Vital Parameters Variations in Patients Undergoing Music Therapy During Cardiac Catheterization Procedures: A Preliminary Study

Abstract Background: Invasive cardiac procedures, such as coronary angiography, are known to induce patient stress and alter physiological parameters by triggering the sympathetic nervous system. While music is recognized to reduce anxiety, insufficient data exists regarding its specific physiological impact during these interventions. Unlike previous studies, which often utilized pre-selected tracks administered by non-specialized staff, this preliminary study investigates whether a personalized music therapy intervention, managed by a qualified therapist, has apositive impact on vital parameters. Methods: This prospective, single-center study compared 36 patients receiving personalized music therapy (experimental group) versus 36 controls (final cohort). The intervention involved a pre-procedural meeting for the therapist to assess musical preferences, establish rapport, and conduct a shared listening session. Vital parameters (Blood Pressure, Heart Rate, Heart Rate Variability, and O2 Peripheral Saturation) were analyzed across four distinct procedural phases. Results: A statistically significant reduction in sedation requirements was observed in the music therapy group (11.8%) compared to the control group (44%) (p
