Abstract Aims Trimethyllysine (TML) is involved in carnitine synthesis, serves as a precursor of trimethylamine N-oxide (TMAO) and is associated with cardiovascular events in patients with established coronary heart disease (CHD). We prospectively examined circulating TML as a predictor of all-cause and cardiovascular mortality in community-dwelling adults and patients with CHD. Methods and Results By Cox regression modelling, risk associations were examined in 6393 subjects in the community-based Hordaland Health Study (HUSK). A replication study was conducted among 4117 patients with suspected stable angina pectoris in the Western Norway Coronary Angiography Cohort (WECAC). During a mean follow-up of 10.5 years in the HUSK-cohort, 884 (13.8%) subjects died, of whom 287 from cardiovascular causes. After multivariable adjustments for traditional cardiovascular risk factors, the hazard ratio (HR) (95% CI) for all-cause mortality comparing the 4th vs. 1st TML-quartile was 1.66 (1.31-2.10, p < 0.001). Particularly strong associations were observed for cardiovascular mortality (HR [95% CI] 2.04 [1.32-3.15, p = 0.001]). Corresponding risk-estimates in the WECAC (mean follow-up of 9.8 years) were 1.35 [1.10-1.66, p = 0.004] for all-cause and 1.45 [1.06-1.98, p = 0.02] for cardiovascular mortality. Significant correlations between plasma TML and TMAO were observed in both cohorts (rs≥0.42, p < 0.001); however, additional adjustments for TMAO did not materially influence the risk associations, and no effect modification by TMAO was found. Conclusion Elevated TML-levels were associated with increased risk of all-cause and cardiovascular mortality both in subjects with and without established CHD.

Lv Dysfunction

ObjectivesSpeckle-tracking echocardiography enables detection of abnormalities in cardiac mechanics with higher sensitivity than conventional measures of left ventricular (LV) dysfunction and may provide insight into the pathogenesis of coronary heart disease (CHD). We investigated the relationship of LV longitudinal strain, LV early diastolic strain rate (SR) and left atrial (LA) reservoir strain with long-term CHD incidence in community-dwelling older adults.MethodsThe association of all three strain measures with incidence of non-fatal and fatal CHD (primary outcome of revascularisation, non-fatal and fatal myocardial infarction) was examined in the population-based Cardiovascular Health Study using multivariable Cox proportional hazards models. Follow-up was truncated at 10 years.ResultsWe included 3313 participants (mean (SD) age 72.6 (5.5) years). During a median follow-up of 10.0 (25th–75th percentile 7.7–10.0) years, 439 CHD events occurred. LV longitudinal strain (HR=1.25 per SD decrement, 95% CI 1.09 to 1.43) and LV early diastolic SR (HR=1.31 per SD decrement, 95% CI 1.14 to 1.50) were associated with a significantly greater risk of incident CHD after adjustment for potential confounders. By contrast, LA reservoir strain was not associated with incident CHD (HR=1.06 per SD decrement, 95% CI 0.94 to 1.19). Additional adjustment for biochemical and echocardiographic measures of myocardial stress, dysfunction and remodelling did not meaningfully alter these associations.ConclusionWe found an association between echocardiographic measures of subclinically altered LV mechanics and incident CHD. These findings inform the underlying biology of subclinical LV dysfunction and CHD. Early detection of asymptomatic myocardial dysfunction may offer an opportunity for prevention and early intervention.

