Abstract 18027: Contribution of Sex and Age Differences to Life's Simple 7 Metrics in Cardiac Rehabilitation

Abstract

Background: Life's Simple 7 (LS7) have been identified as key health factors aimed at achieving ideal cardiovascular health (CVH) and improving healthy life expectancy; however, it is unclear if different patient populations respond similarly to optimization of health behaviors. We sought to quantify the contribution of sex and age differences to changes in LS7 components in patients participating in cardiac rehabilitation. Methods: We included 937 adult patients who participated in CR from January 2018 to September 2020. LS7 metrics at baseline (pre-CR) and completion of CR (post-CR) were collected and changes in LS7 components (body mass index (BMI), diet, smoking, physical activity (PA), blood pressure (PB), cholesterol, glucose) were assessed by sex and age groups (<65 vs ≥65 years old). Each LS7 component was assigned 0 (poor), 1 (intermediate), or 2 (ideal) points and a final score was computed to estimate an individual’s level of CVH (0-14 pts): 0-6 = poor, 7-8= intermediate, 9 -14= ideal. Results: The mean age was 64±13 years, and 34% were female. Patients attended a mean of 11.1±12.5 CR sessions. LS7 components with the highest proportion within the poor category were HbA1c (41%) and BMI (50%) at the time of CR enrollment; neither women nor men showed improvement on either component. The trend towards improvement from poor to intermediate range on cholesterol and BP metrics was seen only in older patients (Table 1). Mean LS7 score improvement was greater in the older group, P=.01 (Fig 1). Both women and men equally improved LS7 scores (Table 2, Fig 2). Conclusions: Patients participating in CR demonstrated improvement in overall LS7 scores regardless of sex and age. However, age disparities exist in LS7 metrics, with exacerbated differences noted by a lack of improvement in LS7 components such as BP and cholesterol in younger patients. Our insights provide opportunities to explore equitable CVH.
