Introduction: Atrial fibrillation (AF) is a leading cause of cardiovascular morbidity and mortality. Disparities in AF outcomes have been related to individual-level social determinants of health, including race/ethnicity and socioeconomic status. While neighborhood-level factors, such as poverty, have been related to prevalence of key risk factors (e.g. obesity, hypertension), the association between neighborhood poverty and incident AF has not been previously examined. Methods: Using the Northwestern Medicine Enterprise Data Warehouse, we identified adults free of cardiovascular disease, with at least 5 years of follow-up from January 1, 2005 - December 31, 2013. Residential addresses were geocoded and matched to census tract level poverty estimates from the American Community Survey. Neighborhood poverty was defined as the proportion of residents in the census tract living below the US-defined poverty threshold. We categorized neighborhood poverty levels into tertiles. Generalized linear mixed effects models were used to examine the association between tertiles of neighborhood poverty and incident AF, adjusting for demographic (age, sex, race/ethnicity, insurance type) and AF risk factors (hypertension, diabetes, obesity and smoking status). Results: The cohort comprised 29,069 adults with a mean (SD) age of 51.4 (11.3) years, which included 58% women and 10% non-Hispanic Blacks. Higher rates of obesity, diabetes, hypertension, and smoking were observed in higher poverty groups. Approximately, 3.4% of patients developed incident AF over a follow-up of 5 years. The adjusted odds of incident AF were higher for the medium poverty compared to the low poverty group (adjusted odds ratio, aOR 1.30 (95% CI 1.05-1.56). The aOR of incident AF was similarly higher in the high poverty compared to low poverty group though not statistically significant (Table). Conclusions: In a cohort of adults free of cardiovascular disease at baseline, we found that residence in a more deprived neighborhood was associated with higher rates of incident AF, even after adjustment for traditional risk factors. Understanding how neighborhood and individual-level clinical factors interact to increase the incidence of AF is critical to developing equitable prevention strategies in this increasingly common condition.

Background Black individuals have a higher burden of risk factors for heart failure (HF) and subclinical left ventricular remodeling. Methods and Results We evaluated 1871 Black participants in the Atherosclerosis Risk in Communities Study cohort who attended a routine examination (1993–1996, median age 58 years) when they underwent echocardiography. We estimated the prevalences of 4 HF stages: (1) Stage 0 : no risk factors; (2) Stage A : presence of HF risk factors (hypertension, diabetes mellitus, obesity, smoking, dyslipidemia, coronary artery disease without clinical myocardial infarction), no cardiac structural/functional abnormality; (3) Stage B : presence of prior myocardial infarction, systolic dysfunction, left ventricular hypertrophy, regional wall motion abnormality, or left ventricular enlargement; and (4) Stage C/D : prevalent HF. We assessed the incidence of clinical HF, atherosclerotic cardiovascular disease events, and all‐cause mortality on follow‐up according to HF stage. The prevalence of HF Stages 0, A, B, and C/D were 3.8%, 20.6%, 67.0%, and 8.6%, respectively, at baseline. On follow‐up (median 19.0 years), 309 participants developed overt HF, 390 incurred new‐onset cardiovascular disease events, and 651 individuals died. Incidence rates per 1000 person‐years for overt HF, cardiovascular disease events, and death, respectively, were Stage 0, 2.4, 0.8, and 7.6; Stage A, 7.4, 9.7, and 13.5; Stage B 13.6, 15.9, and 22.0. Stage B HF was associated with a 1.5‐ to 2‐fold increased adjusted risk of HF, cardiovascular disease events and death compared with Stages 0/A. Conclusions In our large community‐based sample of Black individuals, we observed a strikingly high prevalence of Stage B HF in middle age that was a marker of high cardiovascular morbidity and mortality.

