Objective: to evaluate the effectiveness of using music to relieve pain and anxiety in adult and elderly patients undergoing cardiac catheterization. Method: this is a systematic review with meta-analysis, carried out in October 2022, in 13 national and international data sources. The mnemonic “Population, Intervention, Control, Outcomes, Study design” (PICOS) was adopted for the elaboration of the research question. Randomized Clinical Trials (RCTs), involving patients aged 18 years or older, with no time or language restriction, were included, and studies that did not respond to the proposed research question were excluded. The present study was registered on the International Prospective Register of Systematic Reviews (PROSPERO) platform and followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: the sample consisted of nine studies included in the quantitative and qualitative synthesis of the data. The studies were mostly published in Germany (22.22%), Iran (22.22%) and Turkey (22.22%), in the years 2005 to 2022. 1,324 patients were included, in the age group of 18 to 84 years, whose anxiety assessment was given, above all, by the State-Trait Anxiety Inventory (STAI) (66.67%) and Numeric Rating Scale (NRS) (33.33%). Of the nine total studies, only three mentioned pain assessment, using the following scales: Visual Analog Scale (VAS) (22.22%) and Numeric Rating Scale (NRS) (11.11%). The preferred route for performing cardiac catheterization was the femoral (44.44%), followed by the brachial (22.22) and radial (11.11%). The parameters evaluated were anxiety, pain, systolic and diastolic blood pressure, heart and respiratory rate. There was a reduction in these parameters in the experimental groups due to the use of music, especially instrumental (44.44%), slow and relaxing (44.44%), applied through headphones (44.44%) or loud speaker (33.33%), in a time interval of 15 to 45 minutes, with melodies of 60 to 80 beats per minute (55.55%), in a sound intensity of 60 to 70 decibels (33.33%). Conclusion: music is considered a low-cost, non-pharmacological strategy that increases the humanization of care and is effective in reducing pain and anxiety levels in patients undergoing cardiac catheterization.
