Incidence Of Coronary Heart Disease Research Articles

Can change in phase angle predict the risk of morbidity and mortality during an 18-year follow-up period? A cohort study among adults.

Phase angle (PhA, degrees), measured via bioimpedance (BIA, 50 kHz), is an index that has been used as an indicator of nutritional status and mortality in several clinical situations. This study aimed to determine the relationship between 6-year changes in PhA and total mortality as well as the risk of incident morbidity and mortality from cardiovascular disease (CVD) and coronary heart disease (CHD) during 18 years of follow-up among otherwise healthy adults. A random subset (n = 1,987) of 35-65 years old men and women was examined at the baseline in 1987/1988 and 6 years later in 1993/1994. Measures included weight, height, and whole-body BIA, from which PhA was calculated. Information on lifestyle was obtained through a questionnaire. The associations between 6-year PhA changes (ΔPhA) and incident CVD and CHD were assessed by Cox proportional hazard models. The median value of ΔPhA was used as the reference value. The hazard ratio (HR) model and confidence intervals (CIs) of incident CVD and CHD were used according to the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of ΔPhA. During 18 years of follow-up, 205 women and 289 men died. A higher risk of both total mortality and incident CVD was present below the 50th percentile (Δ = -0.85°). The highest risk was observed below the 5th percentile (ΔPhA = -2.60°) in relation to total mortality (HR: 1.55; 95% CI: 1.10-2.19) and incident CVD (HR: 1.52; 95% CI: 1.16-2.00). The larger the decrease in PhA, the higher the risk of early mortality and incident CVD over the subsequent 18 years. PhA is a reliable and easy measure that may help identify those apparently healthy individuals who may be at increased risk of future CVD or dying prematurely. More studies are needed to confirm our results before it can be definitively concluded that PhA changes can improve clinical risk prediction.

Volatile Hydrocarbon Exposures and Incident Coronary Heart Disease Events: Up to Ten Years of Follow-up among Deepwater Horizon Oil Spill Workers.

During the 2010 Deepwater Horizon (DWH) disaster, response and cleanup workers were potentially exposed to toxic volatile components of crude oil. However, to our knowledge, no study has examined exposure to individual oil spill-related chemicals in relation to cardiovascular outcomes among oil spill workers. Our aim was to investigate the association of several spill-related chemicals [benzene, toluene, ethylbenzene, xylene, n-hexane (BTEX-H)] and total hydrocarbons (THC) with incident coronary heart disease (CHD) events among workers enrolled in a prospective cohort. Cumulative exposures to THC and BTEX-H across the cleanup period were estimated via a job-exposure matrix that linked air measurement data with self-reported DWH spill work histories. We ascertained CHD events following each worker's last day of cleanup work as the first self-reported physician-diagnosed myocardial infarction (MI) or a fatal CHD event. We estimated hazard ratios (HR) and 95% confidence intervals for the associations of exposure quintiles (Q) with risk of CHD. We applied inverse probability weights to account for bias due to confounding and loss to follow-up. We used quantile g-computation to assess the joint effect of the BTEX-H mixture. Among 22,655 workers with no previous MI diagnoses, 509 experienced an incident CHD event through December 2019. Workers in higher quintiles of each exposure agent had increased CHD risks in comparison with the referent group (Q1) of that agent, with the strongest associations observed in Q5 (range of ). However, most associations were nonsignificant, and there was no evidence of exposure-response trends. We observed stronger associations among ever smokers, workers with education, and workers with body mass index . No apparent positive association was observed for the BTEX-H mixture. Higher exposures to volatile components of crude oil were associated with modest increases in risk of CHD among oil spill workers, although we did not observe exposure-response trends. https://doi.org/10.1289/EHP11859.

Marital status and long-term cardiovascular risk in general population (Gubbio, Italy)

To investigate whether marital status is associated to long-term major fatal and non-fatal cardiovascular events in men and women from the Gubbio Population Study. The incidence of cardiovascular disease (CVD), including stroke and coronary heart disease (CHD) and CVD death together with all-cause mortality were analyzed. The analysis included 2832 persons (44% men, 54 ± 11 years old). Marital status was defined at entry as married (married or living conjugally) versus unmarried subjects (widowed, separated, divorced or single). Married and unmarried subjects did not differ concerning socio-demographic, anthropometric and biological variables at baseline. Over 191 months median follow-up, the incidence of CHD was lower among married versus unmarried women [HR: 0.63 (95% CI 0.41–0.96)] only; the same was true for CHD mortality [HR: 0.43 (95% CI 0.22–0.84)] and all-cause mortality [HR: 0.75 (95% CI 0.59–0.96)] independently of traditional risk factors (age, SBP, total and HDL cholesterol, cigarette smoke and BMI). In men, marital status was not associated to any of the investigated outcomes. In primary care, marital status should be investigated as it can be associated with long-term CHD and all-cause incidence and mortality risks among women.

