Associations of Neighborhood Food and Physical Activity Environments in Young Adulthood With Cardiovascular Health in Midlife: The CARDIA Study.

Adults who maintain ideal cardiovascular health (CVH) profiles up to midlife have lower risk of several chronic diseases and better quality of life. Some evidence suggests that individual-level exposures earlier in life shape midlife CVH, but the impact of neighborhood-level exposures over the life course remains understudied. Participants were 3017 Black and White men and women aged 18 to 30 years at baseline (1985-1986), recruited from Birmingham, Alabama; Minneapolis, Minnesota; Chicago, Illinois; and Oakland, California, as part of the CARDIA (Coronary Artery Risk Development in Young Adults) study. Measures of the neighborhood food and physical activity environment were linked to participant addresses collected at baseline. CVH was measured on the basis of the American Heart Association's Life's Simple 7 criteria in young adulthood and 30 years later (2015-2016) when participants were midlife (aged 48-60 years). Associations of young adult neighborhood food environment and physical activity resources with midlife CVH (moderate versus high and low versus high) were examined using multinomial logistic regression. Models were adjusted for young adult sociodemographic factors. Participants who lived farther away from a major park in young adulthood were more likely to have low versus high CVH scores (odds ratio, 1.54 [95% CI, 1.22-1.96]) and more likely to have moderate versus high CVH scores (odds ratio, 1.39 [95% CI, 1.12-1.73]) in midlife. No other neighborhood measures were significantly associated with CVH. Young adulthood may be a sensitive period in which having convenient access to physical activity-promoting resources may help them establish healthy habits that can carry into midlife.

Association between life's essential 8 and cognitive impairment in older patients: results from NHANES 2011-2014.

This study aimed to examine the association between the American Heart Association's (AHA) newly revised Life's Essential 8 (LE8) algorithm, designed for assessing cardiovascular health (CVH), and cognitive impairment among older adults in the United States. This study employed a cross-sectional design, utilizing data from the 2011-2014 National Health and Nutrition Examination Survey to explore the relationship between CVH and cognitive impairment in older adults. CVH scores are assessed based on the AHA definition of the LE8, categorized into three tiers: low (0-49), medium (50-79), and high (80-100). Cognitive impairment is evaluated using three distinct scoring systems: the Consortium to Establish a Registry for Alzheimer's Disease (CERAD), the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST). The lowest quartile as the cut-off point; below or equal to the lower quartile was considered as low cognitive population, and above the lower quartile was normal population. To analyze the association, multivariable logistic regression and restricted cubic spline (RCS) models were employed. A significant negative correlation exists between the LE8 and cognitive impairment. After adjusting for multiple variables, the odds ratios (OR) for cognitive impairment, as measured by the CERAD, AFT, and DSST, were compared between patients with high and low CVH. The results indicated OR values of 0.60 (95% CI: 0.36-0.98), 0.72 (95% CI: 0.52-0.97), and 0.29 (95% CI: 0.16-0.53) for the CERAD, AFT, and DSST, respectively. Additionally, the RCS curve demonstrated a significant linear relationship between lifestyle factors encapsulated by the LE8 and cognitive impairment. The findings indicate higher adherence to LE8 was associated with lower odds of cognitive impairment. Furthermore, maintaining optimal CVH is crucial in preventing cognitive impairment.

Abstract 4132288: Associations Between Health-Related Social Needs and Cardiovascular Health Among US Adults

Background Unfavorable: health-related social needs (HRSNs) have the potential to worsen health and wellbeing and drive health disparities. Its associations with cardiovascular health (CVH), assessed by Life’s Essential 8 (LE8), have not been comprehensively examined among US adults. Research Questions/Hypothesis: Whether unfavorable HRSNs are associated with worse CVH. Goals/Aims: To determine associations between unfavorable HRSNs and CVH in a large, diverse, nationally representative sample of US adults. Methods: We used the National Health and Nutrition Examination Survey 2011–March 2020 data for adults aged ≥20 years. We grouped LE8 scores as low (0–49), moderate (50–79), and high (80–100) CVH. We identified 8 unfavorable HRSNs: unemployed, low family poverty-to-income ratio, food insecurity, less than high school education, no healthcare access, no health insurance, no homeownership, and living alone. We assigned a value of 1 for the unfavorable status of each. The number of unfavorable HRSNs was summed and ranged from 0 to 8, with higher numbers indicating more unfavorable HRSNs. We categorized unfavorable HRSNs as none, 1–2, 3–4, and ≥5. We used multivariable linear and multinomial logistic regression to examine the association between HRSNs and CVH. Results: We included 14 947 participants (n=7340 male [49.3%]; mean [SE] age, 46.4 [0.35] years). Of those, 29.1% were categorized as having HRSNs 0, 40.4%; HRSNs 1–2, 21.5% HRSNs 3–4, and 9.0% HRSNs ≥5. The prevalence of low, moderate, and high CVH was 14.7%, 63.5%, and 21.8%, respectively. Every one-unit increase in unfavorable HRSNs was associated with 1.59 points lower LE8 scores ( P <.001). Comparing participants with HRSNs values of 1–2, 3–4, and ≥5 to those with none, the fully adjusted prevalence ratios for low CVH were 1.42 (1.17–1.73), 2.11 (1.69–2.63), and 2.42 (1.90–3.08), respectively. The corresponding prevalence ratios for high CVH were 0.77 (0.68–0.87), 0.58 (0.49–0.67), and 0.46 (0.38–0.55). The associations were consistent across subgroups and in sensitivity analyses. Conclusions: A graded association exists between unfavorable HRSNs and higher prevalence of low CVH or lower prevalence of high CVH. Public health interventions targeting unfavorable HRSNs might reduce health disparities and promote CVH.

