Life's Essential 8: Updating and Enhancing the American Heart Association's Construct of Cardiovascular Health: A Presidential Advisory From the American Heart Association

Life's Crucial 9 and NAFLD from association to SHAP-interpreted machine learning predictions

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide. Cardiovascular disease (CVD) and NAFLD share multiple common risk factors. Life's Crucial 9 (LC9), a novel indicator for comprehensive assessment of cardiovascular health (CVH), has not yet been studied in terms of its association with or predictive value for NAFLD. This study analyzed data from 10,197 participants in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018. The association between LC9 and NAFLD was assessed using weighted logistic regression, while weighted Cox proportional hazards models were applied to evaluate the relationship between LC9 and all-cause mortality among NAFLD patients. Restricted cubic spline (RCS) analysis was conducted to explore dose-response relationships, and Kaplan-Meier survival curves were utilized to examine differences in survival outcomes. Machine learning (ML) approaches were employed to construct predictive models, with the optimal model further interpreted using SHapley Additive exPlanations (SHAP). An increase of 10 points in LC9 was negatively associated with the risk of NAFLD (model 3: OR = 0.39, 95% CI = 0.36 - 0.42, P < 0.001) and all-cause mortality in NAFLD patients (model 3: HR = 0.78, 95% CI = 0.67 - 0.91, P < 0.001). A non-linear relationship was observed between LC9 and NAFLD (P < 0.0001 for nonlinearity). Among the eight ML models, the Support Vector Machine (SVM) demonstrated the best predictive performance (AUC = 0.873). SHAP analysis indicated that LC9 was the most significant predictor in the model. LC9 demonstrated a nonlinear negative association with NAFLD and a linear negative association with all-cause mortality in NAFLD patients. Maintaining a higher LC9 score may reduce the risk of NAFLD and all-cause mortality among NAFLD patients. The predictive model developed using Support Vector Machine (SVM) exhibited strong clinical predictive value, with LC9 being the most critical factor in the model, facilitating self-risk assessment and targeted intervention.

Burden of Coronary Artery Disease as a Predictor of New Vascular Events and Mortality in Patients With Ischemic Stroke: Insights From the Norwegian Stroke in the Young Study

BACKGROUND

Studies in young patients with stroke identified coronary artery disease (CAD) as a main contributor to mortality. In the present NOR-SYS (Norwegian Stroke in the Young Study), we aimed to investigate the prevalence of CAD, and the impact on new vascular events and mortality.

METHODS

A total of 385 patients with ischemic stroke, aged ≤60 years, were included. CAD was defined as a history of CAD or positive coronary imaging (computed tomography or coronary angiography).

RESULTS

Mean age was 49.6 years, and 68.1% were men. The prevalence of CAD was 25.2% (n=97) (nonobstructive, 9.6% [n=37]; and obstructive, 15.6% [n=60]). In the subsample of patients without clinical CAD but with femoral plaque on ultrasound (n=58) who underwent cardiac computed tomography, 46% (n=27) had nonobstructive CAD and 28% (n=16) had obstructive CAD. During a median follow-up of 10.1 years, 36 patients (9.4%) died, 84 (21.8%) reached a composite end point of new stroke, myocardial infarction, or death, whereas 64 (16.6%) had a composite end point of new stroke or death. Event-free survival was significantly lower in patients with obstructive CAD versus no CAD or nonobstructive CAD (log-rank P<0.001). In the multivariable Cox regression models, CAD was a strong and independent predictor of all-cause mortality (hazard ratio [HR], 2.20 [95% CI, 1.05-4.60]; P=0.037) and the composite end point of death or recurrent ischemic stroke (HR, 3.24 [95% CI, 1.46-7.20]; P=0.004).

CONCLUSIONS

In young and middle-aged ischemic stroke survivors, a quarter of patients had CAD. CAD was an independent predictor of recurrent stroke and mortality. In patients without previous CAD, but femoral plaque on ultrasound, nearly a half had nonobstructive and one-fourth had obstructive CAD. Systematic screening with cardiac computed tomography may identify high-risk patients after ischemic stroke.

Food Insecurity and Its Cardiovascular Implications in Underresourced Communities

BACKGROUND

Food insecurity is linked to poorer cardiovascular health (CVH) outcomes, particularly in underresourced communities, where social determinants of health play a critical role. Despite the recognized connections, there remains a lack of empirical evidence delineating the implications of food insecurity on CVH. CVH, a broader concept than cardiovascular disease, encompasses the overall well-being of the cardiovascular system and is supported by favorable lifestyle choices and physiological metrics. Particularly in underresourced communities, the study of CVH could provide valuable insights for early intervention and targeted public health initiatives. This study aimed to fill this knowledge gap.

METHODS AND RESULTS

We conducted a cross-sectional analysis of baseline data from the E-DUCASS (Educational Strategy on a Vulnerable Population to Improve Cardiovascular Health and Food Insecurity) program (NCT05379842), a 24-month randomized study targeting participants at risk for food insecurity. CVH was assessed using the Life's Essential 8 score. The sample included 451 participants aged 12 to 80 years, stratified by age (30.6% children [aged 12-19 years], 35.9% young adults [aged 20-39 years], and 33.5% adults [aged 40-80 years]) and sex (42.1% men and 57.9% women). The mean CVH score was 65.1 (95% CI, 63.9-66.4), with diet, physical activity, nicotine exposure, and body mass index being the lowest-scoring metrics. Food insecurity significantly influenced CVH; those participants with severe food insecurity had lower CVH scores than those without (effect size, -2.83 [95% CI, -5.10 to -0.56]; P<0.05).

CONCLUSIONS

Our findings highlight the negative association between food insecurity and CVH in underresourced Mediterranean communities. These results underscore the need for strategies aimed at reducing cardiovascular risk, potentially through health literacy programs like E-DUCASS, that focus on improving lifestyle and alleviating food insecurity.

Focusing on sleep health for all, not just sleep disorders

Sleep is increasingly recognized as a critical pillar of overall health, yet public health efforts have traditionally focused on treating sleep disorders rather than promoting sleep health for all. This article argues that the time has come to shift the emphasis from a disorder-centric approach to one that prioritizes sleep health for everyone. Sleep health extends beyond the absence of disorders and involves achieving optimal sleep quality, duration, and consistency. Poor sleep is linked to numerous health problems, including cardiovascular disease, type 2 diabetes, mental health disorders, and impaired cognitive function. Focusing on sleep health can help prevent these conditions and reduce healthcare costs. Moreover, addressing sleep health disparities, particularly among lower-income populations, shift workers, and racial and ethnic minorities, is crucial for achieving health equity. This article outlines strategies such as public awareness campaigns, workplace policies, school-based interventions, and policy advocacy to promote sleep health. By fostering a sleep-healthy society, we can improve individual and public health outcomes, enhance productivity, and reduce the economic burden associated with poor sleep. Ultimately, a comprehensive approach to sleep health offers significant benefits that extend beyond the treatment of sleep disorders, promoting a healthier and more equitable society.

Effects of combining positive psychological intervention and lifestyle intervention on improving cardiovascular health for at-risk older adults: study protocol of a Chinese multicentric community-based randomised controlled trial (ACCOMPLI-CH)

INTRODUCTION

Cardiovascular health is influenced by various factors, including not only physiological and behavioural ones but also psychological well-being. However, when developing comprehensive preventive approaches, psychological interventions often receive less attention, despite their possible multiple mechanisms on cardiovascular health. Incorporating both healthy behaviour and psychological well-being promotion would be a more efficacious preventive approach. This study aims to investigate the effects of a community-based multicomponent intervention combining positive psychological intervention and lifestyle intervention on improving cardiovascular health among older adults with risk factors of cardiovascular diseases.

METHODS AND ANALYSIS

This study is a multicentre, community-based, randomised controlled trial with 18 months of intervention and follow-up for community-dwelling older adults aged 60 years and above with risk factors for cardiovascular health. Intervention activities last 6 months and are composed of in-person group training sessions of 60-80 min led by trained group instructors and weekly self-monitoring homework. Participants are randomly assigned to a multicomponent intervention 'Harmony' group (24 sessions of positive psychology and lifestyle intervention delivered weekly), an active control 'Lifestyle' group (eight sessions of lifestyle intervention delivered every 3-4 weeks) or a waitlist control group (no intervention activities). Positive psychological training sessions are designed using well-known techniques derived from positive psychology theories with adaptations to Chinese culture, and lifestyle training sessions are developed according to national guidelines. The primary outcome includes the change of a composite score of systolic blood pressure, total cholesterol, high-density lipoprotein and low-density lipoprotein levels, as well as psychological well-being measured from three perspectives, including hedonic, eudaimonic and evaluative well-being. Secondary assessments include other measures for physical and biological indicators, psychological well-being, health behaviours, social connection factors and overall cognitive functions. Primary data analyses will follow the intention-to-treat principle. To examine the effects of intervention, multilevel mixed models will be performed. In case of any differences in baseline participant characteristics, they will be adjusted for as covariates.

