Abstract
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 patient'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.
