Abstract Introduction The impact of body mass index (BMI) on outcomes in patients with atrial fibrillation (AF) has been largely debated. Aims To describe the relationship between BMI categories and clinical outcomes in a large cohort of European AF patients. Methods We included all AF patients with available baseline BMI and creatinine clearance and 1-year follow-up data enrolled in the EORP-AF General Long-Term Registry. Outcomes considered were: i) a composite of any thromboembolic event (TE)/acute coronary syndrome (ACS)/cardiovascular (CV) death; ii) CV death; iii) all-cause death. Results A total of 7,759 patients were included in this analysis. Of these, 55 (0.7%) were underweight, 2,074 (26.7%) were normal weight, 3,170 (40.9%) were overweight, 1,703 (21.9%) were obese and 757 (9.8%) were severe obese. Mean age was progressively lower across the categories (p<0.0001), with proportion of patients aged≥75 years also progressively lower (52.7% in underweight to 19.4% in severe obese patients; p<0.001). Both underweight (41.8%) and severe obese (25.0%) patients were more likely symptomatic (p<0.001). Mean CHA2DS2-VASc score was higher in underweight patients (p=0.0325). Use of any oral anticoagulant therapy was progressively higher across the BMI categories (p<0.001). At 1-year follow-up the rate of all outcomes considered were highest for underweight patients and lowest in severe obese [Figure 1]. On univariate Cox regression analysis, being underweight was consistently associated to a higher risk for all outcomes, while increasing of weight categories was associated with progressively lower risk for adverse outcomes. After full adjustment with clinical and pharmacological characteristics, no effect of higher BMI classes was found for any outcome, but an independent association with an increased risk of CV death and all-cause death was seen for underweight patients (Table 1). Conclusions In a large cohort of European AF patients a progressively lower rate of outcomes was found across increasing BMI classes. After full adjustments, no significant association was found between the higher BMI classes and outcomes. Underweight was associated with an increased risk for CV death and all-cause death. Figure 1.

AbstractWe evaluated the association between nonalcoholic fatty liver disease (NAFLD) and incident atrial fibrillation (AF) and analyzed the impact of NAFLD on AF risk in relation to body mass index (BMI). A total of 8,048,055 subjects without significant liver disease who were available fatty liver index (FLI) values were included. Subjects were categorized into 3 groups based on FLI: < 30, 30 to < 60, and ≥ 60. During a median 8-year of follow-up, 534,442 subjects were newly diagnosed as AF (8.27 per 1000 person-years). Higher FLI was associated with an increased risk of AF (hazard ratio [HR] 1.053, 95% confidence interval [CI] 1.046–1.060 in 30 ≤ FLI < 60, and HR 1.115, 95% CI 1.106–1.125 in FLI ≥ 60). In underweight subjects (BMI < 18.5 kg/m2), higher FLI raised the risk of AF (by 1.6-fold in 30 ≤ FLI < 60 and by twofold in FLI ≥ 60). In normal- and overweight subjects, higher FLI was associated with an increased risk of AF, but the HRs were attenuated. In obese subjects, higher FLI was not associated with higher risk of AF. NAFLD as assessed by FLI was independently associated with an increased risk of AF in nonobese subjects with BMI < 25 kg/m2. The impact of NAFLD on AF risk was accentuated in lean subjects with underweight.

