature death. We found only a modest decrease in PHDT over time and the trend was hump shaped. Since the implementation of PPCI, with the diagnosis of STEMI made in the ambulances, these have been redirected in the pre-hospital setting, transporting the patient directly to cath lab. This may explain why the PHDT initially increased in the beginning of this era when new routines were being established. Although we did not find any significant trend during the total 20-year period it is reassuring that the PHDT decreased during the PPCI era. Anyhow, there are subgroups with consistently prolonged PHDT, such as women, the elderly, and patients with diabetes, who need to be targeted in future interventions.

Abstract
Abstract
Background
Potent antiplatelet agents such as ticagrelor are associated with a lower risk of ischemic events than clopidogrel in patients with acute coronary syndrome (ACS). However, it is uncertain whether the benefits of more intensive anti-ischemic therapy outweigh the risks of major bleeding in individuals who have a high bleeding risk (HBR). This study aimed to assess treatment outcomes following dual antiplatelet therapy (DAPT) using either ticagrelor or clopidogrel in ACS patients with HBR.
Methods
All HBR patients enrolled in the SWEDEHEART registry who were discharged with DAPT using ticagrelor or clopidogrel following ACS between 2010 and 2017 were included in this study. Bleeding risk was assessed using the 4-item PRECISE-DAPT score, which consists of age, prior bleeding, haemoglobin concentration and creatinine clearance. HBR was defined as a PRECISE-DAPT score ≥25. Inverse-probability of treatment weighting was used to adjust for baseline differences between the treatment groups. The main analysis consisted of a doubly robust estimation of causal effect using Cox proportional hazards models. Data on major bleeding, recurrent myocardial infarction (MI), ischemic stroke and all-cause mortality was obtained from national registries, with 365 days of follow-up. Additional outcomes include major adverse cardiovascular events (MACE), a composite of MI, ischemic stroke and all-cause mortality, and net adverse clinical events (NACE), a composite of MACE and major bleeding.
Results
Of all ACS patients, 36% (n=25,042) had a PRECISE-DAPT score ≥25. Approximately half of the study participants were treated with ticagrelor (n=11,848). Ticagrelor reduced the risk of MI (hazard ratio [HR], 0.82 [95% CI 0.74–0.91]), ischemic stroke (HR, 0.73 [95% CI 0.60–0.88]) and MACE (HR, 0.90 [95% CI 0.84–0.97]), while also increasing the risk of major bleeding compared to clopidogrel (HR, 1.30 [95% CI 1.16–1.47]). We found no significant differences in all-cause mortality (HR 1.02 [95% CI 0.92–1.12]) and NACE (HR 0.98 [95% CI 0.92–1.05]).
Conclusions
Ticagrelor was associated with a lower risk of recurrent ischemic events, but a higher risk of major bleeding compared to clopidogrel. There were no significant differences in all-cause mortality and NACE between the treatment groups. These results suggest that more potent antiplatelet agents might not be superior to clopidogrel in ACS patients with HBR.

Abstract
Objective Postoperative atrial fibrillation (POAF) is a common complication affecting approximately one-third of patients after cardiac surgery and valvular interventions. This umbrella review systematically appraises the epidemiological credibility of published meta-analyses of both observational and randomised controlled trials (RCT) to assess the risk and protective factors of POAF. Methods Three databases were searched up to June 2021. According to established criteria, evidence of association was rated as convincing, highly suggestive, suggestive, weak or not significant concerning observational studies and as high, moderate, low or very low regarding RCTs. Results We identified 47 studies (reporting 61 associations), 13 referring to observational studies and 34 to RCTs. Only the transfemoral transcatheter aortic valve replacement (TAVR) approach was associated with the prevention of POAF and was supported by convincing evidence from meta-analyses of observational data. Two other associations provided highly suggestive evidence, including preoperative hypertension and neutrophil/lymphocyte ratio. Three associations between protective factors and POAF presented a high level of evidence in meta-analyses, including RCTs. These associations included atrial and biatrial pacing and performing a posterior pericardiotomy. Nineteen associations were supported by moderate evidence, including use of drugs such as amiodarone, b-blockers, glucocorticoids and statins and the performance of TAVR compared with surgical aortic valve replacement. Conclusions Our study provides evidence confirming the protective role of amiodarone, b-blockers, atrial pacing and posterior pericardiotomy against POAF as well as highlights the risk of untreated hypertension. Further research is needed to assess the potential role of statins, glucocorticoids and colchicine in the prevention of POAF. PROSPERO registration number CRD42021268268.

