Association between Life's Essential 8 score and risk of premature mortality in people with and without type 2 diabetes: A prospective cohort study

Association of Life's essential 8 score with the risk of all-cause mortality and cardio-cerebrovascular mortality in patients with stroke

BACKGROUND

A higher Life's Essential 8 (LE8)-based cardiovascular health (CVH) has been reported to be associated with a lower risk of both all-cause mortality and cardio-cerebrovascular diseases (CCVDs) related mortality in adults in the United States. At the same time, multiple studies have shown a significant negative association of CVH with the risk of stroke and CCVDs. Since no research has investigated the applicability of the LE8 in stroke patients, this study aimed to explore the association of LE8 with all-cause mortality and cardio-cerebrovascular mortality in stroke patients.

METHODS

Data of patients were extracted from the National Health and Nutrition Examination Surveys (NHANES) database in 2007-2018 in this retrospective cohort study. Weighted univariate and multivariate COX regression analyses were utilized to investigate the associations of LE8 with all-cause mortality and cardio-cerebrovascular mortality. We further explored these relationships in subgroups of age, gender, body mass index (BMI), cancer, congestive heart failure (CHF), and coronary heart disease (CHD). The evaluation indexes were hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Among the eligible patients, 278 died from all-cause and 89 (8.38%) of them died due to CCVDs. After adjusting for covariates, patients with LE8 score ≥ 58.75 seemed to have both lower risk of all-cause mortality (HR = 0.46, 95%CI: 0.31-0.69) and cardio-cerebrovascular mortality (HR = 0.51, 95%CI: 0.26-0.98), comparing to those with LE8 score < 48.123. Higher LE8 scores were associated with lower risk of all-cause mortality in patients aged < 65 years old, without cancer, and whatever the gender, BMI, CHF or CHD conditions (all P < 0.05). The relationships between high LE8 scores and low cardio-cerebrovascular mortality risk were only found in age < 65 years old and non-cancer subgroups (all P < 0.05).

CONCLUSION

A higher LE8 score was associated with lower risk of both all-cause mortality and cardio-cerebrovascular mortality in patients with stroke, which may provide some reference for risk management and prognosis improvement in stoke. However, more evidences are needed to verify this beneficial role of high LE8 score in stroke prognosis.

Life's Essential 8 and risks of cardiovascular morbidity and mortality among individuals with type 2 diabetes: A cohort study

BACKGROUND

The association of cardiovascular health levels, as measured by the Life's Essential 8 score, with cardiovascular disease (CVD) incidence and mortality among individuals with type 2 diabetes (T2D) has not been fully elucidated.

METHODS

This cohort study included 15,118 participants with T2D from the UK Biobank who were free of CVD and cancer at baseline. The cardiovascular health of participants was evaluated using the Life's Essential 8 score, categorizing their health levels into low, moderate, and high based on this assessment.

RESULTS

During a median follow-up period of 13.0 years, we observed a total of 4421 cases of CVD, comprising 3467 cases of coronary heart disease (CHD), 811 cases of stroke, 1465 cases of heart failure (HF), and 523 cases of CVD mortality. Compared to participants with low cardiovascular health, those with high cardiovascular health had a 52 %, 50 %, 47 %, 67 %, and 51 % lower risk of CVD, CHD, stroke, HF, and CVD mortality, respectively. Among the components of the Life's Essential 8 score, body mass index showed the highest population attributable risk of 12.1 %. Similar findings were observed in joint analyses of cardiovascular health and diabetes severity status.

CONCLUSIONS

This study emphasizes the importance of maintaining good cardiovascular health among individuals with T2D to reduce their risk of CVD incidence and mortality.

Association of change in cardiovascular health based on life's essential 8 with incident cardiovascular disease

Objective

To evaluate whether and to what extent changes in cardiovascular health (CVH) based on life's essential 8 (LE8) are associated with incident cardiovascular disease (CVD).

Methods

A total of 7,194 participants were derived from UK Biobank. CVH was evaluated using a modified version of LE8. Participants were classified into three groups according to their LE8 score: high CVH (LE8 score≥80), moderate CVH (50≤LE8 score<80), and low CVH (LE8 score<50). Changes in CVH between 2006/2010 and 2012/2013 were analyzed.

Results

During a median of 10.3 years of follow-up, CVD was observed in 597 participants. Compared to the consistent moderate group, the moderate to low group was associated with about 128 % increased risk of CVD (Hazard ratio [HR]: 2.28; 95 % confidence interval [CI]: 1.61, 3.23), and the relevant HR (95 % CI) was 2.19 (1.46, 3.29) for the consistent low group; no statistically significant results were observed in the other groups. Moreover, no statistically significant exposure-response association between absolute change in LE8 score and incident CVD was documented (Poverall=0.15).

Conclusion

Change in CVH based on LE8 was associated with the risk of CVD; however, the relationship varied widely in different CVH change patterns.

Life's Essential 8 and heart failure among patients with chronic kidney disease: the Kailuan Cohort Study

AIMS

Patients with chronic kidney disease (CKD) are at an increased risk of developing heart failure. The American Heart Association recently released a new metric, Life's Essential 8 (LE8), for health promotion. However, evidence regarding associations between LE8 and heart failure risk among patients with CKD is scarce.

