Abstract Background Atrial fibrillation (AF) is a global health care problem with evidence suggesting an increasing prevalence and incidence worldwide. Undiagnosed AF represents the most common cause of thromboembolic events. The aim of the study was to analyze the clinical profile and outcome in patients with cardioembolic stroke and newly detected AF. Methods We enrolled 139 consecutive patients with atrial fibrillation and confirmed diagnosis of ischemic stroke (mean age 72.25±6.33 years, 59 male). Follow-up period was 1 year since the episode of acute stroke. Results All patients with verified cardioembolic stroke were first diagnosed with AF on admission. Patients with AF were characterized by polymorbidity (hypertension was diagnosed in 96 patients, a concomitant chronic renal failure was observed in 60 cases while a complicated course of coronary heart disease – in 35 patients, 22 patients were diagnosed with diabetes mellitus, while 9 people had a long smoking history). Mean value of CHA2DS2-VASc score was 4.51±1.2 and after acute stroke patients were recommended permanent anticoaugulation (12% – warfarin, 45% – rivaroxaban, 24% – apixaban and 19% – dabigatran). At the end of the year of follow-up patients were taking oral anticoagulants only in 16.2% of cases. In the same time only 9.9% of patients had a history of mild or moderate nasal or gingival bleeding (8.2%) while severe hemorrages were not reported. On multivariable analysis, lack of antithrombotic treatment guideline adherence was associated with increased risk of recurrent stroke (hazard ratio, 4.45; 95% confidence interval, 1.25–6.87; P=0.012 for undertreatment). For 3 (2.2%) patients the recurrent sroke was fatal and 2 (1.4%) patients had lethal outcome due to heart failure deterioration after 6 months of follow up. During one year follow up 27 (19.4%) patients had spontaneous AF conversion into sinus rhythm and 19 (13.7%) patients underwent successful catheter ablation. The adjusted risk of reccurent stroke for those in chronic AF was higher than in sinus rhythm (hazard ratio, 1.70; 95% CI, 1.37–2.12). Conclusions This study showed that patients with newly dignosed AF and cardioembolic stroke are characterized with polymorbidity and high thromboembolic risk but after sinus rhythm restoration the adjusted risk of reccurent stroke is much lower. The results demonstrate a low quality care of patients with AF and cardioembolic stroke at the outpatient stage. Appropriate medication compliance is crucial for positive outcomes as well as effectivesecondary stroke prevention in AF patients. FUNDunding Acknowledgement Type of funding sources: None.

Background Atrial fibrillation is the most common heart rhythm disorder, and high body mass index is a well-established risk factor for atrial fibrillation. The objective of this study was to examine the associations of physical activity and body mass index and risk of atrial fibrillation, and the modifying role of physical activity on the association between body mass index and atrial fibrillation. Design The design was a prospective cohort study. Methods This study followed 43,602 men and women from the HUNT3 study in 2006–2008 until first atrial fibrillation diagnosis or end of follow-up in 2015. Atrial fibrillation diagnoses were collected from hospital registers and validated by medical doctors. Cox proportional hazard regression analysis was performed to assess the association between physical activity, body mass index and atrial fibrillation. Results During a mean follow-up of 8.1 years (352,770 person-years), 1459 cases of atrial fibrillation were detected (4.1 events per 1000 person-years). Increasing levels of physical activity were associated with gradually lower risk of atrial fibrillation ( p trend 0.069). Overweight and obesity were associated with an 18% (hazard ratio 1.18, 95% confidence interval 1.03–1.35) and 59% (hazard ratio 1.59, 95% confidence interval 1.37–1.84) increased risk of atrial fibrillation, respectively. High levels of physical activity attenuated some of the higher atrial fibrillation risk in obese individuals (hazard ratio 1.53, 95% confidence interval 1.03–2.28 in active and 1.96, 95% confidence interval 1.44–2.67 in inactive) compared to normal weight active individuals. Conclusion Overweight and obesity were associated with increased risk of atrial fibrillation. Physical activity offsets some, but not all, atrial fibrillation risk associated with obesity.

