Abstract:

BACKGROUND: Veterans are at an increased cardiovascular risk compared to age- and sex-matched non-Veterans. Cardiac rehabilitation (CR) can improve outcomes in cardiovascular disease, but its use in men and women Veterans is not well understood. OBJECTIVES: This study aimed to examine CR participation by sex and socioeconomic status among Veterans. METHODS: The authors conducted a retrospective cohort study from January 1, 2021, to December 31, 2023, using a national electronic health record database. The primary outcome was participation in at least 1 CR session among patients within 1 year of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass surgery. Multivariable logistic regression models accounted for patient-level (demographics, medical/psychiatric comorbidities) and community-level factors. Area deprivation indices (ADIs) (analyzed as quartiles) assessed socioeconomic status. RESULTS: Among 82,496 CR-eligible Veterans (3.6% women), CR participation was low (10.4%) and similar by sex (women = 10.2%, men = 10.4%). Women Veterans did not differ significantly in CR participation compared to men Veterans after adjusting for patient-level and community-level characteristics, including age, race, cardiac and comorbidities, mental health risk factors, rural-urban status, and ADI (adjusted OR: 0.90; 95% CI: 0.79-1.03; P = 0.121). Veterans in the most deprived ADI quartile were less likely to participate vs the least deprived quartile (adjusted OR: 0.82; 95% CI: 0.75-0.89; P < 0.001). CONCLUSIONS: CR participation among U.S. Veterans remains low, far below that of the Medicare population (10.4% vs 28%), with no significant differences in initiation by sex. However, low socioeconomic status is associated with decreased uptake. Further research is needed to explore innovative, Veteran-specific CR delivery models.
