Abstract Background The number of incidences of atrial fibrillation (AF) is expected to rise rapidly in the near future because of the increased number of geriatric patients in Japanese society. In addition, obesity is increasing in the general Japanese population. Although a higher body mass index is associated with a higher risk of AF, the relationship between abdominal obesity (large waist circumference) and new-onset AF is unclear. Methods and results We performed a longitudinal retrospective observational study from January 2007 to October 2018 using the annual health checkup data. Data from 58,844 adults (29,572 males, age 54±13 years) without baseline AF, who underwent routine health checkups, were analyzed. We performed logistic regression analyses to determine the strength of the association between abdominal obesity and new-onset AF. We also examined the effect of abdominal obesity on the incidences of AF stratified by gender. During a median follow-up of 4 years, we recorded new cases of AF in 322 (0.5%) individuals. In univariate analysis, a large waist circumference was significantly associated with new-onset AF, both in males [hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.02 to 1.05, p<0.001] and in females (HR 1.04, 95% CI 1.01 to 1.06, p=0.002), respectively. In multivariate analysis adjusted for clinical variables (age, hypertension, dyslipidemia, estimated glomerular filtration rate, habitual drinking and diabetes), a large waist circumference was significantly and independently associated with new-onset AF in males (HR 1.04, 95% CI 1.03 to 1.06, p<0.001), but not in females (HR 1.01, 95% CI 0.99 to 1.04, p=0.269). Conclusion Abdominal obesity is independently associated with an increased risk of new-onset AF in males. This association in males might imply some sex-specific mechanisms. There might be a gender difference in the effectiveness of interventions to decrease abdominal obesity to prevent AF. Funding Acknowledgement Type of funding source: None

Background: There is increasing evidence that end-organ liver dysfunction is an important risk factor for atrial fibrillation (AF). Whether a non-invasive, laboratory-based marker of liver fibrosis, the fibrosis-4 score (FIB-4), is associated with incident AF is not known. Aim: To examine the longitudinal association of FIB-4 with incident AF in a general Japanese population with public health insurance. Methods: We used data from the National Japanese Health Check-Up performed in Kanazawa City, which included unemployed or retired participants aged ≥ 40 years. The baseline examination occurred in 2013 and participants were invited for annual routine examinations with follow-up data available through 2018. We excluded participants with pre-existing AF or missing data at baseline or follow-up. Incident AF was based on 12-lead electrocardiogram. We calculated the FIB-4 score (composed of age [years], aspartate and alanine aminotransferase, and platelet levels) for each participant and estimated the cumulative incidence of AF stratified by FIB-4 score quartiles. We also examined the association between quartiles of FIB-4 and incident AF using Cox proportional hazard models adjusted for risk factors with the lowest FIB-4 quartile as referent. Results: Of 37,892 participants, 37% were male and mean age was 72.4±9.6 years. Median (interquartile range [IQR]) of the FIB-4 score was 1.75 (IQR 1.38, 2.27). During a median (IQR) follow-up period of 5.0 years (4.0, 5.0), 707 cases of incident AF were identified. Cumulative incidence in the highest quartile of FIB-4 was 3.9% compared with 1.0% in the lowest quartile (log-rank p<0.001, Figure A ). Higher quartiles of the FIB-4 score had a dose-dependent increased risk of AF with adjusted HR of 1.70 (1.29, 2.23) in the highest quartile compared with the lowest quartile ( Figure B ). Conclusion: FIB-4 was independently associated with incident AF in a general, older Japanese population and may reflect risk of AF, in addition to traditional cardiovascular risk factors.

Abstract Funding Acknowledgements Type of funding sources: None. Background There are limited data on whether there is an association between hospitalisation with dental periapical abscess and new-onset atrial fibrillation (AF) which is independent of main cardiovascular risk factors. Purpose To investigate whether there is an association between hospitalisation with dental periapical abscess and new-onset AF. Methods A retrospective cohort study from a national database of patients hospitalised in 2013 (3.4 million patients) with at least five years of follow up, unless deceased. International Classification of Diseases (ICD) codes were used to compare the risk of developing new-onset AF for adults with and without dental periapical abscesses using univariate and multivariable analysis and hazard ratios (HR). Results In total, 4,693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess 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 &lt; 0.01). Conclusions An increased risk of new onset AF was identified for individuals hospitalised with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections are needed for incident AF, as well as investigations of possible mechanisms linking these conditions.