ETHICS AND DISSEMINATION

A centralised ethics review process was conducted, and the study protocol was approved by the ethics committee of the Institutional Review Board of the Institute of Psychology, Chinese Academy of Sciences in April 2022. A signed written informed consent form will be obtained from all participants. On completion, the trial results will be disseminated through published manuscripts and presentations at scientific conferences.

Life's Essential 8 and risks of mortality and cardiovascular morbidity in individuals with PRISm and its associations with transition trajectories of PRISm

BACKGROUND

Although morbidity and mortality are reportedly increased in individuals with preserved ratio impaired spirometry (PRISm), little is known about how to optimise PRISm-related health.

AIMS

Is Life's Essential 8 (LE8) associated with mortality and cardiovascular morbidity in individuals with PRISm and with PRISm transition trajectories?

METHODS

Participants with PRISm (n=31 943) with complete data on LE8 and 23 179 individuals with two spirometry measurements were included from the UK Biobank. Eight health components were used to create the LE8 score (0-100). Cox proportional hazards models were used to assess associations of LE8 with cardiovascular morbidity and all-cause, cardiovascular and respiratory mortality. Multinomial logistic regression models were conducted to assess associations between LE8 and transition trajectories of PRISm.

RESULTS

Among participants with PRISm, 3113 (9.75%), 25 254 (79.06%) and 3576 (11.19%) were categorised as high (LE8≥80), moderate (50≤LE8<80) and low LE8 (LE8<50) score groups, respectively. Compared with the high LE8 group, the low LE8 group demonstrated higher risks of cardiovascular disease (HR: 2.702, 95% CI 2.391 to 3.054) and all-cause (2.496, 2.082 to 2.993), cardiovascular (4.165, 2.672 to 6.493) and respiratory mortality (4.103, 1.866 to 9.020). Individuals with low LE8 score (vs high LE8) had higher odds to transition from normal spirometry to PRISm (OR: 2.238, 95% CI 1.638 to 3.057) and lower odds to transition from PRISm to normal spirometry (OR: 0.506, 95% CI 0.339 to 0.757).

CONCLUSION

A lower LE8 score was associated with increased risks of cardiovascular morbidity and all-cause, cardiovascular and respiratory mortality in PRISm. A lower LE8 score was related to higher likelihood of developing PRISm and lower likelihood of PRISm recovery.

Association of Life's Crucial 9 with all-cause and cardiovascular mortality in stroke survivors and predictive value for mortality compared with Life's Essential 8: evidence from NHANES 2005-2018

Background

There is evidence of a positive correlation between depressive disorders and poor cardiovascular health (CVH). Recently, the inclusion of psychological health assessments into Life's Essential 8 (LE8) has been put forward to enhance the foundation of CVH. We aimed to investigate the probable link between the innovative CVH assessment framework, Life's Crucial 9 (LC9), and overall mortality as well as mortality associated with cardiovascular disease (CVD) among stroke survivors, while also assessing its prognostic relevance regarding mortality in comparison to LE8.

Methods

This study draws on a cohort of stroke survivors identified from the National Health and Nutrition Examination Survey (NHANES), spanning survey cycles from 2005 to 2018. The LE8 was assessed by the approach recommended by the American Heart Association. The LC9 framework incorporated an additional depression score, measured by Patient Health Questionnaire-9, into the LE8 assessment. To investigate the associations between LE8 and LC9 with all-cause and cardiovascular mortality in stroke survivors, we employed multivariable Cox proportional hazards regression analyses.

Results

After adjusting for covariates, each 10-point increase in LC9 was associated with a 24.5 and 30.1% reduction in all-cause and CVD mortality in stroke survivors, respectively. Participants in the highest quartile (Q4) of LC9 exhibited significantly lower mortality rates compared to those in the lowest quartile (Q1) (all-cause mortality: HR 0.412, p < 0.0001; CVD mortality: HR 0.327, p < 0.001). Similar associations were observed for LE8. Restricted cubic spline analysis indicated that both LC9 and LE8 demonstrated linearly associations with mortality post-stroke. Physical activity score, nicotine exposure score, and blood glucose score were significantly linked to all-cause and CVD mortality in stroke survivors. Adding depression score to LE8 significantly enhanced the prediction of all-cause mortality in stroke survivors (net reclassification improvement index = 9.6%, p = 0.033; ΔC index = 0.002, p = 0.0009; integrated discrimination improvement = 0.01, p = 0.007). The NRI of 9% (p = 0.086) for CVD mortality, while not statistically significant, suggests a trend toward improved classification.

Conclusion

LC9 exhibited both linear and inverse correlations with all-cause and cardiovascular mortality among stroke survivors. Adding a depression score to the LE8 framework may improve the predictive accuracy for all-cause mortality in stroke survivors.

Assessing the impact of volatile organic compounds on cardiovascular health: Insights from the National Health and Nutrition Examination Survey 2011-2020

Volatile organic compounds (VOCs) are environmental pollutants that may negatively impact cardiovascular health. This study investigates the association between VOC mixtures, measured through urinary VOC metabolites (VOCMs), and cardiovascular health using Life's Essential 8 (LE8) scores. Data from the National Health and Nutrition Examination Survey (NHANES) 2011-2020 were analyzed for 2967 adults aged 20-79 years. Multiple statistical methods, including correlation analysis, variance inflation factor (VIF) analysis, quantile g-computation (q-gcomp), and Bayesian kernel machine regression (BKMR), were applied to assess the association between VOCMs and LE8 scores. Sensitivity analyses were conducted with different random seeds and subsampling techniques to confirm robustness. Correlation and VIF analyses revealed strong collinearity among VOCMs, highlighting the need for advanced models. Survey-weighted regression indicated that lower VOC exposure was associated with better cardiovascular health. Q-gcomp identified both positive and negative associations between individual VOCMs and LE8 scores, with some unexpected positive associations. BKMR highlighted the complex mixture effects of VOCMs on cardiovascular health. Sensitivity analyses confirmed the consistency of these findings. This study underscores the intricate relationship between VOC exposure and cardiovascular health and the necessity of advanced statistical methods for mixture analysis. Despite some unexpected findings, the results suggest that VOC exposure, as reflected by urinary VOCMs, is associated with adverse cardiovascular health outcomes. Further research is needed to clarify the biological mechanisms and implications of these associations.

Inverse associations of the lifestyle critical 9 with cardiorenal syndrome: the mediating role of the dietary inflammatory index

Background

Cardiorenal syndrome (CRS) represents a burgeoning global health concern characterized by its increasing prevalence. Life's Crucial 9 (LC9), an innovative tool for cardiovascular health assessment, and the Dietary Inflammatory Index (DII), which quantifies diet's impact on body inflammation, have not been previously studied in conjunction regarding their association with CRS.

Objective

This study aims to explore the relationship between LC9 and CRS, using data from the National Health and Nutrition Examination Survey (NHANES), and to examine whether DII serves as a mediator in this association.

Methods

This research included data from 25,792 NHANES participants spanning from 2005 to 2018. The study leverages the dataset's comprehensive representativeness and robust statistical power to ensure generalizable and reliable findings. We employed weighted logistic regression to evaluate the association between LC9 scores and CRS presence, conducted subgroup analyses, and performed mediation analysis to investigate the role of DII.

Results

Our analysis demonstrated a significant inverse relationship between LC9 and CRS. Upon controlling for confounders, each 10-point rise in LC9 correlates with a 26% reduction in CRS prevalence (p < 0.001). Additionally, stratifying LC9 into tertiles with T1 as the reference group revealed that T2 (OR = 0.59, 95% CI = 0.48-0.72, p < 0.001) and T3 (OR = 0.57, 95% CI = 0.38-0.88, p < 0.001) exhibited a strong negative correlation trend. The dose-response curve illustrates a linear relationship between LC9 and CRS; as LC9 increases, the occurrence of CRS decreases. DII shows a significant positive connection with CRS (p < 0.001), but DII indicates a decreasing trend when LC9 rises (β = -0.65, p < 0.001). Mediation analysis reveals that DII mediates the association between LC9 and CRS, with a mediation proportion of 12.5% (p < 0.001).

Conclusion

The findings indicate a robust inverse correlation between LC9 scores and CRS incidence, with DII is associated with this relationship. This suggests potential preventive strategies against CRS through lifestyle modifications guided by LC9.

Association between cardiovascular health and markers of liver function: a cross-sectional study from NHANES 2005-2018

Background

Cardiovascular health (CVH) has been associated with various systemic diseases. However, the relationship between CVH, as measured by Life's Essential 8 (LE8), and liver function markers in the general population remains poorly understood.

Methods

This study analyzed data from 21,156 participants (aged ≥ 20) from the NHANES 2005-2018 to investigate the associations between CVH and liver function markers [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), albumin and AST/ALT ratio]. Linear regression models were used, along with a restricted cubic spline (RCS) to assess dose-response. Weighted quantile sum (WQS) regression and quantile g-computation (QGC) analyses were employed to evaluate the association between CVH and liver function markers.