High miR-126-3p levels associated with cardiovascular events in a general population

BackgroundEndothelial dysfunction is a forerunner of atherosclerosis, leading to cardiovascular disease, and albuminuria is a marker of endothelial dysfunction. Circulating levels of microRNAs are emerging as potential biomarkers for cardiovascular disease. Here we estimate the predictive value of a plasma microRNAs signature associated with albuminuria in the incidence of cardiovascular events. MethodsPlasma microRNAs quantified in hypertensive patients by next generation sequencing were validated in a cohort of patients and controls by real-time quantitative PCR. The microRNAs found to be associated with albuminuria were analysed for their prognostic value in predicting cardiovascular events incidence on a retrospective, population-based study (Hortega Study), using Cox proportional hazard models. ResultsA plasma microRNA profile was identified in the discovery cohort (n = 48) associated with albuminuria and three microRNAs (miR-126–3p, miR-1260b and miR-374a-5p) were confirmed in the validation cohort (n = 98). The microRNA signature discriminates urinary albumin excretion at baseline (n = 1025), and predicts the incidence of cardiovascular events and coronary heart disease and stroke in a general population retrospective study within a 14-year follow-up (n = 926). High miR-126–3p levels were associated with a shorter time free of both cardiovascular events (HR=1.48, (1.36–1.62), p < 0.0001), as well as coronary artery disease and stroke combined (HR=2.49, (2.19–2.83), p < 0.0001). ConclusionsAn increased plasma microRNAs profile was identified in hypertensive patients with albuminuria. Increased miR-126–3p suggest it may serve as a prognostic marker for cardiovascular events in a long-term general population. Further studies will assess the potential role of miR-126–3p as a guide for the status of endothelial dysfunction.

Genetic Risk Score for Prediction of Coronary Heart Disease in the Korean Genome and Epidemiology Study.

Using a genetic risk score (GRS) to predict coronary heart disease (CHD) may detect disease earlier. The current study aims to assess whether GRS is associated with CHD incidence and whether it is clinically useful for improving prediction using traditional risk factors (TRFs) as well as family history. Data from a total of 48,941 participants in the Korean Genome and Epidemiology Study were analyzed in the current study. The weighted GRS was constructed using 55 single-nucleotide polymorphisms based on published genome-wide association studies. The association of GRS with incident CHD was analyzed using Cox proportional hazard model. Discrimination and reclassification were assessed to demonstrate the clinical utility of GRS. The analyses were performed separately by sex. After adjusting for family history and TRFs, GRS was significantly associated with CHD incidence in men; compared to the low GRS group, men in the high GRS group had a 2.07-fold increased risk of CHD (95% confidence interval [CI]: 1.51-2.85). In men, the combination of TRFs, family history, and GRS had better performance than TRFs alone (C statistics for TRF-only model, 0.66, 95% CI, 0.64-0.69; C statistics for combination model, 0.68, 95% CI, 0.65-0.71; category-free reclassification index, 15%). In women, however, there was no significant association between GRS and CHD and no improvement between models. GRS was associated with CHD incidence and contributed to a small improvement of CHD prediction in men. The potential clinical use of GRS may not outweigh the value of family history.

