Exploring the effect of music therapy as intervention to reduce anxiety pre- and post-operatively in CABG surgery: A quantitative systematic review.
Lan Wu, Yongbo Yao
PMID 37823363WHAT IT FOUND
Music before or after bypass surgery lowered anxiety more than no music in most studies, but not all.
Nurses can offer it as a low-risk comfort measure, but the best music and timing are unclear.
Key findings
01In the included studies, anxiety was lower with music than with no music overall, but one study found no significant difference.
02The review included five studies with 346 CABG patients, including four RCTs and one quasi-experimental study.
03Different anxiety scales, music types, durations, and timing prevented meta-analysis, so the best music and timing remain unclear.

What it does not show
The evidence base was small and heterogeneous. Several studies had risk of bias or incomplete outcome data. Not all included studies showed a significant effect. Different anxiety scales prevented pooling. Only English-language studies were included. The review did not determine the most effective music type, duration, or timing.
The easy way to misread this
Do not read this as proof that music therapy reliably reduces anxiety for every CABG patient. The studies were small and varied, not all showed benefit, and the review did not establish the best music, dose, or timing.