Abstract Background There are limited data about the impact of modifying behavior such as smoking cessation after atrial fibrillation (AF) diagnosis on the clinical outcome. Purpose To evaluate the association between smoking cessation after newly diagnosed AF and the risk of stroke. Methods Among subjects with new-onset AF between 2010 and 2016, those who received a national health checkup exam within 2 years before and after the AF diagnosis were included. Subjects were categorized into 4 groups according to the status of smoking before and after AF diagnosis: (i) never smoker; (ii) new smoker after AF diagnosis; (iii) quit-smoker after AF diagnosis; and (iv) persistent smoker. The primary outcome was incident stroke during follow-up. Results A total of 97,869 patients were included (mean age 61±12, men 62%, and mean CHA2DS2-VASc 2.3±1.5). During a median of 3 years of follow-up, stroke occurred in 3,121 patients (1.0 per 100 person-years). Never smoker, new smoker, quit-smoker, and persistent smoker was 79%, 2%, 7%, and 12% of the total study population, respectively. After multivariable adjustment, new smoker and persistent smoker were associated with an increased risk of stroke compared to never smoker (hazard ratio [HR] 1.84, 95% confidence interval [CI] 1.48–2.28 for new smoker; HR 1.66, 95% CI 1.48–1.86 for persistent smoker) (Figure). Quit-smoker who stopped smoking after AF diagnosis also showed a higher risk of stroke than never smoker (HR 1.19, 95% CI 1.03–1.38). The quit-smoker group showed a lower compared to those who continued smoking after AF diagnosis (HR 0.720, 95% CI 0.608–0.851). Conclusion Smoking cessation after AF diagnosis showed a lower risk of stroke compared to patients smoking persistently. Lifestyle change as smoking cessation after diagnosis of AF could modify the risk of stroke in patients with new-onset AF.

Abstract Background In patients with acute myocardial infarction (AMI), history of atrial fibrillation (AF) and new onset AF during the early phase may be associated with a worse prognosis. Whether both conditions are associated with a similar risk of stroke and should be similarly managed is a matter of debate. Methods Based on the administrative hospital-discharge database, we collected information for all patients treated with AMI between 2010 and 2019 in France. The adverse outcomes were investigated during follow-up. Results Among 797,212 patients with STEMI or NSTEMI, 146,922 (18.4%) had history of AF, and 11,824 (1.5%) had new AF diagnosed between day 1 and day 30 after AMI. Patients with new AF were older and had more comorbidities than those with no AF but were younger and had less comorbidities than those with history of AF. Both groups with history of AF or new AF had less frequent STEMI and anterior MI, less frequent use of percutaneous coronary intervention but more frequent HF at the acute phase than patients with no AF. During follow-up (mean [SD] 1.8 [2.4] years, median [interquartile range] 0.7 [0.1–3.1] years), 163,845 deaths and 20,168 ischemic strokes were recorded. Using Cox multivariable analysis, compared to patients with no AF, history of AF was associated with a higher risk of death during follow-up (adjusted hazard ratio HR 1.06 95% CI 1.05–1.08) while this was not the case for patients with new AF (adjusted HR 0.98 95% CI 0.95–1.02). By contrast, both history of AF and new AF were associated with a higher risk of ischemic stroke during follow-up compared to patients with no AF: adjusted hazard ratio HR 1.29 95% CI 1.25–1.34 for history of AF, adjusted HR 1.72 95% CI 1.59–1.85 for new AF. New AF was associated with a higher risk of ischemic stroke than history of AF (adjusted HR 1.38 95% CI 1.27–1.49). Conclusion In a large and systematic nationwide analysis, AF first recorded in the first 30 days after AMI was associated with an increased risk of ischemic stroke. Specific management should be considered in order to improve outcomes in these patients after AMI. Funding Acknowledgement Type of funding source: None