Abstract 4121568: The Influence of Cardiovascular Health on Atherosclerotic Cardiovascular Disease Progression and Life Expectancy Among Individuals with Type 2 Diabetes

Objective: This study aims to evaluate whether cardiovascular health (CVH) plays a similar role in the transition from a healthy state to atherosclerotic cardiovascular disease (ASCVD) and subsequent mortality rates in diabetic patients compared to those without diabetes. It also evaluates the effectiveness of CVH in reducing diabetes-related ASCVD risks and enhancing ASCVD-free life expectancy. Research design and methods: This cohort study included 176,669 adults from the UK Biobank, among whom 10,109 (22.3%) were diagnosed with type 2 diabetes mellitus (T2DM). CVH was assessed using the Life's Essential 8 score, encompassing diet, physical activity, smoking, sleep, BMI, blood lipids, blood glucose, and blood pressure. CVH scores were categorized into low, moderate, and high levels based on their distribution among diabetic patients. The main outcomes were the transitions from no ASCVD to the onset of ASCVD and then to mortality, as well as the ASCVD-free life expectancy. Results: In patients with T2DM, high CVH levels were associated with lower ASCVD risk (HR: 0.55, 95% CI: 0.45-0.68 for women; HR: 0.57, 95% CI: 0.50-0.65 for men) and reduced mortality in those with ASCVD (HR: 0.62, 95% CI: 0.39-0.98 for women; HR: 0.62, 95% CI: 0.48-0.79 for men), compared to the low CVH group. No significant difference in CVH's effect on ASCVD and mortality was observed between diabetic and non-diabetic groups. When compared with non-diabetic individuals, no excess risk was observed in incident ASCVD and post-ASCVD mortality among diabetic patients with high CVH. At the age of 40, women with low CVH were expected to live 38.5 years (38.0-39.1) free from ASCVD, which increased to 42.9 years (42.4-43.5) for those with high CVH, while non-diabetic women were predicted to have an ASCVD-free life expectancy of 44.1 years (43.5-44.6). For men at the age of 40, those with low CVH had an ASCVD-free life expectancy of 32.0 years (31.3-32.6), which rose to 37.9 years (37.4-38.6) with high CVH. Non-diabetic men were expected to live 38.3 years (37.7-39.0) free from ASCVD. Notably, life expectancy with ASCVD did not increase with higher CVH levels in both genders. Conclusions: Our findings suggest that the American Heart Association’s recommendations for promoting CVH, initially designed for the general population, are also beneficial for individuals with T2DM. Adopting these guidelines can help mitigate ASCVD progression and enhance life expectancy in diabetic patients.

Abstract 4134272: Association of depression symptoms with cardiovascular health stratified by military status: Insights from 2013-2020 National Health and Nutrition Examination Survey