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 Introduction Frailty is a major health determinant for cardiovascular disease. Thus far, data on frailty in patients with atrial fibrillation (AF) are limited. Aims To evaluate frailty in a large contemporary cohort of European AF patients, the relationship with oral anticoagulant (OAC) prescription and with risk of all-cause death. Methods We analyzed patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. A 38-items frailty index (FI) was derived from baseline characteristics according to the accumulation of deficits model proposed by Rockwood and Mitnitsky. All-cause mortality was the primary study outcome. Results Out of the 11096 AF enrolled patients, data for evaluating frailty were available for 6557 (59.1%) patients who have been included in this analysis (mean [SD] age 68.9 [11.5], 37.7% females). Baseline median [IQR] CHA2DS2-VASc and HAS-BLED were 3 [2–4] and 1 [1–2], respectively. At baseline, median [IQR] FI was 0.16 (0.12–0.23), with 1276 (19.5%) patients considered “not-frail” (FI&lt;0.10), 4033 (61.5%) considered “pre-frail” (FI 0.10–0.25) and 1248 (19.0%) considered “frail” (FI≥0.25). Age, female prevalence, CHA2DS2-VASc and HAS-BLED progressively increased across the FI classes (all p&lt;0.001). Use of OAC progressively increased among FI classes; after adjustments FI was not associated with OAC prescription (odds ratio [OR]: 1.09, 95% confidence interval [CI]: 0.98–1.19 for each 0.10 FI increase). Conversely, FI was directly associated with vitamin K antagonist (VKA) use (OR: 1.26, 95% CI: 1.18–1.34 for each 0.10 FI increase) and inversely associated with non-VKA OACs (NOACs) use (OR: 0.82, 95% CI: 0.77–0.88). FI was significantly correlated with CHA2DS2-VASc (Rho= 0.516, p&lt;0.001). Over a median [IQR] follow-up of 731 [704–749] days, there were 569 (8.7%) all-cause death events. Kaplan-Meier curves [Figure] showed an increasing cumulative risk for all-cause death according to FI categories. A Cox multivariable analysis, adjusted for age, sex, type of AF and use of OAC, found that increasing FI as a continuous variable was associated with an increased risk of all-cause death (hazard ratio [HR]: 1.56, 95% CI: 1.40–1.73 for each 0.10 FI increase). An association with all-cause death risk was found across the FI categories (HR: 1.71, 95% CI: 1.23–2.38 and HR: 2.88, 95% CI: 2.02–4.12, respectively for pre-frail and frail patients compared to non-frail ones). FI was also predictive of all-cause death (c-index: 0.660, 95% CI: 0.637–0.682; p&lt;0.001). Conclusions In a European contemporary cohort of AF patients the burden of frailty is significant, with almost 1 out of 5 patients found to be “frail”. Frailty influenced significantly the choice of OAC therapy and was associated with (and predictive of) all-cause death at follow-up.

The Impact

Proposed treatments for severe and enduring anorexia nervosa (SE-AN) focus on quality of life, and psychological and social functioning. By de-emphasizing weight restoration as a priority, however, premature diagnosis of SE-AN may reduce potential for recovery. The present study assessed the effect of weight restoration, illness duration, and severity on treatment outcome 6 months after discharge from an intensive, meal-based behavioral treatment program. Participants included hospitalized adult women (N = 191) with AN or underweight other specified feeding and eating disorder (OSFED). Participants were characterized as short-term (ill &lt;7 years; n = 74) or long-term ill (ill ≥ 7 years; n = 117). Compared with short-term ill, long-term ill patients were older, had lower lifetime body mass index (BMI), more prior admissions, and exhibited greater depression and neuroticism. Long-term vs. short-term ill patients gained weight at the same rate (~2 kg/wk) and were equally likely to be weight restored by discharge (&gt;75% reached BMI ≥ 19 kg/m2 in both groups). At 6-month follow-up (n = 99), both groups had equivalent self-reported BMI, and depression, drive for thinness, body dissatisfaction, and bulimia scores. The only predictor of BMI ≥ 19 kg/m2 at follow-up was discharge BMI. The likelihood of a BMI ≥ 19 kg/m2 at follow-up was 5-fold higher for those with discharge BMI ≥ 19 kg/m2. Few studies of long-term ill inpatients with AN have examined the impact of full weight restoration on short-term outcomes. This study supports the therapeutically optimistic stance that, regardless of illness duration, hospitalized patients with AN benefit from gaining weight to a BMI ≥ 19 kg/m2.

Abstract Background Obesity has been shown to be related to an increased risk for incidence and progression of atrial fibrillation (AF). Meanwhile, the inverse association between body mass index (BMI) and mortality, so-called “obesity paradox”, is well-known among patients with AF, as well as other cardiovascular diseases. However, data regarding the relationship between BMI and specific causes of death in AF patients remain scarce. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto. The inclusion criterion for the registry is the documentation of AF at 12-lead electrocardiogram or Holter monitoring at any time. We started to enroll patients from March 2011, and baseline characteristics including BMI and follow-up data were available for 3,805 patients by the end of November 2018. Patients were categorized into 3 groups depending on the BMI value; underweight (<18.5 kg/m2; 419 patients), normal (18.5 to <25.0 kg/m2; 2,283 patients), overweight (≤25.0 kg/m2; 1,103 patients). Results In the entire population, the mean BMI level was 23.1±4.0 kg/m2. The lower BMI was associated with higher age (78.5±10.3, 74.0±10.3, and 71.3±10.9 years in Underweight, Normal, and Overweight, respectively; p<0.001) and with higher prevalence of various comorbidities and CHA2DS2-VASc scores (3.83±1.67, 3.43±1.70, and 3.29±1.64, p<0.001). Oral anticoagulants were less frequently prescribed in those with lower BMI (46%, 56%, and 58%, p<0.001). During a median follow-up of 1,464 days (interquartile range: 727–2,228 days), all-cause mortality was lower in accordance with higher BMI (14.3, 5.3, and 3.5 per 100 person-years, respectively; p<0.001). The proportion of infection as a cause of death was prominently higher in the Underweight group than the others (25.7%, 16.7%, and 13.4%, p<0.001) (Figure A). Furthermore, the mortality due to infection was consistently higher in Underweight than in the others in any of the age subgroups (Figure B). Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of the BMI value for mortality, adjusted by age, sex, chronic kidney disease, anemia, chronic obstructive pulmonary disease, history of major bleeding, and other components of CHA2DS2-VASc score. Higher BMI was related to lower all-cause mortality (per 5 kg/m2 increase: HR 0.71 [95% CIs 0.63–0.78], p<0.001), and also lower mortality due to infection (per 5 kg/m2 increase: HR 0.48 [95% CIs 0.37–0.61], p<0.001). Figure 1 Conclusions In a Japanese community-based AF cohort, obesity paradox was also observed on all-cause mortality. In particular, lower BMI was strongly associated with the mortality due to infection regardless of age.