Abstract
Background A significant proportion of patients with ST-segment-elevation myocardial infarction (MI) have no standard modifiable cardiovascular risk factors (SMuRFs) and have unexpected worse 30-day outcomes compared with those with SMuRFs. The aim of this article is to examine outcomes of patients with non-ST-segment-elevation MI in the absence of SMuRFs. Methods and Results Presenting features, management, and outcomes of patients with non-ST-segment-elevation MI without SmuRFs (hypertension, diabetes, hypercholesterolemia, smoking) were compared with those with SmuRFs in the Swedish MI registry SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies; 2005-2018). Cox proportional hazard models were used. Out of 99 718 patients with non-ST-segment-elevation MI, 11 131 (11.2%) had no SMuRFs. Patients without SMuRFs had higher all-cause and cardiovascular mortality at 30 days (hazard ratio [HR], 1.20 [95% CI, 1.10-1.30], P<0.0001; and HR, 1.25 [95% CI, 1.13-1.38]), a difference that remained after adjustment for age and sex. SMuRF-less patients were less likely to receive secondary prevention statins (76% versus 82%); angiotensin-converting enzyme inhibitors/angiotensin receptor blockade (54% versus 72%); or β-blockers (81% versus 87%, P for all <0.0001), with lowest rates observed in women without SMuRFs. In patients who survived to 30 days, rates of all-cause and cardiovascular death were lower in patients without SMuRFs compared with those with risk factors, over 12 years. Conclusions One in 10 patients presenting with non-ST-segment-elevation MI present without traditional risk factors. The excess 30-day mortality rate in this group emphasizes the need for both improved population-based strategies for prevention of MI, as well as the need for equitable evidence-based treatment at the time of an MI.

Abstract
IMPORTANCE Antithrombotic treatment after myocardial infarction (MI) should be individualized based on the patient's risk of ischemic and bleeding events. Uncertainty remains regarding the relative prognostic importance of the 2 types of events, and further study would be useful. OBJECTIVES To compare the association of ischemic vs bleeding events with mortality in patients with a recent MI and assess whether the relative mortality risk for the 2 types of events has changed over the past 2 decades. DESIGN, SETTING, AND PARTICIPANTS A cohort study based on nationwide registers in Sweden, 2012-2017, was conducted. Data were analyzed between July 2021 and May 2022. Patients with MI who were discharged alive with antithrombotic therapy (antiplatelet therapy or oral anticoagulation) were included in the analysis. MAIN OUTCOMES AND MEASURES The incidence of a first ischemic event (hospitalization for MI or ischemic stroke) or bleeding event (hospitalization with bleeding) up to 1 year after discharge and the mortality risk up to 1 year after each type of event were assessed. Cox proportional hazards regression models were used to estimate adjusted hazard ratios (aHRs) for 1-year mortality after an ischemic and bleeding event vs no event, and after an ischemic vs bleeding event. Adjusted HRs for mortality after ischemic vs bleeding events were compared among patients discharged in 1997-2000, 2001-2011, and 2012-2017. RESULTS Of 86 736 patients discharged after MI in 2012-2017 (median age, 71 [IQR, 62-80] years; 57 287 [66.0%] men), 4039 individuals experienced a first ischemic event (5.7 per 100 person-years) and 3399 experienced a first bleeding event (4.8 per 100 person-years). The mortality rate was 46.2 per 100 person-years after an ischemic event and 27.1 per 100 person-years after a bleeding event. The aHR for 1-year mortality vs no event was 4.16 (95% CI, 3.91-4.43) after an ischemic event and 3.43 (95% CI, 3.17-3.71) after a bleeding event. When the 2 types of events were compared, the aHR was 1.27 (95% CI, 1.15-1.40) for an ischemic vs bleeding event. There was no statistically significant difference in the aHR of an ischemic vs bleeding event in 1997-2000, 2001-2011, and 2012-2017. CONCLUSIONS AND RELEVANCE In this nationwide cohort study of patients with a recent MI, postdischarge ischemic events were more common and associated with higher mortality risk compared with bleeding events.