Introduction: Emerging evidence supports the mind-heart-body connection, yet less attention has been given to examining the relationship in specific populations. Veterans have a higher risk for mental and cardiovascular problems and have unique social determinants of health (SDoH), such as healthcare access, than civilians. This study aims to examine how depression and SDoH are associated with cardiovascular health (CVH) and if associations differ by military status. Hypotheses: 1) Depression symptoms and SDoH will be associated with CVH. 2) The associations will differ between people who served in the US military and those who did not. Methods: A cross-sectional analysis was conducted using data from the 2013 to 2020 National Health and Nutrition Examination Survey. Individuals were aged ≥ 20 years without cardiovascular disease and current pregnancy. Patient Health Questionnaire-9 was used to assess depression symptoms and dichotomized into no symptoms (<5) and mild-to-severe symptoms (≥5). The Life's Essential 8 quantified CVH, with scores from 0-100. SDoH included age, gender, race/ethnicity, marital status, education, employment, financial status, health insurance, and healthcare access. Sample weights were applied in multiple linear regression analyses. Results: Among 6498 participants, 92% were civilians (mean age: 45 years; 51% female), and 8% were veterans (mean age: 56 years; 10% female). In both groups, 23% had depression symptoms. The mean CVH was 72 in civilians and 69 in veterans. In adjusted models, individuals with depression symptoms had 4 points lower CVH scores than those without (95% CI: -5.11, -2.84). This trend was similar in civilians but insignificant in veterans. Lower CVH was significantly associated with age, being non-Hispanic Black and other races people, lower education, and lower financial status. The associations were preserved after being stratified by military status. Conclusions: Depression symptoms and SDoH were associated with lower CVH. However, there was no significant evidence that military status moderated the associations of depression and SDoH with CVH. Examining the intersection between depressive symptoms and SDoH may be useful when assessing CVH.

Interactive association of metals and Life’s Essential 8 with mortality in U.S. adults: a prospective cohort study from the NHANES dataset

BackgroundLife’s Essential 8 (LE8) is a novel assessment of cardiovascular health (CVH) by evaluating lifestyle, and reports of the associations between LE8 and urinary metals on mortality have been very limited. This study aimed to conduct a prospective cohort study and investigate the combined effects of metals and LE8 on mortality in U.S. adults.MethodsThis study enrolled participants with complete information on urinary metals, LE8, mortality status, and confounders from the National Health and Nutrition Examination Survey (2005–2018). The Cox regression model, adaptive lasso penalized regression, and restricted cubic spline were used to analyze the individual effects of metals and LE8 on all-cause mortality. The additive and multiplicative interaction scales and quantile g-computation were used to evaluate the interaction and combined effects. Stratified analyses were performed to clarify whether metals and LE8 interacted with other variables to influence all-cause mortality.ResultsA total of 8017 participants were included in this study. The concentrations of cadmium, cobalt, lead, antimony, and thorium were greater in the low CVH group than in the high CVH group [median (µg/L): 0.29 vs. 0.19, 0.36 vs. 0.35, 0.48 vs. 0.39, 0.05 vs. 0.04, and 0.07 vs. 0.06]. The interaction between cadmium and LE8 was statistically significant, with a synergy index of 1.169 (95% CI: 1.004, 1.361). The stratified analyses showed that the interaction between age and LE8 had an impact on all-cause mortality (P for interaction = 0.004).ConclusionsIn this representative sample of the U.S. population, we found that the combined effect of cadmium, lead, thallium, and LE8 was positively associated with all-cause mortality. Furthermore, the interaction between cadmium and LE8 influenced all-cause mortality. So people should adopt healthy behaviors and reduce heavy metal exposure to minimize the risk of adverse health outcomes.

Association of the Life's Essential 8 cardiovascular health score with periodontitis among US adults.

To investigate whether cardiovascular health (CVH) is associated with periodontitis. We used data from the 2009 to 2014 National Health and Nutrition Examination Survey. We quantified CVH using Life's Essential 8, which includes four health behaviours (diet, smoking, physical activity and sleep) and four health factors (body mass index, blood cholesterol, glucose and pressure). We categorized scores as low (0-49), moderate (50-79) and high (80-100). We calculated subscores of health behaviours and factors and categorized them as low, moderate and high. We used logistic regression to assess the association of CVH with periodontitis, adjusting for age, gender, race/ethnicity, education, poverty index, marital status and health insurance. We computed odds ratios (ORs) and 95% confidence intervals (CIs). This study included 9296 adults ≥30 years old. Multivariable-adjusted models showed that subjects with moderate (OR, 0.62; 95% CI: 0.52-0.74) or high (OR, 0.43; 95% CI: 0.33-0.57) CVH had significantly lower odds of periodontitis compared to those with low CVH. These results were consistent in the health behaviours model, but the estimates in the health factors model were not significant. Improving CVH may help prevent periodontitis. Longitudinal studies are needed to confirm our findings.

The inverse relationship between Life's Essential 8 and risk of metabolic syndrome: evidence from NHANES 2005-2018.

