Background and Purpose— To further improve preventive strategies against stroke, there is a need for epidemiological long-term studies. The study aimed at a prospective investigation of stroke determinants in the general male population. Methods— During a period of 48 years, from 50 to 98 years of age, a population-based sample of 854 men was followed using repeated medical examinations, lifestyle questionnaires, data from hospital records and the National Cause of Death Register. Results— Determinants of ischemic stroke were atrial fibrillation (hazard ratio [HR], 6.61; 95% CI, 4.47–9.77); mother dead from cardiovascular disease (HR, 1.53; 1.09–2.17); high education (HR, 0.81; 0.69–0.96); and high physical activity level during leisure time (HR, 0.68; 0.50–0.93). For hemorrhagic stroke heart rate (HR, 1.04; 1.01–1.06) and mother dead from stroke (HR, 3.56; 1.43–8.87) constituted an increased risk. Statistically significant determinants for all stroke were atrial fibrillation (HR, 5.34; 3.68–7.75); high diastolic blood pressure (HR, 1.02; 1.01–1.03); high body weight (HR, 0.96; 0.94–0.99); high educational level (HR, 0.79; 0.68–0.92); wide waist circumference (HR, 1.04; 1.01–1.07); smoking (HR, 1.25; 1.06–1.48); mother dead from cerebrovascular disease (HR, 1.43; 1.05–1.94); and diabetes mellitus (HR, 1.65; 1.02–2.68). Of all men diagnosed with atrial fibrillation, 88% had a stroke during follow-up. Conclusions— Atrial fibrillation was by far the strongest determinant of stroke during 48 years of follow-up in a male population sample followed until the age of 98 years. The results warrant improved prophylaxis through intense treatment of modifiable determinants.

Objective Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. Design It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. Results The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40–4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33–1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58–8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30–8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. Conclusions We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism.

Atrial fibrillation (AF) is considered a risk factor for dementia, especially in the elderly. However, the association between the two diseases is not well identified in different age subgroups. The association of incident AF with the development of dementia was assessed from 1 January 2005, to 31 December 2013, in 428,262 participants from a longitudinal cohort (the Korea National Health Insurance Service-Health Screening cohort). In total, 10,983 participants were diagnosed with incident AF during the follow-up period. The incidence of dementia was 11.3 and 3.0 per 1000 person-years in the incident-AF and without-AF groups, respectively. After adjustment for clinical variables, the risk of dementia was significantly elevated by incident AF, with a hazard ratio (HR) of 1.98 (95% confidence interval [CI]: 1.80–2.17, p < 0.001), even after censoring for stroke (HR: 1.74, 95% CI: 1.55–1.94, p < 0.001). The HRs of incident AF for dementia onset before the age of 65 (early-onset dementia) and for onset after the age of 65 (late-onset dementia) were 2.91 (95% CI: 1.93–4.41) and 1.67 (95% CI: 1.49–1.87), respectively. Younger participants with AF were more prone to dementia development than older participants with AF (p for trend < 0.001). AF was associated with an increased risk of both early- and late-onset dementia, independent of clinical stroke.

ObjectiveData on the contribution of ambulatory blood pressure (ABP) components to the risk of developing atrial fibrillation (AF) are limited. We prospectively tested the hypothesis that ABP may represent a potentially modifiable risk factor for the development of AF in a European population study.MethodsWe recorded daytime blood pressure (BP) in 3956 subjects randomly recruited from the general population in five European countries. Of these participants, 2776 (70.2%) underwent complete 24-hour ABP monitoring. Median follow-up was 14 years. We defined daytime systolic BP load as the percentage BP readings above 135 mm Hg. The incidence of AF was assessed from ECGs obtained at baseline and follow-up and from records held by general practitioners and/or hospitals.ResultsOverall, during 58 810 person-years of follow-up, 143 participants experienced new-onset AF. In adjusted Cox models, each SD increase in baseline 24 hours, daytime and night-time systolic BP was associated with a 27% (P=0.0056), 22% (P=0.023) and 20% (P=0.029) increase in the risk for incident AF, respectively. Conventional systolic BP was borderline associated with the risk of AF (18%; P=0.06). As compared with the average population risk, participants in the lower quartile of daytime systolic BP load (<3%) had a 51% (P=0.0038) lower hazard for incident AF, whereas in the upper quartile (>38%), the risk was 46% higher (P=0.0094).ConclusionsSystolic ABP is a significant predictor of incident AF in a population-based cohort. We also observed that participants with a daytime systolic BP load >38% had significantly increased risk of incident 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.

