A total of 30 blocks of three participants each were used. Within each block, the three participants were randomly assigned to the three groups so that each group received exactly one participant per block. The possible allocations for each block were the six permutations: (A, B, C), (A, C, B), (B, A, C), (B, C, A), (C, A, B), and (C, B, A). One of these permutations was then randomly selected using a random number table. N/A Patients who are candidates for coronary angiography. Intervention 1: Intervention group 1: The diaphragmatic breathing group, one hour prior to angiography, after obtaining informed consent, completing the demographic questionnaire and the HADS anxiety questionnaire, and measuring heart rate and blood pressure, will listen for approximately 20 minutes to an audio file containing the psychologist's guided instructions, soothing music, and step-by-step diaphragmatic breathing training. After the intervention, the anxiety questionnaire will be completed again, and heart rate and blood pressure will be re-measured. Intervention 2: Intervention group 2: The guided imagery group, one hour prior to angiography, after obtaining informed consent, completing the demographic questionnaire and the HADS anxiety questionnaire, and measuring heart rate and blood pressure, will listen for approximately 20 minutes to an audio file containing the psychologist’s guided instructions, soothing music, and step-by-step guided imagery training. Following the intervention, the anxiety questionnaire will be completed again, and heart rate and blood pressure will be re-measured. Intervention 3: Control group: The control group, one hour prior to angiography, after obtaining informed consent, completing the demographic questionnaire and the HADS anxiety questionnaire, and measuring heart rate and blood pressure, will receive routine care. Following the routine care, the anxiety questionnaire, heart rate, and blood pressure will be measured again.
