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.

Abstract Background Thoracic aortic diameters have been associated with cardiovascular risk factors and atherosclerosis. However, limited evidence regarding the role of thoracic aortic diameters as risk markers for major cardiovascular outcomes among women and men exist. Purpose To evaluate the independent associations between crude and indexed ascending and descending aortic (AA and DA) diameters with major cardiovascular outcomes among women and men and to provide optimal cutoff values associated with increased cardiovascular risk. Methods and results 2178 women and men ≥55 years from the prospective population-based Rotterdam Study underwent multi-detector CT scan of thorax. Crude diameters of the AA and DA were measured and indexed by height, weight, body surface area (BSA) and body mass index (BMI). Incidence of stroke, coronary heart disease (CHD), heart failure (HF), cardiovascular and all-cause mortality were evaluated during 13 years of follow-up. Weight-, BSA-, or BMI-indexed AA diameters showed significant associations with total or cardiovascular mortality in both sexes and height-indexed values showed association with HF in women. Crude AA diameters were associated with stroke in men and HF in women. For DA, crude and almost all indexed diameters showed significant associations with either stroke, HF, cardiovascular or total mortality in women. Only weight-, BSA- and BMI-indexed values were associated with total mortality in men. For crude DA diameter, the risk for stroke increased significantly at the 75th percentile among men while the risks for HF and cardiovascular mortality increased at the 75th and 85th percentiles respectively in women. Conclusions Our study suggests a role for descending thoracic aortic diameter as a marker for increased cardiovascular risk, in particular for stroke, heart failure and cardiovascular mortality among women. The cut points for increased risk for several of cardiovascular outcomes were below the 95th percentile of the distribution of aortic diameters.

Abstract Background Data on prevalence and associated prognosis of repolarization abnormalities among hypertensive patients are limited. Purpose We investigated the presence and extent of ST-segment and T-wave changes in a hypertensive population and their predictive ability for cardiovascular disease. Methods We studied 1851 white Caucasian hypertensive patients (age 58±12 years, 51%females) without a history of cardiovascular disease for a mean period of 5.3±3.4 years. At the baseline examination, all patients underwent standard 12-lead electrocardiography. T-wave inversion (TWI) was defined as T-wave deflection ≥−0.1 mV in ≥2 contiguous leads,unless associated with bundle branch block. Anterior, lateral or inferior TWI was defined as TWIin leads V2-V4 or V5,V6, I, AVL or II, aVF respectively. Thedepth in millimeters of TWI in each lead was recorded and the maximum depth per location was calculated. ST depression was defined as ≥1mm in depth in two or more contiguous leads.During follow-up, patients underwent clinic visits at least yearly for management of hypertension and risk factors. The outcome studied was theincidence of cardiovascular morbidity set as the composite of non-fatal coronary artery disease and stroke. Results In the entire population, prevalence of TWI was 3.8%, of which 39% presented withanterior TWI, 73% withlateral TWI and 11% with inferior TWI. ST depression was observed in 3.6% of patients (anterior in 0.8%, inferior in 0.9% and lateral in 2.6%). Incidence of the composite endpoint during follow-up was 4%. Cox regression analysis revealed that presence of TWI was associated with a significantly greater risk for cardiovascular events (HR: 2.6, 95% CI: 1.1–5.9, p=0.025). The association was stronger for lateral TWI (HR: 3.3, 95%: CI: 1.34–8.30, p=0.01) compared to other locations. In multivariate models controlling for standard confounders these associations were overall sustained. Depth of TWI and presence of ST depression were not associated with cardiovascular risk. Conclusions Among hypertensive patients without cardiovascular disease, TWI is infrequent but significantly associated with future cardiovascular events.Lateral TWI carries the worse prognosis Funding Acknowledgement Type of funding source: None

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.

BackgroundGenetic vulnerability to coronary heart disease (CHD) is well established, but little is known whether these effects are mediated or modified by equally well-established social determinants of CHD. We estimate the joint associations of the polygenetic risk score (PRS) for CHD and education on CHD events.MethodsThe data are from the 1992, 1997, 2002, 2007 and 2012 surveys of the population-based FINRISK Study including measures of social, behavioural and metabolic factors and genome-wide genotypes (N=26 203). Follow-up of fatal and non-fatal incident CHD events (N=2063) was based on nationwide registers.ResultsAllowing for age, sex, study year, region of residence, study batch and principal components, those in the highest quartile of PRS for CHD had strongly increased risk of CHD events compared with the lowest quartile (HR=2.26; 95% CI: 1.97 to 2.59); associations were also observed for low education (HR=1.58; 95% CI: 1.32 to 1.89). These effects were largely independent of each other. Adjustment for baseline smoking, alcohol use, body mass index, igh-density lipoprotein (HDL) and total cholesterol, blood pressure and diabetes attenuated the PRS associations by 10% and the education associations by 50%. We do not find strong evidence of interactions between PRS and education.ConclusionsPRS and education predict CHD events, and these associations are independent of each other. Both can improve CHD prediction beyond behavioural risks. The results imply that observational studies that do not have information on genetic risk factors for CHD do not provide confounded estimates for the association between education and CHD.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p<0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p<0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.

