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.

ObjectivesLow testosterone levels in men have been associated with cardiovascular risk factors and atherosclerosis and lately also an increased risk of both cardiovascular disease (CVD) and all-cause mortality. As arterial CVDs and venous thromboembolism (VTE) have been shown to share common risk factors, the purpose of the present study was to determine the impact of endogenous sex hormone levels on the incidence of VTE in a cohort of men.DesignA prospective, population-based study.MethodsSex hormone measurements were available in 1350 men, aged 50–84, participating in the Tromsø study in 1994–1995. First, lifetime VTE-events during the follow-up were registered up to September 1 2007.ResultsThere were 63 incident VTE-events (4.5 per 1000 person-years) during a mean of 10.4 years of follow-up. Age was significantly associated with increased risk of VTE; men 70 years or older had a 2.5-fold higher risk of VTE (HR 2.47, 95% CI 1.19–5.12), compared with those between 50 and 60 years of age. In age-adjusted analyses, endogenous sex hormones levels were not associated with risk of VTE; for each s.d. increase, hazards ratios (95% CI) were 1.06 (0.83–1.35) for total testosterone, 1.02 (0.79–1.33) for free testosterone, and 1.27 (0.94–1.71) for ln-estradiol. In dichotomized analyses comparing men in the lowest total and free testosterone quartile with men in the higher quartiles, hypoandrogenemia was not associated with risk of VTE.ConclusionsIn this population-based study of middle-aged and older men, endogenous sex hormone levels were not associated with 10-year risk of VTE.

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 Renal function is a major determinant of major adverse outcomes in patients with atrial fibrillation (AF). Scarce data are available about the impact of renal function trajectories and creatinine clearance (CrCl) temporal variability, on prognosis. Aim To evaluate the progression and impact of renal function impairment and variability on outcomes over a long-term follow-up observation in a cohort of anticoagulated AF patients. Methods We included warfarin-treated AF patients in SPORTIF trials with available creatinine clearance (according to Cockroft-Gault) at baseline and at least 4 evaluations throughout their follow-up. Patients with a BMI ≥45 kg/m2 were excluded from the analysis. Average successive variability (ASV) was used as measure of variability. Results Among 3665 original patients, 3366 (91.8%) were included in this analysis. Median [IQR] CHA2DS2-VASc score was 3 [2–4] and HAS-BLED was 3 [2–4]. At baseline, 876 (26.0%) patients had CKD (CrCl &lt;60 mL/min), with 14 (0.4%) patients having severe CKD (&lt;30 mL/min), with a mean (SD) CrCl of 86.7 (47.4) mL/min. Over a mean (SD) 577.1 (122.1) days of follow-up, a total of 521 new CKD cases were found with an overall incidence of 13.1 per 100 patient-years, with 91 new severe CKD cases (1.71 per 100 patient-years). Across follow-up, prevalence of CKD and severe CKD increased progressively (both p&lt;0.001) [Figure]. Mean (SD) AVS was −0.567 (±2.803) mL/min. According to AVS, patients were divided into quartiles: i) Q1: +34.012/+0.450; ii) Q2: +0.449/−0.443; iii) Q3: −0.443/−1.503; Q4: −1.505/−19.750. While no difference was found in stroke/systemic embolism, rate of major bleeding was higher in Q4 (4.5%) and Q1 (4.0%) than in other quartiles (Q2 2.5%, Q3 2.0%; p=0.009) as well as all-cause death (Q4: 6.7%; p=0.003 compared to other quartiles). A Cox multivariate adjusted model documented that AVS Q1 and Q4 were independently associated with a higher risk of major bleeding, while Q4 was associated with a higher risk of all-cause death (Table). Conclusion In a cohort of AF patients treated with warfarin, characterized by a progressive increase in the proportion with CKD and severe CKD, the largest reduction in CrCl throughout follow-up was associated to an increased risk of major bleeding and all-cause death.

The Impact

The aim of the present study was to construct a biological age score reflecting one’s physiologic capability and aging condition with respect to tooth loss over 10 y. From the follow-up to the population-based Study of Health in Pomerania (i.e., SHIP-2), 2,049 participants were studied for their baseline biomarker measures 10 y before (i.e., in SHIP-0). Metabolic and periodontal data were regressed onto chronological age to construct a score designated as “biological age.” For either sex separately, the impact of this individualized score was used to predict tooth loss in the follow-up cohort in comparison with each participant’s chronological age. Outcome data after 10 y with respect to tooth loss, periodontitis, obesity, and inflammation were shown to be better for biologically younger subjects than as expected by their chronological age, whereas for the older subjects, data were worse. Especially for tooth loss, a striking increase was observed in subjects whose biological age at baseline appeared to be higher than their chronological age. Biological age produced significantly better tooth loss predictions than chronological age ( P < 0.001). Areas under receiver operating characteristic curves for tooth loss of ≥3 teeth in men during follow-up were 0.811 and 0.745 for biological and chronological age, respectively. For women, these figures were 0.788 and 0.724. For total tooth loss, areas under the curve were 0.890 and 0.749 in men and 0.872 and 0.752 in women. Biological age combines various measures into a single score and allows identifying individuals at increased risk of tooth loss.