Results

Linear regression analysis showed that each 1-point increase in CVH score was significantly associated with decreased levels of liver enzymes [ALT: -0.200 U/L (95% CI: -0.223, -0.176), AST: -0.043 U/L (-0.062, -0.024), GGT: -0.453 U/L (-0.509, -0.397), ALP: -0.310 U/L (-0.340, -0.281)] and increased levels of albumin [0.040 g/dL (0.036, 0.045)] and AST/ALT ratio [0.0056 (0.0051, 0.0061)]. Notably, CVH score demonstrated non-linear dose-response relationships with ALT, ALP, and AST/ALT ratio. Age significantly modified these associations, while nicotine exposure, BMI, and blood lipids were identified as primary contributors through WQS and QGC analyses. E-value analysis suggested robustness to unmeasured confounding.

Conclusion

This study demonstrates robust associations between CVH and liver function markers in United States adults, with nicotine exposure, BMI, and blood lipids identified as significant contributors. These findings suggest that maintaining optimal cardiovascular health may have beneficial effects on liver function, highlighting potential targets for integrated prevention strategies.

Insights into associations between Life's essential 8 and lung function from NHANES data

The Life's Essential 8 (LE8) is a novel indicator of cardiovascular health proposed by the American Heart Association. While numerous studies have demonstrated its guiding value in chronic diseases, research on its role in lung function remains limited. This study utilized data from the National Health and Nutrition Examination Surveys (NHANES 2007-2012), which included comprehensive measurements of lung function, diet, physical activity, nicotine exposure, sleep patterns, body mass index (BMI), blood glucose, blood pressure, blood lipids, and relevant covariates. We calculated lung function Z-score and LE8 scores, employing multiple linear regression, multivariable logistic regression, and restricted cubic spline models to evaluate their correlations. In this study of 10,400 participants (mean age 44 years; 48.75% male), participants were classified into threeforcedexpiratory volume in one second (FEV1) Z-score groups: Z1 (normal lung function, n = 9,600), Z2 (mild impairment, n = 618), and Z3 (moderate to severe impairment, n = 182). Significant differences in demographic characteristics and health parameters were observed among the groups. Notably, variations in the Healthy Eating Index 2015 (HEI-2015), physical activity, nicotine exposure, and sleep patterns were identified within the LE8 health behavior domain. Higher LE8 scores were found to be positively associated with lung function, even after adjusting for demographic and health factors. Further analysis revealed positive correlations between lung function and favorable dietary habits, higher physical activity levels, reduced nicotine exposure, and improved sleep quality. Conversely, BMI, blood lipids, blood glucose, and blood pressure exhibited variable effects. Subgroup and sensitivity analyses consistently supported findings, confirming a positive correlation between LE8 and lung function. Our study highlights significant associations between LE8 scores and lung function, demonstrating that higher LE8 scores, which reflect better cardiovascular health behaviors, are positively correlated with improved lung function.

Can cardiovascular health and its modifiable healthy lifestyle offset the increased risk of all-cause and cardiovascular deaths associated with insulin resistance?

BACKGROUND

Insulin resistance(IR) is associated with an increased risk of all-cause and cardiovascular death, and modifiable healthy lifestyles play an active role in the improvement of IR and the reduction of all-cause and cardiovascular death. Whether cardiovascular health (CVH) and modifiable healthy lifestyles within it can attenuate or even offset the heightened perils of both all-cause and cardiovascular deaths associated with insulin resistance remains unclear.

METHODS

The study encompassed 14,172 healthy participants from the 2005-2018 NHANES programme. Insulin resistance was evaluated using the TyG index, TyG-WC, and TyG-WHtR, while CVH was assessed employing the LE8 score, in addition to the LE4 index redefined according to four health behaviours. Weighted multifactor Cox regression models were used to assess the association of IR and CVH with all-cause and cardiovascular mortality, and dose-response relationships were assessed using restricted cubic spline. Furthermore, subjects were grouped according to IR and CVH scores, and generalised linear models were used to estimate the weighted mortality and risk of death for each group and to calculate the absolute risk difference. Finally, the predicted probability of all-cause and cardiovascular mortality risk as a function of IR was computed, and the complex relationship between the three was visualised using two-dimensional grouped scatter plots and three-dimensional surface plots.

RESULTS

Among the 14,172 healthy participants included in the study, 1534 deaths occurred over a mean follow-up period of 7.6 years (382 of these deaths were due to cardiovascular causes). The weighted Cox regression analysis indicated that elevated TyG-WC and TyG-WHtR correlated with a greater likelihood of mortality from all causes and cardiovascular events, whereas cardiovascular health was inversely associated with these risks. Additional stratification revealed a notable reduction in the likelihood of mortality from all causes and cardiovascular events as cardiovascular health improved, irrespective of the presence of insulin resistance. Additionally, participants with high insulin resistance but moderate or high cardiovascular health did not have significantly increased risks compared with those with low insulin resistance. Stratified scatter plots and 3D surface plots revealed that cardiovascular health and modifiable healthy lifestyles significantly reduced the risk of insulin resistance-related death, with greater reductions observed at higher insulin resistance levels.

CONCLUSIONS

In this cohort study, improving cardiovascular health and modifiable health behaviors significantly reduced the risk of insulin resistance-related all-cause and cardiovascular deaths. Maintaining cardiovascular health at moderate or high levels (LE8 ≥ 50) could offset the increased risks caused by insulin resistance.

Sleep regularity and major adverse cardiovascular events: a device-based prospective study in 72 269 UK adults

BACKGROUND

This study examines the associations between device-measured sleep regularity and the risk of major adverse cardiovascular events (MACE), and aims to determine whether sufficient sleep duration attenuates or eliminates the effects of irregular sleep on MACE risk.

METHODS

A prospective cohort study of adults aged 40-79 years from the UK Biobank who wore wrist-attached accelerometers for 7 days was conducted. Sleep Regularity Index (SRI) scores were calculated for each participant using a validated algorithm, and categorised as irregular (SRI <71.6), moderately irregular (SRI between 71.6 and 87.3), and regular (SRI >87.3 (reference group)). Information on MACE and its subtypes (myocardial infarction, heart failure, stroke) was obtained from inpatient hospitalisation and death records.

RESULTS

We analysed data from 72 269 individuals followed for 8 years, without a previous history of MACE and without an event in the first year of follow-up. Irregular (HR 1.26, 95% CI 1.16 to 1.37) and moderately irregular sleepers (HR 1.08, 95% CI 1.01 to 1.70) were at higher risk of MACE compared with regular sleepers. Dose-response analyses treating SRI as a continuous measure showed that SRI was associated with MACE risk in a near-linear fashion, with a steeper MACE risk reduction at higher (better) SRI scores. Joint SRI and sleep duration analyses showed that meeting the age-specific sleep duration recommendation offsets MACE risk for moderately irregular sleepers (HR 1.07, 95% CI 0.96 to 1.18), but not for irregular sleepers (HR 1.19, 95% CI 1.06 to 1.35).

CONCLUSIONS

Irregular sleep was strongly associated with higher MACE risk. Adequate sleep duration was not sufficient to offset these adverse effects among irregular sleepers. This study supports the inclusion of sleep regularity in public health guidelines and clinical practice as a risk factor for cardiovascular disease.

Association of polysocial risk score, cardiovascular health status, and the risk of premature mortality: Findings from the UK Biobank

BACKGROUND

Evidence of the cumulative effects of social risk factors on premature mortality is quite limited. We aimed to examine the association between cumulative social risk factors and premature mortality by constructing a polysocial risk score, and to explore the influence of cardiovascular health on this association.

METHODS

A polysocial risk score was constructed by summing 11 social determinants of health. A cardiovascular health (CVH) score was calculated following the algorithm of "Life's Essential 8". Premature mortality was defined as death at an age younger than 75. Cox proportional hazards model was conducted.

RESULTS

A total of 314,039 participants in the UK Biobank were included (median age 56.0 years, 53.1% women). During a median of 12.7 years of follow-up, 13,888 premature deaths were reported. Compared with participants who had a low polysocial risk score (≤3), participants with a high polysocial risk score (≥7) were more than twice as likely to die prematurely in the follow-up period (HR 2.18, 95% CI 2.06-2.30). Compared with participants with ideal CVH and low polysocial risk score, those with poor CVH and high polysocial risk score had the highest risk of premature mortality (HR 5.25, 95% CI 4.48-6.14). A significant interaction was found between CVH status and polysocial risk score on premature mortality risk (P for interaction <0.001).

CONCLUSIONS

Polysocial risk score was associated with an increased risk of premature mortality, the association was exacerbated by poor CVH. Our findings indicate that limiting social inequities and encouraging people to achieve an ideal CVH are essential to reducing the burden of premature mortality.

Association between life's crucial 9 and kidney stones: a population-based study

Purpose

This study examined the association between the Life's Crucial 9 (LC9) score and kidney stone prevalence in U.S. adults.

Methods

Using data from the National Health and Nutrition Examination Survey (NHANES) spanning 2007 to 2014, this cross-sectional analysis focused on adult participants with kidney stone onset or recurrence. LC9 scores were divided into four quartiles for analysis. Weighted multivariable logistic regression, restricted cubic spline (RCS) modeling, threshold effect analysis, and subgroup analyses were employed to evaluate the relationship between LC9 scores and kidney stone prevalence.