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.

ObjectiveGastro-oesophageal reflux disease (GORD) is a common comorbidity among patients with rheumatoid arthritis (RA). While GORD has been attributed to the antirheumatic medications, no studies of human cohorts have investigated a link between GORD and RA. This study investigates whether GORD is associated with a subsequent RA diagnosis over a 5-year follow-up using a population-based dataset.SettingTaiwanParticipantsWe used data from the Taiwan Longitudinal Health Insurance Database. The study group consisted of 13 645 patients with an ambulatory claim showing a GORD diagnosis. We used propensity score matching to select 13 645 comparison patients (one per study patient with GORD).InterventionWe tracked each patient’s claims over a 5-year period to identify those who subsequently received a diagnosis of RA. Cox proportional hazard (PH) regression modelling was used for analysis.ResultsOver 5-year follow-up, RA incidence rate per 1000 person-years was 2.81 among patients with GORD and 0.84 among the comparison group. Cox PH modelling showed that GORD was independently associated with a 2.84-fold increased risk of RA (95% CI 2.09 to 3.85) over 5-year follow-up, after adjusting for the number of ambulatory care visits within the year following the index date (to mitigate surveillance bias).ConclusionsWe observed that GORD might associate with subsequent RA occurrence. Because current treatment guidelines for RA emphasise early diagnosis and prompt treatment, the observed association between GORD and RA may help acquaint clinicians to patients with GORD with higher RA risk and facilitate early diagnosis and treatment.

Abstract Sensory impairment (SI) is common among older adults, and it is an increasingly important public health challenge as the population ages. We evaluated the association between SI and incident disability-related cessation of employment in older adults using the population-based Health and Retirement Study. Participants employed in 2006 completed biennial interviews until self-reported incident disability-related cessation of employment. Participants were censored at loss to follow-up, retirement, or 2018. Participants rated their vision and hearing, using eyeglasses or hearing aids if applicable, on a Likert scale (poor, fair, good, very good, excellent). SI was defined as poor or fair ability, and SI was categorized as neither SI (NSI), vision impairment alone (VI), hearing impairment alone (HI), and dual SI (DSI). Cox proportional hazard regression assessed the association between SI and incident disability-related cessation of employment, adjusting for demographic and health covariates. Overall, 4726 participants were included: 421 (8.9%) were with VI, 487 (10.3) with HI, and 203 (4.3%) with DSI. Mean age was 61.0 ± 6.8 years, 2488 (52.6%) were women, and 918 (19.4) were non-White. In the fully adjusted model, incident disability-related cessation of employment over the 12-year follow-up period was higher in VI (Hazard Ratio (HR)=1.30, 95% confidence interval (CI)=0.92, 1.85), HI (HR=1.60, CI=1.16, 2.22), and DSI (HR=2.02, CI=1.38, 2.96). These findings indicate that employed older adults with SI are at increased risk of incident disability-related cessation of employment, and that older adults with DSI are particularly vulnerable. Addressing SI in older adults may lengthen their contribution to the workforce.

Ckd Stage

We investigated the association between dietary micronutrient intakes and the risk of chronic kidney disease (CKD) in the Ansan-Ansung study of the Korean Genome and Epidemiologic Study (KoGES), a population-based prospective cohort study. Of 9079 cohort participants with a baseline estimate glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 and a urine albumin to creatinine ratio (UACR) <300 mg/g and who were not diagnosed with CKD, we ascertained 1392 new CKD cases over 12 year follow-up periods. The risk of CKD according to dietary micronutrient intakes was presented using hazard ratios (HRs) and 95% confidence intervals (95% CIs) in a full multivariable Cox proportional hazard models, adjusted for multiple micronutrients and important clinico-epidemiological risk factors. Low dietary intakes of phosphorus (<400 mg/day), vitamin B2 (<0.7 mg/day) and high dietary intake of vitamin B6 (≥1.6 mg/day) and C (≥100 mg/day) were associated with an increased risk of CKD stage 3B and over, compared with the intake at recommended levels (HR = 6.78 [95%CI = 2.18–21.11]; HR = 2.90 [95%CI = 1.01–8.33]; HR = 2.71 [95%CI = 1.26–5.81]; HR = 1.83 [95%CI = 1.00–3.33], respectively). In the restricted population, excluding new CKD cases defined within 2 years, an additional association with low folate levels (<100 µg/day) in higher risk of CKD stage 3B and over was observed (HR = 6.72 [95%CI = 1.40–32.16]). None of the micronutrients showed a significant association with the risk of developing CKD stage 3A. Adequate intake of micronutrients may lower the risk of CKD stage 3B and over, suggesting that dietary guidelines are needed in the general population to prevent CKD.