Short sleep duration associated with the incidence of cardio-cerebral vascular disease: a prospective cohort study in Shanghai, China

ImportanceSleep duration plays an important role in predicting CCVD incidence, and have implications for reducing the burden of CCVD. However, the association between sleep duration and predicted cardio-cerebral vascular diseases (CCVD) risk remains to be fully understood.ObjectiveTo investigate the effects of sleep duration on the development of CCVD among Chinese community residents.DesignA prospective cohort study. The baseline survey was conducted from January 2013 to July 2013. The cohort has been followed until December 31, 2016 using a combination of in-person interviews and record linkages with the vital registry of Pudong New Area, Shanghai, China.SubjectsA total of 8245 Chinese community residents were initially enrolled in the cohort. Of those, 6298 underwent the follow-up examination.ExposureSelf-reported sleep duration and sleep quality were obtained via the questionnaire. Sleep duration was divided into five categories: ≤5, 6, 7, 8, or ≥ 9 h per day.Main Outcome(s) and Measure(s)CCVD, Coronary heart disease (CHD) and Stroke occurrence, Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated using Fine-Gray proportional subdistribution hazards models.ResultsDuring a median follow-up of 3.00 years (IQR 2.92–3.08), we observed 370 participants have had incident CCVD events, of whom 230 had CHDs, 169 had strokes, and 29 had both. After adjustment for relevant confounders, short sleepers (≤ 5 h) had 83% higher risk of total CCVD incidence (HR: 1.83; 95% CI: 1.32–2.54), 82% higher risk of CHD incidence (HR: 1.82; 95% CI: 1.21–2.75), and 82% higher risk of stroke incidence (HR: 1.82; 95% CI: 1.12–2.98) in contrast to the reference group (7 h). Some of these U-shaped relationships varied by age, and were more pronounced in individuals aged < 65 years. Individuals who slept ≤ 5 h per day with baseline hypertension had the highest risk of CCVD incidence (HR: 3.38, 95% CI 2.08–5.48), CHD incidence (HR: 3.11, 95% CI 1.75–5.53), and stroke incidence (HR: 4.33, 95% CI 1.90–9.86), compared with those sleep 7 h and without baseline hypertension.ConclusionsShort sleep duration is independently associated with greater incidence of CCVD, CHD and stroke.

Healthy lifestyle, DNA methylation age acceleration, and incident risk of coronary heart disease

BackgroundDNA methylation clocks emerged as a tool to determine biological aging and have been related to mortality and age-related diseases. Little is known about the association of DNA methylation age (DNAm age) with coronary heart disease (CHD), especially in the Asian population.ResultsMethylation level of baseline blood leukocyte DNA was measured by Infinium Methylation EPIC BeadChip for 491 incident CHD cases and 489 controls in the prospective China Kadoorie Biobank. We calculated the methylation age using a prediction model developed among Chinese. The correlation between chronological age and DNAm age was 0.90. DNA methylation age acceleration (Δage) was defined as the residual of regressing DNA methylation age on the chronological age. After adjustment for multiple risk factors of CHD and cell type proportion, compared with participants in the bottom quartile of Δage, the OR (95% CI) for CHD was 1.84 (1.17, 2.89) for participants in the top quartile. One SD increment in Δage was associated with 30% increased risk of CHD (OR = 1.30; 95% CI 1.09, 1.56; Ptrend = 0.003). The average number of cigarette equivalents consumed per day and waist-to-hip ratio were positively associated with Δage; red meat consumption was negatively associated with Δage, characterized by accelerated aging in those who never or rarely consumed red meat (all P < 0.05). Further mediation analysis revealed that 10%, 5% and 18% of the CHD risk related to smoking, waist-to-hip ratio and never or rarely red meat consumption was mediated through methylation aging, respectively (all P for mediation effect < 0.05).ConclusionsWe first identified the association between DNAm age acceleration and incident CHD in the Asian population, and provided evidence that unfavorable lifestyle-induced epigenetic aging may play an important part in the underlying pathway to CHD.

The mediation effects of metabolic and immune–inflammation factors on the depression–premature coronary heart disease association