Abstract
Background Myocardial infarction (MI) is a major cause of heart failure. Left ventricular adverse remodeling is common post-MI. Several studies have demonstrated a correlation between reduced myocardial strain and the development of adverse remodeling. Cardiac magnetic resonance (CMR) with fast-strain encoding (fast-SENC) or feature tracking (FT) enables rapid assessment of myocardial deformation. The aim of this study was to establish a head-to-head comparison of fast-SENC and FT in post-ST-elevated myocardial infarction (STEMI) patients, with clinical 2D speckle tracking echocardiography (2DEcho) as a reference. Methods Thirty patients treated with primary percutaneous coronary intervention for STEMI were investigated. All participants underwent CMR examination with late gadolinium enhancement, cine-loop steady-state free precession, and fast-SENC imaging using a 1.5T scanner as well as a 2DEcho. Global longitudinal strain (GLS), segmental longitudinal strain (SLS), global circumferential strain (GCS), and segmental circumferential strain (SCS) were assessed along with the MI scar extent. Results The GCS measurements from fast-SENC and FT were nearly identical: the mean difference was 0.01 (2.5)% (95% CI - 0.92 to 0.95). For GLS, fast-SENC values were higher than FT, with a mean difference of 1.8 (1.4)% (95% CI 1.31-2.35). Tests of significance for GLS did not show any differences between the MR methods and 2DEcho. Average strain in the infarct-related artery (IRA) segments compared to the remote myocardium was significantly lower for the left anterior descending artery and right coronary artery culprits but not for the left circumflex artery culprits. Fast-SENC displayed a higher area under the curve for detecting infarcted segments than FT for both SCS and SLS. Conclusion GLS and GCS did not significantly differ between fast-SENC and FT. Both showed acceptable agreement with 2DEcho for longitudinal strain. Segments perfused by the IRA showed significantly reduced strain values compared to the remote myocardium. Fast-SENC presented a higher sensitivity and specificity for detecting infarcted segments than FT.

Abstract
Background: Myocardial infarction (MI) occurs frequently and requires considerable health care resources. It is important to ensure that the treatments which are provided are both clinically effective and economically justifiable. Based on recent new evidence, routine oxygen therapy is no longer recommended in MI patients without hypoxemia. By using data from a nationwide randomized clinical trial, we estimated oxygen therapy related cost savings in this important clinical setting. Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction (DETO2X-AMI) trial randomized 6,629 patients from 35 hospitals across Sweden to oxygen at 6 L/min for 6–12 h or ambient air. Costs for drug and medical supplies, and labor were calculated per patient, for the whole study population, and for the total annual care episodes for MI in Sweden (N = 16,100) with 10 million inhabitants. Results: Per patient, costs were estimated to 36 USD, summing up to a total cost of 119,832 USD for the whole study population allocated to oxygen treatment. Applied to the annual care episodes for MI in Sweden, costs sum up to between 514,060 and 604,777 USD. In the trial, 62 (2%) patients assigned to oxygen and 254 (8%) patients assigned to ambient air developed hypoxemia. A threshold analysis suggested that up to a cut-off of 624 USD spent for hypoxemia treatment related costs per patient, avoiding routine oxygen therapy remains cost saving. Conclusions: Avoiding routine oxygen therapy in patients with suspected or confirmed MI without hypoxemia at baseline saves significant expenditure for the health care system both with regards to medical and human resources.

