Abstract

BACKGROUND: Better cardiovascular health is associated with lower cardiovascular disease risk.METHODS AND RESULTS: We determined the association between cardiovascular health and healthcare utilization and expenditures in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. We included 6262 participants ≥65 years with Medicare fee-for-service coverage for the year after their baseline study visit in 2003-2007. Cardiovascular health at baseline was assessed using the American Heart Association's Life's Simple 7 (LS7) metric, which includes 7 factors: cigarette smoking, physical activity, diet, body mass index, blood pressure, cholesterol, and glucose. Healthcare utilization and expenditures were ascertained using Medicare claims in the year following baseline. Overall, 17.2%, 31.1%, 29.0%, 16.4% and 6.4% of participants had 0 to 1, 2, 3, 4, and 5 to 7 ideal LS7 factors, respectively. The multivariable-adjusted relative risk (95% confidence interval [CI]) for having any inpatient and outpatient encounters comparing participants with 5 to 7 versus 0 to 1 ideal LS7 factors were 0.55 (0.39, 0.76) and 1.00 (0.98, 1.02), respectively. Among participants with 0 to 1 and 5 to 7 ideal LS7 factors, mean inpatient expenditures were $3995 and $1250, respectively, mean outpatient expenditures were $5166 and $2853, respectively, and mean total expenditures were $9147 and $4111, respectively. After multivariable adjustment, the mean (95% CI) cost difference comparing participants with 5 to 7 versus 0 to 1 ideal LS7 factors was -$2551 (-$3667, -$1435) for inpatient, -$2410 (-$3089, -$1731) for outpatient, and -$5016 (-$6577, -$3454) for total expenditures.CONCLUSIONS: Better cardiovascular health is associated with lower risk for inpatient encounters and lower inpatient and outpatient healthcare expenditures.