Metabolic syndrome (MetS) has a close association with cardiovascular diseases. Few studies have investigated the association of Life's Essential 8 (LE8), the updated measurement of cardiovascular health (CVH), with MetS. The National Health and Nutrition Examination Survey (2005-2018) data was extracted. The LE8 comprised 4 health behaviors (diet, physical activity, nicotine exposure, and sleep health) and 4 health factors [body mass index (BMI), blood lipids, blood glucose, and blood pressure (BP)]. The total LE8 score is the average of 8 metric scores (0-100), categorized into low (0-49), moderate (50-79), and high CVH (80-100) levels. Multivariable logistic regression models, restricted cubic spline models and stratified analyses were performed to examine the relationship between LE8 and MetS. In this study, a total of 21,543 participants represented 146.6 million non-institutionalized U.S. adults. Following adjustment for various potential covariates, participants who attained a moderate [adjusted odds ratio (AOR) = 0.234, 95% CI: 0.209, 0.262] or a high CVH level (AOR = 0.026, 95% CI: 0.021, 0.032) exhibited an inverse correlation with MetS risks when comparing those with a low CVH level. An inverse linear dose-response relationship between LE8 scores and MetS risks was also identified (P for nonlinearity > 0.05). LE8 was inversely associated with the risk of MetS. Adhering to LE8 guidelines to sustain a higher CVH level may be beneficial for preventing MetS.

Lowering the risk of hyperuricemia and gout is associated with ideal cardiovascular health

BackgroundHyperuricemia (HUA) and gout have been demonstrated as independent risk factors for cardiovascular disease. The relationship between the recently updated Life’s Essentials 8 (LE8), which measures ideal cardiovascular health (CVH), and HUA and gout remains unclear. The aim of this study was to explore the relationship between CVH and the prevalence of HUA and gout among a nationally representative sample of US adults.MethodsThis study utilized cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) for the years 2007 to 2018. The CVH scores and their corresponding components were defined according to the guidelines established by the American Heart Association. The association between the LE8 score and both HUA and gout was assessed using weighted multivariable logistic and restricted cubic spline (RCS) models.ResultsAmong the 21,155 participants aged 20 years and older, the prevalence of HUA was 17.20% (95% CI, 16.05–18.36%), and the prevalence of gout was 3.58% (95% CI, 3.13–4.02%). After adjusting for potential confounders, compared to participants exhibiting low CVH, the multivariable adjusted odds ratio (OR) for HUA was 0.65 (95% CI, 0.56–0.75) in those with moderate CVH, and 0.25 (95% CI, 0.20–0.31) in those with high CVH. Additionally, compared to participants with low CVH, the multivariable adjusted OR for gout was 0.66 (95% CI, 0.53–0.81) in those with moderate CVH and 0.32 (95% CI, 0.20–0.50) in those with high CVH. The LE8 score exhibited a significant nonlinear negative association with HUA and linear negative correlation with gout. In subgroup analyses focusing on HUA, significant interactions were observed between LE8 score and age, sex, and CKD (P for interaction < 0.05). For gout, only a significant interaction between LE8 score and sex was observed (P for interaction < 0.05).ConclusionsAmong adults, there was a significant negative correlation between LE8 score and the prevalence of HUA and gout. Maintaining an ideal CVH may be beneficial in reducing the burden of HUA and gout.

The correlation between Life’s essential 8 and cardiovascular disease and mortality in individuals with nonalcoholic fatty liver disease: a cross-sectional study

It is currently unclear whether there is a connection between Life’s Essential 8 (LE8) and cardiovascular disease (CVD), as well as mortality in people with nonalcoholic fatty liver disease (NAFLD). Our goal was to explore these relationships by examining data collected in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. We identified eligible participants with NAFLD based on NHANES 2005–2018 data. CVD status was acquired through self-reported information, and using the National Death Index, mortality data were prospectively matched. The diagnosis of NAFLD relied on noninvasive biomarkers. The research involved 9094 individuals who were identified as having NAFLD, with a mean age of 52.05 years. Each incremental LE8 score exhibited a significant association, leading to a 3%, 3%, 4%, 3%, 3%, 4%, and 4% reduction in the odds of experiencing CVD, ischemic heart disease, congestive heart failure, coronary heart disease, heart attack, angina, and stroke in individuals with NAFLD. A strong correlation was found between maintaining a superior level of Cardiovascular Health (CVH), as shown by a LE8 score ranging from 80 to 100, and a reduced occurrence of CVD and its various forms in NAFLD (all p for trend < 0.0001). Likewise, LE8 demonstrated protective benefits on mortality in NAFLD, showing that following a high CVH (in contrast to low CVH) was linked to reductions of 64%, 71%, and 74% in all-cause, CVD, and cancer mortality, respectively. Restricted cubic spline analyses suggested noteworthy dose-response relationships between LE8 and CVD, specifically its types in NAFLD, and a nonlinear correlation with CVD mortality. Interaction analyses highlighted age and race as significant effect modifiers. CVH, as evaluated by LE8, demonstrated an independent association with decreased odds of CVD and mortality risk in individuals with NAFLD. Our findings substantiate that adhering to LE8 may alleviate the excessive burden of CVD and mortality in the context of NAFLD.