Abstract
AIMS Ischaemic coronary artery disease (CAD) remains the leading cause of mortality globally due to sudden death and heart failure (HF). Invasive coronary angiography (CAG) is the gold standard for evaluating the presence and severity of CAD. Our objective was to assess temporal trends in CAG utilization, patient characteristics, and prognosis in HF patients undergoing CAG at a national level. METHODS AND RESULTS We used data from the Swedish Coronary Angiography and Angioplasty Registry. Data on all patients undergoing CAG for HF indication in Sweden between 2000 and 2018 were collected and analysed. Long-term survival was estimated with multivariable Cox proportional hazards regression adjusted for differences in patient characteristics. In total, 22 457 patients (73% men) with mean age 64.2 ± 11.3 years were included in the study. The patients were increasingly older with more comorbidities over time. The number of CAG specifically for HF indication increased by 5.5% per calendar year (P < 0.001). No such increase was seen for indications angina pectoris and ST-elevation myocardial infarction. A normal CAG or non-obstructive CAD was reported in 63.2% (HF-NCAD), and 36.8% had >50% diameter stenosis in one or more coronary arteries (HF-CAD). The median follow-up time was 3.6 years in HF-CAD and 5 years in HF-NCAD. Age and sex-adjusted survival improved linearly by 1.3% per calendar year in all patients. Compared with HF-NCAD, long-term mortality was higher in HF-CAD patients. The risk of death increased with the increasing severity of CAD. Compared with HF-NCAD, the risk estimate in patients with a single-vessel disease was higher [hazard ratio (HR) 1.3; 95% confidence interval (CI) 1.20-1.41; P < 0.001], a multivessel disease without the involvement of left main coronary artery (HR 1.72; 95% CI 1.58-1.88; P < 0.001), and with left main disease (HR 2.02; 95% CI 1.88-2.18; P < 0.001). The number of HF patients undergoing revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) increased by 7.5% (P < 0.001) per calendar year. The majority (53.4%) of HF-CAD patients were treated medically, while a minority (46.6%) were referred for revascularization with PCI or CABG. Compared with patients treated with PCI, the proportion of patients treated medically or with CABG decreased substantially (P < 0.001). CONCLUSIONS Over 18 years, the number of patients with HF undergoing CAG has increased substantially. Expanded utilization of CAG increased the number of HF patients treated with percutaneous coronary intervention and coronary artery bypass surgery. Long-term survival improved in all HF patients despite a steady increase of elderly patients with comorbidities.

Abstract
Aims Data on the prognostic value of frailty to guide clinical decision-making for patients with myocardial infarction (MI) are scarce. To analyse the association between frailty classification, treatment patterns, in-hospital outcomes, and 6-month mortality in a large population of patients with MI. Methods and results An observational, multicentre study with a retrospective analysis of prospectively collected data using the SWEDEHEART registry. In total, 3381 MI patients with a level of frailty assessed using the Clinical Frailty Scale (CFS-9) were included. Of these patients, 2509 (74.2%) were classified as non-vulnerable non-frail (CFS 1–3), 446 (13.2%) were vulnerable non-frail (CFS 4), and 426 (12.6%) were frail (CFS 5–9). Frailty and non-frail vulnerability were associated with worse in-hospital outcomes compared with non-frailty, i.e. higher rates of mortality (13.4% vs. 4.0% vs. 1.8%), cardiogenic shock (4.7% vs. 2.5% vs. 1.9%), and major bleeding (4.5% vs. 2.7% vs. 1.1%) (all P < 0.001), and less frequent use of evidence-based therapies. In Cox regression analyses, frailty was strongly and independently associated with 6-month mortality compared with non-frailty, after adjustment for age, sex, the GRACE risk score components, and other potential risk factors [hazard ratio (HR) 3.32, 95% confidence interval (CI) 2.30–4.79]. A similar pattern was seen for vulnerable non-frail patients (fully adjusted HR 2.07, 95% CI 1.41–3.02). Conclusion Frailty assessed with the CFS was independently and strongly associated with all-cause 6-month mortality, also after comprehensive adjustment for baseline differences in other risk factors. Similarly, non-frail vulnerability was independently associated with higher mortality compared with those with preserved functional ability.

