Abstract

Background: Comorbid depression and/or anxiety symptoms occur in 25% of patients attending cardiac rehabilitation (CR) programs and are associated with poorer prognosis. There is a need to evaluate psychological interventions, including meditation, that have potential to improve psychological health in CR programs.

Aims: The aim of this study was to determine the feasibility and acceptability of integrating a meditation intervention into an existing Australian CR program for the reduction of depression and anxiety symptoms.

Methods: This was a mixed-methods feasibility randomized controlled trial. Thirty-one patients with CVD and, at a minimum, mild depression and/or anxiety symptoms were randomized to meditation and standard CR or to standard CR alone. A 16-minute guided group meditation was delivered face-to-face once a week for 6 weeks, with daily self-guided meditation practice between sessions. Feasibility outcomes included screening, recruitment, and retention. Semistructured interviews of patients' (n = 10) and health professionals' (n = 18) perspectives of intervention participation and delivery were undertaken to assess acceptability. Between-group differences in depression, anxiety, stress, self-efficacy for mindfulness, and health status at 6 and 12 weeks were also assessed.

Results and conclusion: Meditation was considered feasible, with 83% (12/15) of the intervention group completing an average of 3.13 (SD, 2.56) out of 6 group meditation sessions and 5.28 (SD, 8.50) self-guided sessions. Meditation was considered acceptable by patients, clinicians, and health managers. Between-group differences in the number of CR sessions completed favored the intervention group in per-protocol analyses (intervention group vs control group, 12 vs 9 sessions; P = .014), which suggests that meditation may be useful to improve patients' adherence to exercise-based CR program.
