The MULAN Trial - RCT on the use of MUsic in Cath-Lab to reduce ANxiety during peripheral vascular interventions.

Background: The purpose was to analyze the use of classical music to reduce procedure-related anxiety while conducting percutaneous transluminal angioplasty in patients with peripheral artery disease. Patients and methods: A total of 155 patients were analyzed in this single center randomized controlled trial. Procedure-related anxiety was assessed by a numerical rating scale (NRS, 0-10) and by recording of physiological parameters at three different points in time. A survey was conducted after the intervention. Results: This study showed that the patients listened to music overcame their procedure-related anxiety more quickly than the patients in the control group. The NRS at second timepoint was significantly reduced in intervention group compared to control group (p<0.01; r=0.2). Most participants stated that they would like to listen to music during possible future interventions. Conclusions: Classical music during endovascular interventions reduced procedure-related anxiety measured as greater reduction in NRS values in intervention group as well as in results of questionnaire performed post procedurally in PAD patients.