BackgroundAccumulated evidence confirmed depression was positively associated with coronary heart disease (CHD). But evidence of the association between depression and premature CHD is still unknown. ObjectivesTo explore the association between depression and premature CHD, and to investigate whether and to what extent the association is mediated by metabolic factors and systemic immune–inflammation index (SII). MethodsIn this large population–based cohort study based on the UK Biobank, 176,428 CHD–free (mean age: 52.70) adults were followed up for 15 years to detect incident premature CHD. Depression and premature CHD (mean age: female, 54.53; male, 48.13) were ascertained from self–report data and linked hospital–based clinical diagnosis. Metabolic factors included central obesity, hypertension, dyslipidemia, hypertriglyceridemia, hyperglycemia, and hyperuricemia. Systemic inflammation was evaluated by calculating SII, which equals platelet count (/L) × neutrophil count (/L) / lymphocyte count (/L). Data were analyzed using Cox proportional hazards models and generalized structural equation model (GSEM). ResultsDuring follow–up (median: 8.0 years, interquartile range: 4.0 to 14.0 years), 2990 participants developed premature CHD (1.7 %). The adjusted hazard ratio (HR) and 95 % confidence interval (CI) of premature CHD related to depression were 1.72 (1.44–2.05). The association between depression and premature CHD was 32.9 % mediated by comprehensive metabolic factors (β = 0.24, 95 % CI: 0.17–0.32) and 2.7 % by SII (β = 0.02, 95 % CI = 0.01–0.04), respectively. Concerning metabolic factors, the strongest indirect association was for central obesity, accounting for 11.0 % of the association between depression and premature CHD (β = 0.08, 95 % CI: 0.05–0.11). ConclusionsDepression was associated with an increased risk of premature CHD. Our study provided evidence that metabolic and inflammatory factors might play a mediating role in the association between depression and premature CHD, especially central obesity.

Height, social position and coronary heart disease incidence: the contribution of genetic and environmental factors

Determinants of coronary heart disease among adults: a case-control study

BackgroundAccording to recent World Health Organization data, coronary heart disease (CHD) remains the leading cause of death worldwide. Although the risk factors of this disease are well known, the strength of these factors varies in different populations. The aim of the study was to assess the determinants of CHD in Indonesian adults aged 25 years and over. MethodsA case–control study was carried out involving 592 subjects aged 25 years and over (444 controls and 148 cases). Participants were interviewed using validated questionnaires. Physical examinations and supporting examinations were conducted. The Chi square test, Fisher’s exact test, and independent t test were used to analyze the data. To determine independent predictors of CHD, the odds ratio (OR) was determined via the multiple logistic regressions test. ResultsThe CHD subjects (case group) showed higher blood sugar and systolic pressure than non-CHD subjects (controls), with mean fasting blood sugar of 92.53±27.05 mg/dL vs 88.29 ±23.43 mg/dL (p=0.038), 2-hour postprandial blood sugar of 133.15±65.09 mg/dL vs 120.87±44.60 mg/dL (p=0.000), and systolic blood pressure of 89±27.62 mmHg vs 129.98±10.58 mmHg (p=0.002). The logistic regression analysis in the case group showed that higher education (college) had a 2.32-fold greater effect (95% CI. 1.01-5.35) on CHD incidence compared to the control group. ConclusionsThis study has demonstrated that the most frequent risk factor for CVD in adults aged 25 years and over is higher education. Control and prevention of CHD need to be done with regular control of blood sugar levels and blood pressure to stabilize them within normal limits.

Racial Differences in Fatal Out-of-Hospital Coronary Heart Disease and the Role of Income in the Atherosclerosis Risk in Communities Cohort Study (1987 to 2017)

Black patients have higher incident fatal coronary heart disease (CHD) rates than do their White counterparts. Racial differences in out-of-hospital fatal CHD could explain the excess risk in fatal CHD among Black patients. We examined racial disparities in in- and out-of-hospital fatal CHD among participants with no history of CHD, and whether socioeconomic status might play a role in this association. We used data from the ARIC (Atherosclerosis Risk in Communities) study, including 4,095 Black and 10,884 White participants, followed between 1987 and 1989 until 2017. Race was self-reported. We examined racial differences in in- and out-of-hospital fatal CHD with hierarchical proportional hazard models. We then examined the role of income in these associations, using Cox marginal structural models for a mediation analysis. The incidence of out-of-hospital and in-hospital fatal CHD was 1.3 and 2.2 in Black participants, and 1.0 and 1.1 in White participants, respectively, per 1,000 person-years. The gender- and age-adjusted hazard ratios comparing out-of-hospital and in-hospital incident fatal CHD in Black with that in White participants were 1.65 (1.32 to 2.07) and 2.37 (1.96 to 2.86), respectively. The income-controlled direct effects of race in Black versus White participants decreased to 1.33 (1.01 to 1.74) for fatal out-of-hospital and to 2.03 (1.61 to 2.55) for fatal in-hospital CHD in Cox marginal structural models. In conclusion, higher rates of fatal in-hospital CHD in Black participants than in their White counterparts likely drive the overall racial differences in fatal CHD. Income largely explained racial differences in both fatal out-of-hospital CHD and fatal in-hospital CHD.

