Abstract 16491: The Relationship Between Cardiovascular Health and 10-year Atherosclerotic Cardiovascular Risk in American Adults

Introduction: Life’s Essential 8 (LE8) is a metric of overall cardiovascular health (CVH) while 10-year atherosclerotic cardiovascular disease (ASCVD) risk is routinely used to guide primary prevention. Yet, the relationship between LE8 and 10-year ASCVD risk is unclear. Hypothesis: CVH has an inverse relationship with 10-year ASCVD risk in adults aged 40–75 years from the National Health and Nutrition Examination Survey 2017-2020 cycle. Methods: Adults with ASCVD and data missing to calculate 10-year ASCVD risk and LE8 scores were excluded. LE8 score was estimated from the mean of LE8 components (scored 0 to 100), with scores ≥80, 79–50, and <49 grouped into ideal, intermediate, and poor CVH, respectively. 10-year ASCVD risk was estimated using pooled cohort equation, with scores <5%, 5–19.9%, and ≥20% grouped as low, borderline/intermediate, and high risk, respectively. The survey weighted chi-square and ANOVA analysis was performed. Results: We included 1,550 adults representing nearly 45 million US adults with a mean age of 57.8 years, 35.3% women. Overall, 35.4%, 42.3%, and 22.3% had low, borderline/intermediate, and high 10-year ASCVD risk, respectively. Low, borderline/intermediate, and high-risk individuals had a mean LE8 score of 68.2, 61.8, and 62.6 (p-value: <0.001) while 18.1%, 7.4%, and 5.6% (p-value: 0.002) had ideal CVH, respectively. Diet, nicotine exposure, body mass index (BMI), and blood lipids metrics were very low across the risk groups (figure). Additionally, the mean blood pressure metric was 41.3 among high-risk and 61.1 among intermediate/borderline-risk individuals. Conclusions: The prevalence of ideal CVH is very low across all 10-year ASCVD risk groups primarily due to poor diet, nicotine exposure, high BMI, and high blood lipids. Since ASCVD risk is predominantly age-dependent and given comparable LE8 scores among borderline/intermediate and high-risk individuals, LE8 may denote an age-independent long-term/lifetime risk.