Introduction: Atrial Fibrillation (AF) is the most common serious cardiac arrhythmia and is associated with an increased risk of stroke and mortality. These risks can be modified with oral anticoagulation therapy. Clinically, the arrhythmia can be permanent or intermittent. Prior studies that have used time-constant, categorical covariates to examine the relationship between the pattern of AF and the occurrence of adverse events have produced conflicting results. We hypothesized that the amount of time that patients spend in AF, hereinafter termed arrhythmia “burden”, may be important in predicting adverse events. Objective: To examine the effects of the burden of AF on all-cause mortality. Methods: The Manitoba Follow-Up Study is a longitudinal, prospective study of 3983 originally healthy young men (mean age at entry 30 years) who have been followed with routine medical and electrocardiographic examinations since 1948. After 60 years of follow-up to July 1, 2008, AF had been documented on the electrocardiograms of 581 men (15% of the cohort) and 3182 (80%) of the original cohort had died. We created a Cox proportional hazards model with time-dependent covariates to estimate relative risks for mortality according to AF burden. AF status during each follow-up visit was classified as persistent when the patient was in AF on consecutive examinations, transient when the patient reverted to sinus rhythm after being in AF and incident when the patient developed AF after a period in sinus rhythm. Results: Results of the Cox proportional hazards regression model are displayed in the Table. Age, persistent AF and incident AF were all significant variables in the model. Holding all the other variables constant, persistent AF increased the risk of death by two times and incident AF increased the risk of death by 87%. Conclusions: Persistent AF and incident AF are associated with increased all-cause mortality. Estimating AF burden may have implications for risk stratification in patients with AF.

Abstract Background and purpose Although several studies reported that stroke risk in patients with paroxysmal atrial fibrillation (AF) is similar to those with persistent or permanent AF, there is still controversy on the relationship of AF type and stroke occurrence. We investigated the effect of AF type on AF burden and stroke risk in patients with non-valvular AF. Methods Within the CODE-AF prospective, outpatient registry (COmparison study of Drugs for symptom control and complication prEvention of Atrial Fibrillation), we identified 8,883 patients ≥18 years of age with non-valvular AF and eligible follow-up visits. We compared AF burden and stroke risk among patients with 3 types of AF: paroxysmal (n=5,808) or persistent (n=2,806) or permanent (n=269). Results The median age of the overall population was 68.0 (interquartile range, 60.0–75.0); 36.0% were female. Patients with persistent and permanent AF were older and had higher CHA2DS2-VASc scores and anticoagulation rate than those with paroxysmal AF. Compared with permanent AF (5.2±16.4%), the arrhythmic burden of AF on 24hrs Holter monitoring was significantly lower in paroxysmal AF (2.1±7.2%, p<0.001) and persistent AF (2.0±7.5%, p<0.001). During median follow-up period of 1.38 years (interquartile range: 0.96–1.67), total 82 (0.92%) patients experienced ischemic stroke with incidence rates of 0.51, 1.04 and 1.69 events per 100 person-years for paroxysmal, persistent and permanent AF, respectively. Compared with paroxysmal AF, the risk of ischemic stroke was increased in persistent AF with clinical variable adjusted hazard ratio (aHR) of 1.94 (95% confidence intervals [CI], 1.23–3.07; P=0.005) and permanent AF with aHR of 2.64 (95% CI, 1.09–6.41; P=0.03).

Conclusion Persistent and permanent AF was associated with the increased risk of stroke than paroxysmal AF, after adjustment of clinical variables including age, sex, comorbidities and anticoagulation rate. These results suggest that AF type and burden might be related with the risk of ischemic stroke and should be considered in the stroke prevention of AF.

Introduction: Epidemiologic evidence supports an inverse and strong association between fitness status, and mortality in healthy individuals. Pre-hypertensive individuals are at increased risk for cardiovascular events compared to those with normal blood pressure. However, there is no information on the association between exercise capacity and mortality in pre-hypertensive individuals. Methods: We assessed the association between peak exercise capacity (METs) and all-cause mortality in pre-hypertensive men (n=4,735; age=56±12). We established four fitness categories based on the MET level achieved. Those who achieved <5 METs (n=674); 5–7 METs (n=1,170); 7.1 to 10 METs (1,784); and > 10 METs (n= n=1,107). There were 943 deaths over 22 years of follow-up (mean=8.0±5.5). Results : After adjusting for age, BMI, diabetes and dyslipidemia, exercise capacity was the strongest predictor of risk for mortality. The adjusted risk was reduced by 14% for every 1-MET increase in exercise capacity (Hazard Ratio= 0.86; CI: 0.84 – 0.88; p<0.001). When compared to those who achieved ≥5 METs, the mortality risk in those who achieved 5.1–7 METs was 25% lower (hazard ratio= 0.75; CI: 0.64 – 0.87; p<0.001); 60% lower for those who achieved 7.1–10 METs (hazard ratio= 0.40; CI: 0.33– 0.48; p<0.001), and 75% lower for those achieving >10 METs (Hazard Ratio= 0.25; CI: 0.19 – 0.33; p<0.001). Conclusions: The association between exercise capacity and mortality in pre-hypertensive individuals was strong, inverse and graded. The mortality risk was lowered by 14% for each 1-MET increase in exercise capacity. The overall reduction in mortality was 25% to 75% for those with an exercise capacity of >7 METs compared to those who achieved <5 METs.

