This study was conducted to determine the effect of music listened to during compulsory bed rest after coronary angiography on pain, anxiety and hemodynamic parameters experienced by patients. 80 patients were randomized into the music and control groups. The patients in the music group were allowed to listen to music (Sufi, relaxing, sounds of nature) preferred by them for 20-30 minutes half an hour after admission to the service for follow-up after angiography. No music was listened for the control group. The pain, anxiety, and hemodynamic parameters of the patients were measured before, immediately after, one hour after listening to music, and at discharge. Descriptive statistics, Student t, Mann Whitney U, Repeat Measurament, Fridman and Chi-square tests were used to evaluate the data. There was no statistically significant intergroup difference in terms of average scores of pain and anxiety and hemodynamic parameters at the baseline (p>0.05). The difference between the average scores of pain and anxiety between groups in all measurements after listening to music was found to be significant (p<0.05). The mean anxiety and pain scores of the patients in the study group were lower. In the study group, systolic and diastolic blood pressure, heart rate, respiratory rate decreased, and oxygen saturation increased in all measurements after listening to music (p<0.05).