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.

Obesity has become a pandemic. It is one of the strongest risk-factors of new-onset chronic kidney disease (CKD). However, the effects of obesity and abdominal obesity on the risk of developing CKD in young adults has not been elucidated. From a nationwide health screening database, we included 3,030,884 young adults aged 20–39 years without CKD during a baseline examination in 2009–2010, who could follow up during 2013–2016. Patients were stratified into five levels based on their baseline body mass index (BMI) and six levels based on their waist circumference (WC; 5-cm increments). The primary outcome was the development of CKD. During the follow up, until 2016, 5853 (0.19%) participants developed CKD. Both BMI and WC showed a U-shaped relationship with CKD risk, identifying the cut-off values as a BMI of 21 and WC of 72 cm in young adults. The obesity group (odd ratio [OR] = 1.320, 95% confidence interval [CI]: 1.247–1.397) and abdominal obesity group (male WC ≥ 90, female WC ≥ 85) (OR = 1.208, 95%CI: 1.332–1.290) showed a higher CKD risk than the non-obesity or non-abdominal obesity groups after adjusting for covariates. In the CKD risk by obesity composite, the obesity displayed by the abdominal obesity group showed the highest CKD risk (OR = 1.502, 95%CI: 1.190–1.895), especially in those under 30 years old. During subgroup analysis, the diabetes mellitus (DM) group with obesity or abdominal obesity paradoxically showed a lower CKD risk compared with the non-obesity or non-abdominal obesity group. Obesity and abdominal obesity are associated with increased risk of developing CKD in young adults but a decreased risk in young adults with diabetes.

Background: Little data are available regarding differences in prognosis and health status between new-onset and prior atrial fibrillation (AF) among patients with acute myocardial infarction (AMI). Methods: The TRIUMPH study enrolled 4340 AMI patients who received longitudinal follow-up including SF-12 health status assessments through 1 year post-AMI. We compared 1-year mortality, rehospitalization, and functional status according to AF type (none, prior, new) after adjusting for differences in baseline characteristics. Results: A total of 212 AMI patients (4.9%) had prior AF and 254 (5.9%) had new-onset AF. Compared with no AF, new AF was associated with older age, male sex, first MI, worse baseline physical function, home atrioventricular nodal blocker use, and worse ventricular function (c-index 0.77). Rates of 1-year mortality were 6.2%, 14.5%, and 13.0%, and 1-year rehospitalization rates were 29.1%, 44.2%, and 36.8% for no, prior, and new AF, respectively. After multivariable adjustment, neither prior nor new AF was associated with increased 1-year mortality, and only prior AF was associated with increased risk of 1-year rehospitalization (Figure). After adjusting for baseline SF-12 physical function scores, patients with prior AF had lower 1-year scores than those with no AF (40.6 vs. 43.7, p <0.003), whereas patients with new AF had similar scores (42.9 vs. 43.7, p=0.36). Conclusion: New-onset AF during AMI is associated with a number of comorbidities but, unlike prior AF, is not associated with adverse outcomes. These results raise the question of whether AF is itself a cause of or simply a marker of comorbidities leading to downstream adverse outcomes after AMI.