Hypertensive retinopathy and cardiovascular disease risk: 6 population-based cohorts meta-analysis

BackgroundThe cardiovascular risk associated with different levels of hypertensive retinopathy, including mild, remains unclear. We performed an individual participant meta-analysis from 6 population-based cohort studies to determine the relationship of hypertensive retinopathy with incident cardiovascular outcomes. MethodsWe identified cohort studies that objectively assessed hypertensive retinopathy from photographs, documented incident cardiovascular outcomes, and were population-based. Six studies contributed data from 11,013 individuals at baseline with 5–13 years follow-up. Participants were recruited if they had hypertension and did not have confounding conditions such as diabetic retinopathy. Main outcome measures were incident coronary heart disease (CHD), stroke and a composite endpoint of cardiovascular disease (CHD or stroke). Pooled estimates of incident risk ratios (IRR) were obtained after adjusting for age, gender, systolic blood pressure, serum total cholesterol, high density lipoprotein and smoking. ResultsAmong eligible participants with hypertension and without diabetes, there were 1018/9662 (10.5%) incident CHD events, 708/11,013 (6.4%) incident stroke events and 1317/9378 (14.0%) incident CVD events. Mild hypertensive retinopathy was associated with increased risk of CVD (IRR 1.13, 95% CI 1.00 to 1.27) and CHD (IRR 1.17, 95% CI 1.02 to 1.34) but not stroke; moderate hypertensive retinopathy was associated with increased risk of CVD (IRR 1.25 95% CI 1.02 to 1.53) but not stroke or CHD individually. ConclusionsIn persons with hypertension, both mild and moderate hypertensive retinopathy were associated with higher CVD risk.

Novel application of drug-coated balloons in coronary heart disease: A narrative review.

The incidence of coronary heart disease (CAD) has soared over the years, and coronary intervention has become an increasingly important therapeutic approach. The past decade has witnessed unprecedented developments in therapeutic medical instruments. Given that drug-coated balloons bring many benefits, they are indicated for an increasing number of conditions. In this article, we review the results of current clinical trials about drug-coated balloons and summarize their safety and clinical progression in different coronary artery diseases, laying the groundwork for basic research, and clinical therapeutics of this patient population.

Clinical Factors Affecting the Recovery of Sensory Impairment After Cerebral Infarction: A Retrospective Study.

About 75% of patients with cerebral infarction suffer from sensory impairment in varying degrees. It prolongs the time for patients to resume normal life and work. The aim of this study was to retrospectively investigate the clinical characteristics affecting the recovery of sensory impairment. This was a retrospective case-control study. Data of inpatients at the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine were investigated. We collected information on the patients with sensory disturbances after cerebral infarction. Cases were defined according to whether the National Institutes of Health Stroke Scale (NIHSS) and visual analogue scale (VAS) scores improved. A total of 1078 inpatients from January 1, 2019, to December 31, 2021, were screened. Among those, 187 cases included in this study were divided into no improvement and improvement groups. We compared the clinical characteristics affecting the rehabilitation of these patients. The number of patients aged between 63 and 73 years in the no improvement group were significantly higher (P<0.05). The incidence of coronary heart disease and thalamus infarction was significantly higher in patients in the no improvement cohort (P<0.05). Furthermore, coronary heart disease [odds ratio=0.466, 95% confidence interval (0.252, 0.863), P=0.015] and thalamic infarction [odds ratio=0.457, 95% confidence interval (0.230, 0.908), P=0.025] were the independent risk factors against the recovery of sensory disturbance after cerebral infarction. Patients with thalamus infarction and coronary heart disease may be more inclined to recover poorly from somatosensory deficits.

Serum High-Sensitivity Cardiac Troponin T as an Independent Predictor for Incident Coronary Heart Disease in the Japanese General Population: The Circulatory Risk in Communities Study (CIRCS).