The association of ideal cardiovascular health and its change with subclinical atherosclerosis according to glucose status: A prospective cohort study.

An updated definition was developed to better evaluate cardiovascular health (CVH). We aimed to investigate whether optimal or improvement of six CVH metrics defined by new Life's Essential 8 (LE8) may counteract the risk of subclinical atherosclerosis among patients with hyperglycemia. We conducted a prospective analysis of 5225 participants without prior cardiovascular diseases, of whom 4768 had complete data on CVH change. Subjects with CVH scores of 0-49, 50-79, and 80-100 points were categorized as having low, moderate, or high CVH, respectively. Subclinical atherosclerosis was evaluated by brachial-ankle pulse wave velocity, pulse pressure and albuminuria, both separately and in combination. Of the 5225 participants, 1937 (37.1%) had normal glucose regulation, while 3288 (62.9%) had hyperglycemia. The multivariable-adjusted odds ratio (OR) for composite subclinical atherosclerosis was 2.34 (95% confidence interval [CI], 1.88-2.91), 1.43 (95% CI, 1.21-1.70), and 0.74 (95% CI, 0.46-1.18), for participants with hyperglycemia who had low, moderate, or high overall CVH scores, respectively, compared with participants with normal glucose regulation. In addition, compared with those with stable CVH and normal glucose regulation, participants who exhibited greater improvements in overall CVH from 2010 to 2014 had a reduced risk of composite subclinical atherosclerosis with an OR of 0.72 (95% CI, 0.53-0.98) for those with normal glucose regulation, and 1.13 (95% CI, 0.87-1.48) for those with hyperglycemia. The novel defined CVH using six metrics was inversely associated with subsequent risk of subclinical atherosclerosis. Both the status of CVH and its changes modified the relationship between hyperglycemia and subclinical atherosclerosis.

Association of life's essential 8 with mortalities in patients with alcohol-related liver disease.

Alcohol-related liver disease (ALD) and cardiovascular diseases share some common risk factors. This study aims to investigate the associations between Life's Essential 8 (LE8), a comprehensive measure of cardiovascular health (CVH), and outcomes of ALD. Data were obtained from the 2011-2018 National Health and Nutrition Examination Survey (NHANES). Cox proportional hazards models were employed to assess the relationships between LE8 and all-cause and cardiovascular mortality in patients with ALD. Additionally, restricted cubic splines (RCS), piecewise regression, and subgroup analyses were conducted. A total of 5321 ALD patients were included in this study with a mean LE8 score of 67.38. During a median follow-up period of 63 months, 228 all-cause deaths were recorded. After adjusting for potential confounders, the risk of all-cause mortality in the high CVH group decreased by 53.7% compared to the low CVH group (HR = 0.463, 95%CI = 0.223-0.965). The result was robust in subgroup analyses. The RCS analysis indicated a non-linear relationship between LE8 and cardiovascular mortality, showing that the risk of cardiovascular mortality decreased with increasing LE8 scores for values below 71.12 (HR = 0.949, 95% CI = 0.915-0.984). LE8 score is inversely and linearly linked to all-cause mortality in ALD patients. Promoting adherence to optimal cardiovascular health may unveil additional strategies for the effective management of ALD patients and contribute to reducing their long-term mortality.

Cardiovascular health, measured using Life's Essential 8, is associated with reduced dementia risk among older men and women.

Dementia poses considerable challenges to healthy aging. Prevention and management of dementia are essential given the lack of effective treatments for this condition. A secondary data analysis was conducted using data from 928 InCHIANTI study participants (55% female) aged 65 years and older without dementia at baseline. Cardiovascular health (CVH) was assessed by the "Life's Essential 8" (LE8) metric that included health behaviors (diet, physical activity, smoking status, sleep duration) and health factors (body mass index, blood lipid, blood glucose, blood pressure). This new LE8 metric scores from 0 to 100, with categorization including "low LE8" (0-49), indicating low CVH, "moderate LE8 (50-79)", indicating moderate CVH, and "high LE8 (80-100)", indicating high CVH. Dementia was ascertained by a combination of neuropsychological testing and clinical assessment at each follow-up visit. Cox proportional hazards models were used to examine associations between CVH at baseline and risk of incident dementia after a median follow-up of 14 years. Better CVH (moderate/high LE8 vs. low LE8) was inversely associated with the risk of incident dementia (hazard ratio [HR]: 0.61, 95% confidence interval [CI]: 0.46-0.83, p = 0.001). Compared with health factors, higher scores of the health behaviors (per 1 standard deviation [SD]), specifically weekly moderate-to-vigorous physical activity time (per 1 SD), were significantly associated with a lower risk of incident dementia (health behaviors: HR:0.84, CI:0.73-0.96, p = 0.01; physical activity: HR: 0.62, CI: 0.53-0.72, p < 0.001). While longitudinal studies with repeated measures of CVH are needed to confirm these findings, improving CVH, measured by the LE8 metric, may be a promising dementia prevention strategy.