There are limited data on the relationship of acute dental infections with hospitalisation and new-onset atrial fibrillation (AF). This study aimed to assess the relationship between acute periapical abscess and incident AF. This was a retrospective cohort study from a French national database of patients hospitalized in 2013 (3.4 million patients) with at least five years of follow up. In total, 3,056,291 adults (55.1% female) required hospital admission in French hospitals in 2013 while not having a history of AF. Of 4693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess that developed AF over a mean follow-up of 4.8 ± 1.7 years. Multivariable analysis indicated that dental periapical abscess acted as an independent predictor for new onset AF (p < 0.01). The CHA2DS2VASc score in patients with acute dental periapical abscess had moderate predictive value for development of AF, with Area Under the Curve (AUC) 0.73 (95% CI, 0.71–0.76). An increased risk of new onset AF was identified for individuals hospitalized with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections is needed for incident AF, as well as investigations of possible mechanisms linking these conditions.

ABSTRACT The long-term inflammatory impact of diet could potentially elevate the risk of periodontal disease through modification of systemic inflammation. The aim of the present study was to prospectively investigate the associations between a food based, reduced rank regression (RRR) derived, empirical dietary inflammatory pattern (EDIP) and incidence of periodontitis. The study population was composed of 34,940 men from the Health Professionals Follow-Up Study, who were free of periodontal disease and major illnesses at baseline (1986). Participants provided medical and dental history through mailed questionnaires every 2 years, and dietary data through validated semi-quantitative food frequency questionnaires every 4 years. We used Cox proportional hazard models to examine the associations between EDIP scores and validated self-reported incidence of periodontal disease over a 24-year follow-up period. No overall association between EDIP and the risk of periodontitis was observed; the hazard ratio comparing the highest EDIP quintile (most proinflammatory diet) to the lowest quintile was 0.99 (95% confidence interval: 0.89 -1.10, p-value for trend = 0.97). A secondary analysis showed that among obese non-smokers (i.e. never and former smokers at baseline), the hazard ratio for periodontitis comparing the highest EDIP quintile to the lowest was 1.39 (95% confidence interval: 0.98 -1.96, p-value for trend = 0.03). In conclusion, no overall association was detected between EDIP and incidence of self-reported periodontitis in the study population. From the subgroups evaluated EDIP was significantly associated with increased risk of periodontitis only among nonsmokers who were obese. Hence, this association must be interpreted with caution.

The aim of this study was to explore sex-specific associations between systolic blood pressure (SBP), hypertension, and the risk of incident atrial fibrillation (AF) subtypes, including paroxysmal, persistent, and permanent AF, in a general population. A total of 13,137 women and 11,667 men who participated in the fourth survey of the Tromsø Study (1994–1995) were followed up for incident AF until the end of 2016. Cox proportional hazards regression analysis was conducted using fractional polynomials for SBP to provide sex- and AF-subtype-specific hazard ratios (HRs) for SBP. An SBP of 120 mmHg was used as the reference. Models were adjusted for other cardiovascular risk factors. Over a mean follow-up of 17.6 ± 6.6 years, incident AF occurred in 914 (7.0%) women (501 with paroxysmal/persistent AF and 413 with permanent AF) and 1104 (9.5%) men (606 with paroxysmal/persistent AF and 498 with permanent AF). In women, an SBP of 180 mmHg was associated with an HR of 2.10 (95% confidence interval [CI] 1.60–2.76) for paroxysmal/persistent AF and an HR of 1.80 (95% CI 1.33–2.44) for permanent AF. In men, an SBP of 180 mmHg was associated with an HR of 1.90 (95% CI 1.46–2.46) for paroxysmal/persistent AF, while there was no association with the risk of permanent AF. In conclusion, increasing SBP was associated with an increased risk of both paroxysmal/persistent AF and permanent AF in women, but only paroxysmal/persistent AF in men. Our findings highlight the importance of sex-specific risk stratification and optimizing blood pressure management for the prevention of AF subtypes in clinical practice.