Background: Poor carbohydrate quality has been associated with increased risk of coronary heart disease (CHD), however the association between the novel carbohydrate to fiber ratio and CHD is unknown. Objective: To prospectively examine the relationship between various carbohydrate quality measures, including the carbohydrate to fiber ratios, and incident CHD in US women. Methods: Dietary and lifestyle behavior data were prospectively collected (1984-2012) in 71,639 women of the Nurses’ Health Study at baseline and every 2-4 years. Participants were free of diabetes, cancer or cardiovascular disease at baseline. Cox regression was used to assess the relationship between carbohydrate quality measures and incident CHD. Results: After 24 years (1,905,240 person-years) of follow-up, we identified 3,267 cases of incident CHD. After adjusting for age, BMI, lifestyle and dietary variables, carbohydrate (RR=1.01, 95% CI: 0.89-1.14, P-trend=0.76), starch (RR=1.11, 95% CI: 0.97 - 1.27, P-trend=0.13) and total fiber intake (RR=0.89, 95% CI: 0.77 - 1.01, P-trend=0.23) were not associated with incident CHD, comparing extreme quintiles of intake. Cereal fiber intake was associated with reduced risk of CHD (RR=0.76, 95% CI: 0.67 - 0.85, P-trend < 0.0001), comparing extreme quintiles of intake, but fruit and vegetable fiber were not associated with incident CHD. In fully adjusted models, the carbohydrate to total fiber (RR=1.08, 95%CI: 0.96 - 1.22, P-trend=0.27) and the starch to total fiber ratios (RR=0.95, 95% CI: 0.84 - 1.08, P-trend=0.80) were not associated with incident CHD, but the carbohydrate to cereal fiber and the starch to cereal fiber ratios were associated with increased risk of CHD (RR=1.19, 95% CI: 1.06 -1.33, P-trend=0.002, and RR=1.23, 95% CI: 1.09-1.39, P-trend <0.0001, respectively), comparing extreme quintiles of intake. Conclusion: Dietary cereal fiber appears to be an important component of carbohydrate quality. The carbohydrate to cereal fiber and the starch to cereal fiber ratios, but not the carbohydrate to total fiber ratio, were associated with an increased risk of CHD.

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 Background In general, plant protein intake was inversely associated with mortality in studies in middle-aged adults. Our aim was to evaluate the long-term associations of animal and plant protein intake with mortality in older adults. Methods A prospective cohort study including 1,139 community-dwelling older adults (mean age 75 years, 56% women) living in Tuscany, Italy, followed for 20 years (InCHIANTI study) was analyzed. Dietary intake by food frequency questionnaires and clinical information were assessed five times during the follow-up. Protein intakes were expressed as percentages of total energy. Time-dependent Cox regression models adjusted for confounders were used to assess the association between plant and animal protein intake, and mortality. Results During the 20-years of follow up (mean: 12y), 811 deaths occurred (292 of cardiovascular- and 151 of cancer-related causes). Animal protein intake was inversely associated with all-cause (HR per 1% of total energy from protein increase, 95%CI: 0.96, 0.93-0.99) and cardiovascular mortality (HR per 1% of total energy from protein increase, 95%CI: 0.93, 0.87-0.98). Plant protein intake showed no association with any of the mortality outcomes, but an interaction with baseline hypertension was found for all-cause and cardiovascular mortality (p&lt;0.05). Conclusions Animal protein was inversely associated with all-cause and cardiovascular mortality in older adults. Further studies are needed to provide recommendations on dietary protein intake for older adults.

