Introduction: An estimated 50-75% of visits to cardiac emergency departments are due to chest pain which is non-cardiac in nature (non-cardiac chest pain (NCCP). This study evaluates the prevalence of NCCP in the emergency departments at Landspitali, and assesses its association with continued chest-pain post discharge, mental well-­being and the information-provision provided to NCCP patients during hospitalization.

Material and methods: Participants were 390 patients (18-65 years) presenting with chest pain to the cardiac emergency or the general emergency department at Landspitali from October 2015-May 2016. Measurements included questionnaires assessing somatic symptoms, mental well-being and quality of life, and questions regarding continued chest-pain and information-provision during hospitalization.

Results: In total 72% of participants (282) were considered having NCCP while 24% (92) had cardiac disease. NCCP patients experienced a similar burden of somatic and depressive symptoms, but slightly more anxiety and mental distress than cardiac patients. Equal proportions (60%) of NCCP and cardiac patients reported having experienced chestpain post discharge. Continued chest-pain was, however, associated with greater anxiety (β=0.18, p<0.001) and depression (β=0.18, p<0.003) among NCCP patients. Thirty percent of NCCP patients lacked instructions of how to respond to continued chest-pain and only 40% received information regarding other possible causes of chest pain.

Conclusion: NCCP was prevalent among patients presenting to emergency departments at Landspitali. The majority of NCCP patients experienced continued chest-pain after discharge, and such pain experience was associated with mental distress. A third of NCCP patients lacked information about possible causes for the pain and advice about coping with symptoms.