Abstract
Studies of platelet function in surgical patients often involve both arterial and venous sampling. Possible effects of different sampling sites could be important, but have not been thoroughly investigated. We aimed to compare platelet function in arterial and venous blood samples using a novel flow cytometry protocol and impedance aggregometry. Arterial and venous blood was collected before anesthesia in 10 patients undergoing cardiac surgery of which nine was treated with acetylsalicylic acid until the day before surgery. Flow cytometry included simultaneous analysis of phosphatidylserine exposure, active conformation of the fibrinogen receptor (PAC-1 binding), α-granule and lysosomal release (P-selectin and LAMP-1 exposure) and mitochondrial membrane integrity. Platelets were activated with ADP or peptides activating thrombin receptors (PAR1-AP/PAR4-AP) or collagen receptor GPVI (CRP-XL). Leukocyte-platelet conjugates and P-selectin exposure were evaluated immediately in fixated samples. For impedance aggregometry (Multiplate®), ADP, arachidonic acid, collagen and PAR1-AP (TRAP) were used as activators. Using impedance aggregometry and in 27 out of 37 parameters studied with flow cytometry there was no significant difference between venous and arterial blood sampling. Arterial blood showed more PAC-1 positive platelets when activated with PAR1-AP or PAR4-AP and venous blood showed more monocyte-platelet and neutrophil-platelet conjugates and higher phosphatidylserine exposure with CRP-XL alone and combined with PAR1-AP or PAR4-AP. We found no differences using impedance aggregometry. In conclusion, testing of platelet function by flow cytometry and impedance aggregometry gave comparable results for most of the studied parameters in venous and arterial samples. Flow cytometry identified differences in PAC-1 binding when activated with PAR1-AP, exposure of phosphatidyl serine and monocyte/neutrophil-platelet conjugates, which might reflect differences in blood sampling technique or in flow conditions in this patient cohort with coronary artery disease. These differences might be considered when comparing data from different sample sites, but caution should be exercised if a different protocol is used or another patient group is studied.

Abstract
Supplemental Digital Content is available in the text. Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population. Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data. Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population. Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

Abstract
BACKGROUND Characteristics and prognosis of patients admitted with strong suspicion of myocardial infarction (MI) but discharged without an MI diagnosis are not well-described. OBJECTIVES To compare background characteristics and cardiovascular outcomes in patients discharged with or without MI diagnosis. METHODS The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction (DETO2X-AMI) trial compared 6629 patients with strong suspicion of MI randomized to oxygen or ambient air. The main composite end-point of this subgroup analysis was the incidence of all-cause death, rehospitalization with MI, heart failure (HF) or stroke during a follow-up of 2.1 years (median; range: 1-3.7 years) irrespective of randomized treatment. RESULTS 1619 (24%) received a non-MI discharge diagnosis, and 5010 patients (76%) were diagnosed with MI. Groups were similar in age, but non-MI patients were more commonly female and had more comorbidities. At thirty days, the incidence of the composite end-point was 2.8% (45 of 1619) in non-MI patients, compared to 5.0% (250 of 5010) in MI patients with lower incidences in all individual end-points. However, for the long-term follow-up, the incidence of the composite end-point increased in the non-MI patients to 17.7% (286 of 1619) as compared to 16.0% (804 of 5010) in MI patients, mainly driven by a higher incidence of all-cause death, stroke and HF. CONCLUSIONS Patients admitted with a strong suspicion of MI but discharged with another diagnosis had more favourable outcomes in the short-term perspective, but from one year onwards, cardiovascular outcomes and death deteriorated to a worse long-term prognosis.