Aims: The present study aimed to investigate the prognostic role of derived neutrophil-to-lymphocyte ratio (dNLR) in patients with coronary heart disease (CHD) after PCI.Methods: A total of 3,561 post-PCI patients with CHD were retrospectively enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The patients (3,462) were divided into three groups according to dNLR tertiles: the first tertile (dNLR &lt; 1.36; n = 1,139), second tertile (1.36 ≥ dNLR &lt; 1.96; n = 1,166), and third tertile(dNLR ≥ 1.96; n = 1,157). The mean follow-up time was 37.59 ± 22.24 months. The primary endpoint was defined as mortality (including all-cause death and cardiac death), and the secondary endpoint was major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs).Results: There were 2,644 patients with acute coronary syndrome (ACS) and 838 patients with chronic coronary syndrome (CCS) in the present study. In the total population, the all-cause mortality (ACM) and cardiac mortality (CM) incidence was significantly higher in the third tertile than in the first tertile [hazard risk (HR) = 1.8 (95% CI: 1.2–2.8), p = 0.006 and HR = 2.1 (95% CI: 1.23–3.8), p = 0.009, respectively]. Multivariate Cox regression analyses suggested that compared with the patients in the first tertile than those in the third tertile, the risk of ACM was increased 1.763 times (HR = 1.763, 95% CI: 1.133–2.743, p = 0.012), and the risk of CM was increased 1.763 times (HR = 1.961, 95% CI: 1.083–3.550, p = 0.026) in the higher dNLR group during the long-term follow-up. In both ACS patients and CCS patients, there were significant differences among the three groups in the incidence of ACM in univariate analysis. We also found that the incidence of CM was significantly different among the three groups in CCS patients in both univariate analysis (HR = 3.541, 95% CI: 1.154–10.863, p = 0.027) and multivariate analysis (HR = 3.136, 95% CI: 1.015–9.690, p = 0.047).Conclusion: The present study suggested that dNLR is an independent and novel predictor of mortality in CHD patients who underwent PCI.

Blacks And Whites

Introduction: Abnormal plasma lipid levels associate with coronary heart disease (CHD) risk. Race interaction for these associations are not established. Hypothesis: We hypothesized that the association of HDL, LDL, and triglyceride with CHD is stronger in whites versus blacks. Methods: The REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort recruited 30,283 black and white individuals aged 45+ from the contiguous U.S. from 2003-7. Participants were followed until December 31, 2016 for CHD events (i.e., myocardial infarction or CHD death), participants with history of CHD at baseline were excluded. Cox regression models were used to assess the association between baseline lipids and incident CHD events adjusting for traditional cardiovascular risk factors. Results: With 23,894 participants (57.8% white and 58.4% female, mean age 64.11± 9.32), over a median 9.9 years of follow-up, 1,487 CHD events occurred (615 among blacks). Overall, higher total Cholesterol, LDL cholesterol, and triglycerides were associated with increased risk of CHD in both blacks and whites with no evidence of a race interaction (Table 1). For HDL, the point estimate was more protective in whites (HR 0.90) than in blacks (HR 0.98), but the interaction was non-significant (p=0.15). However, when HDL was stratified into clinical categories (<40, 40-59, and ≥60), the reduction in point estimates was maintained among whites (HR 1.00, 0.88, and 0.74) but not among blacks (HR 1.00, 1.31, and 1.19) for HDL <40, 40-59, and ≥60 respectively, p-interaction 0.01. Conclusion: Total cholesterol, LDL, and triglycerides predict CHD risk equally in blacks and whites in the REGARDS study, however there is heterogeneity in the protective effect by race, especially when traditional clinical categories are used. In whites, higher HDL is associated with reduced risk, whereas in blacks the association is not maintained. These findings suggest that HDL levels are a more viable metric for white than blacks to predict CHD risk.