METHODS AND RESULTS

A total of 16 190 patients with CKD (mean age 55.9 years), free of cardiovascular disease at recruitment from the Kailuan Study, were included. Cardiovascular health was assessed using the LE8 score. Incident heart failure events were ascertained via linkage of electronic health record data. Cox proportional hazards regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs). There were 814 (5.0%) patients in the high LE8 criteria, with 13 180 (81.4%) in the moderate, and 2196 (13.6%) in the low LE8 category, respectively. During a median follow-up of 13.7 years, 724 incident heart failure cases were documented. Compared with the low LE8 category, the HRs (95% CIs) for heart failure were 0.58 (0.48, 0.71) for the moderate LE8 category and 0.32 (0.19, 0.54) for the high LE8 category (P for trend <0.001). In addition, the association was stronger in patients aged ≤65 years compared with their older counterparts (P for interaction = 0.01).

CONCLUSION

Our data showed a strong graded inverse association between the LE8-defined cardiovascular health and the risk of heart failure among patients with CKD. Our findings support the importance of adopting the LE8 among patients with CKD to prevent heart failure.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Associations Between Life's Essential 8 and Abdominal Aortic Calcification Among Middle-Aged and Elderly Populations

BACKGROUND

Abdominal aortic calcification (AAC) is an independent risk factor for cardiovascular disease. We aim to examine the associations between Life's Essential 8 (LE8), the recently updated measurement of cardiovascular health (CVH), and AAC among participants aged ≥40 years.

METHODS AND RESULTS

This population-based cross-sectional study used data from the National Health and Nutrition Examination Survey in 2013 to 2014. AAC (AAC score>0) and severe AAC (AAC score>6) were quantified by the Kauppila score system. Multiple linear, multivariable logistic, and restricted cubic spline models were used to assess the associations. A total of 2369 participants were included with a mean AAC score of 1.41 (0.13). Participants in the high-cardiovascular-health group had lower AAC scores, lower prevalence of AAC, and lower prevalence of severe AAC. After the adjustment of potential confounders (age, sex, race and ethnicity, education levels, marital status, poverty income ratio, estimated glomerular filtration rate, serum creatinine, serum uric acid, serum phosphorus, and serum total calcium), higher cardiovascular health was significantly associated with lower risk of AAC. Meanwhile, elevated nicotine exposure score, blood glucose score, and blood pressure score within the LE8 components were significantly associated with lower risk of AAC. Also, nonlinear dose-response relationships were observed. Subgroup analyses (age strata, sex, poverty income ratio, education levels, marital status) indicated the inverse associations of LE8 and AAC were generally similar in different populations.

CONCLUSIONS

LE8 was negatively and nonlinearly related to the risk of AAC among middle-aged and older populations. Meanwhile, LE8 components should prioritize higher scores for nicotine exposure, blood glucose, and blood pressure evaluations.

Associations of cardiovascular health assessed by life's essential 8 with diabetic retinopathy and mortality in type 2 diabetes

BACKGROUND

Vascular complications are the leading causes of reduced life quality and mortality in type 2 diabetes mellitus (T2DM). Life's Essential 8 (LE8) is a newly modified measurement of cardiovascular health (CVH) by American Heart Association (AHA). Promoting CVH has been previously shown to improve the prognosis of T2DM. However, studies regarding the effects of CVH by LE8 on diabetic retinopathy (DR), a major microvascular complication, and death from the cardiovascular and overall causes in T2DM are currently lacking. This study aimed to investigate these associations thus providing preliminary evidence.

METHODS

A total of 3192 participants from the National Health and Nutrition Examination Survey (NHANES) were included in the final analysis. Records of mortality during follow-up were obtained by linking to the National Death Index. The multivariable logistic regression and Cox proportional hazard regression with restricted cubic splines were used to estimate the associations. Subgroup analyses were performed to examine the effects of gender, age, and duration of T2DM.

RESULTS

648 individuals had DR at baseline. During a median follow-up of 76 months, 645 overall deaths (incidence per 1000 person-years, 26.53%; 95% confidence interval (CI), 26.50-26.56) were ascertained, including 216 from cardiovascular causes (incidence per 1000 person-years, 8.96%; 95% CI, 8.94-8.98). The multivariable-adjusted odds ratio (OR) per 100-point increase of LE8 was 0.80 (95% CI, 0.71-0.90) for DR, and participants with high levels of LE8 were associated with 47% risk reduction (OR, 0.53; 95% CI, 0.40-0.70). The multivariable-adjusted hazard ratio (HR) per 100-point increase of LE8 was 0.71 (95% CI, 0.62-0.81) and 0.68 (95% CI, 0.58-0.85) for all-cause mortality and cardiovascular mortality, respectively. Similar patterns of inverse associations were observed in participants with moderate and high levels of LE8 for all-cause and cardiovascular mortality. Notably, stronger associations between LE8 and mortality were discovered in participants below 60 years (P < 0.05 for interaction). Moreover, LE8 was correlated with all-cause mortality in a linear way (P for nonlinear=0.32).

CONCLUSION

The AHA's newly prompted LE8 was strongly and inversely associated with the risk of DR, all-cause mortality, and cardiovascular-specific mortality in T2DM. LE8 may be a feasible and effective approach in the tertiary prevention of T2DM.