Life's Essential 8, genetic susceptibility, and risk of incident pancreatic cancer: A prospective cohort study.

The association between the American Heart Association (AHA) Life's Essential 8 (LE8) and the risk of pancreatic cancer (PC) remains unclear. Our goal was to assess the relationships between LE8, genetic susceptibility, and PC risk. This cohort consisted of 234,102 participants from the UK Biobank. The components of LE8 include diet, nicotine exposure, sleep, physical activity, blood glucose, body mass index, blood lipids, and blood pressure. LE8 is classified into three categories: low cardiovascular health (CVH), moderate CVH, and high CVH. Measurements were made using Cox proportional risk models to estimate impact of associations between LE8, genetic susceptibility, and incidence of PC in participants. Compared to participants with low LE8 scores, those with moderate and high LE8 scores had a 53% (HR, 0.47; 95% CI, 0.39-0.57) and 70% (HR, 0.30; 95% CI, 0.22-0.41) lower risk of developing PC, respectively. Interestingly, among individuals with high genetic risk, high LE8 scores were associated with greater benefits (HR, 0.24; 95% CI, 0.15-0.40), whereas the protective effect was weaker among those with low genetic risk (HR, 0.40; 95% CI, 0.21-0.75). Participants with a high LE8 score and a low polygenic risk score (PRS) had the lowest risk of PC (HR, 0.19; 95% CI: 0.11-0.33). Furthermore, we observed a significant additive interaction between LE8 and PRS. A higher LE8 score is associated with a lower risk of PC, especially for participants with a high PRS. These findings have important implications for participants most genetically predisposed to PC and for targeted strategies for PC prevention.

Association of life’s essential 8 with chronic cardiovascular-kidney disorder: a prospective cohort study

BackgroundThe coexistence of cardiovascular disease and chronic kidney disease, termed chronic cardiovascular-kidney disorder (CCV-KD), is increasingly prevalent. However, limited studies have assessed the association between cardiovascular health (CVH), assessed by the American Heart Association’s Life’s Essential 8 (LE8), and CCV-KD.MethodsWe conducted a prospective cohort study using data from UK Biobank. Participants without cardiovascular disease and chronic kidney disease at baseline and having complete data on metrics of LE8 were included (N = 125,986). LE8 included eight metrics, and the aggregate score was categorized as low (< 50 points), intermediate (50 to < 80 points), and high (≥ 80 points), with a higher score indicating better CVH health. Adjusted Cox proportional hazard models were conducted to explore the association of CVH with the risk of CCV-KD. The adjusted proportion of population attributable risk (PAR%) was used to calculate the population-level risk caused by low or intermediate CVH.ResultsDuring a median follow-up of 12.5 years, 1,054 participants (0.8%) had incident CCV-KD. Participants with intermediate and high CVH had 54% (HR = 0.46, 95% CI: 0.40–0.54, P < 0.001) and 75% (HR = 0.25, 95% CI: 0.18–0.34, P < 0.001) lower risks of incident CCV-KD compared with those in low CVH group. There was an approximately dose–response linear relationship between the overall LE8 score and incident CCV-KD. The risk of incident CCV-KD decreased by 30% (HR = 0.70, 95% CI: 0.67–0.74, P < 0.001) for a 10-point increment of LE8 score. The adjusted PAR% of lower overall CVH was 47.4% (95% CI: 31.6%-59.8%).ConclusionsBetter CVH, assessed by using LE8 score, was strongly associated with decreased risk of incident CCV-KD. These findings imply optimizing CVH may be a preventive strategy to reduce the burden of CCV-KD.