Abstract Background Minor ECG abnormalities, such as T-wave inversions, are frequently seen in clinical practice in asymptomatic patients. Its prognostic role is incompletely studied. We have previously reported an association between T-wave inversion, and all-cause mortality during lifetime. Purpose To study the prognostic prediction of new-onset of T-wave inversion in ECG recorded at various ages, in a male random population-based cohort in lifetime follow up. Methods Subjects from a random longitudinal, prospective, population-based study: “The study of men born in 1913” (n=854) were examined at 50-years of age and re-examined at 60, 67, 75 and 80 years, including a 12-lead ECG recording, classified according to the Minnesota code. Participants were followed until death or year 2015 (48 years follow-up), and data were obtained through the Cause of Death Register. Unadjusted and adjusted Cox proportional hazards models, producing an overall hazard ratio (HR), and flexible parametric models for survival data by Royston and Parmar, producing continuous HR over studied time, were applied for prediction of time to all-cause death and cardiovascular disease (CVD) death by the incident negative T-wave. Results An increased risk of all-cause and CVD death associated with negative T-waves was evident at the majority of observational ages in unadjusted analyses. After adjustment for other conditions (smoking, physical activity level, BMI, systolic blood pressure (BP), hypertension, BP medication, s-cholesterol, hematocrit, Q/QS patterns, and ST-junction/segment depression), a negative T-wave at 50 years of age was significantly associated with all-cause and CVD death, [HR 1.46 (95% CI 1.06–2.01), p=0.021, and HR 1.58 (95% CI 1.06–2.36), p=0.025], respectively. However, the HR of 1.58 for CVD death interacted significantly with time (p=0.034), with greater risk in the years adjacent to observation than for later follow-up (Figure, right panel). The corresponding adjusted analyses of a newly diagnosed negative T-wave appearing at 60, 67 and 75 years were not statistically significant for either of the two outcomes. However, an incident negative T-wave at 80 years of age was shown to have numerically higher overall impact, but not statistically significant for all-cause death [HR 1.52 (95% CI 0.80–2.86), p=0.20], but for CVD death [HR 2.41 (95% CI 1.03–5.66), p=0.043], with no significant interaction with time. Conclusion In this population cohort, a first time registered negative T-wave at 50 years carried a considerably increased risk of mortality, specifically CVD mortality, which cannot be explained by other cardiovascular risk factors. The risk was greatest in middle age, and weakened with increasing age. Our findings warrant verification in other cohorts. If an independent risk indication of negative T-wave at middle age is confirmed it could be a valuable adjunct in screening and cardiovascular risk assessment.

AbstractAlthough chronic kidney disease is known to increase the risk of atrial fibrillation (AF), the impact of the variability of renal function on the risk of incident AF is unknown. We aimed to evaluate the association between variability of renal function and the risk of developing AF among the general population. We evaluated a total of 3,551,249 adults who had three annual health check-ups provided by the National Health Insurance Service. The variability of renal function was defined as GFR-VIM, which is variability independent of the mean (VIM) of creatinine-based estimated glomerular filtration rate (eGFR). The study population was divided into four groups (Q1-4) based on the quartiles of GFR-VIM, and the risks of incident AF by each group were compared. During a mean of 3.2 ± 0.5 years follow-up, incident AF occurred in 15,008 (0.42%) subjects. The incidence rates of AF increased from Q1 to Q4 (0.98, 1.42, 1.27, and 1.63 per 1,000 person-years, respectively). Adjusting with multiple variables, Q4 showed an increased risk of incident AF compared to Q1 (hazard ratio (HR) 1.125, 95% confidence interval (CI) 1.071–1.181). Variability of serum creatinine or other definitions of variability showed consistent results. On subgroup analyses, Q4 in males or those with a decreasing trend of eGFR had significantly increased risks of incident AF compared to Q1 (HR 1.127, 95% CI 1.082–1.175; and HR 1.115, 95% CI 1.059–1.173, respectively). High variability of eGFR was associated with an increased risk of incident AF, particularly in males or those with decreasing trends of eGFR during follow-up.

