Cardiac rehabilitation and spousal support linked to activity levels in heart disease patients
A systematic review of 24 observational studies examined what factors shape physical activity, sedentary time, and sleep in coronary heart disease patients. Participation in cardiac rehabilitation, younger age, spousal support, and residential environment showed the strongest associations with higher activity levels.
Researchers systematically reviewed 24 observational studies to identify which factors—across individual, social, environmental, and policy levels—influence how coronary heart disease patients distribute their 24-hour time between physical activity, sedentary behavior, and sleep. Most studies (17 of 24) focused on single behaviors in isolation; only seven examined two activity behaviors simultaneously, suggesting no prior study had comprehensively assessed all three movement dimensions together in this population.
Using the socioecological model as a framework, the review organized explanatory variables into four hierarchical levels. Intrapersonal factors dominated the evidence: aging was significantly associated with reduced physical activity, while participation in cardiac rehabilitation programs showed the most consistent link to increased activity. At the interpersonal level, spousal support and social support moderated both activity levels and sedentary time. Environmental factors—particularly residential characteristics and proximity to exercise facilities—were associated with 24-hour movement patterns. Policy-level variables, however, showed no significant associations across the included studies. The authors concluded that intrapersonal factors (especially cardiac rehabilitation participation) combined with interpersonal support and an optimized residential or facility-based exercise environment represent the most actionable intervention points for behavioral change in heart disease patients.
Among the 24 studies analyzed, only seven explored multiple behaviors simultaneously—a major limitation suggesting the field lacks integrated data on how these three domains interact within individuals. The intrapersonal level dominated findings, but this does not mean individual physiology determines everything; rather, it reflects which factors researchers have measured most thoroughly. Cardiac rehabilitation showed the most consistent association across studies, offering a concrete intervention anchor. Spousal support moderated both physical activity and sedentary behavior in a dose-response manner within some studies, hinting at a genuine social mechanism rather than mere correlation. Environmental determinants (neighborhood walkability, facility proximity, green space) appeared in fewer studies but showed meaningful associations when measured. Notably, the absence of policy-level associations does not imply policy is irrelevant—it reflects that the included observational studies rarely captured policy variables such as healthcare reimbursement, public transportation funding, or workplace mandates. The heterogeneity across studies (different accelerometers, thresholds, and outcome definitions) limits confidence in precise effect sizes, though directional trends were clear.