Abstract Background Dyslipidemia is a disorder of lipid metabolism and associated with insulin resistance. The relationship between longitudinal body mass index (BMI) changes from childhood to adulthood and long-term dyslipidemia was explored in this study. Methods We assessed the longitudinal relationship between BMI changes since childhood and dyslipidemia among 1738 participants in rural areas of Hanzhong City, Shaanxi. All participants were initially examined between the ages of 6 and 15 years in 1987 and were reexamined in 1995, 2013 and 2017; the total follow-up duration was 30 years. Anthropometric measurements and blood biochemistry indexes were measured. Results We found that gradual progression of normal weight to overweight (OR = 1.65; 95% CI = 1.27, 2.15) or persistent overweight (OR = 2.45; 95% CI = 1.52, 3.96) from childhood to adulthood was associated with an increased risk of dyslipidemia in adulthood. And these risks were largely disappeared if the overweight or obesity during childhood was resolved by adulthood. The higher the BMI in adulthood and the younger the age at which overweight begins, the higher the risk of dyslipidemia. Conclusions Early weight loss and any degree of weight loss from childhood to adulthood can help improve dyslipidemia in adulthood. We further emphasize the importance of weight management and control in public health primary prevention.

Background: Data are limited regarding the association of cumulative burden and trajectory of body mass index (BMI) from early life with adult lipid disorders. Methods: The study cohort consisted of 5195 adults who had BMI repeatedly measured 4 to 21 times from childhood and had blood lipid measurements of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and information on lipid-lowering medications in the last adult survey. The area under the curve (AUC) was calculated as a measure of long-term burden (total AUC) and trends (incremental AUC) of BMI. Results: Participants with dyslipidemia, high LDL-C, low HDL-C and high TG had consistently and significantly higher BMI levels from childhood to adulthood compared to those with normal lipid levels. After adjusting for age, race, sex, and cohort, increased risk of adult dyslipidemia was significantly associated with higher values of childhood BMI, adulthood BMI, total AUC and incremental AUC, with odds ratio (95% confidence interval) = 1.22 (1.15–1.29), 1.85 (1.74–1.97), 1.61 (1.52–1.71), and 1.59 (1.50–1.69), respectively, and p < 0.001 for all. The association patterns were similar in most race–sex subgroups. Conclusions: Adults with dyslipidemia versus normal lipid levels have consistently higher levels and distinct life-course trajectories of BMI, suggesting that the impact of excessive body weight on dyslipidemia originates in early life.

Abstract Background: Although obesity is a well-recognised risk factor for cardiovascular disease (CVD), the impact of long-term body mass index (BMI) changes in overweight or obese adults, on the risk of heart failure, CVD and mortality has not been quantified. Methods: This population-based cohort study used routine UK primary care electronic health data linked to secondary care and death-registry records. We identified adults who were overweight or obese, free from CVD and who had repeated BMI measures. Using group-based trajectory modelling, we examined the BMI trajectories of these individuals and then determined incidence rates of CVD, heart failure and mortality associated with the different trajectories. Cox-proportional hazards regression determined hazards ratios for incident outcomes. Results: 264,230 individuals (mean age 49.5 years (SD 12.7) and mean BMI 33.8kg/m 2 (SD 6.1)) were followed-up for a median duration of 10.9 years. Four BMI trajectories were identified, corresponding at baseline, with World Health Organisation BMI classifications for overweight, class-1, class-2 and class-3 obesity respectively. In all four groups, there was a small, stable upwards trajectory in BMI (mean BMI increase of 1.06kg/m 2 (± 3.8)). Compared with overweight individuals, class-3 obese individuals had a 3.3-fold increased risk of heart failure (HR 3.26 (95% CI 2.98-3.57)), 2.7-fold increased risk of all-cause mortality (HR 2.72 (2.58-2.87)) and 3.3-fold increased risk of CVD-related mortality (HR 3.31 (2.84-3.86)) after adjusting for baseline demographic and cardiovascular risk factors. Conclusion: The majority of adults who are overweight or obese retain their degree of overweight or obesity over the long term. Individuals with stable severe obesity experience the worst heart failure, CVD and mortality outcomes. These findings highlight the high cardiovascular toll exacted by continuing failure to tackle obesity.