Background Limited population‐based data on the (sex‐specific) link between subclinical measures of peripheral atherosclerosis and new‐onset atrial fibrillation (AF) exist. Methods and Results Subclinical measures of peripheral atherosclerosis including carotid intima‐media thickness (cIMT), carotid plaque, and ankle‐brachial index (ABI) were assessed at baseline and follow‐up examinations. A total of 12 840 participants free of AF at baseline from the population‐based Rotterdam Study were included. Cox proportional hazards models and joint models, adjusted for cardiovascular risk factors, were used to determine the associations between baseline and longitudinal measures of cIMT, carotid plaque, and ABI with new‐onset AF. During a median follow‐up of 9.2 years, 1360 incident AF cases occurred among 12 840 participants (mean age 65.2 years, 58.3% women). Higher baseline cIMT (fully‐adjusted hazard ratio [HR], 95% CI, 1.81, 1.21–2.71; P =0.0042), presence of carotid plaque (fully‐adjusted HR, 95% CI, 1.19, 1.04–1.35; P =0.0089), lower ABI (fully‐adjusted HR, 95% CI, 1.57, 1.14–2.18; P =0.0061) and longitudinal measures of higher cIMT (fully‐adjusted HR, 95% CI, 2.14, 1.38–3.29; P =0.0021), presence of carotid plaque (fully‐adjusted HR, 95% CI, 1.61, 1.12–2.43; P =0.0112), and lower ABI (fully‐adjusted HR, 95% CI, 4.43, 1.83–10.49; P =0.0007) showed significant associations with new‐onset AF in the general population. Sex‐stratified analyses showed that the associations for cIMT, carotid plaque, and ABI were mostly prominent among women. Conclusions Baseline and longitudinal subclinical measures of peripheral atherosclerosis (carotid atherosclerosis, and lower extremity peripheral atherosclerosis) were significantly associated with an increased risk of new‐onset AF, especially among women.

Abstract Background New-onset postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery, but the prognostic implications are not settled. In contrast to previous reports, a recent Danish study in coronary bypass surgery (CABG) patients (Butt et al. JAMA Cardiol 2018) did not show any increased risk for thromboembolic complications in POAF patients. Purpose To compare long-term outcome in patients with vs. without POAF after CABG. Methods All CABG patients in Sweden 2005–2015 (n=38040) were included in a retrospective population-based cohort study. Data from the SWEDEHEART registry, the National Patient Registry and the National Population Registry were merged. POAF was defined as any new-onset atrial fibrillation (AF) episode up to the 30thpostoperative day. Inverse Probability Treatment Weighting (IPTW) adjusted Cox regression models were used to compare outcome variables after the first 30 postoperative days until the end of follow-up (median 5 years, range 0–10). The models were adjusted for age, gender, CHA2DS2-VASc score, co-morbidity, and medications. Results The mean age of the entire cohort was 68 years, 79% were men and 90% had a CHA2DS2-VASc score ≥2. The incidence of POAF was 28.5% (10845/38040). During follow-up POAF, patients had a significantly higher adjusted risk for all-cause mortality [Hazard Ratio (HR) 1.16 (95% CI 1.09–1.24)], ischemic stroke [HR 1.19 (1.09–1.30)], transient ischemic attack [HR 1.17 (1.03–1.33)], pulmonary embolism [HR 1.24 (1.01–1.54)], myocardial infarction [HR 1.14 (1.04–1.25)], heart failure hospitalizations [HR.1.46 (1.35–1.59)] and recurrent AF [HR 4.33 (4.09–4.65)]. Conclusions POAF was in this comparatively large study associated with increased risk for mortality and morbidity during long-term follow-up after CABG and is hence not a trivial complication.