Abstract Context The association of the combination of body mass index (BMI) and waist circumference (WC) with the risk of proteinuria has previously not been comprehensively investigated and results have been inconclusive. Objective To examine BMI and WC in relation to new-onset proteinuria in Chinese hypertensive patients. Design and Setting Post hoc analysis of the renal substudy of the China Stroke Primary Prevention Trial (CSPPT). Patients 10 805 hypertensive patients without proteinuria at baseline. Main Outcome Measure The primary outcome was new-onset proteinuria, defined as a urine dipstick protein reading ≥ 1 + at the exit visit, after a median follow-up duration of 4.4 years. Results When analyzed separately, increased BMI (≥ 28 kg/m2, quartile 4; odds ratio [OR], 1.36; 95% confidence interval [CI], 1.08–1.72), or increased WC (≥ 91cm for females, quartile 4; OR, 1.35; 95% CI, 1.01–1.80; and ≥ 79 cm for males, quartile 2–4; OR, 1.60; 95% CI, 1.03–2.50) were each significantly associated with higher risk of new-onset proteinuria. When analyzed jointly, participants without increased BMI and increased WC had the lowest risk, while those with both increased BMI and increased WC had the highest risk of proteinuria (OR, 1.61; 95% CI, 1.21–2.13). Notably, participants with only increased WC also had significantly increased risk of proteinuria (OR, 1.39; 95% CI, 1.04–1.85). Conclusion In Chinese hypertensive patients, increased BMI and increased WC were individually and jointly associated with a higher risk of new-onset proteinuria, underscoring the value of monitoring both BMI and WC in assessing proteinuria risk.

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.

AbstractAtrial fibrillation (AF) is associated with various major adverse cardiac events such as ischemic stroke, heart failure, and increased overall mortality. However, its association with lethal ventricular arrhythmias such as ventricular tachycardia (VT), ventricular flutter (VFL), and ventricular fibrillation (VF) is controversial. We conducted this study to determine whether AF can increase the risk of VT, VFL, and VF. We utilized the Korean National Health Insurance Service database for this nationwide population-based study. This study enrolled people who underwent a nationwide health screen in 2009 for whom clinical follow-up data were available until December 2018. Primary outcome endpoint was the occurrence of VT, VFL, or VF in people who were and were not diagnosed with new-onset AF in 2009. We analyzed a total of 9,751,705 people. In 2009, 12,689 people were diagnosed with new-onset AF (AF group). The incidence (events per 1000 person-years of follow-up) of VT, VFL, and VF was 2.472 and 0.282 in the AF and non-AF groups, respectively. After adjustment for covariates, new-onset AF was associated with 4.6-fold increased risk (p < 0.001) of VT, VFL, and VF over 10 years of follow-up. The risk of VT, VFL, and VF was even higher if identification of AF was based on intensified criteria (≥ 2 outpatient records or ≥ 1 inpatient record; hazard ratio = 5.221; p < 0.001). In conclusion, the incidence of VT, VFL, and VF was significantly increased in people with new-onset AF. The potential risk of suffering lethal ventricular arrhythmia in people with AF should be considered in clinical practice.

Introduction: New onset postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery that is associated with an increased risk for stroke and all-cause mortality. Long term data on POAF recurrence and anticoagulation remains sparse. We aimed to characterize the natural progression and recurrence of new onset POAF during a long-term follow up post cardiac surgery utilizing continuous event monitoring. Methods: This is a single-center, prospective observational study evaluating 42 patients undergoing cardiac surgery and diagnosed during indexed admission with new onset, transient POAF who were discharged in sinus rhythm between May 2015 and December 2019. Prior to discharge, all patients received implantable loop recorders (ILR) for continuous monitoring. Study outcomes were the presence and timing of AF recurrence (first and repeated AF recurrence), all-cause mortality and cerebrovascular accidents (CVA). Results: Forty-two patients [mean age 67.6± 9.6 years, 74% male, mean CHADS 2- VASc 3.5±1.5] were evaluated during a mean follow-up of 1.7 ± 1.2 years. AF recurrence after discharge occurred in 30 patients (71%). Twenty-four of these 30 patients (80%) had their first AF recurrence within the first month, 3 (10%) patients during months 1-12, and 3 (10%) patients beyond 1 year. Repeated AF recurrence occurred in 13 (43%) patients between 1 and 12-months. Beyond one year of follow-up, 5 (17%) patients had either their first AF recurrence (3) or repeated AF recurrence (2). During follow-up, there was one death ((-) AF recurrence) and two CVAs ((+) AF recurrence). Conclusions: In this study of continuous monitoring with ILR , the recurrence of AF in patients who develop transient POAF is common. Seventy percent of patients had either their first AF recurrence 6 (20%) or repeated episodes of recurrent AF 15 (50%) after 1-month post-operative follow-up.