Cardiovascular health and cancer mortality: evidence from US NHANES and UK Biobank cohort studies

BackgroundThe American Heart Association recently introduced a novel cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the relationship between LE8 and cancer mortality risk remains uncertain.MethodsWe investigated 17,076 participants from US National Health and Nutrition Examination Survey (US NHANES) and 272,727 participants from UK Biobank, all free of cancer at baseline. The CVH score, based on LE8 metrics, incorporates four health behaviors (diet, physical activity, smoking, and sleep) and four health factors (body mass index, lipid, blood glucose, and blood pressure). Self-reported questionnaires assessed health behaviors. Primary outcomes were mortality rates for total cancer and its subtypes. The association between CVH score (continuous and categorical variable) and outcomes was examined using Cox model with adjustments. Cancer subtypes-related polygenic risk score (PRS) was constructed to evaluate its interactions with CVH on cancer death risk.ResultsOver 141,526 person-years in US NHANES, 424 cancer-related deaths occurred, and in UK Biobank, 8,872 cancer deaths were documented during 3,690,893 person-years. High CVH was associated with reduced overall cancer mortality compared to low CVH (HR 0.58, 95% CI 0.37–0.91 in US NHANES; 0.51, 0.46–0.57 in UK Biobank). Each one-standard deviation increase in CVH score was linked to a 19% decrease in cancer mortality (HR: 0.81; 95% CI: 0.73–0.91) in US NHANES and a 19% decrease (HR: 0.81; 95% CI: 0.79–0.83) in UK Biobank. Adhering to ideal CVH was linearly associated with decreased risks of death from lung, bladder, liver, kidney, esophageal, breast, colorectal, pancreatic, and gastric cancers in UK Biobank. Furthermore, integrating genetic data revealed individuals with low PRS and high CVH exhibited the lowest mortality from eight cancers (HRs ranged from 0.36 to 0.57) compared to those with high PRS and low CVH. No significant modification of the association between CVH and mortality risk for eight cancers by genetic predisposition was observed. Subgroup analyses showed a more pronounced protective association for overall cancer mortality among younger participants and those with lower socio-economic status.ConclusionsMaintaining optimal CVH is associated with a substantial reduction in the risk of overall cancer mortality. Adherence to ideal CVH correlates linearly with decreased mortality risk across multiple cancer subtypes. Individuals with both ideal CVH and high genetic predisposition demonstrated significant health benefits. These findings support adopting ideal CVH as an intervention strategy to mitigate cancer mortality risk and promote healthy aging.

Association of life’s essential 8 and asthma: mediating effect of inflammation and oxidative stress

Background The association of cardiovascular health (CVH) with asthma risk in U.S. adults remains unclear. This study aimed to explore the association of Life’s Essential 8 (LE8), a measurement of CVH, with asthma and investigate the potential mediating effect of inflammation and oxidative stress. Methods The data was obtained from the National Health and Nutrition Examination Survey (NHANES) in 2005–2018. LE8 score (range 0 ∼ 100) was measured and categorized as low (<50), moderate (50 ∼ <80), and high (≥80) CVH. Survey-weighted logistic regression and restricted cubic spline model were employed to explore the association between LE8 score and asthma. Mediation analyses were conducted to identify the mediating effects of inflammation and oxidative stress biomarkers. Results This study included 10,932 participants aged ≥ 20 years, among whom 890 (8.14%) reported prevalent asthma. After adjusting for all covariates, the odd ratios (OR) for asthma were 0.67 (95% confidence interval (CI): 0.48, 0.94) in the moderate CVH group and 0.52 (95% CI: 0.34, 0.79) in the high CVH group compared with the low CVH group, respectively. The OR for asthma was 0.85 (95% CI: 0.78, 0.93) for every 10 score increase in LE8 score, and linear dose-response relationship was observed (p = 0.0642). Mediation analyses showed that inflammation and oxidative stress mediated 15.97% and 11.50% of the association between LE8 score and asthma, respectively (all p < 0.05). Conclusions LE8 score was negatively associated with asthma, and inflammation and oxidative stress partially mediated this association. It is recommended that maintaining optimal CVH may prevent asthma.

Abstract 48: Cardiovascular Health Modifies Genetic Risk for the Hypertensive Disorders of Pregnancy

Introduction: Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal/perinatal mortality. In recent work, a genetic risk score improved prediction of HDPs beyond standard clinical risk factors, but the extent to which cardiovascular health (CVH) modifies HDP genetic risk is unknown. Hypothesis: First-trimester CVH can offset genetic risk for HDPs. Methods: We examined genotyped participants of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (nuMoM2b). Individual HDP genetic risk was calculated using a validated polygenic score. A composite first-trimester CVH score was adapted from the Life’s Essential 8 model; cholesterol was incorporated in a subset (47%) with available first-trimester values. Genetic risk and CVH were each grouped as low (bottom quintile), intermediate (Q2-4), and high (top quintile). Logistic regression tested the joint association of CVH and genetic risk with HDP, adjusted for age and sociodemographic covariates. Results: Among 5,446 participants (mean age 27.5 years), 1,339 (24.6%) developed HDP (344 [6.3%] preeclampsia, 995 [18.3%] gestational hypertension [GH]). Higher genetic risk and lower CVH were additively associated with risk of HDP ( Figure 1A-B ) with no significant interaction (P[interaction] &gt;0.05). HDP incidence ranged from 11% (low genetic risk, favorable CVH) to 37% (high genetic risk, unfavorable CVH) ( Figure 1C ). Favorable vs. unfavorable CVH was associated with 35-62% lower risk of HDPs across genetic risk groups. Findings were broadly consistent when examining preeclampsia and GH separately and when incorporating cholesterol (i.e., using a complete Life’s Essential 8 score). Among CVH components, nonideal BMI, blood pressure, and diet conferred highest population attributable HDP risk (25%, 14%, and 12%, respectively). Conclusion: Higher genetic risk and lower first trimester CVH were additively associated with risk of developing HDP. Favorable CVH in early pregnancy may partially offset a higher genetic risk for HDP.