Results

The study included 24,669 participants with an average age of 46.05 ± 0.34 years and a mean LC9 score of 73.76 ± 0.25. The overall prevalence of kidney stones was 8.45%, while the average recurrence rate stood at 2.96%. Importantly, for each one-point increase in the LC9 score, the incidence of kidney stones dropped by 1.2% (95% CI: 0.979 to 0.997, p = 0.014). Compared to the lowest quartile (Q1), the Q4 group exhibited a 0.305-fold higher recurrence rate (95% CI: 0.159 to 0.586, p < 0.001). Interaction analysis showed that race and gout significantly influenced the relationship between the LC9 score and kidney stone risk. Additionally, curve fitting and threshold effect analysis demonstrated a nonlinear association between LC9 scores and kidney stone recurrence, with a breakpoint identified at 72.777.

Conclusion

An elevated LC9 score correlates with a lower risk of both kidney stone formation and recurrence. Maintaining an optimal LC9 score could be an effective approach for preventing kidney stones.

Association between behavioural risk factors for hypertension and concordance with the Dietary Approaches to Stop Hypertension dietary pattern among South Asians in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study

South Asians are among the fastest-growing immigrant population group in the United States (U.S.) with a unique disease risk profile. Due in part to immigration and acculturation factors, South Asians engage differently with behavioural risk factors (e.g. smoking, alcohol intake, physical activity, sedentary behaviour, and diet) for hypertension, which may be modified for the primary prevention of cardiovascular disease. Using data from the Mediators of Atherosclerosis in South Asians Living in America cohort, we conducted a cross-sectional analysis to evaluate the association between behavioural risk factors for cardiovascular disease and diet. We created a behavioural risk factor score based on smoking status, alcohol consumption, physical activity, and TV watching. We also calculated a Dietary Approaches to Stop Hypertension (DASH) dietary score based on inclusion of relevant dietary components. We used both scores to examine the association between engaging with risk factors for hypertension and the DASH diet among a cohort of South Asian adults. We found that participants with 3-4 behavioural risk factors had a DASH diet score that was 3 units lower than those with no behavioural risk factors (aβ: -3.25; 95% CI: -4.28, -2.21) and were 86% less likely to have a DASH diet score in the highest category compared to the lowest DASH diet score category (aOR: 0.14; 95% CI: 0.05, 0.37) in the fully adjusted models. These findings highlight the relationship between behavioural risk factors for hypertension among South Asians in the U.S.

Effect of Daily Avocado Intake on Cardiovascular Health Assessed by Life's Essential 8: An Ancillary Study of HAT, a Randomized Controlled Trial

BACKGROUND

The effect of single food-based dietary interventions on the American Heart Association's cardiovascular health score, Life's Essential 8 (LE8), is unclear. The aim of this study was to examine the effect of daily avocado intake for 26 weeks on LE8 in adults with abdominal obesity.

METHODS AND RESULTS

An ancillary analysis including participants (n=969; aged 51±14 years) from the HAT (Habitual Diet and Avocado Trial), a randomized controlled trial, was conducted. The Avocado-Supplemented Diet Group was provided with 1 avocado per day, and the Habitual Diet Group was instructed to maintain their usual diet. LE8 component scores (diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids, blood glucose, and blood pressure) were calculated using a modified American Heart Association algorithm. The LE8 score was calculated as the unweighted average of each component (range, 0-100 points). Between-group differences in the 26-week change in LE8 were assessed using general linear models. No significant between-group difference in the 26-week change in the LE8 score from baseline was observed (0.79 points [95% CI, -0.41 to 2.00]). However, avocado intake increased the LE8 component scores for diet (3.53 points [95% CI, 1.38-5.68]), sleep health (3.20 points [95% CI, 0.38-6.02]), and blood lipids (3.46 points [95% CI, 1.03-5.90]) compared with the Habitual Diet Group.

CONCLUSIONS

Intake of 1 avocado per day for 26 weeks did not significantly affect the total cardiovascular health score in US adults with abdominal obesity. However, diet quality, sleep health, and blood lipids improved with daily avocado intake.

Evaluating the Reliability and Robustness of Racial and Ethnic Health Disparities in Cardiometabolic Disease in NHANES, NHIS, and BRFSS (2015-2021)

BACKGROUND

The United States uses the National Health Interview Survey (NHIS), Behavioral Risk Factor Surveillance System (BRFSS), and National Health and Nutrition Examination Survey to monitor disease trends and inform clinical care/prevention research. These 3 surveys share similar national estimates. However, the consistency of each survey's estimates by race has not been examined. Here, we compare prevalence estimates and disparities in cardiometabolic diseases across 5 aggregated racial and ethnic groups.

METHODS

We examined the age- and fully-adjusted prevalence of cardiovascular disease and diabetes among non-Hispanic White, non-Hispanic Black, Hispanic, non-Hispanic Asian, and "Other" race respondents aged 30 years or older. Cardiovascular disease included self-reported physician diagnosis of heart attack, stroke, and coronary heart disease.

RESULTS

Although overall national population estimates were similar, there was heterogeneity in estimates by survey. For heart attack and diabetes, each racial group had a higher prevalence in BRFSS than NHIS (eg, Heart Attack: Hispanic BRFSS: 3.4% [95% CI, 3.2-3.6], NHIS: 2.0% [95% CI, 1.8, 2.2]; non-Hispanic Black BRFSS: 3.8% [95% CI, 3.6, 3.9]; NHIS: 3.0% [95% CI, 2.7, 3.2]). Non-Hispanic Asian people had the lowest general cardiovascular disease prevalence across all 3 data sets (NHIS: 5.9%, National Health and Nutrition Examination Survey: 5.3%, BRFSS: 6.9%), while Other/multi-racial respondents had the highest prevalence (NHIS: 9.9%, National Health and Nutrition Examination Survey: 13.1%, BRFSS: 10.7%). However, the magnitude of these differences across data sets was small.

CONCLUSIONS

Prevalence estimates for heart attack and diabetes were heterogeneous by race across surveys. These results highlight the importance of improving the representation of racially minoritized groups within national surveys to produce more precise estimates.

The Puerto Rico Young Adults' Stress, Contextual, Behavioral, and Cardiometabolic Risk (PR-OUTLOOK) Study: design and methods

The Puerto Rico (PR) Young Adults' Stress, Contextual, Behavioral and Cardiometabolic Risk Study (PR-OUTLOOK) is investigating overall and component-specific cardiovascular health (CVH) and cardiovascular disease (CVD) risk factors in a sample of young Puerto Rican adults (aged 18-29 years) in PR (target n = 3000) and examining relationships between individual-, family- or social-, and neighborhood-level stress and resilience factors and CVH and CVD risk factors. The study researchers are conducting standardized measurements of CVH and CVD risk factors and demographic, behavioral, psychosocial, neighborhood, and contextual variables and establishing a biorepository of blood, saliva, urine, stool, and hair samples. The assessment methods are aligned with other National Heart, Lung, and Blood Institute-funded studies: the Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic Disease Trends of adults aged 30-75 years; the Hispanic Community Health Study/Study of Latinos; the Boston Puerto Rican Health Study; and the Coronary Artery Risk Development in Young Adults. PR-OUTLOOK data and the study biorepository will facilitate future longitudinal studies of the temporality of associations between stress and resilient factors and CVH and CVD risk factors among young Puerto Ricans. These resources have potential for advancing the scientific understanding of these conditions in a high-risk but understudied young population.

Optimizing Psychological Health Across the Perinatal Period: An Update on Maternal Cardiovascular Health: A Scientific Statement From the American Heart Association

Perinatal psychological health conditions (eg, perinatal depression, anxiety) are some of the leading causes of maternal mortality in the United States and are associated with adverse pregnancy outcomes, long-term cardiovascular outcomes, and intergenerational effects on offspring neurodevelopment. These risks underscore the importance of addressing maternal psychological health as a key determinant of perinatal cardiovascular health. Thus, it is vital to recognize the spectrum of perinatal psychological health and to provide guidance for both patients and clinicians on screening and management options across the perinatal period. In this scientific statement from the American Heart Association, we redefine maternal cardiovascular health to include psychological health, provide robust evidence on the association of psychological health with cardiovascular outcomes, highlight the social and environmental underpinnings, and finally, offer guidance about how to integrate psychological health into maternal cardiovascular health with a specific focus on the perinatal period (ie, pregnancy through 1 year postpartum). We also describe opportunities for creating care delivery models that recurrently address perinatal psychological health in cardio-obstetric care, using behavioral and pharmacological interventions, with an emphasis on better integration of psychological health care, longer postpartum follow-up, and opportunities for evaluating the comparative effectiveness of these models with stakeholder partners.

Role of Cardiovascular Health in the Bidirectional Progression Trajectories Between Cardiovascular Disease, Type 2 Diabetes, and Cancer

BACKGROUND

There existed bidirectional associations of cardiovascular disease (CVD) and type 2 diabetes (T2D) with cancer, partly attributed to their shared risk factors. We aimed to explore the role of cardiovascular health (CVH) in bidirectional transitions between CVD, T2D, and cancer.