Af Recurrence

ObjectivesThe association between obesity and atrial fibrillation (AF) is well-established. We aimed to evaluate the impact of index body mass index (BMI) on AF recurrence at 12 months following catheter ablation using propensity-weighted analysis. In addition, periprocedural complications and fluoroscopy details were examined to assess overall safety in relationship to increasing BMI ranges.MethodsBaseline, periprocedural and follow-up data were collected on consecutive patients scheduled for AF ablation. There were no specific exclusion criteria. Patients were categorised according to baseline BMI in order to assess the outcomes for each category.ResultsAmong 3333 patients, 728 (21.8%) were classified as normal (BMI <25.0 kg/m2), 1537 (46.1%) as overweight (BMI 25.5–29.0 kg/m2) and 1068 (32.0%) as obese (BMI ≥30.0 kg/m2). Procedural duration and radiation dose were higher for overweight and obese patients compared with those with a normal BMI (p=0.002 and p<0.001, respectively). An index BMI ≥30 kg/m2 led to a 1.2-fold increased likelihood of experiencing recurrent AF at 12-months follow-up as compared with overweight patients (HR 1.223; 95% CI 1.047 to 1.429; p=0.011), while no significant correlation was found between overweight and normal BMI groups (HR 0.954; 95% CI 0.798 to 1.140; p=0.605) and obese versus normal BMI (HR 1.16; 95% CI 0.965 to 1.412; p=0.112).ConclusionsPatients with a baseline BMI ≥30 kg/m2 have a higher recurrence rate of AF following catheter ablation and therefore lifestyle modification to target obesity preprocedure should be considered in these patients.

Abstract Background Physical activity (PA) may have a beneficial contribution for outcomes in patients with atrial fibrillation (AF). Purpose We aimed to evaluate the impact of self-reported PA in a large contemporary cohort of European AF patients on the risk of all-cause mortality. Methods We analyzed patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Self-reported PA was categorized, on the basis of reported time spent exercising, as follows: i) No PA; ii) Occasional PA; iii) Regular PA; iv) Intense PA. The primary outcome was all-cause death. Results Over 11096, a total of 8699 (78.4%) patients (mean age (SD) 69.1 (11.5); 40.7% female) had available data about PA and follow-up observation and were included in the analysis. Of these, 3703 (42.6%) reported no PA, 2829 (32.5%) occasional PA, 1824 (21.0%) regular PA, with only 343 (3.9%) reporting intense PA. With the 4 increasing PA categories, mean age, proportion of female patients, CHA2DS2-VASc and HAS-BLED scores were progressively lower (all p&lt;0.001). Use of vitamin K antagonist (VKA) declined across the classes of PA (53.1% vs. 52.2% vs. 44.5% vs. 33.9%, p&lt;0.001), while use of non-VKA OACs (NOACs) conversely increased. During a mean (SD) 680.6 (171.5) days of follow-up, there were a total of 848 (9.7%) all-cause death events. Based on Kaplan-Meier analysis, there was a progressively lower cumulative risk for all-cause death according to PA categories [Figure]. A multivariable Cox regression analysis, adjusting for CHA2DS2-VASc score, use of OAC at baseline and type of AF, found a lower risk of all-cause death associated with increasing levels of PA (Hazard ratio [HR]: 0.69, 95% confidence interval [CI]: 0.59–0.81 for occasional PA, HR: 0.45, 95% CI: 0.35–0.58 for regular PA, HR: 0.41, 95% CI: 0.23–0.76 for intense PA, when compared to no PA). In a sensitivity analysis, a regular-intense PA was inversely associated with occurrence of cardiovascular (CV) death, after multivariable adjustments for comorbidities (HR: 0.54, 95% CI: 0.37–0.77). Conclusions In a large contemporary cohort of European AF patients, self-reported PA was found to be inversely associated with all-cause death and CV death.