Background:Cardiovascular (CVS) diseases are the leading cause of death worldwide and patients with rheumatic diseases have an increased CVS risk including stroke and myocardial infarction (MI) (1-3). CVS risk factors and CVS events are common in SpA (4). Delineating the CVS risk and the association with medications in patients with SpA would be useful.Objectives:The objective of this study was to delineate the CVS risk and the association with medications in patients with SpA.Methods:Patients with SpA and patients with non-specific back pain (NSBP) were identified in rheumatology and orthopedics clinics respectively. Clinical information and CVS events were retrieved. Incidence rates were calculated. Association analysis was performed to determine the CVS risk of SpA and other modifiable risk factors.Results:A total of 5046 patients (SpA 2616 and NSBP 2430) were included from eight centers. Over 56 484 person-years of follow-up, 160 strokes, 84 MI and 262 major adverse cardiovascular events (MACE) were identified. Hypercholesterolemia was more prevalent in SpA (SpA 34.2%, NSBP 28.7%, P<0.01). Crude incidence rates of stroke and MI were higher in SpA patients. SpA was associated with a higher risk of MACE (HR 1.66, 95%CI 1.22-2.27, P<0.01) and cerebrovascular events (HR 1.42, 95%CI 1.01-2.00, p=0.04). The use of anti-tumor necrosis factor (TNF) drugs was associated with a reduced risk of MACE (HR 0.37, 95%CI 0.17-0.80, P=0.01) and cerebrovascular events (HR 0.21, 95%CI 0.06-0.78, P=0.02).Conclusion:SpA is an independent CVS risk factor. Anti-TNF drugs were associated with a reduced CVS risk in these patients.References:[1]Crowson CS, Liao KP, Davis JM, 3rd, Solomon DH, Matteson EL, Knutson KL, et al.

Abstract Background The prevalence and incidence rate of atrial fibrillation (AF) increase worldwide and AF is a risk factor for more adverse cardiovascular diseases including stroke. Approximately 44% of AF cases cannot be explained by common individual risk factors and risk might therefore also be related to the environment. By studying geographical variation and clustering in risk of incident AF adjusted for socioeconomic position at an individual level, potential neighbourhood risk factors could be revealed. Methods Initially, yearly AF incidence rates 1987–2015 were estimated overall and stratified by income in a register-based cohort study. To examine geographical variation and clustering in AF, we used both spatial scan statistics and a hierarchical Bayesian Poisson regression analysis of AF incidence rates with random effect of municipalities (n = 98) in Denmark in 2011–2015. Results The 1987–2015 cohort included 5,453,639 individuals whereof 369,800 were diagnosed with an incident AF. AF incidence rate increased from 174 to 576 per 100,000 person-years from 1987 to 2015. Inequality in AF incidence rate ratio between highest and lowest income groups increased from 23% in 1987 to 38% in 2015. We found clustering and geographical variation in AF incidence rates, with incidence rates at municipality level being up to 34% higher than the country mean after adjusting for socioeconomic position. Conclusions Geographical variations and clustering in AF incidence rates exist. Compared to previous studies from Alberta, Canada and the United States, we show that geographical variations exist in a country with free access to healthcare and even when accounting for socioeconomic differences at an individual level. An increasing social inequality in AF was seen from 1987 to 2015. Therefore, when planning prevention strategies, attention to individuals with low income should be given. Further studies focusing on identification of neighbourhood risk factors for AF are needed.

Atrial fibrillation is one of the most common arrhythmias, with a significant increase in incidence in recent years. AF is a major cause of stroke, heart failure, sudden cardiac death, and cardiovascular disease. Timely intervention and modification of risk factors increase chance to stop the disease. Aggressive, multilevel prevention tactics are a component of combined treatment, including – in addition to lifestyle changes, anticoagulant therapy, pharmacotherapy and invasive anti-arrhythmic treatment – prevention of cardiovascular diseases, hypertension, ischemia, valvular disease and heart failure.