METHODS

Based on the UK Biobank, we used 2 subcohorts: a disease-free cohort of 277 997 individuals without cancer, CVD, and T2D; and a disease survivor cohort consisting of 61 971 cases with cancer, CVD, and T2D at baseline. The CVH was assessed on the basis of Life's Essential 8 score. We conducted the multistate model and Cox proportional hazards model to explore the role of CVH in bidirectional transitions between CVD, T2D, and cancer in disease-free and disease survivor cohorts, respectively.

RESULTS

High CVH was significantly associated with a lower transition risk from CVD to cancer (hazard ratio, 0.822 [95% CI, 0.693-0.975]). On the other hand, increased CVH was related to reduced risks of progression from cancer to CVD and T2D (both P for trend<0.001), particularly in the high CVH group. For disease survivor cohorts, per 10-point increase in CVH was associated with >10% lower cancer risk in CVD and T2D cases, and a 16% and 42% reduction in the risk of incident CVD and T2D among cancer survivors, respectively.

CONCLUSIONS

High CVH was related to a decreased risk of bidirectional transitions between CVD, T2D, and cancer. This highlighted the significance of maintaining high CVH throughout the life span for the primary prevention of CVD, T2D, and cancer.

The impact of social determinants of health on chronic kidney disease risk: evidence from the CHARLS study

Background

Empirical evidence regarding the relationship between social determinants of health (SDH) and renal outcomes remains limited. Consequently, the objective of this study was to investigate the potential association between SDH and the development of chronic kidney disease (CKD) across various levels.

Methods

Data were sourced from the 2011 China Health and Retirement Longitudinal Study (CHARLS), which included 6,290 Chinese participants aged 40 years and older. Among these participants, 4,115 underwent a follow-up assessment in the 2015 survey. The primary outcome measure was the incidence of CKD, operationally defined as a reduction in estimated glomerular filtration rate to <60 ml/min/1.73 m2. To analyze the association between varying levels of SDH and renal outcomes, a Cox proportional hazards regression model was employed.

Results

The findings indicate that, in comparison to individuals with a pension, higher education, and no need for family support, the risk of developing CKD increased by 43, 49, and 52%, respectively. Furthermore, the combination of requiring family support, being unmarried, and lacking medical insurance was associated with an elevated incidence of CKD. Utilizing the counting model of adverse SDH indicators, it was observed that when the number of adverse SDH was equal to or greater than four, there was a significant increase in the risk of CKD. The incidence density of CKD was found to rise in correlation with the severity of adverse SDH, with the incidence density in the adverse SDH group being 0.06 per person-year higher than that in the favorable SDH group. After adjusting for multiple variables, the hazard ratio (HR) for incident CKD was 2.47 [95% confidence interval (CI): 1.46-4.16] in the adverse SDH group compared to the favorable SDH group, a finding that persisted across various subgroups.

Conclusion

Research indicates that financial support, pensions, education, marital status, and health insurance significantly impact CKD risk. Higher income, pension coverage, education, marital stability, and insurance lower this risk. Evaluating adverse SDH indicators helps assess individual SDH levels and CKD risk, with four or more indicators suggesting high risk. Therefore, adverse SDH measures can predict CKD.

Non-HDL Cholesterol May Be Preferred over Apolipoprotein B-100 for Risk Assessment when Evaluated by Receiver Operator Characteristic Curve Analysis

BACKGROUND

Most studies found that apolipoprotein B (apo B)-100 is a superior marker for coronary risk to non-high-density lipoprotein (HDL) cholesterol (C). Usually, studies use multivariant analysis with single-point odds/risk ratios. In multivariant analysis, when variables are highly correlated they are difficult to interpret. Effects cannot be well discriminated.

METHODS

Brief review and examination of diagnostic sensitivity and specificity by receiver operator characteristic (ROC) curves at decision levels so that discrimination can be well compared. Since apo B has additional expense, clinical value should be compared in an appropriate format. Apo B and cholesterols were measured in 382 angiographically defined patients.

RESULTS

Non-HDLC and apo B were stronger markers than low-density lipoprotein (LDL)C, when examined by logistic regression, but as a result of strong collinearity, non-HDLC appeared weaker than LDLC in the presence of apo B, based on P values. This was true when analyzed with and without nonlipid risk factors. On ROC analysis, apo B and non-HDLC showed stronger C statistics than LDLC and total C. When analyzed alone apo B showed about 6.1% greater sensitivity than non-HDLC. After adjustment for nonlipid risk factors, the C statistics for apo B and non-HDLC were 0.74 and 0.73, and there was little difference in diagnostic specificity.

CONCLUSIONS

Risk is calculated from an algorithm that includes nonlipid risk factors similar to those examined here along with cholesterols. When assessed by the 10-year screening algorithm, these data support the view that non-HDLC would be less expensive than apo B with similar clinical efficacy.

Non-traditional risk factors for atrial fibrillation: epidemiology, mechanisms, and strategies

Atrial fibrillation (AF) has become the pre-dominant arrhythmia worldwide and is associated with high morbidity and mortality. Its pathogenesis is intricately linked to the deleterious impact of cardiovascular risk factors, emphasizing the pivotal imperative for early detection and mitigation strategies targeting these factors for the prevention of primary AF. While traditional risk factors are well recognized, an increasing number of novel risk factors have been identified in recent decades. This review explores the emerging non-traditional risk factors for the primary prevention of AF, including unhealthy lifestyle factors in current society (sleep, night shift work, and diet), biomarkers (gut microbiota, hyperuricaemia, and homocysteine), adverse conditions or diseases (depression, epilepsy, clonal haematopoiesis of indeterminate potential, infections, and asthma), and environmental factors (acoustic pollution and other environmental factors). Unlike traditional risk factors, individuals have limited control over many of these non-traditional risk factors, posing challenges to conventional prevention strategies. The purpose of this review is to outline the current evidence on the associations of non-traditional risk factors with new-onset AF and the potential mechanisms related to these risk factors. Furthermore, this review aims to explore potential interventions targeting these risk factors at both the individual and societal levels to mitigate the growing burden of AF, suggesting guideline updates for primary AF prevention.

Sleep traits causally affect epigenetic age acceleration: a Mendelian randomization study

Sleep disorders (SDs) are a common issue in the elderly. Epigenetic clocks based on DNA methylation (DNAm) are now considered highly accurate predictors of the aging process and are associated with age-related diseases. This study aimed to investigate the causal relationship between sleep traits and the epigenetic clock using Mendelian randomization (MR) analysis. The genome-wide association study (GWAS) statistics for epigenetic clocks (HannumAge, intrinsic epigenetic age acceleration [IEAA], PhenoAge, and GrimAge) and sleep traits were obtained from the UK Biobank (UKB), 23andMe and Finngen. Moreover, crucial instrumental variables (IVs) were evaluated. Inverse variance weighted (IVW), MR-Egger, weighted median (WM), weighted mode, and simple mode methods were employed to assess the causal relationship between them. Multiple analyses were performed for quality control evaluation. Our study showed that self-reported insomnia may speed up the aging process by GrimAge clock, while GrimAge acceleration could faintly reduce self-reported insomnia. Epigenetic clocks mainly influence sleep traits by PhenoAge and GrimAge with weak effects. This may indicate that early interventions of SDs could be a breaking point for aging and age-related diseases. Further studies are required to elucidate the potential mechanisms involved.

Association of mid-age Life's Essential 8 score with digital cognitive performance and incident Alzheimer's disease: The Framingham Heart Study

BackgroundCardiovascular health (CVH) is a modifiable risk factor for Alzheimer's disease (AD). However, studies examining the association between mid-age CVH, as indicated by Life's Essential 8 (LE8) health metrics, and digital cognitive performance or AD risk are limited.ObjectiveTo examine the associations between mid-age CVH, assessed by LE8 scores during ages 45 to 65, and digital Clock Drawing Test (dCDT) performance as well as the incidence of AD.MethodsWe included 1198 participants (51.6% women) from the Framingham Heart Study (FHS) Offspring cohort. Linear regression and Cox proportional hazards models were applied to examine the associations between mid-age CVH and dCDT performance, as well as the incidence of AD.ResultsOver a median follow-up of 17.5 years, 45 participants developed AD. Each standard deviation (SD) higher mid-age LE8 total score was associated with a 0.16 SD higher level of the dCDT total score (p < 0.001) and a 0.35-fold lower risk of incident AD (HR = 0.65, 95% CI: 0.49-0.87, p = 0.003). The dCDT measures showed stronger associations with mid-age LE8 and AD risk compared to the conventional CDT (cCDT). For example, the drawing score on copy tasks was more strongly associated with LE8 (beta = 0.10, p = 0.007 versus beta = 0.08, p = 0.27) and had higher discrimination for incident AD (C-statistic = 0.89 versus 0.83) compared to the cCDT.ConclusionsOur results highlight the potential of digital cognitive assessments for evaluating AD risk and emphasize the importance of mid-age CVH in shaping cognitive outcomes and the development of AD.