Abstract
BACKGROUND A method for improving the accuracy of coronary computed tomography angiography (CCTA) is highly sought after as it would help to avoid unnecessary invasive coronary angiographies. Measurement of the transluminal attenuation gradient (TAG) has been proposed as an alternative to other existing methods, i.e. CT perfusion and CT fractional flow reserve (FFR). PURPOSE To evaluate the incremental value of three types of TAG in high-pitch spiral CCTA with invasive FFR measurements as reference. MATERIAL AND METHODS TAG was measured using two semi-automatic methods and one manual method. A receiver operating characteristic (ROC) analysis was made to determine the usefulness of TAG alone as well as TAG combined with CCTA for detection of significant coronary artery stenoses defined by an invasive FFR value ≤0.80. RESULTS A total of 51 coronary vessels in 37 patients were included in this retrospective study. Hemodynamically significant stenoses were found in 13 vessels according to FFR. The ROC analysis TAG alone resulted in areas under the curve (AUCs) of 0.530 and 0.520 for the semi-automatic TAG and 0.557 for the manual TAG. TAG and CCTA combined resulted in AUCs of 0.567, 0.562 for semi-automatic TAG, and 0.569 for the manual TAG. CONCLUSION The results from our study showed no incremental value of TAG measured in single heartbeat CCTA in determining the severity of coronary artery stenosis degrees.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) affects 20-30% of the general adult population. NAFLD patients with type 2 diabetes mellitus (T2DM) are at an increased risk of advanced fibrosis, which puts them at risk of cardiovascular complications, hepatocellular carcinoma, or liver failure. Liver biopsy is the gold standard for assessing hepatic fibrosis. However, its utility is inherently limited. Consequently, the prevalence and characteristics of T2DM patients with advanced fibrosis are unknown. Therefore, the purpose of the current study is to evaluate the prevalence and severity of NAFLD in patients with T2DM by recruiting participants from primary care, using the latest imaging modalities, to collect a cohort of well phenotyped patients. METHODS We will prospectively recruit 400 patients with T2DM using biomarkers to assess their status. Specifically, we will evaluate liver fat content using magnetic resonance imaging (MRI); hepatic fibrosis using MR elastography and vibration-controlled transient elastography; muscle composition and body fat distribution using water-fat separated whole body MRI; and cardiac function, structure, and tissue characteristics, using cardiovascular MRI. DISCUSSION We expect that the study will uncover potential mechanisms of advanced hepatic fibrosis in NAFLD and T2DM and equip the clinician with better diagnostic tools for the care of T2DM patients with NAFLD.

Abstract
OBJECTIVES This study sought to compare interrupted and uninterrupted oral anticoagulant therapy (I-OAC vs. U-OAC) in patients on OAC undergoing percutaneous coronary intervention. BACKGROUND There is a paucity of data regarding the optimal peri-procedural management of OAC-treated patients. METHODS In the SWEDEHEART registry, all patients on OAC who were admitted acutely and underwent percutaneous coronary intervention or coronary angiography with a diagnostic procedure, from 2005 to 2017, were included. Outcomes were major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction, or stroke) and bleeds at 120 days. Propensity score was used to adjust for the nonrandomized treatment selection. RESULTS The study included 6,485 patients: 3,322 in the I-OAC group and 3,163 in the U-OAC group. The cumulative incidence of MACCE was 8.2% (269 events) versus 8.2% (254 events) in the I-OAC and the U-OAC groups, respectively. The adjusted risk for MACCE did not differ between the groups (I-OAC vs. U-OAC hazard ratio: 0.89; 95% confidence interval: 0.71 to 1.12). Similarly, no difference was found in the risk for MACCE or bleeds (12.6% vs. 12.9%, adjusted hazard ratio: 0.87; 95% confidence interval: 0.70 to 1.07). The risk for major or minor in-hospital bleeds did not differ between the groups. However, U-OAC was associated with a significantly shorter duration of hospitalization: 4 (3 to 7) days versus 5 (3 to 8) days; p < 0.01. CONCLUSIONS I-OAC and U-OAC were associated with equivalent risk for MACCE and bleeding complications. An U-OAC strategy was associated with shorter length of hospitalization. These data support U-OAC as the preferable strategy in patients on OAC undergoing coronary intervention.

