Summary

The aim of this pilot randomized controlled trial was to evaluate whether adding a 16-week structured meditation intervention to a long-term (phase III) cardiac rehabilitation program reduces perceived stress and improves anxiety, depression, and health-related quality of life in patients with stable coronary artery disease. Patients were randomized 1:1 to standard cardiac rehabilitation plus meditation (experimental group) or standard cardiac rehabilitation alone (control group). The meditation intervention consisted of four weekly 90-minute group sessions followed by 12 weeks of daily individual practice supported by weekly follow-up calls. Outcomes were assessed at baseline and after 16 weeks.

Meditation Program

A 16-week structured meditation program added to standard cardiac rehabilitation. During the first month, participants attended four weekly 90-minute group sessions led by a physiotherapist trained in meditation techniques. Each session included: (1) a 30-minute thought-sharing and Q\&A moment; (2) a 30-minute conscious breathing protocol combining diaphragmatic abdominal breathing in a 1:2 inhale-to-exhale ratio and heart-focused breathing; and (3) a 30-minute guided meditation combining Karuna (compassion) and Metta (loving-kindness) practices. During the subsequent 12 weeks, participants practised individually for 20 minutes per day, supported by a recorded video by the same instructor and weekly follow-up telephone calls to maintain engagement and address questions.

OTHER

Exercise-based Cardiac Rehabilitation (standard)

Standard long-term (phase III) exercise-based cardiac rehabilitation program delivered three times per week (60 minutes per session) on non-consecutive days, supervised by exercise physiologists. Each session included a 10-minute warm-up and cool-down. Moderate continuous aerobic training was prescribed at 40-75% of heart rate reserve for 20-25 minutes per session using cycle ergometers or treadmills. Resistance training was performed after the aerobic component (1-2 sets of 8-12 repetitions at approximately 60-80% of one-repetition maximum, with 2-3 minutes rest between sets), according to European Society of Cardiology guidelines. Heart rate was monitored with a chest band.
