Nevertheless, most of these complaints are benign and of non-coronary origin. Computed Tomography (CT) is the main diagnostic tool to investigate the coronary arteries, an examination with a low probability of false-negative result (&amp;lt;1%). Despite negative findings of CAD, this patient group still experience higher degree of morbidity and anxiety and decreased quality of life when compared to a population without chest pain. Purpose To determine the effect of an intervention for reliance in the CT-examination and recurring chest pain in patients with non-coronary chest pain in follow-up after one month. Methods Patients with chest pain, but with normal CT-findings, i.e. no CAD, were randomised into two groups. The intervention group received extended information about the examination, such as the reliability of the result due to CTs low probability of false-negative result and also the great prognostic value it provides. The examination result was then conveyed to the patient. The control group received standard care; i.e no extended information was given and the examination result was obtained from their general practitioner after one week. The effect of the intervention was measured with a specific question regarding reliance in the CT-examination and the Seattle Angina Questionnaire (SAQ) at follow-up after one month. Results The study included 92 patients; follow-up response rate was 80%. Of the participants were 63 females (68%), and the mean age was 51 years. Analysis showed that the intervention group had significantly higher reliance in the CT-examination (p = 0.016) and significantly reduced incidences of chest pain (p = 0.042) when compared to the control group at 1-month follow-up (Figure 1). Conclusion This intervention demonstrates that relatively simple actions may have a great impact on patient care. Providing patients with extended information and an early communication of CT results have a positive effect on reliance and chest pain after one month. Such an effect may lead to lower morbidity, less anxiety and a higher quality of life in this group. Further examinations after six or twelve months might provide additional knowledge of the long-term effect of the performed intervention. Abstract Figure 1