Relationship between LE8 score and peripheral arterial disease from NHANES perspective

Background: This study examined the link between the Life's Essential 8 (LE8) metric and peripheral artery disease (PAD) prevalence in the U.S. Patients and methods: This population-based prospective cohort study analyzed data from 6,076 participants aged 20 years and older from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004. LE8 scores were categorized into low, moderate, and high cardiovascular health (CVH) levels. Multivariable weighted logistic regression and subgroup analyses were performed to examine the relationship between CVH and PAD, adjusting for demographic and clinical variables. Results: In final analysis, a total of 6,076 individuals were included, with a mean age of 59.41±12.80 years and 51.3% (n=3,115) being male. The prevalence of PAD was 6.9% (n=418). After adjusting for confounding factors, compared to participants with low CVH, those with moderate CVH had a 34% lower risk of PAD (OR: 0.66, 95% CI: 0.53-0.82), and those with high CVH had a 62% lower risk of PAD (OR: 0.38, 95% CI: 0.25-0.58). Conclusions: In conclusion, we report that lower CVH scores are associated with higher PAD risk among U.S. adults. These findings may contribute to the prevention strategies for PAD.

Impacts of temperature and solar radiation changes in northern Europe on key population health behaviors: a scoping review of reviews

AIM

Climate change threatens health directly as well as indirectly through impacts on health-related behaviors. Physical activity, nutrition and sleep are key health-related behaviors for population health. We aimed at elucidating the impacts of climate change which emerge gradually on these three key health-related behaviors, particularly focusing on scenarios and projections relevant to people living in the northern Europe.

METHODS

We conducted a systematic literature search in three different databases in January 2023 to identify English language review articles summarizing the effects of climate change on either physical activity, nutrition, sleep, or their combination.

RESULTS

We identified 15 review articles on the topic. Data on climate change impacts on nutrition and sleep were sparse, and those on physical activity were heterogeneous. The climate in northern Europe will become warmer and sunnier in summer as well as warmer and darker in winter, which will probably increase the level of physical activity, but decrease the consumption of fruits and vegetables, as well as increase the occurrence of sleep disturbances in a population.

CONCLUSIONS

The anticipated changes in physical activity, nutrition and sleep driven by climate change influence population health and call for grass-roots action plans for adaptation.

Association between Two Cardiovascular Health Algorithms and Kidney Stones: A Nationwide Cross-sectional Study

Background and objective

There is limited literature on the relationship between cardiovascular health (CVH) and kidney stones. This study aims to compare the association of Life's Simple 7 (LS7) and Life's Essential 8 (LE8) with kidney stone prevalence.

Methods

A cross-sectional analysis was conducted utilizing NHANES data (2007-2018). Participants aged ≥20 yr with a history of kidney stones and available LS7 and LE8 scores were included. Both LS7 and LE8 are scored such that higher scores indicate better CVH. Weighted proportions and multivariable logistic regression models assessed the relationship between CVH metrics and kidney stone prevalence, adjusting for confounders. The receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were determined to distinguish between LS7 and LE8 in terms of their discriminative ability within the model associated with kidney stones.

Key findings and limitations

A total of 23 563 adults were included; the mean age was 48.1 yr (48.1% male). Kidney stone prevalence was 10.1%. The mean LS7 and LE8 scores were 8.4 and 68.6, respectively. A multivariate analysis and the restricted cubic spline model indicated a significant nonlinear negative correlation between these CVH measures and kidney stone prevalence. The LS7 ideal group showed a lower prevalence than the poor group (odds ratio [OR] = 0.53; 95% confidence interval [CI] 0.41-0.69). The high CVH group had a lower prevalence than the low CVH group (OR = 0.46; 95% CI 0.36-0.57). The AUCs for evaluating LS7 and kidney stones, as well as for LE8 and kidney stones were 0.676 and 0.677, respectively. Limitations were as follows: cross-sectional design limiting causal inference, recall bias from self-reported data, and potential residual confounding.

Conclusions and clinical implications

Both CVH algorithms show a significant nonlinear negative correlation with kidney stone prevalence. LS7 may be more accessible for broader implementation. Further high-quality prospective studies are needed to clarify this relationship.

Patient summary

In this study, we explored the connection between heart health and kidney stones using data from a large national survey. We found that better heart health, measured by two different scoring methods, is linked to a lower chance of having kidney stones. Our results suggest that promoting heart health could help reduce the risk of kidney stones in adults.

Digital Health Interventions for the Optimization of Postpartum Cardiovascular Health: A Systematic Scoping Review

Background

Digital health technologies have been proposed as a potential solution to improving maternal cardiovascular (CV) health in the postpartum (PP) period. In this context we performed a systematic scoping review of digital health interventions designed to improve PP CV health.

Methods

We conducted a systematic review of PubMed/MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Library. We included studies of PP women, with an intervention involving digital or mobile health (wearable devices, telemedicine, or remote monitoring). We included studies that measured an outcome related to CV health.

Results

110 full studies were reviewed for eligibility and 38 were included. Studies were categorized into 4 broad CV outcomes: blood pressure (BP), physical activity (PA), diet/weight loss and cardiometabolic markers. Digital health interventions included mobile applications, text-based coaching, interactive websites, virtual reality, wearable devices. The majority of remote BP monitoring programs (N = 5 studies) were successful in optimizing BP. 14 studies examined interventions aimed at improving PA levels of which 6/14 studies showed modest benefit at increasing PA. The majority of interventions aimed at weight loss (N = 27 studies) showed no significant benefit in terms of lowered caloric intake and/or weight loss up to 1 year PP. 6 studies examined improvements in cardiometabolic markers such as lipids and glucose levels, of which the majority showed no benefit.

Conclusion

The majority of studies we reviewed found that digital health interventions such as mobile health, telemonitoring and wearable devices were feasible and had mixed effectiveness in improving postpartum CV health in the postpartum period.

A good night's rest: A contemporary review of sleep and cardiovascular health

Sleep is increasingly recognized as a significant contributor to the development of cardiovascular disease (CVD). Recent American Heart Association guidelines incorporate sleep duration into the "Life's Essential Eight" framework of ideal cardiovascular health. This article will review the evidence relating sleep duration, regularity, and quality with all-cause and cardiovascular mortality, cardiometabolic syndrome, and coronary artery disease in adults. Short sleep duration is strongly associated with cardiovascular mortality, cardiometabolic risk factors, and coronary artery disease. Limited studies also suggest a possible U-shaped association, with long sleep duration also associated with greater cardiovascular risk. Sleep regularity has emerged as a strong and independent risk factor for CVD-related mortality, cardiometabolic syndrome, and subclinical atherosclerosis. Less is known about the impact of sleep quality on CVD, though a number of observational studies suggest a possible association with metabolic syndrome and subclinical atherosclerosis. This review provides an update of the literature on the cardiovascular impact of sleep for the everyday clinician and highlights gaps in knowledge that warrant future research.

Investigating the effect of occupational noise exposure in the risk of atrial fibrillation: a case study among Chinese occupational populations

PURPOSE

This study examines the link between high occupational noise exposure and atrial fibrillation (AF), given the limited existing evidence.

METHODS

We conducted a cross-sectional study among participants from a large heavy industry enterprise in China. High noise exposure was defined as an equivalent A-weighted sound level (LAeq, 8 h) of ≥ 80 dB(A) during an 8 h workday. Statistical analyses included univariate analysis to assess relationships between high noise exposure, cardiovascular risk factors, and AF. Mediation analysis identified potential mediators between high noise exposure and AF. Propensity score matching (PSM) and multivariable analysis were used to evaluate the independent association between high noise exposure and AF.

RESULTS

A total of 4530 participants were included, with 1526 experiencing high noise exposure, and 167 diagnosed with AF. Adjusted mediation analysis revealed that sleep disorders, hypertension, dyslipidemia, and dietary quality were the primary mediators for AF among those exposed to high noise, accounting for 12.4%, 9.6%, 8.9%, and 6.7% of the effect, respectively. PSM analysis showed a significantly higher proportion of AF in individuals with high noise exposure compared to those with low exposure (5.4% vs. 3.0%, P = 0.003). Multivariable analysis indicated that the risk of AF was doubled in individuals with high noise exposure (OR = 1.99, 95% CI 1.38-2.88, P < 0.001).

CONCLUSION

High occupational noise exposure increases the risk of AF in the working population, acting both as an independent risk factor and through mediation effects. Sleep disorders, hypertension, dyslipidemia, and dietary quality are the main mediators. These findings highlight the importance of integrating noise control with cardiovascular health management in workplace safety policies to prevent AF among industrial workers.

