Introduction: Augmented incidence of anxiety is associated with Coronary Artery Bypass Graft (CABG) compared to other surgeries; it affects the function of vital organ. Preoperative anxiety may persist after surgery and affects health related quality of life. Music therapy is found to have an impact on patientâ€™s anxiety.
Aim: To find the effect of music therapy on hospital induced anxiety and Health Related Quality of Life (HRQoL) in patients after CABG.
Materials and Methods: Forty participants were recruited for the study, (age group 30-80 years) and randomised into two groups. The intervention group received music therapy along with cardiac rehabilitation and control group received cardiac rehabilitation alone once in a day. The primary outcome measure was Hospital Anxiety and Depression Score (HADS) was measured by a trained physiotherapist on preoperative day and postoperative day 2 and 7. The secondary outcome measures were SF-36 and 6 minute walk distance, measured by a trained physiotherapist on preoperative day and post operative day 7.
Results: HADS anxiety score showed significant difference within the intervention as well as control group, with p-value <0.05. The p-value of HADS depression component was <0.05 within each group. The values show that there is the reduction in both anxiety and depression in both groups nevertheless the p-value between the group was >0.05, which showed that there is no significant difference in HADS score between groups. The p-value of 6 MWT between the group was >0.05, but showed significant difference in control group. Physical component of SF-36 outcome did not show significant difference between the groups with p-value >0.05. Mental component of SF-36 did not established significant improvement between the groups. There was significant improvement in Physical component of SF-36 within the intervention group.
Conclusion: Both Phase I cardiac rehabilitation and music therapy has positive impact on anxiety, with music therapy being the most advisable.