Epidemiological evidence is extremely limited about high-sensitivity cardiac troponin T (hs-cTnT) and future coronary heart disease (CHD) events for the general population in countries with low mortality from CHD. Therefore, we investigated the association between hs-cTnT levels and the risk of incident CHD using a nested case-control study in a large Japanese cohort study. The participants were residents of four Japanese communities in the Circulatory Risk in Communities Study (CIRCS). We obtained 120 cases (81 men and 39 women, aged 38-86 years at baseline) of first incident CHD and 240 controls matched by age, sex, communities, and blood sampling term. Serum hs-cTnT levels were measured using an electrochemiluminescence immunoassay with stored sera collected between 2001 and 2011. The median period between sampling at survey and CHD incidence was 2.0 (interquartile range, 0.9-3.7) years. After adjusting for conventional risk factors, the multivariable odds ratios (ORs) of CHD were calculated using conditional logistic regression analyses. hs-cTnT ranged from ≤ 3 (assay detection limit) to 155 ng/L. Compared with the lowest quartile of hs-cTnT, multivariable ORs (95% confidence intervals) of CHD for the second, third, and highest quartiles were 1.30 (0.57-2.95), 2.48 (1.09-5.64), and 3.01 (1.27-7.12), respectively. Similar associations were observed after adjusting for estimated glomerular filtration, or after excluding matched groups, including people with chronic kidney disease. Serum hs-cTnT could predict CHD in the Japanese general population. These findings implicate a benefit from monitoring hs-cTnT to predict CHD even among populations in countries with low mortality from CHD.

Prevalence of Cardiovascular Risk Factors and 10-Years Risk for Coronary Heart Disease in the United Arab Emirates.

In the United Arab Emirates (UAE), cardiovascular diseases (CVDs) are the leading cause of mortality, and the incidence of premature coronary heart diseases (CHDs) is about 10-15 years earlier than that in people of western countries. The current cross-sectional study aims to describe the prevalence of CVD risk factors and estimate the 10-years risk for CHDs in the population of Abu Dhabi, UAE. The main objective was to report the 10-years risk for CHD in a sample of the UAE population. We have analyzed the dataset from the Abu Dhabi Screening Program for Cardiovascular Risk Markers (AD-SALAMA), a population-based cross-sectional survey conducted between 2009 and 2015 (a sample of 1002, 20 to 79 years old without CVDs or diabetes). 18.0% of our sample have had hypertension (HTN), 26.3% were current smokers, 33% have had total cholesterol ≥200 mg/dL, 55.0% have had non-high-density lipoprotein (non-HDL) levels ≥130 mg/dL, 33.1% have had low-density lipoprotein cholesterol (LDL-C) levels ≥130 mg/dL, calculated by β-quantification as 112.3 ± 47.1 mg/dL. 66.8% were overweight or obese, and 46.2% had a sedentary lifestyle. Nearly 85% of our sample has had one or more major cardiovascular risk factors. The estimated 10-year risk of cardiovascular disease according to different risk assessment tools was as follows: 7.1% according to the national cholesterol education program Framingham risk score (FRAM-ATP), 2.9% according to Pooled Cohort Risk Assessment Equation (PCRAE) , 1.4% according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), and 1.1% according to Reynolds Risk Score. Despite the fact that our sample population have had exhibited major risk factors, the above-mentioned international scoring systems underestimate the 10-year risk of cardiovascular diseases, given the high prevalence at younger ages. The proportion of modifiable risk factors has been found to be high in the UAE population, and the majority of them have had one or more risk factors with a higher 10-years risk for CHDs.

Abstract MP23: Circulating Gut Microbiota-Related Metabolites and Risk of Coronary Heart Disease: A Prospective, Multiethnic, Metabolomic Study