ObjectivesWe examined the dose–response relationship between physical activity (PA) and incidence of cardiovascular disease (CVD) risk factors in adults in Taiwan.MethodsThis study included 1 98 919 participants, aged 18–97 years, free of CVD, cancer and diabetes at baseline (1997–2013), who were followed until 2016. At baseline, participants were classified into five PA levels: inactive’ (0 metabolic equivalent of task (MET)-h/week), ‘lower insufficiently active’ (0.1–3.75 MET-h/week), ‘upper insufficiently active’ (3.75–7.49 MET-h/week), ‘active’ (7.5–14.99 MET-h/week) and ‘highly active’ (≥15 MET-h/week]. CVD risk factors were assessed at baseline and at follow-up by physical examination and laboratory tests. Analyses were performed with Cox regression and adjusted for the main confounders.ResultsDuring a mean follow-up of 6.0±4.5 years (range 0.5–19 years), 20 447 individuals developed obesity, 19 619 hypertension, 21 592 hypercholesterolaemia, 14 164 atherogenic dyslipidaemia, 24 275 metabolic syndrome and 8548 type 2 diabetes. Compared with inactive participants, those in the upper insufficiently active (but not active) category had a lower risk of obesity (HR 0.92; 95% CI 0.88 to 0.95), atherogenic dyslipidaemia (0.96; 0.90 to 0.99), metabolic syndrome (0.95; 0.92 to 0.99) and type 2 diabetes (0.91; 0.86 to 0.97). Only highly active individuals showed a lower incidence of CVD risk factors than their upper insufficiently active counterparts.ConclusionCompared with being inactive, doing half the recommended amount of PA is associated with a lower incidence of several common biological CVD risk factors. Given these benefits, half the recommended amount of PA is an evidence based target for inactive adults.

Vascular injury mobilizes bone marrow–derived proangiogenic cells into the circulation, where these cells can facilitate vascular repair and new vessel formation. We sought to determine the relationship between a new biomarker of circulating bone marrow–derived proangiogenic cell activity, the presence of atherosclerotic cardiovascular disease (CVD) and its risk factors, and clinical outcomes. Circulating proangiogenic cell activity was estimated using a reproducible angiogenic colony-forming unit (CFU-A) assay in 532 clinically stable subjects aged 20 to 90 years and ranging in the CVD risk spectrum from those who are healthy without risk factors to those with active CVD. CFU-A counts increased with the burden of CVD risk factors ( p < 0.001). CFU-A counts were higher in subjects with symptomatic CVD than in those without ( p < 0.001). During follow-up of 232 subjects with CVD, CFU-A counts were higher in those with death, myocardial infarction, or stroke than in those without (110 [70–173] vs 84 [51–136], p = 0.01). Therefore, we conclude that circulating proangiogenic cell activity, as estimated by CFU-A counts, increases with CVD risk factor burden and in the presence of established CVD. Furthermore, higher circulating proangiogenic cell activity is associated with worse clinical outcome in those with CVD.

Outpatient statin use is known to reduce the risk of recurrent ischemic stroke of atherothrombotic etiology, but it is not known whether statins have similar effects in ischemic stroke associated with atrial fibrillation (AF). We examined the relationship between outpatient statin adherence and the risk of recurrent ischemic stroke in patients with or without AF in a large integrated healthcare delivery system. Among 6,283 patients with ischemic stroke discharged on a statin over a 5 year period, 1,486 (23.7%) had a diagnosis of AF at discharge. Statin adherence rates, measured as percentage of days covered (PDC), averaged 85% (88% for AF patients and 84% for non-AF patients). We observed up to three years after the initial stroke, with an average of two years follow up. In multivariable survival models, after controlling for age, gender, race/ethnicity, and key medical comorbidities, higher statin adherence was found to strongly predict a reduced risk of recurrent ischemic stroke (Figure). In the second year post-stroke, the hazard ratio (HR) associated with a 10% increase in PDC was 0.93 (95% C.I. 0.89-097). The relationship between statin adherence and reduced stroke rates was similar in AF patients (HR 0.94, 95% C.I. 0.84-0.98) and non-AF patients (HR 0.93, 95% C.I. 0.88-0.98). These findings support the use of outpatient statins in all ischemic stroke patients, irrespective of stroke etiology (atherothrombotic vs. atrial fibrillation).