Abstract
OBJECTIVES Bleeding is the most common non-ischemic complication in patients with coronary revascularisation procedures, associated with prolonged hospitalisation and increased mortality. Many factors predispose for bleeds in these patients, among those sex. Anyhow, few studies have characterised the population receiving triple antithrombotic therapy (TAT) as well as long term bleeds from a sex perspective. We investigated the one year rate of bleeds in patients receiving TAT, potential sex disparities and premature discontinuation of TAT. We also assessed health care costs in bleeders vs non-bleeders. SETTING Three hospitals in the County of Östergötland, Sweden during 2009-2015. PARTICIPANTS All patients discharged with TAT registered in the SWEDEHEART registry. PRIMARY AND SECONDARY OUTCOME MEASURES All bleeds receiving medical attention during one-year follow-up were collected by retrieving relevant information about each patient from medical records. Resource use associated with bleeds was assigned unit cost to estimate the health care costs associated with bleeding episodes. RESULTS Among 272 patients, 156 bleeds occurred post-discharge, of which 28.8% were gastrointestinal. In total 54.4% had at least one bleed during or after the index event and 40.1% bled post discharge of whom 28.7% experienced a TIMI major or minor bleeding. Women discontinued TAT prematurely more often than men (52.9 vs 36.1%, p = 0.01) and bled more (48.6 vs. 37.1%, p = 0.09). One-year mean health care costs were EUR 575 and EUR 5787 in non-bleeding and bleeding patients, respectively. CONCLUSION The high bleeding incidence in patients with TAT, especially in women, is a cause of concern. There is a need for an adequately sized randomised, controlled trial to determine a safe but still effective treatment for these patients.

Abstract
BACKGROUND In cardiovascular disease, prevention strategies targeting standard modifiable cardiovascular risk factors (SMuRFs; hypertension, diabetes, hypercholesterolaemia, and smoking) are crucial; however, myocardial infarction in the absence of SMuRFs is not infrequent. The outcomes of individuals without SMuRFs are not well known. METHODS We retrospectively analysed adult patients with first-presentation ST-elevation myocardial infarction (STEMI) using data from the Swedish myocardial infarction registry SWEDEHEART. Clinical characteristics and outcomes of adult patients (age ≥18 years) with and without SMuRFs were examined overall and by sex. Patients with a known history of coronary artery disease were excluded. The primary outcome was all-cause mortality at 30 days after STEMI presentation. Secondary outcomes included cardiovascular mortality, heart failure, and myocardial infarction at30 days. Endpoints were also examined up to discharge, and to the end of a 12-year follow-up. Multivariable logistic regression models were used to compare in-hospital mortality, and Cox-proportional hazard models and Kaplan-Meier analysis for long-term outcomes. FINDINGS Between Jan 1, 2005, and May 25, 2018, 9228 (14·9%) of 62 048 patients with STEMI had no SMuRFs reaching diagnostic thresholds. Median age was similar between patients with SMuRFs and patients without SMuRFs (68 years [IQR 59-78]) vs 69 years [60-78], p<0·0001). SMuRF-less patients had a similar rate of percutaneous coronary intervention to those with at least one modifiable risk factor, but were significantly less likely to receive statins, angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockade (ARB), or β-blockers at discharge. By 30 days after presentation, all-cause mortality was significantly higher in SMuRF-less patients (hazard ratio 1·47 [95% CI 1·37-1·57], p<0·0001). SMuRF-less women had the highest 30-day mortality (381 [17·6%] of 2164), followed by women with SMuRFs (2032 [11·1%] of 18 220), SMuRF-less men (660 [9·3%] of 7064), and men with SMuRFs (2117 [6·1%] of 34 600). The increased risk of 30-day all-cause mortality in SMuRF-less patients remained significant after adjusting for age, sex, left ventricular ejection fraction, creatinine, and blood pressure, but was attenuated on inclusion of pharmacotherapy prescription (ACEI or ARB, β-blocker, or statin) at discharge. Additionally, SMuRF-less patients had a significantly higher rate of in-hospital all-cause mortality than patients with one or more SMuRF (883 [9·6%] vs 3411 [6·5%], p<0·0001). Myocardial infarction and heart failure at 30 days were lower in SMuRF-less patients. All-cause mortality remained increased in the SMuRF-less group for more than 8 years in men and up to the 12-year endpoint in women. INTERPRETATION Individuals who present with STEMI in the absence of SMuRFs have a significantly increased risk of all-cause mortality, compared with those with at least one SMuRF, which was particularly evident in women. The increased early mortality rates are attenuated after adjustment for use of guideline-indicated treatments, highlighting the need for evidence-based pharmacotherapy during the immediate post-infarct period irrespective of perceived low risk.

