A quasi-experimental study on couple-based exercise program improving cardiac rehabilitation exercise compliance in post-PCI patients

Background: Percutaneous coronary intervention (PCI) helps treat coronary artery disease but only provides short-term relief and doesn't stop disease progression. Exercise rehabilitation can improve outcomes for patients after PCI and lower the risk of death and new heart problems, but many patients struggle to stick with their exercise routines. Spouses play a crucial role in supporting patients and helping them stay committed to their rehabilitation. This study aims to evaluate the effectiveness of a couple-based exercise program in improving exercise adherence among post-PCI patients.

Methods: This study used a quasi-experimental design, 70 dyads were recruited for a 12-week investigation. Participants were divided into an intervention group to receive the Couple-Based exercise program and a control ensemble for conventional exercise-based cardiac rehabilitation. The primary parameter under examination was exercise adherence. Secondary endpoints encompass exercise self-efficacy, the 6-minute walk test, the 9-item Patient Health Questionnaire, and the Generalized Anxiety Disorder Scale. Data were harvested at baseline and post-intervention (12 weeks).

Result: Following a three-month monitoring period, noticeable differences were observed in the Couples exercise group compared to the control group in the realms of exercise adherence, exercise self-efficacy, the 6-minute walk test, and anxiety-depression indices (P < 0.05).

Conclusion: A couple-based exercise program developed based on a developmental-contextual framework improves exercise adherence and exercise self-efficacy, enhances cardiac function and exercise capacity, and improves anxiety and depression in post-coronary arteriography patients. This approach is likely to be an effective way to improve rehabilitation outcomes, leading to the broader goal of improving patient prognosis and reducing adverse cardiovascular events.

Trial registration: The study's registration was recorded with the Chinese Clinical Trials Registry (12/04/2022, registration number ChiCTR2200058600).