Interactions of chronic stress exposure and stress appraisal on vascular endothelial function among young adults

We investigated the associations of ongoing, chronic stress exposure and stress appraisal on vascular endothelial function (VEF) in young adults. In 72 healthy young adults (74% female; age = 25 ± 1 yr), we assessed chronic stress exposure and appraisal with a measure that quantified chronic stress exposure and chronic stress appraisal related to eight specific stressors over the last year. Participants completed the perceived stress scale (PSS) as a measure of global, proximal stress appraisal. VEF was assessed using the brachial artery flow-mediated dilation technique. We examined relations among ongoing, chronic stress exposure and stress appraisal versus VEF adjusted for age and sex, and then assessed whether stress appraisal moderated the effect of chronic stress exposure on VEF. Chronic stress exposure (β = -0.24, P = 0.045), but not chronic stress appraisal (β = 0.07, P = 0.56) or perceived stress (β = -0.20, P = 0.11), was related to VEF. Perceived stress (P = 0.046), but not chronic stress appraisal (P = 0.54), moderated the association between chronic stress exposure and VEF. The effect of chronic stress exposure on VEF ceased to be significant at a PSS score of ∼22. Subsequent exploratory stratified analysis indicated that those with PSS ≥22 had increased exposure to adverse childhood experiences (+1.6 ± 0.6, P = 0.01), greater depressive symptoms (+10.2 ± 2.7, P < 0.001), and reduced psychological resilience (-7.6 ± 3.5, P = 0.036). Chronic stress exposure significantly predicts impaired VEF among young adults. Furthermore, this relation is influenced by proximal perceived stress, such that the association of chronic stress exposure on VEF may be obscured at high levels of proximal perceived stress.NEW & NOTEWORTHY Our findings indicate that ongoing chronic stress exposure over the last year is significantly associated with reduced vascular endothelial function among apparently healthy young adults. Our data provide important insights into the interplay of chronic stress exposure versus proximal perceived stress and may also support the hypothesis that young adults who are sensitized to stress may be particularly vulnerable to stress-related impairments in vascular endothelial function.

Association between Life's Essential 8 and Infertility as Well as the Mediating Effects of Oxidative Stress and Inflammatory Factors Among U.S. Women Aged 18-45 Years

Management of cardiovascular disease in pregnancy is important, yet the association between cardiovascular health and infertility is rarely reported. In this study, we aimed to explore the association between Life's Essential 8 (LE8), a novel cardiovascular health (CVH) measure, and infertility, and to investigate potential mediating mechanisms. This study investigated cross-sectional data from the 2013-2018 National Health and Nutrition Examination Survey. LE8 score (ranging from 0 to 100) was calculated as the unweighted average of eight CVH metrics. The association between LE8 and infertility was explored through weighted multiple logistic regression. Restricted cubic splines were used to explore nonlinear correlation. In addition, mediation analysis was conducted to investigate the role of oxidative stress and inflammatory markers systematically. After strict exclusion criteria, 1703 American women aged 18-45 years were included. After full adjustment, the LE8 score showed a negative correlation with infertility [per 1 SD increase, OR = 0.675, 95% CI: 0.553-0.824], with a linear dose-response relationship (non-linear P = 0.122). Similar linear negative correlations were found between health factor scores and infertility, with higher body mass index and glucose scores having a significantly lower risk of infertility. Stratified analyses showed a stronger inversed relationship between LE8 and infertility in younger populations. Moreover, mediation analysis revealed that uric acid concentration and lymphocyte count mediated the effect of LE8 on infertility (P < 0.05). LE8 and its subscale scores were linearly and negatively associated with infertility, which may be mediated in part through uric acid and lymphocyte count. Focusing on weight management and glycemic control can effectively reduce the risk of infertility.

Comparison of the associations between life's essential 8 and life's simple 7 with stroke: NHANES 1999-2018

OBJECTIVE

This study aims to explore the association between Life's Essential 8 (LE8) and stroke and all-cause mortality, and compare whether it has an advantage over Life's Simple 7 (LS7).

METHODS

This study investigated data from NHANES spanning from 1999 to 2018. The LE8 was categorized as low, moderate and high cardiovascular health (CVH). LS7 score was categorized as inadequate, average, or optimal. Weighted logistic regression and restricted cubic spline (RCS) were used to examin correlations. Receiver operating characteristic (ROC) curves were employed to detect the accuracy in predicting stroke. The stratified and sensitivity analyses were conducted along with mediation analysis. In addition, a longitudinal cohort was constructed by combining the mortality data, and Cox regression models were utilized to determine the association between CVH and the mortality rate.

RESULTS

For LE8, compared to low CVH, moderate CVH was associated with a 41 % lower risk of stroke, and high CVH was associated with a 71 % lower prevalence of stroke. For LS7, compared to inadequate CVH, average CVH was associated with a 24 % lower prevalence of stroke, and optimal CVH was associated with a 39 % lower prevalence of stroke. RCS showed inverse dose-response relationships of both LE8 and LS7 with stroke. In unweighted ROC, LE8 (AUC = 0.702, 95 % CI: 0.685-0.718, P < 0.001) has a stronger ability to discriminate stroke than LS7 (0.677, 95 % CI: 0.658-0.696, P < 0.001) (PDeLong = 0.046). Sensitivity analyses demonstrated robustness of LE8 in predicting stroke. GGT and WBC mediated 4.92 % and 4.58 % of the association, respectively. Cox regression showed neither LE8 nor LS7 were predictive of mortality risk among stroke survivor.

CONCLUSIONS

LE8 outperformed LS7 in classifying stroke. Oxidative stress and inflammation mediated the association between LE8 and stroke.

A digital tool for self-reporting cardiovascular risk factors: The RADICAL study

Aims

Cardiovascular diseases remain the leading cause of death worldwide. Risk stratification and early interventions are essential to overcome this reality. The RADICAL Study ( R isk A ssessment via D igital I nput for C ardiovascular A nd L ifestyle Factors) aimed to evaluate the prevalence of self-reported cardiovascular risk factors in individuals without known cardiovascular disease using a digital tool.

Methods and results

A digital self-reported cardiovascular risk stratification tool, comprising 23 questions about classical and lifestyle cardiovascular risk factors, was completed by 4149 individuals aged 40-69 years (median age 53.0 [47.0; 60.0] years; 78 % women). Among the cardiovascular risk factors, 40.9 % reported hypercholesterolemia, 26.8 % hypertension, 17.3 % smoking, 5.8 % diabetes, 58.4 % physical inactivity, 19.4 % obesity, 33.7 % sleep less than 7 h/night, and 12.1 % had composite dietary risk factors. Most of the participants (89.9 %) referred having at least one of the eight cardiovascular risk factors. Women had 27 % higher odds of having at least one cardiovascular risk factor compared to men (OR = 1.27, 95 % CI [1.00, 1.60]). Participants aged 50-59 years also had higher odds of having at least one CV risk factor compared to those aged 40-49 years (OR = 1.35, 95 % CI [1.07, 1.70]).

Conclusion

The RADICAL Study reveals a high prevalence of cardiovascular risk factors in adults without known cardiovascular disease. Beyond the relevance of traditional risk factors, such as hypercholesterolemia and hypertension, the results regarding physical activity, dietary and sleeping habits are concerning. A self-reported cardiovascular risk identification digital tool could be feasible and help to improve cardiovascular prevention.

Frontiers in subclinical atherosclerosis and the latest in early life preventive cardiology

ABSTRACT

Subclinical atherosclerosis underlies most cardiovascular diseases, manifesting before clinical symptoms and representing a key focus for early prevention strategies. Recent advancements highlight the importance of early detection and management of subclinical atherosclerosis. This review underscores that traditional risk factor levels considered safe, such as low-density lipoprotein cholesterol (LDL-C) and glycated haemoglobin (HbA1c), may still permit the development of atherosclerosis, suggesting a need for stricter thresholds. Early-life interventions are crucial, leveraging the brain's neuroplasticity to establish lifelong healthy habits. Preventive strategies should include more aggressive management of LDL-C and HbA1c from youth and persist into old age, supported by public health policies that promote healthy environments. Emphasising early education on cardiovascular health can fundamentally shift the trajectory of cardiovascular disease prevention and optimise long-term health outcomes.

Are Your Kidneys Ok? Detect Early to Protect Kidney Health

Early identification of kidney disease can protect kidney health, prevent kidney disease progression and related complications, reduce cardiovascular disease risk, and decrease mortality. We must ask "Are your kidneys ok?" using serum creatinine to estimate kidney function and urine albumin to assess for kidney and endothelial damage. Evaluation for causes and risk factors for chronic kidney disease (CKD) includes testing for diabetes and measurement of blood pressure and body mass index. This World Kidney Day we assert that case-finding in high-risk populations, or even population level screening, can decrease the burden of kidney disease globally. Early-stage CKD is asymptomatic and simple to test for, and recent paradigm shifting CKD treatments such as sodium glucose co-transporter-2 inhibitors dramatically improve outcomes and favor the cost-benefit analysis for screening or case-finding programs. Despite this, numerous barriers exist, including resource allocation, health care funding, health care infrastructure, and health care professional and population awareness of kidney disease. Coordinated efforts by major kidney nongovernmental organizations to prioritize the kidney health agenda for governments and aligning early detection efforts with other current programs will maximize efficiencies.

