Cardiovascular diseases are among the most significant health issues threatening human well-being, representing the leading cause of mortality and morbidity worldwide and in our country among non-communicable diseases. In Turkey, 33.4% of deaths are attributed to circulatory system diseases and ischemic heart diseases, with coronary artery disease (CAD) being the most common cause. The most frequently applied and accurate invasive diagnostic method for diagnosing CAD is coronary angiography. Coronary angiography, still regarded as the gold standard today, is a diagnostic procedure that visualizes the heart's blood vessels using contrast media. This procedure can be performed via the femoral, brachial, radial, or axillary arteries. In the past, coronary interventional procedures were commonly performed through the femoral artery. However, following the 2017 European Society of Cardiology (ESC) guidelines on ST-segment elevation myocardial infarction (STEMI) management, the radial artery has become the preferred route due to its lower risk of bleeding and shorter hospital stays. Coronary angiography is performed in a sterile environment while the patient is awake. Due to its invasive nature and the involvement of a vital organ, coronary angiography can evoke anxiety and fear of death in patients. Factors contributing to this include uncertainty about the procedure, unfamiliarity with the environment, communication with unknown personnel, exposure to medical terminology, and unusual sounds in the procedure room. The radial artery is more prone to vasospasm than other vessels used in coronary angiography, due to its smaller diameter and rich smooth muscle content. Local anesthesia is administered at the access site to reduce pain during radial artery interventions. Additionally, anticoagulant and vasodilatory drugs are used to prevent procedure-related vasospasms and thrombotic events. Despite these preventive measures, vasospasm is observed in 4-20% of patients undergoing transradial coronary angiography. Anxiety experienced by patients during the procedure can also contribute to vasospasm in the radial artery. Various invasive and non-invasive interventions, such as listening to music, acupressure, and massage, are frequently employed to reduce patient anxiety. Among these non-invasive methods, providing music during the procedure has gained prominence. Music helps divert patients' attention, enabling them to distance themselves from pain, fear, stress, and anxiety.