Abstract
Background: After decades of ubiquitous oxygen therapy in all patients with acute myocardial infarction (MI), recent guidelines are more restrictive based on lack of efficacy in contemporary trials evaluating hard clinical outcomes in patients without hypoxemia at baseline. However, no evidence regarding treatment effects on health-related quality of life (HRQoL) exists. In this study, we investigated the impact of routine oxygen supplementation on HRQoL 6–8 weeks after hospitalization with acute MI. Secondary objectives included analyses of MI subtypes, further adjustment for infarct size, and oxygen saturation at baseline and 1-year follow-up. Methods: In the DETermination of the role of Oxygen in suspected Acute Myocardial Infarction (DETO2X-AMI) trial, 6,629 normoxemic patients with suspected MI were randomized to oxygen at 6 L/min for 6–12 h or ambient air. In this prespecified analysis, patients younger than 75 years of age with confirmed MI who had available HRQoL data by European Quality of Life Five Dimensions questionnaire (EQ-5D) in the national registry were included. Primary endpoint was the EQ-5D index assessed by multivariate linear regression at 6–10 weeks after MI occurrence. Results: A total of 3,086 patients (median age 64, 22% female) were eligible, 1,518 allocated to oxygen and 1,568 to ambient air. We found no statistically significant effect of oxygen therapy on EQ-5D index (−0.01; 95% CI: −0.03–0.01; p = 0.23) or EQ-VAS score (−0.57; 95% CI: −1.88–0.75; p = 0.40) compared to ambient air after 6–10 weeks. Furthermore, no significant difference was observed between the treatment groups in EQ-5D dimensions. Results remained consistent across MI subtypes and at 1-year follow-up, including further adjustment for infarct size or oxygen saturation at baseline. Conclusions: Routine oxygen therapy provided to normoxemic patients with acute MI did not improve HRQoL up to 1 year after MI occurrence.

Abstract
OBJECTIVE The comparative efficacy and safety of prasugrel and ticagrelor in patients with myocardial infarction (MI) treated with percutaneous coronary intervention (PCI) remain unclear. We aimed to investigate the association of treatment with clinical outcomes. METHODS In the SWEDEHEART (Swedish Web-system for enhancement and development of evidence-based care in heart disease evaluated according to recommended therapies) registry, all patients with MI treated with PCI and discharged on prasugrel or ticagrelor from 2010 to 2016 were included. Outcomes were 1-year major adverse cardiac and cerebrovascular events (MACCE, death, MI or stroke), individual components and bleeding. Multivariable adjustment, inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were used to adjust for confounders. RESULTS We included 37 990 patients, 2073 in the prasugrel group and 35 917 in the ticagrelor group. Patients in the prasugrel group were younger, more often admitted with ST elevation MI and more likely to have diabetes. Six to twelve months after discharge, 20% of patients in each group discontinued the P2Y12 receptor inhibitor they received at discharge. The risk for MACCE did not significantly differ between prasugrel-treated and ticagrelor-treated patients (adjusted HR 1.03, 95% CI 0.86 to 1.24). We found no significant difference in the adjusted risk for death, recurrent MI or stroke alone between the two treatments. There was no significant difference in the risk for bleeding with prasugrel versus ticagrelor (2.5% vs 3.2%, adjusted HR 0.92, 95% CI 0.69 to 1.22). IPTW and PSM analyses confirmed the results. CONCLUSION In patients with MI treated with PCI, prasugrel and ticagrelor were associated with similar efficacy and safety during 1-year follow-up.