Life’s Essential 8 and Mortality in US Adults With Obesity: A Cohort Study

ObjectiveThis study evaluates the relationship between the Life’s Essential 8 (LE8) scoring system and all-cause and cause-specific mortality among obese individuals using National Health and Nutrition Examination Survey data. MethodsData from 9143 obese participants (BMI ≥30 kg/m2) collected between 2005 and 2018 were analyzed. Participants were categorized based on their LE8 scores: low cardiovascular health (Low CVH, n = 2264), moderate cardiovascular health (Moderate CVH, n = 6541), and high cardiovascular health (High CVH, n = 338). Associations between LE8 scores and mortality were assessed using Kaplan-Meier survival analysis and Cox proportional hazards models. ResultsOver a median follow-up of 7.3 years, there were 867 all-cause deaths (9.5%), including 246 cardiovascular disease (CVD) deaths (2.7%) and 621 non-CVD deaths (6.8%). In multivariable Cox regression analysis, compared to the Low CVH group, the Moderate CVH group had an adjusted hazard ratio (HR) for all-cause mortality of 0.63 (95% CI: 0.55-0.72), and the High CVH group had an HR of 0.25 (95% CI: 0.10-0.60). For CVD mortality, the HRs were 0.61 (95% CI: 0.47-0.78) for Moderate CVH and 0.19 (95% CI: 0.03-1.38) for High CVH. For non-CVD mortality, the HRs were 0.64 (95% CI: 0.54-0.75) for Moderate CVH and 0.27 (95% CI: 0.10-0.72) for High CVH. Each 10-point increase in LE8 score was associated with a 20% reduction in all-cause mortality (P < .001), 21% reduction in CVD mortality (P < .001), and 20% reduction in non-CVD mortality (P < .001). ConclusionHigher LE8 scores are significantly associated with lower rates of all-cause, CVD, and non-CVD mortality among obese individuals. These findings support the LE8 scoring system as an effective predictor of health status and mortality risk.

Association between cardiovascular health and all-cause mortality risk in patients with osteoarthritis

BackgroundThis study was to explore the relationship between cardiovascular health (CVH) and the risk of all-cause mortality in patients with osteoarthritis (OA).MethodsThis cohort study retrieved the data of 3642 patients with OA aged ≥ 20 years from the 2007—2018 National Health and Nutrition Examination Survey (NHANES). CVH was evaluated based on Life’s Essential 8 (LE8) includes diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids, blood glucose, and blood pressure. The outcome of all-cause mortality was assessed using the death certificate records of participants from the National Death Index. Variables that might affect all-cause mortality were used as covariates. The weighted univariate COX proportional hazards model was used to explore the association between each covariate and all-cause mortality. The weighted univariate and multivariate COX proportional hazards models were used to explore the association between different CVH levels and all-cause mortality. A restricted cubic spline (RCS) curve was plotted to show the association between different CVH levels and all-cause mortality in OA patients. Hazard ratio (HR) and 95% confidence interval (CI) were calculated.ResultsFindings show that people with moderate CVH (HR = 0.67, 95% CI = 0.45—0.98) and high CVH (HR = 0.47, 95% CI = 0.26—0.87) were associated with reduced risk of all-cause mortality in patients with OA. The HR of all-cause mortality in patients with OA decreased by 0.12 as per 10 points increase of LE8 score (HR = 0.81, 95% CI = 0.73—0.90). The RCS curve revealed that the HR of all-cause mortality decreased with the increase in LE8 score. The survival probability of patients in the high CVH group was higher than the moderate CVH group and low CVH group (p = 0.002).ConclusionModerate-to-high CVH is associated with a decreased risk of all-cause mortality in patients with OA. These findings might provide a reference for the formulation of prognosis improvement strategies for the management of patients with OA.