Introduction: Despite the importance of gut microbiota in human cardiometabolic health, the associations between circulating levels of gut microbiota-related metabolites and incident coronary heart disease (CHD) remain largely unexplored. Hypothesis: Certain circulating microbial metabolites are associated with incident CHD. Methods: This is a multi-stage and multiethnic metabolomics study. We first conducted a global, semi-quantitative assay for discovery among 900 incident CHD cases and 900 age-/sex-/race-matched controls (300 pairs of Black Americans, White Americans, and Chinese adults, respectively) selected from the Southern Community Cohort Study and Shanghai Men’s and Women’s Health Studies. We focused on 226 metabolites that were potentially related to gut microbiota and applied conditional logistic regression to estimate odds ratios (ORs) of CHD associated with a 1-SD increase of log-transformed metabolites adjusting for traditional CHD risk factors. Then, an in-silico validation was conducted using existing metabolites data of 9,264 participants from the Multi-Ethnic Study of Atherosclerosis and Atherosclerosis Risk in Communities Study. Results: In the discovery stage, we identified 73 named microbial metabolites related to incident CHD risk with a false discovery rate&lt;0.10 or nominal p &lt;0.05 and a large effect size (ORs &gt;1.5 or &lt;0.5). These metabolites were from super pathways of amino acids (n=28), lipids (n=24), nucleotides (n=6), carbohydrates (n=4), energy (n=4), xenobiotics (n=4), and cofactors/vitamins (n=3). Of them, 61 metabolites were available for the in-silico validation, and 30 showed a significant association ( p &lt;0.05) with the same direction as the discovery results. After further adjustments for established CHD risk factors (e.g., glucose and LDL-cholesterol), 25 metabolites remained significant. A 14%-48% increased risk was observed for N-acetylglutamate (OR=1.48), sphingomyelin (1.42), imidazole propionate (1.37), hypoxanthine (1.29), guaiacol sulfate (1.28), glutamate (1.22), 2-hydroxyphenylacetate (1.20), 3-hydroxybutyrate (1.19), 3-hydroxy-2-ethylpropionate (1.17), 1-methyl-4-imidazoleacetate (1.16), urea (1.16), urate (1.16), 4-hydroxyphenylacetate (1.15), choline (1.15), isoleucine (1.14), and glycerol (1.14). Meanwhile, a significant inverse association was found for taurine (OR=0.64), asparagine (0.75), serotonin (0.78), histidine (0.79), threonine (0.81), glutamine (0.83), glycine (0.84), oxalate (0.85), and N-methylproline (0.89). Conclusions: Among ethnically and geographically diverse populations, we identified and validated some circulating gut microbiota-related metabolites as potential novel biomarkers for incident CHD.

Abstract P449: Life’s Essential 8 and Risk of Coronary Heart Disease: A Prospective Study Among Racially and Geographically Diverse Populations

Introduction: Life’s Essential 8 (LE8) is a new guideline proposed by American Heart Association to improve cardiovascular health, including four health behaviors (i.e., eat better, be more active, quit tobacco, get healthy sleep) and four health factors (i.e., manage weight, control cholesterol, manage blood sugar, manage blood pressure). Hypothesis: Higher adherence to LE8 is associated with reduced risk of coronary heart disease (CHD) among racially and geographically diverse populations. Methods: The current analysis was based on CHD case-control studies nested within the Southern Community Cohort Study (baseline: 2002-2009), Shanghai Women’s Health Study (1996-2000), and Shanghai Men’s Health Study (2002-2006), including 900 incident CHD cases identified through 2018 and 900 age-/sex-/race-matched controls (300 pairs of White Americans, Black Americans, and Chinese adults, respectively). Within each cohort, we constructed the LE8 score (range: 0 to 100) based on DASH diet quality, moderate/vigorous physical activity, tobacco smoking, sleep hours, body mass index, total and non-HDL cholesterol, diabetes status/blood glucose, and hypertension status/blood pressure. We used conditional logistic regression to evaluate odds ratios (ORs) between the LE8 score and incident CHD, adjusting for sociodemographic factors and family history of CHD. Results: The mean ± standard deviation (SD) of LE8 score was 48.1±13.4 among White women, 48.5±14.4 among White men, 48.1±12.3 among Black women, 50.0±13.6 among Black men, 57.2±12.2 among Chinese women, and 50.7±12.5 among Chinese men. Higher LE8 score was associated with significantly reduced risk of CHD: OR for 1-SD increase was 0.58 (95% CI: 0.51-0.65) among all participants, 0.64 (95% CI: 0.53-0.78) among White Americans, 0.57 (95% CI: 0.46-0.69) among Black Americans, 0.52 (95% CI: 0.42-0.65) among Chinese, 0.49 (95% CI: 0.41-0.60) among women, and 0.65 (95% CI: 0.56-0.75) among men; all P &lt;0.001 ( P interaction &gt;0.05 for race and P interaction =0.01 for sex). Similar patterns of beneficial associations were also found in stratified analyses by age group, education level, and history of diabetes, hypertension, or dyslipidemia, with ORs ranging from 0.46 to 0.74. Conclusions: Higher adherence to LE8 is associated with ~35-50% reduced risk of incident CHD across racially and geographically diverse populations, supporting the importance of promoting healthy lifestyles and maintaining metabolic health.