Abstract Background In the current study, we aimed to investigate the association of dietary inflammation scores (DIS) and lifestyle inflammation scores (LIS) with the risk of metabolic syndrome (MetS) in a prospective population-based study. Methods A total of 1625 participants without MetS were recruited from among participants of the Tehran Lipid and Glucose Study(2006–2008) and followed a mean of 6.1 years. Dietary data of subjects were collected using a food frequency questionnaire at baseline to determine LIS and DIS. Multivariable logistic regression models, were used to calculate the odds ratio (ORs) and 95 % confidence interval (CI) of MetS across tertiles of DIS and LIS. Results Mean ± SD age of individuals (45.8 % men) was 37.5 ± 13.4 years. Median (25–75 interquartile range) DIS and LIS for all participants was 0.80 (− 2.94, 3.64) and 0.48 (− 0.18, − 0.89), respectively. During the study follow-up, 291 (17.9 %) new cases of MetS were identified. Based on the age and sex-adjusted model, a positive association was found between LIS (OR = 7.56; 95% CI 5.10–11.22, P for trend < 0.001) and risk of MetS, however, the association of DIS and risk of MetS development was not statistically significant (OR = 1.30;95% CI 0.93–1.80, P for trend = 0.127). In the multivariable model, after adjustment for confounding variables, including age, sex, body mass index, physical activity, smoking, and energy intake, the risk of MetS is increased across tertiles of DIS (OR = 1.59; 95% CI 1.09–2.33, P for trend = 0.015) and LIS(OR = 8.38; 95% CI 5.51–12.7, P for trend < 0.001). Conclusions The findings of the current study showed that greater adherence to LIS and DIS, determined to indicate the inflammatory potential of diet and lifestyle, are associated with increased the risk of MetS.

SummaryWhether atrial fibrillation (AF) is associated with an increased risk of venous thromboembolism (VTE) remains controversial. From Longitudinal Health Insurance Database 2000 (LHID2000), we identified 11,458 patients newly diagnosed with AF. The comparison group comprised 45,637 patients without AF. Both cohorts were followed up to measure the incidence of deep-vein thrombosis (DVT) and pulmonary embolism (PE). Univariable and multivariable competing-risks regression model and Kaplan-Meier analyses with the use of Aelon-Johansen estimator were used to measure the differences of cumulative incidences of DVT and PE, respectively. The overall incidence rates (per 1,000 person-years) of DVT and PE between the AF group and non-AF groups were 2.69 vs 1.12 (crude hazard ratio [HR] = 1.92; 95 % confidence interval [CI] = 1.54-2.39), 1.55 vs 0.46 (crude HR = 2.68; 95 % CI = 1.97-3.64), respectively. The baseline demographics indicated that the members of the AF group demonstrated a significantly older age and higher proportions of comorbidities than non-AF group. After adjusting for age, sex, and comorbidities, the risks of DVT and PE remained significantly elevated in the AF group compared with the non-AF group (adjusted HR = 1.74; 95 %CI = 1.36-2.24, adjusted HR = 2.18; 95 %CI = 1.51-3.15, respectively). The Kaplan-Meier curve with the use of Aelon-Johansen estimator indicated that the cumulative incidences of DVT and PE were both more significantly elevated in the AF group than in the non-AF group after a long-term follow-up period (p<0.01). In conclusion, the presence of AF is associated with increased risk of VTE after a long-term follow-up period.

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.

Summary Background: There is an impression mostly from specialty clinics that patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolic disorders. Our aim was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) from a population-based database of IBD patients and, to compare the incidence rates to that of an age, gender and geographically matched population control group. Methods: IBD patients identified from the administrative claims data of the universal provincial insurance plan of Manitoba were matched 1:10 to randomly selected members of the general population without IBD by year, age, gender, and postal area of residence using Manitoba Health’s population registry. The incidence of hospitalization for DVT and PE was calculated from hospital discharge abstracts using ICD-9-CM codes 451.1, 453.x for DVT and 415.1x for PE. Rates were calculated based on person-years of follow-up for 1984-1997. Comparisons to the population cohort yielded age-adjusted incidence rate ratios (IRR). Rates were calculated based on person-years of follow-up (Crohn’s disease = 21,340, ulcerative colitis = 19,665) for 1984-1997. Results: In Crohn’s disease the incidence rate of DVT was 31.4/10,000 person-years and of PE was 10.3/10,000 person-years. In ulcerative colitis the incidence rates were 30.0/10,000 person-years for DVT and 19.8/10,000 person-years for PE. The IRR was 4.7 (95% CI, 3.5-6.3) for DVT and 2.9 (1.8-4.7) for PE in Crohn’s disease and 2.8 (2.1-3.7) for DVT and 3.6 (2.5-5.2) for PE, in ulcerative colitis. There were no gender differences for IRR. The highest rates of DVT and PE were seen among patients over 60 years old; however the highest IRR for these events were among patients less than 40 years. Conclusion: IBD patients have a threefold increased risk of developing DVT or PE.

The Relationship

The association between the cumulative hypertension burden and the development of atrial fibrillation (AF) is unclear. We aimed to investigate the relationship between hypertension burden and the development of incident AF. Using the Korean National Health Insurance Service database, we identified 3 726 172 subjects who underwent 4 consecutive annual health checkups between 2009 and 2013, with no history of AF. During the median follow-up of 5.2 years, AF was newly diagnosed in 22 012 patients (0.59% of the total study population; 1.168 per 1000 person-years). Using the blood pressure (BP) values at each health checkup, we determined the burden of hypertension (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg), stratified as 0 to 4 per the hypertension criteria. The subjects were grouped according to hypertension burden scale 1 to 4: 20% (n=742 806), 19% (n=704 623), 19% (n=713 258), 21% (n=766 204), and 21% (n=799 281). Compared with normal people, subjects with hypertension burdens of 1, 2, 3, and 4 were associated with an 8%, 18%, 26%, and 27% increased risk of incident AF, respectively. On semiquantitative analyses with further stratification of stage 1 (systolic BP of 130–139 mm Hg or diastolic BP of 80–89 mm Hg) and stage 2 (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg) hypertension, the risk of AF increased with the hypertension burden by up to 71%. In this study, both a sustained exposure and the degree of increased BP were associated with an increased risk of incident AF. Tailored BP management should be emphasized to reduce the risk of AF.
