Mindfulness-based Stress Reduction Combined With Aerobic Training in Cardiac Rehabilitation After Percutaneous Coronary Intervention: A Dual Impact on Kinesiophobia and Heart Rate Variability

Mindfulness-based Stress Reduction Combined With Aerobic Training in Cardiac Rehabilitation After Percutaneous Coronary Intervention: A Dual Impact on Kinesiophobia and Heart Rate Variability

To evaluate the effectiveness of mindfulness-based stress reduction (MBSR) combined with aerobic training on treatment adherence, kinesiophobia, heart rate variability (HRV), exercise tolerance, and psychological stress response in patients with coronary heart disease (CHD) post-percutaneous coronary intervention (PCI).

Post-PCI patients (n = 150) were randomly assigned to an observation group (receiving combined MBSR and aerobic training) and a control group (receiving aerobic training only). Treatment adherence, the Tampa Scale for Kinesiophobia-Heart (TSK-SV Heart), HRV parameters, exercise tolerance, and psychological stress responses were assessed before and after the intervention. Psychological assessments included the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS).

Inclusion Criteria:

• Confirmed diagnosis of coronary heart disease (CHD)

Successful percutaneous coronary intervention (PCI) procedure

No contraindications to rehabilitation exercise

Provision of written informed consent by the patient and their legal guardian

Exclusion Criteria:

• Coexisting severe organic disease (e.g., severe valvular disease, advanced kidney or liver failure)

Malignancy (active or history of cancer within recent years)

Cognitive impairment (sufficient to preclude understanding or compliance with mindfulness-based stress reduction or exercise instructions)
