After explaining the purpose of the study and the way it was applied to patients in the music group, Introductory Information Form, State Anxiety Scale," "General Comfort Scale," and "Hemodynamic Parameters Record Form were applied. The intervention group listened to nature sounds (the sound of birds, water flowing in a river, wind or walking in the forest) based music during the angiography procedure.Music was played to the intervention group via a loudspeaker placed in the coronary angiography laboratory.The intervention group was reapplied the State Anxiety Scale, General Comfort Scale and Hemodynamic Parameters Record Form after the angiography procedure.

After explaining the purpose of the study and the way it was applied to patients in the control group, Introductory Information Form, State Anxiety Scale," "General Comfort Scale," and "Hemodynamic Parameters Record Form were applied. No application was be made to the control group. The control group was reapplied the State Anxiety Scale, General Comfort Scale and Hemodynamic Parameters Record Form after the angiography procedure.

Listening to nature sounds (the sound of birds, water flowing in a river, wind or walking in the forest) based music during the angiography procedure.

Scores from the scale range from 48 to 192, and the higher the score, the higher the comfort level.

Scores from the scale range from 20 to 80, and the higher the score, the higher the anxiety level.

The form was used to record the Systolic Blood Pressure (mm/Hg), Diastolic Blood Pressure (mm/Hg), Respiratory Rate, Heart Rate (Pulse) (atm/min) and Saturation parameters measured before and after the angiography procedure of the intervention and control groups.

Systolic blood pressure measurements were averaged. Diastolic blood pressure measurements were averaged. Saturation measurements were averaged. Respiratory rate measurements were averaged. Heart Rate (Pulse) measurements were averaged.
