Study of the effectiveness of musical stimulation during intracardiac catheterization.

Background: Intracardiac catheterization is a routine physical examination. Due to psychological strains, several psychosocial interventions, including music therapy, have been proposed. The aim of the present study was to examine whether the preventive or adjuvant use of music therapy results in a reduction in both subjective and objective anxiety and thus leads to a reduction in sedative medication. METHODS OF ASSESSMENT: N=83 patients (48 male, 35 female, 66+/-11 yrs) waiting for scheduled cardiac catheterization were randomly allocated to one of three groups: control group (standard care), exposure group (music stimulation during the procedure), or coaching group (additional music therapeutic coaching). Target variables were subjective anxiety and physiological parameters.

Results: Music intervention did effectively reduce subjective anxiety (STAI-S reduction pre-post: exposure 11 pt, coaching: 4 pt, control: 6 pt; p=0.033). Physiological values and medication did not differ between groups.

Conclusion: The use of music stimulation during the catheterization has a relaxing and calming effect on patients. It seems to be especially beneficial in a subgroup of patients with higher-than-average psychological strains.