Introduction: There are conflicting reports regarding whether daytime napping is a risk factor for cardiovascular events. The purpose of this study was to investigate the relationship between daytime napping and incident stroke within a community-based cohort study. Hypothesis: We assessed the hypothesis that the duration and the frequency of daytime napping may be associated with incident stroke. Methods: Participants without previous stroke were enrolled in the present prospective study from the Sleep Heart Health Study (registration number, NCT00005275). Daytime napping were assessed with a self-reported Sleep Habits Questionnaire. Duration of daytime napping was divided into the following categories: no naps, 0-30 min, 31-60 min, or >60 min. Frequency of naps were categorised as: no naps, 1-2 times/week, 3-4 times/week, 5-6 times/week, or daily. After combining nap duration and frequency, participants were further divided into groups with regular long naps (≥5 times per week and >30 min), regular short naps (≥5 times per week and ≤30 min), irregular naps or no naps. Subsequently, participants were followed up until the first stroke occurred between the date of the completed questionnaire and the final censoring date. Cox regression analysis was used to estimate the relationship between daytime napping and incident stroke. Results: The present study enrolled 4757 participants, of which 220 participants (4.6%) experienced incident stroke during an average follow-up of 10.6 years. There was a higher rate of stroke among participants taking longer and more frequent naps than others. Multivariate Cox regression analysis indicated that, when compared with participants with no naps, those with a nap duration of ≥60 min or of 31-60 min had a higher risk of stroke (HR, 2.182; 95% CI, 1.443-3.301; HR, 1.594; 95% CI, 1.003-2.531, respectively). Moreover, there was an increased risk of stroke among participants taking daily daytime naps (HR, 1.563; 95% CI, 1.059-2.307) or napping 5-6 times per week (HR, 1.548; 95% CI, 1.026-2.335) than those with no naps. And after combining nap duration and frequency, regular long naps and regular short naps were also associated with higher risk of incident stroke (HR, 1.903; 95% CI, 1.182-3.065; HR, 1.451; 95% CI, 1.010-2.084, respectively). Conclusions: In conclusion, daytime napping of long duration and high frequency may increase the risk of incident stroke in community. Modification of sleep habits may improve the life quality among those elderly community-based population.

Background Headache has not been established as a risk factor for dementia. The aim of this study was to determine whether any headache was associated with subsequent development of vascular dementia (VaD), Alzheimer’s disease (AD) or other types of dementia. Methods This prospective population-based cohort study used baseline data from the Nord-Trøndelag Health Study (HUNT 2) performed during 1995–1997 and, from the same Norwegian county, a register of cases diagnosed with dementia during 1997–2010. Participants aged ≥20 years who responded to headache questions in HUNT 2 were categorized (headache free; with any headache; with migraine; with nonmigrainous headache). Hazard ratios (HRs) for later inclusion in the dementia register were estimated using Cox regression analysis. Results Of 51,383 participants providing headache data in HUNT 2, 378 appeared in the dementia register during the follow-up period. Compared to those who were headache free, participants with any headache had increased risk of VaD ( n = 63) (multivariate-adjusted HR = 2.3, 95% CI 1.4–3.8, p = 0.002) and of mixed dementia (VaD and AD ( n = 52)) (adjusted HR = 2.0, 95% CI 1.1–3.5, p = 0.018). There was no association between any headache and later development of AD ( n = 180). Conclusion In this prospective population-based cohort study, any headache was a risk factor for development of VaD.

Abstract Background: Reduced renal function is an established risk factor for cardiovascular events. We compared 3 measures of renal function—serum cystatin C, serum creatinine, and calculated creatinine clearance—as predictors of subsequent cardiovascular events in a community-based population of elderly individuals. Methods: Comprehensive cardiovascular risk factor data were available for 1410 surviving participants of previous Busselton health surveys who were ≥60 years old. Hazard ratios for risk of incident coronary heart disease and cardiovascular disease over 10 years of follow-up were derived for each baseline measure of renal function by use of Cox regression. Results: All measures of renal function were significantly related to risks of morbidity and mortality from coronary heart disease and cardiovascular disease. There were 453 incident cardiovascular disease events; and the age- and sex-adjusted hazard ratios (95% CIs) were 1.34 (1.23–1.46), 1.32 (1.20–1.45), and 1.22 (1.06–1.41) per 1-SD deterioration in cystatin C, creatinine, and creatinine clearance, respectively. All 3 measures gave approximately the same age-adjusted relative risk estimates. After further adjustment for established cardiovascular risk factors, the relative risk estimates were all reduced but remained statistically significant (P &lt; 0.05). Cystatin C was not a significant predictor for cardiovascular disease after adjustment for creatinine clearance. Conclusions: In relation to predicting risk for coronary heart disease or cardiovascular disease over a 10-year follow-up in a community-based population of elderly subjects, there was no evidence that cystatin C was a better risk predictor than creatinine or creatinine clearance.