Self-Management Interventions for Black Women at Risk for Cardiovascular Disease: A Systematic Literature Review

Cardiovascular disease (CVD) is the leading cause of death among Black women. When compared with their non-Hispanic White counterparts, Black women are about 50% more likely to have uncontrolled high blood pressure (BP). The disproportionate burden of CVD in Black women highlights the need for CVD prevention programs in this population. The present systematic literature review examined the updated literature on the efficacy of primary prevention self-management interventions for Black women with CVD risk factors. Searches were run on PubMed, Cochrane, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases based on the following inclusion criteria: papers published from September 22, 2018; English language; U.S. studies only; original research reports; prospective clinical trials; cardiovascular health promotion/self-management interventions that target at least two health practices for primary prevention; comorbid conditions without a cardiovascular event; at least one patient-level outcome; and Black women at least 18 years of age. Twelve papers met the inclusion criteria. Health practices targeted included physical activity, nutrition, weight loss, health knowledge, and BP control. Nine of the 12 papers reported statistically significant improvements on at least one CVD risk factor including weight loss, physical activity, BP control, waist circumference, and depression. Culturally tailored self-management interventions appear to be feasible with weak to moderately high evidence of efficacy for reducing CVD risk factors in Black women. Further research should focus on the influence that social determinants of health, including mental health, may have on self-management and CVD risk in this population.

Cardiovascular health and risks of atrial fibrillation and its prognosis

Background

Atrial fibrillation (AF) is the most common cardiac arrhythmia around the world with an increased risk of a broad spectrum of adverse comorbidities and death. Whether cardiovascular health (CVH) is associated with AF development remains unclear.

Methods

238,420 participants without cardiovascular disease at baseline were selected from the UK Biobank study cohort from 2006 to 2010. CVH was defined based on "Life's Essential 8″ scores. Sex-specific multi-state Markov and flexible parametric survival models were used to estimate the hazard ratio (HR) and 95 % confidence intervals (95 % CI) for the associations of CVH with incident AF and its prognosis.

Results

In fully-adjusted models, CVH is significantly associated with a reduced risk of incident AF among both men and women, after accounting for the potential impact of death. Among AF patients without other evaluated diseases, a higher CVH score was generally linked with a reduced risk of death in both sexes. Among AF patients with incident prognostic diseases, only CVH associated with death following heart failure (0.78, 0.63-0.97) was observed among men, whereas CVH was significantly associated with death following coronary heart disease (0.80, 0.69-0.93), stroke (0.73, 0.61-0.89) and dementia (0.79, 0.71-1.03) among women.

Conclusions

We found significant associations between CVH and the risk reduction of incident AF and its prognostic outcomes, with these associations being more pronounced among women. Findings suggest a potential of screening CVH for both primary prevention of new-onset AF and the secondary prevention to improve AF prognosis.

Core Components of Cardiac Rehabilitation Programs: 2024 Update: A Scientific Statement From the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation: Endorsed by the American College of Cardiology

The science of cardiac rehabilitation and the secondary prevention of cardiovascular disease has progressed substantially since the most recent American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation update on the core components of cardiac rehabilitation and secondary prevention programs was published in 2007. In addition, the advent of new care models, including virtual and remote delivery of cardiac rehabilitation services, has expanded the ways that cardiac rehabilitation programs can reach patients. In this scientific statement, we update the scientific basis of the core components of patient assessment, nutritional counseling, weight management and body composition, cardiovascular disease and risk factor management, psychosocial management, aerobic exercise training, strength training, and physical activity counseling. In addition, in recognition that high-quality cardiac rehabilitation programs regularly monitor their processes and outcomes and engage in an ongoing process of quality improvement, we introduce a new core component of program quality. High-quality program performance will be essential to improve widely documented low enrollment and adherence rates and reduce health disparities in cardiac rehabilitation access.

Social Determinants of Health in the Development of Cardiovascular-kidney-metabolic Syndrome

Cardiovascular-kidney-metabolic (CKM) syndrome is characterized by the interactions among the metabolic risk factors, chronic kidney diseases (CKD) and cardiovascular diseases (CVD). Social determinants of health (SDOH) include society, economy, environment, community and psychological factors, which correspond with cardiovascular and kidney events of the CKM population. SDOH are integral components throughout the entire spectrum of CKM, acting as key contributors from initial preventative measures to ongoing management, as well as in the formulation of health policies and the conduct of research, serving as vital instruments in the pursuit of health equity and the improvement of health standards. This article summarizes the important role of SDOH in CKM syndrome and explores the prospects of comprehensive management based on SDOH. It is hoped that these insights will offer valuable contributions to improving CKM-related issues and enhancing health standards.

Sleep: The silent hero in cardiometabolic health

The essential role of sleep in overall health is increasingly recognized, yet it remains underemphasized in both clinical and public health contexts. Despite extensive research linking poor sleep health to chronic conditions such as cardiovascular disease, type 2 diabetes, and cognitive decline, sleep health is not routinely assessed or integrated into standard care practices. Sleep problems, including insomnia, sleep apnea, and poor sleep quality, are prevalent globally, affecting over 30 % of the population and contributing to significant public health burdens like cardiometabolic disease, mental health disorders and multimorbidity. The economic implications are substantial, with insufficient sleep imposing significant societal and financial costs worldwide. Recognizing this, recent initiatives like the American Heart Association's inclusion of sleep in the Life's Essential 8 framework highlight the importance of sleep in cardiometabolic health. Integrating sleep into clinical and public health strategies is crucial, due to the wide-ranging impact of sleep on cardiometabolic health. Social, environmental, and demographic factors also play significant roles in sleep health, with lower socioeconomic groups and women often experiencing poorer sleep, further exacerbating health disparities. Adopting a life course approach and promoting healthy sleep behaviors early in life are essential for mitigating long-term cardiometabolic risks. Effective evidence-based strategies for improving sleep behaviors and cardiometabolic health, beyond addressing sleep disorders, include prioritizing sleep hygiene, managing stress, promoting physical activity, maintaining a healthy diet, and reducing substance use, all of which contribute to overall well-being. In conclusion, incorporating sleep health into routine cardiometabolic risk stratification, prevention, and management is essential for improving overall health outcomes.

Atrial fibrillation in Black American patients: A review of genetics, risk factors, and outcomes

Atrial fibrillation (AF), the most common arrhythmia in the United States, affects 6 million Americans, with numbers projected to increase to 12 million by 2030. A racial paradox difference in the incidence and prevalence of AF exists between Black and White Americans. Black Americans are less prone than White Americans to development of AF, but they display a higher burden of modifiable risk factors for cardiovascular disease and higher rates of ischemic stroke. Data pertaining to the American Heart Association Life's Simple 7 (LS7) health metrics show that Black Americans have suboptimal LS7 scores compared with White Americans on average despite lower genetic predisposition to AF. This trend suggests the impact of cardiovascular health on the development and progression of AF. Social, genetic, and lifestyle risk factors have been shown to play a role in the racial paradox and AF outcomes in Black Americans. This review summarizes factors contributing to the racial paradox and discusses suggestions for improved health outcomes in Black Americans with AF.

Multimodal Treatment of Sleep Apnea

Obstructive sleep apnea (OSA) is a common condition linked with multiple comorbidities. Continuous positive airway pressure (CPAP) devices, though the gold standard for OSA treatment, often do not address the entirety of the disorder. Various treatment strategies exist to address OSA beyond CPAP, each targeting different OSA aspects. These include managing comorbid sleep disorders, anatomic considerations, endotype-directed therapy, and lifestyle interventions. These comprehensive approaches aim to improve the benefits of treatment, and reduce the complications associated with OSA.

Cardiovascular and Risk Factor Outcomes for Ethnic Minorities From Cardiac Rehabilitation: A Systematic Review and Meta-Analysis

PURPOSE

To determine the benefits of cardiac rehabilitation (CR) among ethnic minorities for cardiovascular risk factors (systolic blood pressure [BP], exercise capacity, lipids, body fat), mortality, and morbidity, and compare outcomes to majority reference groups.

REVIEW METHODS

We searched electronic databases (Medline, EMBASE, CINAHL, Scopus, Cochrane Library) from inception until September 2023 for studies reporting CR outcomes of ethnic minorities. Meta-analyses were conducted for data that could be pooled using random effects model. Data that were not suitable for meta-analysis were synthesized and reported narratively.

SUMMARY

Thirteen studies with a total of 132 109 participants (10 494 from ethnic minorities [8% of total participants]) were included. Patients from ethnic minority groups made improvements in several outcomes post-CR. These outcomes were equivalent to majority groups for systolic BP (Mean Difference [MD] = -0.69: 95% CI, -1.62 to 0.24 mmHg), maximal exercise capacity (MD = -0.10: 95% CI, -0.63 to 0.44 metabolic equivalents of task), total cholesterol (MD = 0.16: 95% CI, -0.01 to 0.33 mmol/L), and low-density lipoprotein cholesterol (MD = 0.25: 95% CI, -0.04 to 0.54 mmol/L). However, ethnic minorities achieved less improvements than the majority for body mass index (MD = -0.31: 95% CI, -0.47 to -0.14 kg/m2) and waist circumference (MD = -1.50: 95% CI, -2.33 to -0.68 cm). Narrative synthesis indicated equivalent outcomes for minorities for all-cause mortality and mean cholesterol, with worse risk of hospitalization at 1 year. Patients from ethnic minorities attending CR achieve equivalent benefits to majority counterparts for multiple risk factors and potentially mortality and morbidity, therefore CR should be strongly promoted. Individual tailoring may be needed to address adiposity and exercise capacity.
