Coronary angiography is used to visualize coronary arteries and to diagnose coronary artery diseases. After the examination a percutaneous coronary intervention (PCI) can be performed as treatment. This examination can cause anxiety and fear among patients which may cause physical symptoms such as increased heart rate and blood pressure that can have negative effect on the examination and the possible intervention. The radiographer has primary responsibility for patient care during the examination. In order to provide the most optimal care to patients, the radiographer has to have knowledge of the underlying causes to anxiety and fear related to coronary angiography. The aim of this literature review was to compile knowledge that describes factors affecting patients’ experiences of anxiety and fear before a coronary angiography with or without PCI. The study was performed as a literature review. Eleven scientific articles were reviewed, analyzed and the results were presented in categories. Five categories that describe factors affecting patients experience of anxiety and fear were identified: Socio-demographic factors, Previous experience of coronary angiography or PCI, The impact of information on the experience of anxiety and fear, Experience of anxiety and fear related to the examination situation and Anxiety and fear related to the examinations impact on the patients everyday life and future. To recognize factors that influence anxiety and fear in coronary angiography patients’ enables the radiographer to select the most appropriate nursing interventions for every individual patient. To be able to reduce patients’ anxiety and fear during the short meeting as he or she arrives to the examination room individually adapted information is of great importance.
